Ant-kinden — Art by David Mumford
The military power of Ant-kinden city-states has dominated the Lowlands since the revolution. Using their Art to link minds, to fight and work together with flawless discipline, they would have conquered the world by now, save that they reserve their most abiding loathing for Ant-kinden of any other city but their own. Renegade Ants, those who wish to do anything other than follow orders, live bitter, lonely lives cut off from the minds of their fellows.
OK, there are 4 Ant-kinden cities in the Lowlands: Sarn, Kes, Vek and Tark.
Sarnesh Ant-kinden have light brown skin and straight black hair. Kessen have warm-bronze skin (and apparently black hair). Tark are very pale (and have blond hair?).
So, what do the Vek and the outliers of the Tsen look like?
