Cassandra means "oracle". In Greek mythology, Cassandra means "she who entangles men" and she was the daughter of King Priam and Queen Hecuba. Apollo, god of archery and poetry, as well as oracles, fell in love for her beauty and gave her the gift of prophecy. However, when she did not return his love, Apollo placed a curse on her so that no one would ever believe her predictions and her visions would only be of tragic events yet to come.
Behind the scenes
- Vablatsky’s death date was given on a Famous Wizard Card in the video game adaptation of Harry Potter and the Philosopher's Stone, which takes place in 1991-1992. Vablatsky’s death date is given as 6 years later. This could be a reference to the Seer's skills, given that she could have predicted her own death.
- She was likely named after Madame Helena Blavatsky, a 19th-century psychic and founder of the Theosophy movement and early proponent of New Age philosophy, who was declared a fraud in 1885 by the Society of Psychical Research. She was known for fusing ideas of modern science with esoteric tenets of Eastern spirituality.
