Critical Role (campaign two)

The second campaign of the Dungeons & Dragons web series Critical Role premiered on January 11, 2018—four months after the conclusion of the first campaign—and concluded on June 3, 2021. The series starred Travis Willingham, Marisha Ray, Taliesin Jaffe, Ashley Johnson, Sam Riegel, Liam O'Brien, and Laura Bailey as the players with Matthew Mercer as the Dungeon Master.

The campaign is an actual play which follows the Mighty Nein, a party of seven adventurers, in their travels across the continent of Wildemount. It occurs at a time of very high tensions between the Dwendalian Empire and the Kryn Dynasty—two of Wildemount's major powers, which are divided by the Ashkeeper Peaks mountain range. Over the course of the campaign, the Mighty Nein work towards rooting out political corruption, especially within the Cerberus Assembly, and establishing peace between the Kryn Dynasty and the Dwendalian Empire after war breaks out. They also thwart apocalyptic threats such as Tharizdûn's attempt to escape his imprisonment and the Somnovem's attempt to return to the Prime Material Plane.

Campaign two aired each Thursday at 7 p.m. PT on Twitch, YouTube, and Alpha. When production switched from Geek & Sundry to Critical Role Productions in February 2019, distribution on Alpha and the other Geek & Sundry channels ended; the campaign then aired on Critical Role Productions' official channels. It consisted of 141 episodes with a total run time of over 550 hours. The show has returned twice with specials set after the conclusion of the campaign – a two-part special titled The Mighty Nein Reunited in 2022 and a live show titled The Mighty Nein Reunion: Echoes of the Solstice filmed in Wembley Arena in 2023. Critical Role won multiple awards during the campaign, such as the 2019 Webby Winner and People's Voice Winner in the "Video Series & Channels – Games" category from the Webby Awards, and the 2019 Audience Honor in the "Games" category from the Shorty Awards. An upcoming animated television adaptation for Amazon Prime Video, titled Mighty Nein, was announced in January 2023.
