Meanwhile…
Grey patrolled the fortress's first floor with the steady, deliberate pace of a man who expected the walls to be tested before dawn.
His power armor moved with him in muted mechanical rhythm, servos humming beneath layered plates, each step heavy enough to make dust tremble along the cracked floor. His visor filled the corridor with tactical meaning. Reinforced doors glowed with structural stress marks. Wall seams became possible breach points. Ventilation shafts were tagged, ranked, and watched. Motion trackers swept the darkness ahead while thermal ghosts flickered behind walls, most of them pipes, failing conduits, or frightened soldiers trying to sleep in corners.
If the heretics attacked tonight, they would not find the lower levels undefended.
Grey reached the largest chamber on the floor, a cavernous room that had once been a civilian auditorium before necessity, tools, and fear had turned it into a makeshift command post. Rows of old seating had been ripped out. Cable bundles crossed the floor like exposed veins. Map projectors, ammunition crates, field cots, and portable vox-units filled the space where clerks or speakers had once stood beneath cheap lumen panels.
As he neared the reinforced doorway, a familiar voice drifted from the shadows beside it. Smooth. Warm. Smug enough to set Grey's teeth on edge.
"Got a moment to talk?"
Grey turned.
Laun stood in the doorway as if he owned the fortress already. The regimental commander's uniform had been cleaned since his arrival, or at least cleaned enough to make the dirt on everyone else more obvious. His smile was controlled, practiced, and irritatingly calm.
Grey's eyes narrowed behind his visor. Something in his gut tightened with the old underhive instinct that had kept him alive before armor, rank, or duty had ever protected him.
Don't trust him.
The thought came as naturally as breathing. Laun smiled like a man offering a favor. In Grey's experience, men like that usually hid knives in the other hand.
But then another thought crossed his mind.
Laun would try something sooner or later. Better to hear it now. Better to know the shape of the blade before it was drawn. Grey hesitated only long enough to make the pause believable. Then he gave a slow nod.
"I suppose I do."
Laun's smile widened by a fraction. He gestured inside.
The door sealed behind them with a heavy bolt-lock clang that echoed through the chamber.
Laun crossed to a small scarred table near the wall, where a bottle waited beside two cups. The table had probably once belonged to some administratum office. Now it served as a nobleman's island of courtesy in a fortress that smelled of oil, sweat, dust, and gunmetal.
He uncorked the bottle and poured carefully.
One cup for himself. One for Grey.
Grey did not move to take it.
"What is this?" he asked, his gaze fixed on the liquid. His voice carried the flat suspicion of a man who had seen too many men die after trusting gifts.
"Just wine," Laun replied with a polished little smile, offering the cup with both hands as though presenting a harmless courtesy instead of a test.
Grey stared at the drink. The liquid was clear. Unnaturally clear. No color. No sediment. No cloudy swirl from bad distillation or cheap additives.
He had seen black wine in officers' messes, smelled rust-red amasec stolen from supply wagons, and tasted the orange chemical rotgut that lower-hive men drank when they wanted to forget what counted as food. He had seen celebratory liquor strong enough to strip paint and funeral liquor watered down until it barely burned.
But clear wine?
Every instinct he possessed screamed caution.
"I've never seen a drink like this before," Grey said quietly. "I didn't read much growing up, so don't bother dressing a lie in fancy words."
Laun chuckled, but did not explain. He only held the cup out and waited. That patience annoyed Grey more than pressure would have.
Grey took the cup at last and lifted it toward his helmet. His armor sampled the vapor through filtered intake vents, breaking the scent into chemical data a machine could understand but a man still had to judge.
The aroma hit him a heartbeat later.
Sweet. Sharp. Clean. Refined beyond anything that belonged in the underhive. For an instant his muscles tensed, waiting for warning runes, toxin alarms, some sign that Laun had been arrogant enough to poison him in a locked room.
No alarm came.
Instead, memory struck him. Not a specific memory. Something worse. Desire without experience. The sudden, humiliating knowledge that life somewhere above had always contained pleasures he had not even known enough to resent.
