*Spoilers* The Past and After the Endwalker MSQ End

[EaraGrace]

1 and 2 are already done. We can teleport to Elpis at a specific point in time - where people acknowledge us as Azem's familiar. There doesn't need to be a complex rationale behind it. Some weird timely wimy thing has us linked to this particular Elpis in space and time. Do recall that the First wasn't always temporally balanced with the Source. The other Scions spent years in the First whereas only a few months have past on the Source when you went back.

Issues remain, the door to Elpis limits us to a very specific period of time, and you’d still have the issues I mentioned if you don’t attempt to replicate those magicks.

The rest will depend on SE writing the plot. The quickest way is to just have the Convocation use the Echo on you. The Ancients also have ways to determine if your lying.

Exactly how effective the echo is with finding specific memories is difficult to say. Ultimately, the problem is that even if you convince them, you still have Hermes sabotage to deal with, and given he isn’t there to help with Zodiark now, it’s unlikely you’ll succeed at forestalling the first final days. It was SE who wrote that limitation.

Venat judged that many would fall to despair when faced with 'reality', but that's also her own presumption. That's an assumption Vauthy made of people of the First as well, but we've seen how that turned out. In this expansion, Vrtra was convinced (based off his eons of experience) that everyone would hate him, but it didn't turn out that way either. As is noted in the story, Venat as flawed as much as everyone else.

And yet we are shown why we should believe her judgement the correct one, if their reaction to the Final Days is indicative.
