"The Eversor is possibly the most gruesome of the many temples of the Officio Assassinorum. The Eversor specialise in shock and terror tactics, instilling fear of Imperial retribution into the hearts and minds of all who hold positions of power. Eversor Assassins are primarily used against rebel governors who have plans to move against the Imperium with a large armed force of renegades. Rather than meet this threat with a huge and costly war that will use up precious resources and probably leave whole planets ravaged, the High Lords will sanction the use of an Eversor Assassin. An Eversor rarely has just a single target. His mission will be to rip the heart out of the rebel operation, wreaking havoc and destruction. Such brutality ensures that the renegades are totally cleansed and that no would-be successors may take over. The enemy are utterly destroyed forever by the Eversor's unstoppable attack.

In order to fulfil these gruelling objectives, the Eversor temple trains its Assassins to be utterly ruthless and completely dedicated to the Imperium. Using specialised knowledge of genetics and human biology, every single Eversor Assassin is engineered to be a super-human killing machine, their bodies driven beyond normal human capabilities by genetic alterations and advanced bionics. In addition, the Eversor temple has developed a range of combat drugs to alter the Assassin's state of mind to that of a psycopath, and push his bio-enhanced body to its absolute limit."
