Eiran is a weather-browned human with a broad, weather-ready face and a patient gaze that seems to check the sky even indoors. His dark curls are cropped close at the temples but spring loose at the crown when damp. He moves with a grounded, careful pace, planting each foot as if testing a deck in rough water. A palm-sized brass barometer hangs at his chest; its glass is cloudy, and the lower rim is worn to a bright crescent where his thumb worries it. He smells distinctly of wet wool and crushed fennel, an odor he notices only when someone else mentions it.

Eiran is reassuring in a crisis but awkward when thanked, and his natural patience turns into stubborn bluntness when someone treats lives as expendable. In quiet company he is dryly funny and attentive; after a near miss, he becomes procedural, checking ropes and names until he can settle himself.

Eiran grew up hauling nets and carrying messages between the cliff villages of the western coast. At nineteen, he was aboard a supply skiff when a sudden squall overturned it near the reef. He clung to a spar for hours, listening to his younger brother call from somewhere in the dark water; by dawn, only Eiran had been found. He spent years blaming himself for choosing the safer line toward shore, until a retired lighthouse keeper named Daro taught him that survival was not a verdict on love. Eiran later joined the small shrine at Brinehush, where he learned the cleric's prayers and became a steady presence during floods and wrecks. He now tends the shrine, checks storm warnings for passing crews, and quietly searches the coast for any sign that his brother might have survived. The shrine's roof is failing, and its reeve, Kesta, wants to divert the repair fund to a private pier.
