Is there a certain ascetic or overall, "culture," if you will shared throughout the North? IE is the North representative of say Celtic/Germanic/Norse culture at the time of their respective Christianization, or would it be kosher to have a society based on whatever the players feel like? I mean, if someone wanted to have a society based on Ming Dynasty Chinese culture, albeit with acknowledgement of Aed, would that be allowed? Or should these societies be based on European cultures as they were first Christianized?
