Note: This article discusses material that was once considered canon but whose canonicity is now questionable.
They are created from Human victims that are abducted by the Necrons, and bear the "Pariah Gene" that severs the bearer completely from the Warp; effectively making them both soulless and immune to the effects of all psychic abilities.
These troops apparently did not meet the requirements or expectations of the Necrons who created them, as they are no longer normally fielded as part of a Necron army.
In general, Pariahs, also known as psychic "Blanks" in the Imperium, do not live long as the feelings of unease and distaste they generate among others means they have few friends and many enemies.
Pariahs are very rare in the galaxy since perhaps only one person on an entire world will be a carrier of the gene in every Human generation. Pariahs are often used by the Inquisition and the Ordo Hereticus against witches and Renegade psykers and the Sisters of Silence are wholly composed of female Pariahs.
Necron Pariahs are captured Human Blanks who have undegone the ancient Necron biotransferance process so that their sentience is now housed within a new cybernetic body forged from the living metal called necrodermis by the Necrons.
Their minds are soon enslaved to the will of the Necrons much like the more common Necron Warriors, as their new bodies drain their abilities to feel any emotion or pleasure.
The Eldar have hinted in the past that the Pariah Gene was deliberately engineered by the Necrons into the ancient primate population of Old Earth millions of Terran years ago in the hope of eventually creating a biological anti-psychic weapon.
Certainly the Pariahs have proved to be a potent weapon for the Necrons against the Imperium of Man since they emerged from the hibernation of the Great Sleep.
The truth of this contention remains unknown to the Imperium's savants at this time.
Necron Pariahs normally operate in squads composed of 4 to 10 of these monstrosities. Pariahs radiate a constant sense of palpable menace and horror to those around them, blotting out all psychic emanations and infusing those nearby with the sense of their own mortality. In this way, Pariahs embody the ultimate horror of the Necron threat to the galaxy.
However, the Necron Pariahs possess one known weakness; they lack the powerful regenerative ability of true Necrons due to their Human roots and still retain many of their fleshy Human organs encased within their necrodermis shell, making them far more vulnerable to weapons fire than their immortal counterparts amongst the former Necrontyr.
Wargear & Abilities
Pariahs have an extreme detrimental effect on the psychic powers of any psykers they come into contact with.
Pariahs continuously radiate an unnatural aura as a result of their soullessness that has a terribly unnerving effect upon their enemies, but especially for psykers who can become incapacitated by their sheer presence.
No psychic abilities will have any effect upon a Necron Pariah.
Notable Necron Pariah
- Thomas Macabee - Prior to his transformation, Macabee was an archeology professor and prominent Gue'vesa on the Tau world of Kronus. However, when his archaeological expedition to explore the Necron ruins on Kronus unknowingly opened the entrance to the Necrons' subterranean stasis tomb complex, the expedition awoke those ancient warriors. Most of the team died then and there, but Macabee was taken by the Necrons and remade as a Necron Pariah as he was found to bear the rare Pariah Gene. In the ensuing campaign of extermination waged by the Necrons against the other factions on Kronus, Macabee, now bereft of any will of his own, would act as an adviser and spokesman for the otherwise-silent Necron Lord of Kronus.
