The Watchers Edit
The Watchers can travel between the Bongoverse, Slenderverse, Nationverse, Star Wars and the Brotherverse. They cannot travel into the Jeulinverse because the Immortals created an impenetrable magic field around it to prevent the Voidaks and Mongo from entering.
The Voidaks live in between the universes. They can arrive in any universe in the Multiverse by tearing a hole in space-time.
