The Tok'ra homeworld is the location where the last of Ba'al clones, presumably the last of the Goa'uld System Lords was finally extracted from his host. SG-1, along with General Jack O'Neill, went to the planet to watch the ceremony. As the ceremony was being performed, Vala Mal Doran and Teal'c vanished. After them, the Tok'ra in the city and the city itself also began to vanish. Mitchell, Carter, and Jackson quickly rushed to the world's Stargate and dialed back to Earth. However, upon arriving on Earth they found themselves in an alternate timeline, where they learned that the original Ba'al was still alive and changing history. When Mitchell went back in time and killed Ba'al the timeline was finally fixed, and everything reverted back to normal. The last of Ba'al's clones was then extracted, finally bringing the reign of the System Lords to an end. (SG1: "Continuum")
