After some time, and some discussion, I have made some changes to the map op Ianna and Terria, that will impact the Twin Worlds slightly.
The original though behind the World of Ianna, where island kingdoms, where the main mode of transportation would be by boat of with the aid of magic. Whereas Terria would be on massive landmass, dotted by city-states and would be the beacons of light within the world. These changes to the maps should bring focus back to these original ideas.
This doesn’t means that the kingdoms, city-states and landmasses are gone, the might reappear in later publishings.
