Here ya go. A Warhammer 40K !PrimarchPercy thing. Probably crap, but it had to be done.

Thunder and Glory

Chp 1.

Cast down.

The sun beat down on Camp Half-Blood, seemingly intent on burning all it saw to ash. The ring of steel on steel was deafening the entire camp, as Percy fought Clarisse, Annabeth and Jason. His vision seemed to follow each of his quarry's individually, tracking their every movement. Riptide was an extension of himself, moving faster than thought. Jason's gladius sped towards his chest and was intercepted, no longer a threat for a few precious seconds. This had been raging on for an hour, but was about to come to an abrupt end.

The unmistakable, earthshaking sound of Zeus's masterbolt flashed across the sky, summoning the council. All paused their tasks too look up and admires it's majesty, before disregarding it as not important to them.

Up on Olympus, the only sound was shocked silence at what the Lord Of The Skies just said. Eventually, Poseidon broke the silence.

"YOU WOULD DARE ACCUSE MY LOYAL SON OF HERESY!"

"Silence, Uncle." Athena commanded. "The evidence is severely mounted against him. He has had some form of contact with someone in the future, and that is enough to doom him. The mind cannot take knowing it's future, and he must die."

"B-But.." Poseidon was grabbing at straws. There was nothing he could do, and he knew it. His dropped and he sighed, a single tear rolling from his cheek and hitting the marble floor with a splash. "So be it."

Zeus allowed himself a small smirk. "BRING HIM IN." He commanded no-one in particular, but the doors opened all the same, and there, bruised and in shackles, stood the Hero of Olympus, damned by a confused conversation with someone claiming to be the Emperor of Mankind.

"W-What's going on?" Percy begged of them, but received no response.

"PERSEUS JACKSON" Zeus boomed, staring down at the boy in triumph "YOU STAND ACCUSED OF HERESY AND BETRAYING OLYMPUS. WHAT SAY YOU IN YOUR DEFENCE?"

The boy gawped.

Athena smirked.

Poseidon sobbed.

Zeus glared.

The rest of the council was silent.

And then Percy exploded into light.

He was stood in what appear to be a room, but everything was blindingly white and seemed to be infinite in all directions. He was looking around hoping for a person, a landmark, a anything when he received an unpleasant surprise.

There was a horrific shrieking noise, the sound of rending metal, forcing him to his knees and making clap his hands over his ears. A black blob of what was best described as nothingness appeared in front of him, too bright to look at and too entrancing to look away. Suddenly, it stopped.

When he looked up, a figure that appeared almost human greeted him. It was a woman, unnaturally tall and eyes the colour of the cosmos, in a black dress studded with stars. She studied him for a moment, then gave a condescending laugh.

"W-Who are you?" Percy stammered out.

She laughed again. "I, my dear boy, am Chaos, creator of all. And you" She curled a finger under his chin, pulling it up, forcing him to stare into her eyes "are of great interest to me."

He bolted upright, panicky. "What do you want of me?!" Then his gaze darkened. "It was you, wasn't it!" His voice filled with rage. "You set me up, you made me talk to whoever he was, and you had me accused of heresy!" he barked, a single tear rolling down his cheek.

She did not even flinch, staring at him coolly. "No, my dear, that was all them." Chaos spoke. "I... am sorry for you. About them all."

"What about Annabeth?" he demanded, his eyes taking on a sudden hardness.

She smirked a bopped his nose like a child, much to his chagrin. "And that steel right there m'dear is what will make you such an excellent Primarch."

"A what?" He questioned, all thoughts of Annabeth temporarily forgotten.

"You are aware of your situation, Perseus. You may die horribly and be tortured for all eternity in Tartarus, or you may be born again as a godlike warrior, a son of the God-Emperor of Mankind."

He pinched his nose and sighed. "But Annabeth-"

"Was the one who accused you. I swear it on the River Styx." Thunder boomed in the distance as testimony.

Percy died a little inside right then.

But his grief was replaced with deep black rage, and he steeled himself and spoke the fateful words.

"Make it happen."

Tallivan was a semi-peaceful world. It was %95 water, the few chunks of land held its human citizens, mainly farms and smallish towns, as yet uncovered by the Imperium. The population of the a small unnamed town was going about the daily business, largely farming and building, when something very much out of the norm occurred.

