I'm thinking more along the lines of Cleyran. The garbs that are being worn are indicative of living in a very sand stormy place. Much like the Cleyra living conditions.
The town of Cleyra is surrounded by a sandstorm, protecting them from harm. The sandstorm is powered by a one of the four fragments of a Summoning Jewel. The Cleyran people were originally Burmecians, but, following a disagreement over the Burmecians' taste for war, the Cleyrans distanced themselves from Burmecia. Which again is exactly what's taking place with this new race. They are distancing themselves once more from harms way.
