A Prophecy

Poseidon doesn't know what to do, and honestly, it started to happen often. Ever since he met Sally, things just went spiraling out of control, and he really didn't care about that. Of course, fun's fun while it lasted, and pretty soon he has to stop seeing her due to the very true fact that he has gotten her pregnant. Oh, the tantrum Zeus would throw at him when he finds out.

And now, he is carrying his only daughter, the first half-blood in centuries after the pact, and could possibly be the source of their destruction. He's not even sure what exactly will Triton and Amphitrite will say about this. All he knew was he has to keep all this a secret if he wants Percy to live. And of course make sure she survives when he actually needs to confess.

He appeared from a green mist into the hall of his palace. Guards consisting of mermans and gnarly sea creatures lined the halls, raising their spears and tridents to honor the sea god. Poseidon didn't feel honored at all, especially since he knew what waited at the end of the hall, or more specifically, who.

"My lord." Delphin bowed respectfully upon his entrance. Poseidon sighed.

"No need for formalities. I have a feeling tonight won't be good." He replied. Delphin merely nodded.

"Queen Amphitrite and Your son Triton awaits you in the meeting hall." He announced.

"I know." he said dryly.

"Good luck." The dolphin swam away as far as he can, a good call with the rage about to happen.

Opening the huge doors, Poseidon stepped inside the hall. The walls were lined with marble columns embedded with corals, seashells and pearls. Typical underwater style you'd find under the sea. Ceilings framed with limestone and abalone fountains glowed from the corners of the room. In the middle of the room lay a huge, smooth marble table engraved with Greek carvings, surrounded by matching chairs with silver and emerald linings. The one at the very end of the table was empty, but beside it two chairs were taken by two mean and grumpy looking merfolk.

Of course, they were none other than Amphitrite and Triton.

Poseidon eased his way to the front, calmly. "Good evening, dear. I presume whatever commotion that happened is taken care of?" He asked innocently, clutching the bundle closer.

Percy squirmed and made a little gurgling noise.

"Oh, I think the meeting is just beginning to start." Amphitrite rose and crossed her hands. Triton glared pointedly at Poseidon. A moment of awkward silence passed for Poseidon, until Amphitrite began speaking again.

"You wish to say something, my lord?" She raised her eyebrows in mock confusion. "Or you would just want to show it?" She motioned towards the bundle.

The Sea god merely sighed, and with a quick glance at his wife and son, he unwrapped the bundle. Percy, big green eyes and a small mop of silky hair stared up at the two. Amphitrite and Triton exchanged glances without saying a word. They stared at Percy pointedly.

"What is this?" Amphitrite waved her hands over the bundle.

"This." Poseidon held Percy tighter."is a half-blood." He finished.

Silence. Nervousness filled the air in the meeting hall.

"Do you realized what you've done?" Amphitrite responded, her voice cold. "This is dangerous. You broke the oath! For all we know, she could already have powers, garnering strength until she grows up, and bring us to oblivion!" She paced, her hands flying around her.

Percy squirmed.

"I know." Poseidon interrupted. "But I can't just leave her above! Can't you see? If she's dangerous, we have to do anything to protect her and make sure she doesn't get corrupted by any of those monsters in disguise. And what better way to do that than to personally take care of her here?" he reasoned. Amphitrite merely shook her head.

"This is ridiculous." She paced around the hall. "I can't believe we're even talking about this!" She stopped and glared at Poseidon. "And you! How could you manage to bring her here! In the palace! Don't you even care about what we think?" her every word was laced with venom, pointed at Poseidon.

The sea god sighed. "I know, I have wronged you." I looked at Amphitrite longingly. "But as her father, would you not want me to protect her? Something's out there and she can't fight on her own." He stepped closer and showed them the baby. Percy blinked and yawned, her eyes starting to close down.

"I'm sorry. I know is wrong on so many ways, but if you wish her away, then I will give it to you." Poseidon wrapped the blanket around Percy tighter, and proceeded to exit the room.

"Come on Percy, I'll take you back on land." Percy reached out her hand and Poseidon grasped it gently. "Then, I'll find you a new daddy." He continued. "And a new mommy." He said and opened the door towards the hall.

"Wait." Amphitrite said.

Poseidon turned around slightly, his hand on the knob. "Yes?" he asked.

"You don't need to find her a new daddy." She sighed. "or a new mommy."

"Why?" Poseidon frowned.

"I'll be her mommy." She decided.

