You could create some new religious development that arises from northern/western invaders that results in instability for a period and then a massive religious boom (after the developments sort of 'take over') that affects other regions. I don't know exactly where you could start from, but that's my two cents, haha.Anyone have any ideas for events that could happen in the Rasan Civilization? Should their cities be unified or independent of each other? Should they be pacifist like their Harappan inspirations? What interactions should they have with their neighbors(Esirta, Miscaya)?
Also, do you have a winds map of Tellurus? It would be easier to determine climate placement if you had something like that.
