Perhaps I just overlooked it, but I thought of something when I played through the game for the umpteenth time yesterday. . .
After the Esper World finds its way into the sky, what happens to Banon and Arvis? I mean, they're both in Vector when the city gets razed and you have the banquet with Gestahl, right? Then, your crew gets tricked, but they're able to escape Vector in time. But, after you leave Thamasa and the Floating Continent appears, the two of 'em are nowhere to be found.
I went back to Vector and no one was there. I went to the Returner's hideout, and they weren't there, either. Then I went to Narshe and checked Arvis's house and the elder's house and didn't have any luck with those.
When you think about it, as two important leaders of the main resistance force, it would be nice to know what happened to 'em, right? Of course, I could've just looked past something, but it would be nice if someone knew.
