A bit like it is where I'm from. Some darker witches and wizards form after they've come obsessed with the actual power they can wield. Others are prejudiced against witches and wizards who are not purebloods, or at least not half. They hate Muggles (non magic folk). There are several who would not do well in this environment. Honestly, evil aside, I'd like to see a few of them show up here, see they are outnumbered 500 to 1, just so I could watch them squirm for a bit.
Wait... Snow as in the Snow White and Charming as in the Prince Charming?!?!
