Gnomes.

Overview
Gnomes are a near most Mythical race, spoken as a Faerie tale by Mothers and their Children, yet from my research and field expeditions, they may be more Fact than fiction.

Appearance
Gnomes, are, from ancient texts, described as short, stock figures, who looks much like short Elves, from what some ancient scholars hypothesized. Other than that, their appearance is unknown aside from being shorter than Dwarves.

Culture
Gnomic Culture is almost completely unknown, aside from a few structures discovered in near most complete ruins (and oddly enough constructed in ancient Elvish style), and a few artifacts, varying from enchanted staffs to swords that appear to be light-forged in nature which are under heavy guard and constant research by the Colleges, Both magical and Academic, there is almost no known trace of any permanent gnomic settlement. It is commonly believed by the Academia that they were a industrious society with technological capabilities far beyond our own

Disappearance
The time when gnomes disappeared is near most completely unknown, at a guess sometime between the human settlement of the imperial lands and the formation of the Early Kingdoms preceding the Solidification of the Empire, some several thousand years ago, else wise how could their ruins come into such disarray?
