Across Azeroth, a series of mystical visions called the "Radiant Song" struck prominent figures including Anduin, Thrall, and Alleria Windrunner, as revealed in the War Within announcement cinematic. These visions were linked to the World Soul of Azeroth itself. Locus-Walker, the Ethereal mentor of Alleria Windrunner, connected the Radiant Song to a pattern his homeworld K'aresh experienced before Void Lord Dimensius consumed it.
Locus-Walker delivered the revelation in a key exchange with Alleria:
"The visions you spoke of are the very same my people had... Before our world was consumed by the Void Lord Dimensius."
Alleria responded: "What!? You don't think... Could Xal'atath be seeking that same fate for Azeroth?"
He insisted she must confront her Void-touched nature rather than fear it — the only path capable of stopping history from repeating on Azeroth.
Dimensius the All-Devouring destroyed K'aresh, the Ethereal homeworld. The Ethereals built magical barriers to resist him, but the collision of arcane and dark energies stripped them of physical form, leaving them as the energy-bound Ethereals players know from Outland. Void Lords rarely manifest physically due to the energy cost, but when they do, the damage is planetary. Players encountered a weakened echo of Dimensius during The Burning Crusade — a preview of what his full presence could accomplish.
Xal'atath, wielder of the Dark Heart artifact, stated her ambition plainly:
"I long for the day our masters can truly pass into this realm."
That statement directly mirrored Dimensius's conquest of K'aresh. Locus-Walker's warning reframed the Radiant Song as the Void's advance signal — the same portent K'aresh received before its end. Players who followed Xal'atath's schemes to their conclusion could explore Liberation of Undermine, the War Within Season 2 raid where her plans reached their devastating peak. Alleria, uniquely able to exist between Light and Void, was the force capable of interrupting that cycle before Azeroth shared K'aresh's fate.
Locus-Walker is an Ethereal first introduced in the Legion expansion and Alleria Windrunner's mentor in Void magic. He survived K'aresh's destruction by Void Lord Dimensius, giving him direct knowledge of how the Void's advance omens work and why Alleria needed to embrace her Void-touched nature.
The Radiant Song was a series of mystical visions that struck major Azerothian figures including Anduin, Thrall, and Alleria Windrunner. Locus-Walker identified it as the same doom-omen K'aresh experienced before Void Lord Dimensius consumed that world.
K'aresh was the Ethereal homeworld, destroyed by Void Lord Dimensius the All-Devouring. When the Ethereals raised magical barriers to resist him, the collision of arcane and dark energies obliterated the planet and transformed its inhabitants into the energy-bound Ethereal beings players encounter in Outland.
Xal'atath is the Harbinger of the Void and a major cosmic antagonist in The War Within. She wielded the Black Blade of the Empire artifact, later manifested in a physical form, and pursued a plan to feed Azeroth's World Soul to the Void Lords — the same pattern of consumption that destroyed K'aresh.
According to Locus-Walker, yes. Alleria's unique ability to exist simultaneously in Light and Void made her the best candidate to confront Xal'atath. Locus-Walker specifically told her to harness rather than suppress her Void-touched nature to break the cycle the Radiant Song heralded.
The Void Lords sought to corrupt the World Soul sleeping within Azeroth, transforming it into a Dark Titan under their control. Xal'atath's schemes in The War Within were a step toward that goal, following the same pattern that destroyed K'aresh thousands of years before the events of the game.
