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

[Dikatis]

Y'shtola credits Hydaelyn with having forestalled the Final Days after she knows better from the moon.

This is straight up false. Here is what Y'shtola says:

By sundering the world into fourteen shards, the aether of all living beings too was divided. This reduction would in theory allow us to more easily interact with dynamis. Having seen mankind brought to the very precipice of extinction, you wished for us to develop a means to overcome despair. You believed we had the potential, and sundered all creation to see it fulfilled. To deliver us to that swirling maelstrom of dynamis in which our foe hides, and grant us the power to defeat her once and for all. Is this not true?

[Rulakir]

This is straight up false. Here is what Y'shtola says:

Your move.

[KariTheFox]

Your move.

That quote is from At World's End, which is before the visit to Elpis. Y'shtola had an innacruate understanding of the situation, and then after you visited Elpis she had a different understanding based on what you told her.

This isn't a contradiction, you're just being dishonest.
