Prologue

…Many Moons Later…

Dr. Daniel Jackson spent several days trying to remember what had happened in the cave with the sea creature, Nem. All he could recall were images of the desert sands and a pyramid. He told himself that those were memories of Abydos that the creature had him recall and he had himself firmly convinced.

It had been nearly eight years since he thought of anything having to do with that creature and that underwater cave. Many things had happened from then 'til now. 'So what made me think of it now?' he wondered to himself as he looked around the perimeter of the clearing they stood in early that morning. Daniel looked at his fellow teammates as he took in the dense jungle beyond the area of the 'gate.

"Come on, Daniel," Colonel Jack O'Neill said as Teal'c and Major Samantha Carter headed toward a cut path that SG6 had made into the overgrowth during their stay on this planet. "Let's go find your rocks," the Colonel said as he waved his hand in that direction.

"It's a ziggurat, Jack," Daniel said as he rolled his eyes, adjusted his glasses and filed in behind Sam as Jack took the rear.

Looking up through the trees, Daniel noticed the twin suns as they gleamed down on them. A large planet loomed over the atmosphere and if he concentrated, Daniel could feel the pull of its great mass. He could also see a few satellites. This "planet" and the others revolved around the large planet that the other SG team had affectionately dubbed Large Marge.

"How long did Colonel Sumner say it would take to get to the ziggurat?" Sam asked as she turned to look at her other teammates.

"Marshall said it took about an hour to reach the rocks," Jack said with a smirk.

Daniel rolled his eyes ignoring the comment as he continued to follow the others through the dense jungle.

An hour later the four team members of SG1 reached the vine covered ziggurat.

"How will we get inside the thing?" Jack asked as he looked along one side and back down the other.

"Well, we have to pace the perimeter," Daniel said with a frown as he realized he was taking on more and more military lingo. He shook his head as he continued along the stone side, "There should be a face carved in stone, the mouth will be the opening."

"Carter, you go with Daniel," Jack said as he scanned the area, "Teal'c and I will head to the right. Give us a holler if you find it first."

"Yes, sir," Sam said as she trotted over to Daniel. "So what do you think is inside?" she asked as she followed him.

Daniel shrugged as one of his rough hands trailed along the side of the rocky surface of the large stone bricks.

"Do you think it might have anything to do with the Lost City?" she asked as she watched her friend.

"I don't know, Sam," Daniel said with a slight smirk, amusement played in his blue eyes as he looked over at her.

After walking along side the pyramid like structure, the pair finally turned the corner of the ziggurat and they gazed at the face carved in the surface.

Daniel grabbed the camcorder hanging off the strap on his backpack; he began to take a video recording to file into the computer when he got back to the base. "Oh, wow, Sam!" he sounded so excited, "This is amazing! This is the first time humans are actually able to see temples of Mayan or Aztec construction without destruction from time and elements clouding the view."

Sam chuckled as she radioed their position to the others and followed him to the entrance of the ziggurat. "It's pretty impressive," she responded as she looked at the stone face bulging out from the surface of the structure. She watched Daniel as he strode to the front of the entrance, she noticed him sag in disappointment.

She quickly headed over to him, "What's wrong, Daniel?"

Daniel looked over at her as he spoke into the hand held recorder, "There's a stone locked into place that blocks the entrance, there has to be a lever or something that will open it from the outside…" he pressed pause on the digital recorder when Sam reached his side.

"The stone is in the way," Daniel said as he examined the face.

"Any chance of blasting the stone away with dynamite?" Sam asked with a slight teasing light to her blue eyes.
