So this is my new story, which I'm super excited about! As far as I know, this will be the first of five stories with this AU. This is my first time writing an AU story, but I think it'll be good.

As for a disclaimer, I don't own Percy Jackson and the Olympians, or The Heroes of Olympus. And I'm obviously not Rick Riordan. If either of those were true, I would not be writing on FanFiction.

And now for the story! =)

Prologue

Four demigods were shuffled into the throne room, where the king titan Kronos sat on his throne, looking extremely bored. The demigods were wearing worn, tattered clothes. Three girls and one boy, each branded with the titans symbol, as if they were no more than cattle. In reality, they lived lives worse than cattle. They were slaves to the titan lords. As they were pushed into the throne room, Kronos smiled; an evil, chilling smile that didn't help the four demigods feel any better.

"Ah, my entertainment is here," the titan said happily. "How shall you be entertaining me today, slaves?"

One of the girls winced, and then stepped forward. She was a daughter of the goddess Hecate named Lou Ellen. She used no surname.

"My lord," she said with a meek bow. Her ratty clothes hung very loosely on her bone thin figure. "We have a presentation for you. We will show you whatever scene of your past you wish to see, or perhaps another topic that interest you."

Kronos thought for a moment before answering. "Show me my greatest victory. Show me how my retched children tried to overthrow me, but did not succeed."

Lou Ellen nodded and turned to the boy. His name was Charles Beckendorf, but almost everyone called him Beckendorf. He was a son of Hephaestus, and out of the four slaves, he looked the healthiest. Beckendorf worked in the titan forges, but wasn't allowed to actually build anything, except when supervised by a guard. He mostly just helped transport materials for the telkhines to use. Beckendorf was pretty strong, and he could create almost anything. When Lou Ellen looked at him, he pulled a small box out of his pants pocket. Setting it on the ground, he pressed a button and the box expanded until it was the size of a dinner table.

"This, my lord, is a projection machine," Beckendorf explained. "It, with some magical help from Lou Ellen, will let us show you the story you want to see."

He turned the machine on and typed a code into it, telling it which story to show. The machine buzzed and whirled, and then the light at the front of it came to life and projected a holographic image of the ancient Mount Othrys.

"Silena and Drew will narrate," Lou Ellen said.

The other two girls- Silena and Drew- positioned themselves so there was one girl on each side of the projection. Beckendorf and Lou Ellen stood behind the machine.

Silena and Drew were both daughters of Aphrodite. Drew was gifted with the ability to charmspeak, meaning she could charm people into giving her anything she wanted. Unfortunately, the titans and the majority of the slave keepers were immune to her power. Even so, she still had a very powerful voice… one that made people listen.

Silena couldn't charmspeak, but like her sister, she had a powerful voice. This wasn't the first time the two girls had told stories for one of the titans.

As the projector started showing the video, Silena spoke.

"During the early rule of the great king Kronos, a prophecy was heard that the king's children would overthrow him, much like he did to his own father."

"Determined to prevent this," Drew said, "The wise king swallowed each of his children when they were born."

"Queen Rhea wasn't very happy with this," Silena continued. "After allowing five of her children to be swallowed, she decided that she would save the life of her next child."

"Skip that part," Kronos said. "I do not care about my disobedient wife. I want to hear about the defeat of the treacherous gods."

"Skip ahead," Lou Ellen whispered to Beckendorf.

Beckendorf didn't have to be told twice. He typed a different code into it, and a different image was projected from the machine.

"As the gods rose up to fight against the titans," Drew stated. "Kronos unleashed his army against them."

"They fought for many years," Silena said. "The titans' home base was Mount Othrys. The gods' was Mount Olympus."

"When it appeared that the gods would emerge from the war victorious, Kronos created a way to prevent them. The gods fell, and the titans remained in power." Drew and the other three tried to hide their disappointment.

Kronos reclined back into his throne. "Good story, slaves. Now show me what happened after that. Show the punishment forced upon your parents." His golden eyes glinted cruelly. "And this time, let me hear the words spoken then."

Beckendorf frowned as he punched in another code. As a projection came to life, Lou Ellen raised her hand and spoke an incantation; one that would give the images life and allow them to speak out the story they were showing.

Silena and Drew remained quiet, watching the scene playing out in front of them. The scene was set in the throne room. Kronos sat on his throne, and in front of him, the six elder gods were kneeling in front of him, bound by celestial bronze chains.

"You have caused a lot of trouble, my children," Kronos said.

None of the gods replied.

