This is a viking warfare map meaning you will be raiding with your longboats very much. Good luck watch out for more maps soon :D
You have taken the inner part of Scandza and become the High King but not all accepts your rule there are rebels that have set up near your kingdom they call you a traitor to the old crown and demand your head they are commanded by a rebel leader who is in his own keep further to the north.
Defeat theese rebels and proclaim your dominion over theese lands.
Only after you kill theese rebels that you may enter the frozen north.
