Void Cycle

Overview
The cycle of birth, death and rebirth that the Gods and all of sentient life have to endure because of the eternal conflict of the Shade and Allfather. Basically the Shade and Allfather exist as a single object (the egg) the Shade acting as a shell and the Allfather acting as the life inside, then when it hatches, the shade is connected to all the bits of Void Essense that break off of the egg, creating Beta radiation from all of it, eventually consuming everything and forming a new egg. The allfather goes out and creates life to eventually act as food for the shade to create a new egg to do the same thing forever, and all of the Gods understand this concept from the moment they are born.
