History of the Valley of the Gods:

It is said that even the powers must cavort and amuse themselves once in a great while. Far to the north of the Spine of the World is the Valley of the Gods. A paradise unequaled on this world or in the planes, this playground of the gods is not meant for mortals. Any mortal who reaches the Valley becomes a deity, for only deities may exist in the Valley. Far too many mortals with delusions of grandeur have thrown away the pleasures of this side of the Spine and their kingdoms in this world, only to break their backs searching for the legendary Valley of the Gods.
