Hierophant Marius is the high priest of the Black Knights' Fortress, and is found on the first floor of the fortress, in front of an audience of black knights and monks of Zamorak. He administers the "Mark of Zamorak" on the player's face. Should the player remove their helmet in order to receive the mark, their suspicion level will rise to 100%. Marius is also one of the only NPCs in the game to carry a Zamorak staff.
- If the player attempts to read The Tome of Chaos in The Black Knights' Fortress, Marius will say "Keep your hands off my personal belongings, Dulcin!", or "Halt! The words of Zamorak are not for your eyes." if the player doesn't have the Black Knight captain's armour on.
