The Almighty/Expanded Universe

was the unique ability of the Soul King. It was eventually inherited by his son, Yhwach.

Description
The Soul King's signature power, The Almighty granted the being nigh-omnipotence and nigh-omniscience, allowing the Soul King to see all possible futures and control them. The precognitive powers of The Almighty seem to have no limit, as both Yhwach and Ichibē Hyōsube theorized that the Soul King had foreseen his own death, even millions of years before it happened.


 * World Splitting: Through the Soul King's The Almighty, the ancestors of the Five Noble Families were able to split their primordial world into three new ones, thereby creating the cycle of life and death.


 * Soul Regulation: After creating the three worlds and splitting life and death, The Almighty regulated the flow of Souls between the worlds. Without the Soul King, or rather, the The Almighty itself, to serve as a linchpin to maintain said balance of souls, the three worlds would once again merge with each other.
