Teyla Emmagan is the leader of the Athosians, a human race of farmers, hunters, and traders from the planet Athos in the Pegasus Galaxy. She is the daughter of Tagan. The Athosians are the first natives of Pegasus whom the Atlantis Expedition encounters on their scouting of potential evacuation sites in "Rising". After a Wraith attack on Athos, Teyla and the Athosians settle in Atlantis. Friction in "Suspicion" causes the Athosians to leave Atlantis and settle on the mainland. Teyla stays with Sheppard's team, but later helps with evacuating the Athosians from the mainland several times in the face of various threats.
