Captain Thrain Stone-Shield is a broad, square-built dwarf whose presence feels less like that of a soldier and more like a load-bearing pillar that learned to walk. His beard is iron-gray, tightly braided with copper wire and blackened furnace thread, and the lower half is singed into uneven curls from decades beside open smelters. One eye is living hazel, sharp and suspicious. The other is a brass-reinforced ocular plate set into scar tissue, its tiny shutters clicking faintly whenever it focuses. His left arm is puckered with old burns and crossed by thick surgical seams, making the limb look jointed from hammered leather. He walks with a heavy, measured tread, yet can pivot with startling speed when danger appears. The contradictory impression is unmistakable: he looks brutally immovable, but moves like a veteran dancer who knows exactly where every foot must land. He smells faintly of coal dust, rosemary salve, and hot metal.
