Sister Flint

Sister Flint was a Red Sister and mistress of Grey Class at Sweet Mercy. She had Gerant traits and was very tall, towering above others, her height seemingly gained by stretching a regular woman far beyond her design, leaving her dangerously thin. Sister Flint was Thread-Linked to the Noi-Guin assassin's knife that Nona found in her bed, along with Sister Wheel and Kettle. She must also have been linked to Yisht's possessions, for she was drawn on her secret return to the convent. Hessa found her corpse before Yisht killed her as well. Sister Heart later took over her role as Grey Class mistress.
