I agree with VeryGoofy about the Monitor Sphere. The Monitor Sphere is not a spatial dimension. It was the thoughts/stories of the Monitor Mind given form. Grant Morrison even stated that the last realm that is within DCU is Limbo while the Monitor Realm and The Overvoid are archetypal realms that exists beyond it (Grant has grouped Nil and the Overvoid multiple times, emphasizing them both to be archetypal realm beyond the multiverse)
The Monitors basically are beings of pure thought, thoughts of the Monitor-Mind. When the Monitor Mind sent its first probe to examine the flaw, the Monitor-Mind was shocked because it doesnt know about the concept of "story", the probe split into two and the flaw was scabbed over with divine metals, the Though Robot is what remains of the first contact, the Thought Robot infects the Monitor-Mind with questions and speculations which sparked the race of
the Monitors.
When the Monitor-Mind discovered the "Flaw" it created a concept to contain it:

| GM: As we saw in Superman Beyond #1, the original, infinitely vast Monitor-Mind created a ‘concept’ to contain and study the Multiverse. That concept – a structure known as the Orrery of Worlds – was designed to protect Monitor from the effects of the Multiverse, like a bandage over a wound, or, perhaps, a cage around a wild animal. |

If the Overvoid is the "Monitor-Mind"
the Monitors are its "thoughts" created to protect itself against the story of DC that is staining its perfection.

| GM: In the case of comic book stories, it's the war between white page and ink. And who's to say that the page might want that particular story drawn on it? [laughs] What happens if the page is a bit pissed off at the story that's drawn on it? So I thought of the page as God. The idea being that the Overvoid – as we called it in Final Crisis - of the white page as a space is sort of God. And it's condensing stories out of itself because it finds inside its own gigantic white space, self-absorbed pristine consciousness, it finds this little stain or mark, this DC Multiverse somebody has 'drawn'. And it starts investigating, and it's just shocked with what it sees, with all the crazy activity and signifying going on in there. It then tries to protect itself from the seething contact with 'story' and imagines a race of beings, 'angels' or 'monitors' (another word for angel, of course) to function as an interface between its own giant eternal magnificence and this tiny, weird crawling anthill of life and significance that is the DC Multiverse. |
The story of the Monitors was created by the Monitor-Mind itself, the story of the Monitors is the Ultimate Story of the Monitor-Mind.
| GM:: No. Monitor-Mind has worked through its own Ultimate Story and spared Nix Uotan to be its sole representative and interface with the Multiverse. I see Uotan’s ‘hyperhero’ role in the DCU as a cross between the Silver Surfer and Doctor Who (particularly the Earthbound Jon Pertwee iteration of the character). |
The Cosmic Clock (see the sky in Monitor Sphere are made of clockworks) contains the Archetypal World world of Nil around the central multiverse
So yeah, the Monitor Sphere isn’t a place in space or in the multiverse — it’s conceptual. It’s the thoughts of the Monitor-Mind (aka the Overvoid) given form. The Monitors are basically ideas or mental constructs created by the Overvoid to shield itself from the "Flaw" — aka the DC Multiverse, which is like a stain of narrative chaos on its perfect, storyless being.
When the Monitor-Mind first encountered the Flaw, it didn’t understand "story" and was basically infected by it. Its first probe split into the Monitor and Anti-Monitor, and the Thought Robot (Superman in that higher form) is what’s left of that first contact. That first infection led to speculation, identity, and eventually the birth of the Monitors as a race of conceptual beings meant to study and contain the Multiverse.
The Orrery of Worlds is the structure it created — like a bandage — to hold the Multiverse at a safe distance. Limbo is the last "place" within the DCU — everything beyond that (Monitor Sphere, Overvoid) exists in a metafictional/archetypal space beyond story. The Monitor Sphere is the interface between the Overvoid (pure thought, no story) and the DC Multiverse (a chaos of stories). For it to function as a buffer, observer, and containment system, it must exist outside the Multiverse — not within it — just like a computer interface isn’t part of the program’s code, but a layer that allows interaction with it.
Basically:
Overvoid = Monitor-Mind (blank page/God)
Multiverse = Flaw/stain (story/ink)
Monitors = thoughts of the Overvoid, made to deal with story
Orrery of Worlds = containment concept (a “cage” for story)
