War is the only constant in this universe.
On Terra, the siege of Forge World Shana had lasted one full month.
From orbit, Rangdan bombardment fell like a burning storm — incandescent shells screaming through the upper atmosphere, turning the heavens crimson.
Only the void shields kept the world from becoming a furnace.
Without them, Shana would already be ash.
Beneath the shimmering barrier dome, tens of thousands of Astartes fought beside millions of Mechanicum servitors, skitarii cohorts, and indentured labor thralls.
They battled an enemy that never stopped coming.
"Breakout."
Alex issued the order calmly.
Inside his hearts, fury burned like promethium.
The enemy surged forward in endless waves — a writhing sea of bodies.
Among them were human faces.
Imperial citizens.
Now fitted with neural collars and pain governors, driven into a frenzy of violence.
They clawed and bit at everything.
They did not scream.
They did not plead.
They simply attacked.
The slave hordes were weak.
Individually meaningless.
But they were endless.
Every minute, drop-vessels descended through the shield aperture corridors, vomiting fresh waves of expendable bodies onto the killing fields.
Alex knew the truth.
They were not meant to win.
They were meant to endure.
Behind them lay the manufactoria complex — plasma refineries, shell foundries, reactor cores.
If it fell, the defense of Shana would collapse.
If Shana fell, Imperial operations across the sector would collapse with it.
"Sir, northern manufactorum breach confirmed."
Alex's jaw tightened.
Too fast.
Far too fast.
"Where are the Nineteenth Legion elements?"
"Contact lost, sir."
Alex nearly cursed aloud.
Raven Guard operating as mobile raiders — perfect.
Leaving us in a static defense.
Perfect.
He looked skyward.
Through the translucent shimmer of the void shield he could see the silhouettes of massive black warships hanging in low orbit, methodically bombarding the surface.
Recon teams had found no command nodes.
No ground command.
No identifiable leadership.
The real enemy watched from above.
Any attempt to breach the shield perimeter would be annihilated by orbital fire.
"…Sir?"
Alex blinked.
One of the warships had just exploded.
Not damaged.
Destroyed.
Its shattered hull fell like burning meteors through the atmosphere.
Alex roared:
"FOR THE EMPEROR!"
Reinforcements had arrived.
The Rangdan formation shifted with unsettling precision.
Units disengaged.
Orbital spacing altered.
Fire patterns recalibrated.
They had anticipated reinforcement vectors.
From the void emerged a new armada.
At its spearhead sailed the Imperial Wing, its prow weapons still glowing white-hot from recent discharge.
Behind it came hundreds of escorts, Mechanicum warships, and battle barges bearing the sigils of multiple Legions.
The Imperial Wing was not the largest vessel in the fleet.
It was not the fastest.
But it was unquestionably the most dangerous.
During its construction, Yuki had insisted on integrating experimental and forbidden weapons recovered from ancient Terran arsenals. The Emperor, ignoring Mechanicum objections, allowed it.
Now it stood as the Imperium's most heavily armed warship short of the Emperor's own flagship.
Energy gathered at its forward weapon array.
A star was being born.
A pillar of incandescent annihilation erupted forward, carving a path through space.
Rangdan escorts along its trajectory vanished, shields collapsing as if made of paper.
The beam struck the central command vessel.
Its shields flared—
—and held.
Yuki was not surprised.
If the Rangdan were easily broken, she would not have come herself.
Each of seven Legions had dispatched elite detachments to reinforce the Second Legion spearhead, but their arrival would take time.
Time was what Shana did not have.
Yuki had come to buy it.
Inside the Imperial Wing, red-robed tech-priests chanted binary canticles as macrocannons thundered in synchronized volleys.
Void combat raged.
Escort ships detonated like brief stars.
Tens of thousands of lives vanished in moments.
Then another fleet translated into realspace behind the Rangdan formation.
At its head: the Radiance of Macragge.
"Guilliman," Yuki said calmly, "the void battle is yours."
"Understood."
She deferred without hesitation. In fleet warfare and operational geometry, none surpassed him.
She turned toward the drop-bays.
