At first the three loved each other. Then, slow as it was, two of them became further apart from the first born. Soon, the eldest vanished without a trace. The eldest only returned when his family is in need, but will the eldest help them?

Prologue

A mysterious man with red eyes that looked like rubies with a rim of gold and short, messy black hair watched a group of demigods in Maine from afar.

Looming above him was a castle. It looked eerie in the darkness of the night sky. It seemed to come from nothing, showing no light at all.

The man sat atop a horse. He was clad in black and his horse was also black. His horse had a midnight black mane, and the same color for it's hide. It only showed in the night because of the glow of the moon. It showed lots of knowledge in the horse, and it contained lots of power. On it's back was a silvery black saddle with red outlining.

He looked through the trees, studying a battle that was going on. The Hunters of Artemis, a satyr, and three campers were battling the manticore. Two other children sat cowering behind a tree, probably inexperienced.

The manticore lunged at a woman with auburn hair that looked around twelve. The man shot a blue arrow from his bow, turning the manticore into golden dust.

"Show yourself." The goddess and her Hunters pointed their bows in the direction of where the arrow came from.

The horse trotted out of the forest line. Artemis promptly gasped as she saw the man, staring at him in shock.

"Hello, little sister," said the man, but he wasn't being annoying like Apollo would. She was actually his little sister. He was the first child, she was the second, and Apollo was the third.

"Percy?" Artemis asked, letting off some of her shock. She stood as stiff as the trees in front of her. Her fingers twitched slightly, and she dropped her bow.

The man's eyes shown with barely contained anger. "Nice to know you recognize me, Artemis," he said, a scowl on his face. He slid off of the horse.

"Where have you been these past millennia?" she asked him, losing the shock. She closed her eyes slowly. This had to be a dream. He was supposed to be on Delos. He was supposed to be on Delos. The more she told herself it, the more she believed it. But when she opened her eyes, he was still there. And he looked way different than he did before, but people change after three thousand two hundred twenty three years, right?

"Why would you care?" Percy demanded, his scowl deepening. "You and Apollo are the reasons I disappeared. Had me sent to the Hell-Pit, and then to Delos. At least I had my mother anyway."

"Who is he, milady?" asked a girl with silver circlet in hair. She had caramel colored skin; long, silky black hair braided with the circlet in it; and volcanic black eyes that stared at him in distrust. She stood beside Artemis, and her bow was pointed at him. "He doesn't seem like Apollo."

"My brother, Perseus," Artemis said, on the verge of crying. He glared at her for calling him his Roman name. "H-ho-how did you get out? And w-when?"

Percy waved her off and turned to the campers. There were three girls. One of them was a daughter of Zeus. She had electric blue eyes, short, spiky black hair, and freckles on her nose. She wore punk clothes like a shirt that said Death to Barbie.

Another was a daughter of Athena. She had stormy grey eyes that gleamed with wisdom and short blonde curls that made her look like a princess. She wore casual clothes that were a little dirty from the manticore encounter.

The third was a daughter of Poseidon. She had bright sea green eyes that glinted in the moonlight and long, messy jet black hair. She wore a Camp Half-Blood T-shirt, blue jeans, and Nike Foamposite Ones. She had a kind of light in her eyes that showed you could trust her.

"Hello, demigods," Percy said, his eyes twinkling with mirth at the fear on their faces. He smiled. "I won't hurt you, though I can't say the same for them." He pointed at the Hunters.

He caught the eyes of one of the people in the back. "Ah, Phoebe," he said, and his smiled grew ever so slightly. "Remember me? Well, it would be a miracle if you did remember me from that long ago."

Phoebe was a dryad. She didn't look like other dryad, nor did she look like a hamadryad. She had rich blue eyes that changed colors in the sunlight; she had long dirty blonde hair that reached her waist. She wore a silver parka with dark camo pants.

Phoebe nodded. "You…" She halted for a second, trying to remember. Her eyes brightened even more as it clicked. "You always came with us on hunts, before, you know. You mostly used your sword, Πόλεμος-Πλαστά Κηδεμόνας, I think it was called, but you wielded a spear called Ακίδα του Χρόνου. You also had a bow called φάντασμα."

He nodded, and his eyes showed elation. "Yes, yes. So, you do remember me," Percy said, putting his hands together. His eyes gained a mischievous glint.

"Well, you see, Phantom has a title, right?" he told them, smirking a little. "The title is what gives Phantom it's meaning."

He shot an arrow. It flew by a Hunter's ear and flew off the cliff. It flew around like a cropduster, and it made the words 'Oath of the Lasting Night' in cursive. Then, beside it, a phantom was drawn. It was of a small girl that Percy had tried to save from a burning, and her death haunted him for years.

The demigods took a step back from the cliff, startled from the ghost.

Percy smiled when he saw it. "That is my symbol."

"Well, see you, Arty," he said, and she turned towards him with a red face. "Ask Apollo for a prophecy about the Night." He placed two fingers to his forehead and saluted. He slipped into his horse and they ran off the cliff.

Percy waved at them and he disappeared, as did the phantom and the title of his sword.

Children of the Sky and Motherhood,

Shall reach Knighthood,

Together to save thy sister,

And make a twister,

For blood runs cold,

And eldest brings the downfall of the king of old,

At the time of night.

