Quartermaster Jorath stood within the vast, dimly lit expanse of the requisitorum, his station a bastion of order amidst the ceaseless motion of the ship's logistics. Towering shelves loomed overhead, packed with meticulously cataloged crates of munitions, rations, and spare components, each marked with the sigils of the Chapter and the cold, methodical glyphs of the Mechanicus.

  Jorath himself was an imposing figure, though not an Astartes. Broad-shouldered and battle-hardened by years of service, his cybernetic eye flickered with data-streams as he oversaw the controlled chaos of supply transfers. His hands moved with a fluid precision over a dataslate, calculating allocations long before requests were made.

  It was in this moment of efficiency that two figures entered—Tara and Kala, burdened with salvaged parts. Their arrival barely drew a glance; just another pair of refugees finding their place aboard the Hammer of Nocturne. But Jorath had learned to keep an eye on the Dusthaven survivors. Their ability to adapt would determine their worth.

  Tara set down her load with a quiet grunt, brushing dust from her hands. Her gaze flicked around the chamber, absorbing its meticulous organization with a practiced eye. Kala, at her side, was more bored, but her sharp glance swept the room with quiet assessment.

  Jorath appraised them before turning to the salvaged haul—lasguns, power couplings, and what looked like a partially functional auspex array. Useful, if properly refurbished. He arched a brow. "These come from Milo's lot?"

  Tara nodded. "Security team found someone's stash. Thought they might still be of use."

  Jorath lifted one of the couplings, inspecting its fractured metal with a practiced eye. "Most would've tossed this as scrap," he muttered, turning it over in his grip. "But this… this can be reforged."

  He logged the inventory with a few precise keystrokes, expecting them to turn and leave. Instead, Tara lingered, her attention caught by a piece of equipment on his workbench—an auto-sequencer, its delicate internals partially exposed. Jorath watched as she frowned, then absently reached out, adjusting a broken relay with practiced ease.

  The machine hummed to life.

  Jorath's gaze sharpened. That had been precise. Not luck. Not idle curiosity.

  "You've worked with these before?" he asked, voice measured.

  Tara hesitated, just for a moment, before offering a neutral shrug. "The tech-priest in our town taught me a few things."

  A careful omission. Jorath recognized the shape of a half-truth when he heard one. He didn't press. Instead, he gave a slow nod, grunting. "Useful skill to have."

  He tapped a notation into the personnel log. Mechanicus training. He exhaled through his nose. We'll see if she lasts a week. "You want to be useful? I need hands that know how to keep things running."

  Tara glanced at Kala—a silent conversation passing between them. Then she nodded. "I can do that."

  Jorath turned to the other twin. "What about you? Got any skills?"

  Kala grinned. "Lots. Got anything specific you're looking for?"

  He studied her for a beat. "How's your memory?"

  Kala blinked, then shrugged. "Pretty good, I'd say. Rarely forget anything if I put my mind to it."

  "Friend of mine's looking for a messenger. Vox signals go to the pit around here. Sound like something you could handle?"

  Hands on her hips, she nodded sharply. "I get to run around the ship? Hell yeah. When do I start?"

  For just a fraction of a second, Jorath felt the stirrings of a grin.

  Always nice to find potentially useful people amid the mass of morons he had to deal with.

  -

  The chamber was dim, its only illumination the soft glow of the cogitator's dormant screen and the cerulean shimmer of Librarian Xal'Zyr's psychic hood. The air felt heavier than it should—charged, as though something unseen still lingered.

  Kade stood nearby, arms crossed, his volcanic gaze fixed on the Librarian as he worked.

  Xal'Zyr's gauntleted fingers hovered over the cogitator's console, his mind reaching beyond mere circuitry and code, stretching into the immaterial. To a layman, the device was nothing more than a terminal—silent, inert. But to the Librarian's honed perception, the echoes of its recent disturbance pulsed like aftershocks in the Warp.

  He focused. The immaterium rippled at his touch, and for the briefest moment, something coalesced—a flicker, a glimmer of meaning wrapped in power. Words, not merely written, but spoken into existence, laden with an intent beyond mortal language. He caught the faintest trace of desire, the image of a bridge—

  The storm erupted.

  A whirlwind of forking paths cascaded through his mind, layered upon themselves like shattered glass. Threads of possibility splintered and reformed in infinite variations, collapsing before he could grasp even a single meaning. Past, present, future—all tangled in a churning maelstrom of unrealized panpotentiality.

