The ancient void-shield generator tore free from its foundations with a sound like splitting mountain-stone. Its rune-etched shell still resonated with residual Warp energy, the symbols along its surface flaring and fading as if some half-dead machine spirit objected to being stolen.
Then argent light speared down through the cavern.
The relic vanished inside the teleportation beam, dragged upward through folded space and returned to the orbital shipyard. The translation did not leave cleanly. Fragments of rockcrete, scorched ferrocrete, and twisted anchor-struts were ripped away in its wake, flung outward in smoking arcs. Where the generator had rested for uncounted years, only a ragged cavity remained, glowing at the edges and venting dust like breath from an opened tomb.
"Time to retreat," Qin Mo commanded.
His voice remained unnaturally calm. Not loud. Not hurried. Just clear enough to cut through the battle-noise behind him.
Beyond the reinforced bulkhead entrance, lasfire howled through smoke. Autoguns barked in frantic bursts. Explosions shook dust from the cavern roof, sending centuries of powdered stone drifting down over armor, corpses, and shattered machinery.
Grey held the line at the entrance, firing as he backpedaled. His weapon snapped from target to target with disciplined economy, each shot buying seconds rather than victory. He did not waste ammunition on bodies already falling. He did not chase kills. He simply denied the enemy a clean path into the chamber until extraction came.
The moment his suppressing fire slackened, the enemy surged forward.
Heretical troops poured into the underground cavern through the bulkhead, stumbling over their own dead in their eagerness to close the distance. Some were soldiers in corrupted PDF armor. Others wore cult vestments over flak plating, their faces marked with the all-seeing sigil of the Lord of Wisdom. They spread out instinctively, trying to encircle Qin Mo and the Thunderborn warriors before the Imperials could withdraw.
One of their officers halted mid-step.
He was a gaunt man wrapped in ornate blasphemous robes, the hems stiff with dust and dried blood. Gold thread formed the eye-symbol of his cult across his chest, though battle smoke had blackened half of it into something closer to a wound than an icon. His gaze swept the chamber once, then fixed on the empty foundation pit.
The relic was gone.
For one long second he did not move. His lips worked silently, shaping denials that never became sound. Cold sweat ran down his forehead and cut clean lines through the grime on his face.
No one in the Talon System had ever truly understood the ancient technology behind the artifact. They had treated it as a sacred inheritance, a miracle of protection, a tool that could be activated, maintained, and feared. They knew how to use it. They knew what rituals, codes, and sacrifices kept it obedient.
They did not know how to replace it.
Now it was in enemy hands.
If the Imperials learned how to deactivate it, the city's shield would fail. If the dimensional anchor collapsed with it…
The officer's hands trembled. Then terror became rage.
"DON'T LET THEM ESCAPE! STOP THEM AT ANY COST, NO MATTER WHAT IT TAKES!"
Only a few soldiers obeyed immediately. Most hesitated. They had seen what the Thunderborn could do. They had watched Qin Mo walk through defenses that should have stopped tanks. No shouted order, no cult oath, and no promise of divine wisdom could make men eager to die in a cavern already lost.
The officer had anticipated cowardice. In his faith, obedience was useful, but fear was more reliable.
A side corridor opened with a grinding shriek. His personal guard emerged in tight formation, grim and expressionless beneath enclosed helmets. Between them hung a quad-barreled heavy stubber mounted on a servo-rig, its ammunition belt dragging across the floor like a metal serpent.
They did not aim at the Imperials.
They opened fire on their own troops.
The heavy stubber's barrels spun into a screaming blur. The first rank of heretical soldiers disappeared beneath the impact. Bodies jerked, folded, and came apart under the merciless hail of rounds. Flak armor shattered. Bone burst. Blood misted into the cavern air and flashed dark beneath the muzzle-flare. Men who had hesitated for half a second were punished as traitors before they could decide whether they still wanted to live.
The sudden slaughter stunned the entire assault.
Then survival instinct took command.
The surviving cult troops broke formation and surged forward, not because they believed victory remained possible, but because the guns behind them were more immediate than the warriors ahead. They scrambled over corpses, shoved one another through smoke, and drove themselves directly into the Thunderborn kill zone.
They were not foolish enough to charge blindly by choice.
They simply had no choice left.
While they died, the traitor officer fled deeper into the tunnels. His face was twisted with fury and humiliation. One hand vanished into his coat and closed around a remote detonator.
He thumbed the activation rune.
Every weapon carried by his own troops began to glow red. Lasguns, autoguns, grenades, power cells, ammunition belts—each flared with a synchronized warning pulse. Some soldiers stared down in horror. Others tried to throw their weapons away.
They were too late.
The cavern detonated in a chain of brutal, overlapping blasts.
Weapons exploded in men's hands. Power packs burst against chests. Ammunition cooked off across the floor. The forced martyrdom tore through the remaining cult troops faster than Imperial fire could have managed. Smoke slammed against the walls. Screams vanished beneath pressure and flame.
The entire sequence had taken less than a minute.
