(Spoiler) About amaurots downfall

[Iscah]

He must have done something similar while on the Source, which is why he would be the only known Ascian to have offspring (and probably not in the conventional way).

I don't see why he wouldn't have had children "in the conventional way" - he's possessing a human body after all - and it still grew and aged and died like a normal human. They would technically be Solus's children, not Emet-Selch's.

Which doesn't rule out him doing something to a naturally-born Zenos (or previous generations) like he did to Vauthry, of course...

so i have a question do you remember back to 2.0 end cutscenes where it showed for a few seconds a dark looking aspected mother crystal i took that to represent zodiark but why are ascians trying to wake zodiark did that scence not imply he was already awake?

[ObsidianFire]

Zoidark is Sundered the same way the Shards are. The point of Rejoining the Shards to the Source is to put Zoidark back together at full power and then sacrifice all the life on the Rejoined Source to him to get the Ascian souls in Zoidark back.

What is interesting about the vision we have of Zoidark in 2.0 is that it's not just something we, the player, see. It's an Echo vision the WoL gets. The purple crystal is confirmed to be Zoidark in 4.5 when it's the backdrop to Gaius' info drop to the WoL on the known Ascians.

People seem determined to follow this "the Ancients were the cause of the first apocalypse" mentality despite what little evidence we currently have seeming to suggest the exact opposite.

I think part of that comes from the Amaurot dungeon, specifically when you finish fighting the Terminus Bellwether and port to the platforms above the star. The area you immediately walk into speaks of the "sins" of the ancient Ascian's come to life. The word "sin" implies some kind of transgression was committed, and informs my earlier suggestion of "soft hubris" as being at least partially responsible for the catastrophe.
Still not quite fair to "blame" the Ascian's for what happened. Even if - as Cilia mentioned - there was some kind of creation/destruction imbalance at play, with the pendulum swinging hard and fast back towards destruction, we have no information to suggest that the creation-imbalanced state of the world was the intent of the ancients. Regardless of all that though, I'm still of the mind that the "sins" Emet spoke of carry a strong sense of implied responsibility, even if the Ascian's weren't aware that they were committing such sins in the first place.

Please tell me I'm not the only one to immediately think of Lavos.

Oh fug. That would certainly be a thing. Not necessarily Lavos per se, but a being in a similar vein. Middy and Omega could travel between stars. Great distances too. It stands to reason that other beings could as well. It would certainly scratch my giant space flea itch.

I very much hope this turns out to the be case. Having something to explain Zenos's insane strength other than "because reasons" would be great.

Hmm I wonder what happened with the source of the sound?
I think it was only said that zodiark fixed the chain reaction the sound caused but not the source of it itself, correct me If I am wrong.
If zodiark didn't destroy it ,then its really bad cause it would either have been split up too or its on another shard.

Rampant speculation but...

It could have something to do with what's in Silvertear Lake.

We don't know for certain exactly what Zodiark did. If we take Emet-Selch's description of events as truth, then its initial summoning entailed rewriting the very laws of reality to both correct the initial problem and rid the world of further damage done to it by the Ancients' runaway powers. The second summoning (or re-empowerment, depending) was used to restore the world's ability to sustain life as well as possibly creating some new lifeforms to inhabit it.

[Cilia]

It was said that Zodiark "rewrote the laws of the star," and that in so doing was able to stop the Sound. It's still unclear what caused it; the only thing really known about the Sound is that its effects were originally localized, small-scale disruptions. When it reached Amaurot it... basically caused the Apocalypse. (Literally. The bosses are identified as "Beasts," as in Beast of Revelation, and the final boss "Therion" uses one of the names attributed to said Beast.)

One thing that worries me with the new info from Shadowbringers is Lahabrea's pre-battle dialogue in the Praetorium, though.

The growing imbalance afflicting the planet must be redressed. If it is permitted to worsen, the very laws of existence - both aetheric and physical - will be warped beyond all recognition. Know you the root of this corruption? Hydaelyn! Like a parasite, she must be burned out if the planet is to recover. And naught but the return of the one true god will ensure her complete excision.

Now, I might be crazy, but to me it sounds like he's suggesting that without Zodiark's return the Sound might come back. (Granted this is coming from an Ascian and was written like, what, five, six years ago... but even so...)

[Alleluia]

If we go with what they've revealed now, it almost sounds like Hydaelyn is being equated to that sound.

But like you said this was written years ago, supposedly before the specifics from ShB were ironed out. Also, even if that is what Lahabrea was aiming at, its a pov influenced heavily by bias towards Zodiark. ie He could be wrong or being manipulated into believing a lie.
