Alright. After a talk with Xeloras, we've decided that abjuration doesn't involve the manipulation of mass and inertia, but instead the application of magical force and motion; e.g., featherfall is a cone of force directed downward to slow your fall, push is a thrust of magical force, and so on. Doesn't change much about this character, save the details of her magic and perhaps the implications of her manipulating mass. This character is still accepted, but try to take into account this change.
