Officio Assassinorum

==Summary==
The Officio Assassinorum is the Imperium's highly secretive agency designed to push individuals beyond normal human limits, turning them into some of the deadliest killing machines ever conceived. Even the most hardened warriors fear the Assassins, and rightly so. Each Assassin is rigorously trained in his or her temple's ways, perfecting the art of killing. All members of the Officio Assassinorum are capable of operating on their own behind enemy lines, with little to no assistance, almost indefinitely. Even the mightiest warlords can be felled and the greatest armies thrown into turmoil by these individuals, all without ever alerting a single soul to their presence, while even the thickest armour and strongest body guards are meaningless against the silent death delivered by the Emperor's Knives.

This also applies to weapons and other objects that possess these properties), Statistics Reduction (The presence of a Culexus Assassin reduced the "terrifyingly powerful" Dread Gestalt's strength to that of a mere newborn)
</tabber>
Attack Potency: Building level physically (Body enhanced to superhuman degrees, should at least be on par with an average Space Marine). Exitus rounds ignore durability (Hellfire rounds completely destroy matter, Turbo-penetrator rounds punch through tanks better than Melta weaponry and tear through the target's molecular structure, and Shield-breaker rounds use a combination of science and arcane wards to easily break through Warp-based, magical, supernatural, and reality-warping defenses) | Unknown, up to Building level (Though weaker, is capable of contending with an Eversor for short periods of time with supreme effort as well as knocking one out with a well placed blow. Poison Knives are able to penetrate the bodyglove of an Eversor). The Neural Shredder and C'tan Phase Sword ignore durability. | At the very least Building level (Often sent to shred foes which even Space Marines cannot overcome. An Eversor berserker was the only one able to hold his own against the rogue Maerorus Assassin known as Legienstrasse, who was capable of easily fending off and overpowering Darnath Lysander, two of the most elite squads in the Imperial Fists, the Emperor's Champion, a squad of Scout Snipers, and two Assassin Grand Masters, simultaneously), far higher with Bio-Meltdown (Upon death, an Eversor Assassin will explode in a Bio-meltdown. These explosions are much more powerful than the Eversors themselves, being capable of instantly killing foes superior to the assassin. A relatively average Eversor was able to kill 7 space marines with one explosion, and the explosion of one of the strongest ones dealt fatal damage to Legienstrasse while nothing else could). All weapons ignore durability to an extent (Executioner Pistol injects targets with deadly poisons, Neuro Gauntlet fills foes with fatal doses of chemicals and toxins, Power Sword disrupts the target's body on an atomic level) | Building level physically (Should be comparable to a Vindicare), far higher against supernaturally powerful opponents (Culexus Assassins can drain the power of those with a strong connection to the warp, weakening their foe and amplifying themselves. Several of their abilities work better on opponents stronger in this regard, allowing them to defeat Greater Daemons and Daemon Princes with ease)
Speed: At least Hypersonic, likely higher reactions (Most Assassins are shown to be similar in speed, Much better reactions than even the majority of Space Marines), Exitus rounds likely fire at Relativistic+ speeds (Capable of hitting other assassins, A Vindicare was able to shoot a target on the moon through his eye, all while standing on top of a building on the planet that the moon orbited. However, due to having to obey traditional laws of physics, the bullets cannot travel at lightspeed or beyond, unlike something such as a C'tan shard, which is immune to natural laws) | At least Hypersonic, likely higher reactions reactions (Most Assassins are shown to be similar in speed, Much better reactions than the majority of Space Marines) | At least Hypersonic, likely higher reactions reactions (A skilled Eversor was able to fight Legienstrasse, who was overwhelming Lysander) | At least Hypersonic, likely higher reactions (The Culexus known as Vaedrex was able to surprise a Daemon Prince and slay him before he could recover. Daemon Princes can easily fight on par with and overwhelm the most experienced Space Marines)
Lifting Strength: Unknown
Striking Strength: Building level (Even the weakest Assassins can break through steel and ceramite with their fists) | Unknown, up to Building level (One was capable of knocking out an Eversor with a kick, while trying not to kill the Eversor) | At the very least Building level (Can beat enemies to death that Space Marines cannot overcome. An Eversor Assassin was capable of matching the physical blows of Legienstrasse) | Likely Building level (Though all attacks ignore durability, should not be physically weaker than a Vindicare)
Durability: Building level (Synskin can absorb bolter fire) | Unknown, up to Building level (Synskin can absorb bolter fire, can endure attacks from an Eversor) | At the very least Building level | Unknown. At the very least Building level (Synskin can absorb bolter fire. Etherium makes non-conventional attacks pass right through the Assassin as if he wasn't even there. Culexus Assassins are still vulnerable to basic attacks, though they are incredibly difficult to hit, as they only appear as ephemeral blurs in their foes' peripheral vision)
Stamina: Superhuman (A Vindicare Assassin was able to remain motionless in the same spot for six entire years while waiting for his target, killing said target within half a second once it finally arrived)
Range: Likely hundreds of Thousands of Kilometers with Exitus Rifle (Hit a target on the moon while still on the planet), likely Hundreds of Meters with Exitus Pistol | Standard Melee Range with Phase Sword, at least Tens of Meters with Neural Shredder and Poison Blades | Standard Melee Range with Power Sword and Neuro Gauntlet, likely Hundreds of Meters with Executioner Pistol | Standard Melee Range, at least Tens of Meters with the Animus Speculum
Standard Equipment:
Synskin: All Assassins sprays their bodies with a synthetic coat of black skin. This protective covering not only absorbs damage to the Assassin, but can also be used to conceal weapons, enhance physical prowess, and provide the Assassin's body with oxygen and metabolic boosters.
