Howdy folks! A "What-If?" idea popped in my head about a story of a Chaos Space Marine in the universe of Familiar of Zero and it was pretty irresistible. Our main hero (or anti-hero I guess) will have quite the adventure on his hands once he arrives on a planet that has never even heard of Chaos or the Dark Gods. He's got quite the attitude too, so be ready! Please leave feedback if you have any, as this is my first story!

Disclaimer: I do not own Familiar of Zero, Warhammer 40,000, or anything related or pertaining to those universes.

Chapter 1: Meet the Heretic

"Your failure is the ultimate insult to the changer of ways…" a dark, booming voice echoed throughout the large hall. It was more of a dark cavern, illuminated by light that was etched in colors only from the warp, but the grand scale and architecture of it made it indistinguishable to a great room. The slaves captured in the last raid were still digging in the shadowed corners of it, muttering prayers to the changer of ways and to Chaos as a whole as they pushed their fragile and torn bodies beyond the point of exhaustion to please their new master. However, they were in far better standing then the man at the center of the room.

"My lord! There was nothing we could do! The Space Marines were upon us before we were ready! If-"

"DON'T GIVE ME EXCUSES," the voice instantly silenced the chaos marine in the center of the room. "Excuses are for cowards….and weaklings! Those undeserving of the vision of Tzeentch! Victory needs no explanation…"

"…and defeat allows for none, yeah...," completed the failed marine in a sarcastic voice. It was a well-known quote from the Imperium, and even under the banner of Chaos it still stood true. It felt as if the eyes of Tzeentch himself were boring down into him, crushing him under a force that would likely kill a normal man. But he still had his willpower, augmentations, strength, and training as a Space Marine, allowing him to survive under the gaze of one as magnificent as the lord of change. He was kneeling before a Chaos Sorcerer of the Thousand Sons, his bowed head sparring him the piercing stare of hatred that his master held for him.

I left my chapter for this? Frak me…it's the same damn thing on both sides of the fence!

Glacius was a tactical marine back in the Crimson Fists chapter before he 'messed up' and ended up on the wrong side of the Inquisition. He always had a slight potential as a psyker, barely noticeable to the Imperium, however, the changer of ways sees everything. It took awhile, but Chaos eventually managed to convert him. He was a strange one however, different from other normal and chaos space marines, and it was only a matter of time before his attitude got him in trouble…again.

"Naw but seriously, they-"

"SHUT. UP." the sorcerer screamed at the top of his lungs. The heretics slaving away in the corners could feel the hatred from the sorcerer's words as it hit their eardrums, causing the weakest of them to simply collapse in final death. Those that didn't die were knocked over by the sheer malice carried in his breath.

"I was wrong to take you in. Now I know why the Imperium HATED you so much, why your own brothers held a hatred for you that almost rivals MINE."

"It's the hair isn't it?"

"It's because you don't get results. You are a failure, and now you will see what I do to those who fail me…"

Glacius looked up at the Chaos Sorcerer, who began chanting something in demonic tongue. The sorcerer was quiet at first, but the hateful words were getting louder and louder, and soon they began booming across the entire cavern. The heretics shuddered in fear at the will and power of the sorcerer, whose words were now causing parts of the cavern to collapse. A powerful spell indeed.

If I hit him now…then maybe…yeah!

Glacius figured "Why not?" and decided to take a swing at his horrible boss before he vaporized him. Heck, maybe he could bring him down completely and take over this wretched operation. Tzeentch would love that. Change of command is still change after all! Glacius jumped up and dashed forward at top speed, the sorcerer being only a few meters away. The distance began to close rapidly as his chainsword began whirring about, ripping through the air with the desire for fresh blood.

Did I say the spell was powerful? No, it was outright insane. As Glacius continued his charge, the ground around him cracked and buckled, shattering across the entire hall. Heretic slaves fell into the dark chasms, their screams silent in the cacophony of the planet's cries. Stalactites fell from the ceiling and crashed around the Chaos Marine, who was bent on the destruction of his master. Nothing would stop him!

"ARRRRRRRGGGGGGGGGGHHHHHHHHHH HHH!" Glacius screamed his battle cry as he leapt over a giant chasm, his superior strength carrying him over the colossal gap. His chainsword was screaming in excitement, the taste of flesh so near.

This is it! Prepare to go back to the warp you fat sack of-

A massive bolt of blue lightening arced out of the sorcerer's hands, holding Glacius up in place. The pain was outright horrifying as the lightning dug deep into the chaos marine's body.

