During the dark age of the Ivory Empire, the Archdemons of the Abyss ruled Pelatoria with an iron fist and all humans were enslaved under their power. Their servants the Ebony Witches hunted down any who dared to stand against the empire, and both demons and abyssal aberrations roamed the world freely.
No one truly knows when the Ivory Court rose to power, but their empire is said to have lasted for a thousand years.
