Loebos - The Loebos Campaign: As the war in the Konor System reached its crescendo, dire Vox reports filtered in from the far edge of the region. The Death World of Loebos hurtled across space like an enormous wrecking ball, trailing a vast cloud of spore-ridden asteroids and noxious gases. This was Mortarion's final gambit for the conquest of the Konor System -- a world weaponised, powered by continent-sized engines and the fell power of the Warp. If Loebos' furious momentum was not stopped, the system-wide war still raging would be rendered irrelevant. The Death World would barrel through the system like a plague comet, trailing corruption and death in its wake, infecting world after world with Nurgle's pestilential gifts.Long-range scans of the onrushing world have revealed the source of its momentum. Gargantuan fusion-powered Warp-Drive arrays cover Loebos' southern continent, flaring with the power of a supernova. These are engines that once powered a number of the Death Guard's vast Space Hulks, grotesque vessels from which Nurgle's chosen launch their raids into Imperial space. Through some form of dread Warpcraft, these enormous devices have been transferred to the surface of the Death World, and their colossal power has wrenched Loebos out of its circumsolar orbit around the star of Konoris and sent it speeding towards the heart of Ultramar.The only option left to Imperial High Command is to order an all-out assault upon the world, in the hope of sabotaging the Warp engines or destroying the planet itself with a well-placed Cyclonic charge. Such a task will not be easy. The Death Guard have established towering fortresses across the only viable landing sites on Loebos, and holo-picts indicate that Chaos forces are stationed across the equatorial belt in unthinkable numbers.Such a fearsome garrison would be terrible enough, but the planet of Loebos itself is perhaps the gravest threat to any who set foot upon its surface. Long ago the Imperium attempted to settle Loebos, only to discover that it was in fact an Aeldari world, populated by Exodite tribes. The fighting that followed was brutal, and the Aeldari population was massacred by regiments of Imperial heavy tanks and campaigns of intense firebombing. This wholesale slaughter sent Loebos' tormented World Spirit mad with grief and rage, and it lashed out at the invading humans with every weapon at its disposal. Loebos' flora and fauna fell upon the Imperial forces. Regiments of infantry were torn apart by razor-thorn vines, and tanks were dragged into bubbling acidic swamps. Only a fraction of the Imperial invasion force escaped Loebos alive.The corruption of Nurgle only exacerbated the world's vengeful insanity. Moats of foul corpse-water ridden with every toxin imaginable kept the Chaos defenders safe within their fortifications, but any troops fighting in the wilderness had no such protection. Every available force was directed towards Loebos immediately, for time ran short. The battle for Loebos was nothing like the Konor System had ever experienced, a nightmare of apocalyptic proportions. Thousands of vehicles and millions of warriors were ground up in a murderous meat grinder, and the environment itself sought to slaughter and devour the combatants, no matter their allegiance. Yet the Imperium had to destroy Loebos, by whatever means and no matter the cost, lest the war for the Konor System ended in system-wide devastation.There was no sense in the Imperium of Man withholding forces from the assault upon Loebos, for if the corrupted Death World remained on its relentless course, there would be little of the Konor System remaining to save. As the planet soared through space, trailing Warp energies in its wake, the Imperial Navy launched every transport ship, cargo hulk and Battlecruiser available, each vessel packed with soldiers and vehicles. This makeshift fleet made for low orbit, even as the vast Chaos armada escorting the Death World blasted thousands out of the skies in an eruption of coruscating fireballs.Though the first wave of the planetary assault was almost entirely obliterated by ground fire or torn apart by circling clouds of Plague Drones, the second and third made landfall. Even as the Loyalist troops rushed forth to pre-designated positions, the maddened forests of Loebos came alive around them; barbed vines snatched screaming troopers away into the shadows, crystal-bladed trees impaled tanks and combat walkers, and pools of sizzling acid devoured landing ships whole. Yet, led onwards by the fearless champions of the Adeptus Astartes, the Imperial advance pushed through the lethal wilds, through vicious enemy fire and the worst that the maddened Death World could throw at them. Soon, the great Death Guard fortresses of the Trifectum Putris were crumbling under a relentless firestorm of super-heavy tank shells.At the Circle of Mehnauris, the raging centre of the World Spirit's agonised torment, a shimmering portal emerged and disgorged ranks of agile, graceful warriors and speeding grav-tanks. The Aeldari had returned to their shattered world, and they brought with them the righteous fury of vengeance. With sword and Shuriken Cannon they struck at the contamination that had so corrupted Loebos, shattering the foul icons of Chaos that littered its surface, and slaughtering any worshippers of the Dark Gods they laid eyes upon. Some Craftworld warhosts, fueled by grief and horror at the fate of Loebos, took the opportunity to enact their revenge against the Imperium's warriors, who had so long ago savaged this once pristine world. Yet the majority of their wrath was spared for the servants of the Dark Gods, from whom they enacted a bloody toll before vanishing back into the Webway.Meanwhile, strike teams of elite Imperial warriors breached the Chaos perimeter at the Decay of Hope, the largest of the deconstructed Space Hulks powering the Death World's unnatural momentum. They ventured deep into the Warp-touched halls of that dread vessel, encountering mind-shattering nightmares and slavering, flyblown horrors with every step forward. At unthinkable cost, they advanced as far as the fusion core of the great engine array, where they manually detonated a Cyclonic warhead. The resultant cataclysmic explosion enveloped the entire southern continent of Loebos in a coruscating firestorm, setting off a series of chain reactions that ruptured the planetary core. As the remnant of the Imperial forces desperately fell back to evacuation points and made for high orbit upon the remaining transport ships, the tortured world of Loebos began to come apart. In an eruption of white light, the Death World detonated. Huge chunks of the planet were sent rocketing through space, shredding Imperial and Chaos vessels alike, yet no neighbouring world of the Konor System was touched by the devastation. With the death of Loebos, the Konor System had been saved from utter ruin.
