Pippa Poltergeist

Backstory

Was a student at Hogwarts, in Ravenclaw House. Was exceptional at schoolwork, but loved a good joke. Was also quite eccentric. Had a strange fascination with ghosts, death, and the afterlife. One day tried an experiment to find out what was on the other side, and accidentally died in the process. When given the choice, she wanted to become a ghost. She is now best friends with Peeves, always helping him annoy the caretakers, and the Grey Lady, being one of the only people that she will talk to.
