Ba'al continued to play a minor role in SG-1 seasons 9 and 10, occasionally joining forces with the Earthlings, but ultimately remains evil. Even though the evil Goa'uld are killed off in season 8 of Stargate SG-1, one survivor remained, named Ba'al. Stargate: Continuum completes the story arc of a certain character that we know from Stargate SG-1. The effect of the Ark of Truth is that all Priors in the galaxy become aware of the truth and thus leave their religion and the Ori altogether, and the film ends with SG-1 preparing to go through the Stargate on yet another mission, implying the story will go on. The Priors are humans who serve the Ori and promote their religion, which includes plans to invade Earth.
The device shows the Priors that the Ori are not gods. The Ori gather their forces for a final assault on the Milky Way, but SG-1 activates the Ark of Truth, and it defeats the Ori, albeit in an unexpected way. But in the process, they also resurrect an old enemy - the replicators. Despite being a suicide mission, they visit the planet and retrieve the device. Naturally, the team is eager to find it, but unfortunately, it's on the Ori homeworld. The movie begins by explaining the existence of an ancient device known as the Ark of Truth, which can defeat the Ori. Ark of Truth wraps up the Ori arc left dangling in the SG-1 series finale, effectively eliminating the enemy once and for all.