Percy sat cross-legged with Artemis laying on his shoulder, her eyes closed and her breathing steady. Apollo sat beside Percy, drawing figures in the dirt. Many of them were fight scenes, and they came from the things he saw in his dreams.

"Where's Mommy?" Apollo abruptly asked, looking around the area. The house door was ajar and light came through the side window. Two figures conversed at the wooden table they had in their kitchen.

"She's talking with someone," Percy said, hoisting Artemis' sleeping form onto his shoulder. He looked up into the night sky. The moon was about halfway across the sky. "Let's get to sleep."

He and Apollo walked into the house quietly, and went down the hall. Apollo went in his and Percy's room, while Percy placed Artemis on her bed, tucking her in. He kissed her on the forehead, and slipped out.

He made a split second decision and crept toward the kitchen. He could hear voices, and they both were feminine. One held more power than the other.

"Leto, you must let me take them, it's only for the best," someone said, and their voice sounded tranquil. She sounded like she didn't have a care in the world, but she spoke in a monotone.

"No, I will not give any if my children to you!" Leto snapped, her voice going higher than he had heard her tone ever go. She was usually kind, no matter to who it was, and no matter what the triplets did. "What's it to you, anyway?"

Percy peeped around the corner. The woman stood in a prideful way, showing she thought she was above everyone. She had stunning, yet scary, gray eyes that glowed with knowledge; she had what looked to be long black hair, but it was tied back in a ponytail, so you couldn't really tell. She wore a grayish blue peplos. (That's what women wore in Ancient Greece.)

The woman looked taken aback, and looked surprised beyond. She quickly regained her composure. "Because he is my brother," she said, showing the first bit of emotion. She searched Leto's face, and was obviously satisfied with what she saw.

Sister? the first son of Leto thought. His mother had told him he had other sisters that came from his father's side of the family. He resented Zeus a bit, though.

First and foremost, there was the fact that he started to cheat on his wife and sister, Hera, the goddess of marriage. He understood that she would get a little bitter from having constant reminders of her husband's adultery.

Secondly, there was the fact that he couldn't keep it in his pants. There were probably many demigod children that Zeus had.

Percy moved his foot, and the floor creaked. Crrrreeeaaakkk. He froze. He didn't move his body, and he could barely hear his heartbeat, that we how shocked he was. The woman slowly walked toward him. His mind was screaming at him: GO! but he couldn't move a muscle.

She placed a hand on his shoulder and gingerly turned him around. She pulled him out of the light and he saw Leto scowl.

She narrowed her eyes slightly. "Were you eavesdropping, Perseus?" his mother asked, looking him directly in his orbs. He cringed; she never called him Perseus unless he was in serious trouble, like when he and Artemis had gotten in a fight. He prayed that he wouldn't be in that much trouble, but luck may not be on his side.

"Sorry, Mommy," he said, looking down at the ground. He sighed sorrowfully.

She smiled. "Well, you can stay for now," she told him, letting out a breath. "But soon you'll have to sleep."

The woman sat down at the table. She put her hands on top of it and a book materialized. "I am Athena," she introduced, extending her left hand toward him. "Your sister."

He hesitantly walked toward her, and his mother nodded at him. He, though still a bit hesitant, walked over to her at a quicker pace. He shook her hands slowly, and she smiled.

"Nice to meet you… Athena," Percy said, returning her smile. He let go of her hand and sat down in a chair between Athena and Leto.

Athena opened her book, and Leto's shoulders slumped. "I would like to ask you something." She paused, and he nodded for her to continue. "I would like you to come with me, so I can train you."

He was flabbergasted. "Me?" he asked, and his eyes widened. He looked at her, and she nodded. "But what about Apollo and Artemis? Do I have to leave them?"

She signed sadly. "I wish we could avoid it, but you must come without them. You have to be able to protect them later," Athena urged, turning the pages in her book.

She flipped to page 124 and read it. "'A choice to be made by a fierce warrior, and the god of time follows the path. He makes an oath for centuries, but breaks it for a love greater than life. He gains the domain of night, and brings on new ways.'"

"I don't want to leave my siblings," he stated, crossing his arms in front of him. "I am going to stay with my family."

Athena gained an angry look. She shook her head and slammed her book closed.

"Athena! You will not treat my son as if he is a mere pet!" Leto yelled, her eyes boring into Athena's head. The goddess of wisdom flinched despite herself. "Get off of my island!"

Athena picked up her book and glared at the Titaness of demurity. "You will pay for this, Titan." And with that, the Olympian flashed out.

Leto turned toward her son. "I think it is time for us to retire, Percy," she said, standing up. She kissed him on the forehead. "Good night, son."

Okay, guys. That is it for this chapter. Hope you guys like this story, and I will update as soon as possible. Tell me your thoughts on what this should be and constructive criticism is appreciated. Please point out any mistakes I have made and I will fix it as quickly as possible.

The prophecy earlier, from what I gather, will happen soon. Not in the next the chapters, but it will happen in the future. Hopefully.

Just so you know, what Athena read, under any circumstances, is not a prophecy, so it needs not rhyme. It is merely a telling of the future. You will find out how Athena knows later on, but for now…

—MS.R

Peace!
