A small, wiry boy who seems to move in two rhythms at once, half skitter and half glide. His face is all sharp elbows and quick expressions, with soot often smeared across one cheek as if he has been caught mid-escape. He wears a patched coat cut from three different adult garments, but the lining is unexpectedly fine silk, stolen from a noble's chapel cloak and kept for luck. His hands are quick, nicked, and surprisingly careful, with fingertips stained by ink, candle wax, and chimney ash. When he thinks no one is watching, he stands very still, almost ceremonial, like a street urchin pretending to be a statue.
