A/N: Hey guys. Just wanted to say a little something, before you start reading this story. I have included the characters from the original Percy Jackson and The Olympians series, but I have also added a few O/Cs. Eventhough this is based on Percy Jackson, I have given it my own twist. The story will include a lot of interaction between the Gods and their Kids. And lastly, this is my first ever FanFic, so try not to be too harsh. I'm open to any suggestions anyone may have, and will take as many into consideration as possible. Thanks, and I hope you enjoy.

The Last Guardian Of Olympus.

*FLASHBACK*

"Olivia run!" Yelled the man, as a whip collided with his face, leaving a deep scar on his flushed cheek.

"Dad, I'm not leaving you!" Answered a petite voice. The voice came from a little girl, no older than five or six, as she moved towards the blonde man.

"Honey run, I'll be fine!" He lied, as the tall dark figure who was hovering above him lifted him off the ground, and slammed him against the cold concrete repeatedly.

"DADDY!" The little girl screamed, as one gigantic hand grabbed her by the shoulder and pinned her against the ground, and the other pressed her face against the rough surface of the earth, facing the monster with her father in his grip.

"Now watch your daddy's last moments, child..." whispeared a cold, deep voice, which sent a shiver down Olivia's back.

A tear rolled down the girl's cheek, as the tall dark figure stabbed her father, Michael Anderson, tirelessly. The screams shot through her like bullets, it was her worst nightmare come true. She tightly scrunched her eyes together, when she heard a heartless laugh. Then the pressure which was pressing down hard on her head and shoulder dissappeared. As olivia opened her eyes she met a gruesome sight, her father, lifelessly lying on the ground. His once joyful smiled transformed into an emotionless line. His once crismon cheeks replaced with a blanched colour. His once warm, blue eyes substituted with chorcoal irises. He was gone. Olivia dashed towards the empty corpse, sobbing. She hugged the body begging for her father to be returned, but it was no use.

*End of Flashback*

Olivia gasped for air as she lifted herself up from her bed. Cold sweat crawling down her body. That memory still haunted her today, ten years after the incident. The helpless screams rang in her ears. She wanted it to go away, to never come back. So that she dind't have to remember-So she didn't have to blame herself for his death. Olivia knew she was the reason for his death, but deep down, she was aware that she couldn't have done anything to stop it, after all, she was only a child back then.

The now 15-year old stood up, fully waking up and becoming aware of her surroundings. She was in her own cabin, as she expected, she moved towards the bathroom in swift motions. As she washed her face, which gave her a feeling of refreshment, Olivia heard a knock on her door.

"Ollie, get out! Do you know what time it is? You're missing breakfast!" She knew that voice all too well, Oliver, her best, and only friend. She wasn't very popular, she was unknown, only the closest to her knew anything about her, to the rest, she was invisible. The truth was, she didn't know of the time. Her eyes widened in disbelief, after she glanced at her alarm clock. 9.30am. She was late for breakfast! Never in her life, has she been late for anything-well apart from one or two occasions, but she did have a reasonable explanation for both-especially not breakfast. She sprung around her room,after finishing brushing her teeth, placing on pieces of clothing; denim shorts, with her orange camp half-blood shirt,a grey hoodie and some converse. She didn't particulary like the camp shirt, but it was the first thing she found.

"OLIVIA!" She once again heard the voice.

"Okay, Okay, I'm coming! The canteen isn't going anywhere." She shouted back.

"For Styx's sake! But the food is!" When she was finally ready she walked out, to meet a warm, bright smile which belonged to Oliver.

"Hey! Finally Ms. Sleepy head decides to show up!" He said in a deep, yet soft musical voice. The son of Apollo. He was tanned, with blue eyes and blonde hair with dirty blonde highlights. He was awfully cheerful today, not that he wasn't on a normal day, but today he couldn't stop smiling. Olivia knew something was happening, otherwise he wouldn't have been so impatient.

"Oi!" She simply replied, hitting him on his shoulder. He laughed at the gesture.

The two headed off to the canteen area of the camp. They were surprised to see a large crowd around the entrance of the camp, just before the dining area.

"Come on" Said oliver, grabbing his best friend's hand and dragging it along as he ran towards the centre of the circle. Olivia didn't even realise that she was moving, as a thousand thoughts dashed through her mind. What is happening? Who could have caused such a crowd? Why are they here? Where are they from? This was the usual for her, always thinking, her mind at ten different places at once. It wasn't something she could control, it was like a reflex.

As Oliver and Olivia reached their destination, after a couple of dirty looks from the other campers, after Oliver quite rudely shoved them aside-which was unusual for him, they finally saw them. Percy Jackson, Annabeth Chase, Clarrise La Rue, Nico Di Angelo and Thalia Grace. The legends of Camp Half-Blood.

"Woah..." Oliver managed to whisper, when a shocked yet excited expression crossed his tanned face.

Olivia gave him an awkward look as an answer to his last comment. Yes, she knew who they were, but it didn't really bother her. They may have been heroes, but she never knew them, not that she wanted to, yet something deep at her core told her that she should find out why they were at the camp, and what they wanted. She often got that feeling, like a concience, but she didnt believe she had one. Glancing around all the campers, olivia spotted Chiron, and leaving Oliver to his day-dream, she carefully moved toward the centaur, trying not to bump into anyone. After she got out of the crowded gathering of Half-Bloods, she strolled towards the half-man, half-horse creature. He was also gazing at the old campers, who have now moved on in life in the real world, with some having started families, and others slowly also reaching that stage.

"What are they doing here?" She asked, not exactly making eye-contact, following chiron's gaze to Percy and his gang who stood proudly smiling at the rest of the camp.

"They're here on a visit. They decided to take a break from their everyday lives to come visit you all here at camp." He replied, looking over at the teenage girl, who was studying each and every one of the elder campers, narrowing her eyes, and then opening them wider again after she answered her own questions, silently in her head. Yet he knew that she was listening, she always did. It was a useful trait of hers, being able to listen to people while being lost in her own thoughts.

"Why?" She questioned, finally looking over at Chiron with a confused expression.

"Mr D and I invited them. We thought it might be a good idea to let them share their stories." He announced to her.

She slowly exmined his face. A moment of silence filled the air between them, until she finally spoke.

"By 'Mr D and I' you mean you did. So that they can share their stories with us, and cause upset among the campers that had not yet been on a quest, and the others whom have not yet been claimed." She responded, shaking her head, scanning the ground and then back at the centaur's face, before turning to and over looking the crowd.

A sad image formed on his face. He sighed deeply, however not in an annoyed manner, but in a kind one. He rested his chin on his staff, and peeked at the young camper, who had a sadened look on her face, gazing at the five visitors who were answering the questions of the current residents of the camp.

"And by 'others who have not yet been claimed' you mean yourself." He exclaimed.

"Yes, I do, seeing as I am the only one who hasn't. Nine years I have lost here, for no sapient reason. Travelled far, to accomplish quests, on their will, like a puppet, yet they still think I don't deserve to know the truth" She sighed, placing her hands in the pockets of her shorts, and looking down. After receiving no reply from Chiron she added, "But it doesn't matter. Don't let it trouble you, go enjoy the company of your favourite students." And with that, she patted him on the back, twisting on her heels, and walking off.

With no further or do, the centaur considered to take action on the idea, at last, trying to seperate the crowd so that he could talk to the guests.
