Inconsistencies with the sundering (Spoilers)

[Aniya_Estlihn]

I brought this up earlier and someone said that it still makes sense because blasphemies still appear even after the endsinger died, and that sin eaters still exist on the first.

There are inconsistencies, but when media released after Endwalker continues to affirm what was established before 6.0 as canon, you really don't have a leg to stand upon. I'm encouraging you to quit looking so deep into what is clearly just a poorly directed scene that is placed in a portion of the story where it doesn't belong.

People expected a 1-for-1 retelling of the Final Days and Sundering; I did too but accepted that they wanted to go with the vague nonsense metaphorical bs as Ishikawa has done many times, and instead got an intellectual experiment of a scene with little to no narrative value and now said people; e.g. you, are grasping at straws and trying to affirm their delusional interpretation by asserting that a nonsensical, symbolic scene with no value to the narrative has anymore value than being a nonsensical, symbolic scene.

Even your examples of these so-called inconsistencies make no sense:

Terminus Beasts appear because the role quests canonically take place at the time they are introduced in the MSQ, as does every quest that exists in the game. They also still remain from those who turned, which like in the First, the entire world was afflicted—that's potentially millions who fell to despair and turned into Terminus beast and they aren't just going to "go away."

Likewise, Sin Eaters exist on the First because while we ended the Everlasting Light, there is an entire world that was swallowed by a flood of a light wherein all the inhabitants were turned—human and beast alike. Norvrandt has a few eaters remaining, but the Empty; aka the entire world outside of it, is still a bleached wasteland that will take centuries to be restored and Sin Eaters will be as plentiful as there was life in the First.

This means that despite the fact we go to Norvrandt: the First's Eorzea, the First's Gyr Abania, Othard, Ilsabard, Thavnair, Meracydia, The New World, Sharlayan and variant of everything else we know on the source had all the inhabitants turned by the flood. Said lands are likely still teeming with sin eaters and will be for a lo ng time. Ending the flood doesn't stop their existence.

It is poor writing, but not in the way you think and continue to assert it is.

You don't like the writing in Endwalker, that's fine, I don't either, but asserting utter nonsense to try and criticize their poor decisions and use of metaphorical storytelling is just... well, its silly. You are genuinely making no sense.
