A/N: The Son of Neptune takes place six months after The Lost Hero. Please stop telling me they happen one after the other, because they don't. This story is Percy being sent to the Grand Line during those six (in my world, eight) months instead of kept asleep by Hera.

A/N: I dedicate this chapter to my flame guest reviewers: Max, Kane and Leon, who even though I am clearly not done yet, have seen fit to call my work garbage, crap, and insist that I delete it because it doesn't follow their version of the PJ OP timelines. I don't know who taught you that it's ok to to talk to strangers that way, but this one's for you.

"And you just found him by the black smokers?"(1)

"Yes, your highnesses. He seems to have fallen from Sabaody, though he is uninjured."

"Send our brother to Shirahoshi; she can look after him until he wakes."

"Are you sure, brother? We all felt those tremors; it is clear who caused them."

"Perseus is our brother; we have to help him. The rest of the island mustn't know about him."

"Agreed; they'd tear him apart."

"Which is why he will stay here until he has recovered."

"In the mean time, we'll figure out what to tell him about Marineford."

O.N.E. P.I.E.C.E

"So you're Zoro, huh?"

"Are you hard of hearing? I already introduced myself earlier."

Fire Fist Ace slung an arm around Zoro's shoulder, "You know, in all the yammering I've heard in the past day about Luffy's crew, you're the one he yammers the most about."

Zoro's face felt hot and Ace laughed.

"Just make him happy, ok?"

The gloom sort of woke Zoro first.

It wasn't enough to really wake him up, but the damp air was making his skin itch.

It was Mihawk looming over him that really woke him up.

"You beat the baboons," said the World's Greatest Swordsman.

Zoro felt like an iron rod was twisting his organs, but he still staggered to his feet to face his rival, "I beat the baboons."

"You don't still want to leave?"

Ace's bloodied corpse, forever memorialized in black and white.

Luffy, praying at Marineford.

"No."

"Very well," said Mihawk, "Then I will train you."

"5,000!"

"Eto, Usopp-un," said Heracles, "It is admirable that you want to lose all this weight, but you're going to get a cramp-,"

Usopp howled in pain and dropped from his tree branch.

"I can't stop," he tried to make the armored beetle understand, "I can't let Luffy down again! Not ever! I've only got 2 years to make good on that promise!"

O.N.E. P.I.E.C.E.

Robin stumbled over an icy train track.

"Here."

"Thanks," Robin gratefully accepted the coat, "What did you say your name was?"

A blond haired man, maybe a few years older than Luffy, gave her a toothy grin, "Sabo. Nice to meet you, Nico Robin. Welcome to the Revolutionaries."

O.N.E. P.I.E.C.E.

"Again!"

Last night, Luffy dreamed about Ace.

"Again!"

Ace, smiling bravely with Akainu's burning fist sticking out of his bloody chest cavity.

"Again!"

Ace, crying as he died.

"Look, Luffy, you're still healing," Rayleigh said hesitantly, "It's ok to take a break-,"

Ace, thanking Luffy for loving him.

"Again!"

O.N.E. P.I.E.C.E.

His body burned in the fall.

'Bang!' 'Bong!'

Vegapunk's laboratory was too cold for Franky to notice the burns.

'Clank!' 'Clang!'

His technology was useless.

'Bang!' 'Bong!'

It didn't save Luffy.

'Clank!' 'Clang!'

It didn't save Zoro.

'Bang!' 'Bong!'

It sure as hell didn't save Percy.

'Clank!' 'Clang!'

And it didn't save a brother that Franky never got the honor of meeting.

'Bang!' 'Bong!'

Fine.

'Clank!' 'Clang!'

If his body wasn't good enough to save his friends, then he'd just make a new one.

O.N.E. P.I.E.C.E.

Gather up all of the crew it's time to ship out Binks' Brew

Brook, for the first time in his life, was singing flat.

"Not really up to your usual standards."

Brook turned around. The Longarm Tribe was gone behind a funnel of fog.

Kami, Brook hated fog.

"It's not fog, Brook," a woman in a black robe emerged from the fog in front of him.

No-she was behind him.

No, that was wrong too; she was to the east.

