Unification Wars

Also known as the Unity Wars, where the wise masters overthrew the gods and established 500 years of peace.

Tyriads History of the Unity Wars
Sometime between 1400 and 1500 DR, a cabal of powerful magic users came together and decided that they had had enough of watching the suffering of mortals at the hands of the gods. During that century they established "The Order of the Wise Masters" to find a way to ascend to the status of God hood and end this suffering. Unfortunately they were unsuccessful in this endeavor, but with the onset of 'the silent plague' and the emergence of the Voy'Nix they found that they could build an army capable of unifying the world against the gods. After many decades of battles both open and in the shadows, they managed to weaken the power of gods enough to trap them inside something known as "the soul forge" where the very essence of their souls would be reduced to raw energy. The power of this item was enough that they even managed to nullify Ao, and so began a new age of peace, free from the machinations of the gods.
