Ritual site

 is a location in Point Lookout.

The Ritual Site is a large, subterranean complex used for worship by the Swampfolk. The entry to the cavern will be blocked by woodplanks until you obtain the quest The Dark Heart of Blackhall. At the very bottom is The Krivbeknih, and a unique knife, the Ritual Knife. Be warned. Taking the Krivbeknih or the Ritual Knife will cause several angry Swampfolk to spawn behind you. While exploring, the player can hear the same eerie whispers heard in the Virulent Underchambers in the Dunwich Building.
