The Mirrorplex is a land, very often chalked up to myth, that's brushed off by modern scientists when discussing mirrors and their relationship with the multiverse. Anyone even dipping their toes into the water of Cletanism, as well as high concept science and quantum research would know about multiversal mirror theory, but to summarize, it states that mirrors aren't simple reflections of your physical form, but are instead portals to identical universes, sealed off by an unacceptance of true reality, and a blindness brought on by negative emotions and dark eneries within your soul.
The Mirrorplex is a theoretical concept based on these principles... Which asks the simple question. What if there was a world between worlds? What would a world of infinite mirrors look like?
