Compact but broad-shouldered dwarf wearing a heavy, soot-streaked leather apron reinforced with hammered metal plates. A brass-faced respirator sits over his mouth and a flip-up crystal face shield rings his square beard with a faint blue glow. Both gauntlets are studded with tiny screwdrivers and sighting lenses. His helmet bears the dulled crest of the old garrison he served with, bent where it took a glancing blow. When he moves he stomps with precise, mechanical rhythm, like someone counting measures; when he is relaxed he absentmindedly polishes a small pocket gear that never leaves his palm. Unexpected element: beneath the industrial PPE he wears a faded ceremonial scarf embroidered in colors of a long-vanished mountain clan, which he smooths reverently at odd private moments.
