Next update, the Island of Yonshu has been added and labeled. Note Yonshu is the island of Kaidan, that the entire Curse of the Golden Spear trilogy of modules introducing the setting takes place here.
I will be doing Genshu Island next. Genshu sits in the empty space at top left and top center. It's larger than Yonshu yet smaller than Anshu. It is largely wilderness with the lowest population of the main islands - it's cold here, like Hokkaido is, similar to southern Alaska in climate.
Just about done!