Intelligence: All Assassins have Genius level intellect, as they are able to operate almost any technology, navigate around the galaxy on their own, memorize the entire history of the Imperium along with the function and inner workings of all its organizations, speak all Imperial languages, understand every single aspect of human anatomy as well as every discovered aspect of xenos anatomy, etc.
Weaknesses: None notable | Certain absorbed substances can have adverse effects on the Assassin | Eversor Assassins have little concern for their own lives, some poison was noted as being able to trigger the Bio-Meltdown before killing the Eversor | None notable
Note: The stats for Venenum and Vanus Assassins have not been included, as Assassins from those two temples are not fighters, and thus little is known of their combat capabilities.
==Temples of the Officio Assassinorum==
<tabber>
|-|Vindicare Assassin=
Vindicare Temple: Assassins of the Vindicare Temple are cold, calculating killers who have elevated their marksmanship to such heights that it has become an art form. With a single bullet, they can bring a pathetic death to those who defy the Imperium, turning a roaring rebellion into a meek crowd easily herded back into place. This is due in no small part to the Assassin's superhuman aim. Vindicare Assassins are always in high demand, as they can effortlessly pick off enemy leaders from insane distances, regardless of the surrounding conditions. Even the threat of a Vindicare watching from the shadows has been enough to make countless upstarts think twice, giving up on their schemes against the Imperium before ever even putting them into motion.
Assassins of the Vindicare Temple carry the following wargear:
* Exitus Rifle: An absolute marvel of Imperial technology, each individual gun is built specifically for its wielder. The rifle is balanced and weighted so perfectly, it becomes an extension of the Assassin's own body when aiming and shooting. The advanced machine spirit housed within the weapon insures that it will never jam or misfire, ensuring the shot always lands exactly where it was planned.
* Exitus Pistol: Just like its larger variation, the Exitus Pistol is made specifically to fit an individual's needs. The Assassin will usually employ the pistol in the rare instances that his position is compromised, using it to blast enemies at close range while he makes his escape.
* Exitus Rounds: Perhaps even more stunning than a Vindicare's guns are the bullets used for such weaponry. The three individual types of rounds ensure the Assassin is prepared to take down any target, no matter the circumstance. Turbo-penetrator shells are segmented cylinders, each portion of which is tipped with a melta charge that activates with a staggered detonation to the last. Because of this, the bullet can punch through any armour, no matter its thickness or composition. Regardless of how well defended a foe thinks he is, a Turbo-penetrator bullet will cut through his defenses as if they were not even there. Then, there are Hellfire shells, which are filled with a wide mix of virulent chemicals and acids. On impact, the bullet explodes, showering the foe with a hail of microscopic needles which pump the chemicals into them. No matter how tough the matter seems, the acids within the shell will eat away at it, leaving nothing but a pile of black gunk. Finally, the Vindicare is armed with Shield-breaker shells, which include destabiliser cores capable of blasting through both physical and metaphysical defenses. Even incorporeal foes are not safe, as the runes inscribed on the shell allow it to make contact with the aetheric foes, blasting them into an explosion of dissipating ectoplasm.
