This is not a region in space. Like the Toadeverse, you need access to enter here. Its size is larger than infinity, and there's no escape from it. This is because, it's before time. It's before even existence. The color white surrounds the whole area. If stayed long enough, you may come across Illuminati, because he lives here too. He actually owns this location.
The Dark Side
There's also another side to this place. It's darkness. Error Weegee was sent here. Voices can't be heard in this place.
