Critical Role is an American web series in which a group of professional voice actors play Dungeons & Dragons. The show started streaming in March 2015, partway through the cast's first campaign. "Campaign One" ran for 115 episodes, and ended in October 2017. The cast started playing "Campaign Two" in January 2018, but the show was placed on hiatus in March 2020 due to the COVID-19 pandemic and California's lockdown measures, and returned on July 2, 2020. In the hiatus between the two campaigns, a number of one-shots were aired.