It was all so sudden. There was a great streak of fire, and the sound of the oxygen particles being rendered apart by the sheer force of the drop pod. It screamed down towards the surface, and slammed into the middle of a farm at supersonic speeds, causing all earth nearby to surge upwards in something akin to a volcanic eruption.

When the dirt and smoke finally cleared, an unharmed teardrop shaped drop pod stood in the ground, a deep oceanic blue. The townsfolk gathered around, waiting for any kind of action.

"It's the xenos, I tell you! We must destroy it!" The town leader cried.

The people murmured assent.

Before they could talk further, a great creaking was heard, and the four doors of the drop pod blew open, revealing its precious cargo.

A small boy, no older than four, sat sound asleep in the drop pound, undisturbed by the atmospheric re-entry.

The next few months were hard. The towns people took in the boy, feeding him and nurturing him. Feeding him became quite hard when he started eating that of three men, and growing like them too. His name, apparently, was Perseus. He was working in the fields, and could pull a plow by himself. He rapidly grew tall, and had a smile so white you risked blinding yourself if you made him happy. By the fourth year of living there, he was his full Primarch height of nine feet tall, so large he built his own house to avoid cracking his head (Before he got his own house, he did this anytime he entered a room). He had every girl of the village swooning over him and his looks. He was a god among them. Little did he know, the Emperor would soon come and prove this.

Thalia glared at Annabeth scowling.

"How could you do that to him?!"

Were the first furious words that leap from her throat. In front of the councillors. In the middle of a meeting.

"Do what? To him? He was a traitor!"

Thalia barely held herself back from punching Annabeth in the face.

"Oh really? We both know Seaweed Brain! He wouldn't betray anyone! His fatal flaw is loyalty for fucks sake!"

Annabeth recoiled.

"Thalia! Calm yourself!"

She slapped her.

Annabeth backed away in shock, her hand subconsciously going to the mark on her cheek.

"Well, you didn't take long to move onto the next fine piece of ass, did you now Annabeth?" Thalia hissed, jabbing a finger at Drake, Hermes leader and Annabeth's new boyfriend. Thalia stormed out.

She swept her gaze around the camp. It all seemed so surreal. People were laughing and smiling, the sun was shining and everyone seemed happy.

Thalia hated it.

Percy just died, her best friend, her crush that drove her to join the hunters, hero of the world thrice over, and people didn't seem to care!

She sprinted to the Zeus cabin, angrily rubbing at the tears beginning to flow down her cheeks. She kicked open the door and collapsed onto the nearest bed, taking a brief second to note that Zeus had rearranged everything and that it seemed less like home than ever, before dropping her head and beginning her sobbing proper.

Then for the briefest moment, she saw him.

He was sitting on the end of her bed, saying nothing. Just sitting there, in all his glory. Then he smiled.

Then he was gone.

She blinked once, twice, thrice, then wailed.

"No! Don't go!"

Rachel knocked on the door.

"Go away!"

"Thalia..."

She came in and sat down next to Thalia, her own tears beginning to fall. She pulled her in for a hug, which she surprisingly accepted.

Then she bolted upright, and green smoke came from her mouth.

"Seven shall go the world of forever blue,

face the evil of the dark war,

and through fire and sword shall be born anew."

"Rachel!" Thalia shrieked and grabbed her before her unconscious friend hit the floor, and lowered her onto the bed.

She steeled herself.

She knew she had to tell Chiron.

The Emperor sat on his throne on in the bridge of the Adeptus Imperator, his flagship. They were currently in orbit of a world that was about to be brought into submission, by the name of Tallivan.

He sighed, ready for another battle.

"Prepare the orbital bombs!"

"Sir! My lord! That might not be the best idea..." The ensign squeaked, realising he had just challenged the Emperor's wisdom.

"Hmmm? And tell me, why is that so, Ensign Ackbar?" leaning down to glare at the officer.

"W-well sir...it appears..."

"SPEAK UP!" The senior officers cringed, preparing themselves for the psychic immolation that was sure to come.

"S-Sir... It seems there may be one of your sons on the planet..."

