Sheppard, McKay, Ronan and Teyla are on board a Jumper heading for the planet.
"Why did I have to come?" moans McKay "Because" replies Sheppard "Because why?" says McKay "Just because" says Sheppard "I have better things to do you know" says McKay "Like what?" asks Sheppard "Well let me see...errm...getting the Atlantis flight controls back online for one!" shouts McKay "Stop complaining" replies Sheppard.
They're almost at the planet and a scan of the planet appears on the Jumpers HUD and a flashing light indicating something is on the surface "Huh I guess there is something down there" says McKay "What is it?" asks Teyla "Let's go take a look" replies Sheppard.
They descend through the atmosphere and head towards the indicated marker on the HUD and as they get closer they see a large stone structure "Right there look there it is" says McKay "I see it Rodney" replies Sheppard as he maneuvers the Jumper and lands in front of the structure.
They open the back of the Jumper and pick up their weapons checking they're loaded and then head outside.
Standing at the face of the structure at what appears to be a large closed doorway "I recognize these writings" says Teyla "What does it say?" asks Ronan "I do not know" says Teyla "I thought you said you recognized it" blurts McKay "I do not know what it says but it is the same writing as that in the city of the ancestors on Athos. There are other writings here I do not recognize." says Teyla.
"OK McKay get to work" says Sheppard "Right. Give me a minute" says McKay as he gets to work trying to figure out how to gain access to the structure.
McKay has a look around the doorway and steps back to the others "Huh." says McKay "What?" asks Sheppard "I can't open it" says McKay "McKay" says Sheppard "What? I know you all think I'm a genius and you're right I am but do you see a handle or a switch anywhere around here!. There's no energy signatures or anything, I don't have a clue how to open this." says McKay in an irritating manner.
"C4?" says Sheppard "Wait, wait, wait, wait" shouts McKay as he starts feeling around the door "What are you doing, McKay" asks Sheppard "I remember something from Daniel Jackson, when he was on a mission with a Russian team they came across an old stone door and he opened it by pushing symbols in sequence" replies McKay.
McKay spends a few minutes feeling around and manages to locate 5 protruding symbols "OK looks like a 5 symbol combination" says McKay "Good work Rodney, what's the combination?" asks Sheppard as they all turn and look at one another and after a moment of silence "Well I guess we start entering random combinations and hope we get lucky" says McKay "Good idea" replies Sheppard.
Back on Gaia, O'Neill and his team are stunned at the state of the Nox city "OK everyone fan out and keep your eyes open for the Nox or..whoever" says O'Neill and they all head off in to the woods.
The woods are eerily silent "This is creepy" says Carter "Yeah, keep your eyes open" replies O'Neill "This doesn't make any sense" says Daniel as he stops and sits on a tree stump "Daniel" says Carter and they hear a branch crack behind them and turn to face it with weapons pointed "What was that?" asks Daniel "Get back" orders O'Neill so Daniel and Carter move behind a tree "See anything?" asks Carter "Nothing" replies O'Neill.
Moments later they hear gunfire and O'Neill gets on his radio "Dawson report" he says quietly "We've engaged hostiles, Sir" shouts Col Dawson down the radio "Let's go!" shouts O'Neill as they head to Dawson's location.
They arrive to see the other team under heavy fire from a single black figure using some type of laser weapon and they join the fight and begin firing, their bullets appear to do no damage at all as the figure continues moving towards them.
Lt James runs out of ammunition and pulls his knife from his belt and rushes toward the figure but the figure swings his arm and launches Lt James into the air and against some trees like he was a rag doll.
Carter and Henley circle around to check on Lt James "Henley?" shouts O'Neill "He's badly injured Sir" shouts Henley "Fall back" shouts O'Neill and they all move backwards still firing at the figure and Carter and Henley pull Lt James out of the way.
With everyone now moved back, O'Neill steps forward and pulls out a grenade and throws it just ahead of the figure "DOWN!" he shouts as the grenade explodes and they all hit the ground covering their heads, they lift their heads to look behind them and see the figure unaffected and still coming "It didn't work" says Dawson "Fall back to the gate" says O'Neill and they all rush back to the gate with Dawson carrying Lt James on his shoulder.
