Ersis is the over-realm meant for keeping the Seeds safe from the Lathrym's inhabitants. Since the Hethe have abandoned this realm, the Ythen are in-charge. This is where Humanity lives and thrives within the Seeds
The Ythen (pronounced: Ee-thin) were created by Fab'ras to maintain the Seeds while the Hethe are powerless. They appear as giant humanoids, with a pulsing, galaxy-like skin. There are multiple Ythen, but only a few of them are active. They can be contacted and talked to by Arkn and Dekn, but usually will not convene with humans unless under a special circumstance. Ythen will watch over the Seeds and regulate Arkn and Dekn traffic into them as well as providing the necessary transmogs for them, les they go in unregistered and "illegal". Alongside this, they deal with any sort of offender, Arkn or Dekn, with a harsh punishment if the offender starts any sort of conflict that may out the existence of Arkn and Dekn within the Seed. Each Ythen holds the entrance to a prison-like realm known as Tartareous inside of them, and will consume offenders of the Seeds, damning them within this inescapable realm. As far as it is known, Ythen can not be harmed or killed through conventional methods, and because of this, most creatures generally do not violently confront them
Seeds are mini-universal orbs that contain Humanity. They were created by Fab'ras to house humanity, while Ced'ric protected them until assigning that task to the Ythen. While initially there are five main connected Seeds, any Seed discarded deemed unfit can also house active life, unless entering its apocalypse state. In order to exit the seeds, one must go through a wormhole located somewhere randomly in the seeable universe.
The Five Seeds are known as
- Courn (Seed 1)
- Hecc (Seed 2)
- Ifred (Seed 3)
- Xren (Seed 4)
- Big (Seed 5)
Anytime one of the Seeds is deemed too unfit to stay connected, be it through Arkn and Dekn tampering gone too far, or catastrophic events occurring, it is copied to a time before the event occurred, while the copy with the event in place is pushed away from the five, set to orbit around Ersis. Orbiting unfit Seeds are known as Outliers. These Seeds can still develop, unless they hit an apocalyptic state and are destroyed. All Outliers will eventually hit an apocalyptic state due to not being maintained by the Ythen. When and how is mostly random. As soon as a seed hits outlier state, it is immediately under the jurisdiction of SEEKER, which handles the Outlier seeds and is often in charge of wiping them out.
Humanity developed in Universe X due to the blueprints already existing within .Mainframe. De'ebolus used the last of his power to kickstart their development while Fab'ras protected them inside of the Seeds. Originally, humanity was meant to stay within the Seeds, but due to LUMERIC discovering the exit from the Courn Seed hidden behind Earth's moon conveniently, they were able to exit and evolve beyond the Seeds. In addition to pure humans existing within the Seeds, Arkn and Dekn that have mingled with humans may create half-breed offspring that live among humanity. These half-breeds contain some shard of power from their Arkn, or Dekn parent, and can easily move about Humanity without being discovered unless their powers are seen and spread.
