My entry for the WoW Legion contest. This is the Central Archive of the Nathrezim(Dreadlords).
In the book Illidan, Illidan and his Demon Hunters portal hop taking the fight to the legion. One of these places was the Dreadlord home world where Illidan specifically goes to their Library holding all the Legions history and information.
Please read through the annotations for more story and context.
