A technical marvel, the subterranean city of Gnomeregan is wrought-iron evidence of gnomish brilliance, ambition, and ingenuity. It was carved into the stony foothills of Dun Morogh, and winds deep into the heart of the land. From their wondrous techno-city, gnomes provided invaluable support in weaponry, vehicles, and energetic troops to the Alliance of dwarves, humans, and high elves. Currently a battleground between the founding gnomes and the traitor Sicco Thermaplugg, the once-gleaming metal hallways of this labyrinthine city are slowly being retaken.[1]
Architecture of Gnomeregan

Gnomeregan [noʊmɹəˈgɑːn] was the capital city of the gnome race until a trogg invasion led to its tragic downfall. In a desperate attempt to kill the troggs, their ruler, Gelbin Mekkatorque, on the advice of his advisor Mekgineer Thermaplugg, detonated a radiation bomb in its halls, but only succeeded in corrupting whatever gnomes that remained - and empowering the victorious troggs.[2] 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.

The city is currently a mid-level dungeon. 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 [Hydrocane] rare staff which drops from an early mini-boss, Viscous Fallout. 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.


It wasn’t until their discovery by the dwarves centuries later that gnomes were recognized as a viable and important race. The dwarves were impressed with the ingenuity and quickness of their smaller “kin” (for they had also been titan-forged and similarly cursed), and they assisted the gnomes in constructing a capital city, Gnomeregan, in the foothills of Dun Morogh near the dwarves’ own capital of Ironforge. From their wondrous techno-city, gnomes provided invaluable support in weaponry, vehicles, and energetic troops to the Alliance of dwarves, humans, and high elves.[1]

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.

From Blizzard's Official World Dungeons site:

The last tunnel, leading into the Tinkers' Court.
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.

In Gnomeregan's heyday, inventors would compete for status by pitting their creations against one another.[3]

Operation: Gnomeregan

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.

Cut Short

Gelbin has determined that after the city has been retaken, it will be due for a major remodeling to make a more open, airy layout.

In Cataclysm

Cataclysm This section concerns content exclusive to 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.

Engineers will likely be interested in this instance as the large number of mechanicals means there is a chance of getting the [Fused Wiring] needed to make [Goblin Jumper Cables]. They also drop a number of schematics, even a few of the rarer ones.

  • Once, all the cloth and leather were vaporized by Fimble Finespindle's cousin.
  • Also known as GR, Gnome, and Gnomer. Pronounced Gnome-ruh-gahn.
  • Despite many allusions to it, there are no repair facilities available to players here.
  • In the Clean Room, [Grime-Encrusted Objects] can be washed in the Sparklematic 5200s for random junk, and sometimes green necklaces or rings. Since the area is filled with Alliance-friendly NPCs, Horde players will have to fight their way in. Alliance players can rest safely here; you can empty your bags at the merchant, and use the mailbox. Also, if you are Alliance, you can draw nearby mobs in, and, if you take damage, the Holdout Medics will buff you with Fortitude, and may even heal you with Renew.
  • Throughout the instance, there are Matrix Punchograph 3005 machines that will give you a list of binary numbers. The messages that are translated from these machines include "Short and sweet" and "Down with the horde!"
  • Beware of roaming Mobile Alert Systems; if not destroyed quickly, they summon mobs that drop nothing.
  • The Arcane Nullifier X-21s buff themselves and others with a shield that reflects magic back to the caster. Watch for it, and suspend casting until it disappears.
  • The Dark Iron Agents near the end are some of the deadliest NPCs in Gnomeregan. When they drop land mines, attack these immediately! They have only 200 hp, but they inflict over 400 damage on everyone nearby. Assign someone to destroy them and make a macro to target them.
  • There is a back door into Gnomeregan that is locked with a level-150 lock. Before Patch 4.0.3 it could be opened with the ([Workshop Key], dropped by the Electrocutioner 6000).
  • This dungeon was rarely run by Horde groups (prior to the LFG tool), and some of the dropped items are coveted by level-29 twinks, which makes some of the BoE drops as well as the [Discombobulator Ray] very lucrative on the Auction House.
  • When Emi Shortfuse tells you she's going to blow up the side tunnels she opened, get out of those side tunnels — if you are in one of those side tunnels, you will get crushed or trapped by the falling rocks, and your corpse may be too far away behind the rocks for the healer to resurrect. Likewise, if you want to loot all the troggs, pull them out of the tunnel before killing them; Emi will detonate before looting can be completed, so anyone looting bodies in the tunnel will either be trapped or killed.
  • There seems to be tracks similar to the Deeprun Tram running from the east wall of the aptly named Train Depot (now the Loading Room) to right before the Tinkers' Court. A line seems to have also go into the destroyed hallway off of the Hall of Gears. No cars can be seen at any point on these tracks. It is unknown how, or if, the Loading Room (now the Old Dormitory) was able to load any cars from its position, presumably with the arm that was there.

Patch changes

  • WoW Icon 16x16.png Patch 1.3.0 (2005-03-07):
    • Capped at ten players.
    • Lengthened the respawn time of many of the creatures in Gnomeregan.
    • Doors requiring the Workshop Key can now be opened with a  [Small Seaforium Charge].
  • Patch 0.10 (2004-09-18): Added a third Sparklematic 5200 to Gnomeregan, and fixed the issue that had both previous ones animating at the same time.
  • Patch 0.7 (2004-06-15): Opened and itemized as a level 24-33 dungeon.
