DISCLAIMER: NAMCO was in possession of Tales of the Abyss to my knowledge not me, and J.K. Rowling still has a stranglehold on Harry Potter. So no suing.
He always felt as if there was more to life, like there was some other purpose. Even as a small child when he didn't even know his real name and was just called 'boy' and 'freak'. As if his life was meant for something, for someone else to call upon and command. It might have been why he never really complained when he was ordered to do the housework, and only really complained about the Harry Hunting and not being wanted. After all if he proved he was useful enough they would want him, maybe even accept him and tolerate him. Even as a distant part wanted and yearned to be loved by the family that he lived with, to be considered more then an interloper in their home.
When the odd letter written in green ink addressed to him had arrived and the large man Hagrid had told him about magic, and his parents…he had allowed the hope of finding one to want him and accept him grow once more in him. Even as the goblins looked at him speculatively and Ollivandar had seemed as if he wanted to say something but stopped when his eyes flicked over to Hagrid. Seeming to know something he should know but no one else was supposed to know.
A secret of what was missing in his life.
He hadn't had a chance to find out what it was the wandmaker knew. Not that summer, as the rest of the month was spent locked in Dudley's second bedroom with his books, or doing chores. Then it slipped to the back of his mind as he entered Hogwarts for his first year of magical learning. Something that felt so natural to do, but in a way wrong to be the one commanding the energy within him to do as he bid as if he should be only using it by the orders of someone else. Theoretical work quickly became the bane of his existence. He just couldn't figure out how to put down what he knew in some deeper part of himself into words that would make sense to everyone else. It was frustrating, especially when Hermione and Ron got aggravated with him when he couldn't tell them why he could do the spells so easily. Heaven forbid they ever find out he didn't really need the wand to use magic.
Such oddness aside his first year was…lacking. Oh he was happy to have people his own age to talk to without Dudley there to keep them away, and the whole fiasco with the Philosopher Stone was unusual, but the feeling of missing something still persisted. The feeling becoming an odd sort of ache that after a while he forgot about, the way one would ignore a throbbing bruise or injury if they have it for long and constant enough. It was also easier to ignore during his second year with the threat of being petrified or killed hanging over everyone's head and the whole heir of Slytherin business he had to put up with.
The summer before his third year brought about a sudden clarity and answer to what he was missing.
Harry Potter spending his summer in Diagon Alley had not been kept as any sort of secret. Though, considering how the wizarding world acted in regards to him he would have to be under enough glamours to shimmer with magic to keep the boy-who-lived spotters from noticing him. So it wasn't all that odd for people to stop and stare when a mop of messy black/red/gold hair and lightening bolt shaped scar upon a young preteen's brow. Many did so because of what that scar meant, while a few did so because of the odd coloration, especially those who looked and compared the ratio of black hair to red and gold each consecutive year since the first covert photograph of the boy at about the age of four and now could see that the Potter hair was being overtaken by the red/gold that was but was not the same as his muggleborn mother.
However, this particular day, before the yearly Hogwarts letters were sent out. The few denizens of Diagon Alley were treated to a sight that would cause many to have slight brain combustions as two almost identical boys looked at one another from opposite ends of the Alley.
One was small, almost elfin like in bone structure (Years of near starvation and grueling physical labor), clunky glasses (Gotten from a yard sale), large green eyes that seemed to glow, black/red/gold hair like a flame when the light hit it, frayed tattered clothing, and a lightening bolt shaped scar. The other was taller and more fit looking, (From being allowed three squared meals a day and exercise) face devoid of glasses (He had contacts), the same shade of green eyes as the other that seemed darker even as they glowed as well, dark almost black red/crimson/gold hair, decent clothing that seemed almost like a military uniform…and a lightening bolt shaped scar.
No one in Diagon Alley had time to figure out what was going on or what this meant, before Harry Potter seemed to have been hit with a sticking charm if the way he grasped onto the almost look alike as he did. The shock only compounding more as Ollivander actually left his shop and ushered the two within, right before the open sign changed to close and the windows darkened so none could see in.
What many did not realize that this was an event that would bring about the remembrance of things long past, of a process called replication, and the results called Replicas, and of Fonons and the aspects of the seven frequencies that govern the natural world; and of the true origins of magic when it was known as Artes.
For a certain Headmaster and his Greater Good, and a prophecy possibly on the verge of being obsolete. He would find out just how much damage to his plans there would be for never figuring out he was grooming a Replica and not the real Harry Potter to be his martyr.
NOTES: Something that came about when looking for HP/ToA fanfics and not finding any that fit with what I was craving and then having piano/girl version of Karma pop up on my playlist made me go "huh". I'm planning on following through on this idea but maybe this could maybe have others follow my line of thinking and bring forth more fics for me to read and thus procrastinate my time with. This is mostly just a rough summary of what would be a very long chaptered story that I would seriously need to plan out considering the various elements of both ToA and HP that I would have to mesh together.
After all there's a really good what if to tie the two aspects together without doing reincarnation/toss one set of people into the other world. The ToA part spent the entire game pretty much fighting against the Score and thus being told how to live and die, and Harry Potter pretty much revolves around Harry being manipulated/set up/right place right time to live and 'die' by the whims of a very vague and, in my opinion, stupid prophecy. And to me prophecies are just like the Score and considering how fucked up Aulderant got due to people blindly following what the Powers That Be (Lorelei) as they tell them how and what to do even how and when to die, I could see wizards doing the same damn thing only with Seers and Prophecy orbs. Thus my mind went 'well, what if earth is nothing more then Aulderant after everything was said and done?' History can be lost, and with the way wizards like to hide themselves from muggles it wouldn't be too much of a stretch to think that somewhere Fon Arte users, especially Seventh Fonists would want to isolate themselves from the rest of the world if there was still those desperate enough to believe a new Score or something similar was the only way to live. So Lorelei, and Efreet, Gnome, Undine, etc. would be still out and about the world and when it became apparent that wizards were finding a way to make their own version of the Score through Seers and such...well why not attempt the same problem solving tool that was used the last time? Only this time the perfect isofones would have time and not a full blown Score to contend with in stopping it.
I mean, wizards have things like Polyjuice and simulacrums/golems, it would only take someone dedicated enough to figure out how to make the leap from that to creating a copy of someone and thus recreate the Replica aspect of ToA into the HP world. And at such a time that a well meaning individual may decide to replicate the child savior of the wizarding world, for his own protection of course.
