Triple Poast. But just wanted to share.
I started out peaceful, didn't want much war with the Norse. Then I had an idea/awakening. If I took all of the towns near the mountain passes, I could shield my capital from the Norse. Now you must understand, these towns were completely empty, for the people had migrated to my capital.
So I had to:
Capture the town.
Build defenses around teh town.
Re-build the important buildings in the town.
Pick up workers from the capital, and then make them all breeders ( :D ) in the new town.
Repeat for each mountain pass.
Been a busy few hours. :D
