- "Blessed are those who follow the path in unison."
- —Prior speaking to Tomin
He healed Tomin of his limp, but did not heal him of the infertility he suffered from. In the days leading up to the Ori Army's departure from the Alteran Home Galaxy for the Milky Way, he told Tomin that he was not the father of Vala Mal Doran's child, but that instead, the child was the will of the Ori. (SG1: "Crusade")
After the child's birth, he informed Vala Mal Doran that her daughter was the Orici, who would lead the Ori Army in the Milky Way. He also stopped Dr. Daniel Jackson from killing Adria, but Daniel and Vala were still able to escape the Ori warship he commanded because his ship had lowered its shields when it landed on Chulak allowing the Odyssey to beam them out. (SG1: "Flesh and Blood")
He later returned, leading the Ori Army to the planet where SG-1 tracked the Sangraal to. He preached to the masses there and traveled with Adria to the various planets she tracked them to. He did not follow her to the last planet for some reason and was thus not killed with the rest of the soldiers by Dr. Daniel Jackson. (SG1: "The Quest, Part 1", "The Quest, Part 2")
He returned once more, coming to Earth in an attempt to be allowed to preach to the people of Earth to turn them to Origin, threatening that an Ori ship would come to Earth if his offer was refused. Major General Henry Landry told him that Earth wouldn't be so open, suggesting that the Priors had left Earth alone for so long because they knew that Earth may be able to resist a physical attack, and held him captive at Stargate Command until SG-1 returned. With SG-1's mission complete, they returned the Prior's staff and exposed him to the power of the Ark of Truth. This revealed the truth to him, and it was spread through his staff to the other Priors in the Milky Way galaxy and their followers, ending the crusade. (Stargate: The Ark of Truth)
