The cult known as the Brotherhood of Wire and Bone was established by Fyzen Gor; its members included his initial group of twelve medical droids that were improved with organic limbs. A number of organic beings became members of the cult, one of whom was Ruas Fastent, a former Imperial Admiral. While the cult began on Utapau, Gor's home world, they had relocated to the Imperial asylum located on Grava by the year 7 ABY.
