when I first went to the Anor londo I killed by mistake the woman who stand near the first bonfire after that the bonfire has not been able to activate , so is that because killing her or it's regular like the bonfire at firelink shrine ? and if It's because killing her can I do anything to return her ? me sorry for bad English
No bonfire "regularly" goes out. If you killed the Fire Keeper of Anor Londo, she's dead and the flame is out until you beat the game. If the Fire Keeper of Firelink Shrine is dead, that's because you released Knight Lautrec (guy in gold armor using Shotel) from the prison cell within the Cathedral in the Undead Burg and he murdered the Fire Keeper.