A few hours later, Percy was settled into a sea green crib with seashells dangling above. Poseidon tucked her in as she slept soundly.

"So what do you plan to do now?" Triton asked, looking at his new sister.

"First, we treat her like a family, because she is." He emphasized on is. "Second, we make sure she's safe and sound in the palace. Third, never let your uncles know about her, okay?" Triton nodded his head.

"So, who's her real mom, daddy?" Triton asked.

Poseidon sighed longingly. "A mortal woman, but not just any mortal. A queen among them." He placed a stray hair behind Percy's ear. "And her name was Sally Jackson."

Triton raised his hand and stroke his little sister's forehead. He quickly jerked it away. "Is she supposed to be that cold, dad?" he asked, clutching his hand. Frowning, Poseidon placed his hand on his daughter's forehead.

"We should take her to the infirmary. The snow must've gotten to her." He gently picked up his daughter, who was now sleeping soundly in his arms. Using his powers, he and Triton teleported to the infirmary.

The room was notably empty, with the beds neatly arranged in rows and the cabinets filled with medicines free from any fingerprints. The two medics, a dolphin and a merman, sat idly at the corner. Due to the fact that there hasn't been any war since WWII, they are not really 'in line' with their jobs. Immediately, the two medics swam over the sea god and eyed the bundle he was holding.

"Aye, what is that?" The dolphin chattered nervously.

"Could be one of those baby turtles who lost their shells." The merman replied. Percy opened an eye and looked at the weird duo. She muttered a little 'Aah?' then giggled. Poseidon merely shook his head.

"Where's Nereus?" He asked. The merman and the dolphin shrugged.

"Probably sleepin' at his old caves. The sea folk aren't fond of him." They replied. Clutching the bundle, Poseidon and Triton teleported again.

The city of Atlantis is full of sea life, bursting with the biggest whale to the smallest anemone. Poseidon's palace is found in the middle, it pearls glistens as the sun's rays touch it. The courtyards and gardens were the most beautiful places, surpassing anything you could see on earth. A huge wall made of the strongest stone and thick mist surrounded the whole city, yet the giant double gates made of celestial bronze is wide open.

Outside the city were filled with wild kelp and corals. Stray fishes were found, yet no one would stay outside if it means abandoning a city like Atlantis. At one point, the currents became strong, as if there's a whirlpool in the bottom of the ocean. Poseidon and Triton appeared, not being bothered by the strong currents. A few feet away, seaweed has grown wildly and managed to hide an unsuspecting looking cave. Poseidon slashed the kelp away and stepped inside, followed by Triton.

"Nereus!" He called out. The place was quiet and abandoned, sand dollars and limestone the only things to be seen. Then, at the far end of the cave, a seal, with huge shark-like teeth and oversized flippers came swimming towards the two.

"Poseidon." It hissed, talking to them using deep-sea telepathy. "What brings you in my lonely cave after all this centuries?"

Poseidon stepped forward. "I have something to ask you. I suppose you still have the right knowledge in-" he was cut off by Nereus started sniffing the air.

"What is that?" he gasped. "What did you bring here?"

Confused, the sea god stared at Triton, but he merely raised his empty hands in confusion. Poseidon stared at Nereus, then looked down at the bundle he was holding. Nereus moved closer, sniffing around the baby.

"A half-blood." he suddenly shimmered, green mist evaporating to reveal a man in his 70's, with hair and scruffy beard. "What made you bring that bastard in here?"

Poseidon glared. "I did not bring my daughter here for you to insult her. I rescued her from a snow storm ravaging Manhattan, her birthplace. Now, her temperature is dropping. It must've been the snow affecting her internally. I need your help to heal her." he unwrapped the baby, and Percy yawned, then stared at the Oceanid.

Nereus looked like he was about to protest, but instead he raised his arms, to which Poseidon reluctantly placed Percy. Nereus paced around the room, stroking the baby's hair.

"You do know the consequences of having sired a demigod?" Nereus asked.

Poseidon nodded. "Yes, which is why I would need you to keep this a secret."

The Oceanid shrugged. "I suppose there's no reason to go against you." he decided. "Your baby is fine, yet, I'm sure, not for long." he added.

"What do you mean 'not for long?'" The sea god asked. "What's going to happen to her?"

Nereus looked at them. "The snow storm wasn't just a snow storm. A god like you should know that there are no such thing as 'natural disasters' here. The snow storm was caused by another god." he handed the baby back to Poseidon.

