Demons, Heaven, Hell and parallel universes

[Cleretic]

Okay I'm confused here...
First someone wonders why I bring up a multiverse and then goes on to say that there are multiple universes... which is exactly what a multiverse is.
Then I'm suddenly wanting there to be demons and am focussing on demons, when I mentioned them once in one out of five paragraphs.

Where do you gues pull those interpretations from?

They are literally the very first word in your thread title, and take up a weird amount of your original post for not being your actual focus. If they weren't something you're asking about, you maybe should've done an edit pass on your original post.

But okay, let's talk alternate universes:

Yes, there's a multiverse, but it's eminently quantifiable. On a cosmologically close scale to the Source, we have the shards; somewhere further out than that, we have a multiverse covered by other Final Fantasies, including Dissidia. There is not a universe out there where up is down and cats is dogs (unless FFXVII gets real weird), but there is a universe where Quina exists. Spinoffs and side games also exist in this space, going by Ace being in Dissidia NT, so it's not completely out of the picture for a FFXIV character to turn up in the universe of Mystic Quest, if for some reason someone wanted that. The hiccup here is, of all things, the Dragon Quest collab, which implies that somewhere in this multiverse is a world with the Brickmen, but it's kinda hard to read that as signs for the future. It might not be that hard, though; it makes complete sense that a Dragon Quest world is somewhere in a weird corner of the FF multiverse.

And yes, it's possible to travel to the past of a shard, including to one that doesn't exist; this happened in the main story, this is how the Crystal Tower got to the First. However, this is not only extremely difficult--time travel and shard travel are fundamentally different systems, so you basically need to get two different machines to work together for it, as explained in the Twinning--it's also a phenomenally bad idea in 99% of cases, as to put short, it's in no way worth it unless the world you're escaping and probably never getting back to is doomed.

And yes, as Porxies points out, it's an absurdly unlikely thing to happen for the sake of an event as most of these are, because the events are set up in ARR zones so as many players as possible can participate.

To my knowledge there's nothing about cats and dogs, but there are the moogles in FF8 and 12. In the former they start out as giant mole-people and evolve into cute and cuddly things that look a little werewolf-ish. And in FF12 they are winged bunnies instead of the winged teddy bears they are in most FF games.

Oh right... G'Raha and the ironworks did send the tower back, after the 8th calamity, which would have consumed the First. Somehow I never made that connection. Good point.

As for the difficulty of time and rift travel... that certainly used to be true, but between Electrope, Azem's key, the gate to the Golden City and the Alexandrians being able to do a localized "mini-rejoining," which I for one would have considered entirely impossible before Dawntrail, there are definitely new possibilities now.

Speaking of the realm fusuion... I wonder if that could be used as a way to do a full rejoining, but without the massive casualties that the Ascian way entails, by doing it in many small steps. Imagine if you could merge a part of the First into some uninhabited desert on the Source, then evacutate the people brought over into the Source, and do it again in the same spot, rinse and repeat until all parts of the First have been brought over, or at least all sentient beings at any rate. Well... the First might be a bad example, since it is in recovery, but if there's a reflection that's about to collapse, and become another horror show like the Void, this could be done to evacuate the survivors into the Source.

So did you notice that this technique was only ever framed as, and used as, a tool for invasion and conquest? That there was no possible 'positive' use of this ability, because it was always being used to enforce one world's existence over another?

Maybe think about that fact before deciding that you could totally use it to do a 'good Rejoining' by displacing the entire population of a planet. And for what? At best this is a hyper-specific evacuation plan... that would actually only serve to mangle the Source as you start doing these cut-rate micro-rejoinings; notice that Heritage Found is really terrible ecologically. That escape plan also gives up on a hope for recovery that I think is pretty core to FFXIV's outlook: that things can be made better.

And instead trying to approach it as a Rejoining itself is actually worse; nobody wants a Rejoining. The only people who were ever pushing for that were a bunch of nostalgic ghost wizards that are all dead now. And even their approach doesn't work here; even if you do buy into 'more soul equals more better', a Rejoining that somehow doesn't kill anyone wouldn't even do that, because then no souls are being rejoined.


In short: Bad idea.
