Richard A. Knaak has revealed Pocket Books is releasing the Diablo: The Sin War Trilogy Archive on December 1, 2009. You should definitely get this one as an important lore source for events that happened three thousand years before the Darkening of Tristram, and the origin of the Necromancers. This book contains the shocking truth behind the creation of Sanctuary and the ancestry of men.
Knaak will be at BlizzCon 2009 through August 21-23, back and forth between the Tokyopop or the Pocket Books booths. Make sure to bring your Diablo novels to his signing schedule, or order them at the BlizzCon’s Blizzard Store.
