On another note; There will be a bunch of alternate realities and I'd love to hear some suggestions from you what alternations you'd be interested in.

I've divided the character list and the pairing list into the different worlds they'd visit as to not confuse anyone, because there will be more than one Percy and stuff.

Oh and, as always, I take my liberties with Nico and with the characters' last names in some cases.

All the Percybilities

Meeting Your Other Self

Prologue: The Offer of Chaos

Nico di Angelo felt like shit.

His head buzzed with noises and it was hard for him to tell which ones were real from the outside world and which ones were only inside his head. There was a certain aching all over his body. Groaning in pain he blinked a few times. The pain was all over him, but there was an odd dullness in his left arm and that kind of really freaked him out. Though it eased and confused him at the same time to see what caused the dullness. Black, messy hair sticking in every direction, framing a beautiful face with eyelids hiding what Nico knew were the most unique sea-green eyes.

Percy Jackson was laying next to him on the bed, abusing his arm as a pillow.

The first thought that crossed his head was: This must be some strange kind of alternate reality. Or a very good dream. Nonetheless he decided to enjoy it as long as it lasted. A small smile tugged on his lips and he turned a bit so he could take a better look at the peaceful face of the boy he had been secretly in love with for years now.

"You're awake, Nico", whispered a voice he distantly remembered.

Lifting his gaze some, he saw a blonde guy standing in the doorway.

"Will... can you tell me what the Tartarus had happened?", murmured Nico with a yawn.

The son of Apollo smiled at him and came some nearer.

"You got yourself abducted by a very old and very evil woman, but I guess you know that part", whispered Will, checking on Nico. "We came to rescue you with the Argo II after we've finally finished it. We went to the Roman camp first, collecting Percy, a guy named Frank, Jason's girlfriend Reyna and your sister of whom you haven't told anyone anything. Just wait for Leo, he's really angry at you, you know? There's also a bunch of angry looking Romans who try to keep to themselves and away from us wicked Greeks and a bunch of odd girls talking about orange jump-suits and iron-collars. They really freak me out. Anyway, we went to rescue your sorry ass and look, we did it. We're on our way to Greece at the moment. You're not all that badly injured, but a certain someone demanded to stay at your side until you'll wake up."

"How are the others?", asked the son of Hades slightly concerned.

"Leo's fine. A bit brooding though. Jason is so busy sucking faces with his girlfriend now that they're finally together again, I guess he wouldn't have noticed if he'd lost a leg. As you may have seen if you'd have eyes for something else aside from Percy, you would have noticed that you're not the only one in the room. Annabeth got hit pretty badly."

Dark brown eyes widened in fear as his head whirled around to stare at the bed next to his. True to Will's words there was a sleeping blonde laying in the bed, a native American girl sitting next to it with her head rested on the mattress.

"Piper didn't leave her girlfriend's side either", sighed Will. "Even though I told her to take some rest herself. She charmspeaked so many evil guys that she was too exhausted to even walk upright anymore once we were finally through with this fight."

"But they're okay? It's nothing too serious?", wanted the Ghost Prince to know.

"No. Frankly enough, we had no losses and no real big injuries this time. Clarisse, this Frank and Annabeth really did a great job with the strategy. Everything is alright, mostly I guess."

"Are they awake yet? Are they alright?", called the loud voice of the boy Nico had befriended in the course of the past few months.

Leo Valdez barked into the cabin with all his loudness, closely followed by the two siblings he was closest to. Jake and Nyssa were both looking greatly annoyed as if they had tried their best to hold their younger sibling back. But knowing Leo's fierce temper they had obviously no chance.

"Shut up, Valdez", hissed Nico irritated. "Don't you dare waking Percy up!"

"Oh, shut up yourself, di Angelo", grunted the head of cabin nine and walked up to the son of Hades to hit his upper arm. "Why didn't you tell me about your little sister?"

The half-Italian rolled his eyes. In the past months since Percy's disappearance and the appearance of Jason, Piper and Leo, there had been some changes at camp. It soon became rather obvious to the newly arrived trio that Annabeth wasn't the only one desperately searching for Percy Jackson once they met the son of Hades for the first time. After Jason remembered his past and especially so Reyna, it also became undeniable that there was no chance for Piper and him to truly work. She and Annabeth had found comfort in each other. Though that had angered Nico beyond belief. Annabeth was supposed to be the happiest girl in camp, she was after all lucky enough to be Percy Jackson's girlfriend. The blonde had broken down though, crying in his arms, telling him that Percy was her best friend and certainly one of the most important people in her life, but not the love of his life. She had confessed that Percy was more of a rebound after Luke had died, loosing the first love of her life had confused and upset her and Percy had helped her over it. But Piper woke feelings within her, feelings she hadn't known in a long time. Nico all the while found a very good friend in one cheeky son of Hephaestus.

