Halls of LightningIntroduced in Wrath of the Lich King
Upon departing Azeroth, the titans entrusted loyal protectors with safeguarding Ulduar, an enigmatic city nestled in the mountains of the Storm Peaks. Designated supreme among his brethren was the guardian known as Loken, but with the power of the titan complex in his hands, he turned to darkness and plunged the region into chaos.
The reasons for Loken's treachery and the fate of the other guardians remain a mystery, but there have been whispers of a great evil at work behind the fall of the titan city. For any heroes brave enough to seek out the truth, it lies within the corridors of the ancient compound. Thus far, however, few have braved the perils of Ulduar and returned to tell of their discoveries.
