Priest are a fundamental piece of the Sabbat pack. The spiritual leaders of the pack, the priest is second in command to the Ductus (though this is not always true). They officiate all the rituals and ceremonies observed by the group, and often create a few for the sole use of the pack.
All packs have at least one Priest; rarely, some 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 Priest becomes a temporary leader until a new leader can be appointed by the Bishop, Archbishop, or in autonomous packs, the pack itself.
