Demonsbane

Demonsbane (2000, ISBN 0743418999) is an e-novella written by Robert B. Marks. It appears in print in the Diablo Archive (2008, ISBN 9781416576990).

In the book, Siggard, the only survivor of the battle of Blackmarch, unable to remember the battle's final hours—is driven to avenge those slain by the army of darkness. As he hunts the demonic army, Siggard pieces together the truth of that terrible battle...and finds his nightmare is just beginning.

Demonsbane was a book published in the spirit of the "e-book revolution." However, the market for e-books was quite small at the time and despite months of advertising on battle.net, sales were in the hundreds rather than the projected thousands.^[1]

Before being written, it was decided that Demonsbane should set the tone for the series, and help establish Sanctuary not only as a living and breathing game world, but also as a living and breathing world in literature. As such, Marks did a lot of world building using flavour quotes at the beginning of each chapter.^[1]

Legacy of Blood

Legacy of Blood (2001, ISBN 067104155X, reissue 2017, ISBN 9781945683015), the first novel based on Diablo by Blizzard Entertainment. The book was written by Richard A. Knaak. Legacy of Blood is intended for mature readers. It uses the same image as the cover of the Diablo II game box. It was collected in the Diablo Archive in 2008.

The book is written about a group of three men who stumble upon enchanted armor of unfathomable, immense powers that they have no clue about. The armor ends up belonging to a past warlord named Bartuc, who was the most brutal of all men to walk the earth, painting his armor each morning with the blood from the battle from his deceased foes. He was a Sorcerer who could control demons and used them to his own power to take over cities and countries in order to fiercely reign over the entire earth. He was eventually killed during an enormous battle by multiple people including his own brother Horazon. The armor was hidden away in a dark dungeon protected with dark magical powers where it sat dormant secretly calling to the main character, Norrec. Norrec was among the three tomb raiders when the armor was discovered. The three men were caught in a dire situation causing Norrec to put on the armor and reawaken the power of legions of demons and hell itself. His life would be forever changed...and one would question whether for the better or not.
