"What are you talking about? Who is the Deceiver?"
Qin Mo's words made the Shapeshifter pause.
Its face, which had never settled into one shape for more than a heartbeat, rippled like disturbed mercury. Features rose, sank, and reformed across its skull: a woman's brow, a child's mouth, a corpse's jaw, eyes like molten gold and then black glass. For the first time since the conversation had begun, the creature did not answer immediately.
It hesitated.
Qin Mo had expected denial. He had expected anger. He had expected some elaborate lie wrapped in theatrical contempt, the sort of performance ancient cosmic predators seemed to consider conversation.
He had not expected ignorance.
That doesn't prove its innocence, he thought.
Nor does it prove anything it said before was true. But no C'tan should be unaware of Mephet'ran.
The Deceiver.
The cosmic liar whose name had survived in broken chronicles, xenos records, and the kind of lore Qin Mo had once treated as entertainment before waking inside a universe that made every footnote lethal. The trickster who had whispered promises to the Necrontyr, who had played upon the Silent King's desperation, hatred, and fear of extinction until biotransference seemed not like damnation, but salvation.
Mephet'ran had helped sell an entire species the dream of immortality, and the price had been their souls.
If half the legends were true, it had not stopped there. It had lied to kings, gods, dynasties, and its own kind. It had turned hunger into strategy and betrayal into art. Among beings that devoured stars, it had found ways to make treachery more dangerous than gravity.
A creature so cunning that, in the end, its finest deception might have been deceiving itself.
Qin Mo narrowed his eyes.
If this Shapeshifter was not Mephet'ran, then perhaps it was a shard, a splinter, a remnant with memories cracked by aeons of isolation. Perhaps it had once known the Deceiver and forgotten. Perhaps it had been broken so thoroughly that even its own nature had become foreign to it.
Or perhaps this was simply another layer of performance.
With the C'tan, both possibilities were dangerous.
The Shapeshifter's form steadied at last. Its liquid outline contracted into something roughly humanoid: too tall, too smooth, and too polished to be mistaken for human, but stable enough to suggest deliberate restraint. It raised two fingers.
"I will give you two hints."
Qin Mo remained still. "Go on."
"First, your power is returning." The Shapeshifter's voice had lost some of its earlier playfulness. "The longer you wait, the stronger you will become."
Qin Mo's expression did not change.
That was not news. Not exactly. He had felt it already in the slow widening of his senses, in the ease with which matter answered him now compared to his first days in the Underhive. What had once required effort had become instinct. What had once required rage had become technique.
Still, hearing another entity say it aloud carried weight.
"And the second?"
"Second," the Shapeshifter said, its glowing eyes sharpening, "do not think killing those wretched bugs means the war is over."
"Explain."
Qin Mo did not trust it. He would have trusted a malfunctioning plasma reactor more readily. But information did not need to be honest to be useful. Even a lie revealed the liar's priorities if examined from the right angle.
The Shapeshifter's voice distorted. Several tones overlapped at once: male, female, old, young, whispering, laughing, speaking from far away and too close at the same time. It sounded less like madness than damaged transmission, as if a thousand dead civilizations had left echoes inside its throat.
Yet its words were clear.
"Your planet is being corrupted. You and the Genestealers are merely pieces on a larger board."
Qin Mo's gaze hardened.
The Shapeshifter continued. "My foresight is limited, but I must warn you. The first person you see when you leave the Underhive…"
It leaned closer.
"That man worships a False God in the Sea of Souls."
Qin Mo exhaled slowly.
A prophecy. Or a manipulation. Or both. In this galaxy, the difference between warning and trap often depended on who survived long enough to write the report.
He had little patience for cryptic revelations, especially from entities that treated clarity as a personal weakness. Eldar Farseers loved half-truths. Daemons loved riddles. Ancient gods loved declaring that everything was inevitable after pushing the first stone themselves.
But this was, by the standards of supernatural interference, almost direct.
"I appreciate the warning," Qin Mo said. "Though at this point, it is less of a warning and more of a disclosure."
