Chapter 38 - Interogation

When the Greater Daemon of Slaanesh's avatar—a colossal, twisted, chitin-armored horror, its upper body wielding countless terrifying claws with suckers and venomous barbs—struck down with unparalleled force again, Yvraine's full-power Death Barrier shattered like fragile glass!

The psychic shield of the "Soul Song Blade" let out an overwhelmed wail, collapsing instantly! The torn Warp rift, like a breached dam, unleashed an even more furious torrent of Slaanesh Daemons, carrying mind-maddening sweet whispers and sensory storms, crashing into the ship's interior!

"For pleasure!"

"Embrace eternity!"

"Flesh! Soul!"

The first to rush in were a group of screaming Slaanesh Daemonettes, twisting and dancing, their sharp claws lunging at the closest Aeldari crew. Some of the weaker-willed Aeldari were instantly bewitched by the powerful sensory assault, their eyes gleaming with intoxication, actively welcoming the Daemons. The next second, their souls were ripped out and devoured, their bodies slumping to the ground like withered flowers.

Chaos and death instantly spread!

However, at this critical moment—

"For the Emperor! For Macragge! Fire!"

Sergeant Golden's roar, like a clap of thunder, shattered the Daemons' clamor!

Twenty Ultramarines Terminators, already poised, simultaneously raised their Bolters and heavy weapons! In an instant, a storm of scorching metal, like an angry dam, slammed into the Daemon tide!

Bang! Bang! Bang! Bang! Bang!

Deafening Bolter fire instantly filled the entire command bridge! Bolter rounds were a devastating blow to these Slaanesh Daemons, who were not known for their physical defenses! The Daemonettes and Plaguefly swarms at the forefront were struck as if by an invisible giant hammer, instantly exploding into a shower of foul flesh and shattered chitin!

The roar of chainswords followed! Golden, Dorian, and other melee warriors, like blue steel fortresses, stood at the very front, using their heavy armor and immense strength to forcefully block the Daemon charge, then hacking and smashing them to pieces!

"Protect Yvraine! Nothing must happen to her!" Golden roared, parrying a Keeper of Secrets avatar with his power sword. He knew that no matter how much they distrusted the Aeldari, Yvraine, as the leader of the Ynnari and the key to this cooperation, absolutely could not be harmed at this moment.

The Ultramarines quickly tightened their formation, protecting the weakened Yvraine and her core advisors in the center, forming a solid bulwark with concentrated firepower and bodies of steel, fending off the Daemons surging from all directions.

But the situation remained critical. The Daemons were too numerous, and the terrifying pressure from the Greater Daemon avatar still lingered. Its massive tentacles were wreaking havoc elsewhere, attempting to completely dismantle the ship's resistance.

"Damn it! I knew these bean sprouts couldn't hold them off!" Captain Cassius of the 7th Company, watching all this from the Unyielding Will via monitoring, slammed his fist on the command console in anger. "7th Company, all units! Prepare for boarding action! Fist of Contrition, provide fire support! Blast these damned Chaos scum back to the Warp!"

The Unyielding Will and the Fist of Contrition, the two Imperial strike cruisers, immediately surged forward like enraged beasts, engines at full throttle, charging towards the "Soul Song Blade." Their broadside macro-cannons and laser arrays began to flicker, preparing for precise fire support.

Just at this moment of extreme chaos—

Three silver lightning bolts, like the dawn light tearing through darkness, suddenly burst from the strictly sealed compartment! It was Moreno, Valerius, and Kaldor, the three Grey Knights!

Their silver-grey armor stood out like lighthouses in the dim, chaotic battlefield, surrounded by pure and cold psychic flames. Wherever they passed, the nauseatingly sweet scent of Slaanesh seemed to be purified and dispelled!

"Profane creatures! How dare you appear here!" Valerius's roar was like thunder. The Daemonhammer in his hand gathered immense psychic energy, shining like a small sun! He took a mighty step forward, and the great hammer crashed down!

Boom—!!!

A fan-shaped shockwave, composed purely of destructive psychic energy, surged forward! Slaanesh Daemons caught in this shockwave, whether Daemonettes, Plagueflies, or Keeper of Secrets avatars, didn't even have time to scream before instantly dissolving and purifying like snow in sunlight, leaving not a trace of residue! A single blow cleared a large area!

Kaldor, meanwhile, moved like a phantom among the Daemons. The psychic sword in his hand transformed into threads of deathly light, and with every flash, a Daemon was precisely cleaved in two, psychic flames erupting from within the wound, utterly incinerating and purifying it. His movements were elegant and efficient, as if he were not killing, but performing a sacred ritual of cleansing defilement.

And Captain Moreno, though his Vengeful Goddess Power Halberd had been destroyed in the battle with the Great Unclean One, his power was undiminished! He raised both hands, and immense psychic energy condensed and shaped in his grasp, instantly forming a colossal and majestic power halberd made entirely of pure, silver-white psychic energy!

His gaze instantly locked onto the massive Greater Daemon of Slaanesh avatar that was frantically attacking a Wraithlord, almost tearing the spirit-bone construct apart!

"In the Emperor's name! Purify!"

Moreno let out a declaration like one from the ancient Inquisition, his form vanishing instantly from his spot, only to reappear a moment later directly above the Greater Daemon avatar! He raised the psychic halberd with both hands, and his entire body plunged like a meteor, the halberd carrying supreme purifying will, forcefully piercing the center of the Greater Daemon avatar's smooth chitin armor!

Screech—!!!

Like a hot knife through butter, the psychic halberd penetrated without resistance! Immediately after, terrifyingly pure psychic energy erupted like a bomb from within the Greater Daemon avatar's body!

"Aargh—!!!" The Greater Daemon of Slaanesh avatar let out a scream of extreme pain and fury. Its massive body convulsed violently, swelled, and finally exploded in a dazzling silver-white light! Countless foul fragments splattered everywhere, but were utterly purified the moment they touched the psychic radiance!

This terrifying blow not only instantly annihilated the most threatening Greater Daemon avatar, but its explosive pure psychic shockwave also swept across the entire battlefield, greatly weakening the remaining Daemons' power, and even causing the Warp rift to fluctuate violently, no longer spewing forth new Daemons! All of this happened extremely quickly, from the Grey Knights' appearance to the purification of the Greater Daemon avatar, in just a matter of ten-odd seconds!

The precarious battle situation was instantly reversed!

Yvraine, supported by the Visarch, stared blankly at the three silver figures who had descended like divine warriors, watching them slaughter the Slaanesh Daemons that she and her people had found incredibly difficult to deal with, with overwhelming might. Especially Moreno's terrifying power in purifying the Greater Daemon avatar with a single blow, her pale face for the first time showed an expression of disbelieving shock.

Although she had long known that the Grey Knights were one of the Empire's ultimate forces against Chaos, hearing about it and seeing it with her own eyes were two completely different things. This absolute suppression and destructive power against Chaos Daemons made her deeply understand what "Chaos Bane" meant! Compared to the Grey Knights, the Ynnari's suppression of Daemons even seemed somewhat... gentle.

A wave of lingering fear and self-reflection surged within her. They had indeed been careless, overly reliant on their conventional understanding of Slaanesh and the power of ynnead, completely failing to anticipate such a powerful Greater Daemon avatar appearing directly, almost leading to their complete annihilation and even dragging their Imperial allies into despair.

Under the combined efforts of the Grey Knights and Ultramarines, the Daemons inside the ship were quickly eradicated. The Warp rift, having lost the support of the Greater Daemon avatar and the interference of the Grey Knights' powerful psychic energy, began to gradually shrink and close, eventually disappearing completely, as if it had never appeared. Clearly, the Chaos faction had also completely failed to anticipate the Grey Knights' presence here, and continuing to commit forces would only incur further losses.

The battlefield temporarily returned to calm, leaving behind only widespread wreckage, the bodies of Aeldari crew, and the faint smell of char from the purified Daemon remains.

Just then, Captain Moreno, accompanied by Valerius and Kaldor, walked with heavy steps towards Yvraine, who was protected in the center by the Ultramarines. The silver-grey armor still glowed with the afterglow of burning psychic energy, and beneath the cold, aquiline helmet, their gazes fell upon Yvraine with palpable intensity.

Yvraine was still very weak and was about to open her mouth to express thanks and an explanation—

Suddenly! Moreno, without warning, abruptly reached out. His silver-armored hand was as fast as lightning, seizing Yvraine's slender neck and actually lifting her off the ground!

"Ugh!" Yvraine was caught off guard. A violent sense of suffocation and pain instantly struck her. Her hands instinctively grasped Moreno's iron-vice-like arm, but she couldn't move it an inch. Her face quickly turned red from lack of oxygen, and her legs hung limply.

"My lord!" The Visarch and several Ynnari warriors were shocked and enraged, immediately attempting to rush forward to rescue her.

