"Yeah, The Crescent.  I didn't know about him until after the first time he took over my body.  It turns out that he was a wolf who tormented small animals for fun.  When he died, his spirit was trapped here, only appearing every crescent moon.  Obviously, that's where he got his name.  Of course back then, I wouldn't have known that he just wanted my body to keep doing what he liked most when he was still alive."
