According to Ichibē Hyōsube, over a million years prior to the Soul King's ultimate demise, all of existence was a single, chaotic, primordial world overrun by
Hollows that preyed upon the world's denizens. When said Hollows started to evolve into the first Menos, the being that became known as the Soul King first emerged, "born"
as if the world itself rejected the Menos. To protect the inhabitants of that world, the Soul King proceeded to annihilate all the Hollows that preyed upon them, temporarily stabilizing the world's decline.
