Once known as the Order of the Emperor's Tarot, the Coven of Dark Fates is responsible for the spread of Chaos throughout the Ecclesiarch controlled Steel Saint Sub-Sector. At the core of this fallen Coven is the Rogue Inquisitor Xen John, who had caused the fall of the Order of the Emperor's tarot to Chaos, and the Order's former Prioress Sister Mae Summers. Together with an army of fanatical followers and a keen knowledge of the inner most workings of the Imperial Cult these two have begun a crusade of liberation freeing several worlds from the lies of the Imperial faith.
