Final "level" of existence, there's nothing beyond it.
The Corridor of All-Creator (The Edge of Reality, Palace of "his" Existence) - is the "room" where The All-Creator exists and observes The Black Noise, and "he" is the only one who exists here. The reality itself doesn't exist beyond the corridor. The Corridor of All-Creator. It has the purpose of observing and sustaining Our Existence
As The Corridor of All-Creator is the edge of the whole reality, meta(non)(anti)existence, all cosmologies, everything outside is cannot be described
