Hey I have the Darkmoon Seance Ring (which I hear is also the Priest Ring that Wiki refers to). I went down to the second bonfire in Anor Londo (which I believe is the bonfire right after the two ridiculous archers?). I've been in that room before but I rolled around and destroyed most of the things in the room. I have the ring equipped but I see nothing different in the room, no hidden pathways or anything. I've tried attacking the walls and no luck, every source I checked out says the same thing. Not sure what to do or where to go to join this covenant.

This is one source I've been trying to follow: http://darksoulswiki.wikispaces.com/Covenants

Edit: Nevermind found it out myself, I guess I missed out on a bonfire.
