dimitri's a relatively young vampire (only about 130), with related war trauma and killer instincts. he's got poor impulse control when the people he loves are threatened, so it might be a good thing there aren't any of them left. he tends to be blunt with his friends and polite with his enemies, but he's not really in touch with his emotions, as he'd have to admit to having some before he could get in touch with them. he's fairly ruthless and has a self-righteous streak that can get be trouble, but is used to repressing that as part of the chain of command. he's a great ally, a terrifying enemy, and a surprisingly loyal friend.
