I created this scenario because I love history of Europe.
This scenario is a mini map of Europe. It is inspired by the the Early Middle Ages (Dark Ages). The rise of Charlemagne's empire (Frankish Empire), the development of Byzantine Empire, and the Muslim invasion are major events in that period.
You can play the map from the perspective of Muslim invaders, Franks, Saxons, Lombards, Khazar Khanate, Slavs, Bulgarians, or Byzantine Empire.
