The Officio Assassinorum is a highly secretive organisation which trains terrifying bio-modified killers for assassination missions sanctioned by the High Lords of terra. The diverse Temples of the Officio specialise in the different arts of murder from the bittr kiss of poison to berserk slaughter. The Inquisition has close ties with the Officio Assassinorum and their operatives often have cause to work together.

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.

An Officio Assassinorum Operative may be added to your Daemonhunters or Witch Hunters army as an Elite choice as long as your army includes an Inquisitor.
