Sabbat Worlds Crusade - Sabbat Worlds: Situated along a rimward portion of the Segmentum Pacificus, the region now known as the Sabbat Worlds Sector was first annexed for Imperial colonisation in the 35th Millennium.This often volatile region of space is composed of over 100 Human-inhabited star systems, subdivided into a number of discrete territories or sub-sectors, most notably the Newfound Trailing, the Khan Group, the Cabal Systems, the Carcaradon Cluster and the Erinyes Group.It is rumoured that the Blood Pact, a highly organised Chaos warrior-cult devoted to the Blood God Khorne, originally came from a star system in this sector.First annexed for Imperial colonisation in the 35th Millennium, the name Sabbat refers to the area's original redeemer, Saint Sabbat, a young girl who received a vision from the Emperor of Mankind to bring the region into the Imperium during an Imperial Crusade that lasted for 105 standard years and began in 500.M35.By the 37th Millennium Mankind was well-established throughout the region, with an estimated population of roughly five trillion and a thriving local, interstellar economic infrastructure. However, due to its exposure to the eternal threats of the outer dark along the galactic rim, control of the Sabbat Worlds was ever disputed with the forces of Chaos and various xenos species.Throughout the 38th Millennium, the region suffered a series of brutal wars and conflicts with the barbaric Chaos-worshipping Human tribes of the so-called "Sanguinary Worlds," located further rimwards of the spinward extent of the Sabbat Worlds, and the area soon became known as a "troublesome province" to the Administratum.However, during the first centuries of the 41st Millennium, the situation altered drastically. A charismatic, brutal Chaos warlord known as an "archon" rallied the tribes of the Sanguinary Worlds to war, and a series of assaults began from galactic trailward into the region.The assault was thought at first to be a return to the minor Chaos conflicts of the 38th Millennium in the region, but in the standard years following 600.M41, it became impossible to ignore the true threat presented by Chaos Undivided.The Ruinous Powers had decided to take the whole region away from the Imperium and their chosen forces launched a series of devastating attacks into the sector, conquering and destroying everything in their path. The ultimate goal of the forces of Chaos in the sector was to drive out the Imperium and reestablish their mastery over the worlds they had been driven from by Saint Sabbat and her original Imperial Crusade in the 35th Millennium.These Sabbat Incursions were just one of a half-dozen major Chaos invasions suffered by the Imperial star systems of the Segmentum Pacificus during this period. The Imperial defence of the Sabbat Worlds proved valiant but ultimately unequal to the task, though it should be noted that the Imperium was simultaneously fighting eight other significant campaigns throughout Imperial-controlled space during this period.To consolidate their lines of defence, the Segmentum Pacificus High Command had to make bitter decisions, sacrificing certain portions of Imperial space in order to enhance the Imperium's best chance to resist the Chaos onslaught.Severely underestimating the archon's forces, the segmentum High Command tried to do what they thought best for the Sabbat Worlds. But ultimately, the meager Imperial defence was not enough and the sector was conquered wholesale by the servants of the Ruinous Powers, returning the Sabbat Worlds to their heretical roots.The Sabbat Worlds were swiftly reconquered and occupied by the archon's forces, although many Imperial worlds in the region continued to resist as isolated outposts of the Emperor's light in a vast sea of apostasy and heresy. Some managed to hold out for solar decades, whilst others managed to do so for more than a Terran century.Unfortunately, by 740.M41, the Sabbat Worlds could no longer be considered to be under Imperial governance, as this "troublesome province" was reclassified by the Administratum as an "unstable/hazardous" region of space.In 741.M41, the Civitas Imperialis was officially suspended in the region by the Administratum and the sector's lord governor was moved to a neighbouring sector for his own safety. The Sabbat Worlds were from this point forward regarded as entirely lost to the Imperium, having become dominions of Chaos.
