(6.X Spoilers/Theory) Future WOL Content - Everything’s Coming Up…

[Rulakir]

Emet revealed that the remaining inhabitants of Source who survive the rejoinings would be sacrificed to Zodiark to bring back their loved ones, the previously sacrificed. I reckon those souls would come back in the form they were sacrificed in and would hold their memories, otherwise the ascian plot makes zero sense. I presume this would mean that those who survive all the rejoinings wouldn't suddenly become the unsundered ancients they once were, and in addition all the souls reborn in the rejoined world wouldn't be any more closer to being the ancients they were pre-sundering, aside from being as powerful, intelligent and long-lived as they once were. Emet's plan on sacrificing the lives of the Source wouldn't make much sense if those fully rejoined became the ancients they were, especially since Emet must have known that Azem, his supposed great friend, is somewhere out there.

Emet also tells the WoL at the Lift that if they survive the calamities they will become their equal, a complete being in a complete world. Their goal was to make things whole again, which is why I never bought into the interpretation that he meant to sacrifice the sundered on the Source. I can see how some arrived at that impression, but it doesn't make sense given their objective. EW further threw a wrench into that by showing that the souls of those sacrificed are trapped within Zodiark, so it'd be counterproductive.

As for remembering their past selves, there are hints of that in ShB. Alisaie in particular says:

"The starshower didn't awaken me to Hydaelyn's voice. But that vision of the Final Days, of Amaurot burning... It filled me with sadness to the very pit of my being. Things I once knew, people I once loved, promises I once made... It felt as though long-forgotten memories were dancing at the edges of my mind. But when I try to focus on them, they simply fade away. An effect of having a fractured soul, I shouldn't doubt."

I personally do not doubt the plan to sacrifice the rejoined Source. Majority of ancients already okay'd the third sacrifice in the pre-sundered world, I don't see how sacrificing the rejoined Source would be any different than the last time. Emet trying to lure us into the idea that the shards need to be rejoined for our benefit as well, and that we can work together peacefully (granted we can control the light), it is all just manipulation to me. But I confess that I am biased when it comes to Emet specifically in ShB, as I believe there is nothing redeemable or humane about him anymore, despite the story making us question his eagerness and conviction, that he might harbor guilt and pain for things he must do. I confess I always believe the worst of ShB Emet lol!

I forgot about that piece of dialogue. I'm not entirely sure how accurate or real those memories are to that one soul in specific, or if the starshowers just generally induced a very strong reaction to the past events that would feel like true memories. But Emet also said that we might have very vague memories of the past, so I'm not sure. Safe to say that we have yet to see any past memories of Azem though, even if we are eight times rejoined.
