Hey guys this is an idea for a story I have had in mind for a very, very, very long time. I was really sick recently and then I got a new game which I got addicted to and work pickewd up whih is why I havent written anything in a while I got it from the story Faust, where a young man makes a deal with the devil known as Mephistopheles and shit happens, so I got to thinking what if Harry was like Mephisto?

Heres a few key points for this story.

Harry was once raised as a demon.

He was a contract based demon who made deals

he lost all of his memories only to regain some of them.

He does not see himself as evil but he is definitely not a good person, he is more a selfish person.

Oh and Quiet from Metal Gear Solid V is going to show up though there will be no romance with her and it is only her so it wont really be a proper crossover. By the way that game is F-ing awesome and you should all buy it

This is only the prologue so it will be short and not much happens but don't worry ill update tonight with the first proper chapter. So let the fun begin.

…

…

…

Dementors were interesting beings if one thought about them enough. They fed on happy, positive emotions and yet a spell cast from said emotions was used to drive them away. It is also said that a Dementor forces you to remember your worst memories but that is also not entirely true, there have been cases of people remembering things that they honestly had no chance of remembering. One young girl in Canada remembers the fire that took her parents lives and scarred her completely when she was only a few months old, whenever near a Dementor. What a Dementor actually does is it forces a person to relive what would be the most traumatising thing that at that moment to have ever happened to them, wether they remember it or not.

Harry remembered screams and laughter, heart wrenching, soul breaking screams of pain and misery, and cold, cruel laughter that filled his entire being with fear.

When he first encountered a Dementor for the first time all he heard was the laughter, the second time there was more Dementors and he also heard the screaming, the third time with over a hundred Dementors and the effects were more….permanent. Every night since then Harry would have nightmares over what had happened, he would hear the screaming and laughter, he would feel an insatiable hunger, see the body of the thing in front of him and he would taste it's flesh as he tore into it with abandon, he would then feel the relief of something in his stomach and that would cause him to wake up, vomiting over the edge of his bed. Every night Harry would have that dream and every night it would slowly grow in length.

After a week he saw himself pulling a pile of rocks of off the thing. After a month he heard the thing scream as it slowly died before he pulled it out of the rocks to eat it. After two months he saw himself setting a trap and watching as a seven foot tall, red skinned, red haired man with black eyes and sharp horns walked into his trap and was crushed slowly to death by the rocks.

Surprisingly it was another week before what that man was clicked for Harry. The Dursleys had just come back from church, as like every normal family they went to Church once a week, and Dudley was talking, loudly, about how Harry was a sinner and would go to hell to be tortured by demons.

Harry just ignored his cousin and the day went on much like it always did and that night when he dreamt his dream and saw the red skinned man he didn't think of him as a red skinned man but a demon and with that realization he remembered.

He remembered a tiny little boy, so sad, so alone in a small cupboard, crying over the fact that everyone hated him. He remembered begging someone, anyone to take him away from his cupboard, his relatives and worst of all he remembered getting his wish.

He remembered blinking and the next second he was in a rocky landscape with a green moon overhead, red stars and nothing in sight except for rocks, rocks and more rocks. Harry did not focus on that though, instead all he could focus on was the screaming that assaulted his ears and the laughter that caused him to curl up into a ball crying.

At the time Harry wasn't sure where he was or how he had gotten there but he did know he was stuck there. Eventually after he had cried himself out he got to his feet and slowly started to walk in a random direction, intent on finding someone, anyone to help him.

Harry eventually found a few people but every single one of them would run away once they caught sight of him.

Harry remembered eventually being able to catch something and eat it. He remembered feeling stronger as he did so and liking it so he captured more and more just to eat them.

Harry remembered eventually coming across a demon who instead of walking around naked was wearing a fancy tuxedo with a top-hat and cane, he remembered the demon introducing himself as Mephistopheles and offering to take Harry in and look after him.

And so Harry found himself being looked after by Mephistopheles and taught about the world he had found himself in. It was a Netherworld, one of many worlds in Hell where all demons and evil spirits found themselves, Mephistopheles was the ruler of this particular Netherworld and was known as The Contract Demon for his habit of making deals with almost everyone and everything.

One day, thanks to Mephistopheles teaching, Harry was able to gain control of his own Netherworld, it was a small place, only a floating castle in a void of nothingness, but it was his and Harry was it's ruler.

Slowly Harry used Mephistopheles teachings to expand his power and while he would never be considered a great power in Hell he was at least a known power.

One day he received a letter that immediately gained his attention. It was delivered by bird which was unusual, the parchment was not made from human or demon skill which was very unusual and it was for a magical school in the mortal realm.

Intrigued by the letter Harry went off to he mortal realm to speak to Albus Dumbledore, the head of this school.

Harry remembered meeting Albus, making a contract with him and then he remembered waking up in his old cupboard, not remembering anything.

That was pretty much everything that Harry remembered, there were a few bits and pieces of useless information but essentially that was it. He could not remember ANY of Mephistopheles lessons or just why the Great Demon had taken him in. He could not remember anything about the contract with Dumbledore and he could not remember any of his usable powers except for one.

With a click of his fingers Harry watched as a piece of human skin parchment appeared in his hands the word contract appeared on the top.

Harry smirked, he may not remember everything but he remembered the feeling of power he once held and this contract would help him regain that power.
