Stargate SG-1: Living Gods: Stargate System Lords
The Goa’uld leadership is formed from out of the early Unas tribal culture, lead by the Alpha Male, Atok. This leadership would rise to the first recognized Goa’uld order, fueled by the impressive physical forms and near-magical technology appropriate from ruins of the Ancients.
Apep decrees his underlords as his brothers and sisters in rulership, although he remains firmly in control. The underlords – Ra, Nut, Thoth and their servants Osiris, Isis, and Bastet – pledge their loyalty and, for a time, a single united leadership rules the Goa’uld. Thus united, the symbiotes sweep through the galaxy like a plague. Their numbers swell and the Unas are nearly wiped out – again too many larval Goa’uld are bred. In addition, the life of the Goa’uld is significantly lengthened, creating even more of a population problem. Apep continues the ancient practice of ritual cannibalism.
The Goa’uld, Thoth is able to create the first rudimentary sarcophagus by reworking technology of the Ancients. The device is primitive and powerful, able to sustain an Unas host for several generations. The device, however, exerted a terrible toll on the Goa’uld larval, as the sarcophagus introduced the mineral naquadah to the larva’s bloodstream and the Goa’uld queen are unable to prevent its transference to future Goa’uld larva.
Ra instituted himself as ruler of the Goa’uld, again taking on the leadership structure originally formed by Apep. For his part, Thoth is also banished, although his understudy, Telchak remained. Bastet is rewarded for her help against Anubis. Osiris and Isis joined the ranks of the Goa’uld underlords as well, and Anubis’ super weapon is dismantled. Ra took the six crystals that powered the device and divided them amongst the remaining loyal Goa’uld, knowing that his species’ pretty bickering would ensure that the weapon is never used again.
