Dazsa Dombi has dark teal scales with a fine, pebbled texture that catches light like wet river stone. A blunt ridge runs from her brow to the back of her skull, and her jaw has the heavy, squared look of a built-in helmet. She moves with a train guard's practiced economy: feet planted for sudden jolts, head turning before her shoulders, gaze checking hands and exits rather than faces. When the carriage lurches, she barely sways. Unexpectedly, she keeps a folded paper menagerie in her breast pocket and makes tiny cranes from confiscated tickets during quiet shifts.

She is disciplined enough to memorize every carriage's emergency exits, yet compassionate enough to break protocol for a terrified stowaway. In routine situations she is dryly humorous and almost domestic in her care for passengers. Under pressure she becomes brisk, directive, and difficult to interrupt. She distrusts easy promises but keeps her own, sometimes at considerable cost.

Dazsa grew up in a family of canal-haulers, learning to read weather in the pressure of air against her horns and to sleep through machinery's clatter. She joined the rail service after her younger brother, Gvantsa, disappeared during a night run through the mountain cut. The company called it an accident and ordered the line reopened. Dazsa refused, braced a signal lever with her own body, and held a crowded train at the last safe platform until rescuers found survivors in a collapsed tunnel. The experience made her both fiercely protective and suspicious of official explanations. She now guards the passenger trains that cross the same route, while quietly searching for proof that her brother's disappearance was engineered. Her former instructor, Tseren, still believes she can save the service from its own management; a station medic, Kiyomi, thinks Dazsa is letting the search consume her.