"Because I didn't want you to hit on her", smirked Nico and winked at the other boy.

"Dumbass", grinned Leo and hit his friend's upper arm again.

"Would you two tune it done some?", moaned a tired voice next to the son of Hades.

The two boys turned to the sleepy son of Poseidon next to Nico. Percy yawned and stretched some.

"Percy! How are you feeling? Are you alright?", asked the Ghost Prince concerned.

"I'm the one being okay", grunted the green-eyed teen. "You're the injured one. How are you? You've been unconscious when we got you... I... I've been worried to death..."

Percy averted his eyes, staring down at his lap. He truly had been worried. When they had reached the captured half-blood it looked as if the teen was dead. That was probably the biggest scare he had had in his whole life. A hand on his arm brought him back to the present.

"I'm alright, Perce. Really", smiled the son of Hades softly.

"Oh, good", smiled Percy back, before raising his hand and slapping Nico hard.

"Ow!", grunted the Ghost Prince surprised.

"Hey! No injuring the patients!", growled Will annoyed.

"Where the Tartarus did those stupid Hephaestus-brats go?", muttered someone from outside.

The four Roman half-bloods entered the infirmary together, Jason's fingers linked with Reyna's, Frank's arm around Hazel's waist. The daughter of Pluto pushed past her friends to take a closer look at her brother, concerned golden eyes scanning him.

"How are you feeling, Nico? Why are you holding your face? Are you hurt?"

"He's hurt, because Percy slapped him", snickered Jake, walking up next to the son of Apollo.

Will looked a bit annoyed at Percy while leaning back against Jake's broad chest. The son of Hephaestus laid his arms around the shorter teen, resting his chin on the blonde's shoulder.

"Why are you all invading the infirmary?", grunted an annoyed female voice from behind Frank.

The Roman turned slowly around, looking sheepishly at his older, Greek half-sister.

"I just followed Hazel because she wanted to look if her brother and Percy are alright..."

"Yeah. And bird-boy and his chick decided to follow, too", snorted Clarisse and rolled her eyes.

"What did you do that for?", muttered Nico confused, ignoring all the others in the room.

"What did who do what for?", asked Chris confused, standing next to his girlfriend.

"Percy had slapped Nico in the face", explained Nyssa shortly.

"Oh, I would have like a dozen of ideas as to why", growled the daughter of Ares irritated.

"Me too", agreed Reyna darkly.

"Oh, I forgot to say; Leo's only a bit broody. All others are downright furious", chuckled Will.

"You knew the whole time! You knew me. You knew who I was and you didn't say a word", whispered Percy disappointed.

"You knew where Jason was the whole time", hissed the daughter of Bellona angered.

"You were probably the only one knowing what the fuck was going on!", growled Jason.

"Shut up", whispered Nico.

It truly was only slightly above a whisper, barely audible, but it silenced them all. Because the same moment the son of Hades talked, the room darkened just a bit and the shadows became only slightly longer. Not much, just enough to get noticed by the others.

"This is the infirmary. Annabeth and Piper still need time to rest. So get the Tartarus out of here."

"Right", snorted the son of Jupiter and crossed his arms in front of his chest. "Because we'll just leave and forget that you held the key for our every problem for months. You have been to camp before I got abducted by Juno. You knew about the Greeks and you knew about the Romans. It's time for some explaining, di Angelo."

"I don't have to explain myself to any of you", growled the son of Hades dangerously.

The shadows darkened only a shade and grew only an inch, but it was still enough to get the other demi-gods to finally move. Will was the last to get out of the cabin, closing the door behind him. The only ones left were Nico, the two unconscious girls and a very stubborn son of Poseidon.

"You don't really think I'll let you off the hook so easily", snorted Percy and rolled his eyes.

"No", murmured the half-Italian and shook his head. "Not you. Just them."

"Okay", nodded the Sea Prince slowly. "Then spill it. Why did you act like you didn't know me."

"Don't make it sound like it was easy for me", hissed Nico irritated. "Believe me, it was probably the hardest thing I ever had to do. You know how much I wanted to just... hug you?"

