The Academy is one of the oldest facilities in Erah. It's not only a school, but also an organization always led by the greatest warriors from worldwide, not only to train the bests of the next generation, but to keep peace in the world. Their missions are always created to help the others, but not only other groups or nations, but every other people in Erah. Being an academian is an honor, as only a few can tell from themselves that they achieved the academian title.

The Academy was created after the First and Second (Arch) War to keep peace in Erah at any costs. The uninhabited middle island was a perfect place to create an organization there with the best warriors of all the nations. However, as they were thinking about the future too, they decided to make it not only a group, but a school, as there they are training the next generation of the protectors.

The Academy contains 3 different houses/classes, where all the students are assigned: Red, Blue, and Green. All of them are different and contains students depending on the color of their soul. The Red contains students whose are optimistic, and related to the nature and spiritual things. The Blue contains pessimistic person whose are more related to the mythical and "magical" things. The Green contains students whose are realistic and they are related to science and technical things. Every student are assignated to one of the classes as soon as it is determined if their application is accepted or not.
