Kassy's brown hair flows in a thick, loosely tied fall down her back, usually escaping its cord in wisps that cling to her temples in the heat of the forge. Her pale skin is freckled with tiny soot specks that never quite scrub away. She moves with a smith's efficient economy: hips turned to pass through narrow spaces, shoulders balanced as if carrying a tool basket even when her hands are empty. Her eyes sweep a room's exits, hands, and unattended objects before settling on anyone's face. The unexpected detail is that she keeps a tiny paper windmill tucked into her jacket cuff, replacing it whenever the old one tears.

Kassy is practical enough to count every nail and compassionate enough to give away the nails someone needs to mend a door. In a crisis she becomes direct and decisive; in quiet company she is teasing and surprisingly playful. She dislikes being treated as helpless, yet often hides her own needs behind errands and favors. She values proof, but her instinct to protect people can outrun her caution.

Kassy Askel grew up in the back rooms of a working smithy, where she learned numbers by tallying nails and learned metal by listening to it ring. She became the clerk for a busy neighborhood forge, handling orders, customers, and the books while raising her young son, Tavi. Years ago, a furnace accident trapped her father behind a buckled door. Kassy was the only one small and strong enough to crawl through the coal hatch and drag him clear; the burns on his arms healed, but he never returned to the forge. That day taught her that a ledger can wait and a person cannot. Now she runs the counter for her employer, Sennik, and quietly takes in repair work from families who cannot pay full price. A supplier's recent short deliveries have left the forge unable to meet a contract, and Kassy suspects someone is diverting the metal. She is trying to protect the shop without letting her son see how close its debts have come to swallowing their home.
