The gods and ascended powers of Quartus are not a mystery. Other than the Four, the oldest god is just slightly over 200 years old. The entire pre-Cataclysm pantheon (again, except the Four) sacrificed themselves to prevent the Cataclysm from destroying the planes themselves. All of the current gods ascended from mortality after the Cataclysm. The youngest of the major gods is about 150 years old.
