Teal’c is a Jaffa from the planet Chulak. In the decades before the events of Stargate SG-1, the Goa’uld System Lord Cronus executed Teal’c’s father (Cronus’ First Prime, the most senior Jaffa rank) for retreating during a battle that could not be won. In the hopes of avenging his father’s death one day, Teal’c joined the armies of the rival System Lord Apophis. Under the direction of Apophis’ then-First Prime, Bra’tac, Teal’c learned the ways of a warrior and rose in the ranks to become Apophis’s new First Prime. His interaction with Bra’tac and his own personal experiences eventually led Teal’c to doubt the divinity of the Goa’uld.
