Priest are a fundamental piece of the Sabbat Pack. The spiritual leaders of the pack, the priest is (theoretically) second in command to the Ductus (though this is not always true). They officiates all the rituals and ceremonies observed by his fellows, and often creates a few for the sole use of the pack.
All packs have at least one Pack Priest, though some rare and large packs have two. They bear the responsibility for the spiritual wellbeing of their fellow Sabbat. In the event that the Ductus is eliminated, the Pack Priest becomes a temporary leader until a new leader can be appointed by the Bishop, Archbishop, or (in autonomous packs), the pack itself.
