Yeah, thought it was Tenebrae (especifically that white bridge). I'm happy it isn't and it isn't shown in that map, so there are surprises as to when it shows up in the game.
And what a shame, Naora is the GOAT, one of those people that defines FF (like The Gooch, Uematsu...), or at least the modern-ish ones. And it hurts more when I think about him being the designer of old Noctis, as I wanted him to tackle on XVI's character designs or at least follow that trend.
He seems to be going freelance, so maybe he'll work with S-E in the future, much like Yoshida. Hopefully, as he's talented as fuck and has been essential in making FF what it is/was starting with VII particularly.
