Let’s separate two different claims. One is that dynamis is unknown to everyone but Hermes, and the other is that Hermes is a foremost expert at the time of the Final Days. The latter is true, the former not.
You realize this is you personally judging it to be contradictory right? If the game, as you admitted it does, says she sees them a certain way, and you go “no that’d to me seems contradictory,” that doesn’t mean the game didn’t say that. It means you’re rejecting evidence to the contrary of your stated opinion.
You do in fact realize that those “old ones” were not physically harmed or altered by the act of enervation yes? They still retained their personalities and attributes.
And even then whether intelligence was halved is questionable.
The reason why she was not open to all of what transpired at Elpis was stated clearly in the text. If you wish to argue that those reasons aren’t valid, then we can discuss that, but to ignore that and insist that she freely chose to deny them that information is unfounded.
You’re allowed your feelings, I don’t have beef and quite like the localization efforts so I can’t agree but that’s no really important.
Yes concepts were stored and regulated so as to allow their use more broadly, this I agree with. My point however is that the Bureaus work went beyond being a repository and seemed to make no distinction in a concept meant for large scale use and one made for personal reasons. Ifrita, Phoenix, Meteion, and innumerable other creations were never intended for wider use, but were submitted all the same. Hythlo when he asks Hermes of Meteion never asks what his intentions are with her, and in fact that doesn’t come up until later when Hermes freely tells us while explaining dynamis.
But perhaps I am overestimating the Bureaus reach, it’s clear they don’t have much of an enforcement arm. Still the fact remains that Hermes background with dynamis is unique and his experiments one of a kind.
Then let’s return to the original topic then. The question remains, can Hermes be replaced and is their a good reason to believe that a creation with the ability to control dynamis could defeat Meteion and thus make the Sundering unnecessary? My answer is of course no to both, based on what we know of Hermes and based on what we know of how dynamis works.
