Tyrone Hive Primus
War had found the Underhive.
Deep beneath Tyrone Hive Primus, below the manufactoria, below the hab-stacks, below even the sump-fed service warrens respectable citizens pretended did not exist, the hive-city rotted in layers of rust, heat, sewage, and abandoned machinery.
Imperial law reached these depths only when armed men carried it there, and even then it rarely stayed long. Gangs, fugitives, mutants, smugglers, scavenger clans, and starving refugees had fought over water taps and filter cartridges long before the current war.
Now that old violence had been given a new shape. What had once been raids, feuds, and killings in the dark had become a front line.
The only passage leading upward into the lower hive had been turned into a fortress by men with too little time and too few proper materials. Scavenged armor plate leaned against cargo containers. Corroded girders formed crude anti-vehicle barriers. Razorwire, sensor trip-lines, and half-buried mines covered the approaches where an old transit avenue narrowed into the main ascent shaft. The work was ugly, improvised, and already sweating rust in the damp air.
It also mattered.
That shaft was wide enough to move armor, bulk cargo, and heavy lift platforms between hive levels. If it fell, anything rising from the Underhive would have a direct route into the lower industrial districts above. From there, the enemy could spill into manufactoria, power-routing stations, and hab sectors that fed the rest of Tyrone Hive Primus. One broken gate could become a city-wide disaster.
So the Planetary Defense Force (PDF) of Talon I held the line. More precisely, the exhausted soldiers of the 44th Tyrone Infantry Regiment held it, because no one else was available to die in their place.
Captain Burr Halvorsen stood on a raised section of scrap decking overlooking the trench works, boots planted wide as if he could bully the hive itself into obedience. He was broad-shouldered, shaved bald, and marked by a scar that ran from one cheek to his jaw. His patched flak coat had been repaired so often that only the regimental badge proved it had once been standard issue. A chainsword hung at his hip, its teeth dark with old grime despite careful maintenance.
"Filth-licking dregs!" Burr bellowed. "While true soldiers bleed in the Emperor's name against that Evolutionist rot, you grovel like hive-scum! Move!"
A line of convicts hauling a support beam flinched as one. The beam slipped from their shoulders and struck the deck with a heavy metallic boom, shaking rust from the overhead pipes.
"Get moving!" Burr shouted, jabbing two fingers toward the half-finished supply revetment. "Build the supply points, reinforce the defenses, or I'll make sure you feel the lash!"
An overseer drove a shock-prod into the slowest prisoner's back. The man spasmed, teeth clenched too tightly to scream, then lurched forward and forced his shoulder under the beam again.
"Faster!" Burr roared. "We don't have time to waste!"
His voice cut through the trench line alongside the brutal music of labor: hammers striking bolts, welding torches hissing against scrap plate, ammunition crates scraping through mud, vox-operators reciting position checks, and distant weapons fire rolling through the deeper tunnels.
The PDF troopers watched the darkness from firing pits carved into the hive's ancient metal bones. Their lasguns rested across sandbags. Their helmets were dented and marked with chalked kill-counts, prayer strips, or the names of dead squadmates. Some forced down ration paste without taking their eyes off the approach. Others slept upright against barricades, hands still close to their weapons. No one removed their boots. No one trusted the silence.
But Burr's rage was not aimed at them. It was aimed at the chain-gang of prisoners pressed into service behind the line.
They were not engineers. They were bodies taken from holding cells, labor camps, and penal transports after the regiment ran out of servitors, machinery, and patience.
Men and women in shackles hauled shells, mixed quick-setting ferrocrete, welded plates into place, and dragged beams through the mud. Their hands were split. Their prison rags were stiff with sweat, dust, and old blood. Some wore explosive restraint collars. Others carried identification brands burned into cheek, neck, or hand. A few had both.
Many had already died building the line, not from enemy fire, but from crushed limbs, infection, exhaustion, or a shock-prod applied once too often to a heart that could no longer endure it. The bodies had been dragged into side tunnels and burned for "sanitation." The practical reason was simpler: dead prisoners attracted scavengers.
Among the living sat the man who called himself Qin Mo.
He had not been excused from work. The labor rotation had merely paused, and even Burr understood that a man collapsing while carrying munitions could take half a trench section with him. Qin Mo rested on an overturned crate near a stack of empty promethium cans, shoulders bent, wrists still bruised by shackles.