Daniel is the first back at the gate and begins dialing Earth but stops part way through "Sam" says Daniel "What?" says Carter as Daniel points to a black device latched to the gate. "What are you waiting for, dial it up" says O'Neill rushing up behind them "Sir there's a device on the gate" says Carter and O'Neill looks at it "Just dial it up" he says.
The gate activates and Daniel sends the ID "Good to go" he shouts as he runs through the gate with everyone following behind "Go, Go" says O'Neill as Dawson runs passed him with Lt James on his shoulders while O'Neill lays down cover fire at the figure that is still moving towards them. O'Neill gets to his feet and runs towards the gate but just as he reaches it the black device emits a red glow and the gate shuts off.
O'Neill looks bewildered and turns around to see the black figure still approaching so raises his weapon to fire but he's out of ammo "God" he says and throws his P90 to the floor and takes out his hand gun, drops to one knee and empties the chamber toward the figure then looks down at his gun when the ammo runs out and looks back up at the figure with a worried look on his face.
The figure stands still and raises his laser weapon pointed at O'Neill "Who are you. What are you." shouts O'Neill. Then suddenly he hears large weapons fire that directly hits the figure in black and blasting a big hole in the ground and O'Neill looks to the sky and sees an Al'Kesh hovering above and voice comes over the radio "Are you ok O'Neill" it says and O'Neill reaches over to his radio "Teal'c?" he asks "It is I O'Neill. Do you require assistance" says Teal'c "Sure. Great timing by the way." replies O'Neill.
"SGC this is Teal'c, O'Neill is fine." Teal'c radios in to Earth and everyone is relieved.
"Move away from the gate and I will ring you aboard O'Neill" says Teal'c "Right" replies O'Neill as he stands up and walks over to the hole in the ground and looks in..he sees pieces of black armuor scattered around but no blood or body in sight.
O'Neill is ringed on board the Al'Kesh and puts his hand on Teal'cs shoulder "Good to see you buddy" says O'Neill "And you" replies Teal'c "What are you doing here anyway?" asks O'Neill "I heard about Lya and thought you may require my assistance" replies Teal'c "I'm glad you came" says O'Neill "As am I" says Teal'c", "Let's go home" says O'Neill and the Al'Kesh flies off headed for Earth.
Back in Pegasus
McKay has been entering random sequences using the 5 symbols on the stone doorway for some time and he finally gets the correct combination and the doorway opens with dust flying from beneath it and a strong gust of wind as the corridor fills with air.
"OK who wants to go down the creepy corridor first?" says McKay and Ronan pulls out his gun and walks through the doorway cautiously with the others following and they continue walking down a very long dark corridor "Do you hear that?" asks Teyla "Hear what I don't hear anything" says McKay and Sheppard looks up "LOOK OUT" he shouts and hugs the wall just as a piece of the ceiling falls to the floor.
"That was close" he says "Maybe we should err go back to the Jumper" says McKay "It looks solid enough for now" says Ronan "Let's keep going" says Sheppard and they continue walking slowly.
Eventually they come to the entrance to a large room "Sheppard" says Ronan and they both stand at either side of the entrance, Sheppard turns and signals to McKay and Teyla to wait here and then he and Ronan slowly step in to and sweep the room. "John" whispers Teyla "It's clear" replies Sheppard "There's no other doors in here" says Ronan as he walks back to the group.
"We went through all of that for an empty room, are you serious" moans McKay then at the back of the room a light illuminates a part of the wall and Sheppard walks over to it and sees something, he calls McKay over "What, what is it?" he asks as he walks over to the wall "A crystal" says McKay as he picks it up "So not an empty room" says Sheppard "Guess not" says McKay.
"They built all this for that" asks Ronan "What is it for?" asks Teyla "I don't know yet" replies McKay while examining the crystal.
Just then they hear a rumbling sound and parts of the ceiling collapse "Time to go" shouts Sheppard "Wait there may be more in here" shouts McKay "No time Rodney" says Sheppard as he grabs McKay and pulls him out of the room.
They run through the dark corridor with the structure collapsing behind them "Move, move" shouts Sheppard and they just make it out by jumping through the doorway a split second before it fully collapses.
"Is everyone alright" asks Teyla "I'm good" says Ronan "McKay?" says Sheppard "Yeah yeah I'm fine" says McKay "Let's get back to Atlantis" says Sheppard and so they get to their feet and head for the Jumper.
