The Highpriest leads the Cult who worships in the site found within a temple in the forest in the Lake of Sorrow, found outside of Moonville. He is in possession of a key.
| Spoiler: When the Princess meets the Highpriest, she is either witness to or participates in a ceremony that summons four Karmanthi and eventually Numinous Belphegor. |
| Note: The Highpriest should not be confused with the Highpriest who had been buried in a sarcophagus in the tomb on the Isle of Prisoners, who's only remains is a key. |
