My Oblivion PC. He's pretty generically elfy-looking. And by generically elfy-looking I mean he looks like a woman. Because elves look like women. I like making fun of elves.
He's the type of guy who'll be all polite and friendly right up until he receives the order to kill you, and he won't stop until you are dead. He has no honor, no loyalty except to the Dark Brotherhood, and a compulsion to pick every lock he sees. But other than that, he's a nice enough chap.
He's a neurotic assassin with compulsions to neatly and perfectly arrange all his books on his bookshelf, and he likes following orders, I guess. XD
