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

[KageTokage]

The only one who knew about Dynamis, much less use it, was Hermes, which is a terrible warning as he ended up doing a "universe"-ending mistake as he didn't realize how strong Dynamis can be.

And it is irrelevant since if he knew what was really going on, he would try to sabotage any attempt to stop Meteion as he did before the memory wipe.

And "surely they would think of something" is meaningless, unless you have a specific example to give.


And finally even if they somehow managed to stop Meteion, we (and Venat) knows they were bound to be destroyed either by misuse of their power or by losing the will to live like all other civilisations.

The problem is that Elidibus admits that the Convocation's understanding of the Final Days "was the same as our own", which means that whatever information Hermes provided to them was...non-essential. He wasn't even able to pin down dynamis as its cause.

He is not going to be sabotaging anything if the Convocation was aware of his behavior, and they were apparently already accounting for dissidents like him considering that they had a bureau of justice (Which Emet-Selch actually mentions that he might have to get involved when he first hears about Kairos due to recognizing the potential threat it posed).

And yes, they may have hypothetically run into/created other threats that would've ended them, but by all accounts, they had already kept things together for a long, long time, and considering how easily both the Nibirun and Ea were convinced that life was still worth living by the end of the Omicron quests...I don't think a race of intellectuals like them is ever going to collectively agree that erasing themselves from existence is the best course of action.
