The Dungeon Master's Guide is an essential rulebook for the D&D game and is a must-have for every Dungeon Master. A Dungeon Master is the player who runs the Dungeons & Dragons game -- part storyteller, part actor, part referee. The Dungeon Master's Guide features 224 pages of beautifully rendered, intuitively presented rules and material designed to get a D&D campaign up and running, including information on Dungeon Mastering, characters, running the game, building adventures, constructing campaings, world-building, character rewards, and magic items and artifacts.
