I have many thoughts re: the fall of Xianle from the pov of the impact of a natural catastrophe on socio-political balance and how great natural disasters often herald the fall of civilizations via civil war and internal strife
And how there are no viable solutions to a situation like that because the forces at play cannot be reconciled even if the root cause could be ammended (which is usually impossible anyway)
And how the tensions between the people of Xianle and the people of Yong'an follow precisely the theories of human displacement and conflict stemming from resource competition crisis
And how, regardless of whatever Xie Lian might have been able to do, it would not have turned out differently for him and his kingdom, even without Human Face Disease at play
Maybe i should dust off my knowledge and write an essay
