The World of Abstruse Skhedios includes the Origin which is the remains of the earth after a dimensional collision, the subworld is the Super Void connected to the Origin through the rift.
The Origin
As previously mentioned, The Origin is the remnant of the earth which also means where humans live.
After the Dimensional Collision, the sun and the moon vanish, leaving the earth in the dark. now the thing that vanishes the sun and the moon are everywhere spread across the universe, it's a highly unstable field called the Hofrez field. Everything within the field will dynamically change in a relatively short amount of time. Things will go in and out of existence on a large scale.
Fortunately, some parts of the earth don't get affected by the field, because within these fields there's always a stable space. That's where the human survivors live.

The Super void
Super void is hypothesized to be a place in between multiverse, or maybe a different place entirely we aren't so sure. What we are sure of is the supervoid is home to Living voids, a living universe, that can die and multiply.
The space within the supervoid was simply called intervoid space. In this place, teleportation is simply impossible, because there's no plane to bend into. There are no higher dimensions. Usually, you can bend the space to instantly travel from one place to the other but with the absence of space to bend, you simply can't teleport.
Besides the Living void, there's not much known in the Supervoid. At least that's all we know so far.

The Living Void
We don't know about how living void come to existence besides from other living void. We do know how they procreate or at least for the one we specifically study, there is a possibility for a different way of procreation, but who knows?
A living void is a conscious being to survive. The primary diet is the mind since the mind is one of the things that have high compactibility storage. What Living Void did is simply install, compile, and extract the mind from abstract to real things, kinda like what you do when downloading and extracting a program.
Because there is no mind within the Super Void, the Living Void needs another way to find a mind in this case using The rift, the rift acts as a bridge between the Living void and other worlds, we aren't sure how exactly the connection is made, we don't have much information about it, at least for now.
One world this specific Living void we study is connected to The Origin which we human is coming from.

The Other World
Besides The Origin, the rift is also connected to all sorts of places. It could be another Dimension, a new world, a different realm, some kind of plane of existence, layer of reality, but not connected to other living voids or at least that's as far as we know
We never try to enter rifts, because of how risky it is, we don't know if we can even go back after entering.
