Short and squat as any dwarf, but moved by a restless energy. Tessa wears a tangled crown of copper wiring and a pair of scorched goggles perched on her forehead. Her hands are perpetually smudged with oil that never fully washes away. Her boots clink with small brass plates and hidden gears that chime like distant clockwork when she walks. An odd contrast shows in the way she keeps a neat braided beard ribbon while her apron is permanently stained and frayed. When she examines a device she becomes unnervingly still and soft spoken, as if listening to gear-speech only she can hear.
