Chapter 10

Percy woke to the sound of the conch horn blowing. He grabbed his bow and quiver, water bottles, and sword. He ran to the Big House and was attacked by the manticore. Percy slashed at him and then parried the manticore's tail. He looked around and saw the camp was being overrun with monsters. The manticore brought him back to the present by throwing him to the side. He was about to stab him with his tail, when his flank was rammed with arrows. Percy looked over and saw Thalia standing on the Big House's porch with some of her hunters.

"Thanks!" Percy yelled.

"Try to keep up Omega." She yelled back, her other hunters laughing as they ran into battle.

He looked all around and saw his Knights fighting alongside the campers. It made him proud that they could be in this situation and not be killing each other. He ran over to Ethan when he finally spotted him.

"Hey Omega," he said as he dodged an empousa. "What's up?"

"Can you deliver a message to my mom?" Percy asked, slashing the empousa's head off.

"Yeah sure. What do you want me to say?"

"Just tell her that we're fighting. I might not be able to make it tonight. But if Annabeth is there stay back. She was supposed to visit my mom and I can't see her through this mess. Once she leaves, then you can go tell my mom."

"Alright Perce, be careful." Ethan said and then turned and ran back to their cabin where he could make ask Chaos to make a portal into town.

Percy went back into the battle and started slicing and parrying until half the army was demolished in about 10 minutes.

He started carrying the injured to the medics, where Will took them from him and immediately set different campers to tend different wounds.

"Omega!" Thalia yelled from across the field.

He ducked and spun around drawing his sword. Standing there was the Minotaur.

"Sir they're here." Stephen spoke to the distorted image of Ouranos.

"Good. What of Perseus Jackson?" He asked.

Stephen looked out of the window of the attic and saw 'Omega' fighting the manticore. "He's fighting the Minotaur at the moment. What happens if he kills all of the monsters?"

"Sir." Ouranos demanded.

"What happens if he kills all of the monsters, sir?" Stephen corrected.

"Better. And if he kills all of the monsters, then we'll try again tomorrow. Nyx is working on having Tartarus join our cause. That ghastly boy never listens to her reasoning." Ouranos ranted.

"Men shouldn't listen to women, they are unreliable and emotional."

"Stupid demigod, women are wise beings! They are intellectual and men often have to rely on them to know what to do." Ouranos shouted.

Stephen then heard footsteps coming from the stairs. "I must go there's someone coming. I will call back when the battle is over." He waved his hand through the image of Ouranos and it disappeared. Next he grabbed his cloak and pulled it around him to make him invisible.

"Come on, no one's ever up here." he heard a girl saying. It sounded like the huntress, Thalia.

"Fine, but make this quick. I have to help the camp." Stephen recognized the sound of a voice modifier. Maybe it's Omega.

They opened the door and lo and behold standing before him was Thalia and Omega. They left the door open and went to the chair that the old Oracle of Delphi had occupied for several hundreds of years. Omega pushed Thalia into it and bent down and started kissing her. Disgusted Stephen left.

Thalia pushed Percy back and he walked over and closed the door.

"Gah, what the hell was that for!" She screamed at him.

"Someone was in here. We have a spy in our midst. I was hoping they would leave after seeing that, and they did." He shrugged and slouched in the chair she had just gotten up from.

"At least warn me next time," she said wiping her mouth on her sleeve. "Ugh it's like I just had a make out sesh with my brother!"

"What did you bring me up here for Thalia?" He asked, impatiently calm.

"Someone wanted to say hi." Thalia said and shrugged. She whistled and then left the attic.

"Can I leave too or… and you're gone. I'm only staying five minutes, if someone doesn't come I'm going to go back into battle."

"I see why they called you Persassy." Artemis said coolly, stepping out of the shadows.

"Of course Thalia told you." Percy rolled his eyes. "You here to kill me? To drive me away again, make sure I never come back?"

"Percy," she sounded hurt. "I would never. Thalia didn't just tell me who you were. When everyone was driving you away before she showed me the letter you gave her, she explained to me what all had happened. I seeked out Aphrodite and she told me how worked up you got when you were talking about Percy, or... yourself."

"And so why am I here?" Percy asked. This conversation was going nowhere and he wanted to kill those monsters so he could talk to his mom.

"Just now you kissed Thalia, why was that?"

"Um, there was someone else in the room trying to hide from us."

"And how did you know this?" She asked calmly.

"I learned a few tricks when I was training with Chaos." He answered, now nervous. "It was a spy to my belief and Thalia didn't know I was going to do it. She still is loyal to your oath m'lady."

