Geth looks like a man weathered into the shape of his work. Rain has stippled his brown skin with pale flecks across his forearms, while years of hauling rope have left his palms ridged and darkened. He moves with a slow, grounded economy, then turns startlingly fast when something shifts at the edge of his attention. His most unexpected detail is a tiny brass thimble tied to his sword belt, polished bright from constant handling; he uses it to mend torn gloves and insists it belonged to his first teacher.

Geth is protective but not tender in public, and he respects a hard truth more than a comforting lie. Around frightened people, he becomes patient and practical; around show-offs, he grows blunt and tests their claims. When relaxed, he is unexpectedly fond of gossip and bad kitchen jokes. When ashamed, he overworks and calls it duty.

Geth grew up hauling salvage from the flood channels beneath the river-port of Sesh. He learned to read current, mud, and the panic in a person's shoulders before he learned formal sword drills. At twenty-six, a flash flood trapped his crew in a culvert. His captain, Hessa, ordered him to cut a rescue line so the rest could climb out; Geth hesitated because his younger brother was still below. By the time he cut it, the current had taken the boy. The event ended his work as a salvage diver and made him a watch sergeant, determined never again to let a difficult choice become an excuse for delay. He now guards the old causeways and quietly sends money to his widowed sister, Thabisa. His former captain, Hessa, still trusts his judgment but believes he has turned caution into a private punishment. Lately, someone has been prying open sealed floodgates at night, and Geth suspects the sabotage is connected to the same smuggling route that once paid his crew.
