The Warhammer scenario The Legend of Kremlo the Slann was published in Compendium 1 along with 2 sets of accompaning miniatures, WH1 Viking Heroes and WH2 Slann Warriors. These appeared on the November 1983 Trade Flyer, but became C01 Fighters and C32 Slann by Compendium 2.
It's a shame that they didn't release more of the Vikings, really great sculpts, the scenario calls for 12 beserkers amd 12 clansmen. The Slann aren't too shabby either.
