From the back cover: A series of small earthquakes have brought a sense of disquiet to the town of Daern Kelton and Roslof Keep. Against these strange earthly portents, the members of the Ivory Scimitar have claimed their place as a true Mithel Company, but even greater danger now awaits them in the second level of the Dungeon of the Black Fey Mithelvarn. What lost secrets will be revealed as they journey below? What new threats and adventures can be had in Daern Kelton? The town now opens its doors to the brave new heroes of the Company of the Ivory Scimitar. Here continues the Roslof Keep Campaign in the pages of ROS2, The Tremors in the Machine.
