A wiry, perpetually scruffy human man whose body seems assembled from sharp angles, old bruises, and stubborn momentum. His dark hair is wind-swept even in sealed tunnels, as though some private storm follows him underground. A faint silver aether-burn scar tracks from beneath his left ear across the hinge of his jaw, gleaming when he turns toward conduit light. His cynical eyes are nearly black, but flecks of amber appear in them when he is calculating a route or spotting a lie. He moves with a loose, off-balance gait that suddenly becomes startlingly precise when danger strikes. Despite his grime-streaked face, cracked knuckles, and perpetually exhausted appearance, he keeps one immaculate white cuff visible beneath his coat, an absurdly elegant contradiction that suggests either vanity or mourning.
