- A sorceress will arrive in Oz by cyclone and become the Witch of the West, unseating the greatest evil that the realm has ever seen. (unfulfilled)
The Sisterhood of Witches tell Zelena that they think she is the sorceress destined to join them and rule the western region of Oz. However, when Dorothy Gale arrives, Zelena reads through the Book of Records and discovers the other prophecy. She assumes that she, herself, is the greatest evil that will be overthrown by Dorothy, who will become the new Witch of the West. However, this prophecy does not come to pass.
