He had the power of pyrokenisis, I granted him that. Martin enhanced his power significantly, since Mithias has a heart he has some form of heat signiture. You said yourself vampires gave off radiation, radiation can cause heat, radiation also causes explosions. His power wasn't magical, it was psychic. It is also far from summoning demons. Perhaps the wings could have been metaphorical, I'd imagine Mithias was heated abnormally from the fire, so therefore when the heat hit the cold it could have the same effect as steam to a certain degree. Which would make sense that it eventually stopped. No offense, but it has to be said. You were getting quite out of control with Jack and Terebitha, completely controlling the RP virtually, making Jack untouchable is the very definition of godmode. I allowed him to do this for the sole fact that I can't see something of that magnitude happening often or ever again for that matter.
