After returning home to Azeroth, Alleria Windrunner calls upon her estranged siblings - Sylvanas, the warchief of the Horde, and Vereesa, ranger-general of the Silver Covenant - to join her in a quest to retake their ancestral home, Windrunner Spire, from the undead who have overrun the place. On their journey, the three sisters will navigate both the dangers of the present and the ghosts of the past to discover if time and tragedy have divided them irrevocably - or if, despite everything, they are still a family.
