I have opened a new forum for the Diablo community.  Here you may discuss and share ideas about Diablo 3’s possible storyline and features.  A Diablo lore sub-forum was opened too.  Register and start discussions.

If you haven’t yet, I recommend reading Diablo: The Sin War Trilogy novel by Richard A. Knaak.  The novel reveals the origin of Sanctuary and how the patch 1.10 character Lilith was involved as a catalyst of the Sin War 3,000 years ago.

Lilith is revealed to be the daughter of Mephisto.

Did that itch your curiosity?  Could the novel shred bits of a possible Diablo 3 storyline?  Discuss it in the forum and read our interview with Richard A. Knaak held in October 2006 discussing the possible ramifications of his novel into the Diablo 3 storyline.
