Ulla looks as if she has spent years learning how not to be the most noticeable person in a room, then forgotten that the effort leaves its own impression. Her skin is weather-browned and lightly freckled; her dark hair is cut at her jaw and usually pinned back with a length of cord. She smells distinctly of crushed mint, bow wax, and rain-damp wool, a scent she notices only when someone else comments on it. Her eyes rarely settle on faces: they travel to hands, doorways, windows, and the spaces between people. She moves with a hunter's economical certainty, placing each foot as if the floor might give evidence. Unexpectedly, she carries a tiny clay bird whistle and uses it to call ordinary songbirds, not just to signal allies.

Ulla is patient with frightened people but impatient with anyone who mistakes confidence for competence. She jokes when a room is tense, then turns relentlessly practical when danger becomes real. She wants to believe that most beings can be reasoned with, yet she distrusts anyone who asks her to act before she has seen the ground herself. Around children and injured animals, her guarded manner gives way to surprising warmth; after a betrayal, she becomes polite only in the sense that she wastes no words.

Ulla grew up in a logging settlement where people learned to read snapped twigs and mud before they learned to read a map. Her mother, Heg, taught her to track lost children and injured animals; her father, Gant, taught her how to repair a bow and how to leave a place before a fight became unavoidable. At nineteen, Ulla joined a licensed expedition into a forbidden valley, hoping to prove that its supposed man-eating beast was only a story. She found instead a wounded creature guarding its young. When the expedition leader ordered her to shoot, Ulla turned her bow on the leader's lantern and gave the animals time to escape. The fire that followed killed two companions and ended her place on the expedition. That night changed her from a tracker who pursued every quarry into one who asks what a target is protecting. She later trained with a quiet Nen practitioner, learning to focus attention and intent into a disciplined mark. Now she works as an independent Hunter, searching for a missing cartographer and trying to discover who has been buying maps to the valley. Her mother still sends her practical letters; her former expedition partner, Tekk, sends warnings that sound like threats and may be either.
