Chapter One:
Meet Harry

My name is Harry Potter, my age is in the thousands of years, and I still look like im 20. This is my curse, my immortality. During my youth, I was a special human, I was a wizard. During this time frame Wizards and Witches feared muggles, no magic Humans, and hid all traces of magic. It was a shock when a half giant knocked my door down as I was muggle raised, to take me to a magical boarding school. Hogwarts.

During my Years at Hogwarts, I made great Friends, and eventually met who would become my wife. However it wasn't all happy, far from it. Each year a Dark Wizard Lord known as Voldemort tried to kill me. Each time he failed but the years were crazy and hectic. Ah its been so long, Hogwarts, the years weren't kind and now its not even ruins.

Anyway, during my last two years at Hogwarts, Voldemort kicked his operations into overdrive, and the Wizarding World was at War. Many died, I killed Voldemort, and was soon cursed.

The three Hollows, all held makes the wizard a master of death according to Wizard Lore. How wrong they were. As the years past I ended up burying my friends, who grew old and grey while I stayed young, my wife and children and great grand children. If this is a gift its one I wouldn't wish on my worse enemies.

After a while I left my descendants to their own fate, and left the Potter name behind. I travelled the world, learning ancient and new magical arts. After several hundred years of study and practice, I knew all but the darkest of arts. Which I refused to learn, the idea of a ever living dark lord, scared me away, I couldn't risk it, but the dark arts I did learn were once known as battle magic.

Men who kill to defend their homes aren't monsters. Men who take any pleasure in it are.

As I started to learn Muggle science, my mind was blown. Thousands of years of magic, was nothing compared to the massive amount of knowledge the Muggles had, from Martial Arts to Chaos theory science.

During this time I watched the world Rip itself apart, Muggle weapons capable of wiping out entire countries. Dark Lords who managed to learn demonic summoning and more evil spells become more and more deadly.

By this time, years of hiding my emotions and solitude, I didn't care. I watched the world cry, and distort under the various energies ripping it apart, from Muggle science to magic.

To this day I still don't understand what happened next, the world was angry, the apocalypse came. The world fought back it seemed, Natural disasters from earthquakes that flattened citys and Volcano's appearing to burn everything around them in molten fury. The world changed. Man died.

Or so I thought. The world had changed, and so had man, the remnants built afresh, magic and science worked together to advance man. Magicals and Muggles worked together, and moved forward.

In time the world was renamed Earthland, and countries formed. I watched again as wars spread, but something rose to keep peace, and was more successful than anything in the past. The Magic council.

Why technically not ruling the countries, they ruled the wizard guilds, and these wizards were a lot stronger than the ones of my Era. I learned this new magic as I could, but despite not being hidden, the openness kept him out better than any vault. I learnt little.

After so many years of isolation, I was terrified of human interaction. While im on my own I laugh at it, the sheer destructive magic I know plus the fact I can't easily die, and im scared? Huh irony's a bitch.

So I hid in a mountain, keeping to myself and just ignoring the world, I lost track of time, and I started creating new magics to keep me entertained, from magical items to new spells. And time flew, until the Red Haired Demoness came.

-IWS-IWS-IWS-IWS-IWS-

I was sat at a table, books of various size and colors surrounded me. I was working on a new idea for some magical gear from a truly ancient piece of lore, Nordic in origin to be specific. I've already made some weird stuff, like Zeus' thunder bolt. That was some tricky magic. Sure the spell to do a similar thing was easy, but an item was a pain in the ass.

Have you ever tried keeping lightning in one place?

Either way I had trouble concentrating because the cave he made his home was shaking, either a strong wizard was training nearby or it was one of those damn monsters fighting. Maybe it's a wizard and monster fighting each other, who knows, who cares.

The wards keep everyone out and nobody can find this place. Too bad Hary didn't take into account a giant monstrous rhino being thrown into a mountain side. Seriously what the Fuck? A notice me not ward, a modified fidileus to hide one person, and a strong magical barrier. Once again, What the fuck.

That was my exact words as the monster came flying through and smashed into me sending me flying into the opposite wall.

My last sight was a person walking over the now defeated monster, covered in armour with long red hair.

-IWS-IWS-IWS-IWS-IWS-

My eyes fluttered open, the world was a mess without my glasses, but the sheer brightness and smell of disinfectant made me think of a hospital room or ward. The lack of sound of other humans made him think it was a room.

Hearing a gasp he turned to look where the noise come from, and was frozen, despite the fuzziness he could still tell it was a human, thankfully they quickly left.

Conjuring a pair of glasses, they wouldn't last long but long enough till he found his old glasses, he looked around. The room was rather plain, besides the bed he was on and a side table and chair it was rather barren, a door to some room, one that exited into a hallway and a window with curtains.

Looking outside the window he noticed a Human city, and despite his anxiety of being near humans, he had to admit it looked amazing.

Hearing the door open, a brown haired female nurse entered, evident by her clothes, and a woman with red hair and wearing some type of armor. For some reason she looked familiar.

With his head still hurting he couldn't focus his occulemency to bring up any memories of her, so he decided to ignore that nagging feeling for now.

The nurse began to check some things such as his heartbeat and temperature, and other medical stuff. Harry had to take his focus away from her as the red head starting to talk.

"My name is Erza, from Fairy tail, I brought you to the hospital." Wait I remember, was there a monster as well? "You was injured and bleeding as I fought a monster terrorising a town near your… cave."

'Wait, I was dying and not by her hand, and she saved me…. of FUCK! I hate life debts, evil things.'í looking back at the now known Erza, she was stood there, and I noticed something, a mark on her shoulder. 'So she's a part of a guild, it might be easier than I thought to fix this life debt, there always in dangerous situations right?'

"Thanks I guess, but there's something I need to tell you, once the nurse leaves." I replied, her eyebrow arched, but nodded and I took a better look at her, despite her armor you can easily tell she was a beauty, curves in all the right places and large breasts.

As the Nurse left I was about to begin talking, but she beat me to the point.

"Before you start, can I ask why there is a magical bond between us?" great she noticed it, I sighed, no lies here then.

"Well, it's hard to explain in full, but simply it's a life debt, you saved my live and unless I save yours, I got to do anything you ask near enough. If you word it correctly I cant even refuse. As for how and why it formed, I'll explain later." Well at least she looks as shocked as I am, if judging her face is any indication.

"Slavery?" She asked, sounding very tense.

"In a sense yes, in a way No, consider a place in between Slave and Butler. Something's I can't refuse, some I can, most of the ones that I can refuse or such as sexual demands and other explicit things." Her face blushed slightly and I swear she looked at my naked chest.

I still practiced the martial arts I learnt so I knew I had a good body, despite the scars.

"Well, I'll, erm, go ask the nurse if you can leave and we can talk more." She turned and left.

I breathed out in relief. God bless basis occlumency, my nervousness around humans didn't come out, and I didn't stumble upon any words, who knows, maybe this fear is all in my head?

AN: So that's the first chapter, Some things may or may not fit Cannon Harry Potter, Or Fairy tail, but remember its essentially AU, so feel free to point it out in case I made a mistake, but don't be insulting about it.

Also please excuse any OCness in characters, I will do my best to emulate them, as best I believe the will react to situations.

AND REMEMBER DON'T MENTION IMMORTALITY IN REVIEWS
