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

[TaleraRistain]

They all originate from said "civilisations". The chair exists for the very reason that the Convocation wanted to understand what is going on in the broader star to orient its decisions, so that is a bizarre claim. Hades himself had a background as someone who travelled a lot. It's not that the other seat occupants did not necessarily travel, but that that seat (Azem) was dedicated to it for the purpose of providing them information. The other seats all had their own spheres of expertise and responsibilities, like any real government. You're inventing a caricature.

There's no guarantee they had to listen to Azem. They didn't in the island story. Azem went against their decision to save innocent people the Convocation was just going to let die.

"The island had one village upon it, and a wealth of fertile farmland─all of which would soon be lost. But that was simply the way of the world. As in many such cases, our role was merely to acknowledge the fact. The islanders would do the same, and those who deemed it prudent had likely already begun to move elsewhere. While it was true that the Convocation intended to discuss the matter, the conclusion would be no less inevitable."

The Ancients may have held funeral rites and respected deaths but their folly was complacency.

Except as we see when we go to Elpis, even though Hades may not believe us, due to his duty of the star he takes it upon himself to investigate. Not only this but he knows he was mind wiped. It’s as simple as Venat telling him how it happened. Irregardless he would have to investigate, and this isn’t even accounting for the fact she could just simply use the echo to show him. I feel like we’re going in circles with this because people are purposely being oblivious to fairly obvious ways it could’ve been addressed.

I think people are questioning your obvious ways because there are giant holes in current knowledge about what actually happened, who tried what, and who talked to who. We don't know that she didn't talk to someone. Panda implies Azem has some sort of future sight. What if she talked to Azem and Azem said "Uh, no, do what you're doing". Maybe she confided in Elidibus or he got involved after the events of Panda. He certainly wouldn't remember. His memories were fragmented. We know she didn't tell Emet. We don't know exactly why.
