Spoilers obviously, ran out of room in the title.

So I keep seeing the mentioned 'you'll go THAT far..' quote by Yoshida around the forums, in various usages. (Things introduced, added, possible links, people saying that was the time travel and space.)
The issue is there was MORE to that quote than just that part. It was specified-- quoted from the article that translated it."There is a big mystery that will be revealed within the saga of the "Hydealyn versus Zodiark Arc. For those of you who have come along through the journey of FFXIV up until now, you might think "you'll go THAT far...?"Once this mystery is made clear, it shall then form as the basis of the new chapter of the story. In lieu of that, we have pourer our thoughts from these past 11 years and have also put preparation into the content moving forward for the next 10 years to come."
Key points to take away "revealed WITHIN the saga" "big mystery" and much later in the interview that the mystery will lead into the next chapter of the story.
So... to those fellow players who have finished. What mystery was revealed that could possibly play into the next chapter?
Possible Contenders:
Zenos: Yes, I know, groan all you want for those who don't want to see him. But the fact of the matter is, Yoshida goes very mysterious when talking about him or hinting him, he was known as one of the big players for Endwalker despite the small role and HE IS ON THE POSTER WITH 'all of the scions'. It is possible with Alisaie's speech, his last defeat, and question he asked that was never answered before his 'death' (if it was one), that they are setting him up for a smaller redemption arc or lead in to the next part of the story. The mystery being why he is the way he is as he said he doesn't even know.
Universal Races: Side quest and side dungeon leads you into telling an Omicron his next goal in life should be to simulate and archive the various races. So far you have ONE in Nekropolis, with a list that looks like it could grow. It's speculated this will be beast tribe or trials, but it can also be a 'mystery.'
Emet: He told you many places to go, but they're not huge mysteries and not revealed within the whole saga, just thrown in at the end. Except for Corvos, which G'raha mentioned a bunch and many others. Corvos may be a mystery.
Missing Dragon: Vtra's sister who he said was 'silent as always.' His thing with Estinien might be with that, but again this was thrown at the end not really a mystery revealed throughout.
What happened to the Universe?: Not too sure on this one, but other than Meteion helping a few races to keel off, before she went out, what happened to the Universe, not every race of every star for gazillions of eons could have chose nihilism, or been destroyed by the Omicrons, maybe there was a standing cause before. Though I'd hate that as then we'd be going the route of DBZ.
Can anyone think of any other mysteries that were revealed, that would have heavy implication for him to say that? Note it also said saga not just Endwalker, so was there any GLARINGLY giant mysteries that need to still be answered that would make a whole 10 more years? (As much as I want to know the Sabik thing, don't mention it, too small scale.)
