Who knew the 6.15 Omega Quests… (Spoilers)

But speaking of a lack of evidence, Hermes is never accredited with Zodiark's construction. Never. Not one time. If he was at all vital to Zodiark's innerworkings, that is something that needs a thorough pointing out, because from where I'm sitting, he has no further involvement than any other Convocation member. A primal that is using an aether shield does not need a dynamis expert. All of his 'vital' knowledge of the root cause of the Final Days only remains vital because Venat chooses to keep under wraps that she learned basically everything valuable from him secondhand already. To be honest though, this is all from the 'rushing you out of Elpis' epilogue scene that I already have several very strong issues with.

The Watcher specifically states the first time you meet him that Hermes was the one who discovered the pattern of places where the Aether Currents were weakest and where the "Dynamis" corruption appeared first. We directly know this attributes to the "solution" of Zodiark, both Venat confirms that (before we leave Elpis) and the Watcher alludes to it just enough which means his knowledge on Dynamis is instrumental on countering Meteion first Final Days to whatever degree possible. While it's undetermined how much beyond any other convocation member Hermes participated in the construct, I think the convocation members would have been the most informed people in the solution (Zodiark). That doesn't need to be explicitly stated, as we already know they are essentially the highest members of Amaurotine society.
