From publisher blurb:
Key Encounters: The Volcanic Shrine combines the writing and imagination of fan favorite Monte Cook with SkeletonKey Games' best selling miniatures-scale tiles to bring a detailed encounter to your table top. The Volcanic Shrine is a major encounter for fantasy d20 games that can be built with the 20 brand-new, custom designed miniatures-scale tiles included in the product. The encounter details the link between a massive lake of lava deep underground and the Elemental Plane of Fire itself. This encounter could be used as the center point of an entire adventure involving creatures of flame and the evil plot of a dark elemental creature known as Kaliastrix. The 20 tiles can be used to build other volcanic pools and lakes and works well with other SkeletonKey Games tile sets, including Volcanic Caves Vol. 1 and 2. The Volcanic Shrine includes guidelines for incorporating the encounter into a larger context, tips on running an encounter with lava dangers all around, and a full page encounter map of the shrine itself.
