Witnessing a falling star, the Nephalem travelled to Tristram where they confronted and defeated an awakened evil. Together with new allies, the Nephalem then moved towards Caldeum, reviving (and defeating) Zoltun Kulle, retrieving his Black Soulstone, and vanquishing Belial. At Bastion's Keep, the Nephalem fought the Army of Sin, but after trapping Azmodan, the last of the Evils, in the Soulstone, were betrayed by Adria. Thus, Diablo walked the earth again.
