From the book interior: Seeds of Heresy is a Dark Heresy Second Edition adventure in which the players are sent on the orders of their Inquisitor to a seemingly forgotten agri-world, one that has been without Imperial contact for many years. A recently uncovered Astropathic message caused the planet to be rediscovered, and also expressed concerns of foul heresies within. Corruption has indeed taken root there and the players discover rival factions seeking greater power, possibly with the aid of the Ruinous Powers. On a world that has been without the Emperor’s Light for so long, can the players unravel the truth and prevent a world from falling to Chaos?
