The Oracle Academy, also known as the Five Heroes Academy.
It was founded by the five great heroes of different races after the Great War, 45 years ago. This academy was founded because of the prophecy made by the Great Prophet after the Great War that in the future, the chosen one will appear, who will lead a group of powerful companions and be the light that will save the doomed future of this world.
The prophecy said that in the near future, many catastrophes and disasters will befall Alnaur that will lead humanity to the brink of extinction. And only the one chosen by the world can save the future. That's why the five great heroes founded this academy in the hopes of training the future generation to ensure the survival of this world.
