Heyo.
I'm sure this may be a bit random, but I didn't see any good Kingdom Hearts posts to throw this new information at, so i figured you may at least find this entertaining. First and foremost the new canon information confirmed (or I should say it
further confirmed) what I had previously said - while the Realm of Darkness IS a separate space-time from the Realm of Light, they are still a part of "The World". So Xehanort's attempts to rewrite the universe at the end of KH3 would have been at least Low Multiversal. Even better, it also confirmed that this included the Realm of Sleep as well (and others). Back when 3 came out, I remember some post where we tried to argue that, but others didn't want to listen. Well, the series reconfirmed it now.
And while I was surfing through posts that might be relevant to post this to, I saw a couple of your other posts talking about individual worlds being possible universes. One thing in particular I noticed is that you mentioned the Sleeping Worlds having their own flow of time, and how this may apply to the normal worlds in the Realm of Light as well. Just writing to say that was also confirmed as well. Each World has its own flow of time/time axis, as
Xehanort himself confirmed.
I myself am still iffy on whether the worlds are simply "planets", or whether they are actually entire universes condensed in a pocket dimension. I've seen evidence on both sides of the fence. I made my own little thread about it. Think I need to update some of the links, but still, it's
HERE if you want to give it a look.
Anyway, cheers mate. Good times to you.
