The Fae Invasion

The Fae invasion was a extra-planar invasion by a large number of Fae species that halted the God Wars, and nearly annihilated all life on Jushara. Lasting nearly 800 years, the invasion quickly turned into an occupation by Autumn Fae overlords, who used native species as cannon fodder in their war against the other Fae Courts.
The invasion resulted in the introduction of Goblins, Firbolgs, Pixies and many other fae species to Jushara, as well as the Elves, the progeny of Humans and True Elfs.
