The path to Undermine(d) stretched across several major Dragonflight and early War Within patches, each one pulling the curtain back further on the threat Xal'atath had been quietly building. Here is how that story unfolded.
The Primal Incarnates and the Dark Heart
The closing chapters of Dragonflight introduced the Primal Incarnates, ancient proto-dragons who rejected the Titans' order and sought to restore primal chaos to Azeroth. Of the four, Iridikron the Stonescaled proved the most calculated and dangerous. While Raszageth fell and Fyrakk was ultimately defeated at Amirdrassil, Iridikron operated at a remove, pursuing a separate objective.
That objective led him to the Forbidden Reach, where he recovered the Dark Heart — an ancient relic that predated the Dragon Soul. Neltharion, who would not become the corrupted Deathwing until later, had crafted it as an early prototype: a vessel designed to concentrate and channel immense draconic power. The artifact had lain forgotten in the Forbidden Reach for millennia, its origins buried beneath layers of history most of Azeroth had stopped looking for.
Dawn of the Infinite and the Extraction of Primal Energy
With the Dark Heart in hand, Iridikron moved on his true prize: the remains of Galakrond, the proto-dragon whose sheer magnitude had shaped the earliest history of dragonkind. The Dawn of the Infinite mega-dungeon placed adventurers directly inside the fractured timeways that formed around this act.
What Iridikron Actually Extracted
Iridikron used the Dark Heart to siphon primal energy from Galakrond's remains. Galakrond was a primal proto-dragon, immense, chaotic, and wholly unaligned with the Void. The energy extracted was raw primal essence, not Void-affiliated in any way. The distinction mattered: this power fed into a plan aimed at destabilizing the Dragon Aspects and, ultimately, reshaping Azeroth's fundamental order.
The extraction fractured the timeways around the site. Chromie and a group of adventurers intervened, fighting through collapsed timelines and temporal anomalies in an attempt to stop the ritual. Despite their efforts, Iridikron completed his objective and escaped. The Dark Heart's power had been tapped, and the ripples spread outward through time and space almost immediately.
The Harbinger and the Radiant Song
As Dragonflight wound toward its close, reports of unsettling visions spread across Azeroth. These were called the Radiant Song: eerie, resonant impressions that seemed to carry no single source. They appeared to adventurers, mages, and seers alike, and carried a weight that felt less like prophecy and more like a signal.
Alleria Windrunner took the threat seriously from the beginning. She led investigations that brought her and allied adventurers to Telogrus Rift, the shattered dimensional space that served as home base for the void elves she had helped forge — and eventually to Ulduar, the ancient Titan stronghold in the Storm Peaks. Hostile forces moved against the Titan facility, a sign that whatever was behind the Radiant Song considered the Titan network a threat worth neutralizing.
Locus-Walker's Warning
Alleria's Void mentor, Locus-Walker — whose homeworld of K'aresh had been consumed by the entity Dimensius — recognized the character of these visions. He noted that they bore the signature of events he had witnessed before: the kind of omens that preceded existential calamity rather than ordinary conflict. His warning carried weight precisely because it came from personal experience, not theory.
Also operating across Azeroth during this period was a figure referred to only as the Harbinger — a shadowed entity whose influence appeared in disconnected incidents and whose alliance with Iridikron had been confirmed, if not explained.
Xal'atath Unmasked
Patch 10.2.7 brought the revelation: the Harbinger was Xal'atath.
Her history was long and violent. During the Black Empire era — an ancient period long before the Burning Legion ever set foot on Azeroth — Xal'atath had been imprisoned within the Blade of the Black Empire. The blade itself surfaced in the modern era as a shadow priest artifact weapon during the Legion expansion, giving players their first encounter with the entity's whispers. She freed herself from that imprisonment during Battle for Azeroth and had been moving in darkness ever since.
By the time her identity was confirmed, Xal'atath had already positioned herself at the center of every major destabilizing event across the Dragonflight endgame. Iridikron's extraction of primal energy, the Radiant Song visions, the attacks on Ulduar; each piece had served a larger design.
