Chapter 1: Matt's Warning

Matt was led outside of the Big House (as Chiron had called it) by Chiron. He told Matt that he would stay in the Hermes cabin like many unclaimed demigods had lived before. He saw several activities going on that wasn't in your every day camp. Chiron had told him that most campers were gone until the next summer, but there were still some kids who lived there year round. When they reached the cabin, there was nobody there, as the campers who lived in the cabin were probably out doing half-blood type stuff.

"Did you bring any bags?" Chiron asked.

"No," Matt said. He looked at the clothes that Paul Adams had given to him about a day before. "These are the only clothes I have with me. I didn't have time to get anything because it was an emergency when I went through that door."

Chiron nodded. "No worries. I will find some clothes in your size. I guess I need to get you a tooth brush as well."

Matt decided that he would go along with this until he was back at full power, but after that he would be out of there to start looking for the other four. They exited the cabin and Matt looked in the direction of the downhill part of the camp. On top of the hill, there was a tree with a golden fleece hanging from it. Matt suddenly felt sick. He turned to Chiron.

"Listen to me," Matt said in a strained voice. "There's going to be an attack. Monsters are going to get into this camp and destroy everything.

Chiron gave him a confused look. "Impossible, no monster can get through the boundaries of this camp, it is impossible."

"You don't understand. I SAW it. I dreamed that I was in this exact place. There were hundreds of them."

"Matt," Chiron said slowly. "It was just a dream."

"But this has happened twice, and I've been right both times."

Matt went on to tell him about how he saw his parents die before it happened. He faked being ill, he begged and screamed to not go. They went without him, he let them go to their deaths. He also told Chiron what had happened at his school. How Gwenda Davis, his own aunt, had driven a petrol tanker into the school in an attempt to kill Matt.

Chiron sighed. "I will alert our most elite forces. Matt, if you're right about this, then you will be a great ally. Now go, get some rest."

"No," Matt said. "I want to stay and fight. Trust me, I've had to deal with much greater evil then this. I've had to face the King of the Old Ones."

"As you wish, but if you get hurt, get out of the fight immediatly. Am I understood?"

Matt nodded.

"Good. Now let's find you some armor."

The last thing Percy wanted was for there to be more trouble. He wished he could have just a few months off without there being something wanting to rip his head off. He was in Paul's prius, which had been repaired after Blackjack had decided to park right on top of the hood. The car was very silent. Percy was tired and irratated. Sally was worried, and Paul, well Paul wasn't that worried. He thinks if Percy could beat Kronos, then he could handle just about anything. They eventually stopped near the bottom of Half-Blood Hill.

"This is as far as we can go," Sally said. "It's in your hands Percy, be careful."

"Don't worry mom," Percy assured her. "I've dealt with worse stuff, hopefully."

"Just come back alive."

Percy nodded. He jumped out of the prius with the duffel bag he had packed for his stay. Paul waited until Percy had reached the top of the hill to drive off. Percy looked around the camp. There were more cabins than before. There was one for Hades, and ones for all of the minor gods. It seemed that the gods had kept that part of their promise. He wondered if he was there. He walked into the Posiedon Cabin and set his bag down. He would unpack later. He exited his cabin and started walking towards the Hades cabin. The Hades cabin was made of black marble and had pictures of skulls and other under world type stuff. From where Percy was standing, it looked lke one of those haunted houses that opened up around Halloween. He opened the door and went in, not thiking to even knock first. The inside of the cabin wasn't alot different from the outside. It had a black marble floor and marble walls. There was a black rug in the middle of the room with a skull and cross bones. There was one bed, and on it sat Nico di Angelo.

"Yo, didn't expect you dropping by til the summer," Nico said looking up at Percy with those cold, dark eyes.

Percy shrugged. "Well you know, when your luck is as bad as mne, then things usually don't stay peaceful for long."

"Too true," Nico said. "What does Chiron want with you this time?"

'I don't have a clue. Anything strange been going on?"

"Not really, but we did get a new camper. He apparently appeared out of no where. He's staying in the Hermes cabin."

"Well," Percy said. "If he's not under thirteen, then we're gonna have a problem. I'm gonna go find Chiron."

Nico got up from his bed. "I'll go too, I've been bored pretty much all day."

"Whatever you say."

They left the Hades cabin and started off towards the Big House.

"Do I really have to wear this stuff?" Matt asked looking at the armor Chiron had picked out for him.

"Matt, unless you want to be killed, I'd suggest you wear this armor during battle," Chiron told him. "Trust me."

Matt shook his head. "No, I've made it this far without any armor. My powers will protect me."

Chiron sighed. "If you were a regular camper, then I would make you wear this armor, but you are a Gatekeeper. If you've survived this long, then you should know what is best for yourself."

At that moment, two boys walked into the Big House. The older one had sea green eyes and dark hair. He was wearing blue jeans and a black jacket. It was him, the one from Matt's dream. The other one was dressed in black jeans and an aviators jacket a few sizes too big. He had cold eyes that looked too old to be his.

"Ah! Percy, you have arrived!" Chiron said. The older boy smiled, then turned his attention to Matt.

"Is this the new camper?" He asked.

"Well, technically speaking, no, he is not."

"Then, what's he doing here?" The younger boy asked.

"Boys, I would like you to meet Matt Freeman. He is a Gatekeeper."

The oler boy looked him over, then stuck out his hand. Matt shook it.

"The name's Percy Jackson, good to meet you Matt," Percy Jackson said. He turned to Chiron. "Wait, what's a Gatekeeper?"

Chiron pulled out two seats. "Percy, Nico, It's about time you knew this. The Titans weren't the only evil back in the old days."

They sat down, and Chiron began to tell them the story of the Old Ones.

Jamie Tyler felt like someone had nailed him in the head with a baseball bat. He sat up, taking in his sorroundings. He was in a forest, which was the last place he wanted to be at a time like this. He looked around, hoping to see his brother Scott Tyler. Scott? He called telepathicly. There was no answer. SCOTT! It seemed that his brother was either asleep, or dead. Feeling discouraged, he got to his feet and started walking in the direction in front of him, hoping to find a way out. About fifteen minutes later, he heard voices. He looked through some bushes, and saw a huge clearing beyond them. In the clearing, was a large group of teenaged girls. There were falcons and wolves pacing the area, looking for any signs of danger. One of them had black spiky hair and was dressed in a black leather jacket and black jeans. She was wearing a tiara. She looked sort of like a mix of punk and goth. She put her hand up to silence the other girl's voices.

"What's wrong, Thalia?" One of them asked.

The punk girl, Thalia stood up. "There's something back there. Knock your bows and be ready for anything."