His tone remained calm. Dry, even.
"I'll take it into consideration."
The Shapeshifter studied him as if waiting for fear to appear.
It did not.
"You will see that I was right," it said.
Then its expression shifted again, softening into something almost persuasive. The change was too smooth to be sincere.
"I can help you become the ruler of these humans. Their leader. Their master. Their god in all but name."
Qin Mo said nothing.
The Shapeshifter lowered its voice.
"But you must atone for your past betrayal."
It searched his face.
Looking for guilt.
It found none.
Qin Mo smiled faintly and tapped one finger against his temple.
"You do realize my mind is still human, right?"
The Shapeshifter nodded once.
"Then why the hell would I atone?"
The words landed with quiet amusement rather than anger. Qin Mo tilted his head, watching the creature's reaction with clinical interest.
"I never built weapons for the Necrons. I never aided the Silent King. I never dragged an ancient species into biotransference. I never betrayed your kind, if that's what this is about."
His smile sharpened.
"So why should I feel guilty for something I never did?"
The Shapeshifter's face spasmed. Its borrowed features split and overlapped, grief and rage and confusion flickering across them in quick succession.
"No…" it whispered. "No, no, no…"
Its body trembled, edges fraying into light.
"This… this is not how it is supposed to be…"
Qin Mo raised a hand in a lazy farewell.
"Goodbye."
The Shapeshifter's eyes snapped back to him.
"Next time you invade my mind," Qin Mo said, "at least announce yourself first."
Then he tore himself from the dream.
....
Qin Mo's eyes opened.
For several seconds he did not move. He lay staring at the wall of his chamber, listening to the low hum of the fortress around him: distant machinery, airflow through reinforced vents, boots passing somewhere beyond the door, the soft vibration of power systems built by his own hand.
His pulse was steady.
His thoughts were sharp.
The dream did not fade like ordinary sleep. It remained intact, each sentence preserved with unpleasant clarity. The Shapeshifter's ignorance. Its hints. Its warning about the first man he would see outside the Underhive. Its demand for atonement.
Had he been too blunt?
Perhaps.
But bluntness had its uses. Cosmic entities expected awe, terror, bargaining, reverence, or hatred. They knew how to shape those reactions. Qin Mo had no desire to give any ancient predator a familiar handle on his mind.
In the grim darkness of the far future, gods were rarely benevolent.
Some demanded worship. Some demanded blood. Some demanded obedience. Some merely smiled and waited for mortals to call the trap a blessing.
Whether the Shapeshifter was a shard of the Deceiver, a different C'tan remnant, or something wearing the idea of one, its words could not be trusted cleanly. But they could not be ignored either.
That was the irritating part.
A sharp knock struck the door.
"Knock. Knock. Knock∼"
Qin Mo turned his head.
The door opened only a crack at first. Klein peered in with the caution of a man who had learned not to interrupt Qin Mo during research unless the matter was important, urgent, or both. When he saw Qin Mo awake and not surrounded by floating machinery, molten metal, or half-assembled weapons, he stepped inside.
"What is it?" Qin Mo asked.
Klein carried a rolled schematic beneath one arm. His uniform was clean by Underhive standards, which meant only that the blood on it was old and the ash had been brushed off recently. His face carried the controlled fatigue of a commander who had slept just enough to remain functional and not enough to stop looking dead.
"I want to inspect the passage leading into the lower hive," Klein said. He unrolled the schematic across the nearest worktable and pinned its corners with spent power cells. "The excavation crews reached the primary obstruction. Anruida says you should see it yourself."
Qin Mo glanced at the blueprint. The old ascent route stretched across the parchment in layered lines, half accurate engineering record and half guesswork filled in by drone scans.
"Of course," he said.
Klein studied him for a moment. "Were you sleeping?"
"Briefly."
"Properly?"
"No."
Klein sighed, but did not waste breath on protest. In the Underhive, everyone had developed a practical relationship with exhaustion. If a man was upright, coherent, and not hallucinating enemies in the walls, he was considered fit for duty.
