Baelon is a demon in a more traditional sense. While you should be wary when summoning him, he's a great teacher and for a pittance (usually food) he'll help you with your homework, engineering project, or really anything to do with the physics or maths. He's too lazy to be really finicky over contract rules and trick people into getting into bad deals, but he will take advantage of anyone who tries to go over the arranged amount of time.
He has some shape shifting abilities that he uses to make his way around the material world. While there he's rather sociable, he particularly enjoys crashing parties and adding a bit of his brand of chaos to otherwise bland events.
