Percy

After about thirty seconds of awkward silence, Annabeth broke the tension. "Well, it seems that either you all have the same mother, or Poseidon has some explaining to do." Percy felt embarrassed and averted his girlfriend's gaze. "Oh jeez Percy, that was mean. I shouldn't joke about this."

"It's fine," he lied. "I think I'm gonna have to have a little talk with my dad, though."

"Of course, but it's getting late." Chiron insisted. "I suggest you all get some sleep. I have a feeling tomorrow is going to be very eventful. Percy, take your siblings to the Poseidon cabin. Annabeth, I would like to speak to you in private."

Percy knew that he was being kept out of the loop, and he hated it, but there was no use arguing. He said goodnight to Annabeth and Chiron and lead his brother and sisters out of the Big House and towards cabin three. On the way, Dylan stopped and pulled Percy aside. The girls stopped as well and turned around, confused. "It's the second-to-last one on the left. I'll be there in a minute." Percy assured them. They still looked a little nervous, but they continued towards the cabin.

Once they were out of earshot, Dylan looked apologetically at Percy and said, "Look, I'm sorry I hit on your girlfriend back there. I don't know what came over me."

"What do you mean?" Percy asked.

"I'm not really sure, but it felt more like I was spectating than participating. Almost like…" Dylan looked distracted all of sudden.

"Dylan," Percy waved his hand in front of his brother's face "what were you about to say."

He looked puzzled. "That's funny," he said "I can't remember anymore."

Still a little bit bothered by what just happened, Percy changed the subject, "Well, apology accepted. It took guts to approach me. I thought I was gonna have to tell you off."

"Thanks. I still feel like a jerk, though. I just hope that she doesn't hate me now." Dylan looked upset as he said this.

"Annabeth? Nah. She'll get over it. I'll make sure she knows how sorry you are." Percy assured him.

"Thanks," he sounded relieved

"Wait, were you scared of my girlfriend?" Percy asked suspiciously.

As his cheeks grew pink, Dylan answered "Umm, kinda. Those grey peepers of hers freak me out a little."

"Polite and smart?" Percy laughed. "Relax, Dylan. I'd be worried if she didn't intimidate you. And personally, I don't blame you. Don't tell her I said this, but her eyes still kinda freak me out, and I've known her for three and a half years. Anyway, we should get going. Your sisters are almost there."

And with that, they jogged toward cabin three and arrived at the entrance at the same time as the girls. Percy held the door for his three new roommates and announced, "Welcome to Casa de Percy. You can sleep wherever you want. I sleep on the bottom of the middle bunk on the left. The bathrooms are across the courtyard and behind the even numbered goddess cabins. I'll get you some clothes and toiletries from the camp store tomorrow."

After they had all gotten settled in, Percy fell asleep quickly. Unfortunately, as soon as his eyes closed, his dream began.

Percy found himself in his father's underwater palace, kneeling before Poseidon and his wife, Amphitrite.

"Father. Lady Amphitrite." He bowed his head.

"Son," Poseidon said, "there is much we need to discuss. However, we have little time. Someth—I mean, someone else seeks an audience with you."

Percy realized that Poseidon was hiding something from him. "Who?" he asked suspiciously.

"You will see soon enough. First however, I must apologize for not giving you a heads up before your new siblings arrived, but I didn't know I'd be sending them this soon. And don't worry; you weren't actually born on the same day, well, at least, not exactly."

"It's okay, I'm actually starting to get used to the idea," Percy admitted "But could you elaborate on the 'sending them this soon' and 'not exactly' parts?"

Poseidon smiled a bit, obviously relieved that his son was so forgiving. "Well, like your friend Nico di Angelo, Dylan, Meredith, and Morgan Irvine were born just a few years before World War II. And the fact that they have the same birthday is due to my habit of taking shore leave in October and November."

At this, Amphitrite glared angrily at her husband, and Percy saved him with "So you sent them to the Lotus Casino for what, like 70 years?"

Poseidon gave Percy a grateful look and then said "No. I kept them in a sort of deep sleep in my palace. Not just to protect them, but also because Apollo's oracle gave me a prophecy that warned me that I would need them in the future."

"So that's why they just walked out of the ocean. But if you sent them, how did they not already know that you are their dad?"

"I used the mist to give them fake memories." Poseidon stated flatly. "I took pity on them, so I let them experience a regular life in their minds."

Feeling a little awkward, Percy changed the subject with "What did the Oracle say you would need them for?"

Poseidon's face went pale. "You must go now Percy. The answer will present itself shortly. And remember, your siblings are not only three but also one, like my trident. Goodbye, my son."

And with that mystery fresh in his mind, Percy was thrust out of his father's throne room and into the ocean. When he stopped, he was standing over a huge crevice at the bottom of the ocean. For some reason, he knew that it was the Mariana Trench in the western Pacific. A deep gurgling sound resonated from every direction. A chill went down Percy's spine as he realized that it was laughter.

"Foolish demigod," the voice said "There is no hope! You have no idea what is to come; the hell that your life shall become if you oppose me. Join me, however, and I shall make you my lieutenant and spare the lives of those you care about.

Percy wanted to run, but he couldn't move. "Who are you?" he asked, fear evident in his voice.

"If you have not already guessed," the voice boomed "then I am wasting my time. I have no need for ignorant buffoons. You shall be destroyed with the rest of your puny friends, and this world shall belong once again to the Sea! Be warned Perseus Jackson, resistance is futile! (A/N: Borgs!) You cannot defeat me, for I am Pontus, Primordial of the Ocean!"

With that, a deafening growl came from the trench. Percy was pushed closer to the pit by an invisible force. As he peered over the edge, a yellow eye the size of a football field opened and something huge and scaly shot out of the trench and enveloped Percy. This was not the owner of the voice, Pontus. No this was something much, much worse. The thing gradually tightened its grip as it pulled Percy into the trench and toward its giant maw.
