Untouchables

The untouchables are those humans who have less warp sensitive souls or none at all , granting them varying degrees of immunity to the warp’s effects and corruptions . They are somewhat of what enigma when it comes to how and why exactly is someone born in this state and what are their full capabilities.

Mudding the water further is centuries of imperial censorship and information distortion as well as the extreme rarity of untouchables in general. This has led to many terms such as nulls, blanks and pariahs arising and it is not known if they refer to different power levels or the same thing.

However Atlantis’ abundance of them has given us a rare chance to study them though research at the Departmento Nihlus is currently slow as it is still consolidating.

### Nulls

Nulls are generally those with weak or no souls at all and does not seem to be caused by a genetic quirk like the parish gene and happen through random chance. Theoretically nulls can be artificially created by removing a person’s soul, though this has not been tried yet.

While nulls generally cause discomfort and disgust to normal humans it is usually not severe enough to trigger aggressiveness . With psykers however all nulls (sans Sigma class ) cause physical and psychological pain with the psyker even possibly dying depending on how powerful the Null.

They range in abilities from being merely resistant to warp based attacks to completely nullifying the effects of the warp around them.

Nulls are classified as follows (from lower powered to higher ):

* Sigma : Sigmas are not actually nulls as they still have souls but have a vastly reduced warp presence akin to the Tau. This does not make them totally immune to chaos but are more resistant to its effects .
* Iota : Nulls on the Iota scale have very negligible warp presence and virtually non existent souls , and while they have a small area of effect are capable of actively disturbing low level daemonic manifestations and warp phenomena.
* Mu : The “true” nulls who do not possess any soul or reflection in the empyrean they cannot be affected by Daemons or psychic attacks. In fact there presscence harms powerful Daemons who are in many cases terrified by what they see as a gaping void. They have an area of effect measured in several miles around them .

### Blanks/Pariahs

As it turns out blanks are simply less potent pariahs (likely because the pariah gene might be inhibited or otherwise recessive ) . Unlike nulls , these untouchables have much more active influence on their abilities and the warp around them and are theorized to have some sort of anti-soul that drains warp energy from around them. They can also make use of abilities that are not so different from a psyker’s , perhaps by using the energy they absorb.

The pariah gene itself remains a mystery through the possibility of Necron gene tampering is the most accepted explanation for why it exists.

Classification:

* Theta : Low level pariahs who have a small area of effect but can manifest manifest abilities like energy manipulation on a small scale. Daemons will generally stay away from them and they are unaffected by warp based attacks. Most of the Thelal Guard is on this level.
* Zeta : The Mid-Tier Pariahs , who can banish Daemons to the warp with their mere presence and have extensive esoteric abilities that can be enhanced with certain implants . Axelis is of this class .
* Omega : These Pariahs are the bane of anything warp related and their abilities can affect even Greater Daemons and can drive cultists to insanity by removing the voice of their gods. They are incredibly rare with only three dozen currently known.
* Omega Minus : The counterpart to the Alpha plus psykers, there is virtually no limit to what an Omega minus can do. There are only two successful spicements on Atlantis and their birth single handedly drove every cultist in the city as well as causing the deaths of every unprotected psyker in it.
