If you are within the void of the Web, then you will disappear; you aren't connected to any realities, which hold existence states together, so you don't have a valid existence state. You can phase through anything now, as you can't interact properly with existences without an existence state. You can't even see anything; you just see a giant black void.
Metareality LinksA 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 existence 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, which can give the civilization near omniscience.