Betrayal was commonplace under the Cult of the Lord of Wisdom. The strong consumed the weak. The clever used the loyal. The useful were spent, and the spent were called blessed.
Even so, betrayal had consequences.
This one produced only carnage and silence.
It achieved nothing.
Qin Mo, Grey, and the Thunderborn had already teleported away.
The officer returned to the cavern only after the detonations ceased. He stood amid charred stone, burning debris, and bodies too ruined to count. The air reeked of promethium, hot blood, cooked flesh, and the bitter mineral stink of melted ferrocrete.
His regiment was dead.
The relic was gone.
The Imperials had escaped without even being forced to fight their way out.
His teeth ground together until pain lanced through his jaw.
"Disgusting. Absolutely disgusting…"
If the Imperials had been forced to exfiltrate on foot, if they had needed to drag the relic through kilometers of tunnel under fire, if they had been bound by the same crude limitations as ordinary soldiers, then perhaps they could have been stopped.
But they had not been.
And now none of that mattered.
....
Aboard the Orbital Shipyard
The relic materialized in the shipyard's secure receiving bay inside a column of silver-white light. The deck trembled beneath its weight as gravity reasserted itself around the ancient machine. Warning runes flashed across nearby cogitator displays. Auspex lenses tracked the fading Warp residue clinging to its shell, then immediately began returning contradictory readings.
Klein stood waiting with a small command staff, several armed guards, and enough caution in his posture to show he had not mistaken "secured" for "safe."
A heartbeat later, Qin Mo and the Thunderborn warriors appeared beside the relic. Their armor smoked from recent battle. Grey's weapon was still raised. Dust and blood had dried across their plates in the patterns of a fight ended too quickly for ceremony.
"What's the current battlefield status?" Qin Mo demanded.
His gaze remained fixed on the artifact. Faint light gathered around his hands as the relic's metal answered his presence with a low, almost subsonic thrum. He barely spared Klein a glance before lifting the generator from the deck as if its immense mass were no more troublesome than a field crate.
The machine's ancient casing groaned under forces no crane had touched. Runes along its surface flashed again, then dimmed.
Before Qin Mo carried it away, he needed the war.
"As per your orders, all Legion regiments have been deployed near the smaller cities. However, you and the Thunderborn returned far faster than expected. They are likely just beginning their offensives now," Klein reported.
"Good. No unexpected developments," Qin Mo nodded.
Everything was proceeding according to the plan. The enemy had relied too heavily on a single ancient defense, and now that defense sat in Qin Mo's hands.
This war had been one-sided from the start. The only question was how much time, ammunition, and collateral damage victory would demand.
"I'm leaving this to you for now. I need to study this relic and determine how to disable the void shield."
Klein gave one curt nod. He did not ask whether Qin Mo needed assistance. He had learned the difference between useful help and standing too close to a miracle with no manual.
Qin Mo carried the artifact into a secure research chamber adjacent to the war room. The doors sealed behind him in layers: plasteel, void-hardened alloy, gravitic locks, and a final containment field that shimmered once before becoming invisible.
Inside the research vault, silence settled quickly.
Not true silence. The shipyard was too large and too alive for that. Power conduits hummed behind the walls. Distant machinery vibrated through the deck. Coolant systems whispered through armored pipes. But compared to the cavern, compared to the battlefield, compared to the desperate roar of men trying to stop the inevitable, the chamber felt almost peaceful.
Qin Mo set the relic down at the center of the vault and circled it once.
He already understood its broad function. The device projected and maintained the capital city's void shield, but that description was incomplete. It did more than block incoming fire. It anchored the city into a folded dimensional state, placing the protected space slightly aside from ordinary reality while keeping it accessible to those inside. An inside-out fortress. A city hidden behind its own translated boundary.
Now he needed to learn how to shut it down without wasting time brute-forcing a solution.
That was not difficult in principle. If necessary, he could build a replacement void-shield system from scratch. It would take resources, fabrication capacity, calibration time, and the irritating task of explaining to officers why a machine that would make a Forge World magos weep had been assembled beside an ammunition depot.
Reverse-engineering the relic was faster.
Qin Mo raised one hand.
The artifact unfolded to his senses. Not physically at first, but structurally. Layers of alloy, hidden mechanisms, impossible tolerances, dormant pathways, and nonstandard energy channels revealed themselves as his will moved through the machine. To a mortal engineer, the relic would have been a sealed mystery. To him, it was a problem with material, function, and intent.
He examined everything.
The casing. The internal lattice. The self-repairing alloy. The dimensional focusing vanes buried beneath the outer shell. The energy conversion matrix. The control pathways that did not connect to any visible interface.
Then he found the power source.
The relic drew directly from the Warp.
That explained the lack of visible power conduits. It had never needed them. Instead, the machine extracted raw energy from the Immaterium and forced it through stabilizing architecture, converting impossible turbulence into a defensive field precise enough to shelter an entire hive city.
Qin Mo's expression tightened.
