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 24" x 24" play area from a set of books that fits on your bookshelf and in your bag!