Qin Mo rose and reached for his armor.
....
The transport gunship descended through the polluted air in a controlled spiral.
Its engines beat dust outward from the landing zone before the landing struts touched down. Ground crews in patched flak armor guided it in with signal wands while drones hovered overhead, scanning for structural weakness, hidden movement, and the kind of last-second sabotage the Underhive specialized in.
The Genestealer war was nearly concluded, at least in its open form. The cult's main command structure had been shattered. Its Patriarch was dead. Its larger concentrations had been broken, burned, or scattered. That did not mean the danger had ended. It meant the war had changed shape again.
Now came pursuit.
Now came clearance.
Now came the slow, filthy work of finding hidden brood cells, collapsing supply tunnels, identifying compromised officials, and proving that no surviving cult magus had enough influence left to ignite another district.
A full regiment had been deployed to secure the passage entrance. Defensive lines surrounded the area in concentric layers: infantry trenches, drone patrol routes, vehicle barriers, auspex posts, kill zones, ammunition caches, medicae stations, and artillery positions ready to flatten anything that crawled out of the dark without permission.
Qin Mo and Klein stepped off the gunship together.
They passed the ruins of an old fortress on the way to the checkpoint.
The remains stood like a broken tooth jutting from the Underhive floor. Battered walls leaned beneath layers of soot and impact scars. Old firing slits had been warped by heat. Collapsed barricades still marked the approaches. Here and there, newer support frames held up sections that should have fallen weeks ago.
The 44th Regiment's stronghold.
Once, Qin Mo and Grey had defended it.
Once, men had died here by the dozens because there had been nowhere else to stand.
Now the place was empty except for survey markers, hazard lights, and the ghosts of habits no one had time to mourn.
Klein slowed. "This place was supposed to be demolished."
Qin Mo looked at the ruins without expression.
"But since you fought here as a soldier," Klein continued, "some of the officers suggested preserving it. A memorial, perhaps. Or a monument. They think it should remain standing forever."
"Tear it down," Qin Mo said.
Klein glanced at him.
Qin Mo's voice remained flat. "I hold no attachment to this place."
To him, the 44th Regiment was not a banner worth preserving. It was a penal unit, a cage with lasguns nearby, a place of beatings, humiliation, forced labor, and men treated as already dead because a number had been stamped onto their lives.
Some good men had survived it. Many better men had not.
That did not make the prison sacred.
Klein accepted the answer with a slow nod. After a moment, he let out a dry breath that might have become a laugh under kinder circumstances.
"I went to the academy with Burr," he said. "What was your opinion of him?"
"An idiot."
The answer came so quickly that Klein almost smiled.
"Only the most forsaken souls in the Imperium would end up serving under him," Qin Mo added.
This time Klein did chuckle, quietly and without joy.
"That is unfair," he said. "Some of us were forsaken before we ever met him."
Qin Mo gave him a sidelong look.
Klein's expression softened by a fraction, then hardened again as they approached the main checkpoint. "For what it is worth, Burr was always like that. Loud, cruel, convinced that fear and discipline were the same thing."
"They are not."
"No," Klein agreed. "They are not."
The checkpoint swallowed them a moment later.
It was less a gate than an artificial canyon, a colossal corridor built into the hive's ancient bones. Four regiments could have marched through it shoulder to shoulder with room left for supply crawlers along the flanks. Its walls rose into shadow, reinforced with adamantium plating old enough that even corrosion seemed to have given up halfway through its work. Each slab bore faded forge marks, serial prayers, and manufactorum sigils worn almost smooth by age, dust, and neglect.
The air inside was cooler than the landing zone, but heavier. It smelled of dust, machine oil, dry rust, and old electrical insulation. Qin Mo could feel dormant systems beneath the surface: conduits that had not carried full power in centuries, stabilizers sealed behind wall panels, support mechanisms built for loads far beyond ordinary traffic.
This passage had not been constructed merely for pilgrims, workers, or cargo lifts.
