Diane

Pre-show announcement
This is how Diane was first introduced:

Will escaping her family life and heading off to another year at the Academy be exactly what she needs?

Additional information
Diane runs to be president of the student body. Her only known rival in this race is Heath.

Spellbook
Diane's spell book is a plain notebook; it is indistinct and brand new. In, Nika adds that it is boring and doesn't look magic at all; it looks like the most corporate of diaries instead.