"Oh I know Percy. It was actually quite funny to watch as she freaked out." Artemis laughed, it was quite a beautiful sound. "That's not what I'm interested in. No, I'm interested in the spy. Could you read anything from him, or how does it work?"

"I think it was Stephen. I heard someone talking in here before Thalia and I walked in, and when we opened the door I heard the sound of fabric moving. When I walked past where you're standing now, I could feel the presence of someone right next to me. This isn't that big of a room and it's quite easy to know if someone else is here."

"What is it you talked to Aphrodite about? I know it wasn't love trouble, but she doesn't major in much."

"The same topic me and you are discussing Artemis. Why? You jealous?" He smirked.

"Don't be cocky, you'll start to sound like Leo."

His smirk faltered when she mentioned Leo, and she frowned. "Is he okay? I haven't seen him but twice and we haven't talked at all."

"He's doing fine, he's in Cabin 9 right now with Calypso, trying to find out how the monsters got in." she replied softly. "You must go now, finish this battle, we'll talk more on this spy later."

He hugged her and she stiffened, but then loosened up. "Thank you Artemis, I'll see you soon." He ran down the stairs slamming the door behind him, and jumped back into the battle.

"I don't get it! How could they have gotten through without Bad Boy Supreme knowing?" Leo yelled punching his work table.

"Maybe it's something simple that we ruled out." Calypso said calmly rubbing soothing circles on his back. "Let's go over all of the reasons monsters can get into the camp again."

"Alright, yeah that sounds like a good plan. The easiest way is if someone let's…" He stammered to a stop. "Someone let them in!"

"Alright, but who would do that?"

"Last time there was a big war, we had spies all over camp. It could be someone we know, or maybe one of the Shadow Knights. Why would they pick that name, there's so many cooler options that they could've chosen."

"Leo, focus." Calypso said.

The door opened and Leo looked over. Standing there was a Shadow Knight. "Speak of the devil." He said. There weren't that many people that knew how to get in here, less so that were dead or presumed so.

"What?" The Knight asked, tilting his head.

"Not many I know know how to open that door." Leo said. "Who are you? Are you a spy?"

"Even if I was I wouldn't tell you. But no I'm not." The Knight confessed.

"Can you tell us who you are then?" Calypso asked.

"I'm not supposed to, but for Caleo, I will." The Knight waved his hand and the door closed. "Is there anyone else in here?" He asked.

"There shouldn't be," Calypso said.

"Would you mind if I looked around?" He asked. They shook their heads and he set off going around the room.

"Why would anyone else be in here?" Leo asked.

"Well you did think I was a spy." The Knight countered. "And anyways, it's always nice to be safe not sorry." He searched around cabin 9 in all of the rooms and corners. He must not have found anything since he came and looked at the desk, once again tilting his head. "Get mad did we?"

Leo looked down and saw his fist left a burnt impression on the desk. He was lucky he didn't have any papers there. That had happened before and that was how most blueprints were lost to him. "Heh, um yeah. I couldn't figure out how the monsters got out." He rubbed the back of his neck and Calypso came over and put her hand on his shoulder.

"Well that's easy. Someone let them in." The Knight stated.

"How do you know this? Better yet, who are you?" Calypso asked.

"It's only been five years and you can't guess at who I am?" The Knight asked shaking his head. "Which of your friends 1- knows where this bunker is, 2- knows how to open it, and 3- is dead,or presumed so?" He asked.

"But it can't be," Leo said.

"Who is it? Who are you?" She asked Leo and then the mysterious Knight.

He took of his hood to show that he was- "Percy!" She yelled and ran and tackled him in a hug. "I thought I'd seen the last of you! I'm so glad you're back, does your mom know? She was so broken inside when you left. And that wretched Annabeth told her you were dead. I'll never be sorry again for cursing her. How could she?"

Percy laughed and hugged her back. "My ma is fine and I want to thank you guys so much for visiting her." When he let go of Calypso, Leo hugged him too.

"So you came back only now to visit your Captain Supreme?" Leo asked. Percy laughed again and slapped Leo on the back. "So, does this mean you know who the spy is?" Leo asked sitting at the desk.

"Yes, but so far only me, Chaos, and Aphrodite know. We need to learn more about him and his powers before we can expose him." Percy answered warily.

"What? Can you not trust us Kelp Head?" Calypso asked.

"I'm sorry my trust has been a little off recently. I showed you who I am, now I shall tell you who the spy is. It's Stephen, the charmspeaker." Percy replied sadly.

AN: Sorry, it's been a while since I last updated. I am having some issues at home and I am having writers block with chapter eleven, but I hope to give you at least 2 chapters next month. I will be getting ready for finals next month though, so I'm not sure how far I will get. Peace, percbethhippie
