How do calamities work, again?

[QT_Melon]

Eh. There would have been a point where the Black Rose stopped affecting people (clearly some were immune anyways) and few enough people fighting that things would have balanced out eventually. I'm wondering what sort of world would have arisen from that? An almost religiously Pacifistic singular nation?

Question: do all civilizations that do arise from a calamity become that element, complete opposite or random?
