Disturbing shadows have grown long over the northern reaches of The Land of Song. The fierce people who once fished the chilly fjords and hunted in the evergreen peaks now huddle in their villages. An evil is abroad in the land. The heroes are charged by Jarl Yngvar with traveling to the Valley of the Sleeping Jarls, an old tomb in the hills where dead kings are laid to rest, to discover the source of the malevolence bearing down upon the land and with eradicating it. Who can say what evil lurks amid the towering peaks and shadowed fjords? For decades this malevolent being plotted his vengeance upon Hjalmar’s heirs, for the jarl had gone the way of all mortals. Taking for himself the name Mogens (“powerful”), this evil spirit, now a self-styled dark lord, gathered wicked cronies and servants to itself and came to the Valley of the Sleeping Jarls. There, he has spent nearly two decades corrupting and desecrating the sacred resting place, reshaping the hollowed tombs into a blasphemous temple to his infernal lord.

The king has hired adventurers to investigate the sudden rash of giant attacks and strange phenomena around the town of Bywater. Meanwhile the townsfolk believe an evil witch is directing the attacks and only the magic sword of the town's founder can defeat her.
