Bera looks like a squat, soot-darkened anvil that has learned to walk: compact and broad, with skin stippled by coal dust and fine metal flecks that never quite wash away. Her heavy brows shade amber-brown eyes, and her iron-gray hair is braided into a short tail secured with a bent copper nail. She moves with a deliberate side-to-side sway, favoring her left heel as if every floor were a slope under survey. A small brass plumb bob hangs at her throat, its tip polished bright by years of her thumb rubbing it. The unexpected detail is a neat row of tiny painted flowers along the inside edge of her work apron, refreshed whenever she has a quiet afternoon.

Bera is candid and stubborn, but not as hard-hearted as she presents herself. She distrusts grand promises yet is unexpectedly generous with people who show up consistently. At work she is exacting and brisk; with frightened travelers she becomes patient, offering simple tasks to restore their sense of control. When ashamed, she turns practical and argumentative rather than apologizing.

Bera inherited her stubbornness and her first hammer from her aunt, who taught her to listen for flaws in a bar of iron by tapping it against a stone. In her youth she worked on the Ninth Survey Road, forging spikes, hinges, and bridge fittings for a team that mapped a pass through the hills. During a disastrous thaw, a temporary bridge gave way beneath a supply cart. Bera could save either the cart's trapped driver or the stamped survey case containing the route records. She chose the driver, a young assistant named Pask, and the records vanished downriver. The choice saved a life and cost her the contract; she still considers both outcomes hers to carry. Years later, she opened The Eighth Survey Forge in a former road station, where travelers can buy reliable tools and hear which routes are safe. Her former apprentice, Kett, now repairs railings for the town and accuses Bera of keeping work that should be shared. Meanwhile, the local road committee is pressuring her to sell the forge's courtyard for a new toll office. Bera has found old survey marks beneath its stones and suspects the proposed road would cut through an unstable cavern.
