Ten thousand years ago, after rebuilding Terra, instituting the Codex Astartes, establishing the Second Founding, and restructuring the High Lords Council, Guilliman led the loyalist fleet to pursue the traitors. Before departing, foreseeing danger, he summoned Archmagos Cawl and explained several things.
First: should anything happen while chasing the traitors, Cawl must find a way to save him.
Second: using the original gene-seed containing the primarch's genetic material, Cawl must further empower and enhance the Astartes.
Cawl bowed and swore to fulfill these tasks. To a mortal bound by promises, ten thousand years—though but a moment in the universe—was enough to travel across the galaxy. Cawl explored ancient ruins, lost Forge Worlds, even xenos domains, collecting unknown knowledge and conducting experiments. Eventually, he fulfilled the Primarch's task—crafting the Armour of Fate and, with Eldar assistance, awakening Guilliman from stasis on Macragge.
Thus, the new generation of Space Marines, the Primaris, was born—gifted to the revived primarch.
The classic Space Marine undergoes 19 organ transplants and surgeries:
Muscle enhancement, secondary heart, tertiary lung, neural nodes, implanted stomach, gene-seed glands, etc. These enhancements grant physicality and reflexes far beyond ordinary humans, allowing them to survive and fight in the harshest environments.
The new Primaris Marines boast three additional organs atop these 19: tendon coils, the hymn pituitary, and the Belisarian Furnace. These confer even stronger skin and muscle, greater speed, strength, height, and survivability.
When Guilliman formally announced the existence of the Primaris Marines and the plan to elevate the Imperium's power, it immediately caused a sensation. After the initial shock, Chancellor Tieron realized that Irthu and the others—steeped in millennia of bureaucratic inertia—could never have won; they were doomed, no more than pathetic clowns, especially in the face of such a trump card.
To visually demonstrate this new military might, Guilliman chose to unveil the force aboard Cawl's other technological marvel: the Ark Mechanicus "Zar-Quaesitor". Imperial dignitaries and generals, like flocks of pilgrims, boarded various aircraft and followed crowded flight paths to the immense iron giant floating in the void.
The Zar-Quaesitor was colossal—not simply a ship, but a self-sustaining hive city in space, equivalent in scale to the capital of a major world. A blueprint from the Dark Age of Technology, originally an incomplete mega-frame, found dormant. Cawl invested millennia and uncountable resources turning it into a technological ark.
…
Having resolved the traitors, Datch found himself without urgent business on Terra. He settled into daily life, descending to the underhives to repair generators and pipelines, truly stepping into a new age of the Warhammer universe as a young man.
Upon learning of the Primaris, Datch prepared to move the plot forward alongside the other NPCs. Leaving Terra's surface for the void, he saw that the full-scale mobilization of the Indomitus Crusade had made space busier than ever—ships packed the void, battleships arrayed like mountains of steel, their armor gleaming coldly under the stars. Sharp-lined heavy cruisers prowled like sharks. Many transports, repair barges, recon vessels, and supply ships bustled about, swarming protectively around the central massive vessel. Huge troopships endlessly ferried the Astra Militarum. Cargo barges, deadly Mechanicus battle engines, and columns of vital supply ships stretched as far as the eye could see. Salvage ships and fast scouts nipped between the fleet like ants around a queen. Looking out his porthole, Datch saw a sea of ships spanning the horizon—humanity's greatest military force since the Emperor's own Great Crusade, its might enough to awe any witness.
Inside the Zar-Quaesitor, Datch marveled at the ark's vastness. It was less a ship than a layered, steel-clad world. Cavernous spaces divided into countless areas:
The roaring Forge Temple,
Meditative Matrix Farms streaming overwhelming data,
Expansive ranges for weapons testing,
Vaults for rare materials...
The sounds of machinery, turning gears, and plasma arcs, and the scent of oil vapor, merged into an endless industrial hymn.
Without an escort, Datch roamed the complicated corridors alone, using his minimap to help explore the giant ark. He never let go of any loot-boxes encountered—most held parts, but sometimes there were interesting finds. Datch often packed these into his room for later.
While idly wandering, Datch was drawn to a massive warehouse filled with new war equipment on display: tanks, dreadnoughts, gunboats, void-fighters, all neatly arranged, upgraded with advanced technology for improved firepower and mobility, modular in design to suit varying mission needs—and notably, much larger in size, evidently meant for the new Astartes.
"Tch, Cawl wasn't wasting his ten thousand years after all," Datch thought, examining the gear, when suddenly a golden question mark appeared on his minimap, signaling a plot mission.
Following the minimap, Datch soon found a high platform. The marker hovered above the head of a person leaning against the railing, overlooking the immense assembly line.
The figure wore black and red Inquisitorial robes, tall and with a cold demeanor—it was Kleopatra Arx, Inquisitorial Representative.
Datch bounded onto the platform and approached.
"Kleopatra Arx, need any help?"
Arx, hearing his voice, looked at Datch with a slight frown.
"Nameless One, you're here as well?"
Datch called, "Skip." Then repeated, "Kleopatra Arx, need any help?"
Arx' face fell speechless. She finally understood why even the primarch was powerless against the Nameless One—every conversation, he interrupted with "Skip, skip!" yet nothing could bring her down. Still, uncertain whether to share her latest troubles with him, she hesitated.
Datch persisted, asking again, and Arx finally sighed and shared her concern:
"Recently I received a tip—an Alpha Legion serpent emblem has been found. We suspect those traitors have once again infiltrated the Sol System, likely to sabotage the Indomitus Crusade. But for now, we have no clues.
Nameless One, can you help investigate? I want to unearth the truth and bring them to justice before they can do real harm."
Datch suddenly saw a mission panel rise before him.
[Mission: Hunt the Hidden Alpha Legion in the Sol System]
Roboute Guilliman's mobilization order for the Indomitus Crusade has drawn countless warships to the Sol System, but also drawn the enemy's gaze. Inquisitorial sources report the Alpha Legion's serpent emblem has been found—they may have infiltrated Terra, plotting a deadly strike. Find and stop the hidden serpents before they do serious harm!
