This role encompasses the facilitator and narrator within a tabletop role-playing game (TTRPG) set in a realm distinct from the familiar world. This individual guides players through a narrative, adjudicates rules, and portrays non-player characters (NPCs) within this unique setting. An example would be someone leading a group through a fantasy adventure in a world inspired by Celtic mythology, or a science-fiction exploration of a dimension accessible through a quantum anomaly.
The individual in this role is essential for providing immersive experiences and compelling storytelling. Their ability to create and manage the setting, along with the characters and challenges within it, directly impacts player engagement and the overall success of the game. Historically, this function was often fulfilled by the most experienced player, but has evolved into a recognized skill set that combines improvisation, worldbuilding, and interpersonal communication.
