The Shattered Walkway was not merely a passage; it was a physical ledger of everything that guarded it. Leylin read the story written into the stone as the strike force moved into their approach vectors.
The structural failure was not random or aged by mere millennia. The deep, spiderwebbing fractures were organized around specific, recurring stress points—the exact places where Kologarn's colossal stone fists had slammed into the masonry over uncounted ages.
The walkway remembered every crushing blow, every intruder ground to dust against its surface. He filed the geometry away, converting spatial context into immediate, cold tactical data.
Across the chasm, the thirty-second window was rapidly shrinking to twenty.
"The arms are independent targets," Leylin said, his voice flat, low, and stripped of unnecessary prose. He didn't look back as the officers adjusted their grips on their weapons; his eyes remained locked on the dormant titan giant. "Priority one is the Right Arm. It drives the Stone Grip. If a soldier is scooped up, destroying that arm is the only method of release. You do not try to pry the fingers open. You shatter the arm. The person trapped inside cannot survive any other way."
He shifted his focus slightly toward the heavy frontline—Muradin Bronzebeard, Vindicator Yaala, the hardened Horde vanguard, and the paladins of the Argent Crusade.
"Arm suppression requires immediate, explosive physical force," Leylin continued. "Assign your strike team now, before the grip closes."
Muradin didn't waste words. He thrust a blunt, gauntleted finger at four heavily armored Argent Crusade veterans. They offered single, sharp nods—professionals receiving an execution order they understood completely.
"Next: the Rubble," Leylin said, his voice cutting through the rising wind of the abyss. "When an arm is destroyed, its shattered remains will animate into stone constructs. They cast Rumble—a localized, high-density seismic aura that tears apart anyone in immediate proximity. The Ninjakhan will intercept the Rubble the second it forms. Everyone else maintains maximum engagement distance from the arm's destruction site until the adds are cleared."
High above, melted into the shadows of the broken vaulted ceiling, the nine remaining Ninjakhan acknowledged the command through the peripheral pulse of their shared bond. They were positioned, silent, and waiting.
"Then there is the Focused Eyebeam," Leylin warned. "It targets a single mind at random and follows them relentlessly. If the beam locks onto you, you run. If you are not the target, you clear the path between Kologarn and the runner immediately. The beam does not stop for allies. If you stand in its line of sight and you aren't the target, you are choosing to die. Remove yourselves from the path before the energy reaches you."
Ten seconds.
"Tanks, watch the Crunch Armor stacks," Leylin added, glancing toward Yaala. "The physical degradation accumulates exponentially. You rotate before the armor's integrity fails. Yaala, you call the swap."
"I'll call it," Yaala said softly, her massive broadsword already resting across her shoulder, its holy crystal pulsing with a quiet, steady radiance.
Five seconds.
Leylin looked across the void.
Kologarn remained still—a gargantuan statue carved from the bedrock of the world, his massive chest spanning the entire width of the bridge, his lower half anchored deep into the darkness of the chasm below.
Leylin stepped over the threshold and onto the shattered bridge.
At the walkway's first third, Kologarn's sensory perimeter tripped.
The activation was not the instantaneous, lightning-fast snap of the Assembly of Iron. It carried the massive, ponderous momentum of something so immense that its very perception operated on a different scale of time. The titan giant's massive, carved head turned slowly, the heavy grinding of ancient stone echoing through the cavern like a localized earthquake.
His eyes—carved spheres of Titan-forged granite, long since infused with the sickly, pulsing yellow veins of Yogg-Saron's corruption—pivoted down to focus on the mortals crossing his span.
Then, Kologarn moved.
The motion of an entity his size possessed a terrifying, paradoxical quality: it appeared slow because of the sheer distance his limbs had to travel, yet it achieved terrifying speed because a single sweep of his arm covered eighty feet of space in a fraction of a second. His massive right stone hand came down toward the leading edge of the walkway with practiced, devastating precision—a motion he had executed ten thousand times against ten thousand intruders.
"Spread and engage!" Leylin commanded.
