Now outed as a mutant, Xavier makes speeches to the public about mutant tolerance. He also founds the X-Corporation, or X-Corp (not to be confused with the X-Corps), with offices all over the world. The purpose of the X-Corp is to watch over mutant rights and help mutants in need. As a result of being out, the school no longer hides the fact that it is a school for mutants and it opens its doors for more mutant (and even human) students to come in. A student named Quentin Quire and members of his gang start a riot at the Xavier Institute during an open house at the school. As a result, Quire and two other students are killed. Uncertain about his dream's validity, Xavier announces that he will step down as headmaster and be succeeded by Jean Grey. Afterwards, Xorn reveals himself to be Magneto, having apparently not died in the Sentinel raid on Genosha. Magneto undoes the restoration of Xavier's ability to walk, kidnaps him, and destroys the X-Mansion (killing several of the students). Then Xorn/Magneto assaults New York, where Cyclops, Fantomex and a few students confront him. After the rest of the X-Men arrive, Xorn/Magneto kills Jean Grey with an electromagnetically induced stroke, and Wolverine decapitates him. With Jean dead, Xavier leaves the school to Cyclops and Emma Frost, to bury Xorn/Magneto in Genosha. In a retcon of Grant Morrison's storyline, there Xavier meets the "real" Magneto, who mysteriously survived Cassandra Nova's assault. The two resolve their differences and attempt to restore their friendship, leading a team of mutants, the Genoshan Excalibur, to rebuild and restore order to the destroyed island nation.
