- This article is about the Grimmerie from the novel series. You may be looking for the book of the same name from the musical, or the companion book titled "Wicked: The Grimmerie".
The Grimmerie, known on Earth as the Lesser Key of Solomon, is a magical spell book (or grimoire) of magnificent power which Elphaba finds in the attic of Kiamo Ko and was later given to her by Sarima. Elphaba can only read parts of it, as the book originates from the other world (Earth). The book also created Yackle to be a guardian to the book and a witness to the tragic life of Elphaba.
The Wizard is in search of the Grimmerie, which had been hidden in Kiamo Ko and had entered into the ownership of the Tigelaar family. It was given to Elphaba Thropp by Sarima, who had no need for it as she couldn't read. It is further substantiated that the book comes from Earth rather than Oz in that those of pure Ozian ancestry can't read it whereas Elphaba-who is half-Ozian, half Earthling- can only read fragments.
The Wizard sought to bargain with Elphaba for the Grimmerie in exchange for Nor. This she did not allow, and it is revealed that, later, he asked Dorothy Gale to take the book if she could. Since it was too heavy, she was unable to do so.
In A Lion Among Men, it is revealed that Yackle is the guardian of the Grimmerie and was created from it. The Grimmerie had been secreted into the Clock of the Time Dragon, while a wayward page had been used by Emperor Shell to create dragons.
In Out of Oz, Glinda comes into posession of the Grimmerie when the Clock of the Time Dragon comes to Mockbeggar Hall. Glinda then--with the help of Elphaba's granddaughter Rain--uses the book to impede General Cherrystone's progress across Restwater Lake.
Eventually, as the battle progresses between Munchkinland and Loyal Oz, Mombey uses the books information on the training of Dragons to attack the Emerald City, successfully ending the war. After failing to bring Liir back from his Animal form, Mombey attempts to use the Grimmerie to "call the lost forward." In doing so, she reveals Ozma Tippetarius as well as Rain's green skin.
At the end of the novel, Rain takes the Grimmerie and--using the broom--flies out past the Thousand Year Grasslands and an expanse of desert to the ocean. She then continues to fly over the sea, vowing to drop the book into its depths.
