I'll try to explain. So There is this universe, and then there are other universes. Lets use Universe 2 as an example. Universe 2 exists almost completely outside of our own. However, there are places where the borders of these 2 universes just barely touch enough to enable crossing between them. Most of the time, the only places these universes can come into contact will be small, isolated fragments, separated from the main framework of a given universe. Though sometimes you may be able to cross into more expansive parts of other universes.
There are also what I have dubbed Extraverses, too many to count as a matter of fact. An Extraverse is a universe that exists outside of our own, nothing new to you at this point hopefully. However, the borders of these universes are one-way only. You can experience a part of them, but venture any further into these universes than the piece that is connected to our own, you will not be able to return, and will have to find your way back here by yourself,
Did you hapopen to stop and smell the flower on the way here? That was a zone in an Extraverse. You may have ventured further into that unverse and found yourself completely separated from the one we are currently in.
Even within universes there are secrets. To even get to this point, where you are speaking to me, you had to follow a Hidden Path. Hidden Paths are paths that exist and are traversible by default, but may not be obvious to you at first glance. There are many ways a path can be Hidden.
And finally, there are Broken Paths. A Broken Path is a path that, within our own universe, is completely inaccessable. Sometimes, a path may be Broken due to it simply having always existed that way, or may have at one time been a functional path but has ceased to work within the laws of our universe. However, other Broken Paths may be able to be repaired if you can find a way to alter the fabric of our universe.
At the moment, the universe seems completely stable. I'm not sure what causes things to shift like they seem to sometimes do. It's almost as if a being with much greater power here than I is constatly deciding the shape of this world. This being seems to be lying dormant for now. If you ever want to check on the status of this place, return here and speak to me again.
