prior to 5.X I wanted Radz-at-han or greater extent thavnair to be a major focus in a expansion and got my wish in EW

I also would like Hingashi to be fleshed out more since there whole Isolation thing mirrors real life Japan way back when, and Doubt theyd be fine with the empire killing itself as along with Thavnair have a friendly relationship with the empire so they never felt obligated to join alliances. Also Kugane is supposed to be a small port town for trade imagine what Bukyo would look like most likely mirroring Tokyo. I love the Hingan asethetic alot and most of there land in Koshu. I imagine we will venture here after the empire dies out
