Kora is a compact young woman with the dense, practical strength of someone raised hauling water, stone, and winter fuel. Her pregnancy is unmistakable, yet she moves with startling speed, keeping one hand lightly beneath her belly only when she thinks nobody is watching. Her skin is wind-darkened across the cheeks and nose, while the backs of her hands are rough with pale cracks from years of frost and salt. Thick black hair is braided into two ropes tied with red thread and tiny copper bells, though the bells never ring when she walks. Her eyes rarely settle on faces. Instead, she watches doorways, rafters, loose stones, and the hands of anyone near her. The contradictory impression is of a woman who looks physically burdened but carries herself like a person prepared to sprint across a roof.

Kora is generous with practical aid but suspicious of emotional intimacy. She can spend her last coin repairing a stranger's roof, then refuse to tell her closest ally where she is sleeping. Around children and frightened animals, she becomes patient and almost playful. Around scholars, nobles, and priests, she turns dry, exacting, and openly difficult. She dislikes being admired and secretly craves proof that someone would choose her without needing anything from her. Her greatest internal conflict is between her fierce desire to remain an ordinary person and her growing belief that she may have a duty to become something larger and less human.

Kora was born in the high mining settlement of Qhapaq Pass, where her family maintained the ancient stairways cut into the mountainside. She showed an unusual talent for hearing magical resonance in stone and became an apprentice to Vezh Ordo, a disgraced imperial geomancer. At nineteen, she joined an expedition into a sealed temple beneath a glacier. The expedition leader attempted to awaken the temple's buried weather engine, believing it would end the region's famines. Instead, the machine marked Kora as its living vessel. The mark took the form of a perpetual pregnancy, a sacred and terrible sign that the temple's intelligence had placed a fragment of itself within her. Kora destroyed the expedition's records and fled before the empire could claim her. The formative experience came when her younger brother Suri was crushed during the temple's collapse. Kora saved him by binding his soul into a copper bell, and she now carries that bell everywhere. Suri's voice sometimes answers from it, but he cannot always remember whether he is dead. Kora currently travels between mountain villages, sabotaging imperial leyline stations while searching for a way to separate the temple intelligence from her unborn child without killing either one.
