Before you can begin any new expansion in World of Warcraft, there are a few pre-requisite quests that will need to be completed, and The War Within remains the same. Players will journey to Khaz Algar, a subterranean continent west of Pandaria, to stop Xal’ atath from attacking Azeroth. The Harbinger of the Void is located in the deepest depths and mutating nerubian forces. Adventurers must make their way through four never-before-seen zones in The War Within.