To just kiss you – was what he wanted to say. But that would have been a bit much for the moment.

"And why didn't you?", murmured Percy, wrapping his arms around his knees.

"Because I... I couldn't", sighed the son of Hades and leaned back. "I knew about the Romans, I have known for a while now. But I can't tell you why. Just... believe me that it was hard, okay? I truly didn't know you've been at Camp Jupiter when you disappeared. I went to search for you. And when I arrived back at Camp Half-Blood and saw Jason, I knew where you were. But you weren't there. So I kept coming back to Camp Jupiter to see if you'd turn up, but for months to go, you didn't. I couldn't tell the others, because they would have been way too worried and they would have asked questions. When you have finally been there... I was so glad to see you, but I knew you needed to regain your memories on your own."

"But were there... and you acted like you didn't know me", muttered the son of Poseidon sadly.

"I just said that it was hard for me, too!", groaned Nico and closed his eyes tightly.

"I know and I understand that... but it doesn't change that it hurt me."

The Sea Prince stood and left the cabin, too, leaving Nico seated on the bed alone, staring at the close door. Now that was just great. So not what he needed. Percy being upset with him. That always took way too long for them to get over it. Every time. He groaned unnerved.

"Maybe you should just stop screwing up with him?", whispered a soft voice.

"Yeah right. Because that's so easy, Annabeth", muttered the son of Hades annoyed.

"It could be", chuckled the blonde. "Six little words and everything would be alright again."

"Eh?", asked the Ghost Prince confused.

"I am sorry. I love you", intervened the native American girl next to Annabeth and yawned. "It's actually really simple. You should give it a try, death boy."

"Ah, you should listen to her. Daughter of the goddess of love and all that stuff", chuckled Annabeth and leaned her head against her girlfriend's shoulder.

"Just... shut up and suck faces or stuff", groaned Nico irritated and stood.

"Where are you going?", asked the daughter of Athena curiously.

"Following Percy, obviously."

"I wouldn't want to miss that", grinned Piper and stood, pulling the older girl with her.

The three got out of the infirmary and went up on deck, where a crowd had gathered around the steering wheel. Leo, trying to steer the big battle ship, with Jake and Nyssa next to him on either side, trying to help him. Reyna and Jason were standing at the rail with Frank and Hazel, Reyna screaming something at her sister, who was in the air on Reyna's pegasus Scipio with Kinzie clinging to her back. Next to Scipio was Blackjack, whining desperately, with Thalia and Phoebe on his back. The tropes of the Amazons and the Hunters were right behind their leaders, trying to help. Tyson was holding Mrs. O'Leary back, the dog barking angrily at the sky, Ella flying around the two of them. There was Clarisse coming up next to her Roman half-brother, shouting at her boyfriend and the Stolls. Octavian was cackling like this was the most joyful day of his life, which in itself was enough to make Nico nervous. Will was running around deck, trying to fix others with the help of his siblings Austin and Kayla. There were Malcolm, Grover and Rachel, trying to get Piper's siblings and the Gardner sisters down to safety, Drew screaming on the top of her lungs, Mitchel and Lacy looking frank and fearful, Katie's hand linked with her boyfriend's, Malcolm throwing a meaningful look at his half-sister. Miranda turned around, staring at Lou, who hastily ran up to her girlfriend and the others, murmuring soft words, probably trying to put a spell on the storm.

"What's going on here?", asked Piper as her siblings ran up to them.

"Just look into the sky!", grunted Grover and pointed up, somewhere between the pegasi.

The three concentrated hard, trying to figure out what there was between Scipio and Blackjack. A cloud. A dark, stormy cloud, swirling around, making strange forms.

"What in the world is this...?", muttered the daughter of Aphrodite concerned.

"I have no idea! Come on, let's check it out!", urged Annabeth, leading the two closer.

As Piper, Annabeth and Nico came up next to the Romans and Clarisse, they finally clearly saw what it was. It wasn't just a storm, it had a face, the face of a woman.

"Is that... But Gaia is the deity of the earth I thought...", whispered Piper confused.

"That's not Gaia", answered Jason. "We don't know what it is, but it got Percy."

"What?", growled Nico wide-eyed, staring at the cloud-woman.

It was true. The woman-shaped cloud was holding someone in his hand, someone who was way too important to the son of Hades to let her get away with it. He flexed his hands, trying to hold back, all he wanted to do was jump up there and get his Sea Prince, but he couldn't.

