From publisher blurb: Each of the locations presented here is described by three types of maps. The first, the Dungeon Master's Map, depicts the entire location on a single page. The second, the Battlemap Outline Map, shows the DM's Map divided into smaller maps, each numbered, that correspond to an equivalent battle map. The battle maps themselves are the third type of map. These are to be printed out, taped together, and used as a playing surface by the DM and his player group. Maps for five different subterranean locations. 109 pages of one-inch scaled battlemaps. Black and white and easy on your printer!
