In this prelude to the full Princes of the Apocalypse campaign book, adventurers face off against the influence of Elemental Cultists in the hills and canyons of the Dessarin Valley. The four mini-adventures within are only tangentially related to each-other, and instead serve as starting points and hooks for the plots of the complete Princes of the Apocalypse Campaign. Players start in the well-described town of Red Larch; first investigating a local necromancer, then uncovering cult influences within the town, and finally heading off to infiltrate or do battle with two small elemental cultist strongholds. All parts of this adventure can serve as great places to seed hooks for other campaigns.