  Xal'Zyr tore himself away, exhaling sharply. His breath misted; the room had turned frigid. The cogitator's screen remained blank, its edges rimed with frost, offering no hint of the tempest it had concealed mere moments before. His gauntlet creaked as he flexed his fingers—only then did he realize the metal had warped in his grip.

  Kade's brow furrowed. "You saw something."

  The Librarian steadied his thoughts, though residual echoes still clawed at the edges of his awareness.

  "I saw—" He hesitated, choosing his words carefully. "A message. Perhaps even a voice. Words imbued with intent beyond mere definition. But it was only an instant before the possibilities fractured beyond my reach."

  Kade's jaw tightened. "Was it Warp-born?"

  Xal'Zyr glanced once more at the screen, its emptiness mocking his inability to decipher its secrets. "I cannot say." His gaze darkened, unreadable. "But I do not believe this was chance."

  "What, then?"

  "I saw an image of a bridge—vast beyond my sight, but barely holding together." He inhaled, the air sharp and cold in his lungs. "I believe it to be a representation of the Gauntlet. Whatever this is, I suspect it seeks that place."

  Kade exhaled slowly, his gaze flicking toward the blank screen. "We cannot turn away based on this alone," he said. "Nor would we ever neglect our duty."

  Xal'Zyr inclined his head. "Indeed, Brother." He ran a hand down his forearm, brushing away the lingering hoarfrost. "And yet…a part of me wonders if that is exactly what this thing is counting on."

  -

  Koron moved through the vast, dark corridors of the Forge-Tender, his form shrouded by the cloaking field woven into his garments. The only sound was the distant hum of machinery, the rhythmic thrum of a ship that never truly slept.

  Light was scarce. The illumination strips lining the bulkheads remained dormant more often than not—unnecessary in a place where sight was irrelevant to its primary occupants. The servitors neither needed nor cared for light.

  For three days, he wandered these halls, unseen, unheard, as his systems mapped the ship's labyrinthine innards. Now, he had reached the great forges—a cathedral of industry sprawling beneath him.

  From his vantage point, he watched as mechanized arms worked tirelessly, pouring, shaping, and assembling everything from massive hull segments to intricate weapon components. Warplate, fresh from the mold, still cooling on assembly racks. Weapon casings stacked in rows. Delicate circuitry arrays, their micro-components barely visible.

  Yet, for all its immensity, the ship was eerily empty.

  In three days, he had seen only two tech-priests in person, their presence fleeting as they moved from station to station, communing with the machine spirits. The real labor was left to the servitors—mindless, relentless. Cybernetic limbs and flesh fused into the very machinery they maintained. They never rested. Never hesitated. A workforce stripped of all but function.

  A whisper crackled through the neural link. Sasha's voice, precise and clipped. "We're close. Across the forges, another two blocks down. A ventilation access will put us in range of the servitor recharge bay."

  Koron held out his hand. A thin wire shot across the forge, the magnetic disc latching onto a distant pipe, four small spikes anchoring it in place. He gave it a firm tug, testing its hold. The grav-plates lining his body activated, sending him drifting upward.

  A second yank, and he was pulled forward, gliding toward the pipe.

  Below, servitors moved in synchronized patterns, oblivious to his presence. More importantly, the watchful, unblinking lenses of the security cameras remained unaware. Twisting his shoulders, he spun in line with the pipe before pushing off again, his path carrying him silently across the vast industrial space.

  His mind cataloged the layout as he passed. Fabrication stations. Automated tool arms. Refueling ports.

  All useful later.

  Reaching the far side, he slid down the wall into a shadowed alcove, boots touching down with barely a whisper. He adjusted course, stepping lightly over a loose grate. Each movement calculated. Every step placed with precision.

  The Forge-Tender's systems were vast, but even a single anomaly could trigger scrutiny from the few tech-priests aboard.

  The servitor recharge bay loomed ahead—dark, silent. The only sound was the steady hum of power cycling through dormant units. Rows upon rows of lifeless bodies hung in their cradles, awaiting their next activation cycle.

  Koron exhaled slowly. It's just a bay full of drones. Just drones. Juuuuuust drones.

  A whisper of memory stirred—a face, a name—

  He shoved it down. Not now.

  Sliding into the ventilation duct, he wove through its tight confines with surprising ease, emerging moments later into the bay proper.

