(A/N: Ok, before you start to read this fan fiction, I will give you some tips. I know that there are like so many different fandoms in this fanfic but please don't be put off. For the most part, they are just one-shot encounters and you probably won't see the fandom again in the story. If you come across a fandom you don't know, you can easily work it out, the characters are easy to understand and you can probably understand the storyline without 100% understanding the characters. If it is something big that you don't understand, then it will probably be explained later on, if not, feel free to PM me. As I go along with the story, I will make a list of all the characters on my profile so you can identify any that you don't know. The only fandom you can't work around, is the Percy Jackson fandom. You are gonna be pretty lost in the story if you don't at least kind of understand the PJO or HoO fandoms. Sorry. Explanations over, please enjoy the story.)

Prologue:

Percy Jackson stood stiffly next to the outcast son of Jupiter. His eyes wondered yet again over the place he used to call home.

"Percy?"

He smiled as he saw a figure clambering up Half-Blood Hill. Nico came to stand next to him. Nico Di Angelo, the only one who had not yet abandoned him after the war.

Once the battle against Gaia had finally ceased, Annabeth confessed to him that it was too painful to stay with him. Every time she saw him, the memory of Tartarus 'haunted' her. Percy didn't blame her for this though, nor did he feel any disgust towards her when she came out as lesbian and got with Piper. It was the fact that she had started to deliberately avoid him, ignore him even since Adam Colton got to camp.

Adam Colton was an unclaimed demigod, arrived about three weeks after the war ended. Percy wasn't throwing about any wild accusations, but as soon as he got to camp, one by one all of Percy's friends seemed to desert him or find a reason why they disliked him.

Clarisse and the Ares cabin had a newfound hatred for him, because he humiliated them in the training room, with his wrestling and sparring skills greatly improved after the war. He felt hurt by this because he had grown quite close with Clarisse over the second war final stand.

Travis, Conner and basically the entirety Hermes cabin had started to shun him and mock him for trying to prevent their pranks on unsuspecting cabins.

And those 'unsuspecting cabins' where indignant of Percy's help, feeling that he was treating them like weaklings. Gradually they began to shirk away from him as well.

Leo was never that fond of Percy since they had met. At that point, Leo had heard so much about Percy, he was practically worshiping the ground he walked on, and Percy, who wasn't keen on fame and stuff, sort of rejected him. Leo had never really forgotten it and seemed start to remember it quite strongly since the war.

Thalia hardly ever saw Percy, what with her being the Lieutenant of the Hunt. She was so busy that Percy hadn't actually seen her since two weeks after the war.

With Annabeth and Piper avoiding him so much, he really needed Grover to lean on, but he wasn't there either.

It wasn't that Grover disliked him; it's just that he was so wrapped up in his Lord of the Wild stuff that he failed to notice Percy's mental state deteriorating as he became more and more isolated.

Nico was there when he could be, but he too was being drawn away from Percy in the form of working in the Underworld for his dad.

Poseidon had claimed Adam as his honorary son, which Percy didn't object to as he had done some pretty cool shit on the quests that he'd been on. Adam was reasonably nice to Percy most of the time, it's just everything he did seemed unnatural, fake. With Adam to fuss over Poseidon didn't contact or talk to Percy as much. In fact neither did any of the other Gods.

Percy was slowly but surely being pushed into the background.

The final blow was when his parents died. He was distraught; the police reported that there was a nearby explosion from a gas pipe, which caused a fire that killed both Paul and Sally. But Percy knew that in his world, suspicious things like this weren't coincidences. Either a rogue monster killed them, or someone or something had been sent to kill them.

When he found out, there was no one there for Percy to lean on.

Annabeth should have helped him…but she didn't. Grover should have realised… but he didn't. Thalia should have been there…but she wasn't. Poseidon should have noticed…but he didn't. Someone should have helped him…but no one did.

