I've been thinking, which region would be the one with the most possibilities for the story to continue. And I think, unless new things happen elsewhere, it would be one of two:
1- Rauatai:
With the end of storms across the region, it is a place where there can be many changes. But it is true, that it would be repetitive to be again in a country of aumaua.
2- Yezuha:
This region that Rekke presents us, presents us with something new. A land where the "gods" of Eora have not promulgated their doctrines. And also, being a country unknown to the rest of the powers, there would be many conflicts. The Republics would fight for trade, Rauatai may have tried to conquer it, and Aedir would send missionaries and inquisitors to bring them the "true" faith.
What is your opinion? Or also ... In which region would you like the game to take place?
