Sistra, a purple granite peak, stood among numerous others on the moon Yavin 8, serving as the location of a city inhabited by the Melodies. Pools, caves, and extensive caverns characterized this mountain's landscape. These water-filled areas served as the habitat for mature Melodies, the Elders, while the younger generation of the Melodie culture—those awaiting their changing—dwelt in the caves and caverns surrounding these pools.
