A compact halfling with a round, expressive face and a spring-loaded way of moving, as if every joint contains a hidden mechanism. His clothes are permanently soot-stained at the cuffs, knees, and collar, yet every brass buckle is polished to a warm shine. Goggles rest on his forehead, their lenses scratched with tiny starbursts and one patched with green glass. His mischievous smile shows a chipped front tooth, while his left eyebrow is threaded with a fine copper wire that twitches whenever he lies. He smells faintly of hot metal, cardamom, and singed wool. Despite his grubby work clothes, his hands are exceptionally clean and his fingernails are painted with neat black dots for counting tool sizes. He leaves people with the impression of a cheerful child who has somehow become responsible for explosives.
