The Byrsa are a peaceful race who live on Cartago. They have learned to flee from the Goa'uld by running and finding shelter when the Stargate becomes activated. They have managed to escape the Goa'uld many times, although they can only run as fast as the slowest person, which makes them vulnerable. The people of the planet recognised Teal'c as the Jaffa that killed one of the inhabitants of the planet, and forced a trial to be held with Teal'cs life on the line. However, after another Goa'uld attack, the people realise Teal'c has changed, when he helps defend the planet from the Jaffa and Apophis.
