What's the point with that quite lackluster story in Endwalker?

[Cutes]

Side tangent—if Hermes was memory wiped and willing to help the Ancients from the seat of Fandaniel, he should have still known about his Meteions, unless he had come up with the concept during his lunch break while we were in Elpis and sent out a few thousand in that time alone. Additionally, as an expert in Dynamis, he probably could have, should have, would have been able to do something about the Endsong if he were sincerely trying to help. The story even explicitly states that he and Venat were the ones to deduce that the aetherically-weaker portions of Etheirys' atmosphere were what the Endsong 'broke through' to affect the Ancients, yet Hermes could neither identify it nor come up with a solution. This has the added benefit of making the Venat situation so much worse morally speaking , since she knows the Metia are singing the song of oblivion and knows about Dynamis, yet still says nothing and simply allows the Final Days to happen. Geez, there are really too many side-tangents to choose from when talking about Endwalker, doesn't that speak volumes about the quality of the story?

Ultimately the time loop causes all of this and ruins everything, especially Venat's character, because she must remain silent despite everything and have all agency stripped from her character in order to propagate causality. The WoL has no agency, because they must travel back in time to set the wheels in motion. Never endingly, with no true freedom of choice in sight: all roads lead to the time loop.

While the game only explicitly states Hermes as the seat of Fandaniel deduced the cause of the localization of the Final Days was stagnant celestial aether (mentioned by Elidibus before we travel to Elpis), Venat didn’t work with him as far as I know. We learn during our time in Elpis that Venat does already have some knowledge of dynamis. She learns the true nature of Meteion and the song of oblivion and she has foreknowledge of the Final Days thanks to us telling her and her not having her memory wiped. Venat is not foolish and could put together the cause of the Final Days but does not impart this knowledge to anyone during that calamity in favor of relinquishing her agency for the causality loop. She even says herself she must have had a reason to take such measures, but is deference to a predetermined outcome truly so compelling? It’s morally troubling given the tremendous loss of life that followed it.
