Part of the Greek Pantheon, Hecate is a deity of witchcraft and magic. Her dominion is over the starry skies and the stormy seas. She is also a Chthonic deity, meaning her dominion spreads over the world of the dead.

Despite her formidable reputation, Hecate was the deity with whom Alexandra shared a unique bond. Hecate demanded that Alexandra view herself "with an objective eye", a constant reminder for Alexandra to stay in touch with her true motivations.
