Lilith is the opposite of Eda. She is loyal and devoted to the laws of magic, and at the time was considered to be one of the most honorable and respected witches on the Boiling Isles. As leader of the Emperor's Coven, it was her duty to enforce the Emperor's laws as well train new generations of powerful witches. Among those witches was Amity Blight, who she considered one of her top students.
