Chapter 46 Weak Flesh and Blood
Acinos: Break the crucible. Break your chains.
The Tomb: You were forged for this purpose. You belong to the machine.
Acinos: To hell with destiny. My fate is my own.
Pharus: I will help you—
—Just kidding.
The World of Medusa
The Tenth Primarch's capsule fell upon the death world of Medusa, deep within the mist-shrouded northern reaches of the Imperium.
Medusa was a world of extremes:
lethal cold and volcanic fire
shifting tectonic plates and migrating landmasses
vast technological graveyards buried beneath the crust
iron-rich storms that could strip flesh from bone
Its people lived in wandering techno-clans, fighting over scarce resources and scavenging relics from ancient ruins older than memory.
Some Imperial scholars later theorized Medusa had once been a battlefield of ancient machine empires — perhaps relics of the Dark Age of Technology, or something older still.
The Silver Wyrm
The Primarch's capsule punched through a mountain and embedded deep beneath the surface.
When the child emerged, he found himself inside a buried machine complex — silent, sealed, and utterly dark.
Then something stirred.
A colossal metallic serpent unfurled from the shadows — a vast mechanical wyrm whose segmented body shimmered like living quicksilver.
The clans would later name it Asirnoth, the Silver Wyrm.
The Primarch fought the creature. Sparks and molten metal filled the chamber as flesh met living steel.
Neither could destroy the other.
Sensing stalemate, the wyrm burrowed through rock and vanished into the depths.
The child emerged into the storm-wracked world above and swore an oath:
He would hunt the Silver Wyrm.
Ferrus Manus
He did not join the clans.
Instead, he observed.
Learned.
Adapted.
He was given a name:
Ferrus Manus — the Iron Hand.
At first the clans distrusted him. Some believed he had unleashed the wyrm. Others thought he was its master.
But they watched him descend into forbidden ruins.
They saw him destroy ancient war-machines no clan dared approach.
They saw him return with knowledge.
With tools.
With fire.
With steel.
They realized he was not their enemy.
The Death of Asirnoth
Ferrus found the wyrm again within a volcanic rift.
Their battle shook the mountain roots.
He dragged the creature into molten lava and buried it beneath liquid fire.
But the wyrm's necrodermic hide — living metal beyond comprehension — fused with his forearms as the magma consumed them.
When the lava cooled, Ferrus rose with hands of living metal.
Unbreakable.
Unyielding.
Iron made flesh.
Medusa's Forge
Ferrus did not unify Medusa.
He improved it.
He encouraged rivalry between clans, believing competition forged strength.
He shared knowledge, but never removed hardship.
Strength must be earned.
Weakness must be burned away.
Under his guidance, Medusa's clans grew harder, sharper, stronger.
The Emperor Arrives
The Emperor and Yuki arrived upon Medusa.
Ferrus was waiting.
"I am your father," the Emperor said. "Join the Imperium."
Ferrus nodded once.
"Fulfill one condition."
"What condition?"
"Fight me."
The Emperor closed his eyes briefly.
"…What kind of fight?"
Ferrus grinned.
"The only kind that matters."
Yuki bit her lip to keep from laughing.
The Emperor flicked her forehead with a psychic tap.
"…Very well."
The Battle of Iron and Will
Their duel lasted days.
Mountains collapsed.
Stone liquefied.
Storms scattered.
Ferrus fought with relentless ferocity.
The Emperor fought with restrained precision.
In the end, Ferrus fell — defeated but exhilarated.
Lying upon shattered stone, he laughed.
"Good. I have much to learn."
He swore allegiance.
The Emperor was satisfied.
So far, Yuki's worries seemed unnecessary.
"So, Sister — Our Turn."
On the return voyage, Ferrus spent days analyzing the duel, identifying flaws in his technique and conceptual weaknesses in his tactical flow.
He requested a rematch.
The Emperor refused.
"I do not have days to spare. Defeat your sister first."
Yuki nearly exploded when she heard.
Am I not busy too?!
Her responsibilities included:
stabilizing Astartes gene-seed flaws
drafting Imperial administrative systems
balancing political structures
monitoring Legion cohesion
The Emperor chose the direction.
Malcador kept the engine running.
Yuki tuned the machine.
But…
It had been a long time since she fought seriously.
"…Fine," she said. "Let's fight."
The Duel
They chose a barren world as their arena.
"No weapons?" Ferrus asked.
"You didn't bring any either," Yuki replied.
On the Imperial Wings
Zero Legion Astartes placed bets.
"One ration tin says five hours."
"Ten hours. He looks terrifying."
They never doubted their mother's strength.
She had fought in the Unification Wars.
She had survived horrors few could imagine.
Iron Against Flesh
Ferrus discovered something unexpected.
Yuki did not fly.
Did not summon psychic flame.
Did not draw a blade.
She fought him with her bare hands.
Ferrus possessed greater raw strength.
But Yuki possessed superior combat judgment, timing, and adaptive response.
Hour after hour, Ferrus found himself pushed beyond equilibrium.
Fifteen hours later, he lay on the ground.
Yuki sat beside him.
"Well? Satisfied?"
He laughed softly.
"Yes, sister."
He understood now.
The Emperor had been holding back.
Greatly.
But Ferrus did not resent this.
Defeat meant growth.
Growth meant strength.
Brothers
"What are my brothers like?" he asked.
Yuki considered.
Gangsters, Vikings, and repressed philosophers, she thought.
"They are… good men," she said instead. "You'll see."
"Are they strong?"
She sighed.
"Yes."
Terra Waits
On Terra, Malcador surveyed the gathering Primarchs.
Horus glared at him periodically.
Russ devoured cheap street food with enthusiasm.
Mordecai Threxion sipped tea with composed elegance.
The air felt dangerously quiet.
A functionary burst into the chamber.
"My lords — the Princess and the new prince are fighting!"
"What?" Malcador snapped. "Explain yourself!"
The man produced a report with shaking hands.
"Combat confirmed."
Impossible.
Ferrus Manus was many things — relentless, obsessive, iron-willed.
But to provoke Yuki?
Equally impossible.
Another official rushed in.
"Prince Ferrus's flagship has entered Terra orbit."
Malcador closed his eyes.
He looked at:
Horus frowning
Mordecai watching silently
Russ baring his teeth in excitement
This would be… interesting.
Very interesting.
