War of the Worldreaver

The War of the Worldreaver was a massive conflict between the Achaean Pantheon and Bal'met, the alien God known as the Worldreaver, as well as uncountable mortal forces on both sides. It ultimately resulted in the destruction or departure of a large swathe of the Pantheon, the fall of Shallam, and the defeat of Bal'met upon the plane of Nishnatoba.