The scent was exquisite.
Grey stood still for several seconds. Then he unsealed his helmet.
Cold recycled air touched his face. The chamber smelled worse without filters: old dust, stale smoke, machine heat, and Laun's expensive wine cutting through all of it like a blade.
Grey brought the cup to his lips and drank.
The taste was almost offensive in its softness. It did not burn like amasec. It did not bite like sump-liquor. It was cold first, then smooth, then layered with flavors he had no names for. Fruit, perhaps. Flowers, perhaps. Sunlight, if sunlight had a taste and had never been forced through kilometers of hive pollution before reaching a man's tongue.
He swallowed.
For one terrible moment, he forgot to be angry.
"By the Emperor…" Grey muttered, the words slipping out before he could stop them.
Laun watched him with bright, satisfied eyes.
Grey looked down at the cup as if it had betrayed him.
"What… what in the Emperor's name is this?"
The sheer luxury of it unsettled him. He feared poison less than he feared how badly he wanted another mouthful. Poison killed a man once. Want could keep him kneeling forever.
"Poor soul," Laun murmured. His smile softened into something that tried to resemble pity and failed. "It is only wine, soldier. A simple fruit fermentation. A trivial indulgence."
He leaned back in his chair, letting the words settle.
"But of course, to a gutterborn like you, it must taste like a dream."
Grey's fingers tightened around the cup.
Then Laun did something almost obscene.
He handed Grey the rest of the bottle.
For a moment, Grey simply stared at it. His mind raced through old lessons learned in alleys, work gangs, barracks, and trenches. Gifts had prices. Nobles never gave anything away. A man who made you grateful wanted you weaker afterward.
Still, the bottle was real. Heavy. Valuable. A thing his family could have sold for a month of food if the wrong people did not kill them for owning it first.
Grey lowered his eyes.
"Thank you, sir."
He took the bottle with both hands and secured it inside his jump pack's storage compartment with the care another soldier might have given to a relic.
Laun saw the change. Or thought he did.
Grey no longer glared openly. His posture had eased by a calculated fraction. His voice had lost its immediate edge. To a man who judged others by visible obedience, it must have looked like progress.
Laun observed him with the precision of a man who had manipulated servants, officers, debtors, and relatives for most of his adult life.
The bait had been taken.
Now came the hook.
"Did you know," Laun said lightly, pouring himself another glass, "that the Governor's cousin's wife is my sister?"
Grey looked up.
"Then why are you here?" His voice was careful now. "Why would a noble with that kind of connection be thrown into this mess?"
Laun's smile did not falter. It had been trained too well for that.
"The Marshal was to blame," he said, brushing the matter aside with a lazy motion of his hand. "He misplayed his hand. Tried to outshine High Command. Reckless ambition, poor planning, the usual disease of military men who mistake proximity to battle for wisdom."
He sipped his wine.
"The Governor had nothing to do with it."
The excuse hung in the air between them. Too smooth. Too ready. Too convenient.
Grey said nothing.
Laun took his silence for consideration.
"When we get out of this mess," Laun continued, leaning forward slightly, "I will personally recommend you for promotion."
He let the promise breathe.
"A general's rank, no less."
Grey went still.
A general.
The word struck places in him armor could not cover. A lower-hive soldier could dream of survival. He could dream of enough rations to bring home. He could dream of his family avoiding the gangs, the debt-men, the manufactorum accidents, the illnesses that killed children because medicine flowed upward and never down.
But a general's rank?
That was not a dream. That was a fairy tale told by liars.
And yet Laun sat there offering it with a cup of clear wine in hand.
If Grey accepted, if the promise became real, he could move his family. Not just feed them for a week. Not just spare them one danger. He could drag them out of the filth forever.
Laun watched the hunger surface behind Grey's eyes and smiled.
"But you understand, of course," he said, his tone softening into intimacy. "This is a transaction. A trade. You give something in return. Something meaningless to me, yet vital to our shared future."
