Hello Ultima, a question
If a universe is declared a Higher dimension (regardless of whether it refers directly to a actually higher dimension of space, I mean a Higher Plane of existence, not a metaphor or a Flowery language for something like advanced. tech or similar) to explain the role it serves as the "interdimensional highway" which allows access to all universes of the lower dimension that threaten all existence, while also containing those universes (countless possibly infinite) in the form of much smaller finite objects like ordinary planets and trivialize it to the extent that it can be destroyed from there like normal planets instead of special pocket universes or similiar , besides it is even inaccessible by people who can access everywhere of space and time, including coutless possibly infinite universes and everywhere of it, then they are even reach further on "dimensions beyond their grasp before" and The place/realm transcendent and separate from space and time
Would that Universe qualify for Low-1C, and the "dimensions beyond their grasp" I mentioned too?
