The Norse have been sailing where they want to, trading for or just taking what they want, and going back home to enjoy life for thousands of years.  They gave up the raiding bit in favor of just having fun a while back, and I have to say I approve.  They jumped into The War pretty quick though, and I got to serve on the Tordenskjold.  Good Norwegian name that one.  Good Norwegian ship too.  I loved going a-viking with her.