But the surrounding Ultramarines Terminators instantly moved, encircling them like a cold steel wall, their Bolters and power weapons unceremoniously pointed at them, preventing any further movement. The atmosphere instantly became tense again!

"Xenos!" Moreno's cold, stern voice, brimming with towering rage, rang out through his faceplate. Every word pierced the air like an ice pick. "How dare you lead the Emperor's warriors into such a foul and treacherous place, to face the threat of a Greater Daemon! You owe us an explanation! Otherwise, today shall be the day of your and your ship's complete purification!"

His anger was not without reason. In the eyes of the Grey Knights, exposing the elite forces of the Imperium to such a powerful Chaos threat was in itself an extreme risk and an irresponsible act, especially when guided by Xenos.

After speaking, Moreno, as if discarding a piece of trash, violently threw Yvraine heavily to the ground.

Yvraine coughed violently, gasping for air, clear metallic finger marks left on her neck. The Visarch immediately broke free (the Ultramarines had not truly restrained him) and rushed to her side, watching the Grey Knights warily.

Yvraine slowly raised her head, looking at the three silver-armored giants before her, like cold judges. A flicker of humiliation crossed her eyes, but more so, a complex emotion. She gasped, her voice hoarse, saying:

"Grey Knights... sirs... please calm your anger... This time... it was indeed our... misjudgment... we underestimated Slaanesh... and the forces committed this time..."

She explained haltingly, with a hint of lingering fear and honesty in her tone: "We... based on previous intelligence... did not anticipate... a Greater Daemon's... high-level avatar... directly manifesting... A regular Daemon tide... the Ynnari would have been sufficient to handle... But this time..."

She took a deep breath, trying to steady her voice: "...But the intensity of this attack... far exceeded expectations... It's as if... Slaanesh sensed... something... and specifically amplified its power... This in itself... is extremely unusual..."

Moreno's cold optics stared at her, not immediately softening due to her explanation: "Unusual? Do your words imply this was a deliberate trap set by Chaos? Or merely an excuse for your incompetence?"

Valerius, at his side, added coldly: "The words of xenos should always be viewed with the greatest malice. Perhaps this is a scheme between you and Chaos, intended to deplete the Imperium's strength, or... to test the existence of the Grey Knights."

Yvraine's face flashed with a hint of bitterness upon hearing this, and she shook her head: "No... Grey Knight Sir... Though we are xenos, the path of ynnead... is the absolute mortal enemy of Chaos... there is no possibility of cooperation... This mistake... was due to my over-reliance on past experience... and my overconfidence in the power of the Ynnari... nearly leading to disaster... I am willing to bear... all responsibility..."

She raised her head, her gaze frankly meeting Moreno's: "But please believe... the threat of Slaanesh... is no empty talk... Its abnormal increase in power... is a common crisis for us... If not for your intervention today... we would all have become fodder for Chaos... This kindness... the Ynnari will remember forever..."

Her attitude appeared sincere and remorseful, with no attempt to shirk responsibility.

Moreno was silent for a moment, seemingly evaluating the truthfulness of her words. His powerful psychic perception could detect that Yvraine's emotional fluctuations were filled with lingering fear, shock, and a determination to resist Chaos, with no signs of deception.

Finally, he snorted coldly, and the icy psychic pressure receded slightly: "It had better be. Remember this lesson, xeno. The Emperor's patience and mercy are not limitless. If there is a next time, or if the Imperium suffers significant losses due to your mistakes..."

He did not finish, but the unspoken threat carried more weight than any words.

"Let's go." Moreno no longer looked at her, turning and leading Valerius and Kaldor, just as they had arrived, like three moving silver mountains, leaving the command hall and returning to their quarters. It was as if the thunderous fury and rescue had just been routine.

The Ultramarines also stood down from alert but maintained their surveillance posture.

Yvraine slowly stood up with the Visarch's support, looking in the direction where the Grey Knights had departed, her eyes filled with immense complexity. Today's experience had taught her a heavy lesson. The war with Chaos was far more brutal and unpredictable than she had imagined. And the power possessed by the Imperium, especially the hidden grey blade, far exceeded her estimations.

The path of cooperation was destined to be filled with thorns and suspicion, but for survival, they had to continue down it.

After the Grey Knights left, the atmosphere in the command hall remained solemn, but the deadly tension gradually dissipated. The air was filled with the faint smell of ozone after psychic purification, the burnt odor of demon remnants, and a faint scent of blood. The Aeldari crew began to silently clear away the bodies of their companions and repair damaged equipment. Their faces showed sadness and lingering fear, yet their movements still maintained the Aeldari's characteristic elegance and efficiency, though this elegance now seemed particularly heavy.

Yvraine, supported by the Visarch, slowly walked to Sergeant Golden. She nodded slightly, and although the finger marks on her neck were still clearly visible, her tone had returned to its previous calm, only now with a genuine sense of gratitude and apology:

"Sergeant Golden, and all the brothers of the Ultramarines, thank you for your timely assistance. If not for your iron bulwark and... the thunderous power of the Grey Knight Sirs, the 'Soul Song Blade' would likely have fallen today, and we would all have been doomed."

She paused, her voice lowering a few octaves: "This crisis was entirely due to my command error and underestimation of the enemy. I deeply apologize for our misjudgment and for involving you all in such peril. The Ynnari owe you a heavy debt of gratitude."

Sergeant Golden looked at this Aeldari leader who had just experienced life and death, and had even been roughly treated by the Grey Knights, yet still maintained her composure. His vigilance had not decreased, but a very subtle sense of recognition, born from their shared battle, inevitably increased by a fraction. He responded in a deep voice: "Lady Yvraine, we have received your thanks and apologies. But as Captain Moreno said, we hope such 'incidents' do not happen again. The Imperium's strength is not a pawn to be casually expended."

His words still carried a tone of reminder and warning.

"I understand." Yvraine nodded solemnly, "We will re-evaluate intelligence and strengthen our defenses. Furthermore..." She looked at Dorian, who had just received Aeldari medical treatment and was flexing his arm, "We will take full responsibility for this warrior's injuries, ensuring his complete recovery."

Dorian, hearing this, grumbled: "Hey, don't say it, your green potion is quite effective, feels even more potent than Apothecary Vorlak's strong medicine!" His words lightened the tense atmosphere somewhat.

Golden glared at Dorian, who immediately shrunk his neck.

At that moment, Captain Cassius's holographic image reappeared, his expression serious: "Lady Yvraine, Sergeant Golden. The crisis is temporarily averted, but a full report on this matter is required. I need both of your parties to provide detailed combat logs and incident analysis. Furthermore, in light of this incident, subsequent cooperative actions must be more cautious. All operations are suspended until new assessment results are obtained."

"Agreed, Captain Cassius." Yvraine immediately responded, "We will fully cooperate with the investigation and provide all relevant information we possess."

Soon, the Imperium's Tech-Priests and the Aeldari's technical personnel began to interface, downloading starship logs, combat records, and sensor data. Luna also participated, her bionic eye constantly flickering, ensuring the secure and reliable transmission of data, and performing initial cross-verification of the data provided by the Aeldari.

During the intervals of data transmission and analysis, Yvraine came alone to the observation deck, gazing at the gradually calming starry sky outside the window, and the two Imperial strike cruisers that stood like loyal escorts. Her heart was far from as calm as it appeared on the surface.

The absolute power displayed by the Grey Knights, and Moreno's merciless questioning and threats, had deeply affected her. She had originally believed that with the Ynnari's unique counter to Chaos and the Aeldari's psychic mastery far exceeding humanity's, they would be able to hold a certain initiative, or even advantage, in cooperation. But now she understood that in front of the Imperium's war machine, especially in front of the Grey Knights who existed solely to destroy Chaos, their meager strength and pride seemed so fragile.

"We... were indeed too confident." She murmured to herself, as if reflecting, or perhaps speaking to the unseen ynnead, "One could even say arrogant. Believing we had grasped the true meaning of death, we could look down upon the struggles of all beings... yet we forgot that the essence of Chaos is to transcend reason, to be endless variables and madness."

The Visarch appeared silently behind her, like a loyal shadow.

"My Lady, you need not blame yourself too much." The Visarch's voice remained stern but carried concern, "No one could have predicted the Greater Daemon's avatar would personally descend. This in itself is a highly unusual signal."

"It is precisely this 'unusualness' that is more concerning, Visarch." Yvraine turned around, her eyes sharpening, "Why would Slaanesh suddenly commit such powerful forces? Is their goal truly just to randomly choose a location to invade? Or... have they sensed something? For example... our cooperation? Or... some special presence on board?"

Her thoughts drifted to the three Grey Knights. The very existence of the Grey Knights held a strong attraction for Chaos; their psychic power was like a lighthouse in the darkness. Had Slaanesh come for them?

