The Forge of SoulsIntroduced in Wrath of the Lich King
For many years, champions among the races of Azeroth have stood against the Lich King only to be slaughtered mercilessly and forced to serve in his army of undead horrors. In his ongoing struggle to stop the Lich King, Tirion Fordring of the Argent Crusade has joined forces with Darion Mograine of the Knights of the Ebon Blade in order to assault Icecrown Citadel with a unified army called the Ashen Verdict.
With the Lich King's attention focused on the Ashen Verdict's attacks, covert agents have managed the near-impossible feat of infiltrating the citadel and providing invaluable intelligence on the frozen halls and their wings: the Forge of Souls, the Pit of Saron, and the Halls of Reflection. If the champions of justice are to have any hope of defeating the lord of the dead, they will have to rely on courage, fortitude, and an increasingly narrow window of opportunity to strike at Icecrown Citadel from within its own walls.
