Shadowkeepers - Notable Campaigns: The Burning of Prospero (004.M31) - Several sodalities were drawn from the so-called "Warders of the Vaults of Rython" which were deployed as a part of the Imperial Censure Host, Terran Contingent, serving as the reserve second wave behind the lead elements commanded by Captain-General Constatin Valdor during the assault on Prospero. The fact that these forces were deployed as a part of the Censure Force is itself something of a mystery, and one some have suggested speaks to a need to call upon reserves more desperate than was outwardly understood at the time. Vitally, the Warder Sodalities resisted the circling counterattacks made by the Thousand Sons forces during the Battle for Tizca's cataclysmic final hours, holding back their psychically-augmented onslaughts when the merely human troops defending the Imperium's supply lines and landing zones broke and were slaughtered around them.The Ominous Gift (Unknown Date.M33-M39) - At some point between the 33rd and the 39th Millennia, Halo-belt Augurs reveal the Space Hulk Ominous Gift advancing inexorably out of the dark void towards Terra. Using his status as a High Lord of Terra to overrule objections by the Imperial Navy, Captain-General Aesoth Koumadra orders a strike by several Shield Companies to gut the craft from the inside and ensure its corruption is wholly purged. Those outside the Adeptus Custodes do not understand the significance, but the attack is led by the Lockwarden of the Shadowkeepers and a band of his black-armoured comrades. The Ominous Gift is destroyed -- and the wider Imperium need never know any more than that.The Years of Madness (Unknown Date.M41) - Whispers engulf Terra, beginning with the disappearance of the notoriously conservative Captain-General Galahoth. Battling the stagnation of Galahoth's rule, the Adeptus Custodes find themselves facing a shocking increase in cult activity -- both heretical and xenophile -- throughout the Sol System. Doomsday sects trigger queue-wars between the pilgrim tribes within the Emperor's palace itself, and the Custodians are forced to exercise their authority in the bloodiest fights they have seen in centuries. Reports from the Dark Cells cite a growing sense of agitation amongst the hidden inmates, and numerous support Servitors have to be destroyed by the Shadowkeepers after they exhibit sudden, violent madness. Worse is to follow as possession is revealed amongst a sub-sect of the doomscryers of the Imperial Palace themselves, though not until the false predictions of the fallen psykers send Captain-General Launceddre to his death at the Battle of the Gilded Pyre. It is amidst this climate of spiralling paranoia and danger that Captain-General Trajann Valoris is elevated to command the Ten Thousand, and he wastes no time in taking steps to regain ironclad control of Terra's defences.Into Shadow (Unknown Date.M42) - Upon the direct orders of Trajann Valoris, a small, fast-moving force of Custodians makes haste for the ruined remains of Cadia. Details of their mission are suppressed, even amongst their comrades, but they are accompanied by a number of warriors drawn from the ranks of the Shadowkeepers.
