Except that Enweil and Rio didn't argue. Rio just came up to us saying "Hey, we'd like a prisonner agreement. You know, just in case the north drags us into an unfortunate conflict", to which Enweil said "No. If you decide to attack us unprovoked, you assume the consequences of it. We still remember the last time we had a prisoner agreement with you, and it won't happen again." Rio stays silent for a few days, and then declares war on Enweil for it's "imperialism" and whatnot, even though Enweil was being pretty passive and repeating how it desired nothing more than peace.
I've also yet to see any battle occur. What the hell is that Riombaran army doing anyhow?
