Thank you to whoever wrote the Pandaemonium story so far [SPOILERS]

I find this sort of reaction amusing considering the Ascian history of destroying all life on entire shards simply because they didn't consider it life and therefore wasn't murder.

Also curious to hear how you think the WoL could have saved Ancient society all by him/herself. By the time the problem was known, it was beyond the WoL's ability to handle solo and the Ancients couldn't interact with Dynamis.

Again with the conflation of the innocent Ancients with the Ascians only three of them eventually became under extreme duress? They were only driven to these acts because of the situation they were put in by Venat. Which she had 100% intended, by the way, as she was literally responsible for the Unsundered's existence to close the time loop, which she knew involved 7 rejoinings by the time we would meet her. Hence, Venat shares culpability for destroying all life on entire shards – along with, of course, outright committing genocide on her own in the first place.

The poster doesn't say anything about the WoL saving Ancient society all by him/herself, because that isn't necessary. Ancients may not have been able to directly interact with Dynamis as they were, but:
1. They could literally create Dynamis-capable creatures as evidenced by Meteion. "BUT ONLY HERMES––" no. We are told Hermes is not the only person who knows about Dynamis ever. The Elpis flower exists and is there for everyone to iterate upon. Give Ancients motivation to research Dynamis, such as… oh, I don't know, ACTUALLY TELLING THEM THE DYNAMIS APOCALYPSE IS COMING!!, and there is no reason why research couldn't have been kickstarted.
2. They can't interact with Dynamis because they're too Aether dense? Then let's consider:
a. diminishing their own Aether as the forcefield within Ktisis Hyperboreia does
b. manually sundering their own Aether like Lahabrea just did – which we now know they viewed as unprecedented and highly risky, but again, when it's to counter the literal end of the world, I'm sure mavericks like Azem would try something like that if it meant saving the planet.
3. They would have had time to do all this, because with Venat telling the Convocation that the solution was reinforcing celestial aether (as we literally told her that – therefore Hermes's sole contribution was unnecessary), they could have come up with a way to do so without being taken by surprise by the Final Days and resorting to the extreme of summoning Zodiark. Given that Zodiark was able to repel Meteion's song for 12,000 years while literally dismembered, broken across 14 dimensions and in a coma, I'm thinking it couldn't have been that hard – because Dynamis is hilariously weak against Aether.

But yes. I know. "Ancients couldn't Dynamis!!!!" is the reason given by the game, straight out of Author Mouthpiece Y'shtola's mouth, confirmed by Hydaelyn. Whose justifications for not telling anyone that mattered of the Final Days in the first place is a pile-up of suppositions about how people would react – and never actual facts. Anyway, not my fault Endwalker's plot is shoddy. There's another, nearly 700 page thread about this.
