Honestly given that Zodiark’s purpose is Salvation, i fully expect him to be the key to combating the sound or reversing the effects of the terminus beasts, because even if we defeat whatever is behind the sound, it isn’t going to reverse the damage it caused, and he’s the only one that was capable of getting rid of it. Would be interesting if we finally got to use the blessing of dark and the warrior of darkness title wouldn’t be a joke anymore.
