Follow the Anduin river down from the chill springs of the Misty Mountains to the southern edge of the Wild! Explore the dread forest of Mirkwood, running from the lonely thickets of the north to the very gates of Dol Guldur! A resource book for The One Ring: Adventures Over the Edge of the Wild, Heart of the Wild describes the lands of the River and the Forest - the Vales of Anduin along the banks of the Great River, and the trackless forest of Mirkwood to the east. Also included is an expanded bestiary containing a host of strange creatures and servants of the Enemy, from the beasts of the forest to the fabled Great Spiders, as well as Variant Cultural Backgrounds like River Hobbits or Wayward Elves and new Fellowship Phase actions that bring the wild to life in your campaigns.