Or perhaps... her gaze inadvertently swept over Kal, who was talking to Golden in the distance. This human warrior also seemed to hide some ineffable quality, tightly intertwined with the threads of fate... She shook her head, temporarily suppressing these chaotic thoughts. The immediate priority was to mend relations, regain trust, and ascertain the true reason for Slaanesh's abnormal movements.

In the Grey Knights' exclusive quarters, Moreno, Valerius, and Kaldor were gathered around a psychic focus emitting a faint silver light, meditating and debriefing.

"The xenos' mistake nearly led to disaster." Valerius's voice carried a hint of lingering anger, "Their understanding of Chaos's malevolence is still superficial."

Kaldor, however, focused more on technical analysis: "However, some of the data they provided shows an abnormal surge in Slaanesh's energy readings recently, inconsistent with previous patterns. This is not entirely a lie."

Moreno slowly opened his eyes, silver light swirling within them: "The truth is equally important. The survival of xenos is insignificant to the Emperor's grand design. However, the unusual movements of Chaos must be thoroughly investigated. The intensity and targeting of this attack are out of the ordinary. The shadow of Tzeentch may be behind it, or... a deeper conspiracy."

They unanimously agreed that although the incident was perilous, it also revealed important information. Slaanesh's activity was indeed abnormally high, and its behavior patterns had changed. The underlying reasons for this might be more important than the current Aeldari cooperation.

"Continue surveillance. Focus on the movements of the xenos, and... the reactions of that particular warrior (Kal) who is under special observation." Moreno issued the command. Even after fighting together, their core mission had never changed.

Several hours later, the preliminary data analysis report was presented to Captain Cassius and Yvraine. The report confirmed Yvraine's statement that Slaanesh's energy fluctuations were indeed abnormal, and some uninterpretable, atypical Warp interference signals were detected, which seemed to have guided or amplified the demonic attack.

Although the specific reason could not be determined, this at least partially cleared the Ynnari of suspicion of "deliberately setting a trap."

Captain Cassius's attitude softened slightly, but he still emphasized: "Intelligence work must be strengthened. The next operation must have a more comprehensive plan and contingency measures. The lives of Imperial warriors must not again be placed in such uncontrollable risk."

Yvraine solemnly promised: "We will use all resources to thoroughly investigate the root cause of Slaanesh's unusual activity. Before the next operation, we will certainly share more accurate intelligence and a more secure plan."

Inside the bridge of the Unyielding Will, Captain Cassius, using a highly encrypted channel, reported everything that had happened on the "Soul Song Blade" to Chapter Master Marius Calgar, who was far away on the Macragge's Honour. This included the sudden attack by the Greater Daemon of Slaanesh's avatar, the decisive intervention of the Ultramarines, the thunderous purification by the Grey Knights, and the subsequent tense standoff, all without reservation.

Chapter Master Calgar, in the holographic projection, listened silently. His resolute face showed little emotion, only his deep-set eyes narrowed slightly, and his fingers unconsciously tapped the armrest of his throne.

When Cassius finished his report and waited for instructions, Calgar was silent for a moment before speaking slowly, his voice steady but with a hint of undetectable doubt:

"The Ynnari... are not weak. Their understanding of Chaos, especially Slaanesh, should be far superior to ours. Given their past demonstrated abilities and ynnead's power to counter Slaanesh, a conventional daemon incursion should never have left them in such a predicament, almost resulting in the destruction of their ship and loss of life."

He paused, his gaze sharpening: "Such carelessness, allowing a Greater Daemon's avatar to manifest directly within... This is illogical. Could it be..."

His thoughts seemed to drift elsewhere, recalling Captain Cassius's earlier investigation into the intelligence system being interfered with by external forces.

"Cassius," Calgar's voice grew deeper, "do you remember the 7th Company's earlier report? About the possible existence of some force intercepting or modifying critical intelligence from outside."

Cassius's heart tightened: "Are you suggesting..."

"Perhaps, this time is no exception," Calgar speculated. "There might have been a warning about a Greater Daemon's avatar hidden within this Slaanesh vanguard, but during transmission, it was intercepted or tampered with by that mysterious third-party force. This would have prevented Yvraine and your forces from receiving complete and accurate intelligence, leaving the Ynnari unprepared and causing them to lose some of their warriors."

This deduction was logical and perfectly explained why the experienced Ynnari would make such a "low-level" mistake. If the intelligence itself was distorted, then any tactical deployment would be built on quicksand.

"In that case, the suspicion that Yvraine deliberately led the Imperial forces into a dangerous area can largely be ruled out," Calgar concluded. "She herself was in grave danger, even nearly dying, which cannot be explained by a feigned attack."

However, the removal of suspicion did not mean complete trust.

"But, surveillance must not be relaxed," Calgar emphasized. "The manipulator hidden behind the scenes, their motives are unknown; it could be Chaos, or other factions. We must remain vigilant at all times. Notify Captain Moreno that until there is concrete evidence of Ynnari betrayal, no aggressive actions are to be taken against our temporary allies. The honor of the Imperium must not be tarnished."

He then changed the subject, issuing new orders: "At the same time, instruct them, including your forces, to pay special attention to receiving and analyzing information from all sources, especially reports of small-scale, abnormal Chaos activity. Should any signs of information being tampered with or intercepted be detected, immediately raise the alert level and report to me. What we face may not be merely the Slaanesh before us."

"Understood, Chapter Master!" Cassius solemnly accepted the order. The Chapter Master's analysis was like clearing the clouds to see the sun, giving him a clearer understanding of the complex situation at hand.

After ending the call with the Chapter Master, Cassius immediately contacted Sergeant Golden, who was still on the "Soul Song Blade."

"Golden, the Chapter Master has new instructions," Cassius relayed the Chapter Master's analysis and orders. "...Based on these judgments, the Chapter Master believes that the Ynnari's mistake this time was likely not intentional, but rather due to a third-party force at work behind the scenes, tampering with critical intelligence."

He paused, saying with a subtle tone: "Therefore, the Chapter Master requests... that you, representing our side, apologize to Ms. Yvraine and express regret for Captain Moreno's previous... overly aggressive actions. At the same time, inform them of our speculation about the intelligence possibly being tampered with, and remind them to also strengthen their information security."

Golden was stunned for a moment upon hearing this order. Apologize to an alien leader? This was truly... But he quickly understood the Chapter Master's deeper meaning. This was an active gesture of reconciliation, mending the rift, preserving room for potential future cooperation, and also demonstrating the Imperium's discernment and magnanimity.

"...Understood, Captain. I will handle it properly," Golden responded.

Soon after, in a relatively quiet rest cabin on the "Soul Song Blade," Sergeant Golden met Yvraine. Her complexion had recovered considerably, and the finger marks on her neck had faded significantly.

Golden, as ordered, expressed the Imperium's apology and speculation in the most formal and sincere tone possible.

"...Therefore, Ms. Yvraine, we believe this incident was likely not due to your oversight, but rather an unknown enemy manipulating events from the shadows, tampering with critical intelligence, which put both our sides in danger. For Captain Moreno's previous aggressive actions, I, on behalf of the Ultramarines Chapter, express regret. We hope both sides can put this unpleasantness behind us and continue to focus on confronting our common threat."

Yvraine listened quietly, a flicker of surprise in her deep eyes, which then transformed into a complex emotion. She had not expected the Ultramarines, known for their rigidity and arrogance, to proactively lower their stance to apologize and analyze the reasons. This subtly changed her perception of humans.

She nodded slightly, accepting the apology: "Sergeant Golden, thank you for your honesty. The Imperium's magnanimity impresses me. Your speculation... is very reasonable. In retrospect, many details of this attack do indeed raise questions, as if an invisible hand was at work. We will immediately begin investigating our internal information transmission system and strengthen its defenses."

She also took the opportunity to express her own stance: "I once again thank your side for your previous assistance. Especially you, Sergeant Golden, in the chaotic situation at the time, you decisively ordered the protection of me and my people. This kindness, the Ynnari will not forget."

Although her tone still carried the Eldar's characteristic elegance and aloofness, the previously evident arrogance seemed to have somewhat receded due to this setback and the Imperium's candor. Of course, the arrogance ingrained in her, stemming from her ancient race and chosen status, could not be completely removed; she seemed to selectively "forget" the embarrassment of nearly being choked unconscious by a Grey Knight, and instead focused on jointly confronting the external threat.

Golden nodded: "Fighting Chaos is our common duty."

After the brief exchange, the atmosphere between the two sides visibly eased. While complete trust would still take time to build, at least the bridge of cooperation had not been completely severed by this crisis.

The Ynnari demonstrated efficient recovery capabilities. Although they had lost some warriors and ship equipment, their core strength remained intact. In a very short time, they completed battle damage assessment, casualty treatment, and basic ship repairs. The mournful song of death once again echoed through the fleet, only this time, the song carried a deeper sense of solemnity and vigilance.

The reorganized Ynnari fleet remained a formidable force, not to be underestimated, specifically designed to counter Chaos.

