He's definitely a cautionary tale people tell kids. 'If you sin, you go to Hell and the devil tortures you.' Or something. But in Western literature, he's definitely described as a very handsome, smooth talking, easy going man who can talk you into just about anything before you realize what you've done. So. Check and check for our friend Lucifer, here.

[ Not that she knows for a fact he's smooth talking or easy going or that he'd try to talk her into anything, but he definitely looks the part, so. ]

You're right, though, I think he really is bored? So he made this place. I mean, what is he going to deal in here? Once we leave I assume the contract is null and void unless being the Devil means he can remember being here after he leaves.
