I’d like to add a quick sidenote .

I wouldn’t read too much into the logic of mythological worlds and realms.

Their purpose is narrative, not scientific. They don’t even need to be internally consistent.

No one expects Greek mythology to make scientific sense. Other mythologies should be seen from a similar perspective and understood that they are narrative, not logical.

Applying a scientific viewpoint to such mythologies results in a new narrative. The scientific view is always wrong unless scientific correctness is part of that world’s narrative.

I add this because a lot of people don’t know narrative purpose.

To put it briefly:

Other peoples worlds aren’t wrong when they don’t match “what makes sense in the real world”.

So it's all just vibes?
