As Qin Mo and his warriors advanced through the ruined streets of Kato, the column grew around them.
Militia fighters moved along the flanks in loose clusters, weapons held low but ready, their eyes constantly checking windows, rooflines, and alleys clogged with smoke. PDF soldiers marched closer to the center, more disciplined in formation despite their exhaustion. Some still wore intact flak armor. Others had stripped plates from the dead and tied them over wounds with torn webbing. Every step made spent casings crunch beneath their boots.
Kato itself looked less like a settlement now than a city that had survived being murdered halfway. Fires smoldered inside bombed-out habs. Smoke leaked from shattered ventilation stacks. Somewhere beneath the street, damaged pipes knocked and hissed, spilling steam through cracks in the ferrocrete. The air stank of ash, promethium, blood, burned insulation, and the sour chemical damp of the Underhive.
More survivors emerged as the column passed a bombed-out cathedral.
The building had once been an Imperial shrine, though only its bones remained. The front doors had been blasted off their hinges. One tower had collapsed through the roof, crushing pews and leaving broken statues half-buried beneath rubble. The Emperor's face still looked down from the cracked mural above the nave, one golden eye blackened by soot, the other reflecting the fires outside.
The people sheltering inside came out slowly. Refugees first: gaunt, dust-covered civilians who had spent too long hiding in the dark, clutching bundles, children, water tins, or whatever else they had refused to abandon. Many were wounded. Some limped. Some were carried between two others. A few walked without seeming to notice the blood running down their sleeves. All wore the same hollow look Qin Mo had seen too often in the Underhive: the expression of people who had watched authority fail, walls break, and neighbors die, and had not yet decided whether survival was mercy or simply delay.
But two figures stood out.
One was a middle-aged man in a torn but high-quality officer's coat, its collar marked with the rank insignia of a Regimental Commander. The cut of the uniform, the polished signet ring on one gloved hand, and the faintly offended set of his mouth all marked him as Upper Hive stock even before anyone named him. He was too clean compared to the men around him. Not untouched by the battle, no one in Kato was untouched, but clean in the way of someone who had spent the worst of the fighting behind stone walls rather than in the street.
The other was a woman in a severe official uniform, dark hair bound tight, posture straight despite the dust on her coat. Her eyes moved constantly, not like a frightened civilian searching for danger, but like a clerk counting evidence and a predator measuring distance. An Arbites badge hung at her chest, half-hidden beneath a torn outer layer of protective fabric.
The PDF officer who had fought alongside Qin Mo earlier stepped forward, his voice tight with the effort of observing proper protocol in a place that had already devoured most forms of order.
"Regimental Commander Laun of the Logistics Corps."
He gestured to the woman.
"And this is Riley, an agent of the Hive's Arbites Division."
Qin Mo was not surprised by Laun's survival.
The PDF had been scattered across the Underhive since the offensive collapsed. A logistics commander was exactly the sort of senior officer who might survive disaster: important enough to have escorts, removed enough from the front line to avoid the first wave of casualties, and politically useful enough that someone would drag him into shelter before the shells landed.
But an Arbites intelligence officer? Here?
That was different.
The Adeptus Arbites rarely concerned themselves with the Underhive unless something had gone badly wrong by Imperial standards, which meant much worse than gangs, riots, extortion, murder, smuggling, or local corruption. Those were problems for planetary authorities, militia, enforcers, or whoever had enough guns and ambition to pretend they represented the law.
The Arbites were not simple police. They were the mailed fist of Imperial Law: judge, jury, and executioner, trained to answer not to a hive governor's convenience but to the Lex Imperialis itself. When they moved in force, it usually meant sedition, tithe fraud, treason, rebellion, or a crime large enough that the Imperium's patience had ended.
So what was Riley doing in Kato?
Had the ruling elite of Tyrone Hive truly sent Arbites assets this deep into the abyss? Had they known more about the rebellion than they had admitted? Or had Riley come here for a reason no one in the PDF had been cleared to know?
Laun stepped closer before Qin Mo could study her further. His eyes settled on Qin Mo's armor with naked curiosity, then shifted to the Aquila-topped staff in his hand. His expression sharpened. Calculation first, politeness second.
