So this takes place in season 9 of stargate SG1 with some minor changes, General hammond still runs the SGC and Jack is still part of SG1. It crosses over with Galactic during episode 206 just before Adama opens the tomb of Athena.
"Sir there is something you have to see!" Daniel Jackson whispered into O'Neill's ear half way through the briefing.
"This better be good!" Jack snapped in reply before excusing himself from the briefing and following Daniel to his lab.
Upon entering the lab Daniel pulled a very old scroll from his desk and unraveled it before the General. The markings sprawled over the surface were clearly ancient in Origin. What caught Jacks attention was a number of symbols that looked very familiar.
"A gate address?"
"Its more than that Jack! Look at how many symbols there are!"
Jack returned his attention to scroll and realized what Daniel was so enthused about. There were nine symbols written on the scroll.
"That's impossible" Jack replied "Gate address in our galaxy are only 7 symbols, gate address to another galaxy are 8, how on earth can there be nine symbols?"
"Think about it Jack, Sam used the telephone analogy when explaining the 8th cheveron lock that sent you to Othala. Now if 7 symbols are a local phone number, and the 8th cheveron makes up the area code, then the ninth symbol…"
"Is like a country code" Jack interjected.
"Exactly. Now I believe that this address is to a galaxy further away than anything we could even dream of. We're talking billions of light years!"
"We'll if that's true we'll never have the power to dial an address that far away"
"You're right about that, but we do have a gate that would have the power to reach it!"
"You mean Atlantis!"
"Yes, they have a fully functioning ZPM!"
"Okay, so even if they can dial this address, it'd be a one way trip. What would make it worth the risk?"
"How about ancient technology that could rival that of Atlantis!"
"What do you mean?"
"This scroll tells of a race of humans that inhabit a planet called Kobol. Now Kobol was a world where humans and ancients lived together. The ancients shared their technology freely and together both races advanced to the highest levels of technology the universe has ever seen."
"What kind of technology are we talking about here?"
"Well for example, the ancient-human alliance developed a new way of traveling through space. They called it, loosely translated, faster than light drive. It could travel the span of entire galaxies near instantaneously. Like the stargate, the distance it could cover was only bounded by the amount of energy they could produce. They also had the ability to create entire worlds from scratch, and their ships had power sources that were a thousand times more powerful than the ZPM."
"Okay so they are a little more advanced than Atlantis, but if they are so advanced why is there no reference to them in the Atlantis database?"
"Well that's the thing, the Atlanteans originated from Earth, and the Altarians originated from Avalon. But the Altarians and the race of Ancients from Kobol came from the same Home World which they fled many eons ago. The Altarians terra formed Avalon whereas this race of Ancients terra formed Kobol."
"Well, if that's true, then how did this scroll get to this outpost?"
"That's the good part. We always assumed that the ancients were the original Latin and Greek gods. That they were the builders of roads… I don't think that's true anymore. According to the scroll, the Ancients of Kobol heard a cry from their brethrens. It was probably a distress signal sent out during the plague"
"But the plague happened millions of years ago!"
"Exactly, if Kobol is as far away as I believe, then it would take millions of years for a signal to reach Kobol. Aproximately five thousand years ago a group of humans along with a handful of ancients made the journey back to Earth by stargate. Now they knew that they would be to late to save their brothers from the plague, but they had another reason for coming to Earth. Apparently their society had become fractured into 12 specific tribes, or races. Those that came to Earth were a compendium of all 12 tribes who opposed the segregation of their species."
"Great then, why don't you get to Sam, see if she can plot our exact destination and the energy requirements we'll need from Atlantis, while I go dial up the Asguard and see if they can be of any help!"
"Okay Jack"
Samantha stood before a star chart in the briefing room. Jack, Teal'c and Daniel sat patiently.
"Well, as you can see, the destination point is 281.783 billion light years away. Sir I don't think Atlantis has the power requirements for a journey that far!"
"What do you mean?" Daniel interjected "They have a ZPM!"
"Well, yes a ZPM provides a lot of energy but it's far from the ultimate power source. The energy requirements for gate travel are directly proportional to the square of the distance between the two gates. By my calculations, simply establishing the connection will require 25 of the ZPM's total power reserve. After that it will require an additional 4 for every second the gate remains open."
"And with the Wraith threat to Atlantis that's a level of power we can't part with… even with the potential gains" Hammond stated.
"Hold it, I just got off the phone with the Asguard. Thor's on the way!"
Just as the words left Jacks mouth the brilliant glow of the Asguard transport beam filled the room, depositing the unmistakable form of Thor.
"Greetings" Thor stated in his cheerful voice.
"Thor good buddy! Its great to see you again… so is there anything you can do to help us?"
"We are as interested in the revelation of another Ancient civilization as you are. The Asguard High council has already agreed to divert whatever resources are required to reach Kobol"
"That's great, so are you going to give us a couple ZPM's?"
"Unfortunately the physics behind the zero point module, as you call it, are beyond our technological capabilities."
"But you must have a power source that can establish a connection?"
"None that could provide sufficient energy to reach Kobol by stargate. We have, however, completed a new class of vessel that can travel to Kobol within a years time"
"Wow, that's got to be one hell of a vessel!" Carter stated.
"It is a left over from the replicator war. When all hope was lost we believed our only course of action was to develop a hyperdrive capable of outrunning the replicators. The project was put on hold after the discovery of the android Reese, however, given the defeat of the replicators many projects have been reopened, and completed."
