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

[Teraq]

This thread is a metaphor for the storyline, because it's just going in circles, achieving a time loop of despair roughly every X week.

Can I blame it on Dynamis?

(Dynamis and Meteion)

I don't think any one here ever even implied Ancients themselves could just waltz into Ultima Thule. That is, after all, the single consistant rule of this game of Calvinball: Ancients can't play because we needed at least one reason to justify Venat's genocide.
