What exactly do we know as of 5.3 about the sound that was heard before Amaurot fell?

One thing that I find kind of interesting is that there's no indication that Emet or any of the Convocation had ANY CURIOUSITY AT ALL about what the Sound was, what was causing it, or how to stop it. They're all, "Yup, it all started with the Sound," but from that point on they do nothing but talk about the damage control.

I'm guessing that the whole reason the Dissenters stood against the Convocation is because they had a better understanding of the Sound, and realized that the Convocation's plan was not going to accomplish anything to solve the underlying problem.

The Sound is one of the great remaining mysteries of the Final Days, and I doubt we've heard the last about it.

I doubt it were Venat and her followers who had a better plan. The Convocation was formed of the greatest sages of their kind, and if they did not know, then the dissenters probably did not have more knowledge. Their priority with Hydaelyn was subduing Zodiark, they mention nothing of the Sound. As for the Convocation, I assume they had their hands full on trying to prevent the ongoing catastrophe.

I would say, if anyone might have had any idea about the Sound's origins and the determination to quell it, that would be Azem. It was part of their role as Wanderer, to know the star and any threat to it. If Hydaelyn had meant to be a solution, Azem would have not rejected Venat's invitation to join them. No, I think Azem set out to find the origin of the Terminus, but as we know, whatever they might have uncovered was lost when they were sundered. Yet, who knows. Perhaps the key resides in us and whatever memories of Azem we possibly regain. That would be certainly interesting.