"Cool, so when do we get one of these drives for the Prometheus?"
"Unfortunately the drives power requirements are beyond your capabilities at the moment. It would be useless to you."
"Wait a minute, what kind of energy requirements are we talking here?"
"If you are thinking of tying the hyperdrive power core to the stargate, we have already considered it. Unfortunatly short of an uncontrolled overload, it would not provide sufficient energy to initially open the connection."
"Um, Thor, I have a question… would a singularity provide the energy requirements to reach Kobol by stargate?" Daniel asked.
"Yes, however the gravitational sheer of the blackhole would destroy a vessel before it gets close enough to access the energy to open the gate"
"What about a micro singularity, formed by the collapse of a planet roughly the size of earth?" Sam asked.
"The energy requirements would be sufficient, but even the Samantha Carter cannot survive the gravitational sheer for more than a few minutes"
"Then that's its sir, we transport the gate aboard Thors vessel and use the singularity the Priors created to gate to Kobol"
"And then we'd have to wait a year for the Asguard ship to drop by and pick us up"
"What if the Ancients aren't home? What if they moved to another planet?"
"You could take an Atlantean puddle jumper" Thor suggested.
"Um, the puddle jumpers don't have hyper drives"
"I am willing to modify your puddle jumper with Asguard technology" Thor interjected.
"What kind of modifications are we talking here?"
"Hermoid has been studying the ancient technology on Atlantis extensively. Combining Asguard technology, he believes that the puddle jumpers have great potential. The puddle jumpers power core utilizes a micro form of zero point module capable of being recharged. Combining this core with a miniaturized neutrino ion generator, the core can be kept at full power indefinitely. The Ancient drive pods can be modified to accommodate a hyperspace window generator, shield generator, and the forward and aft sections can be equipped with Asguard weapons."
"Well that'd be one hell of a replacement for the x-303"
"How long would these modifications take?"
"Several days, however, we have a prototype completed and stored aboard the Samantha Carter as we speak"
"Okay lets go over this plan one more time!" Jack ordered. He was currently aboard the Thor's vessel, standing inside a modified puddle jumper looking at a stargate Thor had managed to fabricate out of thin air.
The puddle jumper, although retaining the basic shape of the Atlantian jumpers, was a brilliant white color and significantly longer than its predecessor. The interior was also a lot more spacious. The outer walls had the ability to expand and contract, altering its shape for hyperspace flight or stargate travel. When expanded the extra rooms were partitioned off allowing for living quarters, and bathroom facilities. It was basically a cargo ship that could morph for gate travel.
"With shields at maximum power, this vessel can enter the time/space distortion field of the micro singularity, and get close enough to use it to power the stargate." Thor stated.
"We would then send an asguard probe to make sure it was safe, and scan for energy and life signatures on the planet or in orbit. Depending on the results of the scan we will then decide if it is worth proceeding." Carter continued.
At that moment the ship shook violently.
"What was that?" Jack asked.
"We have just entered time/space distortion field of the singularity. Shields are holding at full strength, however we may have a minor problem"
"Minor problem?"
"The Mass of the singularity has increased by over 27 percent, as a result the gravitational sheer will be greatly amplified."
"And that's a minor problem?" Jack stated sarcastically.
"We have reached optimal range to initiate dialing sequence!"
Almost immediately the pasty white and ultra thin stargate began dialing the coordinates left behind by the 13th tribe of Kobol. After the lock of the ninth chevron the familiar blast filled the room directly ahead of them. From out of nowhere a probe fabricated itself in front of the event horizion and entered.
"The probe is on route!" Thor announced as a massive shudder gripped the ship. "We are experiencing a massive gravitation sheer, shields are down to 64 percent and holding."
"A couple more like that and this ship is toast!" Daniel commented.
"The probe has reached its destination" Thor announced. He extended his arm in which a green stone appeared. Waving his free hand over the stone a holographic image appeared before Thors command seat. It was a 3 dimensional image of the scene the probe had exited onto. There were trees surrounding the clearing in which the stargate stood alone. The image seemed to zoom out to a topographical survey of the surrounding area.
"Whats that?" Jack asked, pointed at several red dots that appeared on the survey.
"They appear to be human life signs O'Neill" Thor responded. "I am also detecting a vessel of some sort" Just as the words left his mouth a 3 dimensional image of a raptor appeared next to the topographical map. "The vessels technology is only slightly more advanced than your own… however its fuel source is indeterminate… it appears to be a derivative of naquidah, but that cannot be confirmed. Also…" The image changed to reveal a strange contraption "this object is attached to primary engines, its technology is indeterminate, it may be the FTL drive the scrolls told of".
"Then they are defiantly worth making contact with!" Daniel almost shouted with enthusiasm.
"Woe there big fella" jack interjected "We aint traveling billions of light years for a handful of humans and a shuttle that's only slightly better than something we have!"
"Then this may warrant your mission" Thor interrupted. The topological map had zoomed out to reveal what appeared to be very large vessels in orbit of the planet. "Long range sensors also indicate several more capital class vessels in the expanse outside of the star system"
The ship shuddered once again, this time much more violently. The event horizion of the stargate seemed to fluctuate wildly. "You must go now, Shields are at 12 percent and I am detecting several haul fractures! The Samantha Carter will not survive another hit"
On instinct Jack jumped into the pilot seat just as thor's command chair was transported off the jumper. "Okay everyone here goes!" He shouted as the puddle jumper lurched towards the stargate.
