Shortly after the pre-expansion launch, you’ll be called upon to defend Azeroth from an undead invasion as the Scourge sweep across the land. Players will embark on a quest to establish a foothold in Icecrown, where the barrier between Azeroth and the afterlife has been shattered, and prepare for the coming journey into the Shadowlands. This limited time pre-expansion event will only be available until the launch of Shadowlands, so make sure to log in to experience it and earn special rewards.
