Eversor Temple - History: The Eversor Clade which evolved into the Eversor Temple can trace its origins back to the time of the Great Crusade in the late 30th Millennium. The Emperor's Regent and closest advisor, Malcador the Sigillite, who served as the first Grand Master of Assassins for the Imperium, first formed the Officio Assassinorum with six other individuals at Mount Vengeance who had sworn to eliminate all enemies of the Emperor by any and all means necessary, including stealth and assassination.Each of these six individuals became the founder or "Director Primus" of a clade of assassins that actively operated to remove threats to the Great Crusade's success when direct military operations were impractical or too costly. The Eversor Clade was created by Sire Eversor, whose clade became well-known for the brutality with which it carried out its operations.When the Horus Heresy began, the Grand Master of Assassins ordered that all the clades of the Officio form the first known Execution Force of Assassins drawn from every clade to eliminate the Warmaster Horus before his rebellion and civil war could substantially damage the Imperium.Among the Assassins who would become a part of this force was the Eversor Clade member known only as "The Garantine" who had been accidentally awakened from stasis at the Eversor facility in the Aktick on Terra. Ultimately, this mission would fail and all of the Assassins involved would be slain.In 536.M32 the then-Grand Master of Assassins Drakan Vangorich assassinated all of the sitting High Lords of Terra in an event that became known as the Beheading and then fled to an Officio Assassinorum temple. The Space Marines of the Halo Brethren, Imperial Fists and Sable Swords responded to this brazen power grab by launching a raid on the temple, where they battled a force of one hundred Eversor Assassins. Only a single Astartes survived the skill of the Assassins to bring the Emperor's justice to Vangorich.Another notable incident was the Slaughter of Clan Mackenzie that occurred during an unknown period of Imperial history. The ruling family of Dumroamin VI in Segmentum Ultima was the Clan Mackenzie, an ancient colonial family, led by Grand Duke Fraser Mackenzie.It became evident that the Clan Mackenzie were financing pirate raids on their neighbours, paying for stolen goods taken from the rival Mining Worlds of Rouan and Nearly-There. An unnamed Eversor Assassin was dispatched to wipe out Grand Duke Mackenzie and all his living relatives during the Grand Hootmamay (a local Heretic festival), which was held every local summer.The Eversor succeeded in killing all 317 members of the Clan Mackenzie (the youngest being three weeks old, the eldest 142 years of age), although at times the Assassin was forced to resort to various improvised weapons to complete the daunting task, including a silver soup spoon and a butter knife.During the Taros Campaign in 998.M41, an Imperial campaign to retake the Mining World of Taros in the Segmentum Obscurus from the forces of the T'au, the Imperial forces requested the aid of the Officio Assassinorum through the use of a priority astro-telepathic message after they discovered the location of the T'au Fire Caste's headquarters on the arid planet.An Assassin of the Eversor Temple was tasked with the mission of assassinating the T'au commander, Shas'O R'myr, to disrupt the Tau command in the campaign. The mission was code-named Operation Deathblow. The Ethereal Aun'Vre who was directing the T'au operations on Taros was also located within the headquarters and his death would be a major blow to the ability of the T'au Fire Warriors to carry out combat operations, although this was a secondary objective.The Assassin's transport ship Son of Jucha successfully delivered his stasis pod to the Imperial flagship Righteous Blow after evading the blockade erected by the T'au Navy around the Taros System. The Assassin was released onto Taros' surface by a Drop Pod expelled from the flagship.The Assassin successfully penetrated the T'au's hidden command centre and detonated his suicide Melta-charge, killing himself and the Ethereal as well as destroying the entire command centre.However, the mission was not an unequivocal success because Shas'O R'myr was already outside leading his bodyguard against the Imperial attack and was not caught in the Assassin's blast.
