Pontifex Maximus was the highest rank achieveable in the Zarosian church during the Second Age. The Pontifex Maximus wears a sort of metal with two prongs on the side. This position was held by a human before Azzanadra.
^Azzanadra, RuneScape. "Do not mock my hat – it deserves respect! It is a sign of my devotion, my position in the church!"
^Jhallan's memory (book)RuneScape "Some years later, when the human occupant of the position died, Azzanadra was elevated to the rank of Pontifex Maximus"