"Grace, move your sorry ass up there and get him down!", demanded the Ghost Prince angered.

"What am I supposed to do, di Angelo?", hissed the blonde back. "I can't get close."

"That is right, little ones", whispered the wind into their ears, the voice seemed to come from everywhere. "You won't get close to me. And you'd better not try. Because you wouldn't stand a chance against me. I am a force too great for you."

"Who are you?", screamed Thalia at her, trying to fly closer with Blackjack.

"I am Chaos, the oldest and most powerful deity in existence."

"Great, because we're not having a hard enough time fighting Gaia", groaned Frank annoyed.

"I am not here to fight you", called the wind to them.

"Then return Percy!", demanded Nico outrageous.

There was laughter ringing in the wind, laughter so light and amused but still a bit psychopathic that it shook the teenagers. Something was off. What did Chaos want from them? And why did she take Percy? Nico's yaw tightened. No one was allowed to take his Sea Prince away from him, he still had Hera's ass to kick for the last months without Percy.

"Don't be so angry with me, heir of Hades", whistled the wind. "I do not plan on hurting him. There's something I have to show him, a lesson he has to learn."

"Why? Why him? Where do you want to take him?", screamed Nico.

"On contrary to your beliefs, not every deity older than the gods is evil", there was a certain smile evident in the voice. "For you to win against Gaia and what is about to come, you need to learn a lesson about yourselves. And I will teach you this lesson."

Chaos opened her mouth, though it was so much more like a tornado behind those cloudy lips. And then she tossed Percy inside. Wide, fearful sea-green eyes stared at the Argo II.

"Nico!", was the faintest thing they could hear from him, before he disappeared inside the storm.

"No!", screamed the son of Hades, his knuckles turning white as he gripped the rail hard, ready to jump over it to get to the boy he loved.

"Don't be ridiculous, Nico", whispered his sister, her hand on his wrist. "What do you plan on doing? Jumping after him into certain death?"

"You don't understand, Hazel!", growled the Ghost Prince.

"I understand perfectly. I've understood it the moment I introduced you two", smiled the girl softly. "You love him. I'm not stupid, Nico. I know you love him."

Gritting his teeth, he averted his eyes. "I can't just stand here and do nothing."

"That's the reason we are going to follow him, dumbass!", interrupted Leo as loud as possible. "And now get to work, everyone! We need to fasten the sails and everything loose and then I want everyone to get below deck!"

"What are doing, Valdez?", asked the son of Hades surprised.

"I'm gonna bring us through that storm. I didn't built that ship to fetch Percy Jackson so some other crazy woman can take him away again", grinned the Latino.

"Everybody!", called Jason. "Do as he says! We're gonna get Percy Jackson back!"

Cheers could be heard all over deck and the half-bloods started moving, both Hunters and Amazons landing on board again to help. Soon everything was ready and the teenagers got below deck.

"You too", ordered Leo, trying to concentrate on navigating through the storm.

"You're gonna need help, Valdez", smirked Nico and got next to the son of Hephaestus.

"He's right with that one, Leo", smiled Piper, gripping the wheel on Leo's other side.

"I'll try influencing the storm to our advantage, but I doubt it'll work out considering that that's the doing of a higher deity", sighed Jason, his face contracted in pure concentration.

"We need to get through this storm fast, but you need to slow down for that. The force we're facing is too strong, we'll crash if we go full force into it", commented Annabeth with scrunched eyebrows.

Together they worked their way into the gaping mouth of their newest enemy, sailing through the wildness of the storm. Once they got out again, everything was dark for a split second before it turned into normalcy again. A normal sky, stormy but with regular storm-clouds. Though as soon as they were settled at least a bit, something came crashing down on deck. Since the shaking of the ship finally stopped, the other half-bloods got out again to take a look at where they were.

The something that had come crashing down on them moved and groaned.

"What a shitty landing, Blackjack", groaned the boy.

He wore faded, black jeans, a skin-tight sleeveless shirt and a leather jacket tied around his waist. Black hair was styled into every direction.

"Who... Who are you...?", whispered Nico dumbfounded.

The boy turned to them and snorted, sea-green eyes glinting with mischief. He spread his arms out and walked some steps closer to them, a wicked grin on his black-painted lips.

"Who do I look like? I'm Percy fucking Jackson, second in command of our high Lord Kronos", chuckled the teen, putting his hand into his pocket, pulling Riptide out. "What I would want to know though is: Who are you? Because I'm pretty sure I've already killed most of you."
