The Abyss

The Abyss is the dark chaotic void that exists beyond the material world.The Abyss is not the Ethereal of Shadow plane and exists beyond Space among the other Planes.

When the Deities entered this Universe from the Pre-Verse, the Demons of the Abyss already existed in the chaotic void of space, however, the Demons did not know of the Deities until the creation of the first ordered world.

The demons, seeing this ordered creation as the ultimate perversion and feast descended upon it bringing forth chaos. Through the demons the races the inhabited these first planets tore at each other and devastated their worlds leaving nothing but darkness and chaos.

The Deities seeing the damage that the demons wrought, chose Nerull to be their vanguard and defend their ordered creations and for endless eons Neull did so, but the sheer number of the demons overwhelmed him, and many of the worlds were razed. Seeing this happen time and time again Nerull snapped, and joined the Demons seeing chaos as the true order of the Universe, and the Deities as the ultimate perversion.

The demons readily accepted Nerull among them and chose him as their leader, and with his power they went forth as a great legion and brought chaos upon all of the Deities creations. The Deities stunned at the lose of their brother created one final world as a last act of defiance, and this world, Akeroth, would be their most perfect and most protected. After Nerull entered onto Akeroth, he created Man, and from this point Man would be sent for onto Akeroth and quickly the situation would devolve into the Battle for Akeroth.
