The Officio Assassinorum is a highly secretive agency of the Imperium of Man's government that employs different "temples" that train human Assassins to further the goals and protect the security of the Imperium of Man. Although the Inquisition strikes fear in the hearts of all Imperial citizens, loyal and corrupt alike, the deadly disciples of the Officio Assassinorum strike fear in the hearts of even the most savvy, battle-hardened of Imperial warriors.
