Attention Adventurers! Grab your dice and get ready to roll initiative as the game is afoot and it just went modular! The Dungeon Books of Battle Mats offer two adaptive books of RPG battle maps which line up to create one endlessly evolving dungeon. Standard entry/exit points and a 360 spine allow you to create anything up to a 24x24 play area from a set of books that fits on your bookshelf and in your bag!
