The only reason they appear in any numbers is because of some long-ago treaty forged by an unknown Tan Ktholian Emperor and the leader of the dyadherel as the semi-nomadic Elven tribe are called in their own language. It was dug up in the greatest hour of need - the Kulian Invasion. Having found the document, a runner was immediately dispatched into the deserts and wastelands to find the Desert Elves. He wasn't seen again until the final battle, accompanying a troop of dark-skinned Elven warriors.

Basically the treaty said that no more war would be waged between the dyadherel and the Tan Ktholian Empire. Obviously the numbers of the desert elves had been greater then. In return, each had to come to the other's military aid when required.

As the force of elves has been used only twice since then, to aid in crushing powerful rebellions, knowledge of the dyadherel as fighting companions is small. They normally fight with two swords, and appear to be equally good with both. Most wear some kind of basic hide armour.

They are disciplined, although they appear to have no leader. They seem to work well in a group or individually, and their main assets are speed and agility, often dancing away from a blow to land one on the next person. A few are known as the mori-dyadherel, beserkers affected by some blood rage. They go into a trance at the sight of battle, and can perform amazing feats of both weaponry and agility. One survivor from the Kulian Invasion mentioned one leaping over a whole block of warriors, three lines deep. Another told of unusual weapons, such as a curious three-bladed sword, being wielded by such warriors.

From what we have seen since, such tales are far from unbelievable.
