3: This last is a bit of speculation, but quite interesting I think. The Balance the necromancers are guarding is the balance in Sanctuary. They don't want demons or angels there, but what they do outside of Sanctuary they care little about, so long as it doesn't affect humanity.
Perhaps though there is some other aspect of the balance with is more "global" and connected to all the realms (including those of the unknown beings who stop Trag'Oul from entering Sanctuary in the Sin War). Perhaps humans could fulfill some role there which has not yet been revealed.
This could certainly be possible and I would absolutely welcome it. I'm fond of stories that unexpectedly expand in scope.
Quote fromBecause the average reader isn't all that interested in getting the whole dualistic message slapped in their face all the time. The books are not primarily meant as tomes of knowledge for lore-fanatics like ourselves but for Diablofans who wish to get a little deeper into the Diablo Universe while at the same time enjoying the story. Mentioning Heaven as an enemy makes no sense when Zayl is pursuing demons.
Hah, wouldn't be the first time that I got carried away about something. Thinking back again to the last scene of The Sin War, the pact between Imperius and Mephisto that was made was obviously broken at some point between its creation and Diablo 1, but yet we still see Heaven react in such a mild manner? Wouldn't it be expected that the moment the Prime Evils broke the pact that Heaven would come streaming in full force?
