The Metareality Web/Reality Cluster is a web of our local realities. The box, the Omniverse, and the Primordialverse, which are connected by the Metareality Core, are central to the web. Each reality has at least one existance state.
If you in the voids of the Web, then you will dissapear; you aren't connected to any realities, which hold existance states together, so you don't have a valid existance state. You can phase through anything now, as you can't interact properly with existances without an existance state. You can't even see anything; you just see a giant black void.
Metareality Links
A metareality link is the web itself that holds the Metareality-Web's Realities together. They are made of Megons, a particle which applies extreme force on existance states in order to rotate them around and switch them. This process takes about 0.0000001 planck times.
In the center of a link, holds a Metareality Hub, most of these hubs contain high level civilizations that have moved there, as each hub yields little Information Bubbles about each reality.
