World of Warcraft: The War Within, ett rollspelsäventyr från 2024, tar spelare till underjordiska Azeroth för att möta Hotbäraren från Tomheten. Kärnspelupplevelsen inkluderar utforskning av nya områden, introduktionen av "Delves" för solo- eller gruppäventyr med NPC-sällskap, samt det nya "Warbands"-systemet för kontobred progression. Karaktärerna kan anpassas ytterligare med nya "Hero Talent trees".
In The Ghosts of K’aresh, the campaign continues as more pieces to a troubling puzzle fall into place. Players immerse themselves in The War Within story as it leads up to the next chapter of the Worldsoul Saga—Midnight. There’s some unfinished business to be had on K’aresh and the specter of an old enemy looms large. Forces with ill-intent are determined to bring forth Dimensius, the All-Devouring once more to finish off the ethereals. Should he arise, Azeroth will also be in peril from this dangerous Void Lord.
