I'm trying to remember if this thing has been here the entire game and was just inaccessible or not.
It isn't. Even if you go there earlier in the Finale.

I think that's about everything, but I didn't get the trophy for completing every sidequest, so I decided to check and see if I missed anything or if something unlocks later or something. Turns out there was a friggin' hidden monster in the Geofront in the last part of Act 3, how lame. I don't remember anything popping up for the Geofront as new at any point, so I didn't bother to check it out, bah.
Ah, that sucks.
The ???/Argres quest only pops when you do all the other Finale sidequests (and beat all the cryptids) so you should be good to go on that. Only thing that comes to mind I don't recall you doing is if you tried getting into Orchis Tower again since you couldn't before. I think you may have had to do the SSS sidequest if the game wouldn't let you in through the Geofront entrance near Jona before.
