Jove's Descent - History: Believed to be named for the Rogue Trader Hadrian Jove, in the days of the Great Crusade this world was the explorer's final resting place. His dying command, legend has it, was to send a distress signal to alert one of the Imperial expedition fleets operating near the region to summon the forces of the Imperium and purge it of the xenos that infested it.Whatever the truth of the matter, three expeditionary fleets are believed to have arrived within the region, headed by warriors of the Legionnes Astartes, specifically of the Ultramarines, Night Lords, and Blood Angels Legions, or so it is claimed by the apocryphal records of the era.Over the course of several Terran years, these expeditionary fleets brought to Imperial Compliance over a hundred and thirty worlds within what would later become known as the Jericho Reach.Jove's Descent, like many worlds in the region, was in the clutches of the Ghanathaar, an advanced, ancient, nonhumanoid xenos species who were believed to have suffered some cataclysm millennia before to rob them of much of their former power.Little now remains that refers to the Ghanathaar, save for a few scattered references in the archives of the Blood Angels and Ultramarines, and the myths of those who now dwell on Jove's Descent.As part of a protracted campaign of extermination, the Blood Angels forces made landing on Jove's Descent, waging a deadly war with the xenos inhabitants that cost the lives of thousands of Battle-Brothers.The details of this conflict are, alas, unknown to the modern Imperium, and even the Blood Angels themselves have little in the way of lore that speaks of the battles there. What is certain is that the sons of Sanguinius eventually triumphed, scouring the world of the xenos that infested it, and soon after departed the Jericho Reach for reasons unknown.The centuries that followed saw the Jericho Reach transformed into a fully fledged and loyal sector of the Imperium, and by the late 31st Millennium, the first attempts to colonise Jove's Descent were made.In the four standard millennia between the Jericho Sector's founding and the onset of the region's "Age of Shadow," eleven distinct attempts to establish Human colonies on Jove's Descent were made, none of which were successful.Each colony fell afoul of some disaster that left only desperate survivors, reverting to an atavistic state in the untamed wilds after as little as a generation.When the Achilus Crusade was first proposed, intensive research was performed on the Jericho Sector as it had been, combined with what information could be ascertained from the Deathwatch and from Adeptus Mechanicus Explorators braving the Warp Storms surrounding the region over the millennia.Jove's Descent, and its history of misfortune, were identified swiftly as a potential peril to Imperial reconquest of the Jericho Reach, and upon the commencement of the Achilus Crusade, the Inquisition saw fit to declare Jove's Descent as being under quarantine until a thorough investigation could be carried out.At present, Jove's Descent is believed to be subject to Tyranid infestation, but this is supposition based on the world's position within the Jericho Reach. None can be spared to voyage out to that accursed world and discover the truth of the matter.
