The nahr were one of the first races of the Children of Thetan to walk the world. They are similar to humans in appearance, though taller and much more slender. The nahr have a dynamic history, which has left the race divided into four tribes: the alev, hava, kara, and sular. Each of the four tribes reveres and in many ways reflects one of the four elements. The names of the tribes are the nahren names for the four elements: alev (fire), hava (air), kara (earth), and sular (water).
