Oh my goodness I totally forgot Conjuration!
I'm assuming it exists in one form or another because looking at characters abilities I've noticed some people can summon animals or creatures to assist them. As far as theories go could one use magic to move from one point to another instantaneously? or could it concievably be used to bring beings from other planes to the plane of the wielder? (I'm thinking something along the lines of calling a Demon from Hell to the surface or something like that)

This one is mostly academic to be honest because I think summoning up a demon or angel from another plane is just asking for trouble lol
