Multiverse



The Multiverse within the world of The Inmost Dens is the collection of every single universe that has been created by the Sysadmins. In reality, it is a network with its universes collected in different folders, with directories being everything else inside. Only one universe exists outside of the Multiverse, known as the Sysadminverse. The majority of events within the story of The Inmost Dens takes place within the Multiverse.

How a universe is destroyed
A large part of a universe's World Administration is dedicated to making sure the universe they inhabit is not destroyed by beings, or viruses so to speak, attempting to take over or destroy their world. Should the admins fail, typically they will be able to respawn to continue the good fight. However, some of these destroyers wield weaponry referred to as "Admin Slayers." These are weapons or individuals equipped with enough power to outright kill World Admins permanently. Such entities are considered highly dangerous and a risk to all individuals, and therefore all instances are either depowered or destroyed.

Sysadmins do not require an Admin Slayer to kill World Administrators.

Another method?
The only known alternate method of destroying a universe is for one of the Sysadmins to simply delete the universe's directory from the Multiverse. No known instances of such have happened so far.

Mainverse
The majority of events within the Multiverse take place here. It is the home of Neo Robloxia, also known as Earth, as well as its predecessor planet Robloxia, which has been long abandoned. All universes are connected to this main universe, so if the Mainverse is destroyed for any reason, the entire Multiverse will go down with it.

Warverse
A harsh environment with only two known inhabitants so far, both of which are World Administrators. It is described as constantly being in conflict until very recently, where the majority of the universe has gone silent.

Doe's Universe
This universe, long destroyed, was the home universe of several characters, including Percival and the eponymous John Doe.

Falloutverse
Presumably, this is where the games of Fallout take place. Only one World Administrator so far is in charge of this universe: a package courier going by the name of Advance.
