A broad-shouldered air genasi man with softly blue-gray skin, dark teal hair that drifts as though underwater, and pale silver eyes. His clothing combines practical traveler’s layers with a reinforced leather apron, brass fittings, and numerous small tools. He stands very still when listening, but when he begins working he leans close over his inventions, filling the space around him with quiet motion, clicking tools, and the faint stir of wind. His voice is calm and warm, with a gentle breathiness beneath each word.

Mosi is patient, observant, and quietly sociable. He prefers useful conversation to small talk, but he is genuinely fascinated by how people solve problems. He treats tools with care, strangers with courtesy, and bad maps with suspicion.

Mosi was born where a highland caravan route crossed a region of strange, constant wind. His mother was a human cartographer, and his father was an air genasi guide who could read distant weather by the pressure in his bones. Mosi grew up carrying survey rods, repairing cooking stoves, and listening to travelers describe places he had never seen. He learned early that a broken wheel could strand a whole caravan, while a well-made compass could return one safely through fog, snow, or unfamiliar country. As he grew older, Mosi began building small practical devices from salvaged metal, leather, and crystal. His best invention was a palm-sized windfinder that hummed whenever it sensed a change in pressure. When a mountain expedition vanished, Mosi discovered that its final route had been altered by someone who wanted the travelers lost. He repaired what equipment he could, guided the survivors home, and kept the damaged windfinder as proof that careful craft could uncover truths that rumor concealed. Now he travels as an outlander and artificer, helping strangers on the road while searching for the person who tampered with the expedition's maps.