"Are you the Marshal's honor guard?" Laun asked. "I've never seen this pattern before."
"We're not part of the Marshal's forces," Qin Mo replied.
Laun's brow creased. The answer displeased him because it created a category he did not control.
"You arrived too late, soldier," he said, irritation bleeding through the noble polish in his voice. "By the Emperor, we've been fighting street to street for nearly a week. Where have you been?"
Grey stood just behind Qin Mo, helmet tucked beneath one arm. His jaw tightened. Soot blackened one cheek, and the look he gave Laun could have cut wire.
"By the Emperor," Grey muttered, not quite quietly enough, "I almost thought this entire force had been led by a mere captain." His voice dripped with sarcasm. "Imagine my relief when the missing command structure finally reveals itself, safe in a cathedral."
Several militia fighters heard him. So did the PDF soldiers nearby. A few lowered their eyes. Others looked directly at Laun, and their expressions did not contain respect.
Grey's meaning was obvious.
While everyone else had been fighting and dying in the streets, Laun and Riley had remained inside the cathedral.
No orders had come from them. No counterattack had been coordinated. No rallying point had been established. Units had fought alone, blind, leaderless, and certain that higher command had either abandoned them or died.
A week of that could rot discipline faster than hunger.
Laun's face darkened. For a moment, Qin Mo saw the impulse behind his eyes: a reprimand, an arrest order, perhaps even a demand that Grey be punished for insolence. Then Laun noticed the soldiers around them. Not just Qin Mo's armored warriors, but the militia, the PDF survivors, the civilians watching from the cathedral steps. Too many witnesses. Too many loaded weapons. Too much resentment.
He swallowed the reaction and changed the subject.
"Are there any higher-ranking officers still alive?"
"No, sir," Qin Mo said.
His reply was calm. Too calm. Almost detached.
Grey stared at him.
From the moment Laun had appeared, Qin Mo had acted naturally, even politely, as if surrendering authority to a man who had spent the battle hiding in a shrine was not absurd. He had even called Laun "sir" without hesitation.
It made no sense.
This was the man who had dragged regiments back from annihilation, built fortresses from ruins, armed soldiers with weapons that should not exist, and held Kato together through sheer force of will and impossible violence. And now he was standing in the street like an obedient subordinate because some noble-born logistics commander had wandered out of a cathedral with rank pins still attached.
What the hell was going on?
Laun, however, saw only compliance. His shoulders eased. His chin lifted. The fear he had hidden behind irritation began to transform into confidence.
"You came late, but you did well, soldier." He stepped forward and clapped one gloved hand against Qin Mo's armored shoulder, as if granting a medal by touch alone. The impact made a dull sound against the warplate. "From now on, you will follow my orders. Understood?"
"Yes, sir."
Qin Mo nodded without hesitation.
Grey's fists clenched at his sides. The servos in his gauntlets gave a faint warning click before he forced his hands open again.
Laun's next words were worse.
"Now take me somewhere safe," he said. "This lady and I require protection."
He gestured toward Riley.
Riley smiled at Qin Mo.
It was not a warm smile. Not gratitude, relief, or even courtly politeness. It was thin, controlled, and watchful, the expression of someone who had found an unexpected variable and was deciding whether it could be used, contained, or condemned.
Grey remembered what she was.
An Arbites officer was not here merely to survive. She was here to judge.
"Understood," Qin Mo said.
He turned to Grey and gave a small hand signal. Summon transport.
Grey wanted to hit him.
He wanted to grab Qin Mo by the collar, armor or no armor, and ask whether he understood what he was doing. Qin Mo was handing over the army he had united through fire, blood, and terrifying competence. He was giving a hollow-eyed noble the chance to claim everything built by men who had actually fought.
But Grey stopped himself.
He had followed Qin Mo through stranger decisions. He had seen plans that looked insane become victory because Qin Mo understood three steps more than anyone else. That did not make this easier. It only made disobedience harder.
Grey activated the vox-unit on his wrist and called in the drone. His movements were stiff. Reluctant. Angry.
Even if he did not understand, he still had faith.
....
Nightfall — The 47th Regiment's Fortress
"Commander!"
The corridor guards snapped to attention as Klein stormed past.
