A/n: Bit more of stargate coming in this chapter. I"ve tried to explain everything though. Don't forget to review ;)

"Well, Sparx, it certainly looks like they're hiding something down there," commented Ace. Below them was the entrance to Cheyenne Mountain Complex, presumably the SGC – Stargate Command. Of course they weren't exactly going to write that on the door.

"So let's go and see if they'll help us."

"Hold on, they're not just going to let us in. I doubt any of the guards up here even know what's down there. I think we need to get inside before we'll find anyone who can help us."

"Well we're going to have to blast in, Ace. Their security's pretty good."

"I don't think they'll like that."

"I know! But from what I've seen everything's heavily guarded. We can't sneak in anywhere."

"What about how they get their electricity down there. Do you know if they've got that protected?"

"I don't know. Everything else is guarded. Why would they be so stupid as to leave that open?"

"Because," said Ace. "I don't think anyone in this world can move through an electrical wire."

"Hey, you're right. It's worth a try!"

Ace and Sparx flew down behind a big army truck.

"There's a power outlet over there," said Sparx, pointing to a camera on the wall. "But the guy on guard's too close. He'll see us. Think we should knock him out?"

"No," sighed Ace, "I've got a better idea. Close your eyes."

Sparx shrugged and shut them. Ace shut his own and then fired a bolt of lightning into the sky, straight past the guard's face. When they looked up he was stumbling around, trying to clear his eyes from the sudden bright light.

"C'mon, Sparx," Ace whispered.

They walked up to the camera, and turning into pure electricity, disappeared into the wire.

"C'mon, Carter. I can't go fishing by myself!" complained Colonel Jack O'Neill.

The Major smiled and quickened her pace through the corridors or the SGC. "Why not? You always seem to." Jack was constantly trying to get the SG-1 team to go fishing with him. All of them knew that this was not a good idea and Sam wasn't going to get herself dragged in. "Besides, sir, I've got work to do."

"Alright, now that is a lie," said Jack. "We've got a week off. You're not supposed to be working." SG-1 spent most of their time travelling through the stargate to explore new planets millions of light years away, sometimes fighting the Gould and even saving the world a few times. And yet when they got time off and Jack asked them to come fishing with him they all seemed to have something to do. You'd think they'd appreciate a nice, relaxing fishing holiday, thought Jack.

Suddenly the overhead lights flickered. They flared brightly for a half-second, then dimmed back to normal, a few dying completely. It seemed to sweep up the corridor in a wave and then it was gone.

"Sir, did you just see that?" Carter asked, halting.

"Yeah, it's probably a power surge or something… right?"

"I don't think so…" she replied, looking puzzled.

The sound of a siren interrupted them. "Intruders in the control room," came Simmons' voice over the loudspeakers.

Sam and Jack exchanged glances and then ran off down the corridor.

So much for fishing, though Jack.

In a flash of light Sparx and Ace materialised into the control room. Through the glass windows they could see a large ring with a ramp leading up to it – the stargate. It was a dark grey-blue colour with symbols scattered around its circumference.

"Told you I was right," said Sparx triumphantly.

There was a guy sitting at one of the computers. He looked rather shocked.

"Hi there," said Ace, "Sorry to barge in."

Simmons just stared for another second, then took off his glasses, cleaned them, put them back on and stared again. "How'd you get in here?" he finally asked.

Ace started to explain but Simmons seemed to remember what he was supposed to do. "Alright just stay over there and put your hands up." He pulled out his sidearm and waved it at them.

Ace recognised that it must be a weapon and obeyed. Sparx reluctantly followed Ace's example.

"We just need to borrow your 'gate," Ace explained.

Simmons ignored them and set off an alarm. "Intruders in the control room," he said into a microphone.

Ace shrugged as some men with larger guns ran in. "I suppose that works too…"

The General walked in along with Colonel O'Neill and Major Carter.

"What's going on?" General Hammond demanded. He saw Ace and Sparx. "How'd you get in? The 'gate hasn't been active for hours."

Ace went to explain but Simmons interrupted. "They just appeared out of that computer, sir."

"Actually," said Ace, getting slightly annoyed at the technician, "we came down through your power cables from the surface."

"So you didn't come through the stargate?" asked Sam.

"No, we didn't, but we need to use it now."

"You could've just asked," said Jack.

"We were about to. We figured you'd pay more attention if we got down here first."

