Hierophant
From Tardis Wiki, the free Doctor Who reference
A hierophant was the person who brought the religious congregants into the presence of the holy, or whatever they felt was holy according to Bernice Summerfield. It was a term from Ancient Greece a contraction of taheiri ("the holy") and phani ("to show"). On Zordin they became active after the Great Leader was destroyed. (AUDIO: Private Enemy No. 1)
