Revised on 5/8/11.

"We don't have weather," Zac said, rolling his eyes. He sounded agitated, while I, on the other hand, was completely entranced with the thought of weather. Sure, we had sunlight—thanks Hyperion—but nothing besides that. I had always wondered what it would be like to have such strong winds that could knock down buildings. It's just… unthinkable.

"Oh, bummer," Percy muttered, shaking his head.

No one said anything more, so I looked around in the darkness. Since the mirror glowed—or rather, put off a slightly luminescent field—I could faintly see. We were standing in what looked to be a long, never-ending hallway made of stone. It was cold and you could feel a slight breeze.

"Where are we?" I asked Zac, brushing his fingers with mine. Electricity bounced at the touch. It wasn't an uncomfortable shock, but a soothing one.

"I don't know," he muttered, "but I have a feeling that no one's been here in a long time."

"I know, me too. It has an odd feeling… like something tragic happened," I murmured. A voice seemed to whisper inside my head, Death. Lots of death. I shivered involuntary. I had a feeling the voice was right.

I heard a door slam and Annabeth's voice call, "Jemma? Zac? Are you still here? Or there? I guess either one would be correct. And you would answer the same either way…" She trailed off.

I held up the mirror so that both Zac and I could see into it. Annabeth was sitting at a desk with something I had never seen before. It was the size of one of our text books—a text book sitting on its side, open. There was a screen on the back side that was lit up. I raised an eyebrow.

"What is that?" Zac wondered aloud, cocking his head to the side.

"What?" Annabeth looked around, confusion on her face. Her eyes trailed back to the box-type-thing on her desk, then asked, "They don't have computers in your futuristic world?"

"Huh?" I didn't understand what she said, so I said, "I've never seen one of those before."

I heard Percy say to Nico, "Hold the mirror. I need to ask them a question." Then there was some swirling colors and Percy was sitting next to Annabeth.

"What question did you want to ask us?" Zac said.

"You guys don't have Facebook?" Percy asked, his eyes wide. He threw hands up in the air in an exasperated manor.

"Uh… Facebook?" I asked. What's Facebook? Do they paste pictures of people's faces on books? If that's the case, then I suppose we would have Facebooks. But why would Percy be so surprised?

"OH MY GOSH! Can you believe this? They've never even heard of Facebook. What do you do without FarmVille?"

"FarmVille?" What the heck is he talking about? Is it a farm or a village?

"Yeah, or any of the other awesome games on there. I don't see how you live!" Percy laid his head down on the desk.

"Nobody cares about your farm, Perce," Nico muttered.

"I knew it!" Annabeth said, evidently completely unaware of the conversation that had just taken place.

"Huh? What?" Percy yelled, raising his head up.

"Miss Smarty Pants over here found her answer," Nico said.

"Well?"

"Well… Apparently Daedalus had a theory," Annabeth began, "as to how this might happen."

"Wait, who's Daedalus?" I asked.

"He invented the Labyrinth," Nico said coolly.

"And a bunch'a other cool stuff!" Percy concluded, grinning.

"Right," Annabeth said, glancing over at Percy. "As I said, he had a theory."

"And that theory is?" Nico asked, sounding depressed.

"It's kind of hard to explain," she said, frowning. "I had trouble grasping the concept at first, so—"

"So you're going to have to dumb it down for us," Percy said lightly, touching her elbow.

She took a deep breath, then said, "I think what he thought was that for every choice you make, in some alternate universe, the other side to that decision is chosen."

"Erm… What?"

She frowned again and I smiled. Her eyes were moving very, very fast, reading the data on the screen. I was fairly certain she was calculating very complex problems in her head. "For example," she finally said, "every time you make a decision, even one as simple as wearing a hat that day, in some other world, you chose to not wear a hat."

"So there's another me?" Percy asked, raising his brows.

"There's an infinite number of yous, as scary as that sounds," she whispered that part, then spoke up again. "There's an infinite number of everyone in an infinite number of alternate universes."

"Sweetness!"

"Like, in one world, you may have died as a child, so you wouldn't have been the next child of the great prophecy; it could have been Nico. In another world, Nico could have died the same time his mother was killed—" Nico winced as she said that. Annabeth continued, not missing a beat, "thus creating the need for some other hero."

"Uh, right," Percy mumbled, looking up at Nico, who was holding the mirror. He must have mouthed something, because Percy snickered.

"How does this tie in with us?" I asked.

Annabeth said, "You're living in an alternate universe, where unfortunately, Percy lost against Kronos, and he took control over the world."

