World of Warcraft: The Burning Crusade takes up where World of Warcraft left off, with the races of the Horde and the Alliance continuing to rebuild their lives among the shattered lands of Azeroth. Amid the fragile peace that exists between the factions come rumors that the Burning Legion’s age-old war against Azeroth – the so-called Burning Crusade – has been rekindled and threatens to consume the world in another firestorm of war and strife. Old allegiances fall and new ones rise as both the Horde and Alliance look to new friends in this time of need.
