Dagna is a stout, powerfully built dwarven woman whose body has the compact density of a quarry pillar. Her auburn braids are thick as ship rope, soot-streaked, and tied back with heavy copper wire that has been polished by years of use. Her beard is absent, but a short fringe of copper-red whiskers lines her jaw and chin. She moves with a measured, rolling gait that suggests both a miner walking over uneven stone and a diver compensating for invisible currents. Her hands are broad, scarred, and permanently darkened at the fingertips by bronze dust. Despite her intimidating bulk and battered industrial gear, she has an unexpectedly delicate smile, almost shy, which appears whenever someone presents her with an elegant engineering problem. She leaves behind the impression of heat, pressure, and absolute reliability, like a sealed furnace door holding back an ocean.
