The Reasoning behind The Sundering? (*6.0 Endwalker Spoilers*)

[Cleretic]

And how many ancients did you hear that from? One.

Actually, we heard from... rather a few of them. And by my count, the ones that didn't want to come back, or at least seemed to make peace with the fact that wasn't happening...

• Emet-Selch
• Mitron
• Loghrif (sort of, that one's complicated)
• Elidibus
• Fandaniel (in all identities)
• Hythlodaeus
• Most unnamed Zodiark sacrifices
• Venat

Meanwhile, the ones that either did want to come back, or died mad enough that they're presumably not done...

• Lahabrea
• Igeyorhm, maybe, we didn't exactly give her time to contemplate it
• A minority of the Zodiark sacrifices

Granted, the list is biased towards those who lived through the Sundering and the millennia afterwards, and so were probably a bit tired. But I can find very few Ancients that weren't fairly accepting of their deaths, albeit in extreme circumstances.

Considering that discontent souls are known to be capable of manifesting aetherial phenomena like ghosts, I can't help but wonder if having all those powerful, but grief-stricken Ancient souls trying to go through the Lifestream wringer simultaneously isn't going to cause problems.

...now that you mention it, that might be a problem. Again, most of Zodiark's sacrifices seemed pretty okay with their lot, but even those guys seemed to have some heavy thoughts about what all was going on; there was a lot of 'we did everything right, why didn't it work' anxiety. That's probably gonna hurt even more now that Zodiark is actually gone rather than just in trouble.
