For thousands of years, leaders from cultures all over the world have been trying to bring back the Gods. Through secret societies, the teachings of the Me, and findings from ancient cultures, they maintained the knowledge that the Gods were powerful, and real.
Those in charge built great monuments, imitated ancient structures, performed rituals and sacrifices, developed technology, searched for objects of power, all to find a way to communicate with the Anu and tell them “We are here, we still serve you, come back and help us.”
They hoped that when the Anu returned, they would be rewarded with great power, and would rule the world. Although the common people would suffer, the ones in charge would benefit immensely.