The strike force fanned out across the available width of the bridge with fluid, rehearsed discipline. The tight marching formation instantly dissolved into a wide, staggered grid designed to minimize the impact of wide-area sweeps.
Leylin raised his hands, unleashing a targeted stream of black-tinged fire directly into Kologarn's massive stone torso. He avoided the arms for now; the initial phase demanded sustained, steady pressure on the core body while the specialized strike team monitored the right limb. The flames organized around the giant's chest, probing for the subtle thermal faults in the Titan-forged stone.
Simultaneously, a blinding lance of pure arcane energy slammed into Kologarn's left shoulder from the elevated masonry on the left flank. High Mage Rhonin had taken the ledge—a precarious, exposed position over the abyss, chosen because it offered an unobstructed line of sight. On the opposite flank, Jaina Proudmoore took the matching ledge, her staff weaving a continuous frost-mesh that chilled the giant's joints.
The two Archmages, separated by the full width of the chasm, anchored the Kirin Tor's casting grid with symmetric, terrifying efficiency.
Two minutes into the engagement, the first Stone Grip descended.
Leylin felt the spatial shift through his sensory network a split-second before the visual confirmation. The biological and magical matrix of Kologarn's right arm flared as the massive stone fingers swept across the bridge floor, scooping up a five-yard section of the formation in a single, irresistible crush.
The giant's fist snapped shut around three soldiers—a Horde frontline warrior, an Argent paladin, and a Kirin Tor battle-mage.
In the elevated difficulty of Ulduar's inner ring, the Stone Grip was not a slow pressure test; it was a lethal compactor. The crushing force increased exponentially with every tick of the clock, the stone fingers grinding armor into scrap and flesh into pulp.
"Right arm! Now!" Vindicator Yaala roared, her voice ringing across the cavern.
Muradin and his four designated Argent Crusade veterans struck the giant's right limb in perfect unison. There was no sequential wind-up, no hesitation. Heavy warhammers, holy-infused battleaxes, and crushing mace-strikes slammed into the stone elbow joint at the exact same instant.
The Titan-forged granite absorbed the physical trauma with stubborn resilience, small chips of stone flying off, but the structural integrity held.
"Hold the angle!" Leylin called out, thrusting his hands forward.
He channeled a focused beam of intense, superheated fire directly onto the fracture point Muradin's hammer had created. Applying his deep understanding of mineral structure and thermal expansion, Leylin concentrated the extreme heat onto the exact molecular fault-line where physical impact met thermal stress.
CRACK.
A sound like a thunderclap echoed off the cavern walls as a massive, jagged fissure split the right arm from wrist to shoulder.
The entire limb fractured and broke apart. The giant's hand lost its grip, disintegrating into falling boulders, and the three trapped soldiers tumbled onto the stone bridge. Before they even hit the ground, Lady Liadrin's area-healing wards enveloped them, knitting broken ribs and shattered plate armor the moment their boots touched the floor.
As the shattered arm crashed onto the walkway, the broken stone writhed and reassembled into three towering, aggressive Earth Rubble elementals.
Before the constructs could channel their devastating Rumble aura, shadows detached from the ceiling.
The Ninjakhan dropped from the darkness, their shadow-blades flashing in synchronized strikes. They engaged the Rubble instantly, drawing the elementals away from the main force and pinning them against the outer ledge before the seismic pulses could disrupt the healers.
Suddenly, a blinding, crackling hum filled the air.
Kologarn's massive eyes flared with violent, concentrated arc-energy. A twin beam of scorching, yellow light erupted from his pupils, locking directly onto Alleria Windrunner.
Focused Eyebeam.
Alleria was already moving. Her ranger instincts had picked up the subtle atmospheric shift a fraction of a second before the energy discharged. She pivoted on her heel and sprinted down the left side of the walkway, the twin lances of destructive energy tearing through the stone floor mere inches behind her boots.
"Clear the line!" Leylin barked.
The strike force parted like the sea, clearing a wide, empty corridor along Alleria's escape path.
Almost everyone cleared the line.
Brann Bronzebeard was currently scrambling across the center lane, his eyes glued to the regenerating stump of Kologarn's right arm, completely oblivious to the sweeping beam of death heading his way.
