Dungeon Master

The Dungeon Master (DM), or Game Master (GM), is the planner, narrator, and referee of a tabletop role-playing game.

Dungeon Masters of Critical Role
Matthew Mercer is the DM of the first, second, and third Critical Role campaigns and some of the one-shot episodes as well. Other people sometimes take over as the DM for a one-shot game or miniseries. Aabria Iyengar was the Dungeon Master of Exandria Unlimited, marking the first time someone besides Mercer was the Dungeon Master of a full Critical Role campaign, albeit a miniseries. She later was Dungeon Master of the sequel, Exandria Unlimited: Kymal.
