Rosen Krantz is a man with a dark olive complexion and dark brown, nearly black hair that he keeps slicked back. He has green-grey eyes, and a hint of too many late nights. He is of a lanky build, with what some have called "piano playing hands".

He is fond of accruing wealth, getting away by the skin of his teeth, and cheap, greasy meals.

He dislikes needless killing, the wealthy/powerful, and terrible risk/reward ratios.
