From nothing was begotten the Primordials and nothing more existed until they chose to exercise their powers.
With their will, stars, black holes, pulsars and solar systems were created. They created living creatures and later on, they created the first set of sentient life forms that unlike the others would experience and perceive the change of the cosmos.
It wasn't an overstatement to claim they were the all creating, encompassing beings.
However, there were things they had no hands in and one of those was the birth of the gods.
The existence of these unprecedented powerful beings piqued the curiosity of the Primordials, something that hasn't happened in eons.
First came Ahura Mazda, and then others came as well. Nana Buluku was amongst the first of the incipient ten that was created from the aspects of the world.
Over time new gods started to appear and many revered the first ten gods and took abode under them.
