Black Wings - Notable Campaigns: The Sorrowful Pursuit (ca.118-418.M33) - Chapter Master Khardin Gol of the Black Wings Chapter and numerous lords of the Imperium were brutally murdered during the infamous Hour of Shadow, which plunged the world of Lorin Alpha into riot and madness. In the aftermath, the Black Wings pursued the Chaos Renegades known as The Tenebrae into the Veiled Region beyond the edge of Imperial space seeking revenge. Three standard centuries later, a single damaged strike cruiser returned from the outer void bearing a handful of survivors. They would speak of what they had endured to none save the agents of the Ordo Malleus of the Inquisition. The Chapter was slowly rebuilt to full strength from its reserve stocks of gene-seed over several solar decades and swore an eternal oath of vendetta against The Tenebrae and its nightmarish works.Cleaving of the Black Wings (700.M35) - Five entire companies of the Black Wings Chapter renounced their vows of service to the Emperor, turning upon their brethren at the height of the Chapter's centennial Ritual of Remembrance. The battle that followed saw hundreds slain and several strike cruisers destroyed, and much of the Chapter's fortress-monastery laid to waste before the Renegades were finally driven off. The cause of this base treachery was never fully ascertained, although some came to suspect a deep-seated Warp taint that took root in the Chapter's soul centuries before, slowly twisting the Chapter's rituals and doctrines. The Black Wings Chapter changed its livery in the wake of this shameful betrayal, painting half of its crimson armour black until such time as their Renegade brethren are hunted down and made to pay for their heinous crime.The Martyred Sons (416.M37) - Inquisitor Lord Antonius Coil of the Ordo Malleus discovered the current location of the nomadic Hell-Forge of Sarum while conducting Exterminatus against the Warp-tainted Hive World of Golconda IX, and moved to see it destroyed at last. Along with warships commandeered from Battlefleet Reductas and several Militarum Tempestus regiments, he mobilised the aid of three entire Space Marine Chapters: the Brazen Claws, the Sons of the Raven and the Celestial Guard, to strike deep into the perilous Golgotha Wastes against this nightmarish thorn in the Imperium's side. Within sight of the baleful world, the Imperial fleet was ambushed on all sides by the pale warships of the Warp Ghosts and Renegade Black Wings Chaos Space Marines, and the horrific Daemon Engines of their Dark Mechanicus allies of Sarum. In the brutal seventeen-solar-hour void battle which followed, the Imperial fleet was encircled and slowly torn to pieces both from without and from within as Daemons ripped open passageways into realspace deep onboard the stalwart vessels. Only the Chapter fleet of the Brazen Claws broke free from the trap without crippling losses, while the Human contingent of the Imperium's strike force was annihilated to the last. The ravaged Celestial Guard would take nearly a standard century to rebuild from its grievous losses from its stores of gene-seed, swearing bitter vengeance against the Warp Ghosts. The fleet-based Sons of the Raven Chapter, not one of whom escaped the deadly trap, was declared martyred and the great Bell of Lost Souls in the Imperial Palace's Tower of Heroes on Terra tolled to mourn their passing.Garanhir Rebellion (649.M40) - A World Eaters warband, under the command of the notorious murderer Dhalahk, launched a mass incursion against the world of Garanhir, intent upon spilling the blood of the Emperor's faithful in an unprecedented act of veneration of the Blood God. Expecting to find Garanhir unprepared for attack and ripe for the slaughter, what the Khornate Berzerkers actually encountered as they charged from the assault ramps of their drop craft was a world already claimed by war, the populace armed and led by the famously militant Inquisitor Malphas Kroh. Kroh had employed a precognitive-coven of psykers to predict the World Eaters' assault, his punitive intervention sparking a general uprising which he put down a mere solar day before the Berserkers' attack. The World Eaters found the Inquisitor and a large force of Grey Knights, as well as Dark Swords and Black Wings Space Marines, waiting for them. Battle was joined without delay, and while the warriors of Dhalahk made a lethal account of themselves, they were ultimately slain, the entire warband cut down by the defenders, though not without significant cost to the Imperium's forces.
