My main problem with this episode is that they spent so much time on her death and on the fight to defeat Druaga that all of the critical questions of the series still have yet to be answered. In fact, Pazuz’s death already eliminates one avenue of answers - I’m still not quite sure what he was after or what was in those caskets, and now it looks like we may never find out.

I didn't think about it too much, because I mostly was thinking about making a post on Ahmey and her legacy. Personally I suspect that the creators rely on the connection with the game too much, or, as the silly wiki says, "It's All There in the Manual".