"Brann, move your scrawny dwarf arse!" Muradin bellowed.
Brann snapped out of his academic haze, saw the twin beams of disintegrating light searing toward his face, and executed a desperate, surprisingly nimble dive-roll over a fallen pillar.
The Focused Eyebeam passed through the exact space Brann's head had occupied half a second prior, carving a glowing, molten trench into the ancient bridge.
Muradin didn't even break his stance, merely offering a weary, exasperated grunt as Brann scrambled to his feet, sheepishly checking if his beard was singed.
At the far edge of the walkway, Alleria reached the terminal stone wall. Without slowing down, she planted her boot against the masonry, vaulted backward over the incoming beam, and landed gracefully twenty feet away. Deprived of its target, the Focused Eyebeam slammed into the outer wall and dissipated harmlessly into a cloud of stone dust.
Meanwhile, Kologarn's right arm had already begun its rapid regeneration cycle.
Leylin's tactical network tracked the rapid regrowth of stone. In the inner sanctuary's accelerated state, the arm was restoring its structural density at twice the normal rate. This forced the commanders to constantly recalculate their damage output—dividing their fire between Kologarn's primary torso, the regenerating right arm, and the looming threat of the left arm.
"Maintain primary focus on the chest!" Leylin ordered, adjusting his spell vectors. "Arm team holds reserves until the next grip engages!"
Thrall stood near the center span, his heavy boots locked onto the cracked tiles. The Horde Warchief held his hands high, calling upon the deeply disturbed earth spirits of the mountain. Despite the heavy, suffocating distortion of Yogg-Saron's presence, Thrall tapped into the deep, uncorrupted bedrock far below the complex, launching massive, elemental earth-shocks into Kologarn's exposed chest core.
Harbinger Vurenn glided through the ranks like a ghost, his glowing blue eyes scanning the minds of every caster, warrior, and ranger.
Old Gods did not merely attack through physical force; they used moments of intense combat stress—when a soldier's focus narrowed down to raw survival—to slip subtle, corrupting whispers into the subconscious.
Vurenn stopped briefly beside Tyr'ganal, who was weaving counter-curses against Kologarn's ambient aura.
"Tyr'ganal," Vurenn said softly, his voice a calm, reassuring anchor amidst the chaos.
Tyr'ganal's eyes flickered, his focus sharpening instantly. "Harbinger?"
"A shadow-line attempted to anchor into your arcane sensitivity three seconds ago," Vurenn reported calmly. "It sought a foothold while your concentration was divided." The old draenei looked at him intently. "It failed. You recognized it."
"I felt a sudden, cold distortion in the ley-line," Tyr'ganal admitted, wiping sweat from his brow. "I severed the connection immediately."
"Good," Vurenn approved with a gentle nod. "Keep your inner eyes open. The dark does not knock; it slips through open cracks."
At the seven-minute mark, the physical strain on the frontline reached a critical threshold.
Kologarn's heavy, crushing blows had applied five stacks of Crunch Armor to Vindicator Yaala. Her heavy plate armor was warped and cracked, the divine wards surrounding her flickering under the immense physical degradation.
"Rotation!" Yaala called out, her voice crisp and devoid of panic. "Swap now!"
Muradin immediately stepped forward, raising his heavy tower shield to intercept Kologarn's massive left fist as Yaala disengaged, pulling back so Lady Liadrin could cleanse the lingering physical debuffs from her armor.
Precisely as the tanks swapped positions, Kologarn's left arm swept forward in a second, sudden Stone Grip.
The timing was atrocious—a brutal overlap of mechanics designed to test the army's coordination to its absolute limit. The stone fingers clamped down over the center lane, trapping two Argent Crusade paladins and High Mage Rhonin.
"Right arm! Break it!" Yaala shouted, instantly stepping back into the fight despite her battered armor.
The suppression team re-engaged the right limb with terrifying ferocity. Leylin unleashed a continuous torrent of focused thermal energy, targeting the newly formed stone seams of the regenerated arm. Muradin, Yaala, and the Argent Crusade veterans hammered the limb with everything they had left.
