Venture-Captain Bjersig Torrsen calls the PCs north to the town of Iceferry in the frigid Land of the Linnorm Kings. There, Bjersig informs the Pathfinders that he has a request from the family of a storied and long-dead Linnorm King. The family's patriarch, the warrior Hlavard Grenskuldr, appears to have perished in a shipwreck while wearing the family's heirloom, the gorget of the Linnorm King Grehunde the Sunchaser. For one hundred generations the family has passed this heirloom down from parent to child, until Hlavard sought to wear it on a journey to Valenhall as Grehunde herself had intended to do before perishing with the task unfinished. Unwilling to leave the relic to rust away in a watery grave, Hlavard's family has requested the Pathfinder Society's assistance in locating the shipwreck and retrieving the family treasure.
