Ollo is a compact, broad-backed person with the sturdy proportions of someone who has hauled wet planks for decades. Their skin is deep brown, rubbed pale at the knuckles by salt and work; their dark hair is cut close at the sides and kept in a stiff, uneven crest with pine pitch. Their eyes are warm hazel, but rarely settle on a face: within a minute, most people notice that Ollo is studying hinges, rafters, door bars, and the seams between floorboards. They move with a boatwright's cautious economy, testing each step as if the ground might roll. Unexpectedly, they maintain a tiny, immaculate garden of bitter herbs in a cracked teacup, carried inside their tool satchel.

Ollo is generous with labor and suspicious of explanations that sound too smooth. They trust Eiren's judgment because Eiren has earned it, yet feel insulted and frightened by Eiren's silence about the gate promise. In a workshop, Ollo is patient, wry, and delighted to teach; under pressure, they become blunt and fixated on consequences. When alone, they tend the herb cup with surprising gentleness.

Ollo learned boatwrighting from a parent who repaired fishing skiffs on the neighboring inlet, where a sound hull could mean the difference between a hard landing and a funeral. Years ago, during a storm surge, Ollo heard a damaged ferry groan before anyone else did and ordered its passengers ashore. The ferry broke loose minutes later. Since then, Ollo trusts the evidence of wood and water, and distrusts anyone who asks for faith without explanation. Ollo has worked beside Eiren Foamward for years, repairing small craft and sharing news carried between the inlets. They trust Eiren's judgment without hesitation, but Eiren's refusal to explain the gate promise has turned that trust into a painful, simmering anger. Ollo fears the promise may bind the neighboring inlet to a danger they have not been allowed to assess. They are still repairing boats, still caring for the herb garden, and still trying to find a way to ask Eiren one question that will not become a quarrel.
