Endwalker's story had me, but lost me. Ethical issues especially (spoilers)

[Anonymoose]

It feels like I visited Elpis, and my character thought "Gee, you guys sure have a nightmare coming, sure glad it's not my world" as if she didn't care.

I don't know what I believe was on Moose's mind there, lol. In my mind I was ready for shenanigans because if we just needed to see the past, we didn't need to go. This could have been an Echo. Something was up. But Moose? Was was he thinking? I guess, first off, "What the eff, man, Elidibus said I'd be incognito."

But one of the illusions of time from a 3D perspective is that there is a "now" or that anything "didn't happen yet" or "already happened". It's all happening at the same time from a 4D perspective, which means we all need to subjectively experience our role in it for it to stay real otherwise that all vanishes and a new "way it always was" comes into being. Shadowbringers undermined that by using the Rift. G'raha even says outloud, "I still exist. Weird." lol. And yet for some reason Endwalker appears to buy back into Alexander whereby Hydaelyn sets things in motion by sending her champion to Elpis to do the things that already happened to ensure Emet-Selch and Hythlodaeus prop up her edits in Ultima Thule.

Emet-Selch even calls himself, in one language, "the keystone holding this all together and ensuring it works," and that he can't figure out if Hydaelyn is punishing him or offering him an olive branch by giving him the role of delivering the final message from their people.
