Jovan is a former Cardinal of the Ecclesiarchy within the Jericho Reach who has become a Heretic and an apostate. He styles himself the "High Cardinal" and "Lord of the Righteous Lost," a heretical cult of the Imperial Creed.
Recent intelligence by the Deathwatch suggests that Jovan's followers have turned a number of high-ranking Astra Militarum commanders to their beliefs, which have striking similarities to those of the Radical Horusian faction active within the Inquisition.
