Not sure if he's the best fit, but I'd love to see what sorts of magic he could divine from Ataraxion's alien flora. There are a few HP wizards who are much younger, so I don't know how they'd take to another wizard from a different canon! The game itself is quite good for LCW's or canons folks aren't familiar with, though any non-human characters have to be humanized--don't think that's an issue he'd run into though.

In short, his skills might be useful and he sounds wonderfully eccentric and interesting.
