Oru has the compact, weather-set bearing of someone who has spent decades keeping his feet on slick harbor stones. Salt has roughened his bronze-brown skin into a fine, dry grain across his cheeks and brow, while the creases beside his mouth remain deep and mobile. His broad palms are ridged with pale callus from hauling mooring lines, and he turns them upward when asking disputants to pause. Close-cropped charcoal hair is combed back from a high forehead; a faint pearly sheen along his temples catches the light when he is damp. He walks with a small, steady roll, as if balancing on a deck even on dry ground. Unexpectedly, he keeps a tiny clay pot of mint tucked into his belt and fusses over it between negotiations.

Oru is patient enough to let an angry person finish and proud enough to challenge them once they do. He dislikes spectacle but can command a room when lives are at stake. In private he is wry and fond of small comforts; under pressure he becomes exacting, repeating a promise until its owner either accepts it or withdraws it.

Oru was born in a Sirenborn net-mender's household on the narrow spit between two coastal towns that fought over fishing grounds and the right to levy harbor tolls. As a young dock runner, he carried messages between the towns and learned that each side remembered the same drowning differently. The turning point came when a storm wrecked a grain barge during a tense standoff. Oru climbed onto the half-submerged wreck and repeated both captains' own words back to them, preserving their cadence until they recognized the shared grief underneath their accusations. The captains ordered rescue boats out, and a generation of feuding began to end. Oru became a mediator, famous for refrains that let people hear their own promises clearly. His most trusted companion is Berek, a former rival pilot who now challenges his compromises in private. Tamsin, a young harbor clerk, has taken to following him and insists that peace must include the workers who unload the ships. Oru is currently trying to prevent a new toll dispute from becoming a naval blockade, while his failing hearing in one ear makes crowded negotiations increasingly difficult.
