War of Clashing Planes
The War of Clashing Planes was a conflict between two groups of Deities arguing over whether to protect the surviving life on the Material Plane or to destroy the plane in its entirety and start over. At least one hundred deities were killed in the war, but only a few of their names are still remembered today. The war spans the entirety of the Epoch of Clashing Planes, some 15,000 years.
