Every time I see another post or fic describing Argenti "saving Aventurine from the Nihility," the cranky lore-bird that lives inside the cage of my body cockatoo-screams in unbridled despair.
Who can I pay to remind the entire fandom overnight that the "Primordial Dreamscape" and the shadow of Nihility are not the same place?
The Aventurine Cornerstone protected Aventurine to the bitter end and saw him--in apparently barely coherent and very poor condition, admittedly--free of IX's shadow. We have no evidence at this point that Argenti ever encountered IX. All he says is that he discovered Aventurine in a sorry state and helped him out; zero mention of, you know, an entire other aeon.
We know from Acheron that to encounter IX is essentially impossible without contact with a Nihility emanator or falling into an existential despair so deep that you cannot return from it on your own, because IX does not gaze on anyone. While I don't think that Argenti is actually a very happy person, there's also absolutely no indication that he would abandon all his sense of purpose and meaning in pursuing Idrila to surrender to Nihility.
It is extremely likely if not already confirmed that Argenti did not rescue Aventurine from the Nihility; he rescued him from the Primordial Dreamscape (aka Dreamflux Reef and its surrounding Sea of Memoria).
Please, please, who can I pay to not have to see "Argenti was in the Nihility" anymore?
