I'm going for a rather traditional stance on non-humans for this one. That is, they aren't necessarily evil, but they're certainly chaotic, since their morality is incomparable. The relationship they have with humans are either as familiars (again, in the traditional sense, not the master-servant one) or adversaries. Of course that isn't to say that you can't have an inhuman character, it's just that most of the time non-human characters already [i]have[/i] magic they're contented with.

Most likely characters that aren't human are changelings or demi's. Then again, it also depends on the [i]kind[/i] of creature, since some of them are rather human like in lore. You should probably PM the details.
