THE MOUNTAINS OF DREAM 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 southeast quarter of a larger campaign area that includes THE YUTHLUGATHAP SWAMPS, BARRENS OF CARCOSA, and JUNGLES OF THE K'NAANOTHOA.
Luigi Castellani's cover art depicts a fighter, a magic-user, and a cleric of Cthuga daring the enchanted tree in the midst of the inexplicable Garden of Snows.
