Following in the tradition of previous Blizzard expansion sets, Warcraft III: The Frozen Throne provides gamers with a vast new chapter in the epic Warcraft saga. In the single-player campaign, players revisit the war-torn world of Azeroth. Several months have passed since Archimonde and the Burning Legion were defeated at the battle of Mount Hyjal, yet a new threat has arisen throughout the land.

The evil Lich King Ner'zhul has been imprisoned inside the Icecrown glacier, deep within the arctic continent of Northrend. Although the former Orc Shaman lacks physical form, his soul lives on, forever seeking a means to escape his icy prison. As the saga continues, it is revealed that both the Night Elf renegade, Illidan, and the traitorous Death Knight, Arthas, seek the Icecrown glacier and the mysterious powers found inside. To save all of Azeroth from the forces of darkness, players must traverse uncharted lands and battle treacherous new enemies while uncovering the schemes of these nefarious beings.
