"SG-1, you have a go," Hammond's voice boomed from the control room. Jack nodded to them, making sure they were all ready to go, and headed up the ramp. Teal'c took up the rear, following Daniel. They stepped through the Stargate.
In a flash, they were there. Jack was already scouting ahead, making sure there weren't any bad guys waiting around the corner. Daniel looked around in awe, and wondered how this civilization had come to be here, as there was no evidence of ventilation shafts, or even a way to get the Stargate in there. He ran his fingers along the glyphs on the walls, wondering who had carved them, and how long ago.
"Well, Carter? Which way do we go?" He indicated the two different tunnels, leading in opposite directions.
Sam took out her instruments to determine which way the energy waves were coming from. "That way, Sir," she said, pointing to the tunnel on the left.
"Then that's where we're headed. Daniel, stop playing with the walls. Teal'c, watch our six." With that, he motioned for Carter to take the lead, and followed her through the tunnel.

"Wow, this is amazing!" Daniel exclaimed, running his fingers along the walls. They were in a large cavern, larger than any cathedral Daniel had ever been in. The ceiling was so high, their flashlights didn't light it. Spikes of crystal shot up from the floor along around the edges of the cavern. "The crystal is perfectly smooth. It seems natural, but the tunnels had to have been man-made. Or alien-made," he amended. He knelt to pick up a piece of a crystal, which seemed to have fallen off the crystal spikes somehow. Teal'c didn't wait for him, knowing he would catch up with the group once he'd put the crystal in his pocket. Daniel examined the strange pink sheen of the crystal, fascinated by the lights that danced within it. He stood up and put it in his pocket, turning to catch up with his friends.
"Daaanieeel" The voice sounded feminine, and far away.
"I'm coming, Sam!" Daniel shouted, closing the Velcro flap on his vest pocket and running to catch up with them.
He ran up ahead of Teal'c, and caught up with Carter. "What?" he asked her, breathing heavily. The air was a tad thinner on this planet than Earth's.
She looked up at him from her instruments. "Hmm? What is it, Daniel?"
He looked at her, puzzled. "Didn't you just call me?"
She wrinkled her brow, equally puzzled. "No, I didn't." She shook her head.
Daniel looked around, trying to figure out who had called him. "Jack? Did you call me? Teal'c?" Both his friends answered in the negative. "Huh. Okay. I must've just – imagined it. I guess," he added softly, still quite sure that someone had called him, but knowing his friends wouldn't lie. He gazed around, suddenly not quite sure that they were alone.

After about an hour, Jack called a halt. Sam said the energy readings were getting stronger, but that could just mean that the power source was much more powerful than they had anticipated, and that it was still quite far away.
They all sat down in a small cavern they'd come across, accepting Teal'c, who stood against a wall. They broke out the food, and took a much needed break. They were all eating quietly, enjoying the silence between them, when Jack looked up. "Hey, does anybody feel that?" he asked. "It's sort of like a vibration… No, more like loud humming. I didn't notice it till we got to that one huge chamber back there. It's gotten louder since then."
Teal'c nodded, having noticed it even before the colonel had, but not mentioning it. "I have heard and felt it, O'Neill."
Daniel was gazing off into space, as if he saw something there. "Daniel, didja hear me? Daniel!" Jack yelled at him.
Daniel jerked back to the present, startled. "What?"
Jack sighed. He hated when Daniel got wrapped up in the language and history of a planet. He was probably thinking about the symbols in the Stargate chamber. "I said, have you felt or heard any strange humming?"
"No, I haven't."
Jack looked at Sam. "Me neither," she told him, wondering how it was that Teal'c and Jack were hearing something that neither Daniel nor herself could hear.
Jack stood up. "Oookay, then, I guess we're just hearing things." Teal'c didn't think so, but he didn't say anything about it. "Come on, Campers, we've still got a lot of crystal to cover!" he said with a grin as everyone else stood up.
They had all started to follow Sam, when Teal'c told them to hold. They looked back, and saw the Daniel was walking quickly back the way they'd come. He didn't look right; something in the way he was striding eagerly forward without seeming to see where he was going made the hair on the back of Jack's neck stand up. "Daniel, come back here! Daniel! DANIEL!"
