The Scourge is one of two major undead factions existing in the world of Azeroth (the other being the Forsaken), and a major player for control of the world. They have a vast "empire". Created initially as the precursor to an invasion by the Burning Legion after their previous failures, the Scourge broke free from their demonic masters and — under the iron rule of the dread Lich King — have built up their power base on the Arctic continent of Northrend. Their influence spreads throughout Northrend, as well as the Plaguelands in northern Lordaeron and southern Quel'Thalas, and even Kalimdor to a small degree. A terrifying and insidious enemy, the Scourge remains perhaps the most dangerous threat to the world of Azeroth.
