SG-1 travels to planet with the gate address found in the episode 'Arthur's Mantle' to find the Anti-Ori weapon. There they discover a pre-industrial village. In the Camelot town square, as the town is known by on the planet, they find a sword in a stone. Upon talking to the villagers, they learn that Merlin had a library or sanctuary in the town, too. The problem is the curse on the library. Anyone entering the library winds up dead at the hands of the Black Knight defense mechanism. Mitchell will have to fight another Knight in order for them to gain entrance. The search for the weapon is interrupted by news that a new Ori super gate has been detected. The teams split in to two's with Jackson and Mitchell returning to search for the weapon, and Carter and Teal'c joining the Odyssey, which is on its way with all the ships that can be mustered, to try to destroy it. Can the super gate be destroyed in time? If not, can Merlin's weapon be found in time, if the Ori do make it through the super gate before it is destroyed?

Stargate SG-1 Show Summary

Step through the Stargate with SG-1, a team of soldiers and scientists, as they travel instantaneously to other planets to explore, forge alliances, defuse crises, establish trade, investigate ancient mysteries and defend Earth from such hostile forces as the Goa'uld and the Replicators.

For eight years, from their base at the U.S. Air Force's Stargate Command in the Rocky Mountains, Colonel Jack O'Neill, Dr. Daniel Jackson, Lt. Colonel Samantha Carter and alien warrior Teal'c have braved everything that the universe has thrown at them, from interstellar war and evil twins to passing and ascension.

But changes came to SG-1 as it began its ninth year of fearless service to Earth. New faces joined the team, as Lt. Col. Cameron Mitchell tries to fill the very big shoes of former SG-1 leader O'Neill, while General Hank Landry must adapt to the unique challenges of running Stargate Command, a posting unlike any other the military has to offer.

Offworld, SG-1 might have new friends - or new foes - in Vala, a former Goa'uld host turned freedom-fighter; and Gerak, a Jaffa leader who vies with Teal'c for political control of the new Jaffa nation.
