Gnome

History
The eccentric, often-brilliant gnomes are one of the most peculiar races of the world. With their obsession for developing radical new technologies and constructing marvels of mind-bending engineering, it is a wonder that any gnomes have survived to proliferate. No one knows much about the gnomes' history before dwarves discovered them; not even the gnomes know much of their own history prior to the Second War. Historically, there are some records of gnomes having contact with other races. There is the occasional historical documentation of individual gnomes having contact with humans and high elves in the northern continent of Lordaeron in Tirisfal Glades as early as 848 years. Apparently, the first gnomes that came into existence were "mechagnomes", small clockwork-creatures created by the Titans. It is unknown why the titans created them, though most likely they were created to help shaping Azeroth along with the earthen and the sea giants. What is known is that the mechagnomes, like many other beings created by the titans, were affected by the Curse of Flesh. This gradually turned mechagnomes into the fleshy variant seen today. Also for unknown reasons, this knowledge has been eluded/lost by the gnomish race. Information of this evolution can although still be found on various locations, gradually explaining how the gnomes appeared on Azeroth. One of the major sources of this info is Gearmaster Mechazod, a mechagnome found by normal gnomes in the Borean Tundra during the building of an airstrip. Not only does Mechazod confirm that the mechagnomes were created by a titan called "The Grand Architect" within Ulduar and that fleshy gnomes are a result of the Curse of Flesh's effect upon mechagnomes, he also possesses the ability to remove this curse and thus revert fleshy gnomes back to mechagnomes. Still, most normal gnomes would prefer he didn't. (Unlike Tol'vir and Mogu). Other traces of the gnomes' past can be found in the Storm Peaks which contains a large population of mechagnomes.
