The Master of Sanctity, also sometimes styled High Chaplain or First Chaplain, is the head of the Chaplaincy in a Chapter of the Adeptus Astartes and head of the Chapter cult, its conglomeration of beliefs and cultural practices.
Different Chapters sometimes use different titles more in line with their own culture for this crucial position.
Immediately beneath the Master of Sanctity among a Chapter's Chaplains is the Reclusiarch, the head of the Reclusiam. In some Chapters the responsibilities of the Master of Sanctity and the Reclusiarch are merged into the same office.
