Raiders of the North Sea is a strategy board game set in the central years of the Viking Age. As Viking warriors, players raid unsuspecting settlements, plundering gold, iron and livestock. There is glory to be found in battle, even at the hands of the Valkyrie. In order to win, players must obtain the most victory points by raiding settlements, taking plunder, and making offerings to the Chieftain. How players use their Plunder is also vital to their success.
