DnD is a collaborative storytelling game where one person plays the narrator and supporting cast while everyone else plays a main character. The DM will lead each game session, develop adventures, adjudicate the rules, and fill the worlds you adventure in with people, places, and things to interact with! The role of DM can be a daunting task at first, but for people that find themselves interested in building the framework of heroic stories, it's an unbelievably rewarding experience.
