The Rangdan had learned.
They always learned.
To them, most humans were expendable organisms — suitable for labor, consumption, or conversion into disposable war stock. Even their slave armies, stripped of will and memory, were tools no more valuable than ammunition.
But the Primarchs were different.
They were anomalies.
Predators that could not be assimilated.
Weapons that could not be replicated.
The Rangdan did not understand the Emperor — but they understood this:
if his offspring walked the battlefield, conquest would never be secure.
So they evolved.
The Anti-Primarch Constructs
The new warforms were not soldiers.
They were answers.
Each required grotesque resource expenditure and arcane bio-mechanical grafting.
They possessed little cognition.
No individuality.
No self-preservation instinct.
They existed only to kill.
To neutralize.
To destroy singular targets of overwhelming biological superiority.
They were deployed only once.
And that once was here.
The Canyon of Black Mist
Eusonis watched the canyon fracture under bombardment.
White fire and black fog devoured the sky where Yuki had vanished.
Boulders collapsed. Shockwaves tore through rock walls. The battlefield had become a broken grave.
But even if they found her…
what then?
Many of the defectors today were First Legion veterans — warriors who had fought the first Rangdan war.
Even within the Demon Slayer Guard, corruption had manifested.
How could he guarantee his own loyalty?
How could anyone?
He forced the thought away.
Faith was not certainty.
Faith was choice.
"Break out," Eusonis ordered. "Link with units not yet compromised."
Kadis slammed an attacker aside, teeth clenched.
"Do you intend to abandon her?"
"No."
Eusonis's voice did not waver.
"The Guard and I remain. We reach the Primarch."
White flame flickered in the distance.
Black mist churned like a living storm.
"We will fulfill our duty."
The Heart of the Storm
The sun vanished behind choking black fog.
Lightning flashed in violent bursts beneath a sky the color of bruised flesh.
The ground burned.
White fire crawled across shattered stone like living light.
This was no longer a battlefield.
It was a wound in reality.
Warships emerged from void apertures, disgorging Rangdan reinforcements. Black beams lanced downward, annihilating the last Knight engines defending the canyon rim.
Yet none of it reached the center.
White flame and void mist repelled all intrusion.
Within that hell, Yuki fought.
A voice slithered from the twisted constructs.
"We know your brothers' movements. None come to rescue you. Does that not stir curiosity? How did we—"
Lightning erupted.
Yuki became a streak of descending white fury.
The monsters met her with black-edged blades.
Metal shrieked.
One construct was hurled aside.
The others converged.
Yuki understood.
Individually, they were nothing.
But the fog…
The fog was wrong.
It burned against her skin.
Her aura dimmed.
Her armor's radiance dulled.
Only the Emperor-forged twin blades still shone — simple, indestructible instruments designed not as relics, but as extensions of their wielder.
Because Yuki herself was the true weapon.
She fought without pause.
Sword met blade in thunderous cadence.
She decapitated one construct.
Black mist surged.
The corpse reformed.
Her flames engulfed them.
They tore burning flesh from their bodies and advanced regardless.
Madness.
Endurance.
Absolute annihilation instinct.
Even a Primarch could feel the chill of such relentless purpose.
Yuki inhaled.
The fog burned her lungs.
Blood touched her tongue.
She smiled.
Her violet eyes ignited crimson.
Breaching the Sphere
Eusonis reached the edge of a black hemispheric barrier.
White light flickered weakly within.
Outside, Imperial forces battled renewed Rangdan landings while void war raged overhead.
His gauntlet touched the surface.
Armor plating pitted and corroded instantly.
He inhaled.
"Advance. Rescue the Primarch."
Inside, the Demon Slayer Guard beheld something they would never forget.
Yuki stood amid torn flesh and dissolving black mist.
Her twin swords lay discarded.
Her golden armor shattered.
Corrosive lesions marred her skin.
Blood flowed from nose and mouth with every breath.
And she was killing them.
Not as a warrior.
As a force of nature.
