Spiderfen: Terror in the Trees
A setting guide explores the province and city of Spiderfen, detailing its history, the Kiflan River, the populous eastern forest, and the dark western reaches. It describes the region’s driders, fey, hareen, and feral halflings, along with four First One Houses, major non-player characters, unique locations, and plot hooks. A map and full guide to the city are included, as well as game statistics for guards and spiders compatible with 5th Edition and Pathfinder. The largely system-agnostic material can be adapted to other fantasy role-playing campaigns.
