Sartorus was a planet in the Milky Way galaxy that contained a Stargate, part of the Free Jaffa Nation. The world was once home to thousands of free Jaffa, who recently renounced their System Lord. One day, a Prior of the Ori came to this world and offered and pressured the inhabitants to worship the Ori. However, the people refused, so the Prior put his staff on the ground, causing a devastating Earthquake that leveled the city. Only a handful of Jaffa escaped the planet alive. (SG1: "Babylon")