She tore regenerating masses apart with flame-coated hands, shredding them faster than they could reform.
The mist faltered.
Reality began to reassert itself.
Eusonis remembered the day of his appointment.
"You have a special mission," she had told him.
"If I lose control, you will wake me. Or kill me."
He had not asked why.
He did not need to.
All his equipment.
All his training.
All his purpose.
Had been designed for one hypothetical enemy.
Yuki herself.
He approached.
Sword drawn.
The Guard raised their weapons.
"Mother," he said quietly. "It is over."
Her movements slowed.
"No, Eusonis… it has only begun."
The Sky Bleeds
The heavens split.
A blood-red wound tore open across the sky.
Daemons poured through like rain.
A roar shattered the canyon.
A colossal form descended.
Hoofed feet struck the ground with thunder.
Whip in one hand.
Axe in the other.
Khorne's greatest Bloodthirster.
Ka'Bandha.
Yuki rose.
Her wings spread — corroded, torn, yet luminous.
She seized her blades.
"Ka'Bandha," she said, smiling through blood,
"you dare face me again?"
The Bloodthirster laughed.
Behind him, daemonic hosts collided with Imperial and Rangdan forces alike, war dissolving into apocalyptic chaos.
Only the space between the Primarch and the Bloodthirster remained untouched.
"Look at you," Ka'Bandha growled. "You revel in pain. You seek worthy foes. Join the Blood God —"
Her blade nearly removed his head.
He recoiled.
Fire surged toward him.
He leapt through it, flesh screaming as holy flame bit into his form.
Pain fueled his fury.
He descended in a killing strike.
Yuki met him like a storm.
Each blow heavier.
Faster.
More violent.
Blood streaming across her body.
Her strength undiminished.
They fought amid artillery strikes and collapsing stone, unmoved by the apocalypse around them.
"You are wounded," Ka'Bandha snarled. "Stronger, yes — but not invincible."
Her blade flew from her right hand.
Her body opened to fresh wounds.
Her left blade drove toward his heart.
He hurled her away.
He seized her throat.
Wings spread.
The portal yawned above.
She laughed.
Clear.
Soft.
Terrible.
Her hand plunged into her own chest.
She tore free a radiant rib of white-gold light.
A relic of impossible sanctity.
She drove it through his chest.
Ka'Bandha screamed.
Not from flame.
But from annihilation.
His form dissolved around the wound.
He was torn back into the Warp.
The Second Descent
Another giant fell from the bleeding sky.
A Bloodthirster of annihilation.
A herald of total destruction.
Yuki collapsed.
She had nothing left.
Eusonis charged.
The daemon's scepter struck him aside.
The Guard opened fire.
The axe hurled them back.
The creature advanced.
Reality itself felt nailed into place.
Escape was impossible.
Then a massive blade intercepted the killing blow.
A winged daemon struck from the side.
Be'lakor.
The First Daemon Prince.
Chosen once by all four gods.
Rejected by all.
Schemer without allegiance.
"She is mine," Be'lakor hissed. "A gift worthy of the gods."
The Bloodthirster roared defiance.
They clashed.
Eusonis seized the moment, dragging Yuki to safety.
Be'lakor cast aside Astartes and daemons alike.
He advanced.
Eusonis stood before him.
Sword raised.
Silent.
Unyielding.
Lightning split the sky.
Warp portals ignited.
Magnus the Red strode onto the battlefield.
Psychic storms coiled around him.
Ahriman spoke urgently.
"Father—"
"I will destroy you," Magnus growled.
Lightning descended like divine judgment.
Be'lakor staggered.
For the first time, uncertainty touched him.
Terra
"Magnus has extracted the Vice-Emperor," Malcador reported. "Her injuries are severe."
The Emperor did not move.
The silence around him thickened.
Pressure built like a gathering storm.
At last he stood.
"Malcador," he said quietly,
"go to Caliban."
"The Imperium requires a hunter."
Somewhere in the dark
In a place where light could not reach,
a voice wept.
"I'm sorry…
I'm so sorry…"
