She is a young girl who becomes an apprentice witch under the witch Qifrey after her initial accidental use of forbidden magic turned her mother to crystal. She hopes to search the Tower of Books for the book containing the magic, in order to reverse its effects on her mother.

She is quite a dork for magic, with a child-like (even for her age) widen eyed look whenever she sees things that are common for every other witch. The very magic that inspired her was simple magic made by Qifrey's watcher that caused glowstone path to light up.