His shirt hung in rags. Beneath it, dark metallic etchings traced strange geometric patterns across his forearms, collarbones, and neck. They were neither tattoos nor scars. They looked more like circuitry buried beneath the skin, thin pathways that caught the welding light like polished metal. Most people who noticed them looked away quickly. In the Imperium, the unfamiliar was safest when ignored, reported, or killed.
Around his throat hung a psyker suppression collar: a battered iron restraint ringed with hexagrammic wards, silvered pins, and dull sigils meant to smother psychic activity before it became useful, dangerous, or both. A small engraved plate had been riveted to the front.
Prisoner No. 444.
Unlike the collars worn by most of the penal laborers, Qin Mo's was not merely a restraint.
It was a cage for the mind. A leash for an untrained psyker.
....
A hunched figure approached Captain Burr through the trench, moving with the careful slowness of someone whose body had been used hard for longer than most soldiers had been alive. Troopers noticed him before Burr did. They shifted aside without being ordered, opening a narrow path through mud and scrap. None of them wanted his robes to brush against them.
The old man stopped three paces from Burr and bowed with rigid, ritual precision. His right hand rose in the sign of the Aquila. The gesture was correct. The timing was correct. It carried every ounce of respect doctrine demanded, and none of the warmth that would have made it sincere.
"My lord captain…" His voice rasped like parchment dragged across stone.
Burr turned. Recognition settled into his face, followed immediately by irritation.
"Kalon."
The sanctioned psyker's presence was a necessary blasphemy, and everyone nearby knew it.
Kalon's robes, once the deep violet of the Scholastica Psykana, hung in faded strips beneath a stained flak mantle. Frayed hexagrammic wards covered the fabric, many repaired by hand with wire, thread, and devotional seals. A brass sanctioning brand rested against his chest on a chain, polished by nervous fingers rather than pride.
His face was lined with old scar tissue. His eyes were milky, pupil-less slits that never seemed to blink. The skin around them had the tightened look of flesh that had survived too many rituals, too many visions, and too many punishments for seeing what others could not.
He was one of the rare psykers who had survived sanctioning, service, suspicion, and age long enough to become part of a regiment's furniture. That did not make him beloved. It made him useful.
A subtle pressure surrounded him, like the feeling before a storm inside a sealed room. Soldiers avoided standing too close. One made the sign of the Aquila. Another muttered a warding prayer. A third stared at his own boots, pretending the old psyker had not passed within arm's reach.
"You decrepit old bastard," Burr sneered. "Always interrupting me. This had better be important."
Qin Mo lifted his head slightly from among the convicts. He did not move quickly. Sudden movement drew attention, and attention in a penal work gang usually ended with pain. Still, his eyes followed the exchange.
He knew enough about the Imperium to understand how unusual Kalon was. Most psykers were taken by the Black Ships. The lucky ones were branded, trained, conditioned, monitored, and deployed as tools that could touch the warp without immediately destroying themselves. They were weapons and liabilities. They were not usually treated as an officer's familiar nuisance.
Kalon and Burr had history. It showed not in kindness, but in habit. Kalon knew how far he could step before Burr pushed back. Burr knew how much insult the old psyker would absorb before the conversation became inconvenient.
"They are exhausted," Kalon said. His blind gaze swept across the convicts with unsettling accuracy. "We need them alive. Let them rest."
A nearby overseer opened his mouth, saw Burr's face, and wisely closed it again.
For several seconds Burr said nothing. His gaze moved over the work gangs, the unfinished revetments, the sagging barricades, and the laborers swaying on their feet. One woman braced both hands on an ammunition crate and breathed through her teeth. A boy with a prison brand on his cheek blinked as if the trench lights had become too bright. Another convict's hands shook so badly he could not hold a welding torch steady.
Burr hated being corrected. He hated losing work hours. But he hated waste more. Dead laborers did not carry shells.
He exhaled sharply through his nose.
"Fine."
The word cracked across the trench like a concession dragged out by force. Burr pointed at the overseers.
"Ten minutes. Water first. Rations after. Anyone sleeping through the call gets dragged back up by the ankles."
The convicts did not cheer. They knew better. Relief showed in smaller ways: shoulders dropping, tools lowering, bodies sinking where they stood as if someone had cut their strings.
