Potential Academies are special schools that are run by Paladin. There are five spread across the country; their names are Nighbil, Virce, Grandilon, Highmark, and Wellings. Paladin set up a system to where when a 17 year old it tested by Trigen and finds out they will Change, they are then sent to one of the Potential Academies to learn how to control their Aptitude. They spend about three years at these Academies, and when it is determined that the student has sufficiently mastered their Aptitude, they are allowed to return to their normal lives, with a certificate, similar to a gun license, that states they have an Aptitude, but know how to control it. All Changed must attend these Potential Academies and get their certificate. When they return home, they can then live a normal life. Some students who show potential at the Academies are invited by Paladin to join the Squire Program. This is the program that train them to become Vassals when they graduate. The academies themselves are set up as boarding schools, surrounded by large prison like fences so no one gets in or out. At the academies, students are assigned to a Guiding Vassal who works with them one one one to develop and practice their Aptitude. Also while at the Academy, students take regular high school classes as well, and finish their diploma. Their weekdays resemble normal school in that they go from class to class.
