Trivia

 * The original text was present in World of Warcraft vanilla, depicting the eredar as being partly responsible for the corruption of Sargeras. The Burning Crusade introduced the draenei and expanded upon the background of their race, retconing the content of that book, which was eventually later edited to match the new lore.
