The Mirror World

The Mirror World is a pocket universe that exists outside of the multiverse. It is the home dimension of the Mythrans.

History
The Mirror World was created by the First Builders during the creation of the multiverse. It was intended to be the home of the Mythrans and exists outside of the multiverse. Unlike other realities that are parallel variations of each other, the mirror world is a reflection of all realities. The Mirror World was left vacant for millenia following the first war of the nexus and the banishing of the Mythrans. During this time it was overrun with Anti-Imagination. After The Crux Incident and the release of the Mytrhans, they returned once again to the Mirror World where they continue to reside.
