Following the Age of Apostasy, led by Goge Vandire, came the Wars of Vindication within the Office of Assassins itself. The Officio had become riddled with corruption and the Grand Master of Assassins brought it to its knees in order to purge it. The Officio was reduced to ruins and needed a full reorganisation. Following a thorough investigation, Inquisitor Jaeger deemed that a special order of the Inquisition was needed to monitor and to control the Officio much more closely. His proposal was accepted and the Ordo Sicarius was created, to monitor the Office for signs of corruption and to expose and to punish the responsible parties.
