Prior to the Islamic Empire's invasion of Egypt, faeries had been somewhat open with their powers in the area. After the invasion, fire faeries, who were the most publicly visible, were accused of being demons and jinn, and were driven south into the Egyptian desert. According to boreai mythology, in their rage the fire faeries retaliated by setting the desert itself on fire. Because their emotions were so uncontrollable and their numbers so large, they lost control of the fire. It grew miles across and burned for three days, consuming the faeries that had created it. The flames died out and revealed that the fae were still alive, but changed into light boreai.
