Universe Prime

Universe Prime, or just "The Universe", contains pretty much everything that you can see.

Overview
The Universe is a large collection of super clusters that continuously expands ever since 13.5 billion years ago. It could be bigger, or smaller, it's hard to tell. The Universe also follows a specific set of rules that cannot be changed at all and only work in that Universe. There could be multiple Universes, but as far as we know there is only the Universe and the Esrevinu, which is still unknown on how to access it.
