The Cataclysm, the fall of the Tower of Eternity, that was what changed everything. Once, there was only human and daeva; a race blessed with immortality and wings upon ascending. At the head of them all were the Empyrean Lords, the first deavas to ascend. When these lords had tried to make peace with the race known as the Dragon Lords, or presently, the Balaur, an unknown assassin had tried to take the life of one of these and chaos had begun, resulting in the split of the Tower of Eternity. Because of this, the world of Atreia had crumbled into various sections, no longer connected.
Many years later, all had been changed by such circumstances thinking the other did not exist. However one day when one of the newly formed races, the sun-blessed Elyos had wandered into the other, the Asmodian’s, cold and harsh territory, a small battle had occurred that caused a war between the two races for the next hundred upon thousands of years.
