DM is the abbreviation of Dungeon Master, originally meaning Dungeon Master, which comes from the board game Dungeon and Dragon. In the script killing, the role of DM is similar to that of the host or director. They are responsible for promoting the development of the story and are the key figures in the game. DM does not participate in the game process, but only acts as the narrator of the story. Whether you play script killing online or offline, you need a professional host to guide the game. The ability of the host will directly affect the experience effect of the game.
