Grimm is a boulder of a dwarf with skin the color of well-oiled teak and deep-set eyes like polished amber. His iron-gray beard is a marvel of engineering, braided into three massive locks that are held together by twenty-four gold rings and silver wire, which produce a low, melodic chiming sound when he speaks. His hands are surprisingly long and delicate, possessing none of the callouses typical of his kin. He moves with a slow, deliberate gravity that makes the air feel heavier when he enters a room, yet he has a contradictory habit of bouncing slightly on his heels when he sees a rare coin.
