Yes, but the blessing is built up over time as we gather those crystals. So all the other people with The Echo might not necessarily have built up the blessing. There isn't necessarily a confirmation that they did.
Like in real life, we can say things are bad for our health, but usually the consequences won't be felt until we're much older. Unless we travel into the future, we probably won't meet old Y'shtola.
I saw that as just his imagination/memory. We enter Cid's memories later on in the Bozja story and there are things that happen there where at first it's wrong and then has to be corrected, to demonstrate how memories get mixed up.
I saw handing the goggles back as a symbolic thing of "here's your memories back" and that this fact was making its way into his memories when he probably got them some other way.
Still, it's not impossible time travel was involved. We don't necessarily know a lot about it. We just know that Alexander can do it and therefore primals can do it but maybe we will learn the inner workings of it in future expansions.
Not true. They had a pretty rough idea of what they were doing the whole time. The entire plot through Heavensward into Endwalker is foreshadowed in a Heavensward cutscene https://youtu.be/hJZ94R0TEzE?t=147
The cutscene says that Zodiark coveted power, so Hydaelyn bound him to the Moon. She admits she sundered the star into 13 reflections, each possessed of a shard, which I assume means the elemental shards we see her use so often. She tells us that the Ascians' goal is to restore Zodiark and make him whole (which is true) and that they are His servants (also true because Emet admits there was no fighting the tempering of such a powerful primal). She tells us they mean to tear down the barriers which surround the Source by creating calamities that result in a Rejoining that will help rejoin, among other things, Zodiark's fragments. She tells us they succeeded 7 times (also true).
If you go back to ARR you can even see that a lot of what Lahabrea says at the Praetorium is true, vague as it is. They obviously didn't know what they were doing then entirely, but they had a vague idea that their goal was to restore their god, Zodiark, by way of calamities. Which remained true to the end.
I think it can be argued that we defeated them in the Summoner quests, taken care of by Shadow Hunter or while chasing Elidibus.They also forgot that Black Mask Ascians exist after HW, not quite a retcon but generally a plot point that youd think would get more attention in light of revelations from ShB, but nope.
Yes, that was clearly a retcon because the fire was obviously meant to kill him. In fact, if you run the video of his final moments in slow motion, the flame intensity increases significantly making it impossible to leave the flame circle and then there are unavoidable explosions everywhere with him still there. The only way to argue he lived would be to say that what the cutscene showed us wasn't accurate and that he in fact ran out of the flame area right before the intensity increased.Gaius surviving was definitely a retcon and not something planned though.
Arguments have been made that him not being in POTD showed they were not sure about saying he's dead even as early as Heavensward. I'm glad that they didn't kill him because I found myself mostly agreeing with what he was saying and wondering why we were even enemies, when he was mostly being manipulated by Ascians and misguided by having grown up in the Garlean Empire.
It sorta comes back at The Tempest. The gibberish language still rings clear in our minds like it does with the dragons. When we go through Endwalker, they just use English, probably so that it doesn't annoy us, but it's the same everywhere, you know? We're going to Tural and they probably wouldn't speak our language. In fact they admitted they don't in the latest patch. Yet, we're going to go there and we'll all speak English, because the story wouldn't be fun if we needed a translator.
I never took that to mean it was actually Zodiark's power. I took it to mean it was an example of what his god would be able to do when it was restored, but wasn't actually being cast by his god. It's like if I open MS paint and draw a picture of Zodiark destroying everything. It's not actually Zodiark's power, it is just a picture; a demonstration of what Zodiark's power level will be when he is restored.During the first cast, Lahabrea claims that "this is but a test of my god's power"
