From the introduction: This guidebook is meant to help GMs of Dungeon World develop adventures and campaigns taking place in a forested environment. It was written with Dungeon World in mind, but it could be adapted for a variety of other games. Feel free to use elements from the book as they are or change them around to fit in with your universe. The forests described in this guide are inspired by the temperate forests of my home states of Arkansas, Colorado and Oregon.
