Wriothesley has tufted black hair with grey streaks, pale grey eyes, and pale skin. He bears a scar beneath his right eye; three scars extending from high on his neck down to his mid-chest, with one on the right, one on the left, and one along the midline; and scars on his left and right forearms. He dresses in a dark dress coat with chains and large platform boots. He is serious about his work, but it also down to earth and very charming. He spends his time hiding away in his office.
