Master Zacharius's eighteen-year-old daughter. Growing up without a mother, she spent her youth in the derelict workshop, looking after her old master's health and clinging to divine values. With her pure and self-sacrificing character, she is the main center of Aubert's great loyalty. Within the novel's dark progression, she is represented as the luminous face of Catholic faith, purity, and love. She attempts to pull her father out of his spiritual hell by remaining pathologically loyal to him no matter what, but ultimately faces becoming the ruthless and tragedy-filled victim of demonic demands.
Trapped in the most beautiful room of their house in Geneva, she grew up in a spiritually immaculate sanctuary. Having solidified her faith in the presence of naive depictions of Mary in an atmosphere not yet fully submissive to the austerity of Calvinism, she reached a maturity that allowed her to feel the weight of her father's physical and mental collapse on her shoulders, despite her young age.
