A petite young woman stands as if the rain-dark railing beside her might suddenly become a path. Her shoulders tuck inward, but her weight stays poised over the balls of her feet, ready to spring. Damp curls cling in loose commas to her forehead, and her guarded half-smile arrives a beat before her trust does. Her clothes are neat rather than fine, their rain-beaded surfaces catching lamplight against the blurred brick roofs, drain channels, narrow stairs, and rooftop greenery behind her. She leaves the impression of a person who has already noticed three exits and is deciding which one you have missed.

Eshra is alert and quick-witted, but not naturally bold; she will take a dangerous route for someone else and then insist it was the sensible option. She enjoys gossip when it helps her understand the neighborhood, yet guards her own feelings with clipped jokes. When relaxed she is generous with directions and small favors. When frightened, she gets brisk, counts exits, and tries to turn everyone into a plan.

Eshra grew up in the steep old-city quarter of narrow stairs and rooftop gardens, where her mother, Nima, kept a tiny kitchen garden above a crowded tenement. As a child, Eshra learned which drain channels carried rainwater and which carried a neighbor's washing, and she began carrying messages across roofs for people who could not afford a hired runner. During a cloudburst five years ago, a rooftop stair collapsed beneath her younger cousin, Tavi. Eshra got Tavi out, but a locked courtyard gate kept her from reaching an injured neighbor in time. Since then she has mapped every passage and exit she can find, and she cannot pass a jammed door without testing it. Now the city plans to seal several roof walks during repairs, cutting off the quickest route between the quarter's homes. Eshra is quietly gathering residents to oppose the closures while trying not to turn their protest into another emergency.
