Vulcan is a broad red metallic dragonborn whose scales look like hammered copper coated in lacquered ember, each one catching the light as if it were a coin turned in a fire. His lower jaw bears a black iron prosthetic fused so neatly to bone that it seems grown there, and when he speaks it clicks softly like a smith's tongs. One horn is intact and polished to a dark wine sheen, while the other is chipped and bound with silver wire. He walks with the measured weight of a man who once carried siege armor, yet his hands move with startling delicacy at the forge. The contradiction that makes him unforgettable is his apron, patched from soot-stiff leather and stitched with bright floral thread by his missing wife.