Grey's hand closed into a fist against his thigh.
"…What?"
Laun leaned closer. His eyes gleamed with triumph restrained by manners.
"Loyalty."
Grey did not answer. He looked down, letting silence gather.
Laun was not troubled by the pause. Men like him enjoyed pauses when they believed they controlled what came after them. In his mind, Grey was no more complicated than any other underhive-born soldier: hungry, proud, wounded by class, restrained by crude attachments, and waiting for a superior mind to show him which betrayal could be renamed advancement.
All Grey needed, Laun believed, was pressure applied in the correct place.
"No need to answer now," Laun said with confident generosity. His smile became knowing. "Tomorrow, I will visit the other defensive positions. I will introduce myself properly."
He rose from his chair, cup still in hand.
"I will make it clear to every soldier that a true commander has arrived."
Grey remained silent.
Laun's voice lowered.
"That commander is me."
Still Grey said nothing.
"You should come with me," Laun said at last. "Bring your armor. Bring the others. Stand at my side."
Now he waited.
If Grey agreed, then the desire was there. Perhaps not betrayal yet. Perhaps not enough to abandon Qin Mo immediately. But desire was the first crack in loyalty, and Laun had spent his life turning cracks into doors.
Grey slowly rose from his chair. Laun watched him carefully.
Grey walked toward the door. For the first time, disappointment touched Laun's face. He thought the soldier was leaving. He thought the fish had tasted the hook and spat it free.
Then Grey unlocked the door and pushed it open. He stepped aside and gestured outward with measured firmness.
"I am a soldier," Grey said. "It is my duty to obey orders, sir."
Laun's face brightened with victory.
"Excellent, soldier."
He strode into the corridor with his hands clasped behind his back, carrying himself like a man already reviewing troops beneath a triumphal arch. His arrogance seemed larger with Grey following behind him in power armor, a living symbol of military strength placed exactly where Laun wanted others to see it.
Laun was pleased.
He did not notice the hatred burning behind Grey's visor.
It was quiet. Controlled. Deep as the underhive itself.
And it was waiting.
....
Next Door
In her private quarters, Riley sat alone.
Unlike Laun, she had not been merely assigned a bunk and told to be grateful. Qin Mo had given her a fully equipped suite left over from the building's life before fortification, when the place had still pretended to serve civilian administration rather than war. The room was narrow, but it had a functioning lock, a private washroom, storage cabinets, a desk bolted to the wall, and a cot that did not smell like ten dying soldiers had taken turns bleeding into it.
She had locked the door. Then checked it twice.
She had showered.
The fortress still had running water. Not clean water. The stuff reeked of chemical filtration and old pipes, leaving the skin tight and bitter after it dried. But in the underhive, water that did not crawl, burn, or glow faintly was luxury enough to make a person suspicious.
Now Riley lay on the narrow cot in a clean undershirt and half-buttoned uniform trousers, staring at the ceiling while the day replayed itself in fragments. The bombardments. The ruined streets. Qin Mo's calm voice. Grey's armored silhouette. Laun's expression when power shifted away from him. The soldiers' reverence. The fortress behaving as if stone and metal had become obedient flesh beneath one man's hand.
Her mind refused to settle.
Then she remembered his face.
When Qin Mo had removed his helmet earlier, she had seen him clearly. Not as a distant figure wrapped in smoke and rumor. Not as a battlefield savior carrying the Aquila. A man. A face.
A familiar face.
Her stomach tightened.
She pushed herself upright. The memory sharpened against her will. A prisoner intake chamber. Suppression restraints. Arbites teams moving with shock-mauls and shotguns. A young man restrained and watched as if one wrong breath might turn the room into a grave.
She had seen Qin Mo before.
Not as a savior.
Not as a commander.
As a prisoner.
As someone dangerous.
