Cardinal Fire

Cardinal Fire is what Eric Crowe had used to destroy a demon that he had been hunting with Kate Connor in the catacombs under Rome. This fire was given to him by Wilson Endicott this weapon to use as a last resort and in the process broke a lot of Forza's rules. When Eric Crowe was little, Forza locked a demon up inside of him that had remained dormant until he used the Cardinal Fire, which awakened the demon. The demon was shielded so it wasn't destroyed like the rest of the demons in the chamber with the two Hunters.
