Death Guard - Time of Outbreaks, M41-M42: Note: All dates from this point forward are provisional due to errors in the Imperial Calendar, meaning these events could actually have occurred at any time from the early 41st Millennium to the early 42nd Millennium.Galactic Epidemic (ca. 999.M41-Unknown Date.M42) - In the wake of Cadia's fall during the 13th Black Crusade, the Great Rift thunders into being, reality bursting open like the stitches of a weeping wound to spill Warp-stuff into the galaxy. Plague Fleets strike all across the Imperium, spilling from the roiling Warp Storms of the Noctis Aterna to spread misery and decay.The Plague Wars (Unknown Date.M42-ca. 111.M42) - As the Blackness settles across great swathes of the Imperium, Chaos Cult activity and recidivist uprisings lead to the daemonic infestation of several prosperous star systems to the galactic north of Ultramar. Under the influence of Mortarion, these worlds fall entirely into Nurgle's grasp and become the "Scourge Stars," a feculent fortress for the servants of the Plague Father within realspace. It is from these suppurating staging posts that Mortarion will launch his campaigns into Ultramar in what will become known as the "Plague Wars."Rain of Filth (Unknown Date.M42) - During the siege of Godorian -- a world unlucky enough to be within light years of the Scourge Stars -- squadrons of Plagueburst Crawlers lob their shells in high parabolas. The diseased munitions slam down on manufactorum stack-vents and spill their filth in the Godorian labour furnaces to create giant, toxic plague censers. The resultant smog clouds drive the Imperial defenders into the open, easy prey for the guns of the Death Guard.Warzone Ultramar (Unknown Date.M42) - Mortarion's long-awaited invasion of Ultramar begins, initiating the Plague Wars. Sepsis cohorts of every Plague Company join the fight, with the 2nd, 3rd and 7th Plague Companies deploying in almost their entirety. Marching alongside daemon Tallybands, corrupted Renegade Knights, Traitor Titan Legions and countless warbands of Renegades, Chaos Cultists and turncoat Astra Militarum, the grotesque armies of Nurgle force the beleaguered defenders of Ultramar back step by bloody step.Unholy Endurance (Unknown Date.M42) - WAAAGH! Badsmak overruns a score of worlds to the galactic west of the Scourge Stars, forcing Mortarion to deploy numerous vectoriums to counter its wrath. During the campaign's pivotal battle on Krug's World, Warlord Badsmak himself leads a headlong charge against the outnumbered Death Guard. Death Guard Lord Fulgous the Bloated orders an immediate advance into the teeth of the Greenskin assault, calling down Plagueburst Crawler fire upon his own position. Weathering the pounding ordnance through a mixture of resilience and sorcery, the Death Guard draw the Orks into an explosive meat grinder. Plaguespitters dissolve wave after wave of the enemy hordes. Noxious Blightbringers toll their tocsins of misery again and again, driving the Greenskin Weirdboyz insane and spreading despair through the ranks. Finally, Badsmak and his surviving Boyz flee in abject terror, only to be annihilated by the Plague Marines' pursuing fire.Gifts of Nurgle (Unknown Date.M42) - On the Industrial World of Drogensul, several vectoriums of the 1st Plague Company meet stiff resistance from Imperial defenders. Death Guard drop ships make repeated passes over the industrial fortress-factories, dropping spiked iron cubes the size of hab units that crash down in the streets and manufactoria. Disease radiates from these rusting monoliths, and the Imperial defenders waste no time in setting charges to destroy them. The true horror of the Death Guard plan is revealed when the charges blow, rupturing the cubes and allowing the tightly-packed Poxwalkers inside to spill from the wreckage. Within solar days the Walking Pox is rife throughout the fortress-factories of Drogensul. Only then do the Plague Marines of the 1st Plague Company return to finish the fight.In the Maw of the Storm (Unknown Date.M42) - As Warp Storm Fomori engulfs the world of Danasar, Typhus duels -- and humbles -- Huron Blackheart atop the ruins of the Endless Spire. He leaves the Tyrant of Badab alive as an abject lesson not just in Nurgle's might, but also of his generosity.The Siege of Bellisos (Unknown Date.M42) - Much of the 3rd Plague Company find themselves besieged within the ruined husk of Hive Arkturon on the world of Bellisos. Led by Inquisitors of the Ordo Malleus, a huge force of Astra Militarum, Adepta Sororitas and Imperial Knights hammer the Death Guard positions day and night. Yet between the Death Guard's resilience and the screaming volleys of Plagueburst Mortar shells that are fired in return, it is the besiegers who find their forces ground down, and their warriors riddled with sickness. By the time the Death Guard launch their breakout assault, few of the attackers have the strength remaining to deny them victory.Battle of Bosphodia (Unknown Date.M42) - Vectoriums of the 5th and 6th Plague Companies engage in a naval battle with Craftworld Saim-Hann and its fleet around the moons of Bosphodia. Before they are driven off, the Death Guard successfully board the Craftworld and spread their corruption through the territory of Wild Riders clan Sylthach. In desperation, Saim-Hann's Seer Council orders Ghost Warriors to cut that part of the world-ship away with weapons fire. So devastating is the despair felt in that moment by the Aeldari that it conjures Nurgle daemons into the Waystones of the surviving Sylthach clan members, possessing them and transforming them into aberrant, insectile half-breeds. Soon enough, tales of spiteful, Chaos-tainted Aeldari Corsairs are prevalent throughout the Paragos Sub-sector and beyond.The Greyfax Gambit (Unknown Date.M42) - Having noted the fanatical obsession the Death Guard hold for the number seven, Inquisitor Katarinya Greyfax applies her suspicions to the battle for the Shrine World of Dortwyr. Launching their final assault on the seventh hour of the seventh day, the Death Guard pursue a baiting force of White Scars Primaris Astartes straight into the firing lines of seven Deathstrike Missile Launchers. The resultant rad-conflagration obliterates the Death Guard presence upon Dortwyr entirely.The Pristine Rotting (Unknown Date.M42) - After enduring solar months of filth and indignity in battle against the Putrid Choir, the Astra Militarum's 14th Volpone Bluebloods can take no more, and beg Nurgle to spare them from the corruption. The Plague God answers, rendering them forever gleaming and pristine, except for every seventh soldier amongst them. These unfortunates endure all the disease and pestilence their comrades should have, bloating into dirt-smeared, infectious spawn whose forlorn wails and wretched stench drives the rest of the regiment mad with guilt and horror. The Bluebloods turn their guns on their former comrades before throwing in their lot with their Death Guard tormentors.
