Grey Knights - Founding: For many standard years Titan remained absent from the galaxy. While the Emperor was interred in the Golden Throne and the Traitors fled into the Eye of Terror, the Grey Knights Chapter grew within the safety of its hidden "cyst" within the Warp. As the Loyalist Space Marine Legions and then their successors among the Chapters of the reformed Adeptus Astartes hunted down the survivors of Horus' army during the Great Scouring, the Grey Knights trained and perfected their physical and psychic skill.Finally, many standard years after the end of the Horus Heresy, as the Loyalist Space Marine Legions were dividing themselves into Chapters in accordance with the newly-crafted Codex Astartes, Titan returned, just as Malcador had planned. However, time is subjective within the Warp, and where only standard years had passed in realspace, whole solar decades had slipped away in the fortress-monastery of the Grey Knights. Eight full Space Marines and hundreds of thousands of raw recruits had entered the Warp; a full one thousand Grey Knights emerged.In Malcador's stead, the Grey Knights' first Supreme Grand Master Janus had created the formidable weapon against the Warp dreamed of by the Emperor, and it now stood ready to begin its righteous task. By this time the Human lords originally gathered by the Sigillite were masters of the organisation that had become the Inquisition, and had long been awaiting the return of Titan.With great care and utmost secrecy, the Inquisitor Lords added the Grey Knights to the records of the Adeptus Terra as the 666th Chapter of Space Marines. Lost in the anarchy of the Second Founding, so many and varied were the names and Foundings of that time that few noticed the addition of another Space Marine Chapter. The only organisation to know the Grey Knights' true purpose was the Inquisition, and shortly after the return of Titan the lords of the Inquisition travelled to the Chapter's fortress-monastery where they met with Supreme Grand Master Janus. What transpired between these great lords is recorded in the annals of the Chapter, the sacred words of Janus and the Inquisitor Lords marked out in ancient ink telling of this first secret pact between the Inquisition and the Grey Knights.In the first centuries after the creation of the Grey Knights, the Chapter was called upon many times by the Inquisition. In the wake of the Horus Heresy the Imperium still burned with war and was plagued by Daemonic incursions. On the twin moons of Yyrm, silver-armoured angels were held responsible for the destruction of the Ithican Daemon Cruciform. Though none of the local citizens survived, they left behind crude drawings on the walls of their refuge-caves, depicting men clad in glowing silver impaling twisting shapes of burning crimson, all fangs and claws.The great Star-mirror of Vause records the coming of the Daemonhunters, though none of the ancient astronomers lived to speak of what they saw. In the inky depths of the mirror the fate of the Vause System can be discerned, every event to touch its worlds reflected, reaching back thousands of Terran years.When the Warp Wyrm came to Vause III to feed, a shining vessel appeared from the void. The warriors it disgorged set upon the Wyrm and its servants, cleansing Vause III in a war visible from space.During the Hell Rain of Korpolis, blind and deaf Adeptus Ministorum monks witnessed the Grey Knights banish the Khornate Styrm-lord. Huddled in the dripping cellars of their mountain sanctuary, their minds were tormented by the psychic blood rain that drowned the world. Such was the glorious presence of the Daemonhunters that even without eyes or ears the monks sensed their coming, "seeing" their deeds as fierce argent flashes in their minds.The Grey Knights fought their secret war wherever the threat of the Dark Gods appeared, seeking out those places where the fabric of reality grew thin and hungry Daemons turned their gaze to the realm of Man. This was to be the sacred duty of the Grey Knights, and their endless struggle against a foe without number or remorse.
