Author: KhaosNite

Rating: T for Teen

Genre: Action/Adventure/Humor

Summary: Earth and its Off world bases, face complete destruction from the Orin, and SG-1 (including Jack ), travel to Atlantis to save themselves.

Disclaimer: I don't own anything of Stargate, just this story plot, and the new commander of the Oddessy for my story, Colonel Dylan Shuttle.

Spoilers: SG-1 03-10 "The Pegasus Project" (Though very brief reference in this chpt.)

A/N: Crossover with Atlantis, AU, set at the end of S10. In this AU, Jack stays SGC commander and gets promoted after a years worth of base commander service to Major General, but no transfer. Which means No Landry involved. One last thing, any A/N I need to make during the story will be italics and in brackets.

Chap A/N: Introduction, and first look at the situation for the rest of the story. Atlantis team introduced, with a shocking revelation about the new lead Atlantis team. Read to find out what that is.

Previously in Stargate: Atlantis Infinity...

On board the Oddessy

"It'll be fine Carter, we just have to move on," Jack said in the sincerest way he could. Teal'C nodded, in agreement with his friend, "General O'Neill is right Colonel Carter, we must move on if we are to deal with the loss of Earth."

"Attention, this is the Captain. We are approaching Atlantis, and our new home."

And now...

Chapter 2

The Oddessy exited hyperspace, and started its approach to Atlantis. On the bridge, Colonel Shuttle was giving orders to the crewman on the bridge, and receiving replies about landing sites, and how long till they landed. SG-1, with Jack, entered the bridge, and stared out the forward window looking onto Atlantis. Daniel gave the same smile he had when SG-1 traveled to Atlantis to start their quest for the Sangrael. (Note in this universe events have proceeded almost parallel to that in the standard universe, with the exception Jack had made very similar decisions as to what Landry did in the series.)

Soon after their approach began, the voice of Doctor Weir came over the comm.

"Oddessy, this is Weir. General, as per your instructions, I haven't spread the news yet, and we are awaiting you all in the city shortly."

Jack turned to Shuttle, who open the comm lines to Atlantis. Jack smiled, and turned to his former teammates, and replied to Weir. "Doctor, I appreciate what you are doing for us. We will be landing within minutes, and I will prepare to tell everyone the news." Carter, still tearing over the loss, turned to Cam. He gave her a weak smile, knowing full well how the had felt over the loss. Teal'c and Vala, both were tearing up a bit, more so Vala then Teal'c. Surprisingly, Vala turned to Daniel, who was staring at her weirdly for a moment.

"So Daniel, do you think we can explore the city for its marvelous treasures?" Vala asked, in her usual happy voice. The entire team and Shuttle turned to face Vala, all giving her weird looks. Teal'c gave his weird, eyebrow thing.

"What? I mean since we are going to be spending the rest of our lives here, I mean we can certainly search for Atlantis' wondrous treasures," she said, replying to their looks.

Oddessy finally landed on one of the cities landing pads, also noticing the Daedalus was also parked. Jack gave the little hand signal to show his team to get ready to beam down. Everyone from the team, except Daniel and Jack had left the bridge. Daniel had stayed at the front of the bridge staring at Atlantis, wondering whether had he done anything differently in the past two years, this outcome would have been different. He finally had gotten what he wanted, which was a chance to stay in Atlantis, but he didn't want it to be under these circumstances.

Shortly thereafter, SG-1 beamed down to Atlantis' embarkation room, where Doctor Weir, and the Atlantis team, including Lt. Colonel Sheppard, Doctor McKay, Teyla, and Ronin, plus Doctor Beckett were waiting. Doctor Weir, smiled and walked towards SG-1, slowly stretching out her hand for a handshake with Jack. "Welcome back to Atlantis SG-1, I'm glad to see you are all ok," Weir said welcoming the team. Jack accepted the handshake, and nodding at her statement of the team being ok.

"You know SG-1 and I Elizabeth, we usually end our missions without that much of a scratch on us," he said sarcastically, "Now, I think its time we inform everyone of the bad news." Elizabeth nodded, and showed the rest of SG-1 upto the 'control room' of Atlantis.

Weir turned on all-city communications, plus opened comm lines with both the Daedalus and Oddessy and Jack walked upto the console. "Attention everyone, this is Doctor Weir. I'm sure you've heard the news the Oddessy has come to the city, with SG-1. Unfortunetly, they have some terrible news to tell us." Elizabeth announced. Jack nervously started to give the speech about Earth, as the doctor gave him the cue.

"To all members of the Atlantis Expedition, the war in the Milky Way with the Ori, has come to an all-time low. Less then two weeks ago, we received word the Ori had re-opened their connection with the Supergate, and sent a large fleet of their Warships to all our off world sites, and Earth. Now with the tremendous firepower from their super weapons, they destroyed each planet, by firing all at once, and with the strain of 12 Ori ships firing, tore the planets apart. Finally less then a week ago, the Ori fleet entered the Sol system, on a direct course for Earth. Now my team, and most of the SGC staff beamed onto Oddessy before they launched their strike, and managed to get away unharmed. The last we saw of Earth, before we entered Hyperspace was the Ori firing on Earth, and destroying it. It is with my deepest regret to inform you all our home, Earth has been lost. All our families, friends, and loved ones are gone. We are the last survivors of the human race. Before we left, we have managed to bring enough supplies from Earth to supply us for another year or so. After that, we will have to rely on trade with other races to substain us. I wish us the best in our travels, to help us grow and prosper here. General O'Neill, out."

Everyone in the city was very shocked to hear the news of Earth, but decided to block it out and continue their daily business. A few hours after the announcement, Jack met Weir in the briefing room to discuss the creation of Atlantis' new lead team. It took them an hour as to decide its members, and who was leading, but came out smiling. As Jack and Elizabeth exited the briefing room, they went to the mess hall, to find the two teams chatting. "Guys, me and Doctor Weir have an important announcement for all of you. SG-1, and your team Sheppard, are being shut down, as two seperate teams," Jack announced to his friends, and new 'co-workers'. Everyone looked up shocked at what was going on. But Elizabeth lifted her hand, as to finish Jack's announcement. "We have both decided to combine your two teams, and give a new title. From now on you will be known as SG-A, or Stargate-Alpha team." Everyone looked up rather curious as to the decision. What was curious enough was who had been decided to lead the newly formed team. Both John Sheppard, Sam, and Cameron all were the same rank, of Lt. Colonel so one of them leading would be very weird. They knew that neither Daniel, or Mckay were going to lead the team, or any of their alien friends.

"Now this is what is going to be suprising for all of you, as to who is leading you," Jack finished, "I am!" Everyone smiled, and was shocked in amazement, that the ranking officer in Atlantis would be leading them. "And despite me leading the team, I'm also going to be incharge of our military still. Now everyone rest up, Elizabeth has told me she has a surprise for us tomorrow from Dr. Beckett, that I hope will greatly help us here. Until then I will see you later."
