Varka moves with a measured, slightly favoring gait, as though every floor might conceal a loose stone. Her compact frame is usually dusted with pale lime and gritty mortar. She keeps her dark hair combed into a severe knot, but short curls escape around her ears by midday. Her coat hangs heavy with tools, and she studies doorways and arches with the same unsparing attention other people give faces. Unexpectedly for a hard-nosed engineer, she keeps a tiny paper kite tucked inside her collar, its folds carefully repaired.

Varka is decisive when stone, water, and deadlines are involved, yet hesitant when a conversation touches her daughter. She can be blunt enough to wound a friend, then quietly spend the night repairing that friend's roof. In a crisis her attention narrows into calm, precise instructions; away from danger she can become guarded, dryly funny, and unexpectedly sentimental.

Varka once designed floodgates and bridge spans for Drauvana, where a single misplaced support could drown a district. During the spring surge at the old Sedge Crossing, she trusted a superior's hurried measurements over her own uneasy calculations. The bridge failed under a cart train. Varka survived, but the disaster killed several workers and ended her career in the city works office. That failure changed her: she no longer signs off on a structure she has not walked herself, and she will argue with anyone who calls a dangerous shortcut acceptable. She now leads the rebuilding of Drauvana's aqueducts, hiring day laborers and negotiating for stone from the stubborn quarry town of Vost. Her daughter, Lida, has become a rallying figure for people demanding clean water. Varka is proud of her courage, yet worries that Drauvana's crowds have turned Lida into a banner and stopped noticing the frightened young woman beneath it. Varka and Lida love one another, but their arguments over public speeches and private safety have grown sharp. Meanwhile, a section of the upper aqueduct keeps losing pressure at night, and Varka suspects someone is diverting water or concealing a structural defect.
