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 wears a dark grey coat with a crimson lining, rhomboid silver buttons, and dark fur trim around the collar; a grey vest with a darker grey button-up shirt beneath.
