Nugget reveals the location of the capital of Sotoa
It is called "Ibirsh" and is located offshore from the Sotoan Mainland. Could it be a floating city like Megafloat?
My personal theory is that Sotoa has a vast wealth inequality issue. Many people live like the woman in the trailer with the small village house, while the military and government are propped up by a network of wealthy elites. Perhaps Ibirsh is like a floating Dubai, and the country is facing the desertification crisis in part due to overconsumption from their lavish, tourist-drawing infrastructure.
In that case I could see it making sense that the elite would move their capital literally away from where the problems are. I can see there being some visual theming between the war-torn cities and towns of the FCU and the upscale skyscrapers in Sotoa.
