Orbinverse

The Orbinverse is a verse that contains two main objects: the End of Chain and the End of Chain's polar opposite, the End of Darkness. Both the End of Chain and the End of Darkness orbit each other in an elliptical motion, while everything else is surrounded by a very large void.

Ancient Section
The Ancient Escape ship, which didn't use a indescribability drive, was actually stuck in the Orbinverse for a while, and only escaped around $$\omega^\omega$$OYC before us. We are still unsure why it would've taken so long, but it's just how history goes.

Recent Section
After escaping the End of Chain, the Escape crew got into the Orbinverse and escaped the End of Chain. It seems that the surface of the 'final' layer of the End of Chain had a lensing property that allowed for sight into the very middle of it.

The End of Darkness was located, and was named that way because it emitted so much light that it acted almost like a white hole, with photons actually pushing the ship when they got within around $$\Omega$$light-OYC s of it's 'surface'.

After research, a station was made, and after some measurements and a new ineffability drive, the crew escaped into the next verse.

Composition
Other than the End of Chain and the End of Darkness, the Orbinverse's void is actually full of weakly interacting particles called Kappa Particles that cause turbulent motion near the center of the Orbinverse, lowering the energy of photons in certain ways to make light slightly blue.

Further out in the Orbinverse, these particles barely move at all, causing a spherical 'wall' of Kappa Particles to form, which is tough to pass without certain drives (like the ineffability drive). This sort of structure makes many shells of Kappa Particles around the verse, where particles move the least.

Etymology
The name 'orbinverse' came from the two words 'orb inverse' because from outside the End of Chain, it looked like an orb, and so the inverse of an orb is whatever isn't where the orb is. The name became Orbinverse, even though it actually contains the End of Chain.
