Konor Campaign - Battle of Vanitor: Vanitor is an Imperial Frontier World and wilderness world that is the fourth planet of the Konor System. Vanitor is a harsh and windswept world that houses the Konor System's astropathic relay. Without this key communications outpost, the system would be left completely isolated from the wider Imperium.The Konorian Astropathic Relay, situated upon the wilderness world of Vanitor and guarded by a vast fortress basilica, once linked the Konor System's Imperial defence force to the greater war effort across Ultramar. It was one of the first targets overwhelmed in the initial blitz of the Chaos invasion, for severing this line of communication left the Konor System shrouded in darkness and confusion. Despite a brave stand, the Departmento Munitorum forces responsible for maintaining and defending the facility were encircled and slaughtered. The relay's astropathic choir were ritually bound and excruciated by Chaos Sorcerers, and the sheer agony of their torment -- amplified by the unfortunate beings' raw psychic power -- became a shining beacon to the ravenous monstrosities of the Warp.This piercing psychic scream soon came to the attention of the Grey Knights, who had swiftly identified the growing conflict in Ultramar as a potential lodestone that would draw entities from the roiling depths of the Immaterium into realspace. The grim brotherhood of Daemon Hunters knew that to allow this psychic beacon to continue to broadcast its vile signal would ultimately invite the horror of a sector-wide daemonic incursion. Gathering allies to their side, the Grey Knights assembled several strike forces and fell upon the corrupted defenders of Vanitor with merciless brutality, hacking apart Chaos-spawned horrors and their wretched masters. Yet even the Grey Knights could not accurately grasp the nightmare that was spreading across this windswept wilderness world.Upon the great plains, vast Warp breaches vomited the rancid deluge of the Empyrean into reality. Amidst the soaring Tremantaen Mountains, Heretic Astartes and their foul minions dug in like ticks, creating a circle of rockcrete redoubts around the relay, which rested atop the highest peak. Blizzards of frozen blood and transmutative hurricanes whipped through these mountain passes, birthing new flyblown horrors or flaying the flesh from those foolish enough to brave the open air. At the Konorian Relay itself, Chaos forces defended their tortured wards with savage determination, unleashing blistering cascades of gunfire and artillery upon those who looked to breach the corrupted basilica walls. If the Imperials could not break through this formidable barrier, the agony of the tortured Astropaths would only flare brighter, drowning Vanitor in the surging tides of the Warp. Surely the damnation of the entire Konor System was sure to swiftly follow.Vanitor writhed with corruption, and the roiling Warp Storms that ravaged its surface brought vast hosts of daemons into reality. Chaos forces had taken Vanitor early in the war for the Konor System, slaughtering its unprepared Imperial defenders with ease. By maintaining the furious momentum of their planetary assaults, the followers of the Dark Gods had managed to keep their foe staggered and confused, and unaware of the potential cataclysm that was brewing upon the isolated wilderness world. Yet the growing psychic disruption caused by its tormented choir of astropaths could not be masked for long. Finally freed from the apocalyptic wasteland of fire-ravaged Nethamus, Imperial fleets made for Vanitor at top speed.Having been unsuccessful in their attempts to starve the Konor System into submission by destroying Nethamus' food production capability, it was vital for the Chaos forces to maintain control of Vanitor and its twisted psychic beacon. Vast armies of Heretic Astartes, mortal Chaos Cultists and corrupted war machines flocked to the planet, establishing a fearsome network of fortifications and killing zones. Led by the Daemon Hunters of the Grey Knights, the Imperial armies crashed into these defences, blasting them apart with ceaseless barrages of bunker-breaking artillery, and relentless assaults by infantry and towering war machines. The Loyalists were buoyed by their victory upon Nethamus, and were reinforced and well-supplied. The sheer sledgehammer might of the Astra Militarum's tank regiments ground millions of cultist defenders to bloody paste beneath their relentless advance, and even the elite Heretic Astartes were sorely pressed by the sheer ferocity of the attack. It was only the endless seeping of daemonic entities into reality, drawn like sharks to blood by the power of Vanitor's psychic emanations, that sealed the doom of the Imperial forces.Slowly, inevitably, the momentum of the Imperial assault was reversed, until its armies were in full retreat. Trapped between the murderous mountain forts and tides of daemons sweeping in from Warp breaches across the plains of Vanitor, the Imperials were soon surrounded. The subsequent carnage was appalling, as the hungry denizens of the Warp glutted their eternal hunger upon mortal flesh. Less than half of the Imperial invasion force escaped alive. As the tortured screams of the astropathic choir reached a piercing crescendo, the skies above Vanitor split apart like an open wound.
