Discord

One of two historically substantial chaotic beings, Discord manifested itself in the form of Pazuzu, a demon prince. Through his influence, the Triumvirate was able to form and sparked the War of Humanity, in which Chaos was able to gain a foothold in Creation.

Discord challenged Proteus at the beginning of the Chaos Wars, and shortly after, its brother Entropy joined it. When Ayar, the Creator, realized that His creations were about to be destroyed, He dispersed Entropy and Discord all about Creation, adding chaos to it. The Plane of Chaos received the bulk of this dispersal, though chaos everywhere increased.
