Tor is a compact, broad dwarf whose gait has the deliberate roll of a loaded ore cart, each step placed as if he were testing the floor. His beard is thick and ember-threaded, its iron rings dulled by soot; the ends are combed into two blunt wedges that rest on his breastplate. A minute of conversation brings the smell of hot stone, lamp oil, and bitter mint from his collar. He knows about the mint, and offers it when visitors cough. In a crowded room, his eyes keep returning to hinges, ceiling braces, and the feet of anyone standing near an edge. He leaves the impression of a gate that has learned to speak.

Tor is stern about schedules and unexpectedly gentle with frightened workers. He distrusts speeches, yet remembers every promise made in his hearing. In a crisis he becomes brisk and almost reassuring; in private, he is more willing to admit doubt, though rarely before the decision has been made.

Born among the Cinder-Beard families of the Basalt Spine, Tor learned to count ore loads before he could read a muster roll. He began as a bridge guard, then rose through escort work by treating maps, meal stores, and replacement winch-pins as matters of survival rather than clerical fuss. During the Great Chasm Sieges, a breach in Obsidian-Gorge's span trapped a convoy above the magma canyon while creatures surged from the lower galleries. Tor abandoned the safe command post, organized the stranded workers into a brace line, and held the damaged crossing until the last cart cleared. The decision cost lives, including his mentor, but changed his view of authority: a commander who cannot stand where the danger is has no right to price it. In the decades since, he helped unite several escort companies into the Iron-Vein League and became its Grand Marshal of the Highway Guard. He still enforces tolls and demands League certification, believing predictable passage prevents private armies from turning every bridge into a battlefield. His present strain is personal as well as political. League officers want him to authorize a permanent armed checkpoint over an old gallery whose tremors have grown more frequent. His daughter, Heshk, argues that the route should be closed until engineers understand what is shifting beneath it. Tor refuses to concede the point publicly, but has begun walking the gallery alone at dawn, listening through the soles of his boots.
