"Sow the seeds of damnation and I shall reap the souls of the tainted."

— Modus Executus

The Eversor Temple is possibly the most gruesome of the many temples that train Imperial Assassins for the Officio Assassinorum. The Eversor Assassins specialise in shock and terror tactics, instilling fear of Imperial retribution into the hearts and minds of all who hold positions of power in the Imperium of Man.

Often in the employ of the Imperial Inquisition's Ordo Malleus, Eversor Assassins are used to solve the problem when the indelible taint of Chaos is believed to have spread throughout the ruling elite of an entire Imperial Adepta or planetary government.

Whilst the more overt forces of the Ordo Malleus like the Grey Knights Space Marines may face the daemonic minions of a Chaos Cult or Chaos Space Marine warband on the battlefield, the Eversor will operate behind enemy lines and eradicate the infection at its source.

An Eversor Assassin rarely has just a single target. His mission will be to rip the heart out of the Chaos insurgency, wreaking havoc and destruction. Such brutality ensures that the Heretics are totally cleansed and that no would-be successors may take over. The sheer terror left behind in the wake of an Eversor Assassin's onslaught ensures that none will dare to oppose the will of the Imperium again.

The Inquisition's Ordo Hereticus has also been known to make use of Eversor Assassins from time to time. The Ordo Hereticus uses Eversor Assassins to eliminate the entire top echelons of Imperial Adeptas or planetary governments that are believed to have become heretical or turned against the will of the Emperor.


"Fear me, for I am your apocalypse."

Dictatus Eversor

An Eversor Temple Assassin.

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.


An Eversor Assassin finds his target

An Eversor Assassin has undergone a varied regimen of cybernetic and genetic augmentations to transform them into the ultimate killers. Additionally, the Eversor Temple has long made use of a special cocktail of combat enhancement drugs that are designed to instill a psychotic rage in its Assassins and to further enhance their physical capabilities to the point that it strains even their enhanced physiologies.

As a result, one of the first genetic enhancements made to an Eversor Assassin is to strengthen their immune systems beyond the human norm so that they can survive the sheer toxicity of the combat drugs they are constantly infused with.

Unfortunately, these drugs are also usually highly addictive and if the infusions are stopped, the Eversor Assassin will likely die from the agonising withdrawal symptoms. Additionally, the drugs will also dramatically shorten the Assassin's lifespan if he was allowed to remain conscious continually.

To deal with these difficulties, all Eversor Assassins are kept in cryo-suspension at all times between missions, and are only revived once they are needed for their next assignment. Eversor Assassins are kept in cryo-stasis aboard very special, and very secret starships and space stations that are placed all across the Imperium in highly-secure locations and kept on constant alert.

Only when a direct order is received from the High Lords of Terra through the Grand Master of Assassins of the Officio Assassinorum that provides a new assignment for an Eversor Assassin are the Temple's operatives awakened.

An Eversor Assassin about to be released from cryo-stasis

Once a mission has been assigned, an Eversor Assassin is transferred from his cryogenic crypt into a specially-designed one-man Drop Pod. The Assassin remains in stasis this entire time, while direct cybernetic neurolinks within the pod feed all of the relevant mission details directly into his neural cortex.

When the Temple's starship has come out of the Warp near the target planet, the Drop Pod's fully-automated systems begin to awaken the Assassin from stasis and to prepare his body with the necessary suite of combat drugs that best fit the mission profile. By the time the Drop Pod reaches the surface of the target world, the Eversor Assassin has fully awoken and been equipped to carry out the operation.

Due to the use of cryo-suspension to keep its Assassins alive, an Eversor Temple Assassin usually has no idea how much time has passed in the galaxy since he or she was last awakened to perform a mission, which could be a few solar decades or even Terran centuries.

For the Assassin, only moments have passed since they completed their last assignment and they emerge completely fresh and entirely focused upon carrying out their next objective, which is the only way to even begin to satiate their raging, psychotic bloodthirst.

In the early days of its existence during the Great Crusade and the Horus Heresy, when it was still known as the Eversor Clade rather than the Eversor Temple, the organisation maintained a major cryogenic iso-storage facility for its Assassins in the frigid Aktick (Arctic) northern polar region of Terra that was located deep beneath the glacial ice.

The Assassins were kept in their frozen dormant state in conduits filled with super-chilled methalon gas. The facility was maintained, as the Eversor starships and space stations are at the present, by members of the Temple's staff known as "technologians."

In many ways an Eversor Assassin has more in common with a living bomb than with a human operative. Rather than taking out a single target like the other Officio Assassins, an Eversor Assassin is usually employed to clear a large number of targets in a short amount of time.

In essence, Eversor Assassins are one-person special forces units. In fact, because of the amount of ability-enhancing drugs running through his or her body, when an Eversor Assassin is brought down and killed in combat, the drugs will react violently to the metabolic onset of death and cause the Eversor's corpse to explode, providing a final opportunity for the Assassin to kill the enemies of the Emperor.

In order to act so efficiently, an Eversor Assassin is fielded with a wide variety of weapons and combat tools, including a weapon known as an Executioner Pistol that can fire neuro-toxin-coated needles as well as explosive bolts like a Bolt Pistol, powerful Melta-bombs for destroying tanks and heavy doors, and a potent chemical cocktail of drugs that gives the Assassin incredible reflexes, enhanced durability and survivability and a single-minded rage to kill his targets.


