Glossaryck lets Star pick any page in the book to learn some new magic. Star chooses a mysterious chapter, but Glossaryck tells her it is very dark magic and that he will only let her get a short peek at the page. However, Glossaryck is summoned to the Bureau of Magic; he tells Star not to turn to that page, and his consciousness is dragged away into another dimension. While Glossaryck must deal with a not-so-helpful receptionist and has a difficult time getting to the top floor because the magic system is "on the fritz", Star is tempted to turn the page, and enlists Marco to help do it.
After having skirmished with a number of dangerous monsters, Star Butterfly arrives on Earth to live with the Diaz family. However, rather than living a normal life, Star continues on having to battle villains both throughout the universe and in their high school, although if only to protect her extremely powerful wand, an object which she is still confused with.
