FFXIV Endwalker MSQ 70-Words Without Sound

I am curious as to how much we told Hermes. It doesn't seem like we reveal his part in the second set of final days. It seems like we only give the basics: final days, sundering, unknown root cause, dynamis plays a part. That is what I get out of this.

I can understand why we tell Hades/Hythlo/Venat far more details. The bond is undeniable between these characters, and I don't mean romantic, that is just wishful thinking with a particular white haired snarky man. We know exactly who we were in their time period and what Hades and Hythlo meant/mean to us. And Venat well even with our choice at the beginning of EW and her honesty issues we still have a measure of trust in her.

I am typing out my understanding/thoughts here. Feel free to correct me if I missed some dialogue somewhere or misunderstood something.

So Aether essentially protects a person from dynamis but also in turn makes it so, densely aetheric people cannot manipulate dynamis as well. So no manipulation either way. So since the song of oblivion (which seems to be the little devil on your shoulder whispering for you to give into despair)couldn’t corrupt the ancient people it corrupted their magicks somehow.

We know Zodiark saved the star by placing essentially a blanket of aether around the planet keeping the dynamis from even getting in. So that is gone now. Dynamis can get back in again.

We know the sundered have less aether. All sundered minus WoL and G”raha have about 57% of their original soul. (Base/Source+7 rejoinings) We have slightly more. So we can be manipulated by it and manipulate it as well if we wanted to. He says dynamis has transformative potential.

So it seems the source (Meteia) of the negative emotions can only latch on to the darkness that lies in every man’s soul. But that negativity needs to be heavily present within the person to manifest into the blasphemies? So the negativity has to be strong in the individual to hear the sources call (Meteia) to oblivion is what I am getting out of this.

Or like our characters' experiences do people just hear and feel all that pain and suffering that is being projected upon them that they buckle under the pressure and become the blasphemies? Like a billion voices of despair and pain coming at you all at once. But it still seems to be based on individuals' current outlook on life as well because otherwise everyone would have turned almost immediately. And the examples we were given were all people struggling with their current lot in life.

There is so much information given in this quest and it looks like at least Venat is coming to the correct conclusion. Not sure about the others.
