The daemon Cherubael is back, and seeks to bring the inquisitor to ruin - either by his death, or by turning him to the service of the Dark Gods.

The population toils in the mines and factoria to protect humanity from the monsters in the void, while the Adeptus Mechanicus enjoy lives of palatial comfort.

When he learns of a twisted congregation operating within the shadows, one which believes that the tech-priests are keeping people from their true salvation, he sees in them an opportunity to bring down Morod's masters and reclaim the world in the name of progress.