* Spy Mask: Even amongst Mars' mysterious technology, the Spy Mask is one of the least understood. The device fits snugly around the contours of the Assassin's face, connecting with his cerebellum and feeding exact trajectories, atmospheric conditions, thermal imaging, and more into his field of vision. The Mask also allows the operative to see right through fog, smoke, and snow, while simultaneously using probability scripture to identify a target's weak points. Even a veteran Space Marine could not handle such a massive influx of information, but the Vindicare's mind processes it all with extreme ease. Additionally, the incredible device holds concentrated food and water cartridges, a motion-tracking Auspex, high-quality magnoculars which allow perfect vision for absurd distances, a photo-visor to render the Assassin immune to the effects of blinding tech such as Photon Grenades, a multi-channel communications sensor for secretly listening in on enemy conversations, a Vox-caster, Pict-recorder, and a Re-breather to allow the Assassin to survive even the most toxic environments in the galaxy.
* Blind Grenades: Simple but effective, these explosives allows the Assassin to temporarily blind any enemy who gets too close, while his Spy Mask renders him immune to the grenade's blinding effects, allowing him to put a shot through the enemy with his Exitus Pistol even as the flash goes off.
|-|Callidus Assassin=
Callidus Temple: The ancient Callidus Temple is unique in the fact that every single one of its Assassins is female, a trait attributed to the temple's particular style of assassination. The Callidus Assassins are the most subtle members of the Officio Assassinorum for a reason, as they are masters of disguise. A Callidus can take the form of anyone she pleases due to a drug known as Polymorphine being injected into her body; a substance which only seems to work to its fullest extent on women. This allows not only for some of the most effective assassinations imaginable, but also the opportunity to sow extreme paranoia and anarchy amongst the foe. Often times, a Callidus will not simply infiltrate the foe's headquarters and assassinate the leader, but also proceed to take his form, giving the enemy contradictory and detrimental orders, allowing the armies of the Imperium to wipe them out without hassle.
This tactic is not strictly limited to humans and similar beings either, as internal modifications can allow a Callidus to shift her form even more drastically, such as to the form of a Genestealer Hybrid. The prey of a Callidus Assassin is never truly safe, for the Assassin's shapeshifting also allows her to squeeze her body through pipes, cracks, and vents to get where she needs to go. Her control over her form is absolute, being able to accomplish anything from flattening herself under a door to swallowing her target whole.
Assassins of the Callidus Temple carry the following wargear:
* Poison Blades: Concealed on her person, a Callidus carries numerous needle-like blades, both incredibly slim and wickedly sharp. The Assassin's superhuman aim allows her to easily drive these through the tiniest weak points, be it a joint in armour, gaps in a scaly hide, or even through a victim's eyes. Each blade is coated in a lethal venom that can cause even the toughest foes to drop dead in seconds.
*Neural Shredder: An extremely rare and dangerous weapon often used by the Adeptus Astra Telepathica, the Neural Shredder fires a blast of energy that is fatal to virtually all living foes. Any being unfortunate enough to be caught in the weapon's sights will have their nervous system dismantled, their mind rended to nothingness, and be left as a slab of drooling meat. Though technically still alive, the foe's mind will be gone forever, and they will be stuck in an irreversible vegetative state until their body shuts down, for good.
* Phase Sword: Easily the most deadly of all weapons a Callidus carries on her person, the Phase Sword is a forearm-mounted blade of alien origin that is lethal to all it touches. The sword constantly phases in and out of reality in a frequency even more different than that of Warp-based weaponry. There is no blocking the Phase Sword, for it not only cuts through all that is physical, but also all defenses on a metaphysical level, as well.
* Death Card: Unlike all other weapons carried by a Callidus Assassin, the Death Card is purely an instrument of terror. After the Assassin has brought a swift end to her target, and provided there is enough left of said target, she will sometimes leave a psychoplas wafer on the body. For added effect, it will often be left between the gritted teeth or stiff, dead fingers of the corpse. When a living being discovers the body and makes contact with the device, it will spring to life, projecting a hololith of the victim's terrified face the exact moment before their death, complete with an audio loop of their agonised screams as the Callidus ended their life in some unthinkable way.
|-|Eversor Assassin=
Eversor Temple: Unlike the other temples, the Eversor Temple puts less of a focus on complete secrecy and stealth, and more of a focus on pure, primal terror. Eversor Assassins are often deployed when the taint of Chaos reaches a world controlled by the Imperium of Man. As opposed to sending a force such as the Grey Knights when a full-scale daemonic incursion breaks out, the Eversor will be dispatched to rip out the heart of the insurgency, quelling it before it can become more of a problem. Once behind enemy lines, the Assassin will track down the heretic leaders, slaughtering them in horrific and gory ways while the cocktail of chemicals flowing through his body fuels his inhuman rage.
