Nate Grey was known for his powers. Other than certain members of his family (and certain cosmic forces), he was the most powerful telepath on the planet. Even including them, he was possibly the most powerful telekinetic in the world. Between the two, it was often thought that he could do most anything that came to mind. And, in a lot of cases, it was true. But there were things that even Nate struggled with, powers that even he couldn't control, despite his years of training and his time spent in other worlds trying to learn. One of these was his precognition.
It wasn't a readily known aspect of his mutation, primarily because it could be so unpredictable and indecipherable. He received visions of the future on occasion; not often, and almost always in his dreams, but they were things that never failed to come to fruition. He'd long ago given up on trying to force them, simply taking them as they came.
Only a few days before Christmas, they came again.
A dream-vision, not of this world, but of his home dimension. Apocalypse's world. The slave pens, the rebels, Apocalypse himself. And Nate there, with a group of heroes, finishing the mission that he'd been created for. Taking down Apocalypse, and ending his horrific world rule. Nate could feel it in his bones long after he woke up. This was meant to happen. This needed to happen. He had to take those people, the ones from this world, the ones in his dream, and bring them back to his. With that group, he would be able to stop Apocalypse, end he and his son and all of their followers.
He went to Scott immediately, telling him of it. After this was done, after his world was saved, he would come back and die for this one. But this had to be first. And he had to have those people with him. Lorna, Prince, Michelle, Luka, Morgan. An odd group, to be sure, and mostly overlooked when it came to their powers here. But they were the ones. They had to go with him. And it had to be before the new year.
