Age of Prata
Jaffa term equivalent to puberty, a time at which the ceremony of implantation occurs and a young Jaffa receives his or her first prim'tah (larval Goa'uld symbiote). If one is not given, the child will die, as many Jaffa groups have been genetically engineered to become dependent on symbiotes.
Bloodlines - Teal'c, knowing Rya'c has reached the Age of Prata, sets off to Chulak to prevent his son from becoming a slave.
Birthright - Ishta and her Jaffa resistance embark on raids to capture symbiotes whenever one of their children reaches the Age of Prata.
