Flame of the World

The Flame of the World is a magical fire that burns in a shrine in 1000-Eyes Desert. According to myths, the Egyptian Pantheon created the fire, and through it, were able to establish a link into the Crystal Sphere, to aid their followers who had fled to the Crystal Sphere following a catastrophe in their native world. According to these myths, should the Flame of the World ever go out, the Egyptian Pantheon’s gate into the world would be closed, and they would be cast from the Crystal Sphere. 
In reality, the Flame of the World was conjured not by the deities themselves, but by their followers, when they arrived on Okarth in –2,045. It did indeed serve as the Egyptian Pantheon’s window into the Crystal Sphere, however. Should the Flame of the World go out, it is likely that the al-Bed Pantheon would not be cast from the Crystal Sphere, as they have existed long enough to be considered native deities, at this point.
The Flame of the World is guarded by priests and lay servants of the entire al-Bed Pantheon. The normal problems that these priests, priestess’ and lay servants have are ignored, because of the dire importance that the al-Bed people believe the Flame of the World has.
