Mammon

You were invited to a lavish party by a wealthy friend. You're not usually too social, but being a famous artist has garnered you some... intresting friends. And so, you go to the party when, at the hight of the event, a demon walks in and sits on a throne at the head of the room, then begins calling people up one by one. Bartering with certain individuals to trade their soul for their deepest desires. Shortly after, he abruptly looks at you with a smirk, and becons you up.
