Steelhorn is a towering human woman with pale skin, a broad, powerful frame, and thick black hair usually braided with iron rings. Black geometric bone tattoos run from her knuckles up both arms and across her shoulders, marking the victories and graves of the Hotori tribe. She wears a battered horned helmet, dark furs, heavy leather, and a pair of longblades at her hips. Within a minute of meeting her, most people notice the sharp scent of pine smoke, oiled steel, and rendered fat that clings to her clothes. She constantly checks the iron rings in her braids with her fingertips, counting them under her breath before battle or difficult decisions.

Steelhorn is blunt, fearless, and intensely protective of ordinary people. She laughs loudly at bad plans, respects anyone who works with their hands, and has a surprisingly gentle patience with children, animals, and exhausted travelers. She dislikes ceremony but enjoys contests of strength, practical jokes, and the moment when a bully realizes the crowd is no longer afraid. Her loyalty is fierce but conditional, and once someone betrays the vulnerable, she treats reconciliation as a form of cowardice.

Steelhorn was born among the Hotori, a human tribe that measured adulthood in endurance, courage, and the willingness to stand between the helpless and the hungry. Her people lived beside black-pine forests and iron-rich hills, where every household knew how to hunt, forge, and fight. As a child, Steelhorn learned that strength was not merely the power to break a door. It was the power to hold one shut while others escaped. Her first black bone tattoo was earned when she carried three trapped children from a burning mine, returning again and again through smoke until the roof collapsed behind her. Years later, a predatory lord seized the Hotori winter stores and conscripted the tribe's smiths. Steelhorn answered by gathering hunters, charcoal burners, and disgruntled soldiers into a short, brutal rebellion. She shattered the lord's tax convoy, distributed its grain, and became a folk hero among the surrounding villages. The Hotori survived, but the victory scattered them, and Steelhorn now wanders in search of those who vanished during the uprising. She fights with two longblades because the Hotori taught that a warrior should always have one weapon for the enemy and one for the chain behind him. She is not needlessly cruel, but she trusts no throne, law, or promise that cannot survive the test of hunger.
