Basically the objective of this challenge is to make Italy a germanic region by the 21st century, independent of which government or country that holds the peninsula, the PoD is the lombard conquest of italy
Just a reminder, from wikipedia:
"Over time, the Lombards gradually adopted Roman titles, names and traditions. By the time Paul the Deacon was writing in the late 8th century, the Lombardic language, dress and hairstyles had all disappeared"
So by the 8th century, the kingdom of lombards was only lombard in the name, as it got completely "italianized"
