Cruentis Petram was founded by Jeremiah Vercius ex Jerbiton and Videnaeci ex Criamon. It consists of a collection of stone buildings protected by a wooden wall and ditch in the woods north of the village of Scratching Hill in the Yorkshire Dales. The centre of the covenant consists of a rock formation from which a silvery substance 'bleeds', yielding four pawns of Terram vis a year.

The two founders of the covenant were slain in 1226, Jeremiah by a young girl that had been taken in to the covenant who was thought to have Divine origins, and Videnaeci by a Demon that came to collect the girl. The girl was aided by Drogo, the Turb Captain at the time. Recent evidence suggests that Drogo may have been an agent of the Infernal all along.

Most of the current magi joined the covenant in 1221, having been pushed in its directly by the Jerbiton maga Isabelle as part of a plot between herself, the two founders and some other Criamon and Jerbiton magi who believed that Jeremiah had come from another world which had suffered its own apocalypse. They believed that the next Saviour would be found near York, and had set up the covenant to involve themselves in the predicated events. As it happens, things didn't turn out well for their plot.
