The History of Warcraft (also known as the “history of the Warcraft universe“) is a comprehensive account of lore created by Blizzard as background information to the World of Warcraft universe, and was made up of the entirety of Blizzard’s published record so far. The full text was available on the official World of Warcraft site, but was removed for some unknown reason. In the absence of lore on the official sites, most (perhaps all?) of this material can be read within the World of Warcraft itself as in-game books.