It had once served something larger.
Dormant lum-globes lined the vaulted ceiling. Some flickered as their circuits accepted newly restored power; others remained dead, black glass eyes staring down at the rail system laid through the center of the corridor.
The rails were new.
Logistics drones had built them in straight, practical lines over the ancient floor, welding track into reinforced anchor points and laying power conduits along the sides. Waiting train cars rested on the line, each broad enough to carry Leman Russ battle tanks, artillery platforms, or bulk crates stacked three men high. Servo-couplers clicked as drones inspected the suspension systems.
Klein followed Qin Mo's gaze. "Your drones work quickly."
"They follow instructions and do not argue with basic logistics."
"A rare virtue."
"In the Imperium, yes."
Klein did not dispute that.
Eventually they would have to ascend into the lower hive. Not as fugitives crawling toward daylight, but as an organized force with armor, ammunition, medicae support, food, repair capacity, and enough firepower to make any compromised official regret surviving the Genestealer purge.
Logistics mattered.
An army did not climb out of hell on courage. It climbed on supply lines.
The railcar carried them deeper into the passage. Ten kilometers of reinforced corridor passed by in a rhythm of metal joints, flickering lumen strips, and drone work crews cutting away debris from side galleries. Troopers stood guard at intervals, their Praetorian armor sealed, weapons angled downward but ready. Many saluted as Qin Mo and Klein passed. Others simply stared, then remembered themselves too late.
Qin Mo ignored both reactions.
At the end of the line, the corridor widened again.
A figure in Thunderborn-pattern power armor waited beneath a temporary floodlight. His armor was marked not by excessive battle damage, but by small practical modifications: data ports added near the gauntlets, extra storage compartments, reinforced sensor housings, and purity seals placed by others rather than by his own enthusiasm.
Anruida.
Unlike Grot, who treated battle as a problem best solved through impact, Anruida approached war as a scholar forced to keep a weapon within reach. He was a scribe, archivist, analyst, and reluctant combatant, more comfortable with records than slaughter. That made him useful here. Excavation required patience, documentation, and the ability to notice when ancient engineering did not match any sane expectation.
He saluted Qin Mo, then Klein.
"Lord Commander. Commander Klein."
"Report," Qin Mo said.
Anruida turned and gestured toward the obstruction ahead. "As you can see, clearing this passage will not be simple."
Qin Mo looked up.
The tunnel ahead was sealed.
Not blocked by a cave-in. Not choked by rubble. Sealed.
A titanic barrier filled the entire passage from floor to ceiling, its surface disappearing into darkness above and stretching beyond the floodlights to either side. The structure was immense even by hive standards: two kilometers high, seven kilometers wide, a wall of ancient material layered so densely that the excavation drones' scans showed only partial penetration.
Its surface was not smooth. Reinforcement bands crossed it in geometric patterns, each wider than a roadway. Locking structures the size of hab-blocks had been fused into the frame. Some bore the marks of Imperial maintenance. Others were older, stranger, and so worn that their original purpose had become guesswork.
Klein stepped forward, schematic in hand, and stared up at the barrier with visible awe.
"Ancient engineering is incredible," he said quietly. "We do not even know why they built such a massive passage."
Anruida's helm turned toward Qin Mo. "The drones have identified several embedded mechanisms, but most are inactive or inaccessible. This may once have been a gate. Or a blast door. Or a containment barrier."
"Or all three," Klein muttered.
Qin Mo did not answer immediately. His attention moved across the sealed structure, reading stress lines, material density, old weld patterns, impact scars, and construction logic. He imagined the forces required to justify such scale. The cargo that might have moved through here. The machines that might have needed seven kilometers of clearance.
His eyes darkened.
"Thousands of years ago," he said, "maybe tens of thousands…"
Klein and Anruida both looked at him.
Qin Mo kept his gaze fixed on the ancient barrier.
"The lower hive may have been a weapons factory."
His voice remained calm, but the words made the huge corridor feel colder.
"One capable of producing war machines beyond your understanding."
