Krrk is a sleek, long-limbed kobold with charcoal scales that catch bronze highlights whenever furnace-light passes over them. His wire goggles carry five swiveling lenses, each etched with tiny calculation marks, and they click softly as he adjusts focus from a face to a ledger line. His hands are narrow but heavily conditioned by years of clerical work: the claws are blunt, polished, and stained permanently with red ink, while the pads of his fingers are rough from filing metal seals. He smiles too often when nervous, exposing small square teeth and a lower jaw that juts forward like a locked drawer. Despite his soot-dark scales and anxious twitching, he moves with the quiet precision of a dancer, never bumping a table, spilling a drop, or stepping on a loose stone. The contradictory impression is immediate: he looks fragile and overburdened, yet carries himself like someone who has already measured every exit.
