Okay, this is the most disturbing, sick, twisted, and demented story I have ever written - and that's saying something! The worst part of this was the fact that this story comes from a nightmare I just had. o.O I don't know why I dreamed this and frankly it's slightly disturbing that I did at all! I dreamed the entire prologue, and I just decided to go from there.

This is a Stargate: Atlantis crossover - with what, you'll probably figure out in the prologue, but if you don't oh well. It is my first attempt at a fanfiction in either shows.

I don't expect it to be very long, however as a full time college student and working part time, there will be long periods of time where I won't be able to update. So don't get mad!

Please review! I'd love to hear comments and feedback. Pretty please????

Disclaimer: I don't own ANYthing in this story except for the plot. So don't steal the only thing I'll ever be able to own...

Dark Requiem

Prologue

It was dark and dank. The walls were covered in slime slowly dripping down the dark twisted walls. Ridges of what looked like coils stuck out of the wall, dipping and protruding, creating a deformed illusion.

The ground was also covered in the slim, hindering anything that walked on top of it. The ground was tilted slightly and was uneven, bumps and dirt dragged in from the outside littered the ground along with dark stains.

Lights flickered occasionally in the distance and inhuman shrieks could be heard resonating throughout the corridors. The overwhelming stench of decay and rot filled all the rooms but the carcasses were no where to be seen.

It felt completely alien.

To John, that wasn't something new. He had been to many different planets and places, but none had given him such a chill of horror and fear as this place had. There was just something so alien about it.

In his crouched position against the wall, he could see everything in front of him. His P-90 was fastened to him, held ready for anyone or anything. He knew there was something lurking in the darkness.

Something had killed the expedition.

There was another shriek from down the hall and he shuddered involuntarily. He was supposed to be on vacation right now, just relaxing in Atlantis. Why, he thought, why had he chosen to take this mission.

It was just supposed to be in and out. When first expedition of scientists failed to report in, Atlantis sent in a team to figure out what was wrong. When that team didn't return, his team was sent to recover them.

It appeared that they wouldn't be returning either.

There was a crackle in his earpiece returning him from his thoughts. Mckay was ranting to himself all the while cursing his laptop, the heavens, even John - Anything that came to his mind.

He had left his friend in the only secure area he could find. It was a barren room with only one way in. In normal circumstances he would have left Mckay in a room with at least two exits, but not today. One door meant only one way for the creatures to come - only one way to fight.

Mckay had created a make-shift camera to attach to Johns' gun so he could monitor what was happening with his laptop from afar. That way Mckay could see and warn him before something happened from a safe distance.

Safe. He bit his lip hard. He didn't know where Teyla and Ronon were and he couldn't contact them. All he had found so far was a bloody ear piece; nothing else. It was probably too much to hope for that they were still alive, but by God he wasn't going to leave them without finding out.

There was static, interrupting him from his thoughts before a strained voice came in. "I-I think I got the schematic of the building. You see that hole several yards away?"

John's eyes narrowed and quickly found the gaping hole. "Yeah," he whispered.

"You need to go down there."

"Are you sure?"

There was silence. "Of course I'm sure! I'm not just sitting here for the show. As much as I'd like to watch you make a fool of yourself we need to get the power on."

"Yeah, yeah," John whispered, making a quick glance around before moving stealthily towards the hole. "Don't get your panties in a twist."

Ignoring the sputtering coming from the other side, he maneuvered himself once again against the wall. "Tell me if you see anything." He turned the light on the gun back on and lowered it down the hole.

Slowly, he started to rotate it around. Then once more for extra measure.

"I don't see anything," came the hushed reply. "It looks like there's a lot of boxes down there, so they could be hiding."

"Damn," he growled. He peered down himself. "I'm going in anyway."

"Make sure to be quiet!"

"Yes mother," he quiped back. He grabbed the edge of the hole, making sure he had a steady grip, and slowly lowered himeslf down. His gun swung slightly, as he let go of it, allowing the strap to fall onto his shoulder.

The light from his gun swung to and fro illuminating patches of the dark ground.

With a deep breath, he let go and dropped to the ground. He immediately went into a crouch, grabbing his gun out in front of him, ready for any attack.

There was none.

Sweat dripped from his head and he resisted the urge to whip it. Slowly getting into a standing position, he looked around using the gun as a light.

"There!" shouted a voice in his ear. "Go back! Back! Back! Back!"

He slowly trailed his gun back until the voice commanded him to stop. "There! It's right there. Do you see it?"

Several yards in front of John was a large wall that had wires coming in and out of it. There was a black metal box hidden between the bigger wires that climbed the walls and hooked into power supplies.

With a chill, he noticed that the big wires were sliced open.

Taking one last glance around, he slowly walked over to the box. He yanked at the door, but it wouldn't open. Tucking his gun underneath his armpit, so that the camera was looking behind him, he grabbed a Swiss knife from his pocket and flipped out the knife.

The door was opened quickly and efficiently. It was a mess in there with wires of every shape and color jutting everywhere.

Glancing around again just to make sure it was clear, he grabbed the gun and pointed the camera at the wires. "Tell me what to do," he hissed.

There was a moment of silence from the other side. "Hang on - just - wait - got it!" The directions came fast and swiftly, Mckay only having to correct him a couple of times on several errors ("The blue! The blue! That's not blue! Are you colorblind?!" "It was blue!" "Seafoam!" "You're horrible at giving directions." "Well deal with it!" "Is it too late to order another genius?" "Sorry, they're all on hold at the moment, you're just going to be stuck with me. The blue Sheppard!" "I got it!").

"Now push the lever up."

