The Eversor Temple is possibly the most gruesome of the many temples that train Imperial Assassins for the Officio Assassinorum. The Eversor Assassins specialise in shock and terror tactics, instilling fear of Imperial retribution into the hearts and minds of all who hold positions of power in the Imperium of Man.
