Lore
With Uldum and Uldaman, there is a third base of the Titans named Ulduar. A fourth location, Maraudon, is the location of Terramok, an ancient titan vault. A fifth location, a storage facility, is located under Bael Modan. Ulduar is located at The Storm Peaks of Northrend. It is controlled by storm giants, and their minions the crystal golems.

Ulduar is a mysterious subterranean realm of ice and stone. This is the storm giants’ stronghold, but they didn’t build it. It is a Titan city — it matches the design of the two temples in Northrend, and other ruins dwarves have found elsewhere (And like Uldum and Uldaman, its name starts with “Uld”). It’s an amazing place but one would never know it from the outside, because it’s completely hidden. The exterior looks like the other peaks: a jumble of rock and ice cut at angles only nature would have produced. The entrance is well-hidden and heavily guarded by crystalline golems, but a clever individual can sneak inside.

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.

The giants themselves are so few in number one can wander the halls without ever meeting one — which is probably for the best, since no one is 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 here 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.
