TRANCE

When Legion created a dystopian pocket reality known as Age of X, all mutants were confined to Fortress X, from which they defended themselves against waves of attacks from human forces. However, as with all other mutants, this was the real Trance, as she and all the residents of Utopia had become the victim of the reality warp from Legion. Eventually, this revised reality was undone and Trance and all of the X-Men returned to the real world in their original forms. This pocket reality was later given a designation as Earth-11326, so it is possible this variation of this Trance exists in the multiverse.
