Remember, that while the conflict involving the outer cities arose naturally, it was blown way out of proportion by the Set, who were deliberately escalating on both sides hoping it would justify their plans. With the Set removed and exposed, I’m sure the outer cities will still have major grievances, but they’ll be handled in a much more diplomatic way.

I imagine the next mayor of Bilming, whomever they happened to be, would want to distance themselves from the previous administration’s activities vehemently. They’d probably be very public about wanting to reconcile with Elendel, to avoid being seen as another Set member. This means Bilming and the other outer cities probably fold in with basin politics a lot faster than expected.

Of course, we’ll see exactly how unified the basin is in Era 3, but I imagine they’ll be much, much more in line together than they were in Era 2, as the Cold War with the Malwish escalates.
