I am on Disc 2 around character level 50, and have got to the point where Mildheim (?) village [you know the one where you fall ill for ages and there is that cute nurse] has become a lifeforce pool and one of the female characters [don't know name] has just died. I just don't know what to do next. I have been all over the map, and only thing I can see to do is to go to Midgar, but cannot get the key from Bone Village [will keep trying].

Any suggestions on what to do next?