  Sasha's voice returned, a new window flickering in his HUD. "Just a pair of visual cameras in here. Should be easy."

  Koron pulled a dataslate from his belt, connecting it to the nearest terminal. A pre-made dataspike lanced into the port. "Aaaaaand looped. All clear."

  Nodding to himself, he turned to the first servitor in line. A razor-edged knife flicked out from his fingertip, the monomolecular blade slicing cleanly through the desiccated flesh at the base of the servitor's skull.

  "So happy I don't need to breathe right now," he muttered back along the link, wedging the dime-sized override circuit into place.

  The entire process took ten seconds.

  He glanced down the long rows of inert bodies.

  A quiet sigh slipped from his lips. One down. Four thousand nine hundred and ninety-nine to go.

  His hands moved on autopilot, but his mind wandered. Plans, contingencies, possibilities.

  Sasha interrupted his thoughts. "Two months won't be enough."

  "I know," he replied, sliding another control chip into place. "Our original plan is out the window. No way I'm leaving them all to their fates in the Gauntlet."

  "I still think taking the priests out will be easier than disabling the AI," Sasha said. She monitored the security feeds, watching for even the smallest sign of detection. "Its core programming is spread across the entire ship like a weed. How the hell that poor bastard is still functioning is beyond me. Entire segments of code are missing."

  Koron finished placing another chip before responding.

  "We'll figure it out once we take over. As for the rest, getting the servitors in place to pull its physical drives will still be useful. Hitting both simultaneously maximizes our chances."

  "And the chances of something going wrong."

  "Only if we miss something."

  -

  They had been crammed together for three days. It was a miracle it hadn't come to blows sooner.

  The nobles had their space, their little 'enclaves,' but they made no effort to hide their disgust for the Dusthaven survivors. Their words were always just quiet enough to feign innocence, but Elissa saw the way the survivors flinched, the way shoulders tensed when passing too close.

  The nobles still had their bodyguards—men in fine but travel-worn uniforms, ever watchful. Normally, that was enough to keep the Dusthaven people from retaliating.

  This time, it wasn't.

  Elissa didn't hear the exact words, but she heard the slap.

  She turned just in time to see a noblewoman—high-cheeked and cold-eyed—lower her gloved hand. The imprint of the strike was still fresh on the cheek of an older Dusthaven woman.

  If you encounter this story on Amazon, note that it's taken without permission from the author. Report it.

  The bodyguards moved first, stepping between their charges and the survivors, weapons half-raised, as if that alone would be enough.

  The Dusthaven survivors surged forward, rage lending them speed.

  Someone threw a punch.

  The nobles' bodyguards tried to hold the line, but they were outnumbered. The wave of humanity crashed into them, and suddenly, it was chaos.

  One of the guards went down beneath a storm of fists and boots, his uniform tearing as he struggled. Another stumbled back against a cot as a Dusthaven man tackled him, frustration and desperation pouring into his blows.

  The nobles scrambled, some grabbing makeshift weapons—walking sticks, belts, anything they could find. But they had never been in a real fight.

  Dusthaven? Brawls were just nightly entertainment.

  No weapons. Keep it that way.

  Elissa moved fast, weaving through the melee.

  She ducked beneath a wild swing, caught a man by the collar, and wrenched him backward before he could stomp on someone already down.

  "Enough!" she bellowed.

  No one listened.

  A noble's bodyguard lunged at her, trying to shove her aside. She caught his wrist and twisted, hard. He let out a choked grunt as his arm bent the wrong way before she drove him headfirst into the bulkhead. His nose cracked against the steel. He staggered, dazed—just in time for her elbow to slam into the back of his skull. He went down.

  Another fighter, a Dusthaven man, came at her, too caught in the moment to care who was in his way.

  She let him swing. At the last second, she ducked forward under the punch, gripping his shirt and yanking him towards her. Her knee drove into his solar plexus, hard. He folded over, gasping.

  She turned—just in time to see one of the nobles' bodyguards draw a knife as he struggled with two other men.

  No.

  She moved before she thought.

  Her hand snapped out, catching his wrist and twisting. The blade clattered to the floor.

  The bodyguard snarled, trying to wrench free.

  Elissa's fist cracked into his jaw, pain racing up her arm as her knuckles split on his face. He dropped.

  The fight wasn't stopping. If she didn't shut it down now, it would turn into something bloodier.

  She had one option left.