"Holy guacamole, that's confusing!" Percy exclaimed.

"And that's why your head is filled with kelp," Annabeth snapped.

Zac laughed—a quiet laugh, but a laugh none-the-less. "Who's to say that it's you that's living in an alternate universe where Lord Kronos lost against Percy?"

Annabeth frowned, her brows furrowed. "I—I guess you could look at it that way."

"Okay, but what about the mirror?" I asked, glancing over at Zac. Sometimes the things he said really threw me for a loop. Now was a perfect example of such a time.

"We found these mirrors on purpose. That means that we'll be using them in some shape or form. You know… no, that's impossible… well, not impossible…" Annabeth began talking to herself. "It's actually highly probable, factoring in the recent events…" Then, she picked up her laptop and swiftly walked out the room.

"You know, sometimes I wish I could read her mind," Percy said.

"Why? You wouldn't understand what she was thinking anyways. She's too scientific," Nico commented.

"Yeah, still…" Percy mumbled, his face thoughtful.

Zac put down the mirror—I had handed it to him after my arm had went to sleep. "Do you believe what that Annabeth girl was saying?"

I was going to say yes, but I hesitated. Why should we believe them? We didn't know them. For all I know, they could be psycho maniac killers! But, what she said did make sense… sort of. And besides, I was certain it was the Annabeth, the Annabeth our history books briefly mentioned. Her intentions—if you read between all the lies of the book—were actually good. I nodded. "Yeah, I believe her."

"Well, if you trust her, then I do too," Zac said, placing an arm around my shoulder. He shocked me, and I wondered if it was all in my head. He didn't even act like he felt anything. Maybe he didn't. Maybe I was going crazy.

Setting the topic of my sanity aside, I said, "Now then, how do we get out of here?"

"I was wondering the same thing myself. Maybe one of them will know." Zac lifted up the mirror and yelled, "PERCY!"

Percy jerked his head around and said, "What?"

"Have you ever been inside this room before?" Zac gave a slow, 360 degree view of the place.

"That looks like… the entrance to the Labyrinth." He shivered as he said that, his eyes suddenly seeing something other than the room he was in.

"The same Labyrinth that the Daedalus guy built?" I asked, thinking back to our history book. The Labyrinth had been a very strategic area for invading the camp where demigods were trained. If we were in that same place…

"Uh huh," Percy whispered.

"What's wrong with it?" Zac asked.

"Oh, it's nothing." Percy shrugged his shoulders nonchalantly. His eyes were what gave him away, though. They seemed to hold a sadness—a sadness that could only be caused by death. "We fought a battle there, and a lot of people died…"

There was silence on both ends, as what he said sunk in. Just how many people had died in here?

The voice in my head answered with a simple, Lots.

"So you've been in here, though?" Zac asked.

"Yeah."

"Can you tell us how to get out?"

"Sure. First, you've got to go to a wall and feel along it for an indention. Once you find that—"

I felt an indention, so I pushed it. Suddenly, light erupted, shocking my poor retinas.

"I think we've got it from here," I said as I climbed out and into the openness. I helped Zac up and then we looked for Chad, Sarah, and Donnie. I couldn't see them. Hyperion was pulling the sun across the sky. Wait, what? When we'd gone into the Labyrinth, it was about ten o'clock. Now… I'd say it was nearing four in the morning. That couldn't be right. We hadn't been in there that long, had we?

"What the he—"

"I don't know what's going on," I whispered, reaching for Zac's hand, which I grasped eagerly.

"Chad? Donnie? Sarah? Anyone?" Zac shouted.

No response.

"Hello? Where are you guys?" I yelled, craning my neck frantically to see if they had wondered off somewhere.

I heard someone mutter, "Over here." I followed the voice and discovered the three lying down under the over-hang of a rock. They were all rubbing their eyes. They had been asleep.

"Where did you guys go?" Donnie asked. "You were gone for a long time."

Zac shook his head. "It felt like we were gone for thirty minutes tops."

"Yeah, I know. It didn't feel like we were gone for long at all."

"Hey, uh… Jemma and Zac?" Annabeth's voice rose from inside Zac's pocket. He pulled out the mirror and held it up so all five of us could be seen.

Chad looked over at me. "What's going—"

"Hi! I'm Sarah!" Sarah said happily. The fact that our reflections weren't staring back at us didn't seem to bother her one bit. She was practically beaming.

"Hi Sarah. It's nice to meet you. I'd like you guys to meet Chiron. He'd like to talk to you guys about the possibility of a quest."

Thanks for reading. Reviews are appreciated. :D