That shut him up.

The other Primarchs on the bridge (Horus, Sanguinus and Fulgrim) began to murmur to each other, half-excited and half-nervous about meeting a new brother.

"Well then... Deploy the Astartes Legions!"

"Yes, Father!" The Primarchs said in unison, and stomped off to prepare for battle.

The Emperor, now alone on the bridge, brought up a picture of Percy in New York.

"My last son... You will be with us soon."

The gasps of horror could be heard all over town. The sky was thick with falling drop pods, streaking down, painting the sky red with jet exhaust.

The alarm bell began to toll, and the villagers fled inside, all except Perseus.

He stood outside, staring at the sky. He'd had a strange feeling lately, knowing something was going to happen.

He was right.

A drop pod screamed into a nearby house, causing Percy to spin around and stare at the annihilated structure and the bloody remains of the occupant that had been unlucky enough to be caught under it.

Percy saw red.

He ran at the pod with a savage roar, smashing against its doors with anything he could get his hands on, currently a large tree. The Astartes inside panicked a little. The doors propelled open, blowing Percy backwards. The Astartes poured out rapidly targeting him and screaming at him to stay down. He obliged, not wanting to be on the receiving end of what some faint part of him recognised as a bolter.

A shadow fell over him. He glanced upwards and scanned the person in front of him.

He was frankly beautiful. He had flowing silver hair, an elegant face, and kind eyes. But the most interesting thing was he stood the same height as Percy. The man grabbed his hand and hauled him up, eyeing over his brother.

He smiled "Hello, brother. My name if Fulgrim."

Percy clasped his arm at the elbow, instinctively knowing this man was in fact his brother.

"A pleasure to meet you. I'm Perseus. NOW WHAT THE HELL ARE YOU DOING TO MY TOWN?!"

Fulgrim looked surprised, but understanding came over his elegant face.

"You are aware of the Imperium, yes?"

"W-Well..yeah, but I don't know how..."

"You are a Primarch, like me and our other eighteen brothers."

"Eighteen?!"

"Mmm. We are not children of the womb though. We were created by our Father, the Emperor of Mankind."

"I- I remember him I think... Tall...Gold..." He smirked. "Huge ego.."

Fulgrim laughed raucously. "Oh, we'll get along just fine.."

Aboard the Astartes Imperator much explaining was going on. Percy was informed he was the Father of a legion of genetically engineered super soliders, himself one of the man before him.

"So.. This legion. Is it already there?"

"Some of it." The Emperor replied. "When we find your brothers, we always have a skeleton legion ready, in case of combat. Fulgrim has the Emperor's Children, Sanguinus here the Blood Angels-" Sanguinus gave him a saucy wink "Leave it till your brother matures. Don't think I don't know about you and Horus. Also, Horus has the Luna Wolves." The Emperor said, gesturing at the totally-not-blushing Primarch.

"And me?" Percy asked tentatively.

He clasped his son's shoulder.

"You, my son, are the Primarchs of The Sons Of Perseus."

The hangar bay opened, and there the beginnings of his legion stood. They were clad in ocean blue power armour, with lighter blue trim. They stood straight in lines, the very definition of an immovable force.

Percy smiled.

"My sons" he began, finding the speechmaking coming very naturally to him. "You do not know me, and I do not know you. Hopefully, in time, we can rectify that. But for now..."He jabbed his fist into the air. "Let us claim our homeworld!"

"FOR THE OCEANS BLOOD!" The shout rose from the hundred throats, and was utterly deafening.

"Now, dear brother.." Sanguinus purred. "Let's get you into your armour.."

The Emperor smirked at Percy's mildly terrified expression.

"Ignore him. He always talks like that."

In half an hour's time, after much suffering of Fulgrim's and Sanguinus's wandering fingers, he stood before his legion, nine feet tall, clad in blue armour with a trident carved into his chest, looking absolutely majestic.

It was time for the Son's Of Perseus to be blooded.

There we go! Hoped you liked! R&R saying which you want to be update more, this or Blood And Fire. If anyone is wondering why Sanguinus and Fulgrim are acting kind of whorish is because that's how they were in the old HH stuff. Goose out.
