Short and brisk with quick, nervous movements that never look frantic. He keeps a shoulder-slung satchel of half-finished contraptions and a belt of tiny tools that clink like soft rain when he walks. His clothing is a collage of patched leather, brass plates, and embroidered pockets, all arranged with aesthetic fussiness. He wears circular spectacles whose lenses are layered with micro-gauges; when excited he flips down a secondary lens that glows faintly green. Unexpected element: his left sleeve is pristine and ceremonial, embroidered with a family crest, while the rest of his clothes are singed and stained from experiments.
