In the fallen Angels kingdom, there was a large expanse of land floating high up in the sky.
The floating island was called 'The World Union Academy' and it hovered above the capital city of the kingdom.
The World Union Academy was built by the Fallen Angels as a way of promoting peace between all the races in the mortal realm and sharing the knowledge learned by talented individuals with the students of the academy.
These talented individuals were registered as professors and instructors within the academy with the goal of sharing the knowledge they had obtained during their battles and experiences with the students.
Their role was to guide the students under their tutelage and help improve their ranks regardless of the race of their students.
Currently, the capital city underneath the academy was buzzing with activity as it always did.
