Beyond the daddy dragon was a tomb with a single snakeman who was easily killed. I learned the "path of the dragon" gesture on a corpse just passed him and had a pretty good idea where to try it too (since the corpses there were also in the same pose). The crypt gives way to a dark version of the starting graveyard zone. Only this one has no fire and is guarded by grave wardens and the invader Daughter of Crystal Kreimhild (I assume that's the Crystal Sage from before). She isn't too challenging as I just kick her off a cliff.
The spear statue boss in this dark world is much stronger too, but fortunately I have both Bill the swordmaster and Agnon Rhyat (sunbro player) to assist - finally a coop player can enter the boss fog! Agnon falls in battle, but it is enough for me to learn the boss' moves and earn a victory. Thanks Agnon! In the dark version of Firelink shrine I also find eyes of a Firekeeper, and the sole inhabitant - the creepy hag lady - is here telling me to leave before the darkness takes me. Good suggestion.
I warp back to the regular Firelink Shrine and give the eyes to my regular Firekeeper. She says that it's forbidden but plugs them in anyway, then asks if I wish for a world without fire. Having seen exactly what "a world without fire" is I say no. This upsets her, and she asks that I slay her so that I can take the eyes away from her. Again I have to refuse her request and leave her to get used to seeing the world as it is.
That's got to be a safety issue...
PS. My graphics card finally surrendered and lowered the visuals so I could play without crashing. The quality of the screenies will suffer a bit as a result! :P