"And now, I see that we must do something with you, but the question is what?"

Again there was no reply.

A faint smiled played across Kronos' face. "That decides it," he said. "You will be imprisoned on Mount Olympus. We will decide what to do with you after that."

The scene flashed off. Silena spoke up.

"The gods were imprisoned, just as the king decreed. Over the years, the titans have put them in charge of certain duties, but they do not escape their prison."

Kronos smirked. "Good story." He looked up at the guards. "I'm done with them. Take them back to their prison."

The four demigods were helplessly pulled away, back to the prison that was their home.

…

Four demigods were gathered around a table, three boys and one girl. One of the boys was busy drawing on a plan of what appeared to be a boat. The other three were busy telling him different things about his drawing.

"Leo, you don't have the angle right on this part of the bow," the girl told the boy drawing.

Leo fixed the angle then turned to the girl. "Thanks Annabeth," he muttered. "Any more helpful tips?"

Annabeth brushed a piece of her blonde hair out of her face. She looked up at Leo and glared at him with her stormy gray eyes. "You asked for my help, Valdez. I'm only doing what you asked."

"This thing is supposed to fly as well as sail, right?" one of the other two boys asked. He had blonde hair and electric, sky blue eyes.

Leo nodded at the boy. "Yep. Or at least I hope it will." He frowned and looked back at his drawing.

"It'll have to," Annabeth said. "If we're going to use it to rescue the slaves, we're going to need it to be as versatile as possible."

"Not to mention that a boat that flies is the only way you're gonna get Jason or Thalia on a boat," the last boy stated, referring to the blonde boy and his sister, who were children of Zeus.

"Ha ha. Very funny, Percy," Jason replied. "And I guess making a boat will be the only way you'll fly?"

Percy flipped some of his black hair out his sea green eyes. "To be honest, I'm still not super excited about the whole flying thing."

Percy was the son of Poseidon, and didn't fly because Zeus hated his guts. Much the same way that Poseidon hated Jason and Thalia, except Zeus was more hateful.

"Hey can we get back to drawing this thing?" Leo asked. He was a son of Hephaestus and he looked like a Hispanic elf. "We need to get it done as soon as possible, right?"

Annabeth nodded. She was about to respond when suddenly two other teens walked into the room. One was a girl with spiky black hair and the same electric sky blue eyes Jason had. She was arguing with the other teen, a tall boy with sandy-blonde hair and blue eyes.

"Luke, you're worrying too much!" the girl shouted.

The four around the table looked up to watch them argue.

"I know what I saw Thalia," Luke retorted. "She's in trouble and I need to help her."

"Who's in trouble?" Leo asked.

Thalia and Luke turned to look at him, and then went back to arguing.

"Luke, I'm sure she'll be fine. We can't risk sending anyone out right now."

"Who are you guys talking about?" Percy asked.

"Nunya!" Luke and Thalia both yelled at him.

Percy backed off and the other two turned back towards each other.

"Thalia, this is my little sister we're talking about," Luke stated. "If it was Jason you'd do the same for him."

"Luke has a little sister?" Percy asked Annabeth.

"He never told me anything about having one," she whispered back.

Thalia was glaring at Luke. "That's not a good point," she muttered. "Jason made his way to camp by himself. I didn't help him. And besides, you told me that you don't even know if she's a demigod or not!"

Luke looked at Thalia with a pained look in his eyes. "It doesn't matter if she is or not. If she is a demigod, then the titans are hunting her because of that. If she isn't, then they're hunting her because of me. Either way, I have to help her."

He started to walk out of the room but Thalia grabbed his arm. She glanced at the other four before addressing them. "Luke's been having weird dreams that his younger sister is in some form of trouble. He wants to go save her."

"You have a sister?" Annabeth asked. "You never told me that Luke."

Luke looked at her. "I did it to protect her. I had to leave her behind when I ran away. I didn't know if she was a demigod or not, and I couldn't risk bringing her if she wasn't. But now I'm sure that the titans are going to hunt her down now."

"So maybe we should try to save her," Leo suggested. "She could be a demigod."

"Only problem is," Thalia said, "Is that she lives in the already reformed world. The titan guard will be super heavy there. There's no way we can get in."

Luke shook his head. "Don't worry about that. I've contacted a few, uh, friends that live close to where she is. They said that they'll make sure she stays safe until we find a way to get there."

"One more question, Luke," Jason said. "What is your sister's name?"

Luke looked at him. "Lex. Lex Castellan."