It was dangerous, but not crude. Whoever built this had not been some chanting fool wiring a daemon into a generator. The design was disciplined. Purposeful. Redundant in all the right places. It treated the Warp as a hostile ocean to be tapped through armored valves, not worshiped, trusted, or invited inside.
The dimensional technology, by comparison, was less advanced than he expected. Elegant rather than baroque. Limited rather than omnipotent. Its true strength lay in survivability. Every function overlapped. Every essential system possessed a fallback. Every failure mode was designed to collapse inward rather than expose the city immediately.
But the more Qin Mo studied it, the clearer the truth became.
It was not merely a shield.
It could also be a weapon.
For anyone else, controlling that function would have been impossible. The relic had no external interface, no control panel, no exposed command port, no standard machine-language receptor, and no convenient rune marked "turn this off." That absence was not decay. It was intentional.
The original builders had designed it so that no matter who captured the relic, it would continue to function only as a defensive measure. Possession alone meant nothing. Knowledge meant little more.
If the Adeptus Mechanicus had recovered it, they could have catalogued its materials, measured its energy emissions, recited binharic prayers over its casing, and written ten thousand pages of commentary on the sanctity of its sealed architecture. They still would not have controlled it.
Destroying it would have been almost as difficult.
The alloy was unknown, though not indestructible. Its strength was not the issue. Its memory was. Every scratch healed within moments. Every deformation corrected itself. The material behaved as if it remembered its intended shape and considered damage a temporary disagreement.
For a Tech-Priest, this would have been a sacred puzzle, an unsolved relic to be guarded, worshiped, and argued over for centuries.
For Qin Mo, it was merely inconvenient.
He activated the ability he had named the Forge of Creation.
The title still felt faintly ridiculous in private, but it served a purpose. Names helped the human mind handle forces that had no interest in human categories. The power answered him cleanly. Matter loosened beneath his attention. Structure became negotiable. Function became something he could rewrite instead of merely observe.
His fingers moved through the air, not touching the relic, but guiding invisible threads of force and intent. Control pathways unfolded, broke apart, and reformed. Security logic that had never known a hand, voice, or command rune was given one. Defensive restrictions were preserved where useful and bypassed where necessary.
Then Qin Mo severed the Warp-based energy supply.
He did it carefully. Not with disgust, not with superstition, but with the practical caution of someone removing a live plasma conduit from a crowded ship. The Immaterium feed snapped shut layer by layer, each valve replaced by a stable, self-contained power architecture of his own design.
The relic shuddered once.
Then it obeyed.
Now the void shield could be turned off.
There was only one consequence.
The shield and the dimensional anchor were not separate systems. They were intertwined. To deactivate one was to collapse the other. The city was not merely protected by the field. It was held in its translated state by the same system that kept the shield alive.
Switching it off would unfasten the capital from the strange half-step reality in which it had been anchored.
Practically speaking, it would erase a hive city.
Qin Mo stood over the relic and considered the matter.
Was the capital city of Talon II important enough to preserve? Could it be retaken intact? Could it be rebuilt later if needed? Was there anything within it worth the time, lives, and strategic delay required to save it from the consequences of the very defense its rulers had trusted?
The answer formed without drama.
The city was not worth saving.
So he shut the relic down.
....
On Talon II, the capital city vanished.
There was no explosion. No pillar of fire. No dramatic collapse of towers into dust. One moment the hive city existed beneath its immense shield, a continent of spires, hive-stack tiers, hab-blocks, manufactoria, market warrens, shrines, armored causeways, and sealed noble districts.
The next moment, it did not.
The dimensional anchor failed, and the city's translated space lost its hold on reality. Its boundary folded inward. The shield collapsed with it. Matter, structure, atmosphere, heat, sound, and every hidden chamber within the protected zone were pulled out of the universe as cleanly as a line removed from a ledger.
Every warship crew conducting orbital bombardment saw it happen.
Officers froze at their auspex stations. Gunnery crews stared through reinforced viewports. Servitors continued cycling targeting data for several seconds before their cogitators registered that the target no longer existed.
Men blinked.
When their eyes opened again, the massive hive city that had once dominated Talon II's surface was gone.
In its place stretched barren wasteland. Rock. Dust. Old impact scars. Terrain that looked as if no city had ever been built there at all. No rubble field. No ruins. No burning districts. No collapsed spires reaching from the ground like broken teeth.
Nothing.
The artifact had not merely shielded the city.
It had held the city apart from reality.
And, in the hands of someone capable of rewriting its controls, it could remove that city from existence altogether.
....
Inside the research vault, the relic cooled beneath Qin Mo's hands.
Its rune-etched shell no longer pulsed with Warp-fed light. The surface had gone dull and cold, reduced from sacred mystery to captured mechanism. Yet Qin Mo regarded it with more interest now than before. A void-shield generator could be built. A dimensional anchor could be improved. But a tool that could displace, preserve, weaponize, and erase at hive-city scale was something worth studying carefully.
He felt neither triumph nor regret.
Only the practical certainty that the battlefield had been simplified, the enemy's greatest defense had been removed, and the world had been better arranged for the plans he intended to carry out.
