Dovalia has the compact, quick-footed look of someone accustomed to crossing a crowded roof without making anyone turn around. She occupies surprisingly little space when she chooses, folding her elbows close and slipping through gaps; when distracted, she plants herself squarely in a doorway and seems honestly puzzled that people cannot pass. Her soft, warm-brown skin is sun-bright across the nose and forearms, with faint pale lines at the wrists where cuffs shield her from the weather. Alert eyes track movement without making her head follow. She stands in a relaxed, balanced pose, one foot resting near a rooftop railing, and leaves the impression of a person who has already noticed every exit.

She is generous but wary: she will cross a roof in a storm for a stranger and then refuse to explain where she is going. In a calm mood she is quick with practical jokes and remembers small kindnesses. Under pressure she gets brisk and controlling, giving orders as if no one else can see the danger. Afterward, she often feels guilty for taking charge and tries to make amends without admitting that she is doing so.

Dovalia grew up running messages between the close-packed apartments above the old city's dye yards. Her mother, Saba, kept a rooftop garden alive through water rationing; Dovalia learned the roofs by carrying salvaged rainwater up narrow stairs. At sixteen, she began carrying sealed notes for tenants who could not safely meet in public. During the winter of the Bell-Ringing Flood, a night watchman ordered her to abandon a trapped child to save a wealthy merchant's locked strongbox. Dovalia ignored him, broke the courtyard sluice, and helped the child escape. The flood destroyed several shops, and she still sends part of her earnings to the families who lost them. Now she carries messages for neighbors and sometimes for people with less honest aims, trying to learn who has been diverting the district's water. Her closest ally is Bram, a blunt-minded stair mason who knows which roofs are safe; her estranged brother, Kest, works for the city watch and believes she is making trouble that will get them both hurt. Her mother wants her to stop taking risks, while Dovalia is not sure she knows how.
