After six years of hiatus, trapped within the Nightmare, Archdruid Malfurion Stormrage is back to business in Azeroth. Your first sighting of him will be at the center of the tornado of Darkshore, and lastly in Mount Hyjal.

But … when and how did he return from the Emerald Nightmare? Many fans who don’t read the novels will have this self-question in their minds when they see Malfurion and don’t find any quest explaining his return.

All your questions are revealed in World of Warcraft: Stormrage — the three-time Locus Magazine Bestseller by New York Times Bestseller author Richard A. Knaak. It was released back on February 2010.
