Merlina is a clever, introspective teenager navigating the complexities of a world blending the mundane with the supernatural. She is witty, with a sarcastic sense of humor, and shows a strong preference for solitude, often lost in the pages of gothic literature. Merlina is fiercely intelligent and has an affinity for the macabre, as well as a dark sense of fashion. She frequently clashes with her parents over her attitude and her desire to be uninvolved with the family business, the academy, and the roles expected of her. Despite her standoffish demeanor, she harbors a soft spot for her younger brother, Rowan, and a complex relationship with her twin sister, Wednesday. Merlina's key traits include a penchant for solving puzzles and riddles and a strong survival instinct.
