There was once a battle. A great war between those who called themselves gods who govern death and those who extinguished evil spirits. The conflict ceased in the form of losing their respective ‘kings’ by the end of this feud which spanned a thousand years. The relationship between Shinigami and Quincy will come to hail a new era triggered by this great loss on both sides.

It was said that it was the very same person who killed both kings, he was neither Shinigami nor Quincy, but only a small fraction of people are aware of that fact. The ringleader of the “Wandenreich”, a rebel army which invaded Soul Society, was defeated by a young Substitute Shinigami who was but a guest of the Gotei 13 ―― along with the proclamation that “the Gotei 13 successfully defended the Soul King Palace”, it was only this part of the story that continues to be propagated within the Soul Society.

In other words, it was decided that the very death of the "Soul King” who was the foundation of Soul Society, was something that would be permanently concealed with the aim to suppress confusion and disorder. Even now, many inhabitants of the Soul Society including ordinary foot soldiers, still believed they had their Soul King enshrined at the Soul King Palace.

Knowledge of the facts are limited to only a handful of Shinigami such as Captain ranks and senior officers, or those attached to important posts within the Seireitei; even they dare not expose the truth and disturb the people’s peace of mind.

From there, the revival of the Seireitei that was left utterly devastated, would begin.

As for whether or not the decision of the higher-ups, who did not deem it acceptable to snatch away the people’s moral support, was right in the end ―― that was something that will likely be judged by history ten, or a hundred years down the line. Ushering in the conclusion in such a way, the series of conflicts would subsequently be known as the “Protection of the Soul King Great War”.

While the war was over, and peace was to be known. What is an ending to some, is but the prologue for others. This was but the end of a chapter, but the beginning of a new story.
