Critical Role is a weekly actual play series featuring a group of professional voice actors and actors playing Dungeons & Dragons to create longform improvisational stories, primarily in the fantasy world of Exandria. The show began in 2015 as a livestreamed version of a private home game that started in 2013, led by Game Master Matthew Mercer. The series is broadcast live on Thursdays via Twitch, YouTube, and CR's Beacon streaming service, with video on demand available shortly after, and publicly on YouTube the following Monday. The show features three completed campaigns set in Exandria: Campaign One (Vox Machina), Campaign Two (The Mighty Nein), and Campaign Three (Bell’s Hells), which concluded in February 2025. Campaign Four, set in a new world called Aramán, began on October 2, 2025, with Brennan Lee Mulligan as the new Dungeon Master and a rotating cast of players. The series has inspired a resurgence in Dungeons & Dragons' popularity and has led to various licensed works, including comic books, official campaign setting guides, and animated series such as The Legend of Vox Machina (2022) and the upcoming Mighty Nein (scheduled for November 19, 2025).
