Goa'uld Queen (Core Rulebook) was the Goa'uld queen on Dakara who created the Jaffa.
Biography[]
When the first human devotees were taken to her, she saw great potential in them as incubators for her children. She changed the human genome and engineered a fatal failure into the Jaffa's immune system that is triggered during the age of Prata, which was roughly the time of puberty. This made implantation of a symbiote required and left Jaffa hosts reliant on the Goa'uld for survival. (RPG: "Core Rulebook")
