World of Warcraft: The War Within isn't just another chapter in the 20-year history of the venerable MMORPG.
This is Blizzard's first attempt at a multi-expansion arc of stories, a trilogy called The Worldsoul Saga. In the War Within, the first expansion of the trilogy, we collect some of Azeroth's biggest names and delve underground to fight against the evil Void creature Xal'atath, best known for being smoking hot and wielding an evil smirk (and unbridled power stolen from about everyone).
