Defenders of the Alliance and the Horde—a great and ancient enemy has set its sights on Azeroth once more, and soon the land will be consumed in a storm of fel fire. Starting on August 30, kingdoms will burn, heroes will fall, and the world will stand on the precipice of destruction with the launch of World of Warcraft: Legion!
All hellfire is about to break loose, so steel yourself for the return of the Burning Legion by pre-purchasing World of Warcraft: Legion digitally at www.wowlegion.com. Players who pre-purchase will receive an instant level-100 character boost, as well as unlock early access to the new Demon Hunter hero class prior to the expansion’s release.
