John Stewart is an interesting Lantern because he’s more cerebral than many of the other earth Lanterns (especially Guy Gardner)who fight their way through problems. John doesn’t. He holds a fair to bring unity and gives power rings to allow the residents to police themselves. He allows residents to try to convert other lifeforms to their religion because he supports freedom of religion. He’s more of a politician than a policeman.

He assembles a ragtag team of X-Men, mostly made of prisoners lying around the Mansion. He, Jubilee, the White Queen and Sabretooth set out on a mission to protect the next generation of mutants!
