Universal Overlap
From The Monoverse: A Non-Linear Sci-Fi Epic
Universal Overlap is a type of Dimensional Decay.
Universal Overlap describes the inching of multiple universes onto one another, as if they all exist in the same space at those points of overlap. A Universal Overlap makes it possible to enter into any of these dimensions, depending on the direction you go while occupying a Universal Overlap.
A Universal Overlap is usually a pre-cursor to Universe Bonding.