"Yeah, well you got that right."

"Alright, lower your weapons," said the General. He turned to Ace. "I'm General Hammond, I command this base."

Ace introduced himself and Sparx, and the General introduced Sam and Jack.

"I can't just let you use the gate," the General explained. "Perhaps we can go somewhere else and talk."

"Alright then," said Ace.

"Talk!" cut in Sparx. "Ace, what about Mark!"

"We've got to get to the sixth dimension first, Sparx and we need their help."

"Sixth dimension?" questioned the Major.

"Alright, let's get to the briefing room first," said General Hammond.

Fifteen minutes later Daniel, SG-1's anthropologist/archaeologist/linguist, and Teal'c, a Jaffa who'd teamed up with them to help fight the Gould, had joined the rest of SG-1, General Hammond and the lightning knights in the briefing room.

Ace was explaining how they'd gotten to Earth and about their mission to stop Lord Fear before he took over every known dimension. The Colonel couldn't help thinking it sounded a bit like a video game he'd played once.

Everyone was listening fairly attentively. Daniel noticed that Sam's eyes kept straying to the thing Sparx had called the lightning flash, probably wondering how it worked. It had floated in after them and parked itself up in a corner. Sparx had told them it was safe, unless it malfunctioned and fell down. No one had sat in the seat nearest to it.

"So what do you need to use the stargate for?" Jack was asking. "Can't you just use you're amulet thing or whatever?"

"We'd need at least two pieces," said Ace.

"Bummer," said Jack.

"Lord Fear has the rest. We only got this piece because Mark dropped it when Lord Fear kidnapped him."

"So you need the stargate so you can rescue your friend, right?" Daniel put in.

"That's right."

"I don't think the stargate can take you to another dimension though," said Carter. "At least we've never got it to."

"The Gould have never been able to accomplish this either," said Teal'c.

"Gould?" asked Ace.

"Yeah, they're snakes. They crawl into your head and take over your mind," Jack explained.

"Parasites," corrected Sam. "They use humans as a host."

"I'm sure I've heard that name somewhere…" said Ace. "Probably from Sparx always watching that show. Anyway, I know you can use the stargate to get to the sixth dimension. We have one there."

Daniel thought for a second. "What's the address to get there then?" For the stargate to work a certain number of the symbols had to be dialled in order to give the address of the target 'gate.

"Give me a piece of paper." Ace scribbled on the paper for a few seconds then handed it back.

Daniel wasn't entirely surprised to see it consisted of nine symbols.

"Of course, the ninth chevron!" exclaimed Sam snatching the paper off Daniel.

"We usually only use seven…" said the General.

"If we use eight we get another galaxy," explained Daniel. "So nine must give us another universe or dimension."

"Well we need to leave soon," said Ace. "Mark's been there for a few hours. And it wont take Fear long to get his plans moving."

"Sir, I think we should go with them," said Jack. He turned to Ace and Sparx. "If that's okay with you guys?"

"We need all the help we can get," said Ace.

"When do you need to leave?" asked the General.

"As soon as possible. Within one of your Earth hours I suppose."

"Colonel, I don't know if we can collect enough information in that time. You know we'll need more time than that to scout out something like this."

"General," cut in Daniel, "this is an entire new dimension. Think what new civilizations we'd find. This isn't just one new planet, it's a whole universe."

"New weapons, sir," put in Jack. "Would you let us have some in exchange for helping you?" he asked Ace.

Ace shrugged. "Whatever."

"See we should help them."

"I can't put SG-1 at risk for something that has nothing to do with this planet…"

"Lord Fear is going to bring an army back if we don't stop him," said Ace. "This has everything to do with your planet."

"And what about Mark!" cut in Sparx. Ace had told her to let him talk but she was getting annoyed at everyone going on about everything but Mark. She stood up angrily. "We need to go rescue him now! He may be able to fight okay in his own world but Lord Fear could destroy him in the sixth dimension!"

"Then he is not from your world?" questioned Teal'c.

"No! He's from here. He's just a kid anyway."

"What?!" shouted Jack standing up abruptly. "A kid's been helping you? A human kid? What'd you let him go and get himself kidnapped for?"

"Colonel…" warned Hammond.

"Sir!" O'Neill shot back.

"Colonel…"

"General, they need our help and so does that kid. You can't let…"

"Jack! Get your team ready. You're leaving in a half hour."
