Jack and Teal'c run back for Daniel and grab his arms moments before he looses his grip, they pull him up from the hole and drag him a few feet across the ground, they get him to his feet, "Come on, we gotta get out of here." says Jack.
As they start running towards the gate to join the others, lights appear to come down from the sky and fly around and towards them like snakes twisting and spiralling through the air, large chunks of rock fall and shake the ground and a strong wind pushes them back which makes it hard for them to move forward, Jack, Teal'c and Daniel keep falling over and have to keep helping each other up.
"Where's the gate?" shouts Teal'c, as the air fills with dust and smoke.
They eventually battle their way through and join their team members at the gate, Sam is at the DHD attempting to remove the power crystal and cut off the gate power, "What's the hold up?" asks Daniel.
"Give me a minute..." says Sam.
They have to shout very loud in order to be heard over the sound of thunder, cracking surface, the howling wind and falling boulders around them, its like Armageddon.
"Now would be a good time." says Jack.
"Got it!" says Sam, yanking out the large red power crystal from inside the DHD, the gate then almost immediately shuts down.
Conditions start to get worse and the ground shakes ever more violently, causing the team to lose their balance and stumble around, Sam starts to stumble backwards as she tries to slide the crystal back in to the DHD, Mitchell struggles over to her, "We gotta go Sam." he says, he and Sam both hold the crystal and pull themselves towards the DHD and slide it inside.
The crystal is successfully inserted and they get the dial cover back in place and it powers back up, because they and the DHD are shaking so much its hard to see and push the symbols, but they manage it and slam their fists down on the activation button, the gate then activates.
Jack gets on his radio, "SG-1 coming through." he shouts, "...Go!" he says.
A part of the ground suddenly breaks beneath the gate and rises a few feet in to the air and knocks the gate over, tipping it backwards, they watch in horror as it crashes to the ground, but its still active so they make a run for it, helping each other keep their balance they all go for the gate and leap through the air, jumping in to the event horizon.
At Stargate Command they've all been running around frantically trying to turn off the gate at their end so that SG-1 could dial in, turning off the bases power did nothing and they even resorted to severing the power cables completely but again that fails, the gate eventually just shuts down by itself, occurring simultaneously at the precise moment Sam removed the crystal from the DHD on P3X-474.
"The gate is off line Sir." says Walter.
When the gate at the SGC shut down they decided to give it a few minutes in the hope that SG-1 would now be able dial in, but several minutes later and the gate is still showing no activity, Landry stares at the gate with desperation.
"They should have dialled in by now...dial it back." he orders.
Walter dials P3X-474, but as the seventh chevron spins around, it fails to activate.
"Chevron seven..will not lock." says Walter.
"Try it again." orders Landry.
They try again but the same thing happens, no lock or connection is made.
"It won't lock, General" says Walter.
"Why not?" asks an anxious Landry.
"I'm not sure Sir, I'll run a full diagnostic, but when we can't make a lock it usually means the gate is buried...or it isn't their anymore." replies Walter with worry.
Landry stares back at the inactive gate for a moment then turns back to Walter, "Contact the Daedalus, tell them to divert to P3X-474 and find out what's going on, I want to know the moment they know anything." he says, then heads away towards his office.
"Yes Sir." replies Walter.
The Daedalus was on its way to the Pegasus galaxy to help clean up the mess and recover hive ships that have been left drifting in space after the Wraith simply vanished in to thin air a little over a month ago, they were on the very edge of the Milky Way when they picked up the transmission from Stargate Command, ordering them to change course.
A few minutes later and the Daedalus would have been out of range so its lucky they picked up the transmission at all, Colonel Caldwell acknowledged the transmission and turned the ship around, it took them almost 4 hours but they eventually reached P3X-474.
When the ship exited hyperspace, Caldwell immediately sprung from his chair and took a few steps towards the window on the bridge.
"What in God's name is that." he says out loud, standing in disbelief at what he sees in front of them.
Directly in front of them where P3X-474 should be, the planet appears to have turned in to something else entirely, they see a massive circular cloud, it looks like a plasma cloud, black and grey and parts of it are constantly illuminated by flashes or orange light from inside it.
Caldwell turns to his first officer, "Major Marks, anything?" he says.
"Erm, the sensors are having a hard time detecting anything Sir, I'm getting a massive energy reading but can't determine what it is...I think its overloading the sensors." replies Marks.
"Life signs?" asks Caldwell.
Marks pushes a few buttons and shakes his head with a shoulder shrug, "No idea Sir...there's nothing..I...I...not getting anything." he says.
Caldwell walks back and sits his chair, "Contact Stargate Command, let them know what we've found."
Jack slowly opens his eyes, his vision is blurred and his head hurts like he's waking up after being knocked out cold, laying on the ground he moves his arms placing his hands on the ground to push himself up in to a kneeling position, he rubs his eyes as his vision becomes clearer, looking around he immediately sees Daniel laying on the ground a few feet away so he crawls towards him.
Jack places his hand on Daniel's shoulder and shakes him, "Daniel" he says, "Daniel" he shouts.
Daniel wakes up sharply and then turns around, "Jack?!" he says.
"Yeah its me. You alright?" says Jack.
"I think so." replies Daniel, he looks around briefly, "Where are we?" he asks.
"You tell me." says Jack.
They hear a moan and look over to see Teal'c and Mitchell getting to their feet, "T." shouts Jack, he and Daniel get up and walk over to them, Sam and Vala are on the ground near Teal'c so they wake and help them up, apart from them all suffering from some sort of concussion, they're relatively in good shape.
They stand and look at their surroundings, they appear to be standing in a large open area within some very old ruins, there isn't much to be seen, apart from the ground the only structures around them are broken columns and slabs of stone that randomly stand in the distance around them, behind them is a circle that looks like a Stargate, but it doesn't have chevrons and instead of star constellations it is engraved with the same type of text Daniel found on the large stone on P3X-474.
Amazingly the sky is crystal clear, but instead of clouds they see space, they see planets, stars and beautiful particle clouds of purple, yellow and greens, they appear to be right up close to everything, its as if they could reach out and touch them.
Worryingly they don't see anything beyond the ruins which are just a few hundred meters across and wide, no trees or mountains or even a surface, its as if the ruins are just floating in space.
"Okay, I'm going to go out on a limb here and say this isn't the SGC." says Jack.
"We definitely dialled Earth, right?" asks Mitchell.
"Yeah...it was a little shaky back there but it was definitely the correct address." replies Sam.
"Then how did we end up here?...wherever here is." asks Mitchell.
Sam turns around and looks at the strange Stargate, "Well we obviously came through the gate...if that is a gate. We've seen wormholes jump to other gates before, if there was an explosion when we went through the gate on P3X-474 then the resulting blast could have cause the wormhole to jump and send us here." she says.
"Yeah okay, lets just dial this thing up and go home." says Jack.
"That's a great idea, there's just one tiny problem." says Vala.
"What?" asks Jack.
"Look around...do you see a dialling device anywhere?" says Vala.
