Ulduar Ulduar ( ) is a complex in the Storm Peaks , and encompasses two dungeons — the Halls of Stone and the Halls of Lightning — and a raid dungeon simply named Ulduar . Lore . Along with Uldum and Uldaman , there exists a third base of the titan s 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 giant s ' 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 golem s . 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 . Since then the storm giants have moved to the Howling Fjord . Official Blizzard intro . " 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 maker s ; some thought it a vault containing innumerable treasures , perhaps even relics of the mighty Titan s 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 . " In World of Warcraft . 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 Goon s — 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 . It is possible to uncover this map segment without the use of flying by swimming along the coastline very closely to the shore .
