The Perilous Expeditions Set is a new Narrative Campaign mode that expands Shadows of Brimstone in exciting new directions. The heart of the Perilous Expeditions Set is the Narrative Campaign Book which includes all the Rules Campaign Objectives Story Threads Enemy Lists Expedition Hazard Charts for Land and for Sea for both the Norse Coast and the Jungle Island Chain as well as a host of other new material including 8 brand new Missions for use with the Expedition Ship Board the Wilderness Encounter Board and some unique Campaign Story Missions. Heroes use the Gold and Dark Stone they collect on Missions to upgrade their Expedition Camp and Ship over the course of the Campaign unlocking new options and powerful bonuses as the Darkness grows ever-stronger.

Heroes explore the Campaign Map to reveal Adventure Locations travel to OtherWorlds and back hunting down Campaign Clues that lead you through the Story and eventually (if you survive the perils thrown at you) reaching a climactic final push to defeat whichever powerful creature or sinister scheme the Darkness has unleashed upon the world!
