As in Warcraft III: Reign of Chaos, the single-player campaign of the Frozen Throne follows each of the main races in sequence. In this game, that is Night Elves (Maiev Shadowsong tracks the escaped Illidan Stormrage), Human (or Blood Elves, following the struggles of the last High Elves in Lordaeron after it was destroyed by the Scourge and the Burning Legion), and Undead (following Arthas' return from Kalimdor to Lordaeron, and his subsequent journey to find the Lich King of the Scourge). Unlike Reign of Chaos, there is no Orc campaign. However, there is a Diablo-style RPG campaign separate from the others that chronicles the early days of the Orc Horde's establishment in Kalimdor.