No, she was everywhere. Four identical women stood around him, each holding twin bronze torches.

"Who are you?" Brook asked warily.

The woman looked beautiful in the firelight, with dark, clever eyes and a long, regal face.

"You're a user of one of my Devil Fruits, aren't you?" asked the woman.

Brook's eye holes went wide, "You mean-you created the Devil Fruits? The world's biggest mystery? I can't believe my ears."

"If I had any, Yohohohoho," Brook laughed half-heartedly.

The woman bared her teeth in something akin to a smile, "Pleased to meet you, Brook, user of the Revi-Revi fruit. I am Hecate, Goddess of Magic. You and your crew intrigue me, so I am going to show you how to use your Devil Fruit to harness the power of the Mist."

O.N.E. P.I.E.C.E.

Chopper was a monster.

He'd really messed up this time, and because he lost control, he got booted all the way to the South Blue.

Now, Ace was dead.

Percy, for all he knew, was also dead or rotting away in Impel Down, and the rest of his crew was scattered around the world.

And Luffy...that scar on his chest looked terrible, even in newspaper form.

And Chopper wasn't there to heal it.

But here, in this library with Shanba, Chopper began to feel a sliver of hope. The well of information at his disposal was incredible. With this he really had a chance to become the kind of doctor who never lets his crew get injured and die again.

As for Chopper himself? Maybe, just maybe, he could learn how to really control his powers.

After all, if being a monster meant that he could protect his friends, then Chopper could learn to live with being a monster.

O.N.E. P.I.E.C.E.

"Come on, I beat Caroline," Sanji growled, "Now give me the damn recipe!"
"Sanji-chan, deary," Ivan said, sounding more serious than she had the entire time that Sanji had been stuck in this fluffy, pink hell, "Maybe you should sit down."

"If this is about Luffy, I don't want to hear it," said Sanji, "There's no use wasting time thinking about Ace, anymore; I'll be there for Luffy when I see him again in 2 years."

Ivan bit her lip, smudging her favorite, red lipstick, "It's not that. I've received word from Dragon."
"Oh?" said Sanji, sounding hopeful, "Is it about Robin? Has she liberated a country, or something?"

"No," said Ivan, "Your father knows you're alive. He's looking for you."

O.N.E. P.I.E.C.E.

Nami stumbled and dropped her armful of books.

"Ow," she grumbled, fishing Weather 101 out of a cloud, "That Haredas is a real hardass of a teacher."

She giggled at her pun, "He better know what he's doing; I've got to be the best navigator I can be when we reunite in 2 years."

"Are you Nami?"

Nami finished picking up her books and turned around to find a girl no older than her, in pale blue robes, looking at her with big, green eyes.

"Who wants to know?" Nami asked suspiciously, "I thought everyone here was an old wizard man."
The girl rolled her eyes, "I'm clearly not from here, silly."

"Then where are you from?" asked Nami, "And who are you? And how do you know my name?"

The girl took a big, shaky breath, "Right, well, you see-,"

"Spit it out already!" Nami snapped. Those books were very heavy; Nami was eager to go put them away.

The girl steeled her face, "My name is Selina Beauregard, daughter of Aphrodite. I recently came back from the dead, and our mom sent me here to find you."

Nami dropped her books again.

"Percy wasn't joking," she said faintly, sinking to the sidewalk, "I really do have siblings."

Selina's eyes widened, "You know Percy Jackson?"

"Yeah, he's part of my crew," she told her new sister, "He showed up out of nowhere on our ship a few weeks ago, he'd been sailing with us ever since."

Selina pulled her dark, wavy hair back into a ponytail and began picking up Nami's books.

"I understand now," she told Nami, "Why I'm here."

"Ok, I'll bite," said Nami, "Why are you here?"

"Gaea is waking," said Selina, "The Doors of Death are open. Mom guided me here to prepare you for war."

A/N: As some of you might've noticed, I update really fast. This is because by the time I started uploading this to the website, I'd already written a good chunk of it. I've been at least five chapters ahead this whole time. I think I'm going to take a break from writing for a little bit. I'll keep uploading until I've run out of chapters, but for my mental health and the quality of my work here and in my real world job, I need a few days to myself. I hope you'll understand.
