Prologue

''Up! Get up now!''

A pair of emerald green eyes slowly opened at hearing the screeching of the bitch who was his aunt. The eyes took his surroundings in for a moment before he muttered four words which if anyone would have heard them they wouldn't have made any sense to them, but to the young boy they made perfect sense.

''Huh it actually worked.'' He muttered as he took a moment longer to look around his new surroundings. Merlin who would have thought that one day he would be back here?

''Up!''

The boy sighed. He was more than happy the information his patron had given him had been useful and he had actually managed to take over the body of his younger and pathetically scrawny and weak self, but couldn't he have awakened in the middle of the night or something? Anything would have been better than waking up to that bitch's howling.

Despite his annoyance a grin that would have no doubt scared the other inhabitants of the house started to spread on the young boy's face. He was back. He was really back! Centuries may have passed, but it would be impossible for him not to recognise the cupboard he was is nor the screeching of his aunt.

Finally! Finally there would be something to entertain him again. The Dursleys, Snape, Dumbledore, Voldemort they were all still alive right now (well for the most part in one case)! Oh the fun he could have with them it almost made him giddily in excitement.

If anyone knew what the boy was thinking they probably thought he was mad. After all no sane person would ever get giddily at the thought of Voldemort being alive. Then again most normal people aren't centuries old either so they really couldn't judge.

Then again it was not like the boy really cared what others thought of him. After all he had committed one of the biggest taboos in the magical community just because he was bored.

Now this may sound bad, but in his defence he had been really bored. After all due to his inability to die a natural death a point in time came when he had tried his hand at practically any profession and hobby that existed in the world (and some he had come up himself) add to that the fact that he couldn't form any meaningful relationships due to the fact there just weren't that many immortals out there.

Of course there were some and Harry had met quite a number of them. Fawkes was one of them, but as he was a bird (albeit a highly magical one) conversations were out of the question, then there was Claire … he never really figured out if she was immortal or not, but as he had seen her several times over the centuries it was safe to say if she wasn't immortal then at the very least she would get very old. Unfortunately she had never really forgiven him for his actions during the third world war so whenever he met her the conversations usually were rather strained. Then there were the vampires; an entire race full of immortals. Unfortunately they didn't like him very much … this may had something to do with the fact that during one of his periods he had been extremely bored he had become a vampire hunter for a couple of decades and almost decimated their entire kind.

Looking back Harry had to smile; that had been a fun couple of decades; minimal use of his magic and mainly using a sword he had started to learn how to use a century before. He even gained a temporally companion in a rather eccentric and most definitely bloodthirsty vampire by the name of Clara. The young woman apparently had no problem with slaughtering her kin. He hadn't really pried why that was and had just enjoyed the companionship. It was a shame she died fighting a rather strong vampire by the name of Laurent Desmarais, but at least she died as she had lived; with a smile on her face.

Life after that hadn't been that interesting. Muggles kept inventing new technologies so that kept his attention to some extent. He had even held some hope he would one day be able to go to outer space, but alas it was not to be as Muggles started fighting yet again. This time it escalated even further that the fighting he had seen during the third world war and after a mere two weeks the hundred or so humans that remained could say that the fourth world war had ended.

To Harry the war was the last bit of excitement he had for a very long time. With most of the people on earth dead and large pieces of the planet utterly uninhabitable it was a very boring existence for the centuries old immortal.

Even Claire a person he had been convinced was just as immortal as he was seemed to have perished during the war and while she and he hadn't been the closest of people it had still hurt beyond belief when he realised that someone he had known for centuries was probably dead.

It had been then that his patron had appeared before him and had offered him this chance due to 'services rendered' (apparently she didn't like vampires very much. Who knew?) He had jumped at the chance and now he was here; back in the cupboard under the stairs.

The gleeful grin never left his face as he extended his hand forward and held it open. Mere moments later a piece of wood; elder wood to be precise appeared in hands.

Harry's grin grew even wider as his core resonated with the wand; he was really going to enjoy this chance and who knows maybe he would even do the right thing and kill that bitch who thought it was a good idea to reveal the magical world to the Muggles and by doing it indirectly caused the third world war and even more indirectly the far more devastating fourth one.