PDF logistics personnel arrived with ration crates under armed guard. The crates were stamped with Administratum inventory marks, regimental supply codes, and purity seals already peeling in the damp. Packets were tossed into waiting hands as if the soldiers were feeding sump-rats.
"444." A young trooper with tired eyes and a dirty bandage around his left wrist shoved a ration block toward Qin Mo. "Your rations. The Emperor provides."
The phrase came automatically. The trooper did not sound convinced.
Qin Mo caught the nutrient block and inspected it with the mild indifference of a man evaluating something that qualified as food only because the Departmento Munitorum had signed the correct form.
It was standard military issue, superior to the starch-based substitutes fed to lower-hive laborers. Not out of generosity, of course, simply because it was easier to distribute a single type of ration across the PDF forces and their expendable labor. He peeled open the waxed wrapper. Inside sat a dull white cube with the texture of dried soap.
He took a bite.
It tasted worse than wax.
The cube dissolved into chalky paste and clung to his teeth with the determination of industrial sealant. His stomach tried to rebel. Qin Mo forced himself not to gag; choking to death on a ration block in the Underhive would be an offensively stupid way to die.
Congratulations, he thought. You have survived another encounter with Imperial cuisine. Truly, the Emperor protects.
The joke helped just enough to keep his mind his own.
He wiped his mouth with the back of his hand and reached into the inner fold of his ruined shirt. His fingers closed around a small object wrapped in cloth.
A journal.
It was battered, frayed, and stained by grime. The binding had been repaired with thread, wire, and what might once have been medical tape. Several pages were yellowed from damp; others had been torn out, folded back in, or reinforced at the edges. Ink and graphite showed beneath fingerprints, old blood, and Underhive dust.
It was more than a diary.
It was a lifeline.
Within these pages were the fragments of another life. His life. Before this nightmare. Before the absurd fact that he had awakened inside the Warhammer 40,000 universe, a setting he had once known as fiction, lore, jokes, arguments, and late-night wiki dives.
The pages held ordinary things: names, faces, habits, half-remembered conversations, songs he used to like, games he used to play, small memories that had once seemed too mundane to preserve. Now they mattered because they proved he was not merely Prisoner No. 444. Not merely an untrained psyker. Not merely another doomed body in a trench beneath a dying hive.
He read while soldiers muttered prayers, convicts chewed in silence, welding torches hissed, and the Underhive breathed poison through broken vents.
Despite everything, Qin Mo smiled.
....
He did not notice Burr and Kalon approaching until their shadows fell across the page.
The two men stopped in front of him. Burr glanced toward Kalon. The old psyker gave no visible response, but some silent understanding passed between them. Burr's jaw tightened, not in anger this time, but in curiosity sharpened by irritation.
Qin Mo looked up too late to avoid the lesson.
Burr shifted his stance and struck the side of Qin Mo's head with the flat of his chainsword. The weapon was not running, but the slab of metal still hit hard enough to turn his vision white for a heartbeat.
"Ha!" Burr barked. "Still awake, 444?"
The overseers chuckled because Burr had laughed. The convicts did not. They watched from the corners of their eyes, careful not to be caught watching.
Qin Mo steadied himself against the crate. Pain pulsed above his ear. Warmth gathered beneath his hairline. He drew one slow breath, then lifted his head.
His eyes were blue as the void.
For one brief moment, Burr felt something ancient tighten behind his ribs. It was not fear as he understood it. Burr knew fear: artillery landing too close, a jammed lasgun while shapes climbed the barricade, a vox-officer screaming that the flank had gone silent. This was colder. Older.
For that second, Qin Mo did not look like a frightened prisoner, an unstable psyker, or a condemned laborer nursing resentment. His gaze was calm. Too calm. Vast in a way no human face should have been.
Cold sweat formed along Burr's neck.
Then the sensation vanished. Qin Mo blinked once, and the eyes facing Burr were merely strange instead of wrong.
"Psykers," Burr muttered, forcing contempt into the word because contempt was easier to trust than unease. "Always so dramatic."
Kalon raised one hand.
Qin Mo's journal lifted from his grip and floated into the old psyker's waiting palm. Several soldiers stepped back at once. One whispered the first line of a warding catechism. Another made the Aquila so quickly his fingers shook.
