A young woman with rounded ears, expressive brows, and a perpetually bewildered look, as if the city has just changed one of its rules without telling her. She stands slightly off-balance, one knee relaxed and one shoulder drawn in, but seems to occupy more space than her thin frame suggests because she keeps turning to check every rooftop, drain, and doorway around her. Her skin looks softly textured and carefully protected from the weather. Her hair is pinned back in practical, slightly uneven coils, with rain-frizzed wisps escaping around her temples. Her bright eyes dart toward small movements. The first thing people tend to notice is the little breath she takes before speaking, a caught intake that makes it seem she has just remembered something urgent.

Ratik is observant enough to notice a loose roof tile across a busy street, yet can lose her place mid-sentence when three people ask her questions at once. She is wary of authority but conscientious about her municipal work; she wants to expose wrongdoing without abandoning the residents who rely on the same office. With strangers she is guarded and awkward, with children she is patient and inventive, and under immediate pressure her bewilderment hardens into focused urgency.

Ratik grew up above the old drainworks, where her mother, Nima, repaired roof cisterns and taught her to read the city's hidden water routes. As a child, Ratik drew maps on flour sacks and delivered messages between rooftop gardens. At seventeen, a cloudburst flooded the lower lanes. She found a blocked sluice but froze when a panicked crowd pressed toward it. Her younger brother had to pull her aside and clear the grate; a neighbor was swept away. Ratik has never forgotten the moment when knowing the route was not the same as acting. She now works as a runner and unofficial surveyor for the Canal Office, mapping unsafe stairs, drains, and roof access. Her supervisor, Varo, appreciates her accuracy but wants her to stop documenting repairs the office has not funded. Ratik also keeps in contact with her brother, who now leads a tenants' mutual-aid crew in the crowded district called the Draincut, named for the channel dug to make the neighborhood habitable. Her current problem is a set of fresh chalk marks showing that someone has been quietly redirecting floodwater toward poorer streets.
