A young woman with a soft, alert face and an awkwardly balanced stance, as if she has paused halfway through deciding where to put her feet. Her jaw is slightly broad, and her two upper front teeth overlap just enough to show when she smiles; she presses her lips together when trying not to laugh. She walks with quick, careful steps, turning her shoulders sideways through narrow spaces and setting each foot as quietly as a cat on a tiled roof. There is no injury or theatrical toughness to her look. Instead, the unexpected detail is a tiny, meticulously tended rooftop garden: a living sprig of mint tucked into the seam of her coat, its leaves brushed clean of dust. She leaves the impression of someone who notices every exit, then asks whether you have eaten.

Ashti is observant and quick to help, yet guarded about her own needs. With strangers she can seem awkwardly formal, checking facts before she offers comfort; with a frightened person she becomes gentle and practical, finding them a task and a safe place to sit. When challenged about the fire or her work, she turns sharp and argumentative. In a rare carefree mood, she laughs with her whole face and makes jokes that are much bolder than her usual manner.

Ashti grew up in the steep old quarter of Tbilen, where stairs double back, rainwater cuts channels through brick, and rooftops make a second, unofficial street. Her mother, Nino, repaired clothes for the tenants of the Sunstep Court, a name left over from a grand sunlit courtyard that is now mostly shaded by taller buildings. Ashti learned the roof routes carrying parcels for shopkeepers, then took paid work finding people who had vanished into the crowded quarter. At seventeen, she was hired to guide a group of residents out during a fire in a tenement above the old drain. She found a route for the children but froze when smoke and shouting turned the familiar roofline into a maze. Her friend Dato got the last two residents down and suffered a lasting injury to his lungs. Ashti has never forgotten the sound of him coughing on the stairs. It changed her from a nimble, heedless runner into someone who checks every route twice and keeps emergency water at three rooftops. Now she earns modest fees locating missing people and quietly helps tenants resist an eviction scheme backed by a wealthy property-holder. Her mother thinks she should leave the dangerous work; Dato says she has mistaken guilt for responsibility. She is trying to prove that careful work can still be brave.
