Oh boy, a warhammer fanfic in the world of PJO! Awesome!
Please, please do not screw this up, I beg of you!

This is so far pretty good, don't get me wrong, I might sound a bit critical of this story, but I do not by any means hate it. However, the beginning was...meh. It should not have been a chaos fanfic first of all. Why can't the emperor, a godlike being more powerful than the chaos gods sense his own son on the planet and how come an admech dude can? the primarchs are more than nine feet tall. Sons of Perseus sounds too much like Sons of Horus, but the legion cry I think is nicely done.

based on what both have done, aren't the primarchs more powerful than the greek gods however?

The Emprah would have crazy shit going on in his head, as they did just drop out of the warp, and had the gellar fields still up. They had to rely on the ship's sensors for detecting Percy. Crap, did I only make him 9 feet tall? Someone remind me to edit that. I realise the name is rather crappy, but I've always been terrible at coming up with convincing names beyond "Waffle Legion" Seriously, that's what I wanted to call my first Space Marine army scheme. Luckily, my friend stopped me. And Sons Of Horus, this is Pre-Heresy. So no traitors. Yet. As for the avatar of Chaos thing, well, you'll just have to wait and see. :D

Without further ado, enjoy!

The citizens of Tallivan were afraid. Afraid of the stars. Afraid of their protector, Perseus that had been abducted. Afraid of the alien craft in orbit, claiming to be from somewhere called Terra. But most of all, they were afraid of their fate.

When the first craft had landed, a man had walked out in strange robes, bearing a staff, glowing with sheer power. They had killed him. A garbled transmission from above had promised blood.

The four comets screamed through the sky, too regular to be natural and too fast to be falling accidently. The people of the city looked up and saw them, jets breathing trails of fire through the tortured sky. When they made landfall the earth reared back and cratered under there might, the surrounding land aflame.

These were hurled by no angry god.

But they did come bearing angels.

Thalia was one part confused, two parts angry, and one part afraid.

The Hunt was moving at a forced march, and had been for three days. Whatever was going on, it was big. She was concerned for Camp, for Annabeth, for Percy. She'd received no word of the outside world for years. But as Artemis's Lieutenant she'd caught snippets of her conversations. What she heard both elated and terrified her.

Percy wasn't dead.

Camp Half-Blood. A place of quiet and learning, of pleasant childhood memories and general good times.

Right?

Wrong.

Camp was in chaos.

The Big House was closed, and had been for the whole day. The camp councillors were inside, the shouting audible from most anywhere. An edict had been issued down from the gods, causing anger throughout the demigod world.

Any child of Poseidon found was to be killed immediately.

The Astartes caught citizens of Tallivan by surprise. The pods had burst open and started gushing out bolter fire in great streams before people even had time to duck.

The Emperor's Angels poured from the strike craft, a river of blue power armour. Men, women and children ran screaming from the Sons Of Perseus like burglars from an alarm.

The city fell within the hour.

Annabeth smashed her fist on the table.

"THIS IS BULLSHIT!"

She was angry, no, furious. She was an inferno of rage.

"Annabeth, try to calm your-" Chiron attempted, only to be cut off by an incoherent scream of rage.

She was having trouble digesting what she had been told in the past 48 hours. Apparently, humanity was alive and well in the far, far future, and that they were conquering galaxy. That alone did no surprise her. What did suprise her was that they were apparently doing it with roughly one million super soldiers who referred to others as "mortals."

The gods did not exist in this era.

More importantly (Well, not to the gods, but to her.) was that said "Space Marines" had gene-fathers, called Primarchs.

The revelation was that Percy was a Primarch.

The sly fucker.

Tallivan was the Imperium's. Perseus had earned his title, bringing the world into compliance with fire and sword.

He was a cyclone of death and despair, spinning into the enemy flanks with a giant power sword, allegedly called Riptide, and storm bolter.

His First Company Captain had roused the troops before assaulting the final military fortress, an ugly citadel, but well defended.

"Warriors of the Imperium! As always, our enemies outnumber us. Each of you must be an army in your own right. But fear not!

The Emperor is with us, AND WE ARE INVINCIBLE!

OUR DREADNOUGHTS SHALL CRUSH THEM, OUR TANKS WILL FLATTEN THEM, OUR INFANTRY WILL DECIMATE THEM!

ANGELS OF DEATH! SONS OF PERSEUS! GO FORTH AND CRUSH THE ENEMY FOR THE EMPEROR!"

The crash of fists saluting on ceramite chestplates could be heard a mile away.

"FOR PERSEUS AND THE EMPEROR!"

Athena stood in front of her daughter. No one else might tell, but she was worried. Very worried.

"Daughter."

"Mother."

She hesitated. "You are aware of Perseus's... predicament, yes?"

Annabeth scowled. "I am."

Athena swallowed. "We believe we can send someone to his dimension."

Annabeth's eyes widened in shock, her jaw sinking slightly.

Athena continued before her daughter could speak. "Only a small team mind you. Enough of his close friends to bring him to his senses."

Annabeth seized the opportunity.

"Bring him to his senses, or kill him?" she asked bluntly.

Athena just looked on.

"Assemble your team."

War, as Percy soon found out, was bloody loud.

He sprinted across the battlefield, dodging mortar and small arms fire with impunity. The endless crackle of bolter shells and the thundering kaboom of the artillery pieces, the thuds of the dreadnoughts and the screams of the wounded.

And he loved it.

They were in the citadel now, clearing the hallways.

"My lord, we have incoming life signs!" One of his honour guard, Maxus, he thought, shouted.

"Thank you my son." Perseus lazily replied. He lifted the bolter and opened fire as the three defenders came around the corner, shredding them like so many chunks of meat. They stormed the hallways, clearing them, their bolters never falling silent. At last, they approached the throne room. At the mahogany doors, Percy stopped.

"Leave me, my sons. This is for me and me alone."

The captain of his guard hesitated but complied. "Aye, my lord."

Percy pushed open the doors, revealing a huge room dominated at the far end by a throne, cast from iron. He walked down the vast hallway with ease, staring down the old man sitting the throne.

"And so he comes for me." King Galbatorix croaked, barely able to open his eyes to glare.

"And so I come." Percy repeated, his voice soft. He stopped at the base of the throne. "Surrender, old man, and you shall not be harmed."

"Pah! If I had known you were to betray us, I would not ha-" He was lifted into the air, choking.

Percy held him there, his green eyes pools of rage. "I DID NOT BETRAY YOU! I BROUGHT YOU INTO THE IMPERIUM."

He brought the king down to eye level. "You can join me in my new world..." He drew Riptide ominously. "Or you can die in your old one."

The king, to his credit, glared, defiant to the end. "Never."

Percy smiled cruelly. "Your choice, old man." He brutally kicked the man onto his knees, lifted Riptide, and with a deadly schnick, crowned himself King of Tallivan.

Well there ya go guys! Tell me what you think in the reviews!

Goose out!
