Mina has a compact, purposeful presence, moving with the economical turns of someone who has crossed a crowded ward carrying hot water in both hands. Her dark hair is combed back and pinned so tightly that not a strand strays, a degree of grooming that persists even after a long shift. She wears a practical coat with broad pockets and a small ink stain on the left cuff. The stain is sharp-edged and unmistakable, and she refuses to change the cuff until the current inventory is settled. A worn brass diagnostic lens hangs at her throat, its cord polished smooth where her thumb worries it. People tend to remember her steady gaze and the impression that she has already noticed what they are trying not to say.

Mina is scrupulously patient with frightened people and impatient with anyone who uses procedure to avoid responsibility. She is warm in the practical ways that matter, bringing water or staying through a difficult night, but she guards her private feelings behind careful questions. In a crisis she becomes brisk and decisive; afterward, she can spend hours doubting whether she acted too soon or too late.

Mina grew up in Common Measure, where her mother repaired pumps and her father copied ration notices for neighbors who could not read. During the winter fever, she was a young ward assistant when a shipment of medicine arrived with fewer doses than its manifest claimed. The clinic's overseer delayed treatment while officials argued over whose tally was authoritative. Mina broke the seal on a reserved case and treated the sick children first. Most survived; she was dismissed from her first post for falsifying the issue record. The event taught her both that rules can protect people and that a tidy record can be used to abandon them. Years of apprenticeship and hard-won trust eventually made her chief physician, responsible for the clinic wards and their inventory. She now works closely with Sesh, a quick-witted apprentice who wants to expose the Combine's accounting practices, and keeps wary contact with Bruna, a former supply clerk who once covered for Mina and still knows where old records are buried. Her present problem is a discrepancy between medicine actually dispensed and the Combine's official inventory. If it is resolved carelessly, patients may be charged for treatment they already received.
