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! Enter the heart of the Wild, and defend it against the rising Shadow. A Sourcebook for Adventures in Middle-earth, the Rhovanion Region Guide 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. It expands on the description given in the Adventures in Middle-earth Loremaster's Guide, offering new sanctuaries and new perils for players to discover. Each region is described in detail, listing potential friends and foes, sites of interest, and potential adventures. Also included is an expanded bestiary containing a host of strange creatures and servants of the Enemy, from the bests of the forest to the fabled Great Spiders, as well as variant cultures like River Hobbits and Wayward Elves that offer new options for adventurers.
