The hollow space that exists between all the universes of the multiverse.

Cracks in space-time happen here often, letting in various objects from all kinds of different realms. Usually only small stuff comes trough, but occasionally, bigger fissures will bring in much MUCH larger things like large landmasses or entire stars.

Outside the mess of multiverse souvenirs, the only thing to see here is the endless mist of pure infrared and ultraviolet light, occasionally populated by landmasses of black and white checkerboard tiles. Every time a universe is born, another tile appears somewhere in this dimension. White tiles for matter universes and black ones for anti-matter universes, their lengths corresponding to the size of the universe they represent.

Within the vast emptiness of this space however, there lurks a soul.

Its unknown how and why, but this place is alive and conscious. And while it doesn't need to exist in a corporeal form, sometime still, it chooses to manifest as him...
