Nexus of Realities
From Jenny Everywhere Wiki
The Nexus of Reality was a mysterious dimension consisting of a pale landmass with an infinitely tall skyscraper in its centre, which served as the headquarters of the Bureau of Singularity, from which they allegedly surveyed all other realities. Strings of reality attached each reality in the Multiverse to one floor of the skyscraper. The Director of Singularity himself had his office on Floor 239.
Time and probability worked differently in the Nexus than they did in Reality Z-25 31-H; “unlikely” events were actually more likely to happen than expected ones. Hence, a human of normal strength could punch through a wall while a superstrong suphero might fail to put a dent in it. (COMIC: Singularity War)