"YOU WILL BE BANISHED…..TO A WORLD WHERE YOU HAVE NO POWER….A WORLD, WHERE YOU ARE RULED OVER BY WEAKINGS. YOU WILL BE THE SLAVE…"

"S-Sounds like y-your just sending me back to the Imperium….with their stupid corpse e-emperor and-"

"OF THE WEAK. AND TZEENTCH WILL SEE ALL."

"Yup. Sounds like Terr- EEEEEEEEEEEEEEEEEEEEEEEE!" Glacius exclaimed as he was thrown back faster than a bolter round. As he slammed into the wall, his mind was so focused on what the hell the sorcerer just said that he didn't notice his body being enveloped by a faint green light. Slowly but surely, he faded from existence in the 41st millennium.

Louise Françoise le Blanc de La Vallière was super anxious for her turn in the summoning ceremony. She talked pretty big about how epic and pretty and powerful and whatever her familiar would be, and she was praying that it would stand up to her boasting. Her main rival, Kirche, summoned a fire-breathing salamander, and she just wanted to one up that at least. Hell, she wanted to prove everyone wrong, how they all mocked her and called her "Louise the Zero" since she had zero successful spells since her time at the Magic Academy.

"Alright then, has everyone had their turn?" Professor Colbert asked all of the students gathered outside.

"No, not quite, Miss Valliere hasn't done it," Kirche exclaimed, a sinister yet playful look on her face as she eyed her opponent. Louise simply stepped forward, staring back at her while preparing to summon her minion. And then came the usual mockery that followed Louise anytime a spell was involved.

"It's just gonna be another explosion, nothing special!"

"I wonder what the zero will summon, hehe!"

"We're all gonna die!"

Kirche continued to taunt Louise, "With all that boasting, your familiar will be even better than this salamander right?" she said as she continued to pet her familiar on the head.

Louise simply stuck with her guns, "Of course!" and then proceeded with the ritual. Unknown to everyone else, she was really worried that her familiar would end up as a weak, fragile creature or worse….a peasant…

"My servant that exists somewhere in this vast universe!" she began. Everyone else was a bit surprised, as that was an interesting way to start a spell. But they let her continue, "My divine, beautiful, wise, and powerful servant, heed my call! I wish and usurp from the very bottom of my heart, answer my guidance and APPEAR!"

As she flicked her wand in front of her, everyone held their breath as a green portal appeared before her. Everything seemed normal at first, but then the spell took a turn for the worse. Blue lightening erupted from the sides of the portal, arching across and burning the grass rapidly. The sound was deafening, as though a thousand mouths cried out in pain (I love that DoW quote!) while the wind howled out of the portal. The wind began knocking students and their familiars off their feet while assaulting their ears violently.

"What the hell are you doing Louise!?" Kirche shouted. Hell, even Louise didn't know. This was the most terrifying summoning experience anyone had yet seen. The noise and wind became even louder, stronger, and the lightning was now arcing off of the nearby walls of the academy, splintering stone and showering it upon the frightened students. It seemed as if hell itself was coming out of the portal. Suddenly, everything was bathed in white as the portal exploded and overwhelmed everyone.

The dust and smoke finally settled. Louise was lying on her back, small parts of her cape burning from the brutal spell that left a crater in front of her. She looked up to see Professor Colbert trying to help her up.

"Are you okay?"

"Ugh…yeah…w-wha, what happened?" Louise asked while rubbing her forehead.

"You summoned your familiar, which is…" Colbert's voice trailed off as he glanced into the crater. Louise noticed his expression, which was one of confusion, anxiety, and fear. "Louise…what on earth did you summon?"

Louise stood up, dusting all the dirt off of her as she looked into the crater. And there it was. The figure was huge, easily twice as tall as her and about as wide as she was tall. His entire body was covered in a dense armor that was a dark blue with spikes and chains puncturing out of the shoulders. He looked like he had come from the depths of some eternal war, as his armor was pocketed with craters from bolter rounds, scratches from the claws of demons and xenos, burned from lightning and lasguns, and covered in other marks that only a soldier would be able to identify. His helmet completely covered his head while his eyes glowed a dull, faint red. The most peculiar thing about him was the symbol on his chest: an eight-pointed star with what looked like an eye in the center.

