Critical Role campaign three

The third campaign of the Dungeons & Dragons web series Critical Role premiered on October 21, 2021 and concluded on February 6, 2025; it is set after the conclusion of the second campaign and Exandria Unlimited. The series stars Marisha Ray, Ashley Johnson, Laura Bailey, Travis Willingham, Liam O'Brien, Taliesin Jaffe, and Sam Riegel as the players with Matthew Mercer as the Dungeon Master. Campaign three aired each Thursday at 7 p.m. PT on Critical Role Productions' Twitch and YouTube channels and the Beacon streaming service except for the last Thursday of each month.

The campaign is an actual play which follows the Bells Hells, a party of adventurers who met on the continent of Marquet. The campaign begins two months before the Apogee Solstice, a celestial event which influences the ley lines of Exandria and magnifies magical abilities. The party gets drawn into the mystery surrounding Exandria's second moon Ruidus and the superstitions around the Ruidusborn, people born during spontaneous flares of the red moon. They eventually discover that the gods crafted Ruidus to imprison an ancient evil known as Predathos and that the Ruby Vanguard – founded and led by Martinet Ludinus Da'leth – seek to free this entity during the Apogee Solstice. The Bells Hells attempted to prevent this by targeting the Malleus Keys, magical devices built by the Ruby Vanguard to aid their ritual. The party interferes with the ritual preventing the release. Afterwards, Ruidus is locked in place over the Hellcatch Valley Malleus Key which allows people to travel between the moon and Exandria. The Exandrian Accord brought together nations and factions from across the world to form a military alliance in opposition to the forces of Ruidus; Bells Hells, along with the adventuring parties Vox Machina and Mighty Nein, lend their aid as coordinated strike teams against various Ruidian targets.