The Unyielding Will and the Fist of Contrition also received new orders: to continue following the Ynnari fleet, maintaining surveillance and support, but to raise the intelligence vetting level, always ready to respond to unforeseen circumstances.

Soon, the combined fleet set sail again, leaving the asteroid belt that had just witnessed a bloody battle, heading towards their original destination—the Taranis Sector.

After this perilous test, the fragile alliance between the Imperium and the Eldar seemed to have grown somewhat more resilient, but they also became more clearly aware of the immense hidden risks. The third-party dark hand, capable of silently tampering with intelligence and manipulating both sides, hung like a sword over their heads, causing everyone a deep sense of unease.

The course remained the same, but the fog ahead seemed even thicker. The true conspiracy, perhaps, had only just begun to unfold.

The combined fleet journeyed through the cold void, steadily advancing towards the Taranis Sector. Having experienced the previous dangerous encounter, both the Ultramarines and the Ynnari were enveloped in a more cautious and somber atmosphere.

In a private meditation chamber on the "Soul Song Blade," Yvraine dismissed everyone, leaving only the Visarch. Her beautiful face was clouded with an impenetrable haze of doubt.

"Visarch," her voice carried a hint of weariness and deep confusion, "don't you find it strange? A Greater Daemon of Slaanesh's avatar, its power and aura like a candle in the night, should be impossible to completely conceal. Why, before its manifestation, did all our warning systems, deployed at Webway nodes and the fringes of reality, fail to detect even the slightest abnormal fluctuation?"

The Visarch stood silently, like a cold statue, but the eyes hidden behind his mask were also filled with solemnity: "It is indeed abnormal. It's as if... it wasn't naturally born from a nearby Warp rift, but rather... from an extremely distant place, forcibly 'dragged' by some power and precisely delivered right before us."

This conjecture was chilling. If there truly was an entity capable of so precisely manipulating Greater Daemon-level demons for inter-dimensional deployment, then its power and understanding of the Warp would reach a terrifying degree.

Yvraine's fingertips unconsciously traced the star map formed by psychic energy before her, trying to find clues: "Has Slaanesh's own power grown stronger? Or... as those humans suspect, is there a third party manipulating things in the dark? And what is their purpose? To provoke conflict between us and humanity? Or simply to destroy us?"

There were too few clues and too many mysteries. Yvraine felt an unprecedented sense of powerlessness, as if caught in an invisible net.

However, neither Yvraine's confusion nor the Ultramarines' vigilance detected an extremely secretive observer who had already silently infiltrated this Aeldari flagship.

In a dark corner, where light could barely reach, filled with various energy conduits and spirit-bone wiring, a six-eyed raven with eerily blue-black feathers rested quietly. Its six eyes, like six miniature stars containing endless wisdom and malice, each reflected six entirely different scenes:

In the first eye, Yvraine and the Visarch were seen discussing in low voices in the meditation room, their brows tightly furrowed.

In the second eye, Sergeant Golden was seen having an encrypted conversation with Captain Cassius at a communication node, while Dorian's large eagle-faced helmet stubbornly tried to squeeze into the communication range.

The third eye reflected a squad of Ultramarines Terminators patrolling the corridor with heavy steps, their sensors vigilantly scanning the surroundings.

The fourth eye reflected Captain Cassius on the bridge of the Unyielding Will, looking at Dorian as if he were an idiot.

The fifth eye showed Captain Sybils on the Fist of Contrition impatiently urging a technician to complete the post-battle calibration of the weapon systems as quickly as possible.

The last eye showed Calgar complaining to Luna in the resting area about how clumsy and inconvenient the Ironclad Terminator armor was for a sniper.

The raven, an incarnation of the Lord of Change, observed every move of the combined fleet like a silent ghost. Its beak seemed to curl into an extremely human-like, mocking arc.

An extremely subtle whisper, as if acting directly on the depths of the soul, echoed in the shadows, audible only to it:

"The Ynnari... equally foolish. Immersed in so-called salvation and mourning, yet blind to the true danger. Before the great God of Change, all wisdom is so minuscule, all perception can be easily deceived. You... including those self-righteous Grey Knights... will be pushed step by step into the abyss by schemes and trickery. You have long since deviated from the path of destiny, yet you still believe you walk on the right road... Heh heh heh... Next time, what descends... will not merely be an avatar... Heh heh heh heh..."

The laughter was cold and malicious, as if foretelling the arrival of deeper despair.

At the same time, at the communication node of the "Soul Song Blade," Sergeant Golden was focused on his conversation with Captain Cassius, reporting the latest situation on board and the results of his communication with Yvraine.

"...That's roughly the situation, Captain. Yvraine seems to have accepted our explanation and has begun an internal investigation. But there's no further progress yet."

"Very good, continue to monitor, but be mindful of your methods," Captain Cassius's voice came through.

Just then, Dorian's large, helmetless head suddenly squeezed into the communicator's field of view, almost pushing Golden aside.

"Captain! Captain, sir!" Dorian's voice carried undisguised eagerness and a thick-skinned persistence, "You see how dangerous this mission is, and I... I performed pretty well this time, didn't I? Uh... you see... could you... help me talk to the Chapter Master and apply to our Salamanders brothers for a set of that... that 'Saturn-pattern' Terminator armor? Just one set! I promise to fight even harder against the enemy in the future! I definitely won't disgrace our 7th Company!"

Sergeant Golden's heart instantly sank when he heard this, and he inwardly cursed. It's over! Luna shouldn't have said that extra word! This scoundrel was indeed fixated on it! With Dorian's persistent nature, once he knew there was better equipment, if he didn't get it, he would definitely cause a huge commotion. What if the guy suddenly lost his mind one day and secretly went to those Blood Ravens Chapter, whose connections are wild beyond belief, for an 'exchange'... Golden simply couldn't imagine the consequences. The Chapter Master's wrath, fiercer than a Thunderhawk Gunship engine, was something he absolutely did not want to endure!

"Dorian! Get out of here! Is this the time to be talking about this?!" Golden roared in a low voice, trying to push the embarrassing fellow away.

But Dorian was rooted to the spot, not moving an inch, and continued to shout into the communicator: "Captain! Consider it! That thing has thick armor and fierce firepower! I'll definitely be able to take on ten by myself if I wear it! Even those Aeldari will shiver when they see me then!"

Captain Cassius on the other end of the communicator seemed to be momentarily stunned by this sudden 'request,' followed by a helpless sigh.

Seeing that gentle persuasion wouldn't work, Golden had to resort to force. He reached out and grabbed Dorian's ear, pulling him to the side: "Did you hear me! Immediately! Right now! Put on your helmet! Go patrol Sector C! If you say another word, you're getting confined!"

Dorian cried out in pain, yelping and finally, reluctantly, being pushed away from the communicator by Golden.

Watching Dorian grumbling and looking back every three steps as he prepared to leave, Golden, fearing he might cause trouble elsewhere, quickly found another task for him: "Wait! After patrolling Sector C, every half hour... no, every twenty minutes! Go take a look around the command hall, pay attention to what Yvraine and the main Aeldari are doing, and listen if they're discussing anything special. Remember! Just observe! Absolutely no conflict with them! Report any findings to me immediately!"

Finally, having a proper task to do, and satisfying a bit of his curiosity, Dorian was slightly more content. He grumbled, "Got it, Sergeant! I'll make sure to keep an eye on those long-ears!" Then he stomped away with heavy steps, clanking as he went.

Having sent away the annoying Dorian, Golden finally breathed a sigh of relief and awkwardly spoke into the communicator again: "...Sorry, Captain, for making you witness that. Dorian, that guy..."

Captain Cassius on the other end of the communicator, however, did not seem angry. Instead, he pondered for a moment and said: "...Saturn-pattern Terminator armor, you say... A masterpiece of our Salamanders brothers, indeed renowned. It is said that its frontal protection and sustained firepower far exceed our Ironclad-pattern..."

His tone seemed to carry a hint of consideration: "Golden, what do you think... if we could acquire a few sets, or even a batch of Saturn-pattern armor, to equip the 1st Company or squads performing special assault missions, wouldn't it greatly enhance our deterrence and survivability? Especially when dealing with situations that require confronting unpredictable xenos or Chaos forces?"

Golden was surprised that the Captain was actually considering this matter. He paused, then cautiously replied: "...From a purely military perspective, it is indeed extremely powerful equipment. However... Captain, applying to a brother Chapter for such precious special equipment would probably..."

"Hmm, I know it's very difficult," Captain Cassius interrupted him, "but it might be worth suggesting to the Chapter Master. After all, powerful military force itself is the best deterrent, and it also keeps our warriors safer. I will make a note of this and plan it out after this mission is over. For now, let's focus on the task at hand."

"Yes, Captain!" Golden responded, secretly clicking his tongue. He never expected that Dorian's absurd request would actually make the Captain consider it. It seemed the allure of the Saturn-pattern Terminator armor was indeed extraordinary.

