Ruzs has the sun-browned look of someone who has spent years on open decks, with a strong nose, a wide grin, and a face that seems to challenge the room to keep up. His dark hair is tousled beneath a battered orange tricorne hat, its brim pinned with two small white feathers. A sleeveless rust-red coat hangs open over a black sash and a chain of small brass charms. His hands are unusually memorable: the fingertips are glossy and faintly callused, as if years of handling hot iron have polished them. He walks with a loose, rolling sailor's gait, but can stop so abruptly that his coat keeps swaying after he does. He leaves an impression of careless heat held under deliberate control.

Ruzs is generous with food, information, and second chances, but not with trust. In calm company he is mischievous and enjoys making himself the butt of a joke; under pressure he becomes precise, watchful, and almost impossible to distract. He wants people to feel safe around him, yet his readiness to take over a crisis can make them feel managed instead.

Ruzs grew up aboard a salvage barge that worked the reefs outside the port of Gullwash, where he learned knots, weather, and how to keep a furnace alive in a rolling hold. His father, Draz, taught him to repair engines; his mother, Binti, taught him that a crew is only as safe as its least-heard member. At seventeen, a fire broke out in the barge's sealed powder room. Ruzs's magic awakened while he tried to hold the flames away from trapped shipmates. He saved most of the crew, but the blast destroyed their vessel and killed his father. That failure changed his instinct to rush toward danger into a habit of counting exits first. He later joined a privateer crew, then left when its captain began selling rescued villagers to pay a debt. Now he ferries refugees, hunts the former captain's informants, and searches for a missing survivor from the barge disaster. He sends regular money to his mother, who believes he is still doing ordinary salvage work.
