Okay [@Zebra], so let me now explain what I was too tired to explain last night.

It's not good to think of it as a multiverse [even... though I said it was a multiverse idea]. It's easier to think of it as the bubbles I described. To think of it like a multiverse would be to think of only one of the small bubbles floating in the bigger bubble. The focus is on all of the bubbles and not just the one. Where the good guys exist in a realm completely devoid of, for a lack of a better term, magic, the greedy people would exist in a realm where that magic would thrive. They exist somewhere, it's just that they have no knowledge that the realm exist beyond their own universe. There are many different signs that show how and where the realms are being destroyed, the good guys just haven't noticed them. That is why they have no knowledge. And as far as them being in the "multiverse" as I think you understand it, the only other place they could be is outside the plain of existence, and they can't do that.
