Legend says that all universes are connected through the Nexus, a spiritual waypoint located on every Earth in every Universe known to exist. The creator of the Nexus is Celesteon the Primal King. He has existed since before the very beginning of the Multiverse. He formed the Nexus as a wellspring and spiritual center when their was but just one Universe, the First Universe. Celesteon, or Hanuman as he is known now on some Earths, is a living manifestation of cosmic order. The being responsible for the movement of the Heavens. Celesteon, the other Primal Beings that serve the Heavens and his Preservers (a race of beings known to be the first species to develop intelligence in the First Universe) all exist as singular entities within the multiverse. It was a Human named Shakyamuni from the 1st Universe that questioned the Heavens and confused Hanuman. In his anger he became Collaspsar the Devourer, the chaotic Sun Wukong, a mockery of his former glory we now call the Monkey King. With the help of the Heavenly Primals Shakyamuni imprisoned Sun Wukong within the Cradle of Lore. Angered by his actions the Preservers of Celesteon laid waste to the 1st Universe, killing quadrillions of intelligent beings. Only a handful of humans, sheltered within the Nexus survived. They called themselves the ZenKai. Those survivors witnessed the Primals form the Multiverse, many Universes that reflected and evolved from the ruins of the first. In order to prepare the Multiverse for the day that the Devourer may escape his prison seeking revenge on all universes the Zenkai used the Nexus to find and train champions on every Earth. For thousands of years these champions have trained, honing their fighting skills with each other for the eventaul return of Sun Wukong. That time, has come. The Heavenly prison is empty. The Cradle of Lore has been rent asunder across all universes. The Devourer is free. Knowing this the ZenKai long abandoned the Nexus and now are forcibly subjugating Earths in order to avoid his vengeance. In their fear of the Monkey King's wrath they have lost confidence in the principles of the Nexus champions. They have abandoned the rules of martial contest in favor of domination, subjugation and conquest. It is also whispered that They seek out the reincarnation of Shakyamuni, an orphan ZenKai said to exist somewhere in the Multiverse. They hope to recruit him or her or sacrifice them, the rumors are unclear. The Heavens remain silent. The Preservers have reluctantly pledged help but have done nothing. The ZenKai must be stopped before they kill every person on every Earth in order to find the lost ZenKai.
Which is why the Treul is here on this Earth.
Ringo believes that Shota may be the lost ZenKai.
