Jericho Reach - Pre-History of the Jericho Reach: Note: The following data is drawn from very limited available records.The Great Crusade (Unknown Date.ca.M30) - The volume of space later designated as the Jericho Reach is conquered during the Emperor of Mankind’s Great Crusade to unify the galaxy as a unified realm of Mankind by Imperial Fleet forces primarily under the auspices of the Ultramarines and Night Lords Space Marine Legions. The area of the Reach is sparsely populated by pre-Imperial humanity, but bears many life-sustaining and resource-rich worlds, and as such, is quickly marked as an area for Imperial colonisation and expansion. Numerous minor xenos races are exterminated in an extremely bloody campaign to bring the Reach under Imperial control, and 132 worlds are ascribed to have been brought under Imperial Compliance. Such evidence that remains indicates that the most serious opposition to the Great Crusade in the Reach was encountered in purging an entrenched Ork pocket-empire in the Reach’s Rimward portion, and most particularly in destroying the remnants of a highly technologically advanced, likely very ancient, and clearly non-humanoid xeno-form known in several records as the "Ghanathaar" who dominated the Reach’s border with the galactic Eastern Fringe. This later conflict destroys the capacity of numerous worlds in this portion of the Reach to sustain life, a factor that will shape the future Jericho Sector. The Chapel of Ages on Macragge, Chapter World of the Ultramarines, contains among its thousand shrines a Charantracite relief panel graven with the names of two thousand and thirty-three fallen Battle-Brothers who perished in the war against the "Ghan’at Hark," which is believed to pertain to this mighty conflict, but no other known records are extant.The Horus Heresy (Unknown Date.M31) - Through the foul machinations of Chaos and the sorrowful treachery of the Warmaster Horus, the Imperium is brought to the brink of annihilation by a great civil war that sees the realm of humanity shattered asunder and fully half of the Space Marine Legions turn against their Emperor. Although Horus and his traitors are defeated in the Siege of Terra, the Emperor is grievously wounded and must ascend the Golden Throne. A time of great darkness and bloodshed ensues, lasting nearly a millennium before a semblance of order is restored throughout the Imperium. As part of this, those Space Marine Legions who remained loyal are broken up into smaller, 1,000-Astartes Chapters during the Second Founding so that no such great rebellion can ever again be conceived.Foundation of the Jericho Sector (ca. Early M32) - After an interregnum lasting over 1200 standard years and often riven with bloodshed, the Imperium of Man's hold over the Jericho Reach is finally fully cemented, and it is re-designated the Jericho Sector in the great Imperium Universalis. The sector capital is the Hive World of Verronus which once served as a Great Crusade way-station and has maintained its links to the wider human domains in the preceding centuries, while the Shrine World of Eleusis gains prominence some centuries later for its native saint and because, legend claims, it was blessed with the tread of the Emperor’s own foot. The foundation of the sector is not without incident, however, as a suppression campaign must be fought against shadowy xenos forces who have begun to prey upon the stars of the southern zone around the star system of Oertha. The menace is driven off, and the [CENSORED], one of the Fleet-based Space Marine Chapters who take part in the campaign, claim title and right to the Feral World of [CENSORED] as one of their recruiting grounds, binding them in part to the defence of the Jericho Sector.
