Cleansing of Opridia
From Warhammer 40k - Lexicanum
In 972.M41, Inquisitor Lord Torquemada Coteaz of the Ordo Malleus led the planet-wide exorcism of the planet Opridia, casting out a million Daemonhosts and carrying out the banishment of the Daemon Prince Karpathi the Occludor. Crucial to the Inquisitor's victory was the deployment of the Second Company of the Exorcists Chapter, whose Librarians enacted the Rites of Detestation which are unknown to those outside of their Chapter Cult.[1]