"At ease."
He waved off the salutes without slowing. His boots struck the steel decking in hard, even blows that echoed through the dim corridor like restrained artillery. The fortress around him no longer resembled the hab-block it had once been. Reinforced walls pressed close on either side. Cable channels hummed behind armor plating. Lumen strips burned low to conserve power, leaving the passage in bands of yellow light and shadow. Somewhere below, fabrication machinery growled through the floor. Somewhere above, sentries called position checks over the local vox.
Klein heard none of it clearly. Fury narrowed the world.
He reached Qin Mo's quarters and entered without knocking.
The room had once belonged to some middle-ranking hab administrator, judging by the cracked wall shrine, the built-in desk, and the soot-stained outline where a family portrait had hung before someone used the frame for kindling. Now it served as Qin Mo's workspace. Schematics covered the desk and walls: fortress layouts, drone command architecture, power-armor refinements, casualty projections, salvage tallies, and half-completed weapon designs layered with marks that no sanctioned engineer in the sector would have admitted understanding.
Qin Mo stood at the desk, one hand hovering over a schematic etched with runes, tactical overlays, and structural annotations. He looked up as Klein entered.
Klein raised a hand, cutting him off before he could speak.
"Do you even know what the man you brought back is doing?"
Qin Mo arched an eyebrow. "Laun? What about him?"
Klein laughed once. It was a bitter, humorless sound.
"He's been barking orders at my men. Demanding they clear out the largest room in the fortress for his personal use." Klein's voice hardened with each word. "Then he ordered them to find him the best bed available. When they told him every bed in this fortress is either occupied by wounded men or made from scrap, he told them to commission a custom one."
Qin Mo blinked. "A custom bed?"
"Silken hangings," Klein said. "Heated coils. Privacy screens. A separate wash station if materials allow."
For a moment, Qin Mo simply stared. Then he gave a short snort.
"He actually asked your men to build him a noble's bed in the middle of a siege?"
"Oh, he is not stupid," Klein snapped. "Do not make that mistake."
He stepped closer, lowering his voice. The anger remained, but now it had discipline behind it.
"He is Upper Hive nobility. Men like him do not make stupid mistakes. They make power plays. They do not draw blades when a room, a bed, a title, or a gesture will do the work for them." He pointed toward the corridor. "This is him marking territory. He wants every soldier in this fortress to understand that he expects privilege, obedience, and recognition. He wants them to see him giving orders and see us permitting it."
This was the first time Klein had openly questioned Qin Mo.
Not cautiously. Not indirectly. Not as a subordinate requesting clarification.
Directly.
Because this time, he could not accept what he was seeing.
"Do you understand what happens next?" Klein asked. His voice dropped low. "Your command will be stripped away piece by piece. Your true rank, a common soldier at best, will be exposed the moment he pushes the question hard enough. And the defensive line you built through blood, labor, and impossible work?"
He leaned over the desk.
"It will become someone else's. You will remain a soldier. Perhaps even lower in formal standing than me. Perhaps useful enough to be kept close, dangerous enough to be watched, and politically inconvenient enough to be removed when the fighting ends."
Qin Mo studied him for a few seconds.
Then he asked, "Why?"
Klein froze.
"…What?"
"Why would my army become his?" Qin Mo repeated.
The question was not rhetorical in tone, but it landed like a trap being sprung.
Qin Mo straightened from the desk and began counting on his fingers.
"Can Laun conjure fire and lightning to slaughter the enemy?"
Klein said nothing.
"Can he forge weapons beyond local Imperial understanding?"
Silence.
"Can he rebuild fortresses, deploy drone logistics, manufacture armor, coordinate supply, strike enemy commanders personally, and turn collapsing fronts into defensible positions?"
Klein's expression shifted. Anger did not vanish, but uncertainty entered it.
Qin Mo continued, calm as a man discussing inventory.
"Can he make the soldiers believe he is the reason they are still alive?"
That last question ended the argument more effectively than shouting could have.
Klein looked toward the closed door, then back at Qin Mo. The logic settled in despite his irritation.
Every soldier in the fortress had either witnessed Qin Mo's power firsthand or heard the stories from men who had. The power armor, the drones, the fortified walls, the food, the ammunition, the rescued outposts, the survival of Kato, all of it pointed back to Qin Mo.
