Wicked explores the backstories of Glinda and Elphaba before and after The Wizard of Oz

"Wicked" serves as both a prequel and a sequel to "The Wizard of Oz." It explores the backstories of Glinda and Elphaba, the Wicked Witch, before Dorothy's arrival in Oz. The story reinterprets familiar characters and events. The narrative begins with Elphaba's childhood and her experiences at Shiz University. It highlights her friendship with Glinda and her growing awareness of corruption in Oz, leading to her disillusionment with the Wizard's regime. While "Wicked" provides context for events in "The Wizard of Oz," it also presents an alternative viewpoint on morality and power. This makes it a reimagining rather than a straightforward prequel or sequel.
