The rivalry that existed between the Divine and Devil Wheels was a tale even older than Salem Theocracy and Judah Dynasty, both of whom currently held monopolies over each Wheel.
Just as the Devil Wheel held seven domains corresponding to the seven deadly sins, the Divine Wheel held seven domains corresponding to the seven core virtues.
They served as the perfect poster children of the concepts of yang and yin, which were essential to the presence of Balance on Eventide.
With the Virtues presiding over the Divine Wheel and the Devils presiding over the Devil Wheel, they were opposites in every way possible, ensuring that there could be no chance of ever coming together.
In any case, due to this peculiar rivalry that had stood the test of time, waxing stronger as the years went by, the denizens of these two enigmatic Wheels had gotten the opportunity to study one another extensively ensuring that there were no secrets between them.
