*Millions of years ago*
There were four powerful elemental deities:
Water goddess Aida
Earth goddess Xenia
Fire god Orson
Air god Arlo
They came together and created a world out of chaos. They each had their respective empires ( Euphrasia, Devika, Caitriona and Avalon).
Not long after that, they created their descendants who control elements just like them. Soon they realised that training was still needed to help them grow so an academy was created.
AXOA Academy focuses on the four foundations of all elements which are: Spiritual aspect for Water, Physical aspect for Fire, Intelligence aspect for Earth and Psychological aspect for Air.
All these are required for each person to cultivate an element. It was the only way for them to have a strong foundation because they were not deities!
Their descendants grew rapidly and they realised that it was time to ascend. Before they left they made their descendants the rulers of each empire, to rule over the common people. The common people were created not to have any ability but the deities still bless them from time to time.
Everyone lived in peace under the rule of the descendants until war broke out. Each empire wanted to control the other. This forced the deities to descend again and create something, that they would live to regret and ... fear!
