Stargate SG-1 follows and expands upon the Egyptian mythologies presented in Stargate. In the Stargate universe, the human race on Earth, known to the rest of the galaxy as the Tau'ri, were descendants of the Ancients, a race of highly evolved beings. Earth was believed to be the first planet where humans existed in this galaxy. Humans were enslaved and transported to other habitable planets by the Goa'uld such as Ra and Apophis. For millennia, the Goa'uld harvested humanity, heavily influencing and spreading human cultures. As a result, Earth cultures such as those of the Aztecs, Mayans, Britons, the Norse, Mongols, Greeks and Romans are found throughout the known habitable planets of the galaxy. Many well-known mythical locations such as Avalon, Camelot and Atlantis are found, or have at one time existed.
The series explores both long story arcs (discussed below) as well as more contained one-episode stories. Often these shorter stories will detail SG-1's exploits on a previously unexplored planet.
Presently, the Earth Stargate (found at a dig site near Giza in 1928) is housed in a top-secret U.S. military base known as the SGC (Stargate Command) underneath Cheyenne Mountain. Col. Jack O'Neill (Richard Dean Anderson), Dr. Daniel Jackson (Michael Shanks), Cpt. Samantha Carter (Amanda Tapping) and Teal'c (Christopher Judge) compose the original SG-1 team. Along with 24 other SG teams, they venture to distant planets exploring the galaxy and searching for defenses from the Goa'uld, in the forms of technology and alliances with friendly advanced races. Later in the series, some members of SG-1 leave and new members join, such as Jonas Quinn (Corin Nemec), Hank Landry (Beau Bridges), Lt. Col. Cameron Mitchell (Ben Browder) and Vala Mal Doran (Claudia Black).
The parasitic Goa'uld use advanced technology to cast themselves as gods and are bent on galactic conquest and eternal worship. Throughout the first eight seasons, the Goa'uld are the primary antagonists. They are a race of highly intelligent, ruthless snake-like alien parasites capable of invading and controlling the bodies of other species, including humans. The original arch-enemy from this race is the System Lord Apophis (Peter Williams). Other System Lords, such as Ba'al and Anubis, play pivotal roles in the later seasons. In the third season, the Replicators are also introduced. The Replicators are mechanical bugs that feed on metals to "replicate" and create more bugs. Enemy of the Asgard, they are the main reason why the Asgard cannot eliminate the Goa'uld threat. In the ninth season a new villain emerges, the Ori. The Ori are advanced beings with unfathomable technology from another galaxy, also bent on galactic conquest and eternal worship. The introduction of the Ori accompanies a departure from the primary focus on Egyptian mythology into an exploration of the Arthurian mythology surrounding the Ori, their followers, and their enemies — the Ancients. Both Ancients and Ori are Ascended Beings, meaning that they have 'ascended' to a higher plane of existence, giving them extraordinary powers.
