From back cover: "Meet intrepid rivermen, banished Dúnedain, reclusive Elves, and the shrewd Dwarves of the Nan-i-Naugrim while roaming Numeriador's untouched scenery. Roaring waterfalls, snow-capped peaks, and deep forest whose shadows hold beasts and monsters surround the isolated hamlets and farmsteads where only the fearless and hardy dare dwell. Far from the comforts of civilization, travelers face marauding bandits, hungry Trolls, and the spies of the Witch-king throughout this frontier."
