House Coldshroud, the “Gryphon Sires”, is a loyalist vassal Knight House (Questor Mechanicus) that fought side by side with Legio Gryphonicus throughout the Crusade and the Heresy. In the Invasion of Paramar V (the First Battle of Paramar, 006.M31) Coldshroud covered the withdrawal of an allied Titan Legion and paved the retaking of the planet with the lives of Scions at the spaceport of Paramar Nexus; the traitors there were represented by the Alpha Legion and Legio Fureans.
