In the vast and boundless universe, it is actually a gigantic Chaos World, where there are no roads, no light, no time, nothing at all.
And within this Chaos World, circles upon circles emerge, each circle being a different world. In this world too, the divine and mortal, gods and devils perform their roles, possessing many planes with countless populations, monsters, spiritual beings, demonic beasts, and so on.
Overall, a circle is a world in itself, isolated from the outside, to the extent that they are unaware there are more circles outside.
Tyler Nash entered a circle and came to an unfamiliar world.
Of course, it was only the environment that was unfamiliar; here the sky was still blue, the earth was still black, there were trees, flowers, grass, and even people who looked just like him, with some places having the same language too.
Tyler Nash fell from the sky, into the sea!
