Wait, so does that means that we could change the past if we want ?
Let's say that we completed the loop, met Hydaelyn and saved the world from the Endsinger.
Could we return to Amaurot in Elpis time, and tell Emet Selch what we knew again ? Or for the sake of arguing, kill Argos ?

Would this be impossible considering we are on a loop/convergence of time after the Elpis arc ?
Because the way i see it, nothing prevent us from changing the past in more significant ways now that we got the results we wanted.

We could actively try to change the Elpis past with our post Endsinger knowledge by doing things we know didn't happen at the time. But if we did (or would be doing later technically), then the timeline wouldn't be the same...
This is breaking my mind...

Nope. That almost definitely wouldn't have worked. FFXIV time travel generally has two results:

A: Time loop, where you set in motion the events that ultimately led to you going back in time to set those events in motion in the first place. Seen in Alexander (on two different scales), and in Endwalker.

B: You create a new timeline and orphan the old; the old timeline still exists and progresses, but is no longer The Future. Seen with G'raha's timeline, and observed by, of all people, Seigetsu the Enlightened. That's right, the Namazu matter.

There is no clear explanation for exactly what leads to either result happening, all we know is instances in which they happened. But those are the possibilities, then you can't fix the future by going back to Elpis and changing the past, because what would actually happen is either that you'd either be stranded in Elpis and nobody in the present day would ever know or be able to do anything in response, or find out that you already tried this and that all your attempt to change the future does is set up the scenario in which you went back to change the future.

I see, this clarify things, thank you. I'm really eager to see how the third tier of Pandaemoniun will handle our shenanigans with time travel.
Technically it should be fine since our actions will only contribute to the timeloop if i understood correctly, but we never know.

The concept of temporal magicks is vague enough that for all we know, we could've already spawned alternate timelines and getting stranded as a result of such is simply impossible due to us being so firmly rooted to the two points we're bouncing between that relative time is still able to pass in both past and present and also ensures we always return to our original timeline.

Though that's just me hoping Pandaemonium manages to retroactively give Elidibus and company a happier ending in a different timeline that we learn about somehow instead of simply twisting the knife.

It should also be noted that right now, Pandaemonium looks like it might be performing the only known instance of something going forward in time rather than back (or 'forward but to native time period'), so we have even less of an idea of the ruleset for that.

Or it could not be doing time travel at all and have gotten there by an entirely different method of transit that's just not known to us right now. Personally, my suspicion is that it got dunked into and travelled through the lifestream in the same manner as the crystal that started all this.

Given the first Pandaemonium quest involves the WoL going back to Elpis by attuning the Occular's portal with the memory crystal that the Sharlayans found in the Aitiascope, and that they then walk into the portal in the same way they did the first time they went back in time to Elpis, it seems that it was working the same way as the first time (using G'raha's dimensional transportation magic and the time/space machinery of the Crystal Tower), and that Elidibus's time portal is still active, it just needed a new 'destination' attuned to it (which was attained by the crystal).

Why the WoL then materialized in the sky above Elpis as a shooting star that fell onto the hapless Themis is anyone's guess though. ;)

The moment you include the timeline as an actual thing, you can no longer be certain if it is a loop or just a new timeline, nobody can guarantee we arent now on a new timeline and the one where we left still exists but with the WoL disappearing forever, not only that but with timelines being a thing the possibilities are literally infinite as to what can happen and how many exist.

By that logic as well we can have invaders from other timelines since in a sense, Graha came from a different timeline, what stops other timelines from doing the same considering there's infinite possibilities and Graha wont be the only person to achieve time travel in said infinite timelines.

Like that is the problem when you decide to go both ways, I guess it can be interesting since you can have a garlemald victory timeline and finally give us a decent garlemand empire but it doesnt change the fact it is quite a bit silly when you open that can of worms and makes the story have less weight since anything can just be explained as a new timeline when you time travel like this.

The nice part of the time travel being here is that it immediately solves the heat death of the universe problem. Just travel back in time with your population and start a new timeline. Rinse repeat for infinity

Technically time should be able to branch off, so yes we could in theory do this. Dunno if the connection between our current timeline and that branching timeline would be able to survive the process. If we did that, in theory we might be stuck there. (I mean it wouldn’t happen in practice cus video game, but you know.)

I want to help those people and consider our inability to avert the final days an epic fail on our parts so I’m all for trying this. lol Then again I also want an Unsundered World expansion and to see the real Amaurot, so.

Yeah i imagine the possibility of getting trapped is a big reason of us not actively trying to help the ancients (and the fact we could make things worse so it's better follow Venat's plan).

But like you i want to help these people. I feel really bad returning to their timeline for Pandaemonium while i know they are doomed. Feels like we're leaving them to die now that we got what we needed.
