Charles Xavier (X-Men) is winding down the Spring Term at his School for the Gifted, when his newest mutant--Claire Bennet (Heroes)--reveals a prior letter from Hogwarts School inviting her to enroll. In conversation with emissaries from Hogwarts, Xavier becomes intrigued by the idea of a "magic education" that could expand powers, while Hogwarts in turn is interested in Xavier's ability to develop inherent biological powers, given that magic appears to be inherited (even if from distant ancestors). Xavier and Claire are given three young Muggle-born pupils for a summer program: Hogwarts's brightest young student, Hermione Granger (Harry Potter); a very young but terribly precocious talent, Matilda Wormwood (Matilda); and a teenage genius whose prior school failed her magical training, Elphaba (Wicked). The result is a high-fantasy take on the X-Men, with some battles but more deliberate exploration of the capabilities and limitations of "magic" and other superhuman power in this world--and the ethical problems posed by same.
