The Assignment

The Imperium measures and records the psionic activity and power level of psychic individuals through a rating system called The Assignment. Comprised of a twenty-four point scale, The Assignment simplifies the comparison of psykers to aid Imperial authorities in recognizing possible threats.

Beings which utilize psychic powers, or psykers, exist within many of the races residing within the galaxy. Human psykers, all Eldar, Ork Weirdboyz, Space Marine Librarians and Chaos Sorcerers all fall into this catagory. Beings such as Daemons of the Warp are made of purely psychic energies. Due to their use in the armies of Man and their relative abundance in the Imperium’s enemies, the Imperium has devised a way to clasify all psykers it may come across.

The average Homo Sapiens Imperial is judged to have an Assignment rating of Rho or Pi. These individuals cannot consciously or subconsciously draw power from the Immaterium and are not able to become possessed without outside psychic influence. As the vast majority of Mankind falls into this Assignment level, the common Imperial citizen poses little psychic security threat.

Nevertheless, uncommon individuals are birthed every day with Assignment ratings exceeding Pi. By Imperial Edict, these men and women are to be discovered and brought to the attention of the Inquisition to protect against harmful psychic events. With the multitude of threats besieging the Imperium, however, it is only truly practical to investigate those suspected of Iota level talent or greater.

Psychic screening is mandatory for an Imperial citizens when applying a Cognomen, usually at the age of 10.

The Imperial Assignment: Psionic Levels

In ascending order:

Rho // Pi
No manifestation of psychic talent (common human being).

Omicron // Xi // Nu // Mu // Lambda // Kappa
Unconscious and minor level of psionic brain activity. Such low levels of talent only manifest in high-stress experiences and remain beyond the control of the individual. Phenomena are commonly explained as “good luck” or “fluke” occurrences.

Iota // Theta // Eta
Conscious and moderate level of psionic talent. As the individual is able to control abilities with effort, subjects of Iota level and higher are true psykers and under the jurisdiction of the Inquisition and Adeptus Astra Telepathica.

Zeta // Epsilon
Very high level of mental psychic activity. Manifesting early, these levels of talent (and those above) require the immediate attention of Imperial authorities and represent a true security threat.

Delta // Gamma
Occurring in approximately one-per-billion human births, Delta and Gamma level psykers exhibit extreme levels of psionic ability. Unless discovered quickly, death or possession are common results of the untrained mind being unable to handle this level of mental energy.

Beta // Alpha
Exceedingly rare and dangerous. Mainstream Medicae Imperialis discussion agrees that current human beings do not possess the necessary evolutionary development to contain Beta and Alpha levels of psionic talent. As such, the great majority of those discovered at this Assignment rating usually suffer from mental instability.

In the rarest of all cases, the twenty-four point scale of the Assignment does not adequately characterize a being of indescribable ability. Such individuals, for all intents and purposes, pass beyond the scale entirely. These subjects are known as Alpha-Plus psykers.
Uncontained, Alpha-Plus psykers represent an immediate and catastrophic threat to the Imperium.
In theory, there is nothing that a trained Alpha-Plus psyker cannot accomplish through force of will; from snapping a Titan in half to summoning a legion of Greater Daemons.
Representing such a great danger, the Inquisition usually executes Alpha-Plus psykers on sight unless the possibility for capture is nearly assured.
