Tome Keepers - M37-M39 - Censure: Sanctimonia Conflict (291.M37) - In 291.M37, the Ecclesiarchal world of Sanctimonia was overrun by the forces of Chaos. Within solar months, the entire sector was ablaze with the taint of Chaos. The Tome Keepers responded to the astropathic pleas for help and -- along with a Black Templars Crusade, two convents of Adepta Sororitas Sisters of Battle and eight Astra Militarum regiments -- began a campaign of cleansing the fallen worlds. The first signs of discord amongst the allied force occurred on the Hive World of Gleb when Canoness Sophira -- a vehement witch-hater from the Order of the Argent Shroud -- baulked at the presence of the Tome Keepers' Chief Librarian Eshuh and his retinue of Librarians. Her distrust of the psykers led to a much higher casualty rate than expected, particularly when telepathic communications from Eshuh were ignored by the Ecclesiarchal forces. Less than a standard year later, on the Shrine World of Bespax, the Tome Keepers under the command of Captain Saduq were forced to destroy the Mausoleum Divinito -- a vast crypt containing the bodies of over three hundred Imperial martyrs -- when a Warp portal was opened inside it by a conclave of demagogues. Incensed by the unholy act of desecration, the Adeptus Ministorum were further enraged when Saduq pointed out that the entombed had already been martyred once and that a second time would do them no further harm. On the Civilised World of Happenstance, the Tome Keepers were to join three Dephon Astra Militarum regiments in a combined assault on a Heretic-held city. The Astra Militarum -- who were accompanied by Simonius Faulke, Cardinal Palatine of Sanctimonia -- were to engage the enemy defences while the Tome Keepers conducted a Drop Pod assault on their command position. When the city came in sight, however, Faulke ordered the Astra Militarum to advance immediately and slaughter the enemy in the Emperor's name. He disregarded the battle plan devised by the Tome Keepers, deeming their prudence and caution to be a lack of faith in the Emperor's protection and divine guidance. The Dephon regiments were almost wiped out as they launched their attack, and the Tome Keepers were forced to abort their own mission to extract them. The Tome Keepers decried Faulke's disregard for Human life. In turn, Faulke accused them of dereliction of duty. The final blow came when the Tome Keepers joined the assault on Sanctimonia. As they assailed the holy capital city, the Black Templars and Adepta Sororitas made no distinction between Heretic forces and civilians, deeming that a solar decade spent on a Chaos-held world would be enough to taint even the strongest minds. Though their actions proved to be prudent in the aftermath, the Tome Keepers would not forgive their allies for what they saw as wanton butchery and the slaughter of potential innocents. The Tome Keepers departed Sanctimonia on difficult terms with both the Black Templars and the Ecclesiarchy. Though the Adeptus Astartes are not bound by Ecclesiarchal law, nor required to follow its teachings, the Tome Keepers nevertheless found themselves unfairly vilified by other Imperial organisations in the wake of the campaign.Activation (Unknown Date.M37) - A stellar flare from the Tome Keepers' home star of GB 6-77 lit up the night sky of Istrouma for almost a solar hour. Unseen in the glare, the alien construct surrounding the star contracted briefly, then returned to its normal size.Bellrath Crusade (182-435.M38) - The Tome Keepers joined the Imperial Crusade to liberate the Laanath Rifts. Once again, poor relations with the Adeptus Ministorum led to internal conflict, which subsequently drew the searching eye of the Ordo Hereticus. Frustrated with their supposed allies, the Tome Keepers chose to fight solely alongside the Sons of Medusa against the alien race known as the Hellgrammite.
