So this is Adrian Ivashkov from Vampire Academy/Bloodlines. He's an irreverent Moroi (good vampires) party boy who is trying to ignore the fact that his Spirit magic is eating him from the inside out and is probably going to drive him insane.
Despite his outer persona, he's actually a really sweet and sensitive guy. Good luck seeing that, though!
He's from mid-Golden Lily, right after Sydney takes him to see his dad in San Diego, so he's a bit of a mess at the moment.
