Revolution
The Drow family, largest of the elven families, starts a rebellion.
Tired of the high elven queen's Silver bloodline, the Drow family starts a rebellion to attempt to usurp the throne. They enlist the help of a dark god to gain more power than their high elven siblings, and succesfully kill the queen. Desperate, the high elves seek out the Church for help, and Gilgamesh marches an army on the Silver Spires, and forces out the Drow family, banishing them from the lands permanently.