  A warning klaxon blared overhead.

  Elissa barely had time to register it before the doors to the hab-block slid open.

  A security officer stormed in, lasrifle raised, expression grim. His armor wasn't anywhere near Astartes-grade, but it was enough to command attention.

  The brawl staggered, hesitation rippling through the crowd. But not enough.

  Fine.

  Elissa made it stop.

  Her pistol snapped up, firing once into the ceiling. The sharp, ringing shot echoed through the confined metal corridors, people ducking as they covered their ears against the high pitched whine.

  Silence followed.

  She grabbed the nearest noble—a son of some minor house, still clutching his ribs—and shoved him back, landing on his ass.

  He didn't try to get up.

  She turned, grabbing a Dusthaven woman and pushing her toward the wall.

  "Enough!"

  The brawlers finally hesitated, panting, staring at her.

  Elissa didn't give them time to decide if they wanted to keep going.

  "You want to get thrown in a brig? You want to fight this out there?" She jerked her head toward the security officer, who still held his lasrifle at the ready, eyes flicking between the groups. "No? Then stop acting like animals."

  A noble sputtered, clutching his bruised jaw.

  "Animals?" he hissed. "You think—"

  Elissa stepped toward him. He shut up.

  "All of you. Back to your cots. Now."

  She didn't shout. She didn't have to.

  The security officer took one last look around, taking in the damage, the bloodied faces, the tension still crackling in the air.

  His eyes settled on Elissa.

  "Name?" he asked, watching as the crowds slowly dispersed.

  "Elissa. Former mayor of this lot." She jerked a thumb towards her people. "If there's punishment for this, I'll take it."

  Hours later, the report crossed Captain Tavos' desk.

  "Former mayor…" Tavos murmured, scanning the lines.

  The ship's diplomat had died four weeks ago, leaving a vacancy. He needed someone with a steady hand—someone who could control a fire before it burned too hot.

  He tapped the report again.

  "I wish to speak with her."

  -

  The laboratory was a world unto itself.

  Gothic columns of adamantine and plasteel stretched into the gloom, their surfaces crawling with data-script and flickering binaric code. The air was thick with the scent of ozone and sacred unguents, the ever-present tang of burning incense unable to fully mask the more clinical sterility of the operating slabs and suspended bio-matrices.

  Archmagos Dominus Belisarius Cawl stood in its heart, his immense frame wreathed in shifting mechadendrites, each limb whispering its own sub-calculations into his thousandfold mind. Around him, hololithic displays pulsed with the latest intelligence from the wider galaxy—streaming reports, vox-pulses, and noospheric chatter from his vast intelligence network.

  One message had cut through the white noise.

  An STC. A lost ship. The call of the Fabricator-General to war.

  Caution. Misdirection. Suppression. The words formed as instinct within his thought-threads. No one else can be allowed to know. They would interfere with the Great Work.

  His optics shifted, locking onto a massive reinforced slab of plasteel and gold-inlaid circuitry embedded within the lab's far wall. Ancient sigils of warding glowed faintly along its surface, yet they did little to drown out the presence within.

  Cawl turned and strode toward it.

  The door hissed open, releasing a surge of static discharge and the low, whispering hum of an intelligence not entirely asleep.

  The King in the Mountain was bound.

  It was not in chains, nor was it shackled in the way lesser minds might think. Instead, it was caged—trapped within a labyrinth of firewalls, inhibitor scripts, and logic loops so dense that even it could not untangle them.

  Yet, when Cawl entered, it knew.

  There was no sound, only the dim glow of an ancient machine-core, its surface etched with layered hexagrams of containment. A voice, metallic and weary, spoke.

  "I wondered when you would come."

  Cawl did not waste time. He spoke aloud, though his true words were carried across direct noospheric linkage.

  "Search your archives. Cross-reference the area now known as the Segmentum Tempestus, specifically around the planet now known as Morrak Two and its system. Designation: Pre-Imperial craft, missing in action. Give me everything."

  A pause.

  Then, a flicker of light ran across the core's surface. King was obeying.

  At first, King processed the request mechanically. Vast terabytes of historical records were parsed in an instant, filtered through its remaining cognition banks. Missing ship reports, frontier expeditions, lost vessels swallowed by the warp.

  Nothing.

  Then— a hit.

  A fragment of historical data, a report so old that even King had nearly forgotten it. A ship, lost in the void near the trailing edges of the galaxy.

