Ulduar (pronounced /'əlduːɑr/)[2] is the biggest titan-forged complex on Azeroth. Situated in the Storm Peaks, it notably encompasses the Halls of Stone, the Halls of Lightning, and the prison of Yogg-Saron.

Official Blizzard description

For millennia, Ulduar has remained undisturbed by mortals, far away from their concerns and their struggles. Yet since its recent discovery, many have wondered what the structure's original purpose may have been. Some thought it a city, built to herald the glory of its makers; some thought it a vault containing innumerable treasures, perhaps even relics of the mighty Titans themselves. Such speculations were wrong. Beyond Ulduar's gates lies no city, no treasure vault, no final answer to the Titan's mysteries. All that awaits those who dare set foot in Ulduar is a horror even the Titans could not, would not destroy, an evil they merely... contained.

Beneath ancient Ulduar, the Old God of death lies, whispering.... Tread carefully, or its prison will become your tomb.[3]

Since discovering Ulduar in the Storm Peaks, adventurers had journeyed to the titan city to learn more about its mysterious past. Further exploration revealed that the magnificent complex included a prison, intended to permanently confine the Old God Yogg-Saron. This ancient horror had corrupted its guards, and was breaking through the last of its restraints.

Faced with the peril of Yogg-Saron's imminent freedom, a band of mortals made preparations for a sweeping assault on the city. Overcoming the legions of iron minions and towering defenses at the city's entrance took tremendous strength, but even that great victory may not be enough to overcome the madness that dwells below.[4]

Ulduar is located at the very northern end of the Storm Peaks, making it the most northern location in all of Azeroth. After various quests it is revealed that Loken attacked the city with his iron dwarves and took it from the resident earthen.

The Halls of Stone can be found on the western edge of the "island", the Ulduar raid to the northwest, and the Halls of Lightning to the northeast.

The small Alliance and Horde camps were replaced with a medium-sized camp named Copperpot Camp, run by human Chester Copperpot and guarded by Copperpot Goons — all level 80 elite humanoids of various races. A meeting stone is located just nearby.

To the southwest of the Halls of Stone lies the Temple of Wisdom.

Ulduar was thought to have been cleansed of the corruption that previously infested it, with the Earthen and Mechagnomes resuming command of the facility under the eyes of their Keepers. During the quest N [100] The Diamond King, it is implied that Ulduar was normally meant to have visitors, with Visitor Information Representatives available for inquiries and curators posted to report if an area was not enterable due to repairs or maintenance. Visitors were even asked to fill out a Visitor Satisfaction Survey before they left.

During the Legion's third invasion of Azeroth, a group of demons broke into the facility intending to unearth information that would lead them to the Pillars of Creation. To make matters worse, the whispers of the previously defeated Old God Yogg-Saron were heard once more throughout the halls, and groups of N'raqi returned to Ulduar for an unknown purpose.

An unknown entity time-traveled to Ulduar in order to tamper with and artificially age the titan locks holding Yogg-Saron in place, releasing the Old God forty millennia early. Vormu of the bronze dragonflight came too late to stop this modification of the timeline.[5]

In the RPG

The RPG Icon 16x36.png This section contains information from the Warcraft RPG which is considered non-canon.

Along with Uldum and Uldaman, there exists a third base of the titans called Ulduar. A fourth base, Maraudon, is the location of Terramok, an ancient titan vault. A fifth base is located under Bael Modan. Ulduar is located in The Storm Peaks of Northrend.

Ulduar is a mysterious subterranean realm of ice and stone. This was once the storm giants' stronghold, but they didn't build it. Brann Bronzebeard believes it to be a titan city (it is also a production facility and prison), as it matched the design of the two temples in Northrend and other ruins dwarves found elsewhere (and because it contained the word "Uld"). Massive buildings protrude from the tops and sides of mountains, many hundreds of times taller than a human. When Brann Bronzebeard first explored the area, a section he discovered was covered in rock and ice. He thought it was an amazing place but couldn't tell from outside, because it was completely hidden to him. The exterior he saw looked like the other peaks to him: a jumble of rock and ice cut at angles only nature would have produced. The entrance he discovered was well-hidden and heavily guarded by crystal golems.[1] However large sections of the facility are now visible aboveground.

Inside, Ulduar is a profusion of tunnels and stairs and balconies. The entire place appears to be carved out of a massive cave, and many of the levels are natural ledges. It has the feeling, as if nature were improved upon rather than replaced or recreated. The surfaces are a strange mix of smooth and unaltered stone and ice, as when a master sculptor works in stone and lets the material’s natural texture add depth and beauty. It shows where the dwarves got their skill in stonework, but judging by Ulduar they're still a long way from matching their creators.

When Brann was exploring the place, the storm giants themselves were so few in number that one could wander the halls without ever meeting one — he believed this was probably for the best, since no one was supposed to gain entrance. The giants are a dying race desperately avoiding their fate. They seem to think another race will vanquish them some day, and so they hide in Ulduar rather than girding for battle. They are too frightened to battle the Scourge, but apparently they hate it. Ulduar is likely a treasure trove of information on the Titans and their activities.[1] Since then the storm giants have moved to the Howling Fjord.


Ulduar preview


  • The name "Ulduar" is possibly a reference to the god Ulthar from H.P. Lovecraft's Cthulhu Mythos. Ulthar was an "Elder God" (much like World of Warcraft's Titans) sent to Earth to keep vigil over the "Great Old Ones" (which World of Warcraft's Old Gods are based upon), much like how Ulduar is a prison for an Old God. Ulduar as a structure is also similar to Kadath, another of Lovecraft's fictional locations. It is a massive castle built upon a mountain in the middle of the Cold Wastes, and the home of the Great Ones (the earthly gods).