More than that, the soldiers believed they had been betrayed by the Upper Hive, abandoned by High Command, and spent like cheap ammunition by men who would never breathe sump-air.
Laun had rank. Qin Mo had results.
In the Underhive, results were becoming a stronger currency.
Unless Laun could bring something greater to the table, his schemes meant very little.
Klein exhaled and rubbed the bridge of his nose. Some of the fury drained from him, leaving exhaustion in its place.
"…Then why bring him here at all?" he asked. "Why not leave him in Kato with the other survivors?"
Qin Mo glanced toward the door. He waited, listening. No footsteps lingered outside. No armor shifted against the wall. No one was close enough to overhear without equipment, and the fortress systems would have noticed that.
Only then did he speak.
"Because I need options."
Klein narrowed his eyes.
Qin Mo leaned back against the desk.
"We have a contingency plan. We dig. We clear the collapsed tunnels, reopen a path toward the Lower Hive, and use Laun and any other nobles we recover as bargaining chips. If the situation becomes unwinnable, we negotiate with High Command for permission to evacuate the surviving forces back upward."
Klein stared at him.
"…Escape?" he said slowly. "You are planning to run?"
The disbelief in his voice was not contempt. It was shock. For days, Qin Mo had seemed like a man who answered every disaster by building something sharper and walking toward the next fire. The idea of him planning retreat felt almost unnatural.
Qin Mo's gaze hardened.
"I said contingency plan. I will do everything possible to achieve victory. I will build, reinforce, rescue, strike, and kill until the enemy breaks or I do."
His voice lowered.
"But if we fail, I will not sit in this fortress and wait for everyone under my command to die because pride sounds better than survival."
Klein held his stare. Slowly, reluctant understanding replaced the last of his outrage.
That was why Qin Mo had accepted Laun so easily. Not submission. Not weakness. Leverage.
Klein nodded once.
"Should I detain him?"
"No."
"Then what?"
"Keep him close," Qin Mo said. "Give him enough comfort to believe he is being respected, enough freedom to reveal what he wants, and enough watchers that he cannot do anything useful without us knowing."
Klein's mouth tightened. "And Riley?"
For the first time, Qin Mo's expression shifted. Barely.
"Watch her too."
Klein heard the difference. "You suspect her?"
"I suspect everyone who appears in the Underhive wearing authority too cleanly." Qin Mo looked back at the schematic. "Find out where Laun's family is. Find out who he served under. Find out why an Arbites intelligence officer was sheltering with him in Kato instead of operating from an Arbites precinct or command bunker."
Klein absorbed that, then gave a sharp nod.
"Understood."
He turned to leave, but stopped at the door.
"Qin Mo."
Qin Mo looked up.
Klein's expression was severe, but the anger had changed into something closer to warning.
"If this is a game, remember that nobles have played it since before either of us were born."
Qin Mo's mouth twitched faintly.
"Then it is fortunate I am not playing by their rules."
Klein left immediately.
The door shut behind him. The room fell quiet except for the low hum of machinery in the walls and the faint scratch of cooling metal somewhere on the desk.
Qin Mo remained still for several seconds.
Everything he had told Klein was useful. Practical. Plausible.
It was also a lie.
If the attack on the Underhive was truly tied to an Upper Hive conspiracy, then Laun's noble status would not save anyone. The same High Command that had sent regiments into a trap would not trade survival for the comfort of one inconvenient aristocrat, not unless pressure was applied in a way they could not ignore.
Qin Mo had no intention of bargaining honestly.
Laun was bait. Cover. Noise. A visible problem to occupy the fortress while Qin Mo studied the quieter threat beside him.
Riley.
An Arbites intelligence officer in the Underhive, smiling like she already knew which verdict she preferred.
Qin Mo turned back to the schematic, but his eyes no longer followed the lines. His thoughts had already moved elsewhere: patrol routes, blind spots, servant details, private interviews, false emergencies, sealed rooms, and all the small ways a dangerous person could be separated from witnesses without anyone noticing until after the fact.
He muttered to himself.
"I'll need to arrange an accident…"
