Countless years ago, the world was one where neither life nor death existed, where there was neither progress nor retreat. Even becoming a Hollow was part of the Reishi cycle. But Hollows gradually began devouring humans, and from then on, the cycle came to a complete halt. If this continued, all souls would eventually become one enormous Menos Grande, and the world would fall into total stasis. Then, the Soul King was born. Using the power of Quincy extermination, he destroyed the Hollows and set the world cycling once more.
