Dargoth (rule 63) (Patreon)

"A metal band the color of copper crosses Dargoth’s head, covers his cheekbones, vanishes beneath his gray-grizzled chin. A latitudinal band passes above his brows, over his temples, meets at the back of his skull. His eyes are wide, the sclera yellow and the irises red. His lower jaw makes a constant chewing motion as he rolls forward, and his teeth are long shadows. His head sways from side to side upon its twenty inches of neck. His shoulders are three feet in width, giving him the appearance of an inverted triangle, for his sides taper sharply to meet with his segmented chassis, which begins where the flesh stops. His wheels turn slowly, the left rear one squeaking with each revolution. His arms hang a full four and a half feet, so that his fingertips barely brush the floor. Four short, sharp metal legs are folded upward along his flat sides. The razors come erect on his back, fall again, as he moves. The eight-foot whip that is his tail uncoils behind him as he comes to a halt before the throne."
