Faerun

Running along the Sea of Swords from north of Arnn to the Sea of Moving Ice, the Sword Coast is a narrow band of territory dominated by the city-states of the area that use the sea for trade. For most who care about such things, the area is delimited by Neverwinter in the north and Baldur's Gate in the south, but territory farther to the north and south that isn't under the sway of a more influential power is usually also included in maps of the Sword Coast. More broadly, the North refers to all the territory north of Arnn, split into two general regions: the Western Heartlands and the Savage Frontier. The Western Heartlands encompasses a narrow strip of civilization running from the Sunset Mountains to the Sea of Swords, and northward from the band of territory marked by the Cloud Peaks and the Troll Mountains to the Trade Way. The Savage Frontier is the name given to the rest of the unsettled or sparsely settled territory in the North, not including the major cities and towns and any settlements in their immediate spheres of influence. Most of the communities, nations, and governments of the North can be grouped into five categories: the cities and towns that are members of the Lords' Alliance, the dwarfholds that have been built throughout the area, the island kingdoms off the coast, the independent realms scattered up and down the coast, and the subterranean environs of the Underdark.
