In the great chess game the Anu played to battle each other for power and influence, humans became the pawns. Humans were taught to fight each other, to hate their neighbours, to send their children into war, all in the name of the Gods.
Over the course of history, many religious battles were fought between the armies of rivalling Anu.
This is the time where the rise and fall of human empires was driven not by a human motivation to expand, but by the madness of the Gods – who often got actively involved in organising wars and providing their side with tactical advantages.
