Shank is a Drow Hybrid between an Assassin and a Vampire.
He has a battle scar that causes his left eye to appear plain white, though that appears to be the only damage he has ever taken. Most enemies of his do not live to tell of him, meaning his past is a secret. The fact that is he is usually hidden in shadows and does not speak to many people does not aid him make any friends.
One thing is for sure if you see Shank: he is not the kind of person to mess with and get onto his bad side.
