Crystals P.O.V.

The palace was amazing. I didn't have time to take it all in before Poseidon and Percy led us into the palace and we were standing in a beautiful ballroom with a huge crystal chandelier. (I know, Crystal, crystal chandelier, it's actually really annoying when people remind me.) Mysti and I have this weird twin thing. We're not sure if any other twins have it, but we do. Whenever we don't want other people to hear us talking, we sort of talk inside each other's head. So I started to hear my name inside my head and I responded with Mysti. Crystal! Can you hear me?Mysti said. Yeah I can, I said.
Great! I needed to tell you something, and I didn't want them knowing, Mysti nodded her head to Percy and Poseidon who were deep in conversation. Percy looked really sad, like his favorite thing had just been taken away. I didn't think about it, and kept going with the conversation.
Okay, what is it? I asked.
There are dolphins stalking us in every window of this room.
I looked around, and she was right. Out of every window there were six or seven dolphins staring directly at us.
OK, now it's freaky, I said.
I KNOW RIGHT! Mysti said, it's starting to scare me..
I have an idea, I said, just follow my lead.
She nodded, and as I was about to say something, I noticed Poseidon was gone and Percy was staring at us. "Why are you staring at us?" I asked Percy. "Oh," he said "both of your eyes were glowing blue and green, and you guys were acting like you were having a conversation, but in your heads."
"Oh, about that.." I said. Before I could finish Percy interrupted, "We should probably head back up, I think it's about dinner time."
"Ok" Mysti said.
We headed back up and in a little but we were walking out onto the beach at Camp Half-Blood. When we got out, Mysti and I were completely soaked, while Percy was perfectly dry. "Percy," I said,"how are you dry?" "Oh!" he said, "it's one of the powers that comes with being a child of Poseidon. Just imagine your dry, or that all the water is just falling off you, and you'll be dry." Just like that, Mysti and I were completely dry. "That is so awesome!" Mysti screamed, "Can we do anything else?" "Yeah," Percy said, "but I can give you lessons tomorrow, you must be tired and starving."
We went to eat dinner then Percy took us to the 'Poseidon cabin' and he pointed at a bunk bed and said "You guys can sleep there, if you want, I can bring you breakfast in the morning. After I sacrifice it.." "Thanks Percy!" Mysti said, then she laid down and fell asleep almost instantly. After I was sure she was asleep I said "Percy?" "Yeah?" He said. "Can I talk to you about something?"
"Sure."
"Ok, well when we were at Poseidon's palace there were windows all around the room, and there were about six or seven dolphins staring directly at me and Mysti through those windows."
"Oh," Percy said "Well, until you guys, I was the only known son, or child, of Poseidon in the world so I guess they were just surprised."
"Ok" I said "Can I tell you something else?"
"Yeah of course."
"Well when you saw our eyes glowing blue and green, we were actually having, you know, a mental conversation. Is that a twin thing? Or is it just us?"
"I have no idea," Percy said "I can ask the Stolls in the morning, they're twins."
"Okay, thanks Percy." I laid down and fell asleep.

In the morning I woke up, only to see a creepy Leo standing next to my bad with a plate of food. Mysti was already eating hers in her bed, but Leo was just grinning at me. "Uh, Leo?" I said "What are you doing?" It's not that I cared, I was just curious. "Oh, Percy asked me to bring you this." He said, still grinning.
"Thanks"
Leo handed me my plate then left, probably back to his own cabin, so I started eating. I took the first bite of my pancake, and then spit it out. There was a piece of paper inside of it. The paper read:

Meet us by the camp entrance tonight at midnight. Bring Mysti.

"Mysti," I said "stay awake tonight."
"Why?" She said.
"Because at midnight were going to the camp entrance."
"Wha-" Mysti started, but I interrupted her by handing her the note. "Oh." She said. "Hey want to go find Percy?" I asked "He promised to give us lessons on our powers remember?" We went outside and started to walk around camp looking for Percy when we found him near the Hermes cabin. (At least, I think it was the Hermes cabin. Not so good with the cabins yet...) He was talking to two boys who , by the looks of it, were twins. "Ok thanks guys, I'll tell my sisters." Percy turned around and yelped, because we were standing right behind him. The twin boys burst into laughter while me and Mysti just grinned at Percy. "Can you give us those lessons you promised?" Mysti said. "Yeah sure, as long as you never do that again." "No promises" I said. "Oh fine I'll give you the lessons anyway."
"YAY!" Mysti and I screamed in unison.

