Orius
Unrepentant DM Supremacist
A perfect fit. I like to dm arcane characters because it makes for a challenge. As for power hungry. You'll prolly have a great time dealing with the aristocracy.
I'll probably just go with a vanilla human wizard, it's been a while since I've played and like I said I've never done a message board game, so I want to keep it simple.
Dealing with the aristocracy in this case is more along the lines of steal as many of their secrets as possible to further my own power and ambitions. This is a character who serves no one but himself, though has no qualms against working with anyone else interested in crushing this vampire aristocracy. Possibly he might side with the aristocracy if it furthered his ambitions, but not as a slave or a servant.