Qin Mo's eyes followed the journal, but he did not reach for it. The collar sat heavy around his throat. The overseers had shotguns. Burr had a chainsword. Kalon had the key to whatever passed for mercy down here.
More importantly, anger was useful only when it achieved something.
Kalon turned the pages with thin, careful fingers. He did not treat the book like contraband or evidence. He handled it like an object whose value he could sense but not understand. His milky eyes moved across the writing once, twice, then back again.
Burr smirked. "What's he got in there? Insane psyker scribbling?"
Kalon did not answer immediately. The delay lasted long enough for Burr's smirk to fade. The old psyker turned another page, then another. At last, he closed the journal and held it out.
"I cannot read it."
Burr frowned. "What?"
"It is not written in Gothic," Kalon said. "The structure is unfamiliar. The symbols repeat, but they match no Imperial dialect I know."
Qin Mo took the journal back. His fingers closed over it too tightly before he forced them to relax.
Kalon turned his blind gaze toward him.
"But it is not the writing of a corrupted mind," the old psyker continued. "There is no warp-taint clinging to it. No devotional inversion. No compulsive patterning. No residue of possession." He paused, choosing the next words with care. "You may be untrained, but you are still sane."
The statement settled over the little circle like a tool placed on a table. Not comfort. Not kindness. Something practical.
Qin Mo almost laughed.
Sane, he thought. Great. Put that on my tombstone. Here lies Qin Mo. Mentally stable by the standards of the Imperium.
A burst of autogun fire echoed beyond the barricades. The nearest PDF soldiers stiffened, waited for the alarm, then relaxed when none came.
Kalon spoke again.
"Prisoner No. 444. Why were you arrested?"
Burr folded his arms, clearly expecting a confession, a sob story, or the rambling evasions of a man hoping words could save him.
Qin Mo met Kalon's blind gaze directly. His voice stayed even.
"A noble mistook me for prey during a hunt in the lower hive," he said. "So I burned him alive."
The nearest overseer stopped chewing. A PDF trooper looked from Qin Mo to Burr as if waiting to see whether the captain would execute him on the spot.
Burr's mouth twitched. Not quite a smile. Not quite approval.
Kalon extended his senses toward Qin Mo's mind. Qin Mo felt nothing directly, but he saw the old psyker's fingers tighten around his staff. Kalon's head tilted a fraction, as if he had stepped forward expecting a wall and found open air instead.
There was no surface thought to brush. No fear to taste. No memory rising in response to the question. No lie, no truth, no shield shaped by any discipline Kalon understood.
Only absence. It was like probing empty space.
For the first time since he entered the trench, uncertainty crossed Kalon's scarred face.
Burr noticed immediately. Burr noticed weakness the way a sump-rat noticed blood.
"Well?" the captain demanded. "Is he lying?"
Kalon answered slowly.
"I do not know."
Burr scoffed, but the sound lacked confidence. "You don't know?"
"I cannot enter his mind," Kalon said. "I cannot even find the edge of it. I have never encountered that before."
That drew more attention than Qin Mo wanted. A soldier glanced back from the firing step. One overseer shifted his grip on his shotgun. Nearby convicts lowered their eyes, silently deciding that Prisoner 444 was dangerous in a way they did not want associated with them.
Burr's frown deepened. For a moment, he looked at Qin Mo not as a prisoner, but as a battlefield problem: unknown capability, unknown reliability, possible asset, possible catastrophe. Then practicality overruled superstition.
"Doesn't matter," Burr said. "We need manpower."
Qin Mo narrowed his eyes slightly.
Now the real conversation was beginning.
Kalon confirmed it moments later.
"We need your abilities," the old psyker said.
He reached beneath his sleeve and raised a small metal key attached to a thin chain. It was plain, almost unimpressive, but the teeth were etched with tiny ward-marks cut for a mechanism designed to unlock more than iron.
"The override key to your suppression collar is in my possession."
Qin Mo's eyes moved from the key to Kalon's face. Burr watched him closely, one hand near his chainsword, the other resting against his sidearm. Soldiers shifted their weight, sensing danger without understanding its shape. Even the air seemed to tighten around the little circle.
Qin Mo said nothing.
The collar sat heavy around his throat. Beneath it, the metallic patterns in his skin caught the trench-light, flashed once, and vanished again.
Kalon's next words were calm and direct.
"When the time comes…" The key glinted between his fingers. "I will unlock it."