The call ended. Golden shook his head, temporarily putting aside the matter of the Terminator armor, and refocused his attention on the monitoring mission. What he didn't know was that the idea of more powerful equipment had already planted a seed in Captain Cassius's mind.

After two days of Warp travel, the combined fleet finally arrived at its destination—the Taranis System.

This sector, like countless similar corners within the Imperium, consisted of several scattered, resource-poor agricultural worlds, a few deep-space mining planets, and Taranis Prime, which served as an administrative and transportation hub.

However, the moment the fleet exited the Warp and entered real space, an extremely unsettling aura, like an invisible tide, washed over them, penetrating even the warships' filtration systems and the power armor's respirators.

It was not a physical smell, but a bizarre "fragrance" that directly affected the soul's perception, cloyingly sweet, like a mixture of rotten honey and stale perfume.

This aura contained the allure of indulgence, extreme sensory stimulation, and the endless void and pain hidden behind pleasure.

Even Astartes, whose wills were as hard as steel, felt a surge of disgust and vigilance upon sensing this aura, instinctively tightening their grip on their weapons.

Slaanesh's corruption had deeply permeated this sector.

Even in the cold void, the defiling mark left by the Chaos God could be clearly perceived.

"All hands, alert! High-intensity Warp contamination detected! Non-combat personnel, minimize psychic perception!" Warnings immediately blared through the broadcasts of all warships.

In the command deck of the Unyielding Will, Yvraine felt the pervasive Slaanesh aura, her delicate face covered in a layer of frost, her eyes filled with undisguised abhorrence and resolve.

This was the Ynnari's mortal enemy, a part of their very reason for existence.

She took a deep breath (though the air was nauseating) and, through the communicator, proactively contacted Captain Cassius of the Unyielding Will and Captain Sibilus of the Fist of Contrition.

"Captain Cassius, Captain Sibilus," her voice came through the communicator, still ethereal, but with an unprecedented solemnity, "You have already sensed the level of contamination in the Taranis Sector.

Although this place is within Imperial territory, confronting Slaanesh is the sacred duty of the Ynnari, and also an opportunity for us to prove our worth and sincerity."

She paused, then made her request: "I request that this purification mission be led and executed by the Ynnari.

The Imperial fleet can hold the line and monitor from the rear.

We will prove to you that the Ynnari's hatred for Slaanesh is no empty boast, and our strength is sufficient for this task."

This request was both bold and reasonable.

Bold because she was actively asking to undertake the primary combat mission within an Imperial sector; reasonable because it was indeed the Ynnari's specialty, and also an opportunity to wash away the shame of their previous mistake and re-prove their worth.

On the bridges of the Unyielding Will and the Fist of Contrition, the two Captains conducted a brief, encrypted consultation.

"What do you think, Sibilus?" Cassius asked.

"Hmph, let them take the lead, it's fine," Sibilus's voice carried her usual impatience, "It saves us the trouble, and we can see what they're truly capable of.

If they mess up again... hmph."

"I agree, but the bottom line and consequences must be made clear," Cassius said in a deep voice.

Soon, communication resumed, and Captain Cassius, on behalf of both of them, responded: "Lady Yvraine, we agree to your request in principle.

The Imperial strike cruisers will establish a defensive line here, monitoring the overall situation.

The Ynnari may proceed with the purification operation as planned."

His tone then became serious, with an undeniable warning: "However, we hope that your side will learn from the previous lesson, act thoroughly, and avoid any more 'accidents'.

Otherwise..."

Cassius's voice grew several degrees colder: "Next time, it won't just be Grey Knights heading to the Unyielding Will.

Captain Sibilus and I will personally pay a visit.

At that time, what we need to discuss will be more than just questioning with a blade at the throat.

Imperial patience and trust cannot withstand a second depletion."

This blatant threat caused Yvraine on the other end of the communicator to fall silent for a moment.

She could clearly feel the weight of his words.

This time, they had no retreat.

"I understand," Yvraine's voice was still calm, but carried a new, heavy determination, "The Ynnari... will not disappoint our allies again.

This battle, only success."

The communication ended.

Yvraine immediately turned to face her kin, issuing a series of concise and clear commands in Aeldari.

The entire Ynnari fleet began to operate like a precise instrument, and the mournful song of death rose again; this time, the song was filled with an air of solemnity and resolve.

Their first chosen target was a small agricultural world on the outermost edge of the system.

According to reconnaissance, the Slaanesh corruption there was most intense, even forming visible, pink-purple miasma that shrouded the planet's surface, clearly one of the main breeding grounds for demonic activity.

Several Aeldari frigates, like arrows shot from a bow, escorted the Unyielding Will towards the contaminated agricultural world.

Two Imperial strike cruisers remained at a relatively safe distance, like silent sentinels, their cold sensors and weapon systems firmly locked onto the target planet and the Aeldari fleet.

Ynnari landing craft rained down onto the planet's surface.

This time, they deployed more elite forces, and their actions were swifter and more decisive.

The battle quickly erupted on the planet's surface.

Through high-altitude reconnaissance and some shared footage transmitted by the Aeldari, the Ultramarines could observe the situation below.

The efficiency of the Ynnari was impressive.

They seemed to have completely learned from the previous lesson, no longer showing any arrogance or underestimation of the enemy.

The Death Jesters moved like dancers of death, weaving through twisted farmlands and corrupted villages, each flash of their kiss blades precisely taking away a Daemonette's "pleasure"; Wraithlords and Wraithguards formed a solid battle line, their massive Soul Song Blades reaping swathes of lesser daemons like wheat; while Aeldari warriors, utilizing their superior mobility and psychic weapons, efficiently cleared scattered daemons and thoroughly corrupted fallen humans.

Their attacks were perfectly coordinated, and their understanding of Slaanesh daemons' weaknesses was extremely precise, especially the attacks imbued with ynnead's death energy, which had a far superior cleansing effect on daemons than Imperial bolters and plasma weapons.

The entire purification process was like a highly efficient surgical operation, precise and lethal.

"These long-ears... they really do have something when it comes to dealing with Slaanesh," Dorian muttered, watching the transmitted combat footage, even he had to admit their professionalism.

Sergeant Golden also nodded slightly.

If it hadn't been for that bizarre Greater Daemon manifestation unexpectedly appearing last time, with the efficiency and targeted approach the Ynnari displayed, they would indeed be more than capable of easily handling a regular Slaanesh incursion.

This made him believe Yvraine's claim about the intelligence being tampered with a bit more.

The battle did not last long.

Under the Ynnari's absolutely counter-effective power and efficient tactics, the Slaanesh daemons and corrupted forces on the planet's surface were cleared with astonishing speed.

The nauseating pink-purple miasma also gradually began to dissipate.

When the last organized demonic force was annihilated, the Ynnari warriors swiftly and orderly withdrew to their landing craft, returning to the fleet.

Their mission was complete; the remaining work did not belong to warriors.

The Unyielding Will slowly approached the planet's orbit.

Yvraine once again came to the bow, gripping the ornate Death Staff with both hands, closing her eyes, and beginning to chant an even older, deeper Aeldari incantation.

A vast power of death gathered again, but this time it was not for attack, but like a gentle tide, or a biting cold wind, slowly sweeping across the entire surface of the planet.

This power did not excessively harm the material world, but it could precisely purify residual Chaos contamination, soothe twisted natural spirits, and gradually free this land from Slaanesh's corruption.

This was a relatively slow process, requiring continuous energy output and precise control.

Yvraine's figure appeared sacred and solemn amidst the psychic glow.

Captain Cassius and Captain Sibilus, observing from the rear, watched everything through their sensors. Seeing the Ynnari's efficient and decisive combat and Yvraine's ongoing purification ritual, their expressions softened slightly.

"It seems... they haven't messed up this time," Sibilus said, a rare comment that wasn't a criticism.

"Hm," Cassius nodded. "Their professionalism in dealing with Slaanesh is undeniable. But this is just the beginning; the situation on Taranis Prime will likely be more complex. Continue to maintain vigilance."

The first battle successfully proved the Ynnari's value and sincerity, temporarily regaining trust. But everyone knew that the real test was yet to come. The path to purification in the Taranis Sector had only just begun. And those raven eyes, hidden in the shadows, observing everything, still gleamed with cold and cunning light.

Yvraine's purification ritual lasted for nearly one standard hour. The light, as cool as moonlight yet imbued with immense death energy, gently and firmly cleansed every inch of the agricultural world's surface. The pinkish-purple corruption miasma, like snow meeting the blazing sun, rapidly melted away in the face of this pure power. The vegetation, twisted and malicious by Slaanesh's fell energies, gradually returned to its original form, and the unsettling stickiness and cloying sweetness on the ground were gradually replaced by a freshness like earth after rain.

