The Elven War is a series of conflicts spanning roughly 2000 years. The war ended with the Battle of Latiran between the deities of light (the Ellesentiri) on one side and the dark deities and their allies on the other side. This battle was won by the deities of light and resulted in the banishment of the dark deities to the depths of the Abyss. Shortly after, their followers (the predecessors of the Drow ), shorn of the power of their gods, were banished to the Underdark by the armies of the Ellesentiri. With a powerful weaving of magic, a combination both of godly power and High Elven magic, they were sealed away.
