We went into our special rooms. It was like we were on the Argo II again but our rooms were different. On the doors it had the symbol of our parents. My room had a dove on the door and my cat charm was in it. There was a room with a trident and an owl. Percy and Annabeth's room. They had to share a room because of the dreams from tartarus. Everybody went to sleep.
----------------------Percy's POV-------------------
Me and Annabeth has a room together sweet. Their was separated beds of course but we needed to be in the same room together to handle the dreams.  Smarty and Nemo was already in our room. So we went to sleep. I was having a dream but Annabeth woke me up. She was tossing and turning. So I went to comfort her.
-------------------Piper's POV----------------------
I had a bad dream last night.
I was in this room when a man came in. "How do we resurrect me again." The man said and I realized he had no nose. "I told you I have found a way but it is not time yet" a women's voice said. "But Gaia when" the man said. No no no not her again. "Shh do not speak of the plan we have a demigod listening.
Then Jason woke me up. "Pipes it's time for breakfast." Jason said to me. I had a dream and now we have a problem" I said. I told them my dream and they were not happy. "I died putting that women to sleep. I do not want to do that again!" Leo yelled. "And we went to tartarus and barely survived." Percy said. "We will talk about this later it is time for breakfast in the great hall." Jason said. So we all went to breakfast and sat down. Those three kids came up and asked if they could sit with us. Well we of course said yes. We have to learn what happened to this Harry Potter and fix him. Once everyone was seated Dumbledore made an announcement. "As you all know classes start tomorrow. So today you can anywhere around Hogwarts except the Forbidden Forest. That is all you may eat." Then our food appeared. "Annabeth?" Percy asked. "Yes Percy." She replied. "I saw a lake can we go there today?" he asked. Annabeth thought about this for a minute. "Fine, but after you have to study with me and" she said. "No being under water for a long time" Annabeth said in Greek. "Fine. But what if we have a contest?" Percy asked. She said it was okay and then the wizard asked if they could come. "Yeah sure" Hazel said. We all went and put on our swimsuits. All the girls were in bikinis except Hermione who was wearing a one piece.
----------------------Third Person-----------------
Annabeth was wearing a gray swimsuit bottoms and a sea green top. Piper was wearing a pink bikini, Hazel was wearing a black bikini, Calypso's bikini was white with pink polka dots and Hermione wore a red swimsuit. Percy wire his blue swim trunks. Jason and Nico put on electric blue and black swim trunks even if they were not going into the water. Will had yellow ones,Leo had Fire pattern. Franks was green,Harrys was red and Rons was brown.
----------------------Piper POV---------------------
We all went out and set out our towels. Me,Annabeth,Nico,Jason and Hazel sat down on our towels. Percy ran over "why are you guy not in the lake." Percy said. "If you want all of us in the lake we have to contact your dad Seaweed Brain." Annabeth said quietly. She told the wizards to stay here and that we will be right back when we went far away from where they are. Percy made us a spout of water. "Oh Iris Goddess of the rainbow receive my offering." Annabeth said while she put in the drachma. "Poseidon" then Percy's dad's face showed up on the screen. "Oh hello Percy what do you need from me?" Poseidon asked. "Hi dad I was wondering if Hazel,Nico and Jason could go swimming?" Percy asked. "Sure son. Is that all because I have things to do." Poseidon said. "Yep. That's it dad." Percy said. Then we swiped through the mist and went back to where the wizards are.
