When a decadent noble uncovers a heretical artefact of dark origins, the Inquisition is sent on an investigation from his palace to a lost fortress on a distant world. Can you solve the mysteries of the Haematite Cathedral before it’s too late, and uncover a conspiracy that threatens to set the Calixis Sector ablaze?

The Black Sepulchre, an adventure for Dark Heresy, tasks Acolytes with solving the riddle of an ancient and powerful structure. In the process, they’ll uncover a truth so dark, the Calixis Sector may never recover from its discovery...

The Black Sepulchre is the first installment of The Apostasy Gambit, a Dark Heresy campaign that takes a cell of Acolytes from investigating the tragic history of a warped Cathedral to crusading against a conspiracy at the heart of one of the Imperium’s most vaunted organisations. The Black Sepulchre can be played on its own, or it can form a part of the grand Apostasy Gambit campaign. What’s more, this adventure is designed for all levels of play, so beginners and veterans alike can explore its varied paths to success!
