Liber Exorcismus
The Liber Exorcismus is a hallowed text, owned by the Exorcists Chapter.[1]
It is traditional for members of the Enochian Guard to adorn themselves with excerpts from the Liber Exorcismus, and other such texts, before a battle. They believe that the verses will imbue them with righteous strength, when the Emperor's light is furthest from their reach.[1]
