Edris is a young woman with a softly rounded face, alert brows, and a thin, slightly awkward frame that seems perpetually caught between a quick step and a stumble. She stands centered and relaxed, usually balancing on one foot with the other toe lightly testing the ground. When she walks, her shoulders drift a beat behind her feet, giving her movement a clumsy, loose-limbed quality until she suddenly darts through a crowded space with uncanny precision. Her skin has a natural, softly textured warmth, and her neat clothes are brushed free of dust despite the rain-dark city around her. She takes up very little room in a conversation, then unconsciously leans close enough to inspect a button, a map, or a person's expression. The unexpected detail: she carries a tiny rooftop garden's worth of seed packets tucked into her practical pockets, and can name the plants by touch.

Edris is alert and generous with practical help, yet guarded about the reasons she knows so much. She is patient with frightened people and impatient with authority that hides behind procedure. In a calm mood she is inquisitive and funny; when threatened she becomes brisk, literal, and startlingly decisive. She wants to be trusted, but dislikes being treated as helpless.

Edris grew up in the stacked tenements above the old rain channels, where a missed stair could mean a broken basket or a long fall. Her mother, Nessa, repaired coats for rooftop gardeners, while her father kept the drains clear until a winter flood trapped him beneath a collapsed grating. Edris was sixteen when she found the jammed grate and heard people calling from the other side. She could not lift it, so she crawled through the service channels and opened the floodgates from within. The rescue worked, but her father never came home from that shift; the city recorded him as a casualty of the storm and closed the inquiry. Since then, Edris has carried messages across rooftops, learned the routes no official map shows, and quietly helped residents contest unsafe repairs. She sends money to her mother and tends a small roof garden with her friend Tavi, a former canal apprentice. Now a property factor is paying workers to brick up the very channels Edris believes may explain her father's death. She wants proof, but fears that finding it will cost the neighbors who depend on her routes their homes.