Louise gulped as she stared at the armored being. It was the complete opposite of 'divine and beautiful', but it did look powerful. Very powerful indeed. Hey, that was one plus! Lousie turned to Kirche, who looked completely unfazed as she continued to pet her salamander.

"Mine looks way more powerful than yours!" she exclaimed triumphantly.

"It hasn't even moved Louise…it's just…laying there…." Kirche stated nonchalantly.

"Erp!" Louise squealed. She was right, the armor was just laying there, like it was asleep or something. How dare her new familiar be asleep already!

"Mr. Colbert! How do I make it-"

"Finish the ritual Louise," he stated as he adjusted his glasses.

Glacius was completely immobile. The spell must have short circuited his armor, and right now it was locked in place. No amount of strength would move it in his current mode. The trip was almost instantaneous for him, as he could tell the scenery had changed. Instead of the malice-filled caverns, he could sense that the air was more…peaceful. The ruin of war had not yet reached this place. Tzeentch would change that, oh yes he would!

Glacius soon began plotting all of the mischievous things he could do to this untouched paradise, from conquering and enslaving all living things to bullying kids in schools. Oh what a magnificent fate the changer of ways had brought him! It was time to-

Oh yeah. He couldn't move.

Suddenly, as if to answer his statement, his armor began powering back up. Sensors began displaying data on his HUD as his vision came back to him. The sun was awfully bright, as clear days such as this were rare in the hive cities. He gave a mental command to dim the brightness to something more normal, but then he looked up and saw something. A little girl was standing over him, staring down at him with a determined look on her face, like she was trying to prove something. She was wearing a fancy looking cloak and had really strange, pink hair.

"Step aside before I-" before Glacius could finish his sentence she knelt down and kissed the ventilator over his mouth. He was about to explode in rage but then he started feeling really warm. Like kinda painful. Ok it hurts now.

"ARRRRGGGGGGHHHH!" He felt like he was being burned alive by the inquisition, but most of the pain was focused on his left hand. It subsided quickly though, and he then stood up, bringing his full height to bear onto the tiny girl.

"What the hell was that!?" Glacius shouted, his voice amplified by the external speakers on his armor. He was one of the newest chaos marines, not completely corrupted with evil and hatred yet, but from his voice alone the students couldn't tell the difference. He sounded like the devil himself. His titanic figure towered over the entire crowd, engulfing all of them within his shadow of darkness. The only one who didn't look frightened was the girl in pink hair standing before him, her hands on her hips.

"I'm Louise Françoise le Blanc de La Vallière, and you are my familiar," she simply stated.

"Your what!?" the chaos marine exclaimed. He had never heard of that before.

"My familiar! You have to do everything I say!" she shouted back at him.

Glacius was silent for a bit as he silently thought to himself.

YOU WILL BE THE SLAVE…

The voice of his master echoed through his head. But wait a minute! He wasn't here! Haha!

"BWAHAHA! HAHAHAHAHAHAHAHA! HAHAHA!" Glacius broke into a deep laugher, his voice carried by the vox speakers. Who did this girl think she was? As Glacius continued laughing he simply began walking towards the stone wall so he could leave this place.

"I'll be going now!" he shouted triumphantly once his laughter died down. He was about to reach the wall when his body started tensing up for some reason. It became tighter and tighter, and it was almost hard to move. Suddenly, a voice entered his head, daemonic in origin.

You will serve, treacherous one. The Lord of Change dictates it.

Wha!? What the hell? You gotta be kidding me! So clooooooooooooooooooooose!

The chaos marine felt his body starting to move on its own, turning back around towards the gaggle of students. It was as if the daemon itself was controlling his body. Glacius decided it was best just to serve the little girl then let him be controlled by a daemon. He had seen a few of those possessed marines...they weren't too pretty. He began walking on his own back towards her, the will of the daemon backing off as his puppet performed the desired action.

Gonna have to do something about that daemon...

Glacius could feel his pride slowly eroding away as he walked back up to the little girl. Man, this was embarrassing! To act like a hotshot only to have a daemon put you down and humiliate you in front of everyone. Oh well, that didn't matter. Once the daemon was gone, Glacius could do whatever.

He.

Wanted.

He kneeled before the little girl, his crouched frame still slightly taller than her.

"Master...your wish is my command," he stated in a sinister voice, smiling behind the dark helmet.

To be continued...

So what do you guys think? Yay or nay? Any feedback will be appreciated!
