A compact male halfling with warm brown skin, a broad expressive face, and thick black curls usually tied back with a faded green cord. He dresses in a well-fitted leather jerkin beneath a weather-stained traveling coat, with soft boots built for quiet movement. His most noticeable habit is the way he checks the small brass clasp at his throat whenever he enters a room, leaves a room, or hears an unfamiliar voice. He stands close when speaking, often just inside another person's comfortable distance, as though every conversation is a secret exchange.

Warm, observant, and disarmingly conversational, Oluwaseyi treats every stranger as a puzzle worth solving. He is generous with food, careful with promises, and much braver when protecting someone smaller or more frightened than himself. He dislikes needless cruelty but has a professional appreciation for clever deception.

Oluwaseyi Mirembe grew up among the halfling couriers, gamblers, and market porters of a crowded riverside district. His mother kept accounts for a smuggling ring, while his uncle taught him the practical arts of slipping through crowds, opening stubborn locks, and recognizing which guards were more interested in their supper than their duty. Oluwaseyi learned early that small hands were useful, but a calm face and a good memory were what kept a person alive. He became a runner for the ring, carrying messages in the clasps and hems of ordinary clothing, until he discovered that his employers were selling names of desperate families to bounty hunters.
