Players last visited Northrend in Warcraft III: The Frozen Throne, when Arthas Menethil fused with the spirit of Nerhul to become the Lich King, one of the most powerful beings in the Warcraft universe. He now broods atop the Frozen Throne deep in Icecrown Citadel, clutching the rune blade Frostmourne and marshaling the undead armies of the Scourge. In Wrath of the Lich King, the forces of the Alliance and the Horde will venture into battle against the Scourge amid Northrend howling winds and fields of jagged ice.

With the opening of the Dark Portal, and the renewed war to stop the Burning Crusade抯 destruction of worlds, the heroes of Azeroth have given little thought to the frozen wastes of Northrend - and the terrible, ancient powers that wait there. Yet the brooding evils of the fallen Nerubian empire and their malevolent sovereign have not forgotten Azeroth?

The former death knight and now Lich King Arthas has set in motion events that could lead to the extinction of all life in Azeroth, as his undead armies and the necromantic power of the plague threaten to sweep across the land. Only the mightiest heroes can survive the frozen northlands with any hope of disrupting the plans of Arthas - and perhaps even challenge the Lich King himself and end his reign of terror for all time.
