Earth in 2021, but a different one: the Millennium of human civilization has reached its endpoint and history has stalled. Three factions are locked in unresolved conflict — the demonic, the angelic Kells, and the mechanical Cybers — with no side able to claim a decisive advantage. All factions are looking for the Infinita Sacrament, said to possess the power to determine the shape of the next Millennium. An independent organization called The Agency was created to find it first. The player has just joined as a new Agent.
