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)
