What is this place?
At the edge of everything, there exists a border. The border between reality and fiction. This border prevents chaos, destruction, and absolutely insane things from happening. This border is also the inner wall of the Absolutely Everythingspace. This space is the container of all that is, and all that is not. This is one of the most important verses, as described previously, and is also where gods are born. This verse contains 4 walls. There is the reality wall, which is the edge of reality, the fiction wall, the wall which is the edge of all that is not, the border of all, which separates the two spaces and is also the one mentioned earlier, and the meta wall, which separates all the spaces from the outside unknown. If these walls were to disappear, then everything inside the Absolutely Everythingverse would cease to exist in about 33 plank seconds.
What is outside?
Outside of the Absolutely Everythingspace is everything that is too powerful to be contained. This includes beings like guy and spaces like The Outiumside. This is why everything inside would be destroyed so quickly, as so many powerful things would obliterate the beings inside. The only reason why the walls don't collapse is that the gods are holding it up.
