Elf

From The unofficial Dark Sun wiki

Tall and long of limb elves are graceful, but untrustworthy beings to outsiders that live in the Now. Elves live in close knit tribal structures and are only loyal to members of their own tribes. There are several ocupations for the tribes, such as traders, riders, herders. Elves a nomadic people traveling the desert without the aid of mounts. They are capable of running for days on end. Elves never ride another animal, to do so is a sign of terrible weakness. They also 'run' as a tribe and any member of the tribe who cannot keep up is left behind. They rarely trust outside of their own tribe but when they do gain a level of trust for people outside their tribe they often test this trust by many different methods. For example they will feign injury to see if their person they trust will risk themselves to help them. Elves make horrible slaves.
