I’m considering making my second character a human, I have a general character theme going, but I have two questions.

Is there an existing Inqusitorial/Witch-Hunter type group? Doesn’t have to be an official or sanctioned group or anything, I just wanna get my Warhammer references on.

Is there someone who is willing to give me a brief rundown on the main human ‘cultures’? I don’t know much beyond the fact I’ve seen fantasy-frenchmen and fantasy-germans running around sometimes.
