This hidden cave was used as a lair by a the Spider demon. She would remain here for a hundred years while feeding on her victim before hunting down new prey. It was here that she killed the wizard Rathmere and where she brought Piper Halliwell after trapping her inside a cocoon. The Spider demon was eventually vanquished at her lair when Phoebe and Paige arrived with several magical beings, including an Ogre, who vanquished her by stepping on her while in spider form.