This was not simple slaughter, but a deeper form of "cleansing," aimed at fundamentally dispelling Chaos pollution and preventing its resurgence. The entire process was solemn and imbued with a sacred meaning, forcing even the Ultramarines, who held great wariness towards the Aeldari, to admit its uniqueness and effectiveness in combating specific Chaos threats.

When Yvraine finally stopped chanting and the light on her staff gradually dimmed, the agricultural world, though still desolate, had recovered its basic natural balance and no longer emitted that nauseating Chaos aura.

"Purification complete," Yvraine's voice came through the communicator, carrying a hint of fatigue but more of relief. "The primary areas of Slaanesh's corruption on this planet have been cleared. However, a long period of natural recovery is still needed, and I suggest the Imperium dispatch Ecclesiarchy personnel or Inquisition representatives for re-examination to ensure no residual hidden dangers."

"Received. Thank you for your efforts, Lady Yvraine," Captain Cassius's reply was still concise, but his tone was much softer than before. "The fleet will proceed to the next target as planned."

The Ynnari fleet set sail again, heading towards another target within the star system—a small mining world that had reported abnormal energy readings. The two Imperial strike cruisers still maintained their distance, following closely behind.

The subsequent operational pattern became regular. Arriving at the target area, the Ynnari conducted reconnaissance, confirmed the extent of the contamination and the distribution of daemons, then dispatched elite ground forces for efficient extermination, and finally, Yvraine or her designated high-ranking Ynnari Farseer performed a large-scale purification ritual.

The entire process was smooth and efficient. The Ynnari seemed to have thoroughly learned their lesson, always conducting thorough reconnaissance before action, never advancing rashly during combat, and consistently maintaining strict discipline and coordination. Their understanding of Slaanesh daemons and their unparalleled targeted killing efficiency were repeatedly demonstrated before the Ultramarines.

"These bean sprouts, they cut down those flashy daemons faster than mowing grass," Dorian remarked, watching another swiftly concluded battle, unable to help but express his admiration again. He even started to feel that standing around watching the show in his Terminator armor was a bit of a waste of his Thunder Hammer.

Sergeant Gorden, however, paid more attention to details. He noticed that the Ynnari seemed to have corresponding countermeasures and priority kill orders when facing different types and ranks of Slaanesh daemons. The attacks imbued with the power of death inflicted far greater damage on daemons than conventional weapons. This deepened his apprehension about ynnead's power and also made him better understand why the Chapter Master had agreed to this dangerous cooperation—this power, specifically targeting Chaos, especially Slaanesh, indeed held immense value for the Imperium.

However, behind this seemingly smooth purification operation, the invisible shadow had not departed.

In an unknown, dark corner of the "Soul Song Blade," the six-eyed raven still perched quietly. Its six eyes reflected different scenes: Yvraine intently performing the purification ritual, Aeldari warriors efficiently clearing remaining enemies, the cold surveillance of the Imperial warships, and... Gaius, unconsciously caressing the barrel of his "Hawkeye" sniper rifle during a break, an occasional flash of an unnamable complex emotion in his eyes.

The Lord of Change's consciousness, like a cold viper, coiled around the ship. It admired the Ynnari's efficiency, mocked the Imperium's vigilance, and more playfully observed the "pawn" it had chosen.

"Cleaned up so neatly... As expected of the Death God's jackals, always extra diligent when dealing with old rivals," a silent whisper echoed in the shadows. "But what is the meaning of all this? It merely postpones the final feast... The true corruption has already penetrated deep into the bone, how can surface purification eradicate it?"

"Continue to perform... struggle... The harder you try to prove your worth, the more you fall into the web woven by My Lord... When you think you are close to victory, that is when despair truly descends... Heh heh heh..."

Its gaze particularly focused on Gaius. It could sense that deep within the human warrior's soul, the sealed power belonging to the Lord of Change seemed to generate an extremely faint, imperceptible resonance due to continuous proximity to high-intensity Chaos corruption and psychic confrontations. Although Gaius himself might be unaware, this was precisely what Tzeentch desired—gradual influence was the most lethal.

At the same time, on the Unyielding Will, Captain Cassius was also conducting a regular report with the Chapter Master.

"...The situation is roughly as such, Chapter Master. The Ynnari's performance... has been impeccable. Their efficiency in exterminating daemons is extremely high, and the purification rituals are indeed effective. As of now, two outer planets have been successfully purified, with no further unforeseen incidents. Yvraine has also maintained good communication."

Chapter Master Marius Calgar in the holographic projection listened quietly, his fingers gently tapping the armrest of his throne.

"Very good. Continue to maintain surveillance, do not relax your vigilance," he said gravely. "They have proven their worth, but this does not mean the danger has passed. The mastermind capable of tampering with intelligence may still be lurking in the shadows. Has the situation on Taranis Prime been thoroughly investigated?"

"Initial reconnaissance shows that the level of contamination on Taranis Prime far exceeds that of the outer planets, energy readings are extremely abnormal, and... there appear to be a large number of trapped civilians," Cassius's tone became solemn. "That place... is very likely the core of Slaanesh's power. The Ynnari also stated that the purification of the main world will be a tough battle."

"As expected," Calgar's eyes were sharp. "Inform Sibilus to make all battle preparations. Should the Ynnari's assault falter, or any anomaly occur, the Imperial fleet must be ready at any moment to provide the strongest fire support, or even direct intervention. Our bottom line is that Slaanesh must not be allowed to gain a foothold on the main world, nor can we tolerate large-scale civilian casualties becoming sacrifices to Chaos."

"Understood, Chapter Master!"

The call ended. Cassius knew that the earlier smoothness was merely a prelude; the real test—Taranis Prime—was imminent. What was hidden there was the true face of this crisis. The combined fleet once again adjusted its course, heading towards the center of the star system, the main world already shrouded in unholy light. Beneath the calm, undercurrents surged, and a greater storm awaited them ahead.

The combined fleet hovered in orbit around Taranis Prime, like predators circling their prey, gazing at the utterly defiled planet below.

Unlike the outer planets, the main planet's atmosphere seemed permanently stained with an ominous, shifting pinkish-purple glow; even from space, one could feel the almost solidified Chaos energy, a mix of extreme pleasure and pain.

Twisted spires and blasphemous statues pierced through the clouds like cancerous growths, vaguely visible.

According to intelligence compiled from multiple reconnaissance missions and psychic probes by the Ynnari, Taranis Prime was not only the most severely corrupted area by Slaanesh, but also harbored at least one powerful Greater Daemon of Slaanesh avatar deep within it, serving as the energy core and command center of this fallen land.

Facing such a formidable enemy, the Ynnari dared not show any slack.

They made thorough pre-battle preparations; ancient Aeldari devices specifically designed to combat powerful Daemons—matrix generators known as "Void Cages"—were carefully deployed on several frigates.

These devices could generate powerful spatial containment fields and psychic interference, specifically used to trap and weaken Greater Daemon-level entities, creating an opportunity for their eventual purification.

At the same time, a practical problem arose: there were still many Imperial civilians on the main planet who had not been evacuated or had been corrupted by Chaos.

The Ultramarines would never stand by and watch them become fodder for Daemons or sacrifices for Chaos.

On the bridge of the Unyielding Will, Captain Cassius issued his orders: "The Ynnari will lead the main assault, clearing out the primary Daemon forces and attempting to trap or even destroy that Greater Daemon avatar.

Once the main areas are controlled, the 7th Company will immediately dispatch rescue squads to pre-designated locations where survivors might be gathered, to rescue as many civilians as possible."

He paused, then added with a heavy tone: "But the prerequisite is that the Ynnari must first open a path and ensure the landing zones are relatively safe.

We cannot let our Space Marines jump blindly into a Daemon encirclement."

Just then, aboard the "Soul Song Blade," Gaius, who was waiting in his Terminator armor, suddenly felt an extremely faint yet incredibly clear tremor deep within his left arm.

It was a familiar, yet deeply unsettling warmth, as if something long dormant was being stimulated by powerful, homologous energy from outside, slowly awakening.

It was the power of the Lord of Change!

It seemed to resonate and connect ever so faintly with some deeper, well-hidden energy emanating from the main planet below.

The sensation was fleeting, but it made Gaius's heart sink.

He vaguely realized that the problem on Taranis Prime was probably far more complex than just a Greater Daemon of Slaanesh avatar.

Beneath the dense Slaanesh corruption, something else, far more cunning and unpredictable, seemed to be hidden.

Just then, Sergeant Golden's communicator chimed, relaying a direct order from Captain Cassius:

"Sergeant Golden, Second Squad, attention!"

"Sir! Captain!"

"Your squad, as one of the 7th Company's most elite, has a change in mission.

After the Ynnari launch their attack and initially clear the landing zones, your squad will embark on the Thunderhawk Gunship 'Storm' and land near the entrance to the Third Refuge in Obsidian City on the main planet.

