Formable ‘Magna Germania’
Magna Germania was the Roman term for the historical region in north-central Europe initially inhabited mainly by Germanic tribes.
It extended from the Danube and Main in the south to the Baltic Sea, and from the Rhine in the west to the Vistula. The Roman portions formed two provinces of the Empire, Germania Inferior to the north (present-day southern Netherlands, Belgium, and western Germany), and Germania Superior to the south (Switzerland, southwestern Germany, and eastern France).
This modification gives players the chance to form a fictional ‘Magna Germania’ tag, which signifies the unification of all the Germanic tribes in the region. Feel free to leave suggestions!
