Sam is a slight tiefling girl with rust-red skin that looks almost copper under lamplight. Her horns curl backward close to her skull like unfinished ram horns, their ridges polished smooth where she absentmindedly rubs them. She moves with a quick, side-stepping gait, always favoring her left foot because the right sole is thick with callus from climbing roofs barefoot. Her fingers are narrow and permanently darkened around the nails by soot, candle wax, and old berry ink. The first thing most people notice is her tail, which never quite stops moving. It hooks around chair legs, taps out rhythms, and occasionally steals food from a plate without Sam seeming to notice. Despite her devilish appearance and sharp little teeth, she has an unexpectedly solemn face when listening to prayers, as though she is the oldest person in the room.
