Dungeons & Dragons

A Dungeon Master (abbreviated as DM, also known as a Game Master or GM) serves as the game's referee and storyteller, while also maintaining the setting in which the adventures occur. During each game session, the players listen to descriptions of their character's surroundings, as well as additional information and potential choices from the DM, then describe their actions in response. The characters form a party that interacts with the setting's inhabitants (and each other). Together they solve dilemmas, engage in battles and gather treasure and knowledge. Miniature figures or markers, placed on a grid, are sometimes used to represent these characters.
