Standing over seven feet tall, Thistle possesses the wide, pink-tinted nose and long, velvet-textured ears of his kin. His skin resembles wet river clay in color and is often dusted with a fine layer of iridescent fungal spores that drift like glitter in the light. Contradicting his earthy, moss-covered exterior, he wears a meticulously starched and bleached white linen collar with a silk cravat. He moves with a heavy, rhythmic grace, though his large, calloused hands are prone to sudden, bird-like twitches when he is not holding a surgical tool.
