Think of it like this Nirn and the area around it is in a bubble. That bubble has edges to atherius and one edge to oblivion. Each oblivion realm has there own bubble and no other bubble can join that already existing bubble. Atherius has one known Sovangard the rest is just atherius, they're could be more but we just don't know.