"Who?" He said, anger evident in his voice. "I would personally skewer him with my trident and roast him at the deepest part of hell!" the ocean around the sea god started boiling.

Nereus merely shook his head. "I would not advice you to do that. If you want her existence to remain a secret, it would be best to try not to burst into the ice gods' domain and kill anyone. Besides, nobody knows who exactly did it. Laying low would be the best thing to do, especially if there's a snow deity out there wanting to kill your child." Nereus waved his hand dismissively.

"And what did that god do to her? Why is she cold?" Poseidon gripped his daughter tighter, making her squirm.

"Frozen. The god or goddess wanted to freeze her, but of course whoever it was failed." Nereus slashed at the air and produced a bottle filled with clear liquid. "She only managed to freeze her internally. She is fine outside but not on the inside. But of course, given time, she would still freeze to her death, which is what is happening right now." The old sea god tapped the baby's forehead, which was now as cold as ice. Percy started to cry loudly. Poseidon wrapped the blankets closer and looked at Nereus.

"You have to do something." He pleaded. Triton gripped his father's hand and looked at his sister frantically. Percy skin started to become blue, and a lock of hair turned white. Nereus opened the bottle he was holding, and let three drops of the liquid fall on Percy's head. Immediately, she became warm and her hair and skin turned back to normal. Poseidon and Triton let out a sigh of relief.

"This is not permanent." Nereus warned. "You would need to find a different way to cure her." He raised the bottle, half-full with clear liquid. "Sun's tears. It will momentarily subdue her from freezing, but it cannot heal the cold that has frozen her inside." Nereus tossed the bottle to Poseidon, who took it gratefully.

"Thank you, if there's anything you need, just ask." The sea god nodded at the Oceanid.

"No need for any payment." Nereus said. "The amusement I get when Zeus hears about this is payment enough. And I also have to warn you." Nereus turned back into a seal, and started swimming away. "There will be certain effects caused by the snow inside her. You might wanna look out for that."

The Oceanid swam away, living the sea god and his son looking at Percy as if she might burst to flames under the sea.

"Triton." A whisper came through the sea heir's ears. He grabbed a pillow and covered his ears to block the noise. But it was persistent. "Triton!"

Grumbling, he chucked a pillow at the direction of the voice. "Go away." he growled.

Suddenly, the voice disappeared, leaving Triton in peace. He smiled and snuggled into his pillow, closing his eyes. He managed to momentarily fall into sleep. Then, a crushing weight woke him, like someone was hitting him with a very heavy pillow.

"Ow!" It was in fact, his hyper-active sister jumping on him.

"Triton! Wake up!" She yelled, jumping repeatedly on his bed. Triton grumbled and sat up, weary.

"What is it now?" he whisper-shouted, making sure their parents don't wake up. "It the middle of the night!" he whispered again. Percy smiled and gave him a toothy grin.

"Let's play!" she screamed excitedly. Triton merely rolled his eyes. He looked down at his sister. Percy has grown a lot in the last six years. Her hair was now longer, black and with soft waves like the sea. Her round green eyes were framed with long eyelashes, and her tanned skin the same as his. They, without a doubt, looked alike, Triton sometimes forgot Percy was just his half-sister.

"We can play tomorrow, but right now we should go o sleep." He said and started going snuggling into his pillow again, but Percy whined.

"But tomorrow you'll be gone!" she pouted. Triton felt guilty. He did, in fact, left with their father everyday to train, leaving Percy with Amphitrite. Honestly, Triton would know Percy would be better sword fighting with him and Poseidon rather than talking with other sea deities and tending the garden. He sighed.

"Okay, let's play." Percy squealed happily as Triton slid down his bed.

"Come on! Let's play at the ballroom!" Percy quickly ran outside, her hair flying. Triton followed her.

It has become a habit for Triton to get woken up by Percy every night. He wouldn't admit it, but he actually liked getting woken up by Percy, then being forced to play tag or hide-n-seek in the huge palace. Who knew how quiet and fun the palace can be at dark? The two run down the grand staircase and stopped at the ballroom. It was this huge, circular room with floor-length windows and chandeliers. The moon cast an eerie glow and the sea life outside added the mesmerizing effect. Of course, it all made Percy excited.

"Let's play tag!" she said and took of running, and Triton ran after her. They played a game of 'tag' as always. Percy giggled and screamed every time Triton caught her. Triton merely shrugged when Percy manages to tag him. It was then when Triton was running away and Percy tagged him by grabbing his arm.

