Salla looks as if the tide has been sanding him smooth for years: weather-rough skin with salt-dry patches at the temples, dark curls clumped into ropey twists, and a broad, steady face that seems to be listening even when he is looking away. He moves with a boatman's careful economy, knees flexing as if the ground might suddenly roll. His unexpected detail is a neat little braid threaded with bright red glass beads, a keepsake he tends with the care of a jeweler despite his rope-burned hands and patched work clothes. People notice his breath first: a measured intake through the nose, then a faint rattle in his throat, like water slipping through stones.

Salla is patient with frightened people but impatient with anyone treating danger as a bargaining chip. He can be warmly funny while mending gear, then sharply unsentimental when a rescue is underway. He wants his mother's approval more than he admits, yet resents every expectation she places on him.

Salla grew up among the broken seawalls of a harbor where old siren families once commanded safe passage with song and threat. His mother, Rhoswen, taught him the fragments of their ancestral call and expected him to restore that authority. As a young man, Salla joined a salvage crew, believing he could earn his place by bringing up relics from a wreck field. During a winter gale, the crew's captain ordered him to abandon trapped deckhands and save the cargo. Salla disobeyed, cut the cargo loose, and dragged three people through the surf; one of them was Ezzek, who has remained his friend and occasional partner in rescue work. The wreck cost Salla his crew's trust and left him convinced that inherited power is worth nothing if it cannot protect anyone. Now he runs an informal rescue service from a battered skiff, while Rhoswen presses him to reclaim the sirens' old authority. He is also trying to find steady work before the harbor's new breakwater closes the narrow channel he uses to reach stranded boats.
