A/N: What Sian truly is will be explained during the next three chapters, by chapter four a good history of what she, Thief and Snatcher truly are well be told.

Atlantis 2009
Earth: San Fransico Bay

Rodney paced in Woosley's office, six months ago had seen the arivial and departure of a woman from the future, and new technology that only the Ancients could have dreamed up. And the bad thing about it was mostly that Rodney hated what was going on anyhow. Not that it mattered if he hated anything going on. The womans arrival, and her sudden leaving left much to be desired. Now Rodney was trying to stay as sane as he could to figure out what was going on. Already the Air Force had started a group called the Cyberdeck Research Core. And their current best program which Rodney had helped write the basecode for, was called Skynet. And already several networks around the globe were affefcted by cyber attacks, well everywhere but Atlantis. Nothing got past their shields, not even internet virii.

"Tell me again what is going on Rodney." Woosley said with caution in his voice. He too did not liek the way things were going. None of them did.

"Well, If the reports are right which i'm sure they are, something is attacking and either knocking out or totally rewriting the data of several networks, mostly cellphone and radio networks, two way radios are useless, as well as cellphones, currently only a tracphone would do you only so much until you need a landline" Rodney said.

"And that's bad how?" John asked from where he said in the easy chair in the office, Rodney had called the team to the office before breakfast, and even then John was cranky. No Coke before breakie, equals bad and everyone knew it when around John.

"Well, if my thoughts are right then Sian was telling the truth about Skynet, and I helped design the basecode for it. Only thing was that when it was uploaded into a airforce computer two weeks ago did the reports of power and networks dying start." Rodney said, If that was right, and Rodney designed the very basic basecode for the system, only it went self aware.

"Is there a way we can tell Sian?" Teyla asked. Sian did say that after meeting with the Atlantis team and going back home the war against the machines was won. Mostly. the Earth was toasted, so they had to find a new home, and Skynet had taken the location of the SGC as its homebase.

"Its been six months since we met Sian, I doubt we can send a notice from the past to the future, the time dilation field doesn't work that way." Rodney said, he himself barely understood how it worked, but then Sian had told him what to do and how to get her back home in one piece.

"Worth a try anyhow. Rodney, look, six months ago Sian said that Skynet went live on October tenth ten am eastern of this year, that's tomorrow morning. Now I'll let myself get shot before anything happens to this city" John said. He meant it too.

"Right yeah, but there's only one problem. Even though I wrote the basic basecode for Skynet, it evolved to the point wherein trying to rewrite anything would make it aggressive" Rodney said, they all remembered what happened with the replicators two years before.

"Yeah there is that little problem too so that idea is out then I take it?" John said, Rodney nodded, yep that plan was out. "Is the shield up." He got another nod, that was good, the city was both shielded and cloaked. perfect.

"Now what?"

"We wait for tomorrow"

"What? We wait? don't we want to try and shut this thing down? Nothing works out there we can't even contact the Daedalus for gods sakes Colonel" Rodney said sounding as if he was going to blow a bloodvessel.

"Yeah, I noticed that. you think it is Skynet."

"No shit sherlock!" Rodney retored.

"Gentlemen calm down, all we know is what Sian told us six months ago to be ready for the tenth, Rodney, you made the basecode, how long ago was that?" Richard asked.

"When the SGC was having that trouble with Anubis, Sam asked me to write a bascode to help disengage the stargate, it didn't work, then I redid a few parts during the Replicator battle for the Asgard." Rodney said

"So it was a few years ago that Skynet was actually created?"

"It looks like it"

"OK, Gentlemen and Ladies, you have six hours to disengage every airforce computer. McKay, I want you to make a totally new version of Skynet, only in this case, to act like a replicator virus during the shutting down fo the stargate network." Richard said.

"Six hours? I can't do that in six hours, for all i know if we try to shut down any air force machines it might start the thing off, you saw what the data contained that Sians friends sent to us when seeking help and warning of incoming invasion" Rodney said sounding scared out of his mind.

"Just do it" Richard said. Rodney couldn't argue with that now could he?

October 10; 2028; 0208 am
Skynet factory; Ruins of Shanghai

This has to work, this just has to. Sian thought, the last six months had been hell, Rodney had sent the T-182 to its death, Sweetheart also sfaely returned with her, but something else had been done to Sian herself. Anything machinery unless made for her to use, broke when she touched it, or refused to work. Then other things started happening. First she thought them just dreams, but they ended up being worse. She didn't blame Rodney McKay, he was trying to help, and he got them both home. She blamed Skynet, they had nabbed her again leaving Sweetheart on his own.

