It's the cliffs and caves where the dragons live, and the habitations necessary for their riders.
The dragons come in different colors. Green, blue, brown, bronze and gold. Canth is a brown. Bronzes fly the Queens in mating flights. The bronzerider whose dragon flies the Head Queen of the Weyr becomes the Weyrleader. My brother, F'lar, who is here too, is the Weyrleader of Benden. I'm his wingsecond.
