With a new commander of the SGC comes a new leader of SG-1, Lt. Col. Cameron Mitchell, a former fighter pilot who flew an F-302 in the battle over Antarctica. However, he is deterred by the fact that all the other members of SG-1 are leaving for other ventures: Teal'c to manage the Jaffa Nation, Carter to Area 51 for alien RandD, and Dr. Jackson to Atlantis as an Ancient expert. Mitchell endeavors to keep the members of SG-1 for himself, but they are increasingly tough to convince. Written by trekkie4christ

Having solved the riddles put before them, Col. Mitchell manages to pull the sword from the stone and must fight a holographic knight in shining armor and with that - once they make amends for Vala's light fingers - the treasure appears. Daniel finds new information about the Ancients who have also been known as Alterans, Ancients who may not have ascended. Using the Ancients communications stones, Daniel and Vala find their consciousness transported across the universe where they occupy the bodies of a man and woman living in a medieval society. The locals worship the Ori, a religious cult that now learns of human existence. Written by garykmcd

Daniel and Vala have used the Ancient device to inhabit the bodies of people in the Alterans' home galaxy. They have been taken by a prior of the Ori to meet the Doyen, one who speaks with the Ori, their gods. Daniel surmises that the Ori are what the Alterans who became the Ancients left behind and have ascended in a similar fashion, but without the restrictions. Written by trekkie4christ

The Galarans visit the SGC to demonstrate a new learning tool they have developed. They have found a way to to graft memories - and the person's expert knowledge - from one person to another. The Pentagon thinks it could cut pilot training for example to just a few days and are definitely interested. Sam believes the Galarans are more than likely interested in acquiring arms in return and SG-1 is dispatched to the planet to see what they can learn. Mitchell spends the night with the scientist in charge of the project, Reya Varrick, but when she is found dead Mitchell is arrested - and he admits to having memories of having killed her. Mitchell is certain he didn't kill her and demands a complete investigation. Written by garykmcd

Sam however thinks they may have come from a parallel universe as the result of the black hole they created when they destroyed the Ori beachhead. As more SG-1 teams arrive from other alternate universes, one of them includes Dr. Fraiser and another includes the Tok'ra Martouf. It's left to Sam and Martouf to find a way to send them all home.

On a mission to trade in a promising corn type, SG-1 is taken captive by Worrel, a Lucian Alliance underling, who also holds them erroneously responsible when their stargate disappears (as on several planets). General Landry works on Nerus's appetite for food and freedom to find out that the thief is Ba'al, who plans not only the ransom but to start a new Goa'uld empire. After the Odyssea rescues SG-1, SGC and the Alliance try to take on Ba'al and each-other. Written by KGF Vissers

SG-1 is tasked to accompany members of the International Oversight Advisory, including Richard Woolsey, on a tour of the Gamma site. The visitors are suitably impressed but everyone is put in danger when a carnivorous insect escapes from the lab. The base is locked down and no one is allowed to travel through the gate. The bug is linked to the Ori - it's appeared on several planets that they've visited - and Daniel thinks it may be their follow-up to the virus. SG-1 and the IOA visitors take refuge in a cave but Gen. Landrey is left with little choice but to flood the planet with a deadly neurotoxin to destroy the bugs. SG-1 looks for away out before that happens. Written by garykmcd

Sam manages to activate an Ancients' device they found at the Glastonbury site and she and Mitchell are shifted into a phase that makes them invisible to everyone. Daniel soon figures out just what is going on but Dr. Lee's proposed solution sends Daniel to the same plane as Sam and Mitchell. There he is able to translate information explaining that Merlin had created a weapon against the Ori - and provides a gate address where it can be found. Meanwhile, Teal'c travels to a Jaffa planet that has sent out a distress call. The two events are related. Written by garykmcd

Using the Ancients communication technology Vala, who is in the Ori galaxy, contacts the SGC. She tells them that after being sucked into the wormhole she awoke in a bed in a village much like the one she and Daniel had visited when they used the communication stones. The locals think she fell from the sky - a gift from the gods - and befriends the gentle Tomin, a devout follower of the Ori who has a bad leg. Vala has two pieces of information for the SGC: first, she is pregnant though insists that she didn't have sex with anyone; and second, the Ori have been building a fleet of ships and building up its army. Meanwhile, Col. Chekov advises General Landry that the Russians will not be renewing their working agreement with the United States and will be taking their stargate. Written by garykmcd

Based on the information Vala gave them, SG-1 travels to the planet where Merlin may have hidden his secret weapon to defeat ascended beings. There they find an appropriately medieval village and learn that Merlin kept a library there. The locals have never been inside owing to a curse that on anyone who dares enter but SG-1 finds a way in. Once inside, they find a secret chamber that may reveal the location of the weapon. SGC meanwhile have located the Ori's supergate. Sam's attempt to get control of it is too late and four Ori make their way through. In the ensuing battle, much of Earth's fleet is destroyed and the future of several SGC members is left in doubt. Written by garykmcd
