Aurora Sinistra

Aurora Sinistra is the Astronomy Professor and Head of Slytherin House at Hogwarts.

History
Aurora has spent her whole life looking up at the stars. Although she dreamed of becoming an astronaut as a young child, she knew that her nudist lifestyle would not permit her to be a part of a Muggle space program. Thus, she accepted the Astronomy Professorship at Hogwarts as soon as she graduated, where she has remained ever since. In September of 1992 she was hypnotized by Emily Wagner and later drugged with an 'Amnesia Suppository' by the Headmistess after a playful plot to hypnotize her went awry. Following this, she developed an anesthesia fetish and started to regularly drug her 'friend-with-benefits' Charity Burbage, most notably in August of 1993 when she took over refreshing Isabella Patterson's Prefect training for her.

Personality
Aurora is rather seductive, even compared to her fellow Professors. She likes to start each Astronomy class off by having her students look into spirals embedded into her telescopes, which she claims to do in order to get them to associate the subject with hypnotic bliss. Commonly ranked as one of the prettiest Professors in the school by informal surveys, she has no trouble seducing her students, taking at least one to bed nearly every night. Despite her distance from the Slytherin Common Room, she is held in high regard by her students, whom she is most fond of.

Relationship with Charity Burbage
Aurora is 'friends-with-benefits' with the Muggle Studies Professor, Charity Burbage, whom she frequently hypnotizes and drugs, and vice-versa. Despite being together since the mid-1980s, they have no romantic interest in each other.
