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.
