Okay, but I don't know how to work with maps though. I've looked a thread about city name maps (https://forums.civfanatics.com/threads/city-name-maps.429472/), but I see there are no files attached. Also I have some suggestions about civ names. I think that the Byzantine Empire should be named as the Roman Empire because "Byzantine" is a historiographical term that wasn't used after the collapse of the Western Roman Empire until the fall of Constantinople and has been revived to distinguish it from the "true" Holy Roman Empire. Kievan Rus' is also a historiographical term that was used first in Russian historiography to distinguish Muscovian Rus' from its predecessor and it's better to name it how it was called: as the Land of the Rus or just Rus' . Also Kiev should be named not as Kyiv, but as Kyjev, this spelling is more relevant to that period. Almost the same is about the Novgorod Republic: "Novgorod Land" is its true name.
