ONE

ONE is the creator of the twelve universes and the lynchpin of the world. He is also the father of the The Celestials.

God Stone
Afraid that he may someday turn evil and destroy his own creations, ONE divided his power into six God Stones and spreaded them across the universes

Omni-Crests
After realizing that the future apocalypse that he saw will be due to Yhwach, ONE created the Omni-Crests which will have the power to seal Yhwach away. He then entrusted the key to the Omni-Crests to Seraph's disciples: Sosuke Aizen, Kisuke Urahara, Albireo Imma, Zhuge Liang, and Taigong Wong. The Omni-Crests were sent to another dimension to be guarded by the Transcendents.

The Sealing
After making all of the preparations for the future apocalypse, ONE sealed his soul core in the Void Space to prevent Yhwach from finding him.
