The Lost Light
In what is generally known as the Last Day of the Third Age, an event known as the Cataclysm changed the face of the multiverse. In the blink of an eye, the gods were wiped from their homes in the Outer Planes. The loss could be felt throughout the multiverse: those with strong divine connections died off; the most devoted worshipers had their souls sucked from their bodies, leaving them dead, insane, or, worse, transformed into vile abominations; and those with the will to withstand the tremendous hollowness in their souls found themselves without a reason to live, and often took their own lives or wandered aimlessly through the world.
Over the thousand years since, mankind has found a way to survive, yet still longs for the peace of knowing that there is someone powerful out there watching over them.
