WOW Zone:Gnomeregan  

From Blizzard's Official World Dungeons site: Located in Dun Morogh, the technological wonder known as Gnomeregan has been the gnomes' capital city for generations. Recently, a hostile race of mutant troggs infested several regions of Dun Morogh - including the great gnome city. In a desperate attempt to destroy the invading troggs, High Tinker Mekkatorque ordered the emergency venting of the city's radioactive waste tanks. Several gnomes sought shelter from the airborne pollutants as they waited for the troggs to die or flee. Unfortunately, though the troggs became irradiated from the toxic assault - their siege continued, unabated. Those gnomes who were not killed by noxious seepage were forced to flee, seeking refuge in the nearby dwarven city of Ironforge. There, High Tinker Mekkatorque set out to enlist brave souls to help his people reclaim their beloved city. It is rumored that Mekkatorque's once-trusted advisor, Mekgineer Thermaplugg, betrayed his people by allowing the invasion to happen. Now, his sanity shattered, Thermaplugg remains in Gnomeregan - furthering his dark schemes and acting as the city's new techno-overlord.

Gnomeregan was the capital city of the gnome race until a trogg invasion led to its downfall. In an attempt to stop the invasion, their ruler detonated a radiation bomb in its halls.

One thing that makes Gnomeregan unique is that it possesses a friendly NPC section inside the dungeon itself, including vendors, guards, a repair station, some new quests, and even a mailbox.
