The Reasoning behind The Sundering? (*6.0 Endwalker Spoilers*)

[Cleretic]

Actually, I think that of all zones in the game, the Thavnair revisit is the one where the WoL is the least influential on the eventual positive result. All we really did was kill the Blasphemy (even then not solo), which didn't exactly do a whole lot in the short term. The real contributors to overcoming the End of Days--which is much more a psychological battle than anything--are Vrtra, Ahewann, Matsya and Estinien. And Estinien was mostly just Vrtra's moral support.

There's a good few zones and side stories where the story can essentially boil down to 'it's a good thing Superman turned up', but the Thavnair revisit is perhaps the one that has that going on the least, we're mostly just seeing Thavnair handle itself. Hell, we don't even get full credit for the baby save, that's a three to five person job depending on if you give the twins an assist credit. I think Y'shtola has more influence on the story in that stretch than we do, and her contribution is 'being blind'.

And Vrtra is hardly an external factor in Thavnair. He's a Thavnairian citizen as much as anyone else, and doesn't actually contribute by way of 'being a dragon', he contributes by way of being a trusted leader who steps up when he needs to.
