Many millenia ago, the God Aion create Atreia, a vibrant planet with lust landscape and bountiful pastoring as far as the eyes can see. The glorious Tower of Eternity provided anything they need for happy and carefree life.
However, this would not last. The Drakan, terrifying creatures whose thirst for power and obsession. Aion created these creature but couldn't foreseen how they devolved. The Drakan became Balaur, a new species hell bent on dominating on Atreia.
Aion somehow counter this event by blessing some humans with divine power. They became known as Daevas.
After years of ruthless fighting, both sides sought a truce, but in assassination which change the fate of Atreia forever.
Atreia now divided into two part. Elysian and Asmodae. The light from nearby star bent in glorious synergy, enabling the inhabitants, the Elyos to prosper.
Meanwhile, the Asmodians in the upper half of the planet suffer through endless darkness, and cold, and merciless landscape.
These opposing races must now face each other and confront the terrifying Balaur if they hope to control the Fate of Atreia.