The Eversor Temple Assassin, Sylas Torq, arrayed in his deadly panoply of death

  • Synskin Bodyglove
  • Executioner Pistol - An Executioner Pistol is a brutal blending of Bolt Pistol and Needler, able to switch between mass-reactive bolts and toxic darts at the touch of a button. This lethal fusillade has felled countless unlucky victims, their armour cratered and blasted open, even as their nerves sizzle with neurotoxins.
  • Neuro Gauntlet - A truly vicious weapon, an Eversor's Neuro Gauntlet ensures that their very touch is death. When the needled fingers of an operative's exoskeletal glove are plunged into the enemy's flesh, it delivers a massive dose of neurotoxins that kills the victims horrifically in a matter of seconds, though the poisons have little effect on creatures of the Warp like daemons and are best used on other humans or certain xenos.
  • Power Sword - The blade of an Eversor's sword is enveloped in a molecular dissonance that tears victims apart on an atomic level. Fashioned for an individual Eversor alone, the weapon's superdense core weighs thrice that of any comparable sword. Thanks to an operative's stimm-enhanced strength, it allows their every blow to hit like a wrecking ball, with no appreciable encumbrance whatsoever.
  • Melta Bombs - The Eversor Assassin is also always equipped with a variety of powerful Melta-bombs capable of destroying armoured vehicles and destroying structures. The bombs can also be used as a suicide weapon in extreme circumstances.

Notable Eversor Assassins

  • Sire Eversor - The founder and first Director Primus of his clade, Sire Eversore was the namesake and founder of the Eversor Temple. He was the foremost psychotic assassin of his age. He, along with the other founders of the various Assassin clades that would eventually evolve into the Assassin Temples, was present on Mount Vengeance. He and his fellows swore a pact in the shadow of the Great Crusade, an oath that breathed life into the creation of the Officio Assassinorum. The newly created clades hunted down the enemies of the Emperor through stealth and subterfuge, establishing the fact that there was no safe place in the galaxy to hide from the Emperor's justice.
  • "Ganimus" - The assassin designated as "Ganimus" was an Evesor Clade Assassin which was active during the era of the later Great Crusade and the Horus Heresy. What littlte information available certify that Ganimus acted on direct orders of Malcador the Sigilite, the Regent of Terra when he was despatched to his birthworld of Proxima Apocryphis. There, he was charged with the murder of the local Planetary Governor, Chravius Blumolotov, after his world had openly declared for the Traitor Warmaster.
  • "The Garantine" - The so-called Clade Eversor Assassin known only as "The Garantine" was a Nihilator of Clade Vindicare who was ranked as an Epsilon-dan, the senior-most rank of his order, and was active during the Great Crusade and the opening days of the Horus Heresy. His original name forgotten, the operative codenamed "Garantine" was so-named because it was said he hailed from the Garant Span, an Oort Cloud collective on the near side of the Perseus Null. A natural psychotic, he had killed everyone on his home asteroid, and all this as a child barely able to read. It was no wonder the Clade Eversor had been delighted to take ownership of him. The Garantine was dispatched with the first-ever Imperial Execution Force composed of Imperial Assassins from every clade, who were attempting to assassinate the Traitor Primarch Horus upon the world of Dagonet. Ultimately, their assassination attempt failed and all the Assassins were slain by the Traitors.
  • Sylas Torq - Sylas Torq was an Eversor Assassin who had a reputation of ill-repute as a psychopathic killer. Thus, he was chosen as part of an Execution Force to take part in the vital mission in the Achyllan System during the 13th Black Crusade. The Sorcerer Lord Severin Drask, of the Crimson Slaughter Renegade Chapter, was intent on utilisng an ancient Chaos construct known as the Temples of Shades to extinguish the system's primary star and create a new Warp Rift that would extend from the Eye of Terror and all the way towards Terra itself. As the Crimson Slaughter led a series of diversionary, murderous raids throughout the Segmentum Obscurus to distract the Imperial forces from their intended target, Drask led a pre-planned raid upon the barely defended world of Achyllan Prime, and quickly swept aside all resistance from the Cadian Astra Militarum Regiments. During the ensuing battle, thanks in no small part to the efforts of Primaris Psyker Lunst Cataboldine, he was able to pull the plans for the Achyllan Atrocity from the Sorcerer Lord's mind, and sent a desperate astropathic message through the Warp. Though Lunst died in the process, the Imperium learned of Drask's ultimate plan. To counter this threat, the High Lords of Terra decreed that an Execution Force would be despatched to assassinate Drask and foil his plans. Launching 'Operation Deathblow', the Imperium sent an Execution Force comprised of Eversor Assassin Sylas Torq, Callidus Assassin Klara Rhasc, Culexus Assassin Noctus Kord, Vanus Assassin Kurei Adamta and Vindicare Assassin Viktor Zhau to carry out this vital mission. The Assassins successfully landed upon Achyllan Prime, and were able to locate the Sorcerer Lord's whereabouts, but had to fight wave upon wave of Daemons, Cultists and Chaos Space Marines in order to reach Drask in the Temple of Shades. In the ensuing battle, it was Sylas Torq who sacrificed himself in order to achieve their objective, by blowing himself up and killing the Sorcerer Lord. Only the Vanus Assassin Adamta survived the mission.
