Thistle is a towering figure standing over seven feet tall, with thick grey-blue skin that has the texture of wet river stone. His frame is broad and heavy, yet he moves with a rhythmic, swaying gait that suggests a tree in a light breeze. A dense colony of iridescent, violet-colored lichen grows across his shoulders and down his spine, pulsing faintly in dark environments. His face is wide with a flat, bovine nose and large, expressive ears that twitch when he is agitated. The most jarring element of his presence is his scent; despite his proximity to decay, he smells intensely of expensive, cloying lilac and jasmine perfume.
