I was more speculating on what Delita was doing next. By the end of the war, the heads of virtually all the major houses are dead and he had strong support from the commoners, so it’s certainly possible he just upended the whole system. We don’t know, though. Given Delita made his deal with the church to rise to power and it taking centuries for the truth to come out, I’d say it’s implied that from then on Ivalice became a theocratic state or went heavily in that direction.
And yeah, the joke has been that it’s only there because JRPGs always have to have some sort of high stakes, non-human confrontation. I think Matsuno handled it much better in Tactics Ogre than he did here.
