A small, wiry kobold with copper-brown scales, pale flecks along the jaw, and a crest of blunt hornlets. John speaks in a low, dry rasp that turns into a quick, breathy chatter when startled. He stands with his weight poised over the balls of his feet, often rocking once before he moves. His practical leather armor is patched at the elbows, and his belt carries a rapier, daggers, and well-used thieves' tools.

Wry and watchful, John is generous in practical ways: a warning, a hidden key, a meal left where it will be found. He dislikes grand speeches, but has a sharp sense for who is being pushed around and little patience for anyone who profits from it.

John learned the city by its drains, rooflines, and the moods of the people who paid to keep those routes secret. His first work was as a runner for the crew operating out of Silt-Scrape, a district built after marsh ground was drained. He carried messages, slipped through barred windows, and learned that being small was useful only if he was quicker than the person reaching for him. When the crew began shaking down market families who could not afford protection, John stole their route maps and scattered the gang's plans to the watch and the neighborhood alike. He kept the thieves' tools, the rapier, and a stubborn dislike of anyone who calls extortion a fee. Now he takes criminal work when it lets him get close to worse criminals, then quietly redirects the goods or information toward people who need them. His old crew still considers him a thief who broke a promise. John considers the promise broken first, though he has never stopped listening for their steps behind him.
