A Dungeon Master (DM) is the person who facilitates a tabletop role-playing game, most commonly associated with Dungeons & Dragons. The DM is responsible for creating the game world, narrating the story, and controlling non-player characters (NPCs) while guiding players through their adventures. This role requires creativity, storytelling skills, and a deep understanding of the game mechanics. In addition to managing the narrative, the DM also acts as a referee, ensuring that the rules are followed and that the game remains enjoyable for all participants. The DM's decisions can significantly impact the game's direction, making their role crucial to the overall experience.
