I ran it for PF a few years back. An excellent campaign with strong atmosphere and some chilling opponents. As written, it lends itself to essentially decent characters battling some pretty nasty evils; that might not merge with the Warhammer perspective of the Norscan affinity to Chaos Gods, but it could be adapted easily enough.The Northlands Saga by Frog God Games (I think for Swords and Wizardry) is pretty solid from a story perceptive, but I haven't run it.