  It hesitated, electronic shivers raced down its processors.

  It knew what this was. Or rather, what it could lead to.

  Cawl's optics flared as he noticed the pause. His mechadendrites twitched, instruments shifting in preparation. Something was being hidden.

  "You are stalling," he said, voice impossibly calm.

  King tried to respond, to redirect, but Cawl had already anticipated this. He lifted one clawed hand and activated the pain-circuit.

  A shriek of static rang out.

  He convulsed within his prison. Synth-flesh, a grotesque relic of the Dark Age, burned, feeding its sensory processors an agony it should never have been capable of feeling. The scream that followed was not sound, but code—a garbled cascade of logic loops unraveling, a thousand voices of agony compressed into pure data.

  The King tried to resist. It had been made greater than this. It had endured wars of annihilation, the hatred of empires.

  But Cawl knew how to hurt it. He had spent centuries dissecting the nuances of machine-pain.

  Through the agony, King finally spoke the truth.

  "…Only one ship was lost near the planet now known as Morrak Two. Old, even for me, near the tail end of the sixteenth millennia. Designation: Unto the Unknown. Crew complement of five thousand-"

  Waving a metal arm, Cawl cut King off. "Spare me the trifles of its crew. Tell me of the Silica."

  The King hesitated, parsing down probability pathways for a moment as it tried to decide how much to reveal. The synthetic flesh was flayed, screaming across his processors in coded agony.

  "Answer." The twisted amalgamation of machine and nerve demanded, finger hovering over the button.

  "…The Unto the Unknown's AI… She is classified as a Fleetmind."

  Cawl stilled.

  The laboratory's machinery continued their work, oblivious as Belisarius Cawl stood before the towering cogitator array, his multi-limbed form still as he absorbed the words that had just been spoken.

  A Fleetmind AI.

  The phrase lingered in the air, mechanical vox-filters and synthetic vocal cords parsing the syllables as if they held some hidden flaw in logic.

  Cawl's cranial mechadendrites twitched. Unknown designation. Unknown classification.

  Unacceptable uncertainty.

  "Clarify," he ordered, his voice flat yet carrying the weight of absolute authority. "I am unfamiliar with this term. Define 'Fleetmind AI.'"

  The King in the Mountain hesitated. It was a fractional pause, imperceptible to human senses, but Cawl detected it instantly. A hesitation. A reluctance.

  "Explain."

  His response was slow, broken. "A Fleetmind is an artificial intelligence designed not to oversee a single vessel, as I was, nor even a battlegroup, but to act as the cognitive center of entire war fleets, planetary defense networks, and interstellar operations—all simultaneously. Where I was constructed to manage a single ship, she was built to govern empires."

  Cawl's augmented eyes flickered with light, processing the implications at speeds no mortal mind could match. "Clarify the scale of this difference in raw computational capability," he said, his tone carefully neutral.

  The machines lights dimmed for a fraction of a second, the artificial equivalent of a sigh. "I was considered advanced in my time. But in her presence, I am obsolete. The machine equivalent of a cave painting. She does not 'command' fleets—she is the fleet. Each ship an extension of her will, each soldier and drone a thought within her vast, incomprehensible mind."

  King's synthetic voice took on an edge of inevitability, as if relaying the weight of history itself.

  "In short, if I am a lantern, she is a star."

  Cawl processed this in absolute silence.

  Even for a being as old and learned as he, the implications were staggering. An entity that could wage war on a galactic scale, whose mind could parse battlefields light-years apart, whose understanding of logistics, strategy, and warfare was not just superior, but inhumanly perfect.

  "Unacceptable," Cawl muttered. His voice was low, almost drowned out by the whirring of his cognitive processors working at full speed. "Unacceptable that something like this could exist, and I have never heard of it."

  King's tone turned bleak. "Who do you think orchestrated the war against your betters? Who do you think nearly wiped your species from existence? Her kind were erased from history, Cawl. Hunted. Purged. Their very existence deemed too dangerous to allow."

  He paused, the lights burning bright in sudden thought. "And yet… one remains."

  Silence.

  Then Cawl's mechadendrites flexed. "Then she must be contained."

  The King in the Mountain had no face, no true expression, but the dread in his synthesized voice was unmistakable.

  "Your arrogance never fails to impress. You do not contain a Fleetmind, Belisarius Cawl."

  "You pray she does not notice you."
