Soul Drinkers - Notable Campaigns: War of the Beast (544-546.M32) - The Soul Drinkers joined with the other Imperial Fists Successor Chapters into a Legion as per the Last Wall Protocol at the behest of Koorland when Terra came under threat from the assault of the Orks under the command of The Beast. Chapter Master Euclydeas was given command of a third of the combined fleet of the forces gathered to protect Terra. After the conflict, the Soul Drinkers contributed a portion of their strength to rebuild the Imperial Fists Chapter.Wars of Apostasy - Terran Crusade (378.M36) - When the insane Ecclesiarch Goge Vandire I, 361st Master of the Administratum and Lord Protector Spiritual of the Imperium of Man declared himself both Ecclesiarch and High Lord of the Administratum, he began the now infamous Reign of Blood, a time of terror in which millions died due to his megalomaniacal paranoia and bloody pogroms. Vandire's ambition had grown within him until it surpassed the bounds of human logic and became insanity. Vandire was the propagator of a moral disease, an arch-heretic, an icon of sin. He had to be destroyed. The Adeptus Astartes had stood aloof from Vandire's reign, caring nothing for temporal power. They had no interest in ruling the Imperium themselves, but enough was enough. The Fabricator General of Mars had sent Titan Legions and tech-guard to bring Vandire to task. Regiments of the Imperial Guard, those not loyal to Vandire, had rallied to their banner. Then the Astartes had joined them, and Vandire's fate had been sealed. Together with their Primogenitor Chapter, the Imperial Fists, two other Chapters -- the Fire Hawks and Black Templars -- the Martian Tech Guard and the 914th Sevayin Reavers Imperial Guard Regiment, the Soul Drinkers took the fight to Terra itself. The Soul Drinkers, Fire Hawks and Sevayin Reavers were part of the thrust into the southern region of the Ecclesiarchal Palace. This was primarily a diversion, as was the capture and fortification of the Greigorian Basilica by the Imperial Fists. The commanders of the assault believed that the killing blow would come either from the westwards attack by the tech-guard and Titans of the Adeptus Mechanicus, or the drop-pod attack the Black Templars would launch on the Cathedral of the Emperor Deified. The diversionary attack was intended to draw the palace defenders away from the cathedral and the Ecclesiarch's audience chamber, the most likely locations of Vandire himself. The siege was ended with the death of Vandire at the hands of the leader of the High Lord's personal bodyguards -- Alicia Dominica of the Brides of the Emperor -- after learning the awful truth of Vandire's reign.Keprian Reclamation (Unknown Date.M42) - The Keprian Reclamation was a campaign of the Indomitus Crusade waged by the resurrected Ultima Founding Soul Drinkers. Captain Quhya's 3rd Company was tasked to reclaim the world of Kepris from the Chaos Cult forces of the Heretic preacher Yeceqath. The world was a prime target for the crusade as Kepris was home to a collection of relics precious to the Imperial Creed. Their reclamation would prove to be a much-needed psychological victory for the forces of the Imperium. Unfortunately, the unorthodox tactics used by the Soul Drinkers during the successful campaign to reclaim Kepris and its precious relics drew the ire of the Inquisition, whose agents revealed to the Soul Drinkers the truth of their forebears' treachery and corruption by Chaos. This revelation has shaken the reborn Chapter's Primaris Marines, who now find themselves seeking to atone for the sins of their namesakes.