According to the last valid pre-battle communication record, a large number of civilians may be trapped there.

Your mission is to rescue as many survivors as possible and escort them to the evacuation point."

"Coordinates and data packets will be sent to you shortly.

Another squad will temporarily take over your surveillance duties on the 'Soul Song Blade.'"

Captain Cassius's tone became particularly serious, "Remember, Golden, the situation on the main planet is far more complex than anticipated, so be extremely careful.

Prioritize squad safety and mission completion; if faced with insurmountable odds, you are authorized to abandon the mission and withdraw."

"Understood! Captain! Second Squad guarantees mission completion!" Golden responded in a deep voice.

With the order given, Second Squad immediately sprang into action.

Gaius finally breathed a sigh of relief; he could finally shed this Ironclad Pattern Terminator armor that made him feel so uncomfortable.

Compared to the Terminator's unparalleled protection and firepower, he preferred the flexibility and stealth offered by standard power armor, which was more suited to his sniper combat style.

He quickly changed back into his familiar Mark X power armor, painted in the 7th Company's standard blue with numerous subtle battle scars, and slung his "Hawkeye" sniper rifle back over his shoulder, feeling much more agile.

Sergeant Golden and Dorian, however, continued to wear their Terminator armor.

Golden, as the squad commander and assault core, needed the Terminator's protection and fire support capabilities; Dorian, furthermore, couldn't part with his newly repaired "old friend," and as an assaulter, he would be the primary force for charging into battle and clearing obstacles.

After careful treatment by the Aeldari medic and a period of recuperation, Dorian's injuries had almost completely healed, and the over-energetic, boisterous, and occasionally troublesome Dorian was back.

Upon learning that there was finally a real combat mission instead of just standing guard, he excitedly slapped his chest plate, making a clanging sound:

"Haha! Finally, I can stretch my muscles!

I'm sick of watching those long-ears perform!

This time, watch how I use my Thunder Hammer to smash those flamboyant Daemons into pancakes!"

Golden shot him an exasperated look: "Quiet down!

This mission is about rescuing civilians, not for you to run wild!

Follow all orders; if you dare to act on your own again, when we get back, I'll request to have you transferred to the kitchen to peel potatoes!"

Dorian shrank his neck, giving an embarrassed smile, but the excitement in his eyes remained undiminished.

An hour later, the Ynnari's general assault began.

As before, the Aeldari fleet initiated the attack, with dense psychic beams and precise artillery fire surgically clearing scattered orbital resistance and large blasphemous ground structures.

Immediately following, a swarm of landing craft and drop platforms descended upon the main planet's surface like bees.

The battle escalated to a fever pitch from the very beginning.

The number and quality of Slaanesh Daemons on the main planet far surpassed those on the outer planets, with many powerful Keeper of Secrets direct subordinates even appearing.

However, the well-prepared Ynnari displayed astonishing combat prowess.

Their tactics were clear, their coordination exquisite, and by exploiting their advantages against Daemons and the pre-deployed "Void Cages," they steadily compressed the Daemons' operational space, pushing towards the designated core area.

The 7th Company's three Thunderhawk Gunships also took off from the Unyielding Will, like three poised falcons, circling the edge of the battlefield, awaiting the opportune moment to land.

One of them was the "Storm," carrying Golden's Second Squad.

Meanwhile, deep within Obsidian City, shrouded in dense Chaos energy, inside a palace of twisted crystals and blasphemous metal that echoed with eerie melodies, the Lord of Change—Kairos Fateweaver—slowly revealed its true form.

It was not a Keeper of Secrets of Slaanesh, but a powerful Daemon Prince belonging to Tzeentch, the Lord of Change.

Its distinctive two-headed form—one head gazing into the past, the other peering into the future—exuded an aura of infinite cunning and knowledge.

It was hidden behind the dense Slaanesh energy, like the most brilliant conspirator, lurking behind the scenes of the stage.

On its future-gazing head, a malicious smile played on its lips, as if it had already seen the predetermined fate.

It whispered, its voice like the friction of countless fragments of knowledge:

"Come... come... Chosen of the Gods... follow the predestined path... step onto this stage meticulously prepared for you... your destiny... has long been written..."

It was waiting, waiting for that crucial piece to fall into this meticulously woven web.

The chaos on Taranis Prime was merely the overture to its grand symphony.

The true conspiracy was only now quietly unfolding... The chaos on Taranis Prime was merely a smokescreen it had ignited to achieve a deeper purpose.

The true stage was quietly being built amidst the ruins of this planet.

The Ynnari's general assault unfolded on the defiled surface of Taranis Prime like a precise and deadly dance.

Aeldari landing craft descended like silver raindrops, accurately touching down at predetermined tactical nodes.

Upon landing, the agile Ynnari warriors scattered like phantoms, their Kiss Blades carving cold trajectories under the eerie pinkish-purple sky, each flash accompanied by the short, piercing shriek of a Slaanesh Daemonette.

Wraithlords strode with heavy steps, their massive Wraith Scythes sweeping, conjuring whirlwinds of death that sliced charging swarms of Plague Flies and twisted Keeper of Secrets degenerates into shattered energy dust.

Yvraine commanded from the "Soul Song Blade," her will like invisible threads guiding the entire battle.

The psychic matrix's light flowed between the fleet, continuously strengthening the ground forces while suppressing the spread of Slaanesh's energy.

The deployed "Void Cage" generators began to hum, and invisible spatial containment fields spread like a net over the most concentrated Daemon areas, especially the core that continuously emitted heart-pounding fluctuations—the blasphemous Palace of Pleasure in the center of Obsidian City.

Deep within the palace, the powerful Greater Daemon of Slaanesh avatar was finally enraged and revealed itself.

Its massive and twisted body was composed of smooth chitin, shimmering mother-of-pearl, and constantly writhing pink flesh, with countless tentacles covered in suckers lashing the air like frenzied pythons, emitting mind-shattering sonic booms.

Its androgynous face, filled with ultimate temptation and cruelty, was contorted in outraged fury.

"Wretched Aeldari scum! How dare you disturb the eternal feast!" it roared, powerful Warp energy shockwaves spreading out like a tsunami, instantly cracking the spirit-bone bodies of several Wraithguards who had charged too far ahead.

However, the Ynnari were well-prepared for this.

Several high-ranking Ynnari Farseers chanted in unison, and the powerful death energy of ynnead coalesced into a grey-white aura, forcefully withstanding the Warp energy impact.

At the same time, the "Void Cages" activated at full power!

Several pale energy beams descended from the sky like giant shackles, firmly wrapping around the Keeper of Secrets avatar's body, greatly restricting its movement and power output.

"Now! For ynnead!" a Ynnari commander shouted.

More Aeldari warriors surged forward like a tide, surrounding the furiously struggling Greater Daemon avatar.

Kiss Blades, Wraith Scythes, and psychic spears rained down upon it like a Storm, each attack taking a part of its physical form and energy.

Attacks imbued with the divine power of death were particularly effective, continuously purifying its defiled essence.

This was a difficult and brutal war of attrition.

Aeldari warriors constantly fell to the Keeper of Secrets' frantic tentacle lashes and Warp energy blasts, transforming into shattered spirit-bones and dissipating souls.

But the Ynnari's line held firm, their attacks precise and efficient, and combined with the continuous weakening from the "Void Cages," the Keeper of Secrets avatar's power was visibly diminishing.

Finally, with a Wraithlord sacrificing half of its body to lock its core tightly with a massive scythe, and a focused beam of death energy guided by Yvraine from orbit, the colossal Greater Daemon of Slaanesh avatar let out a final, unwilling shriek.

Its massive body disintegrated like shattered glass, turning into a sky full of flying ashes and gradually dissipating Warp energy.

The threat at the palace's core was temporarily cleared.

Almost simultaneously with the destruction of the Greater Daemon of Slaanesh avatar, Captain Cassius on the Unyielding Will received a message from the Ynnari: "Primary threat cleared, the path to the Third Sanctuary has been initially secured, but the area remains unstable. Please act swiftly!"

"7th Company, rescue squad, deploy immediately!" Captain Cassius gave the order without hesitation.

The engines of three Thunderhawk Gunships roared, like three blue meteors, breaking through the thin and polluted atmosphere, speeding towards the coordinates of the Third Sanctuary in Obsidian City.

Inside the Storm, Sergeant Golden checked his equipment one last time: "Final equipment status check! Remember the mission objective: rescue civilians, priority evacuation! Do not engage in unnecessary combat! Dorian, especially you, hold back a bit, don't smash down the sanctuary entrance!"

"Don't worry, Sergeant! I know what I'm doing!" Dorian assured, patting his chest plate, his Power Fist humming with stored energy, clearly eager to go.

Gaius took a deep breath, trying to suppress the unease caused by the faint throbbing in his left arm, and focused completely on the upcoming mission. He adjusted the strap of his "Eagle Eye" to ensure it was readily accessible.

