Dungeon Master

A term, created for the Dungeons & Dragons game, that describes the player who fulfills two important functions during a roleplaying game: referee and storyteller. As the rules for Dungeons & Dragons are vast and complex, it's the job of the Dungeon Master to facilitate gameplay and to determine the outcome of contested events by deciding how to interpret a given rule or dice roll. It's also the job of a Dungeon Master to provide the setting for the players' fictional characters, create goals for the characters to accomplish, and to fill any supporting roles needed for the adventure (kings, princes, dragons, innkeepers, barmaids, villains, etc.). The ultimate goal of a Dungeon Master is provide a fun and satisfying challenge for the players to overcome, through acting, exploration, puzzle-solving, and scenario-based decision-making.
