In the beginning, God created several different worlds in order to create one that satisfied him, and Satan set out to do his best to cause ruin to these worlds. At long last, after tiring of each other (or perhaps to entertain themselves) God and Satan agreed to one final, long, tiresome game to decide the ultimate ruler of the universe.
To ensure that the game is carried out properly, God and Satan joined together to create a separate world specifically for the competition. Both God and Satan sent out their number one servant to play as leaders and lookouts to ensure that their sides follow the rules properly. Both Jophiel and Lucifer seek out worthy players for the game; and await the time to give out the competitions and tests that God and Satan have created. They even plan out the living arrangements for the players.
