Jameson is a lean, broad-shouldered fire genasi with ember-red skin, dark hair that glows faintly at the tips, and eyes like banked coals. Wisps of smoke curl from his ears when he is angry or excited. He wears a weathered sailor's coat over fitted leather armor, a red sash marked with faded naval knots, and several brass charms taken from ships he has outlived. His hands are calloused from rope, rigging, and years of working lockpicks in cramped cabins.

Charming, opportunistic, and restless, Jameson treats every conversation like a negotiation and every locked door like a personal insult. He is fond of tall tales, quick with a grin, and slow to admit fear. Beneath his swagger is a fiercely loyal survivor who still measures people by whether they stand beside their crew when the ship is sinking.

Jameson was born during a lightning storm aboard a merchant vessel, the son of a human deckhand and an elemental wanderer who vanished before he could remember her face. The crew treated the infant fire genasi as an omen, but Captain Mara Vey took him in and raised him among the rigging, salt spray, and whispered deals of the sea. Jameson became a pirate in everything but name, learning to climb faster than anyone aboard, slip through barred doors, and smile convincingly while hiding a knife behind his back. By adulthood, he was the captain's most trusted infiltrator and the crew's best gambler.
