Can you tell I'm a fan of Eberron. No really, can you tell? Okay yes I am. It's my favorite published D&D setting so far. It is also true that Hogwarts exists in Eberron. Floating towers of magical academies! The bowels of which are filled with strange, delightful, and mysterious things. Of course there's no explicit call out for a disgraced member of the academy who tried to live forever by splitting up his soul. That said, there isn't any reason there couldn't be one. If you don't believe that there's a place for everything in Eberron, consider this. In Karrnath there is an alchemist. She makes the most interesting magical item. A piece of paper that shows the viewer whatever it is they are expecting to see. It's most used as a magical means of forging traveling papers. Yes, that's right. Eberron has psychic paper. You can't tell me there isn't a mad man in a blue box flying around the planes in Eberron.