The stone groaned, fractured, and violently exploded into a shower of rubble.
The left hand opened, dropping Rhonin and the paladins onto the bridge, where Jaina's instant ice-shields caught them before they could hit the stone hard.
With both arms shattered and his regenerating capacitors drained, Kologarn's chest core lay completely exposed.
"All forces, execute final burn!" Leylin bellowed, his voice echoing over the thunder of the collapse.
Every archer, battle-mage, shaman, and warrior unleashed their remaining reserves. A catastrophic avalanche of arcane missiles, holy fire, shadow arrows, and elemental lightning slammed directly into the glowing, corrupted core in Kologarn's chest.
The giant titan let out a sound that shook the entire mountain—a long, agonizing groan of rending, failing stone.
Cracks of blinding, white-hot energy spider-webbed across his colossal torso. The ancient Titan-forged machinery driving his heart surged uncontrollably, overloaded by the relentless, focused trauma.
Kologarn's massive stone arms collapsed into the abyss below. Then, with a slow, sweeping crash that shattered the remaining center tiles of the walkway, the giant's massive upper torso toppled forward, slamming face-down into the chasm, his body forming a permanent, stone bridge across the broken gap.
Then, silence returned.
The heavy, suffocating roar of combat vanished, replaced only by the quiet whistling of the icy wind blowing up from the dark depths below.
The strike force stood frozen, catching their breath. The frontline was battered, armor scorched and dented, but every single soldier was still standing.
Harbinger Vurenn walked slowly down the line, touching his glowing hand to the brows of the soldiers as he completed his post-battle audit.
"Clean," Vurenn announced softly, moving past the Kirin Tor mages. "Clean... clean..."
He stopped before Brann Bronzebeard, staring at the dwarf for a long, silent moment.
Brann cleared his throat, shifting his boots. "Alright, old mystic, what is it this time? I didn't get hit by the beam."
"You did not get hit by the beam," Vurenn agreed patiently. "Yet your mind lingers on how close the energy came to your face. You are feeding on the near-miss."
Brann blinked. "Well, it was close!"
"The corruption does not merely feed on terror, Master Bronzebeard," Vurenn explained, his glowing eyes holding ancient wisdom. "It feeds on morbid fascination. It uses the thrill of narrowly escaping death to slip past your spiritual guards."
Brann looked down at his boots, then over at Muradin, who was leaning on his hammer, silently shaking his head with an expression that said I've been telling you that for two hundred years.
"Right," Brann muttered softly. "Focus on the objective. Less admiring the danger."
Beyond the fallen form of Kologarn, through the colossal archway he had guarded for ten millennia, lay the entrance to the Inner Sanctum of Ulduar.
The atmosphere shifted instantly.
The air here was no longer just cold or corrupted; it was thick, heavy, and saturated with an ancient, terrifying intellect. The ambient, unfocused madness of the outer halls gave way to a sharp, singular, and deeply personal awareness.
They were no longer just fighting the fortress's automated defenses. They had stepped into the room with the prisoner itself.
Harbinger Vurenn stopped at the edge of the new threshold, his glowing blue eyes darkening as he looked into the deep, shadowy corridor ahead.
"The core," Vurenn whispered, his voice carrying a rare, chilling weight.
"Yes," Leylin said softly, stepping up beside him.
"It is entirely awake," Vurenn reported, his tendrils twitching slightly. "Everything we have done—every construct we have dismantled, every guardian we have slain—has been registered and calculated. What lies ahead knows precisely who we are, what we carry, and how we fight."
The old draenei turned his head to look at Leylin. "And it is deeply interested in you."
Leylin looked down the long, dark hallway leading into the heart of Ulduar. His expression remained completely unreadable behind his mask, his eyes calm and cold as winter ice.
At his flank, Alleria Windrunner drew a fresh arrow from her quiver, resting it lightly against her bowstring. "Then we shouldn't keep it waiting."
Leylin offered a single, sharp nod.
"Move in," he said.
And together, the grand force stepped through the final threshold into the dark.
