So one of the PCs decided that they have encountered a powerful force using character, a NightBrother specifically, and that this NPC has the ability to send them to another planet instantaneously using the force. Obviously, this being a fantasy realm, and the NightBrothers largely unexplored, I can't say that it is absolutely impossible, but on the other hand I have no precedent for anything like this and not sure how to handle it.
Thoughts?
