At the request of the reincarnated Saint Sabbat, the Tanith First-and-Only is summoned to the remote and tactically insignificant world Herodor. The Civitas Beati, a holy city dedicated to the Saint, is under assault from a legion of Blood Pact, led by Enok Innokenti. While the Ghosts prepare to defend the city alongside the local PDF force, Gaunt learns the truth of the situation: the woman posing as the reincarnated Saint is Sanian, an esholi whom the Ghosts encountered on Hagia. Utterly convinced that she is Sabbat, Sanian has clearly lost her mind. Lord-General Lugo – whose career has been unstable since his disgrace at Hagia – plans to use her as propaganda, and does not care that she is an imposter; he believes that he will be forever remembered as the man responsible for a miracle in the Sabbat Worlds. As far as untold thousands of pilgrims, Imperial and archenemy troops are concerned, Sanian is the true Saint.
