Fall of the Lich King
Released in December 2009 World of Warcraft Patch 3.3
As the final battle against the Lich King approached, the human sorceress Jaina Proudmoore and the Banshee Queen Sylvanas Windrunner journeyed to the icy heart of Northrend. Both had come for different reasons: Jaina hoped to discover whether a part of her former friend and lover, Arthas Menethil, still lived; Sylvanas longed to take revenge on her old enemy. With the aid of these two heroes, Azeroth's champions stormed Icecrown Citadel and vanquished the Lich King's minions. Their confrontation with the Lich King involved thousands of souls consumed by Arthas's blade, Frostmourne. Ultimately, Arthas was slain, and the heroes who triumphed over him learned a chilling truth about the existence of the undead Scourge.
