Revelations from Patch 5.2

[Alleo]

So, about the WoL's nature and 5.2:

I get that seeing a star shower-esque thing is supposed to act as a power trigger for those with ancient soul fragments and it makes them able to hear Hydaelyn. But I've rewatched the opening scene of ARR multiple times to be sure and we hear Hydaelyn's voice in our "dream" without a star shower having occurred. We don't see a star shower til we get our first crystal (and then we immediately see Hydaelyn herself). So... that's interesting?

About your points

Well we also have to remember that this was Elidibus doing. I am not sure if we can trust him on anything. Urianger even states that he lies if it further his goals. Honestly I am not even sure if that was Hydealyns voice at all. It sounded so far away so strange. I wonder if maybe some people are just born with active echos? Seemingly Zenos has dreamed about a destroyed world for a long time, maybe we too already had the echo for quite a bit.

Hydealyn only talking to us directly after getting our first crystal makes imo more sense than her just somehow turning people into WoLs if they get the echo. We had to prove that we are able to be WoLs by getting a crystal (just like Ardbert and his friends) so I doubt that those people are all just WoLs.

Regarding Elidibus's plans:

Am I the only one who thinks its possible Elidibus' gambit is going to work? Just, story-wise, it makes sense for him to have some kind of victory leading into 6.0. And it'd be weird for the plot to end up being "Lohgriff attempted a flood of light; it was thwarted by Minfilia. Emet-selch attempted a flood of light; it was thwarted by WoL. Elidibus attempted a flood of light; it was thwarted by WoL." Like, either succeed this time or stop proving the definition of insanity.

The problem with that is that a flood of light would destroy everything we have worked for. And would make no sense gameplay wise because we do need to be able to visit the first. I also believe that it would be way too dark for this story. Everyone we have known, every beast tribe we have helped, all the stuff with Eden or Nier would be gone. And Elidibus also needs a desaster on the source first otherwise a rejoining wont happen.

What should realistically happen on the source that will be calamity level? Black rose is something Zenos does not want to use, normal war wont bring a calamity of light. So I doubt that his plan will work.

I think that us being more active and going to them will stop it. Or maybe (since he does not like us) he underestimated the new "WoLs" believing them to betray us..
