After Pateras, the Primordial God of Creation, found about the affair between Matera and Ultis, resulting in the birth of the primordial God Ornathon, he left his world, taking Matera with him. In this act of sheer anger and malice, parts of the Script, the very writing that makes up reality, were twisted, creating Eldritch abominations. The five greatest of these abominations are known as the Eldritch Horrors, and posses near God-like power, poisoning the world with their unnatural existence.
