Flavian (Cult Demagogue)
Flavian was the leader of a Chaos Cult on the planet Kronus who conducted a sacrificial Daemonic ritual in the Deimos Peninsula shortly before the Dark Crusade. At the completion of the ritual, a Warp portal opened and allowed the Dark Apostle Eliphas the Inheritor and the Word Bearers to step forth on the planet's surface[1a]. Flavian was likely killed when the Blood Ravens Chapter defeated the Word Bearers in their stronghold in the Deimos Peninsula.[1b]
