In Blizzard Entertainment's "Diablo(R)" and
"Diablo II," the recurring character of Deckard Cain
delivered quests, accompanied the brave adventurer, and, as the
last of the Horadrim, provided a link to the greater history of the
world of Sanctuary. Ever mysterious during these appearances, Cain
hinted at a larger story, providing snippets of it in his notebook.
"Diablo III: Book of Cain" is Cain's formal record of
this greater tale--a dissertation on the lore of the Diablo
universe, told by one who has witnessed and participated in some of
the epic events that make up the eternal conflict between the High
Heavens and the Burning Hells. Designed as an "in-world"
artifact from the Diablo universe, "Diablo III: Book of
Cain" includes Cain's revealing meditations, as well as
dozens of sketches and color artworks depicting the angelic and
demonic beings who wage constant war with one another.
