Disclaimer: I don't own or make a profit from Harry Potter or Marvel Comics. This is a fan made work.
Pairing: Hannah/Neville-I think. Not sure yet, still considering my options. I'm leaning toward Luna or Hermione for Harry. Any opinion with good reasoning to back it up will be considered. Maybe Harry and two witches.
Spoilers: Up through the second limited series for Domino. I am generally of the opinion that the last decade of Marvel comics didn't happen. I like X-Force, I miss X-Force and Excalibur and X-Factor, and the man Tony Stark used to be. I even miss the old Peter Parker. As a result, though there will be spoilers for various things here and there, this takes place during the nineties, continuity wise. Everything for Harry Potter, because I don't know yet what I will and won't include.
Prologue
Dorea Beatrice Potter, nee Black, had never been the sanest of women. Not that her husband, Charlus Potter had cared about his wife's sanity. This was mostly because her insanity was not hereditary. After all, one wouldn't want an insane heir.
While the cause of Dorea's insanity was questionable, it was likely the result of a number of highly traumatic incidents in her youth. Witnessing one's older brother being murdered for the crime of being a squib had doubtless been horrifying for an eight year old. However, it was generally agreed-by Dorea's brother and sister, at least-that the sight of what had been done to their cousin, Cedrella, for marrying Septimus Weasley had been the event to push Dorea over the proverbial edge.
After many years of trying for a child, Dorea and Charlus had been overjoyed at the birth of their twins. James was everything one could want in an heir-healthy and using accidental magic within his first week of life. His twin sister, on the other hand, never showed any signs of magic.
Like several other members of the Black family, she was a seer. Even before her daughter had been born, Dorea had known that the girl would be a squib. But Dorea had allowed her husband to convince her that perhaps she'd been mistaken. Perhaps their daughter was merely a late bloomer or her accidental magic was so subtle that they didn't notice. After all, the girl had always been unusually lucky-even for a witch.
Though not precisely in touch with the same reality as the rest of the world, Dorea was not, in fact, pushed over the so-called edge until the day James received his first Hogwarts letter. In all the excitement, it had taken several minutes for James to notice that his sister had not received a Hogwarts letter and even longer for him to notice the devastated look upon his mother's face.
It was not until years after the fact that James questioned what had happened to his sister while he was away at his first year of Hogwarts. In fact, he didn't even question his sister's sudden illness and death until after his marriage to Lily. But by that time, Charlus and Dorea had seemingly been murdered by Death Eaters-although they never did find Dorea's body.
