Alright, so I've only got three things. 

1. Rules please.

2. Reality Warping - I think what you mean to say here is her ability to cast Mental Illusions. Reality Warping is what Franklyn Richards does, where he can essentially create things, and they actually exist, whereas Jean here, would be just making a person think they are real.

For example, with the mansion thing. She can make a person [i]think[/i] that an old dingy house is a clean and beautiful mansion, while Franklyn can actually make that mansion a [i]reality[/i].

3. We need in the Bio how she'd get with the team, being that she was in New York in that school for a majority of the time. Being that Wolverine was part of the original Avengers lineup, that can be the avenue you can take, perhaps she talked to him about wanting to go elsewhere or if the professor feels like she needs to be there. In any case, that's how it could go down. We just need some kind of transition. :P
