Gelbin Mekkatorque is known as much for his technical brilliance as he is for his just leadership of the gnomes. In addition to being elected high tinker, the most prominent rank in gnomish society, Gelbin proved himself to be an inventor without equal by leading the construction of the Deeprun Tram, which links Stormwind and Ironforge. Yet all of the high tinker's achievements have been overshadowed by one catastrophic event that occurred under his rule: the fall of Gnomeregan.

Around the time of the Third War, an ancient menace known as the troggs surfaced in Gnomeregan from the depths of Azeroth. This barbaric race, thought to have been unintentionally released during the Uldaman excavation, crushed the gnomes' defenses and became entrenched in the lower sections of the city. Gelbin, for all his genius, was at a loss for a way to eradicate the savage invaders until his chief advisor, Mekgineer Sicco Thermaplugg, proposed that they inundate Gnomeregan with toxic radiation.

Confident in Thermaplugg's radical plan, Mekkatorque gave the order to irradiate the city. This bold move worked at first: toxic radiation spread throughout Gnomeregan and momentarily stopped the troggs' incursion. Soon, however, it was evident that the radiation was killing gnomes as well as troggs. In the end, nearly eighty percent of the gnomish race died, and many of those who survived were mutated into deranged leper gnomes. To add to the tragedy, the troggs then resumed their assault on the city.

Mekkatorque and the healthy survivors evacuated Gnomeregan and were taken in by the dwarves of neighboring Ironforge, but Thermaplugg disappeared. The high tinker later learned troubling news that his former advisor had seized control of the toxic gnomish city and instated himself as its twisted overlord. Much to Mekkatorque's shock, he also discovered that Thermaplugg had secretly desired the office of high tinker and might have been previously aware of or even complicit in the trogg invasion.

The immense loss of life at Gnomeregan weighed heavy on Mekkatorque's shoulders, and in his fury he ordered the death of Thermaplugg. A band of heroes took up the mission and returned with a tale of victory, but after analyzing the claim, Mekkatorque realized that the mechanized overlord defeated in the depths of the city was likely nothing more than a cleverly engineered facsimile of Thermaplugg.

Aware that defeating his nemesis would require a more robust approach, Mekkatorque labored over strategies to retake his city. His tireless brainstorming recently paid off with Operation: Gnomeregan, a brilliant multi-phased assault plan to liberate the gnomish capital and bring the real Thermaplugg to justice. With the operation set to begin, resourceful gnomes such as "Doc" Cogspin, Captain Tread Sparknozzle, and Drill Sergeant Steamcrank have been overseeing preparations and fine-tuning new technology that will be vital to the offensive.

Meanwhile, Mekkatorque has begun rounding up all able-bodied gnomes to join in the attack, and his call to arms has also been heard by other members of the Alliance. The gnomes' techno-savvy has been vital in past conflicts, and many Alliance heroes are likely to join the offensive to recapture the extraordinary inventions within the fallen city. For Mekkatorque, however, his plan goes beyond just reacquiring lost technology. The retaking of Gnomeregan will determine his legacy in history, either as the high tinker who lost the gnomes' beloved capital, or the one who reestablished it as the center of innovation on Azeroth.

Operation: Gnomeregan is now.
