Iven has close-clipped dark hair that grows in coarse, even bristles, and a weather-browned face with a broad nose and deep creases beside his mouth. He plants his feet as if every surface might shift underfoot, then moves with a measured, economical stride. His watch coat is patched at the elbows with sailcloth and hangs a little too long in the sleeves. The polished brass whistle at his throat is conspicuously well cared for. Unexpectedly for a harbor sergeant, he keeps a tiny folded paper boat tucked in his breast pocket, refolding it whenever he waits.

Iven is patient with frightened people and impatient with posturing. He wants to be approachable, yet his sense of duty can make him rigid when a situation is ambiguous. In quiet moments he is dryly funny and attentive; under pressure he becomes brisk, procedural, and overly willing to shoulder every responsibility himself.

Iven grew up hauling nets along Greyhook's harbor wall, the son of a rope-maker whose work was often paid in favors instead of coin. He joined the Watch after a spring flood trapped his younger brother in a drainage tunnel. Iven led a rescue through a half-collapsed culvert and learned that knowing the town mattered more than looking imposing in uniform. Years later, during the Dockside Quarrel, he refused an order to drag an entire family from their home without proof of their involvement. The delay let a suspected arsonist escape, but it also prevented a frightened crowd from turning on the Watch. His captain called him insubordinate; the residents began trusting him. Now Greyhook's harbor crews and tunnel wardens both demand protection, while his short-handed patrols can barely cover either. He is close to his widowed sister, Ketta, who mends nets near the tide steps, and owes a debt of gratitude to tunnel cartographer Brann Ket, who helped him find his brother. His current captain, Geddik Voss, wants visible arrests to quiet the council. Iven is trying to keep the factions from forcing his hand.
