Over time, those with merit and power gained "Benefactors" within the school. As the population of the Academy grew, the power that said people and benefactors grew as well to match armies, some say.The time came when one attained such a level with his allies, calling them a "Legion," like how demons would refer to themselves. Many more of these legions formed and grow to rival the first. Only 5 could have legions of similar strength. They were all referred to as Power itself, or "Exousia" The ones with these titles were recognized as those who could rival the instructors because of the sheer numbers that could overwhelm them.
A day came as one Exousia, prideful enough to carry the entirety of his legion with him into warzones, and dangerous missions challenged all the instructors to decimate them all with his own power alone. He was called the First among the Exousia, and his will would shape the academy to the place it was in the future.