"Haha! catch me if you can!" She teased and run outside the ballroom to the hall. Triton ran after her.

"Hey! Come back here!" He yelled and went after her sister, only to be greeted by an empty hall. He looked around, but the palace was so big he couldn't find her. He walked into a hall lined with pillars and a huge fountain spouting water in the middle.

"Percy!" Triton called out. He felt a sharp tap behind him. Turning around, he saw Percy grinning.

"Boo!" She said and ran towards the fountain, giggling. Laughing, Triton ran after her. He could see clearly she was hiding behind the fountain, but he decided to tease her.

"I wonder where she is?" he said as he moved closer. Percy giggled, then Triton jumped and tackled Percy.

"Ha! Got ya!" he yelled. Percy yelped in surprised and pushed Triton away by waving her hand. Then she got up and laughed.

Sticking her tongue out, she said. "Ha! I caught you!" Percy giggled then ran away. Confused, Triton tried to run after her, but he suddenly couldn't feel his legs. He looked down and gasped.

His legs were frozen in a block of ice. He looked up and screamed, "Daddy!"

Poseidon gripped his trident as he marched outside to Nereus' cave. He doesn't usually come to others for help, he didn't needed any for a long time. He was just going to ask a question and he would leave, that's it.

If he would manage to find that snow god that froze his daughter, all hell will break loose. Just thinking of the tortures he could give makes him smile maliciously.

Back to the task at hand, he entered the cave and yelled out, "Nereus!"

The Oceanid immediately appeared in seal form. "We meet again." He bared his fangs in a smile. "And it's only been what? Six years?" Nereus said.

Poseidon frowned. "Nereus, what you did that night-"

"Ah, yes, so the side-effects have kicked in?" he asked, amused.

"She turns water into ice by touching it!" Poseidon said.

Nereus shrugged, turning into a man. "That's better than dying, isn't it? The ice inside her gave her powers, so instead of controlling water, she could control ice." Nereus said. "Don't worry, that's until she freezes solid, which, I suppose, you already found a way to cure permanently?" Poseidon rubbed his temple.

"No, I haven't found a way." The sea god started to pace across the room. "What am I going to do?" he said almost to himself.

"You just have to find something, or someone, that is hot enough." Nereus changed back into a seal. "Something like the sun." he started swimming away, but not before saying, "There's nothing more I can do, but remember, you have to find a way fast. If you don't, the sun's tears will run out, and she will turn into an ice statue right at her eighteenth birthday!"

Poseidon disappeared and teleported back to his palace after hearing the warning.

He pondered for a while, sitting at his throne when Delphin burst inside the throne room.

"Delphin. I asked you not to bother me when I'm at my throne room." Poseidon scolded. The dolphin king shook his head.

"Sir, I have grave news." He said.

"What is it?" Poseidon replied, irritated.

"There has been a new prophecy. A prophecy from the fates!" the servant exclaimed.

"What did it say?" He asked.

"The balance must be restored!" Delphin said. "Two strings tied with a chord."

"What, pray tell, does that mean?" The sea god asked.

"I think it means a marriage sire, some sort of union-"

"A marriage!" Poseidon jumped up from his throne. "Genius! Of course, why haven't I seen this before?" He started to walk around the room.

"Sire, what is it that you plan?" Delphin asked. Poseidon merely smiled mysteriously.

"I think it's time we announce I have a new daughter. That is, to Leto at least." Poseidon smiled and started to stroll out the room.

"Why Leto?" Delphin called out after him. Poseidon turned around, a look of confusion in his face.

"Well, the parents should know first when their children are getting married. Besides, I have to know what kind of family I'm entrusting my daughter to." With that, he closed the door and left, leaving a confused Delphin behind.

A/N: Phew! I'm so glad I finished this! Well, don't forget to review! I accept constructive criticism. If you flame this story, that's fine too.

Remember:

~Triton can choose how old he can be, so he can be a little kid when playing with Percy.

~I honestly feel sorry for Amphitrite and Triton. I mean, they're the original family, but people characterized them as villains or some sort. That is just so...unjustified.

A shorter explanation: Khione wanted to freeze Percy. Turning people to ice statues starts by freezing them on the inside then on the outside. Khione only managed on the inside, but it caused Percy's powers to freeze also, giving her powers over ice. But, the ice inside her will eventually freeze her to death. It can only be cured if she is exposed to something extremely warm.

That's about it. Tell me what you think:)
