The Culexus Assassins are the most sinister of all the assassins. They are null-entities in the warp, creating a terrifying aura of unnaturalness and paranormal fear around themselves by merely existing. Psykers [[Psyker]]s within range of a Culexus Assassin are so unnerved by the experience they may simply break and and attempt to flee, making these Assassins perfect witch-slayers.

It is possible that Culexus Assassins possess the "[[Pariahs|Pariah ]] Gene" (making them soulless, accounting for their having no warp-presence), thus also making them perfect candidates for becoming Necron [[Pariah]]s. Though if this is truly the case, it becomes interesting to consider how these Pariahs are recruited into the Officio Assassinorum, as carriers of the Pariah gene are incredibly rare, an entire planet may only produce a single candidate in a whole generation. This rarity, coupled with the extremely high rate of student attrition within the organisation may give an indication of how many Culexus Assassins may be in existence at any one time.
