So, maybe its just me, but I feel like the world info does a somewhat poor job of telling us why the CAS left besides "something something economy not the CSA something something". When I read SoNA, the CAS section open with the whole "slavery was nit the civil war cause myth", then disavows the CSA, then talks about how similar the two countries are. They feel the same sabe for a few name changes.
So, here's the question: is there some sort if Secret History behind the CAS seccession? Or is it a case of "make the map look cool"?
