This began as a Crusader Kings III playthrough. Then it was converted to Europa Universalis IV. Then it was converted to Victoria 3. Now I'm just heavily worldbuilding it. For this reason, there will be screenshots from these games included, as they are the basis for this world.
Any similarity in names with real people is entirely coincidental, unless they were well-known figures living before 867 who would obviously be in the CK3 game files.
