Mundus Planus.
An Administratum designation few could pronounce and none cared to use.
Its people called it Chogoris.
Unlike most Primarch homeworlds, Chogoris had not been smothered by hive-cities or strip-mined into dust. Vast grasslands rolled beneath endless skies. Rivers ran clear. Herds thundered across open horizons beneath cold blue air.
Its people lived at the edge of gunpowder warfare — muskets, rockets, curved sabres and horse archery — but its true strength was mobility, not machinery.
To the east stood the Palatine Empire, a decadent sedentary state ruling walled cities and fertile valleys. To the west stretched the endless steppe, home to nomadic tribes who raided, traded, warred, and vanished like storms.
The empire raided the steppe for slaves.
The steppe remembered.
It was upon those grasslands that a child fell from the sky.
A tribal chief named Ong Khan found him and raised him as his own son, believing him a gift from the eternal sky.
He was named Jaghatai.
The Birth of the Khan
When the boy was still young, Ong Khan was murdered by rival tribes.
The child did not weep.
He gathered riders.
They rode before dawn.
When the sun rose, the enemy tribe no longer existed.
From that day forward, Jaghatai swore an oath:
The steppe would be united.
Endless blood feuds would end.
War would have purpose.
His rise was swift.
Tribes were offered a choice:
Submit.
Or be erased.
Most submitted.
Those who did not vanished into memory.
The Empire Makes an Enemy
When Jaghatai was ten, he was separated from his riders during a storm and encountered a Palatine slave-hunting patrol.
Only one horse returned.
A mutilated corpse was tied to its saddle.
Pinned to the corpse:
The steppe are not your prey.
War followed.
The Palatine phalanxes marched with banners and drums.
They died in dust and arrow-storms.
Heavy infantry broke beneath feigned retreats, encirclement strikes, and mounted archery.
The emperor of the Palatine Empire fled.
He did not flee far.
When Jaghatai's riders surrounded his capital, the Khan offered a choice:
Deliver your emperor.
Or die with him.
By dawn, the gates opened.
By noon, the emperor's head was presented.
By dusk, Chogoris was united.
The Khan Refuses the Throne
Victory did not bring peace.
The Khan hesitated.
He had seen rulers become parasites.
He had seen power rot men.
He feared becoming the very tyrant he despised.
On the steppe, he spoke openly with his generals:
"If I sit upon a throne, will I become the man we overthrew?"
None could answer.
Then the sky split with light.
The Arrival of the Emperor
Golden light descended from orbit.
Thunder without clouds.
Machines beyond imagination.
When the Emperor stepped onto Chogoris, Jaghatai knew.
This was not merely a king.
This was destiny made flesh.
Before his astonished warriors, the Khan knelt on one knee.
Not in surrender.
In recognition.
Aboard the Imperial Vessel
On the voyage to Terra, Qin Xa drank in silence.
"We do not question you, Great Khan," he said at last. "But why kneel to this foreign lord when you knelt to none before?"
The Khan turned his cup slowly.
"When I saw him," he said, "I saw a future of unity… and mountains of bones required to build it."
He did not know what refusal would bring.
But he knew arrogance against an invincible force was not courage.
It was stupidity.
Yesugei, Stormseer of the steppe, understood. He had felt the Emperor's presence like a storm pressing upon reality itself.
If Chogoris had resisted, the Emperor alone could have ended them.
Yesugei lifted a hand.
Qin Xa fell silent.
Hasik asked quietly:
"Where do they take us?"
"Terra," the Khan replied.
"And the golden warlord?"
"He remains. His daughter escorts us."
Yesugei remembered her wings of light and the pressure in the air when she moved.
She was not human.
Not entirely.
"What kind of person is she?" he asked.
The Khan frowned — a rare sight.
"I do not know."
A knock sounded.
The door opened.
Yuki stood framed in lamplight.
"Prepare to disembark. Terra awaits."
Terra
"#*@! This empire is a corpse pretending to breathe!"
Horus and Magnus restrained the furious Khan.
They could not understand the sudden eruption.
But the Khan saw clearly.
He had spent his life resisting corrupt rulers and lifeless systems.
Terra was order without vitality.
Function without spirit.
People moved like components.
No sky.
No horizon.
No freedom.
Malcador watched calmly.
At least this Primarch was honest.
Unlike certain… theologians.
"Brother, do you believe—"
Guilliman clamped a hand over Lorgar's mouth.
"Not now."
The Khan Observes
He did not rebel.
He watched.
He criticized.
Everything.
Architecture.
Crowd movement.
Logistics inefficiencies.
Psychological stagnation.
Bureaucratic rigidity.
His language was sharp and inventive.
Magnus found himself impressed.
By evening, the Khan had insulted half of Terra's structural philosophy and three-quarters of its administrative psychology.
Then he returned to his encampment.
And his anger vanished.
Strategy
Understanding precedes action.
The Khan now understood:
The Imperium was rigid.
Flawed.
Decaying in places.
But beyond it lay worse horrors.
If this structure fell, humanity would not survive.
His solution was simple:
Let others suffocate in bureaucracy.
He would remain free.
The Visitor
Inside his tent sat Yuki, holding a cup.
"You're back," she said. "What is this drink?"
"Fermented mare's milk," the Khan said, laughing. "Chogorian airag. I can send you a shipload."
She shook her head.
"It won't get me drunk."
He laughed again and sat.
"So, sister — what did you wish to discuss?"
She told him.
Of Chaos.
Of the Warp.
Of the predators beyond reality.
Of what truly threatened mankind.
The Khan's expression hardened.
His instincts had warned him of the immaterial.
But the truth was worse.
Much worse.
After long silence, he spoke:
"I judged too quickly."
The Imperium was a cesspool.
But outside it lay an ocean of rot.
And this cesspool was humanity's best defense.
The Gift of Freedom
"You are the one I trust most," Yuki said quietly. "You understand balance."
He listened.
"I know you dislike the Imperium," she continued. "So I give you this."
He looked up.
"What?"
"You will be subject to orders, not summons. Outside of major wars, you choose your deployments. As long as you fight for humanity and do not betray the Imperium, no one will command your movements."
Silence stretched.
The Khan finally spoke:
"Why?"
The Question of Ambition
"Why do you stand here? Why sacrifice so much?"
The Khan believed all action came from ambition.
Rulers sought dominion.
The greedy sought wealth.
Even he had unified Chogoris from ambition.
The Emperor possessed the greatest ambition he had ever seen.
But Yuki?
Her ambition was… small.
So small he could not define it.
Yet she carried the weight of an empire.
Why?
Yuki rested her chin on her hand and smiled.
"Khan… because I wish to live with dignity."
The silence broke.
The Khan laughed — deep, wild, genuine.
He raised his cup.
"Sister Yuki. I, Jaghatai Khan, swear this: my warriors, my horses, and I will answer your call whenever you require."
Yuki only smiled.
