The Ori send a Prior to a world inhabited by free Jaffa. When the Jaffa refuse to accept the way of Origin, the Prior erects a force field around himself and the Stargate. A minor Goa’uld named Nerus makes contact with Stargate Command. His observational satellites over the Jaffa world are but one of his technological innovations, and he offers his assistance against the Ori. He provides intelligence that indicates the field is expanding and that somehow, the Ori are keeping the Stargate open indefinitely. Vala warns Gen. Landry not to trust any Goa’uld. But when the Jaffa high council does not respond to his messages, Landry feels Earth must do something to stop the Ori incursion. He sends Mitchell, Jackson and Teal’c to rendezvous with the Prometheus and then make contact with the Ori. Mitchell has orders to use any means necessary to stop the Ori, which includes using the Mark IX, a naquaddah-enhanced nuclear device capable of destroying a Stargate. Landry requests, and is granted, Carter’s assistance on the mission. Vala reluctantly joins as well because although the effects of the Goa’uld bracelets are weakening, she and Daniel still suffer ill effects when separated.
Mitchell delivers the ultimatum to the Prior. While the team is on the planet, Gerak arrives with a fleet of Jaffa ships to bombard the forcefield. Col. Pendergast aboard the Prometheus gets Gerak to stop in order to beam the team back aboard, but Gerak is upset at losing the element of surprise and at the humans’ seeming inactivity. Shortly thereafter, the Mark IX detonates. But the Stargate is not destroyed, and the force field expands more rapidly. Gerak resumes his bombardment and demands that the Prometheus join the assault. Mitchell authorizes the ship to do so, until Carter realizes that the force field is drawing upon the energy involved to fuel its expansion. Furthermore, the planet itself is collapsing. Carter theorizes that the Ori are using a black hole in their galaxy to power the wormhole, and are now forming one in the Milky Way to add power on both ends. Nerus has lured them into providing the Ori the power necessary to establish their beachhead. And now, unless the team can stop them, they will build a giant gate in space, capable of transporting a full-scale invasion fleet from their galaxy to ours.
