BARRENS OF CARCOSA contains a large-scale hex map, introductory information, geographical notes, and detailed encounters keyed to the map. This module presents a complete setting for ADVANCED DUNGEONS & DRAGONS, intended for use by experienced Dungeon Masters. It can be used on its own, in conjunction with your own campaign world, or as the northeast quarter of a larger campaign area that includes THE YUTHLUGATHAP SWAMPS, JUNGLES OF THE K'NAANOTHOA, and THE MOUNTAINS OF DREAM.
Luigi Castellani's cover art depicts the Yellow Men of Dulaja worshiping a purple worm shoal.
