The Pathfinders sail across the Arcadian Ocean, hoping to establish a new lodge on the continent of Arcadia. Following the course laid out centuries before by the Linnorm Kings, the PCs hope to arrive at the legendary Ulfen settlement of Valenhall. What they find when they arrive is a scene quite different from what they were led to expect, and the Pathfinders must deal with a number of factions, both Ulfen and Arcadian, if they hope to succeed in their mission.
