Gnomeregan

Gnomeregan was the capital city/kingdom of the gnome race until a trogg invasion led to its tragic downfall. In a desperate attempt to kill the troggs, their ruler, on the advice of advisor, detonated a radiation bomb in its halls, but only succeeded in corrupting whatever gnomes that remained - and empowering the victorious troggs.

The city is currently a mid-level dungeon. A few loyal gnomes still left in the city fought desperately to keep the troggs at bay. Their ruler, thought by certain gnomes to have abandoned them, eventually sent a rescue force of adventurers on a recon mission. They slew many troggs and ended up killing Mekgineer Thermaplugg and his rebellious gnomes. With their help, and the countless efforts of the gnomes who remained in Gnomeregan was retaken at the beginning of the Cataclysm and will stand as a bastion of defense against many foes, The Horde - The Burning Legion, The Scourge and Deathwing the Destroyer's forces. Gnomeregan is unique in that it contains an Alliance-friendly NPC section inside the dungeon itself, including vendors, guards, some new quests, and even a mailbox.

Gnomeregan is also unique in that it has a very technological, albeit comical, theme. Also notable is the rare staff which drops from an early mini-boss,. The staff allows permanent water breathing, and is used even by very high-level characters for this. The staff is thus situationally useful to all classes that can equip staves.

History
From WorldofWarcraft.com:


 * When the war against the Burning Legion ended, the Alliance discovered the reason for the gnomes' sudden withdrawal. Apparently, an ancient, barbaric menace had risen from the bowels of the earth and invaded Gnomeregan.  Knowing that their allies' priority was defeating the Burning Legion, the gnomes decided to make their stand alone.  Though they fought valiantly to save their beloved city, Gnomeregan was irrevocably lost.




 * 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,  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,, 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.

Prior to the Shattering, the gnomes, with help from the Alliance, launched an assault on Gnomeregan in an effort to liberate its lost capital, code name: Operation: Gnomeregan. The operation was successful, as they were able recapture Gnomeregan's surface and part of the city, an area they have named New Tinkertown. The gnomes seem to be gaining ground in the city as new gnomes assist in the defeat of the lepers on the surface of the city and the killing of one of Thermaplugg's most important lieutenants.

In Cataclysm
The city is turned into a war zone between the Gnomeregan Exiles and the leper gnomes. Gnomeregan is now the starting area for gnomes, and its quests will be centered around reclaiming the city and trying to force all of Thermaplugg's forces out. New gnome players start out as irradiated, and through a series of quests they cleanse themselves before permanent damage can be done.

The dungeon itself is largely the same, but most of the original quests have been removed. Instead, players assist the S.A.F.E. organization in a new quest line that is obtained from within the instance.
