In the Lost Bastille I was running around with a torch and I've found a shadowy figure in the room next to Boss Soul Weapon guy that is only revealed when I have a torch, and it only shows his shadow. He is sitting cross legged on a little mat in the corner of his cell. You need the Antiquated key to open his room. I don't remember seeing him on the 360. Is it a DLC thing or does anyone even know?
