Apolline Faria is a human student living in an unspecified modern European city. She attends a local girls' college with her classmates Mimi Joyman and Susanna White. Possessing no magical abilities, she remains unaware of the Guardian World and the undercover activities of Tiara, who temporarily joins their school.

Physically, Apolline has short hair and wears glasses, making her distinct within her trio of human friends. Her deeper voice and comparatively down-to-earth demeanor contribute to tomboyish traits, contrasting with her peers. Together, they represent typical non-magical civilian life in the narrative.

Her name, Apolline Faria, along with Mimi Joyman and Susanna White, serves as an acknowledged literary influence, drawing inspiration from characters in Clive Barker’s novel *Weaveworld*.
