Rosanna de Lacey presents as a striking human woman with pale elegant features, red eyes, a dusting of freckles, and a poised, theatrical smile. She favors a steampunk occult detective look, often wearing a purple top hat, tailored waistcoat, lilac or white blouse, thigh high boots, and impeccably fitted clothing that subtly evokes a dressmaker's precision. Her sword cane is always close at hand, and a silver talking flute is usually tucked somewhere surprising.

Charming, incisive, and quietly predatory, Rosanna performs kindness with the same precision that others use for surgery. She is eloquent in public, sly in private, and almost impossible to surprise. Beneath the cultivated polish is a mother who would defy heaven, hell, and her own curse for the people she loves.

Rosanna de Lacey was born into the ancient Von Wolfgang line under circumstances whispered about more often than they are explained. She came into the world touched by hunger and night, a half vampire with the terrible potential to become something far worse if she ever surrendered fully to the curse in her blood. From an early age she learned that beauty could be weaponized, charm could open doors, and fear could be steered like a carriage through a foggy street. She read objects the way other people read faces, made predictions that were too accurate to be comfortable, and moved with a blurring grace that made bullets seem slow. Yet every gift had a price. Her blood magic and curses demanded blood in return, and when deprived of it she grew pale, unstable, and dangerously feral. Her father, a famed Witcher and monster hunter, taught her how to survive the night and left her a legacy she still reveres, a magically reinforced sword cane she forged herself after his passing, and a silver talking flute that never quite stops commenting on her choices. Rosanna built a public life as a charming steampunk occult detective and dressmaker, a woman who could stitch lace by candlelight, expose a fraud with a smile, and quietly ruin a monster before supper. But her greatest test came when a savage pack of werewolves threatened her daughters, Olivia and Emmeline. Rosanna unleashed every dark power she possessed to protect them, and although they survived, she lost her soul to the blood curse that night. Since then, she has walked a knife edge between monster and mother, guided by pride, love, and the thin hope that she may still choose who she becomes.