Luna silently checked her servo-arm and various detection equipment; she was the squad's information hub and technical support.

The Thunderhawk Gunship jolted violently, penetrating the smoke and dust shrouding the city, finally coming to an abrupt halt, hovering steadily before the massive, but now severely deformed and graffiti-covered metal gate of the Third Sanctuary.

The hatch burst open!

"Go!"

Golden was the first to rush out, the heavy footsteps of his Terminator armor crashing on the broken flagstones. Dorian followed closely like a human tank, his Thunder Hammer already active, crackling dangerously. Gaius and Luna quickly took cover positions on either side of the gate. Gaius raised his Bolter, scanning the surroundings, while Luna began to use her tools to try and bypass the gate's control panel.

The area around the sanctuary was eerily silent, with only distant explosions and faint daemon howls. The air was thick with the smell of blood, ash, and the sickly sweet scent of Slaanesh, making it nauseating.

"The gate is partially locked from the inside, and there's physical damage to the latches!" Luna reported quickly, "It will take time to bypass, or... we can force it open!"

"No time! Dorian!" Golden ordered immediately.

"I've been waiting for this!" Dorian roared, stepping forward, his massive Thunder Hammer, imbued with immense force, slammed violently into the sanctuary gate's hinges!

Boom!!!!!!

A deafening roar echoed through the ruins, the sound of metal twisting and tearing was grating. The heavy blast door was forcibly dented inwards, creating a huge gap.

"Enough! Advance!" Golden squeezed through the gap first, the light from his Bolter's muzzle piercing the darkness within.

The situation inside the sanctuary was dire. Bodies were everywhere, some killed by daemons, others appearing to have taken their own lives in extreme ecstasy or agony, their faces frozen in eerie expressions. Survivors huddled in corners, their eyes vacant, filled with fear and numbness. Seeing the fully armed Astartes appear, they first let out terrified screams, until they recognized the azure armor and the Imperial Aquila, which then turned into cries of relief and pleas for help.

"We are Ultramarines! Sent to rescue you! Those who can still move, gather at the entrance immediately! Hurry!" Golden roared through his vox-caster, his voice echoing in the vast sanctuary space.

Gaius and Luna were responsible for guarding the deeper passages, while Dorian, with his massive physique and intimidating presence, maintained order, helping the weak civilians to their feet. Golden quickly counted the numbers; there were nearly a hundred survivors, more than he had anticipated, making evacuation difficult.

Just as the rescue operation was underway, and the first batch of civilians began boarding another Thunderhawk under the guidance of the Battle Brothers waiting outside—

A sudden change occurred!

From the depths of the sanctuary, in the dark corridor that was thought to be cleared, several pairs of cold, glowing witch-light eye lenses suddenly lit up! Immediately after, heavy footsteps of Power Armor, bearing clear signs of Warp corruption, echoed.

Five giants in blue Power Armor slowly emerged from the shadows, blocking the passage to the deeper areas, and cutting off a part of Sergeant Golden's squad's retreat route.

Their armor was an ominous, deep blue, as if scorched by sorcerous flames, adorned with numerous intricate and blasphemous runes, twisted metallic tendrils, and the symbol of the Chaos Eight-Pointed Star. Their helmets were strangely shaped, some resembling a hybrid of bird and daemon, others covered in prophetic inscriptions. Their weapons were wreathed in unceasing sorcerous flames, and their bodies exuded strong psychic fluctuations and an oppressive aura of arrogance and madness that suppressed the mind.

They were Thousand Sons! The Chaos Space Marines of Tzeentch!

Leading them was a sorcerer wielding a staff inlaid with a large blue gemstone, burning with a ghostly blue flame. His armor was more ornate, with strange patterns foretelling fate carved on his shoulder pads, and horns on his helmet like twisted star trajectories.

"Ah... look who it is?" The leading Thousand Sons sorcerer uttered a mocking voice, metallic and resonating with psychic power, "The False Emperor's lackeys, leaving your... hypocritical Five Hundred Worlds, to come to this filthy... place to save these mortals?"

His gaze swept over the panicked civilians, finally settling on Golden and the others, filled with undisguised malice and a condescending "pity."

"Truly... a touching scene. Unfortunately, these souls... and yours... are already destined." He raised his staff, and the ghostly blue flames began to burn fiercely, "For the Lord of Change! Leave them!"

The other four Thousand Sons warriors simultaneously raised their twisted, blue-glowing Bolters.

"Chaos scum!" Golden roared, instantly raising his Bolter and firing! "Open fire! Protect the civilians!"

The roar of Bolters instantly shattered the brief calm within the sanctuary! Second Squad reacted extremely quickly, immediately taking cover and returning fire. Dorian roared, pushing to the front, his Terminator's heavy armor shrugging off several Chaos Bolter rounds, sparking. He then slammed his Thunder Hammer into the ground, the resulting shockwave temporarily hindering the enemy's advance.

Gaius quickly retreated, looking for a sniping position. His "Eagle Eye" sniper rifle let out a muffled roar, and a Bolter round accurately struck a Thousand Sons warrior's shoulder pad, making him stumble, but it was not fatal, as the flickering sorcerous shield on his armor absorbed most of the damage.

Luna quickly released a small reconnaissance servo-skull, while also attempting to jam the enemy's communications and psychic channeling.

The battle erupted instantly! Chaos Bolter rounds and loyalist Bolter rounds crisscrossed in the air, psychic lightning and servo-arm plasma cutting beams collided, creating dazzling energy sparks. The Thousand Sons were not only fierce in their firepower but also cunning in their tactics, constantly using psychic powers to create illusions and shields, attempting to divide and surround Second Squad.

"For Macragge!" Dorian roared, charging forward through the gunfire, attempting to suppress the sorcerer in close combat. But a Thousand Sons warrior, wielding a Power Sword wreathed in blue flames, blocked him. Their weapons clashed violently, erupting in a deafening crash and energy shockwave.

Golden calmly directed the fight, suppressing other enemies with his Bolter and grenade launcher. "Gaius! Prioritize killing that sorcerer!"

Gaius held his breath, the crosshairs of his "Eagle Eye" locked firmly on the head of the Thousand Sons sorcerer who was channeling powerful sorcery. However, just as he pulled the trigger, the sorcerer, as if prescient, tilted his head slightly. The Bolter round grazed his helmet, leaving only a scorch mark! The sorcerer's cold gaze instantly turned towards Gaius's direction, and with a wave of his staff, a space-distorting psychic blast hurtled towards Gaius's hiding place!

Gaius stumbled to the ground in a desperate dive, the pillar he was hiding behind exploding into dust!

"Tsk! These damn sorcerers!" Gaius cursed under his breath, quickly relocating.

The battle fell into a stalemate. Although the Thousand Sons were few in number, their individual strength was formidable, and their sorcery was bizarre. Second Squad found it difficult to break through their interception, and the evacuation was severely delayed.

Just as Golden was considering whether to call for orbital support—

The entire sanctuary, no, the space of the entire area, suddenly became stagnant! An incredibly vast, ancient will, filled with endless wisdom and cold malice, suddenly descended!

The sound of gunfire seemed to be choked off by an invisible hand, and even the dust dancing in the air seemed to halt.

From the deepest part of the sanctuary, from the most intense shadows that even the Thousand Sons dared not approach, a figure slowly emerged.

It was extremely tall, even surpassing Dorian in his Terminator armor. Its form was extraordinarily bizarre—it possessed two heads. The eyes on one head gazed into the past, with countless fragments of history flowing within them; the eyes on the other head peered into the future, with thousands of possible fate lines flickering within them. Its body was covered in ancient, deep blue armor, adorned with profound runes and stellar trajectories, these runes seemingly alive, constantly flowing and changing. Its limbs were long and slender, and it held no obvious weapon in its hands, but the almost suffocating psychic pressure it exuded was, in itself, the most terrifying weapon.

Its appearance caused all the Thousand Sons to immediately cease their attack, bowing their heads in immense reverence, even with fear.

Golden felt his breathing almost stop, his gene-seed trembling with instinctive warning. He recognized this entity, from the Chapter's forbidden archives—

Kairos Fateweaver! The Lord of Change! One of the most powerful and cunning Daemon Princes under Tzeentch!

Kairos's two heads turned simultaneously, the gazes of past and future intertwining, falling upon... Gaius. That gaze was filled with amusement, scrutiny, and a satisfaction as if seeing a predetermined prey fall into a trap.

A voice resounded directly in everyone's minds, not transmitted through the air, but imprinted directly into their consciousness. It was a mix of countless tones, at times like a wise man's whisper, at times like a mad howl:

"The threads of fate... finally converge here..."

"I have waited long... Chosen of the Gods..."

"Your journey... your confusion... the power slumbering in your arm... all are for this moment... for... an audience with my Lord..."

"Welcome to... the true proving ground..."
