A/N: This is a little something I've been working on since Stargate Universe was cancelled. I'm not big on cross-overs, but I found what I think is a plausible idea and ran away with it. It's been a few years since I started and I'm not done, but I thought I'd throw it out there and chuck some parts of it out there as I do it. I can't guarantee any regularity in posting at all, or that I'll finish it. But I will do my best to finish it. I'm hoping that posting it will give me a bit of motivation.

So, this is a crossover between the Stargate universe (SG-1, SG-A and SG-U) and Star Wars. Essentially it is a couple of familiar Jedi getting involved with Earth. I think the technology lends itself to the crossover as much as anything, so...have fun with it. I have. As always, I own nothing, and I love reviews. More reviews = more motivation, so if you want to see an ending, review lots :)

What an odd place to find a Jedi Master.

Jaina waved her hand in front of the three vertically placed crystals beside the door frame and the door smoothly parted open. She peered into the dark chamber, lit only by odd display terminals, the likes of which she had never seen before.

"Jacen?"

"Over here."

Jaina followed his presence in their twin bond, as she had for the last few hours until she located his ship, more than his voice and found him hunched over sitting in front of a display terminal covered with letters in a language she did not recognize.

"Well, I'm here," Jaina said.

Here was, indeed, an odd place. It did not surprise Jaina at all that her brother, obsessed as he was with finding new ways of using the Force, would look anywhere he could for new inspirations on how to access and use the Force.

But Centerpoint Station?

If that was not enough, he found the most obscure building below the interior surface of the biosphere which seemed to be filled with the most obscure ancient computers in the galaxy.

"Mmmhmm," Jacen murmured, still intently reading the display screen.

"Why am I here?" Jaina demanded.

"I made a big discovery," Jacen said and pointed vaguely to a window on the opposite side of the room Jaina stood on, still not looking away from the computer. "Take a look over there."

Jaina crossed the room and looked through the glass.

"Kinda dark."

"Oh, right."

After soft beep behind Jaina, the lights on the other side of the glass faded in to illuminate a decent-sized room with a giant stone ring standing on a platform. She could barely make out several of the odd shapes around the middle of the ring, some of which she recognized as Corellian star constellations.

"Wow!" Jaina said sarcastically, turning back to him. "You found a big round rock!"

"Astria Porta," Jacen corrected, finally turning to face her. "I believe it translates to 'Stargate.' And I think I found out who built the Corellian sector."

"As you know, Corellia, Selonia, Talus, Tralus, and Drall were all planets from another part of the galaxy, dragged here by Centerpoint station," Jacen said. "I've figured out who did it, and why."

"Don't stop on my account," Jaina said irritably.

Jacen smiled and continued.

"They were called Lantians. About a half million years ago a fleet of their warships was caught in an unstable intergalactic wormhole during a test of a new technology and was transported not far from here. The wormhole almost destroyed the entire fleet, leaving the ships crippled. Some of their best scientists were on board and they had to figure out a way of getting back to their home world of Atlantis. Apparently they use a technology called Astria Portas to travel between points across the universe, namely that one there that they happened to have on board one of the warships, and in order to cross the distance between here and Atlantis they needed a lot of power for the porta."

"So they built Centerpoint to harness the energy of the singularity and get home."

"Yes, but somewhere along the way they figured they also needed more sources of power – namely the repulsor systems from other nearby planets that feed into the system. Why? I don't know. The power output of Centerpoint alone far exceeded their initial calculations and was able to activate the porta to connect with Atlantis."

"And you called me out of a Jedi Council meeting for this ancient piece of garbage and a history lesson?"

"I called you out of the Jedi Council meeting because that ancient piece of garbage still works, and I've contacted the people on Atlantis. They want to meet us. In their galaxy."

"Let me get this straight," Jaina said with disbelief. "You want us to go through that old rock down there to another galaxy?"

"Yeah," Jacen said with a glint of excitement in his eye. "Sounds exciting, eh?"

"How do we get back? As you said, the power requirements are huge."

Jacen grinned broadly and turned back to his computer display.

"I actually solved a problem for them, too." Jacen called up a holographic image of a device with a ball of light above three downward-pointing prongs connected with what Jaina could only assume were power conduits. "This is a technology the Lantians here were trying to develop around the time when they built Centrepoint. You see, they normally draw power from zero point space within a contained module that looks somewhat like one of these three parts on the bottom here, but they couldn't replicate the zero-point energy module without the facilities back on Atlantis."

