Ulla is caught in a constant half-turn, as if even standing still requires her to keep track of every exit. Her face is broad-cheeked and sun-browned, with a small notch in one eyebrow from an old, unremarkable training accident. Her dark hair is cut to jaw length and usually pinned back with a bent brass awl. She moves with the compact, spring-loaded balance of someone who has spent years walking crowded docks; her boots scarcely scuff the ground. When she pivots, a teal sash snaps around her like a brushstroke, followed by a scatter of dust. Unexpectedly, a tiny clay swallow hangs from her sword belt, its beak rubbed smooth from her thumb.

Ulla is quick to offer help and slow to accept it. In a crisis she becomes precise, economical, and almost startlingly calm; in a quiet room she is restless and easily embarrassed by affection. She jokes with workers and children, but turns formal around officers. She wants to be trusted as a capable fighter, yet distrusts anyone who treats obedience as the same thing as courage.

Ulla grew up carrying parcels between the fish piers and the hill markets of Bramble Quay, a riverside town built after its residents drained a stubborn marsh. Her mother, Sada, mended nets; her father, Farrokh, ferried passengers and taught Ulla to read currents by watching floating scraps. At seventeen, she joined a caravan guard crew for steady pay. During a night ambush on the flooded causeway, their sergeant ordered the guards to hold formation while a cart carrying trapped families tipped toward the water. Ulla broke ranks, turned aside a blade meant for a child, and helped pull six people free. The sergeant called it insubordination; the survivors called it the reason they lived. She left the crew soon afterward, carrying the cracked clay swallow one rescued child pressed into her hand. Now she works as a hired escort and occasional dockside mediator. She sends money home, but her father has begun losing his sight and refuses to leave the river. Her former sergeant, Drenek, still insists she owes him an apology, while one of the rescued children, now a young courier named Pacha, seeks her out whenever trouble finds the roads.