New Alliances and the Road to Undermine(d)
Faced with a threat that touched the Titans, the Dragon Aspects, and the Void simultaneously, Azeroth's leaders consolidated. Jaina Proudmoore brought Alliance naval and arcane resources into alignment with the Horde's response. Magni Bronzebeard, speaking for Azeroth itself through his communion with the world-soul, provided critical intelligence about what the planet sensed beneath its surface. Others across both factions moved to close gaps Xal'atath had exploited.
The trail led to Undermine, the vast labyrinthine city built beneath Kezan by goblin engineers and ruled by Chrome King Gallywix, who had become entangled with forces larger than even his considerable ego could manage.
Patch 11.1 "Undermine(d)" — February 25, 2025
Patch 11.1 launched on February 25, 2025, delivering the story's next confrontation through the Liberation of Undermine raid. The raid brought adventurers through the mechanical depths of Kezan's underground city, dismantling Gallywix's operations wing by wing before reaching Chrome King Gallywix himself as the final boss.
The patch also expanded the goblin homeland zones and continued the Worldsoul storyline established at the start of The War Within. Xal'atath's broader ambitions — the full shape of what she had been building since the Black Empire era — moved closer to the surface.
By the time Patch 12.0.5 — Lingering Shadows arrived in 2026, the story beats seeded in Dragonflight's closing acts had fully resolved into The War Within's complete first arc. Looking back, the Iridikron thread and the Radiant Song were the earliest visible signs of what Xal'atath had set in motion.
FAQ
What is the Dark Heart item in WoW?
The Dark Heart was an artifact recovered by Iridikron in the Forbidden Reach. Neltharion crafted it before his corruption (before he became Deathwing) as an early prototype for what would eventually become the Dragon Soul. It functioned as a vessel capable of concentrating and channeling vast amounts of draconic power.
What energy did Iridikron extract from Galakrond's remains?
Iridikron extracted primal energy from Galakrond's remains using the Dark Heart. Galakrond was a primal proto-dragon with no Void affiliation; the energy involved was raw primal essence tied to the chaotic forces that predated Titan order on Azeroth.
Who is Xal'atath and when was she imprisoned?
Xal'atath is an ancient entity of significant power who was imprisoned within the Blade of the Black Empire during the Black Empire era — long before the Burning Legion's campaigns against Azeroth. Players first encountered her through the blade as a shadow priest artifact weapon in Legion. She escaped her imprisonment during Battle for Azeroth and operated covertly until being revealed as the Harbinger in Patch 10.2.7.
What role did Alleria Windrunner play in the War Within lead-up?
Alleria led the primary investigation into the Radiant Song visions. She brought adventurers to Telogrus Rift and Ulduar, working to identify the source and nature of the disturbances. Her background with the Void, combined with Locus-Walker's counsel, positioned her as a key figure in recognizing Xal'atath's signature before the full reveal.
Who is Chrome King Gallywix and why is he the final boss of Liberation of Undermine?
Chrome King Gallywix is the former Trade Prince of the Bilgewater Cartel who rebuilt his power base beneath Kezan in Undermine. By Patch 11.1, his entanglement with the forces surrounding Xal'atath made him a direct obstacle to the heroes' broader mission. He served as the final boss of the Liberation of Undermine raid, which launched with Patch 11.1 on February 25, 2025.
What happened to Iridikron after Dawn of the Infinite?
After completing the extraction of primal energy from Galakrond's remains and escaping the intervention at Dawn of the Infinite, Iridikron continued working in concert with Xal'atath. The nature and full extent of their alliance were expanded in subsequent patches. He did not appear as a raid boss in Patch 11.1; his story continued through the broader War Within arc.
Where does Patch 11.1 fit in The War Within expansion?
Patch 11.1 "Undermine(d)" was the first major content patch of The War Within expansion, released February 25, 2025. It followed the expansion's launch content (the Isle of Dorn, Hallowfall, and Azj-Kahet) and pushed the Worldsoul storyline forward through the Liberation of Undermine raid and the expanded goblin homeland zones.
Is the Radiant Song related to the Void or to primal forces?
The Radiant Song's origins were tied to Xal'atath's machinations rather than to primal energy specifically. Xal'atath operated through Void-adjacent influence, and the visions appeared designed to test, distract, and probe Azeroth's defenders. Locus-Walker's recognition of the omens as familiar calamity signs pointed directly to her involvement, which was confirmed when she was unmasked as the Harbinger.
