From the back cover: Few adventurers who ever enter the legendary halls of Dwimmermount ever return. Its dangers are too great – its mysteries unplumbed. If only a map were at hand – or better, a dozen maps, one for every level of the dungeon… Dwimmermount™ is a classic megadungeon and old-school campaign setting presented for use with Labyrinth Lord™ and other d20-based fantasy role-playing games. The Dwimmermount Map Book presents each of Dwimmermount's wilderness, dungeon, and fortress maps as a two-page spread for reference and annotation in play. It’s an indispensable reference when running a dungeon that’s large enough to encompass an entire campaign! The Dwimmermount Map Book also includes a special two-page visual timeline of the construction of Dwimmermount, showing its origins in the early First Era to its final completion millennia later. This is not a standalone product. A copy of Dwimmermount™ is required to run the dungeon. Dwimmermount is a 13-level megadungeon for Adventurer Conqueror King System™, Labyrinth Lord™ and other d20-based fantasy role-playing games, available for purchase separately from Autarch™ LLC.