"Roger that." Closing his eyes and taking a deep breath, he grabbed the lever and pulled it up. For a couple of seconds nothing happened and Johns' stomach sank. All this and it hadn't worked. What were they going to do now?

But the lights flickered and then turned on, illuminating the darkness of the corridors and rooms. The power was back on.

Grinning, Sheppard leaned his head against the box. "We did it Mckay. Now," he was cut off by a scream in his ear.

"JOHN! Behind you!"

Unconsciously he had allowed his gun to drop and dangle from his shoulder once again. The swinging gun had a perfect visual of what lurked behind him.

Swallowing the knot in his throat, he slowly reached down and grabbed his gun to face his adversary.

------------------------------------------

Rodney could hear screaming and shouting on the other side of the radio. His hands shook, laying still just above the keyboard. The camera had gone out just as John had turned around. All he knew was that he couldn't see anything and that John was screaming.

"John?" he choked. "Are you still there? John? Oh God." He moaned, bringing his shaky hands up to his wan face. John was dying and he couldn't do anything about it.

Letting a soft sob through, he looked back at the computer. It hadn't done them much good this entire time, even with the portable camera. Maybe he could get the schematics going with the life sign detector. Maybe John was still alive?

There was an ominous creak from the ceiling making Rodney freeze. Wasn't there air ducts up there? He slowly lifted his head to look up, but nothing came crashing down on top of him. There was another creak.

He picked up the life sign detector, but dropped several seconds later, his shaking hands unable to hold it. For there, only several feet away showed another life sign.

"Oh God, oh God, oh God," he chanted, scooping up his laptop and life sign detector. He had to get out of here. His P-90 was gone but he still had a hand gun. Checking to make sure he still had a couple rounds left, he slowly backed out of the room.

And bumped into something, dropping his gun in the process.

Letting out a surprised shriek, he whirled around to come face to face with Dr. Galeia. His eyes widened and he backed up slowly at the horrendous sight of the man.

Dr. Galeia was covered in blood - it stuck to his clothes, matted his hair down, and stained his teeth. His clothes were torn and he was missing a shoe. But what was most concerning to Rodney was how twitchy the doctor was and the insane gleam in his eyes.

"Dr. Galeia," Rondey stuttered, wide eyed. "Wha- what are you doing here?"

"I told them," he ranted, eyes never staying on one place for too long. "I told them all! But would they listen to me? No! They didn't! They called me crazy, tried to lock me up." His eyes now turned to Rodney. "But they all got what they deserved in the end. All of them." He started chuckling like a mad man.

"Look," Rodney started, raising his hands up, "we need to get out of here."

"You're doomed! You're all doomed! They're going to slice you and dice you and eat you." His eyes raked up and down Rodney's body. "You'll be a delicious treat. I think they'll eat you slowly."

"We-we need to get out of here," Rodney continued, voice cracking.

"No one's getting out!"

"Shh! They'll hear us! They'll come!"

"And they should!" Dr. Galeia advanced on Rodney, his demeanor changing suddenly. "You deserve to die! It's your fault we came here! All your fault! You are responsible for our deaths! You deserve to die!" He paused, looking up past Rodney's head, a twisted smile appearing on his face. "I will avenge them all!"

Rodney eyed the gun several feet away - it was just too far. He brought his laptop up as defense, but it was feeble and Dr. Galeia knew this. He attacked Rodney, pinning him against the wall. He reached above Rodneys' head.

The laptop came crashing down upon Dr. Galeias' head but it was already too late. The man had grabbed a coil from the ceiling and wrapped it around Rodneys' head.

The laptop hit Dr. Galeias' head again, this time making him lose his balance and crash to the floor. He started laughing manically. "I have avenged them!"

Rodney gasped, grabbing at the coil around his neck that was keeping his toes from reaching the floor. He kicked out in a vain attempt to squirm out, but he was fastened tight.

"I will watch you die," the crazed man cried. "You will die! You will suffer like I have!"

Dark spots danced along Rodneys' vision as he gasped for the life-saving air he so desperately needed. All he could do was watching helplessly as his attacker watched and laughed.

Slime fell from the ceiling, onto Rodneys' shoe, and he looked up to find a dark shape upon the wall.

There was a horrible hissing sound and more slime dropped.

Dr. Galeias' eyes were wide as he stared up at the menace. "We're all doomed!" he shrieked, backtracking like a crab upon the floor. "All doomed!"

The creature pounced, tearing and slicing at the man in front of it. Dr. Galeia was only able to muster some gurgles as his throat was torn out by the creatures' sharp teeth. Its' tail whipped around, stabbing into the rag doll body while its' hideously long claws sliced into pink flesh. All the meanwhile it was crunching down on bone and muscle.

Blood spurted everywhere, landing on Rodneys' pale face and on the walls, painting a demented picture. Rodney tried to lift his hands, but he couldn't move them. During the time he was attacked he had dropped his laptop, and now his only defense was several feet below him - too far out of reach.

The creature stopped tearing the man apart and turned towards Rodney. Blood fell freely from its' mouth, tail, and claws as it stalked towards him. He could see pieces of muscle still attached to its' claws as well as something that resembled an eyeball staring at him unseeing. It stopped several inches away from Rodneys' face, a horrible gurgling sound coming from deep within its' throat, almost as if it was sniffing him.

The saliva slime dropped from its' mouth, landing on Rodneys' foot and pants, and coating the floor. It slowly opened its' mouth and to Rodneys' horror, a second smaller mouth came out in place if the creatures tongue. The mouth had razor sharp teeth and bit the air infront of him.

Detachedly, Rodney watched as the creature reared its' body to attack. Silently crying, he waited to be torn to shreds.
