So I made it to Anor Londo, and I went down the stairs to where Siegmeyer complains about the three knights in the room. As I was trying to dodge an attack, a knight hit him and he turned hostile towards me. I know I can visit that dude at the Undead Parish to repent "my" sins, but is there a way to leave Anor Londo once you jump off that ledge to get inside the huge cathedral/palace? If so, can I do it before I fight Smough and Ornstein?
Really wishing Dark Souls had save files right about now, lol.