She would handle what she did best.
Surface — Shana
"Break through. Board. Reinforce ground forces."
"Yes, sir."
Drop pods screamed through the atmosphere like falling meteors.
Alex stared upward in disbelief.
Zero Legion markings.
The Vice-Emperor's own forces.
But what truly stole his breath was the figure descending amid lightning.
For a moment he nearly knelt.
It felt like standing before a star.
"Report," she said.
He forced composure.
"We hold the forge complex and shield generators. Enemy numbers remain overwhelming. Shield integrity approaching overload."
"That will not occur," Yuki replied calmly. "You have done well. Victory is imminent. Your service will be remembered."
Then she ascended into the air.
Twin blades flashed.
White lightning erupted.
The enemy ranks disintegrated.
She felt sorrow.
Many souls falling beneath her blades were human.
There was no salvation left for them.
Only mercy.
She granted it swiftly.
The Primarch's presence transformed the battlefield.
Numerical superiority ceased to matter.
The slave tide broke.
Behind her, the Demon Slayer Guard drove forward like a spearpoint while Astartes forces widened the breach.
Explosions rippled across the battlefield.
White flame rolled like a living sea.
Rangdan bio-augmented warriors — towering, shielded, monstrous — fell beneath coordinated Astartes fire and psychic conflagration.
They did not feel pain.
But they still fell.
The Rangdan began withdrawing.
Orbital signatures shifted.
Ships disengaged.
By the time the final Rangdan warrior fell beneath Yuki's blade, the enemy fleet was already accelerating away from Shana.
The siege was broken.
For now.
Radiance of Macragge
Guilliman exhaled slowly.
From the opening moments he had coordinated the entire void engagement — vector prediction, counter-encirclement, kill-zone construction, and reinforcement timing.
Even for him, the cognitive load had been immense.
He allowed himself a faint smile.
Had administrative work dulled his edge?
"Father…?" one Ultramarine asked cautiously.
They had fought with exceptional ferocity, eager to prove themselves under his direct command.
He saw the uncertainty in their eyes.
He smiled warmly.
"You fought with discipline and courage. Even without me, you have become exemplary warriors of the Imperium. I am proud of you."
Relief and pride rippled through them.
Then a voice echoed across the bridge.
Clear.
Impossible.
"Celebrate your victory, humans.
It will make defeat more exquisite."
Guilliman's smile vanished.
They had breached the command network of a Glory-class flagship.
That should have been impossible.
He felt a rare gratitude for the Imperium's partially archaic machine systems. A fully integrated noospheric network would have made such intrusion catastrophic.
The bridge doors opened.
Yuki entered, armor scorched, followed by her guard.
"Casualties?"
"Seventeen escort vessels. Five hundred Astartes. Approximately one hundred thousand auxiliary personnel."
She exhaled slowly.
"Acceptable."
Guilliman nodded. War demanded sacrifice. Victory lay in minimizing it.
She glanced at his wrist.
"You are still wearing the bracelet."
He grimaced slightly.
"…Is there something you intend to tell my mother?"
Yuki blinked.
The dark blue bracelet was her gift — a transmission relay allowing delayed video exchange across warp distances. Guilliman used it to send recordings to his mother on Macragge.
"Do not remove it," she said quietly.
He never had.
Then—
she was gone.
One moment she stood beside him.
The next—
absence.
Guilliman frowned.
"Gage. What just happened? Time?"
Gage checked his chronometer.
"…Father… we were speaking, and then… four hours passed."
Cold realization crept through Guilliman's thoughts.
"Contact the Imperial Wing. Now."
Her voice came through the channel.
Calm.
"Not an attack, Guilliman. Do not be alarmed."
Silence.
Understanding dawned.
Descriptions of the Rangdan he had studied… no longer aligned.
Details blurred.
Memories shifted.
He felt the absence more than the presence.
A void where certainty should be.
Guilliman spoke quietly:
"…So this is Rangdan."
He stared into the tactical hololith.
"…They do not merely fight."
A pause.
"…they erase."
And somewhere beyond Imperial space, something ancient watched… and waited.
