Diablo III is set twenty years after the destruction of the Worldstone. The world of Sanctuary was prepared for an invasion from the Burning Hells in the immediate aftermath, but the invasion never happened. This prompts Deckard Cain to seek information as to why. Much of the story will be also based around what became of Tyrael, the Archangel of Justice, after the events of Lord of Destruction
Diablo III will end the storyline that began in the original game. It has been confirmed, though, that it will not be the last game of the franchise and new storylines will develop. Chris Metzen, vice president of Blizzard's Lore department, knows where the story will go after the game.
Long before the creation of Sanctuary, the Eternal Conflict between angels and demons raged on for untold millennia. Blizzard Entertainment teamed up with renowned director Peter Chung and acclaimed animation studio Titmouse to create this unique vision of a fundamental moment in the battle between the High Heavens and the Burning Hells.

Set to be released May 15, Diablo III: The Order is the next novel in the Diablo universe, which focuses on Deckard Cain's quest to find what seems to be other Horadrim, set years before the events of Diablo 3. There's a preview of the first seven chapters available freely.
Book of Cain
The Book of Cain is a book detailing the history, cosmology and lore of the Diablo universe, written through the eyes of Deckard Cain. The book is intended to explain and elaborate on the lore behind the games, which according to Chris Metzen had over the years been worked on by so many different writers and teams that it was a mess.
It expands the lore with a creation myth, information about the origins of the High Heavens and Burning Hells, a detailed account of the Sin War and profiles on the major characters of the universe including the Angiris Council and Great Evils. It also explains the history of Sanctuary in greater detail.