After seeing the Eversor's handiwork, any potential successors of the cult are scared away, and the forces of Chaos seep back into the darkness from whence they came. Of course, Chaos worshippers are not the only ones to feel an Eversor's wrath, for the Assassin may be roused from his cryo-stasis to tear apart upstart xenos leaders as well, such as an up-and-coming Ork Warboss and his elite Nobz, or a group of Eldar Warlocks. Even in death, an Eversor Assassin strives to kill as many foes of the Emperor as he can, the chemicals in his body producing a catastrophic Bio-meltdown and annihilating anything unfortunate enough to be around him.
Assassins of the Eversor Temple carry the following wargear;
* Executioner Pistol: Each Eversor Assassin carries a deadly Executioner Pistol, designed to fire both explosive bolt rounds and toxic needle rounds whenever the Assassin so desires. With the touch of a button allowing him to switch rounds at insane speeds, an Eversor can blast open his enemies' armour before burning away their nerves with neurotoxins, all before they can properly process the Assassin's brutal assault.
*Neuro Gauntlet: On one of his hands, an Eversor wears a gauntlet with neurotoxin injectors in the place of fingernails. With even the lightest scratch, he can fill his foes with a fatal dose of hazardous chemicals.
* Power Sword: The Power Sword of an Eversor Assassin is covered in a molecular dissonance field that slices through his unlucky victims on an atomic level. Thanks to the superdense core and the operative's enhanced strength, every strike packs even more power than a comparable weapon normally would.
* Sentinel Array:This device allows the Eversor to process targetting information at ludicrous speeds, meaning even while running the risk of being overwhelmed, he will always be able to aim and fire to the best of his ability.
* Melta Bombs: An Eversor is never without a variety of Melta Bombs, allowing him to blow apart reinforced structures and reduce even the hardiest vehicles to slag. Under the most extreme circumstances, the Eversor may use all of his bombs as a suicide weapon, adding on to the force of his Bio-meltdown in order to achieve maximum potential damage.
|-|Culexus Assassin=
Culexus Temple: Members of the Culexus Temple are unique and terrifying, even among the ranks of the Officio Assassinorum. All Culexus Assassins are born with the Pariah Gene, an incredibly rare genetic defect that means, unlike all other sentient beings, the Assassin lacks any presence in the Warp whatsoever, making him effectively soulless. This trait is believed to have been inserted into humanity's ancestors countless years ago by the C'tan as an anti-psyker weapon, and the effect shows. Even to a regular person, being around a psychic blank is an uncomfortable and painful experience that can never be forgotten. However, to a psyker, the experience is unfathomably worse, as the psyker experiences unspeakable pain, mental anguish, and horrors they cannot fully comprehend.
On top of this, any psyker within the presence of a Culexus Assassin will have his powers disabled, whereas the blank's merest touch is enough to completely extinguish a sentient being's soul. Once a Culexus stalks onto the battlefield, psychic lines are severed, ancient and powerful magic fizzles out, and warping of reality is suddenly undone. Formerly powerful entities panic as the abilities they once thought omnipotent are erased, and the Culexus Assassin slowly treads closer with the crushing inevitability of death.
Assassins of the Culexus Temple carry the following wargear:
* Animus Speculum: The Culexus' ornate helm can function either as a dampener or amplifier of his powers depending on what the situation calls for. As the Culexus nullifies powers that twist and mold reality, users of such powers will find all their energy absorbed into the Animus Speculum, making the Assassin even stronger. While usually used to stifle the Pariah's presence as he stalks the battlefield towards his prey, it can also be used to project his horrific aura, even firing focused blasts of what can only be described as "negative Warp energy" back out; a technique absolutely devastating on all sentient beings.
* Etherium: A highly advanced nodal layer is built into the Assassin's synskin, shifting his body out of sync with reality. This renders him practically invisible to mortal and immortal eyes, as he appears absent in both the physical and spiritual planes while he moves through all obstacles and towards his kill.
* Psyk-out Grenades: All Culexus Assassins carry rare and exotic Psyk-out Grenades in order to even further enhance their effectiveness at killing wielders of supernatural power. Made from psi-refractive particles gathered from the Golden Throne, Psyk-out Grenades are effective on normal beings, and even more effective on abnormal ones. Sentient beings who do not make use of psychic or magical powers will simply lose conscious thought, making them easy targets. However, for those that make use of reality-bending abilities, the negative psychic energy from the grenades will cause their powers and abilities to fundamentally collapse and implode, destroying them from deep within their very soul all the way to their physical form.
