From the back cover:
Explore the lands of Scandinavia in the time of Beowulf and King Arthur.
While Arthur sat upon the throne of Britain, Beowulf drank mead in the halls of Hrothgar and battled Grendel for the glory and honour of his king.
Land of Giants is a supplement for the King Arthur Pendragon roleplaying system, describing Scandinavian kingdoms as they existed in the time of King Arthur. This book features notes on generating Northman characters, a survey of Northman customs and religion, a guide to the region and new adventures.
Gamemasters can use the Scandinavian kingdoms as a place of adventure for their Arthurian player knights, or play the Thanes and Jarls in a purely Northman campaign outside the influence of Arthur's rule.