Percy's P.O.V.

We walked down to the beach so I could show Crystal and Mysti their powers. When we got there I said "Hey Crystal, did Leo tell you?" "Yeah, he put a note in my pancakes.." I decided not to ask. "Alright, I'm going to show you something and your going to mimic it with your powers, okay?" "Okay" they said. I raised a small wall of water in front of me, then sent it back into the ocean. Crystal and Mysti stood up, held hands (for what reason, I have no idea. Must be a girl thing,) and raised a gigantic, at least forty foot tall, wall of water. The wall soon turned into a circle, blocking my sisters from my view. Suddenly there was a part in the circle-wall and Crystal and Mysti walked out, then sent the wall back into the ocean. "Like that?" Mysti asked.
"I think you guys should be giving ME lessons." I said, in awe of what they just did. It was amazing, and they didn't even look tired! The girls laughed, and I said "How did you even do that? Where did you get the circle-wall idea from?" Crystal and Mysti exchanged looks, and Mysti said "I saw it in my dream, we hold hands and do that, as you put it, circle-wall thing."
"And your not even tired? Not even a little bit?"
"Nope."
All I could say was "Wow."
Then Crystal asked "Can we get on with the lesson? I want to go see L-" she stopped herself and said "Annabeth, I need to ask her some stuff about Greek mythology. "
"Yeah okay." I said. I would follow her later, I decided. "Next thing, mimic me again, alright?" They nodded. I raised a trident made of water out of the sea and brought to my hand. I held it for a second then sent it back to the water. "Okay, your turn." I said. They both raised a trident the same way I did, then sent it back. "Okay, next-" I started to say, but was interrupted by Crystal, "Wait! Can we make one more thing out of water?"
"Sure" I said "like what?"
The twins looked at each other, then said in unison "A gummy bear." That took me by surprise, I mean a gummy bear? Why? "Umm okay..." I said. They made a huge gummy bear out of water, then looked at me, grinning. They sent it back into they ocean and said okay were ready for the next one. I told them mimic me again and then created a storm, raging winds, enormous waves, and told them to do the same. They held hands again, and created the biggest storm I had ever seen. I screamed over the wind "STOP!" The winds died down, and the waves went back to normal. "Now are you guys tired?"
"No" they said.
"Oh my gods you guys, that's amazing. And I'm exhausted so I'm going to go sleep, go do whatever." I walked back to the Poseidon cabin and on the way I saw Annabeth, and she said "Where you going Seaweed Brain?" "I'm going to go take a nap."
"Why?" She asked "You tired from making that huge storm?"
"You saw that?" I asked.
"Yeah. The whole camp saw it."
"Oh. Well it wasn't me. It was Crystal and Mysti."
"What!? It was them?" She asked, perplexed.
"Yeah" I said "the first part was me, then it was them."
"Are they coming to sleep too?" She asked.
"No. They weren't even the slightest bit tired." With that, I started to go inside the Poseidon cabin when I remembered, "Hey Annabeth, Crystal's looking for you."
"Okay, thanks Percy. Now go to sleep." She said with a smile.
I went inside and instantly fell asleep on my bed.

Annabeth's P.O.V.

I tried to find Crystal and I saw her and Mysti coming back from the beach. I went up to them and said "Hey guys. Percy said you were trying to find me?"
"Oh," Crystal said "about that..."
"Let me guess, it was a lie you told Percy to get him off your back?" I asked.
"Yeah." Crystal said.
"Okay, no problem." I said. Before I could walk away though, Mysti said "Hey Annabeth? While your here, I was wondering if you could teach how to fight with a sword or dagger or something."
"Sure." Follow me.

Crystal's P.O.V.

I'm glad Annabeth understood, or that would've taken some explaining. I was going to see Leo, I needed to ask him about the note, and who "us" was. I was walking toward his cabin when I bumped into him. "Hey Leo! I need to ask you something about that note.." "Shhh..." he said, " is incognito." "Umm okay.. See you tonight then." I said. Then I ran away.