She never expected it, but after waking up inside a odd room, not an experimentation room, but a glass room, she had freaked out, what happened? What was going on? Then the gas happened, she passed out. Hours later she woke up, out on the streets somewhere, Thief stood over her prone form, worried no doubt, "What happened?" She asked slowly getting to her feet with Thiefs help. Thief looked white as a sheet. "What is it?"

Instead of answering right away Thief just stared at her friend for a full minute, which made Sian worried, "Thief?" She snapped her fingers, "snap out of it, what's wrong? You look sick." Sian had no idea what had happened when the gas knocked her out, how long ago was that? Then she felt it, a draft on her back. She passed it off as something normal, that is, until something touched her between the shoulderblades. Sian turned around, "Snatcher?" Nobody was there, the touch came again, was Thief playing jokes? Apparently not because she held her frimly..... by what? "What is that?" Sian asked seeing it as she turned back, it seemed to come from behind her.

It was a odd, mothlike wing, torn in many places, and burned as well, the pattern of the faberic like thing matched Sians clothing, black and red. And injured. Thief gave a fake smile and said simply "Well.... its hooked to you, you have four of these... .things...." She said trying to sound upbeat when she was in fact scared out of her mind. "let me try something" Thief said and gave a yank on the .... thing...

Instant pain shot through Sian nearly sending her to her knees. With a strangled cry she said to Thief "Don't.... do that.... again!" She leaned against a building, or rather, what was left of one. sunrise was coming on and things got brighter, allowing Sian to see what exactly Thief had pulled on in a broken window. Her eyes opened wide, she stared at her reflection. Staring back at her was a woman, with gossomar wings of the blackest black and reddest red. Did Skynet do it? She had to be dreaming.

Thief just stood there, "You look....... different" She said.

"How differnet?" Sian asked, her overall body and face hadn't changed, other then the wings.

"Well... you have wings." Thief said not missing a beat, if there was a laugh track Sian could surly hear it going off right then and there.

"No, really? whatever tipped you off?" Sian asked all of a sudden horrified of what the team would try to do to her. "What about the others?" she watched her reflection, thinking of folding down the wings, which they did, folding flat to her back. Now she looked, normal as anyone with wings folded against their back would look.

"Uhm, about them." Thief said.

"What about about the team?" Sian asked staring at herself in the broken window. "What happened while I was gone? How long was I gone?"

"Well, you went through the datafield, a T-182 shortly followed, about a day after you left, two days later Snatcher and I sent Sweetheart after you. Then a week later we came across Sweetheart in a lone ranger type battle. Never found you until now. Most of the team is gone. Dead. Terminators got to them, there's a MH and several HKs that have pretty much made Shanghai their bathroom." Thief said sitting on the hood of a blasted car, her brown hair framing a elflike face.

Sian turned around, "When did you guys find Sweetheart?" She asked, she looked like hell and she knew it, but felt.... great.

"About a month ago." Came the answer.

Sian went slackjawed, she'd been gassed for that long? Then she noticed how starving she was. Thief must have thought ahead and handed her something, a stimcell bar. Which seemed to help. "I was gone a month?" She asked.

"Apparently so, some crewmen reported seeing something with large wings, they reported it as a giant moth, nothing more, the nuclear radiation of the bombs must have messed with the natural order of things I think. But apparently it is not so." Thief said, "I went looking for this giant moth and found you instead."

"Oh so that's it? I'm a giant moth? Where's Snatcher?"

"Missing"

"For how long?"

"A day... maybe more"

"Have a radio?"

"Yup" The radio was passed over. only to have it die in Sians hands.

"OK, this isn't good." She said handing the radio back to Thief, it powered right up. "Call the team together, those that are still alive, tell them you found me..... mostly. And tell them to meet up at the harbor. And not to panic, I'm going to try something." Six months later her trying became more then just trying, it became a will to survive, more and more foods she used to love to eat she could not even go near, much less smell. Now she had just barely convinced her comrades to let her do this mission alone, the less people who could be detected the better, that and she was getting the hang of flying for once as well.

Standing at a air vent leading out of the Shanghai factory Sian took a deep breath and tried ot remember why exactly she was there. I hope this works. She thought before flipping open the vent and dropping into the factory. It was her only chance she had, years ago she had met with the people from Atlantis, and had been helped by them, now she had to try and get back there, to warn them of what was about to happen with Skynet. It had made a mobile base, and it was headed for the famed Old City in the sky.