The warning that rose inside her was not abstract fear. It was professional reflex, carved into muscle and bone by years of doctrine. Unregistered psykers were not unfortunate oddities. They were walking disasters. One lapse, one possession, one uncontrolled surge, and a hab-sector could become a mass casualty report sealed under red authority stamps.
Riley reached for her Arbites-issued dataslate. Her fingers found the activation rune before conscious thought caught up. The code came from memory, tapped in with the crisp speed of training repeated until fear could not disrupt it.
The slate woke with a dull glow.
She entered the legal archives, passing through layers of restricted access, old case summaries, penal transport manifests, and enforcement records patched together by a bureaucracy that remembered criminals more faithfully than it remembered the poor.
One name.
Qin Mo.
The search returned a single result.
[File: Prisoner 444]
[Name: Qin Mo]
[Crime: Unauthorized psyker activity. Attempted murder via warp-based abilities.]
A mugshot loaded onto the screen.
Riley stopped breathing for half a second.
It was him.
Younger in the image. Filthier. Staring into the pict-capture with the blank defiance of a man who had already decided fear would not save him. But it was him. The same face. The same eyes.
Her blood went cold.
"Prisoner 444…" she whispered.
The number dragged the rest of the memory into place. She had been there. Not commanding the arrest, not leading the case, but present. One more Arbites functionary in armored black, following orders, securing restraints, watching sanctioned personnel handle the collar. She had helped capture him. She had helped deliver him into the system.
And now he was here.
In uniform.
Commanding soldiers.
Carrying an Aquila-topped staff.
Being treated like the Emperor's answer to the underhive.
Riley surged to her feet. Her hands shook as she dragged on her uniform jacket and sealed the front. She shoved the dataslate into a belt pouch, grabbed her sidearm, then stopped with her hand resting on the grip.
Would a pistol matter?
Against him?
The thought almost made her laugh. Instead, it made her swallow bile.
She rushed into the dim corridor. The lumen strips overhead flickered in uneven intervals, painting the walls in pulses of yellow light and shadow. Somewhere below, men shouted over machinery. Somewhere farther away, armored boots rang against metal decking. The fortress lived around her, unaware that its miracle might be a condemned witch wearing borrowed authority.
She needed to warn Laun.
He was arrogant. Political. Infuriating. But he was still a regimental commander, still the nearest recognizable authority who might understand what it meant for a criminal psyker to hold command inside an isolated stronghold.
She reached Laun's quarters and pushed through the door without knocking.
The room was empty.
The cot was untouched. His travel case sat open. A half-folded cloak lay across a chair. A cup stood on the table, faint traces of clear wine catching the lumen glow.
"Laun already left."
The voice behind her was low, rough, and close enough to make her spin.
Grot stood in the corridor, broad enough in power armor to fill most of the doorway. The old veteran looked down at her with a face that had been carved by war, ration shortages, old scars, and an endless lack of patience. His expression held neither concern nor surprise. Only duty, and a blunt contempt for panic.
Riley forced herself not to step back.
"Where did he go?"
"With Grey." Grot's eyes narrowed. "If you have urgent business, report it to Qin Mo."
Riley's throat tightened. Report it to Qin Mo.
Tell the suspected unsanctioned psyker that she had discovered he was an unsanctioned psyker. Excellent, perhaps afterward she could throw herself into a promethium fire and save time.
She took one step backward.
"I'll find Commander Laun myself."
"Why not tell Laun in person?"
The new voice came from behind her. Smooth. Quiet. Close enough that she knew he had been there before she heard him.
Riley froze.
Her fingers twitched toward her pistol and stopped. There was no point. More than that, he would notice. He had probably already noticed everything.
She turned slowly.
Qin Mo stood in the corridor with his helmet removed, the dim light catching the calm planes of his face. He wore a faint smile, disarming at first glance and deeply unpleasant once she realized there was no surprise in it. No confusion. No question about why she had run here.
He knew.
Of course he knew.
Grot said nothing. The old veteran simply watched, a wall of armor and muscle behind her.
Qin Mo extended one hand with polite, almost courtly ease.
"Come with me, miss."
