The Ultimate Book of Spells (2001)

Inspired by the popular Harry Potter book and movie series, the show presents a trio of "wizards-in-training" at an enchanted private school run by Miss Crystalgazer. Cassy is a junior witch, Gus is a half-elf/half-human junior wizard, and Verne is a promising "mortie", i.e. a non-magical human. With the guidance of the talking Ultimate Book of Spells (aka UBOS), the three have to battle the evil wizard Zarlak, who's trying to steal all of the world's spells.