"They harnessed zero-point energy?" Jaina demanded. "That could be nearly limitless power with no power generators. Could you imagine what one of those in an X-wing could mean?"

"Probably better than you, but the energy isn't quite as limitless as you think. At least one of those modules would have been enough to power a Death Star for a while, but they do run out eventually. Either way, the scientists who were stranded here didn't have enough of them to get enough power to go home so they had to figure something else out. One of their scientists came up with a way of drawing power from a singularity, like the tiny star at the centre of Centerpoint. His idea was to create a tiny portable singularity within this bubble up here and feed it through the same system that the zero point energy cells used. He couldn't figure out how to create a singularity within the containment bubble he created in order to keep it safe, so they ended up building it on a scale that didn't need as much containment."

"And, let me guess, you figured out the solution to his problem?" Jaina asked suspiciously.

"The Force works in mysterious ways." Jacen grinned. "I was able to finish the experiment and… We've done some test runs and they can establish a connection with us using this thing.

"Jaina, you have to see the information in this database. I mean, they have details on how they created human life in this galaxy. Projects and experiments that they were doing as a race across the universe. There are coordinates for hundreds of locations they were trying to reach, or had just recorded for future use outside our galaxy."

"What kinds of locations?"

Jacen called up a display that indicated several eight and nine constellation codes.

"As I understand it, within a given galaxy, seven symbols are required to activate the porta. If you go outside a galaxy, you need an eighth and a lot more power. Those ones all use relative referencing – if they move a porta, they can easily figure out which symbol combination will point to that new location. They also figured out a way of doing absolute referencing to a specific location using the ninth symbol that can reach just about anywhere if you have enough power."

"Like the amount a singularity puts off."

"A singularity, or even a singularity combined with five repulsors. The amount of power the entire Centerpoint system could feed into the porta is…I couldn't even begin to calculate it, Jaina, but if I'm right it can reach over half way across the universe. Now, look at these addresses. I don't understand why some are nine symbols and others are eight, but these are planets called Earth, Destiny…ummm…that one looks like Contingency, Gamble, Utopia, and this one is where we are, Centerpoint. They all appear to be important locations within the Lantian…Empire, I guess you could call it. This one here, Atlantis, is weird. It has both an eight and a nine symbol address. I couldn't get the eight to work, but the nine symbol address did."

"And you thought it would be a good idea to contact these people on the planet Atlantis in another galaxy?"

"Well, if the builders wanted to go there after coming here it must be a nice place," Jacen reasoned. "The people there aren't the same as the original Lantians. From what little they told me, they're not what they call Ancients – the original Lantians – but a second evolution of humanoids, much like how we appear to be. They're as human as us - they look like they could be from Coruscant."

"Jacen, this is huge."

"I know. Ready to go?"

"It's so beautiful," Jaina commented, running her hand gently across the surface of the event horizon of the established wormhole. The giant whoosh of energy had caught her off guard before the giant ring compiled the energy into the stable event horizon. According to Jacen, her yelp was not too dissimilar to that of a wounded mynock. She tapped the surface of the event horizon with her finger and watched in amazement as her reflection distorted in the ripples.

"Atlantis, this is Jacen Solo, please acknowledge."

"This is Doctor Rodney McKay of Atlantis," a borderline impatient voice returned from Jacen's communicator. "Go ahead, Solo."

"I'd like to take you up on that offer of a visit," Jacen said. "If you don't mind, my sister would like to come along as well."

There was silence for a couple minutes, during which Jacen and Jaina went between looking at each other and their distorted reflections in the event horizon.

"Our shield is down, you may proceed," McKay's voice returned. "We do ask that you surrender any guns at the border. We're rather like Canada over here."

Jaina looked to her brother and mouthed Canada? He replied with a shrug.

"Understood. I'll send my weapons through first."

Jacen unclipped his lightsabers from his belt and magnetically connected the pommels together before tossing them through the event horizon.

"Was that a good idea?"

Jacen closed his eyes for a moment, and then nodded.

"Yeah. I can sense they made it through safely."

He followed the lightsabers through, and Jaina sighed. She unclipped her own lightsaber, hung it on her thumb by the belt hook, and followed her brother.