When Nico returned from the underworld five weeks after the war, he found Percy locked in the Poseidon cabin, half starved and in a severe state of depression. He tried to get people's attention, but they brushed him off. He did what he could for Percy but he couldn't do much by himself.

He contacted Jason to try and get help from the Camp Jupiter, but instead found out Jason had been outcasted. Reyna had turned bitter on him for the relationship rejection he gave her, and when Octavian succeeded in charging him for breaking the ancient laws by travelling to Rome, she did nothing to stop it.

He, like Percy, had lost his girlfriend after the war, and felt almost as broken as Percy. A similar thing was happening to Jason, people had started to ignore him or find reasons to dislike him.

Percy and Nico had decided to leave and join Jason.

The night after they had agreed to this, they had a dream with a mysterious deity:

FLASHBACK –

Nico opened his eyes, he was definitely still asleep - his body was sluggish and unresponsive.

He looked slowly around; he was sitting on a chair, still in his pyjamas. There was a bright spotlight shining directly down on him. It was making him feel uncomfortable and he could not see anything in the shadows around him.

Suddenly another spotlight lit up next to him. It was Percy, who clearly looked a little startled from waking up in a dream on an uncomfortable wooden chair under a harsh white light.

Before Nico could call out to him, another spotlight lit up, on his other side. This time it was Jason who looked even more uncomfortable, as it became apparent that he only slept in his boxers.

"Perseus Jackson."

"Niccólo Di Angelo."

" Jason Grace"

A deep shadowy voice rumbled. The sound seemed to surround them, not coming from any point in the room in particular. It sort of felt like they were on trial for something as the insensitive lighting glared down at them.

Each of them felt uncomfortable hearing their full names.

The enigmatic voice continued, " You each have served your life well…"

They all winced as they heard 'have', did that mean that this powerful sounding deity that was controlling their dream would end them? Nico started to panic.

"I can see you are beginning to fade amongst your current companions. Whilst I cannot stop this, I can offer you a new life."

Jason frowned. Percy blinked. Nico froze.

" What?"

The words slipped out Percy's mouth before he could stop them.

"Sorry! Uh…sir? I mean um, I would be flattered but why? And who are you? Uh…sir?"

The voice chuckled, lights flared up around the room - no hall they were sitting in. A large and impressive being sat on a black throne in front of them. There were pinpricks of light on the throne as if it was made up of the galaxies. Nico could not see much of the figure as it was mainly in a shadow, but he could feel the power that radiated off him…it? The raw power felt like this being could destroy each of the Olympians and barely lift a finger.

Percy gulped.

"I'm afraid I cannot reveal who I am until you accept. But in answer to your first question: I can tell you are very talented young people, whose lives are rapidly approaching their end – far too quickly for my liking. I offer a new life to people who I feel deserve it. No, you do not get reborn, you keep your memories, but you gain a new identity and never have to reveal your old one"

Jason cautiously ventured a question "And what would we do in…our new life?"

"You would train, mentally and physically. Gain powers, learn how to wield and manipulate things. Meet and befriend people like you, who have lost hope in their original lives. Get new names. Become protectors in a sense. Immortal protectors that do not live on earth."

Nico's face scrunched in confusion. "Sorry sir, I do not understand. We would not live on earth? We would be immortal? We would leave our old lives behind and start afresh with people we've never met before?"

The being smiled. " Yes, to all. Should you accept this, go to the top of Half-Blood Hill tomorrow at 10pm. Jason, if you agree you shall be teleported there by me and we shall continue from there."

Each of the boys saw darkness fill their eyes and gradually each awoke, filled with questions.

FLASHBACK END –

Of course the boys had agreed to it, they had decided on leaving their old lives anyway, why not take up this mysterious and generous offer?

So, back to the present where the three stood, taking what was probably their last ever look at the Greek Camp.

A black portal shimmered into existence in front of them. Out stepped a scaled down figure that they had each seen in their dream. He wore a galaxy-covered cloak that seemed to melt out of the portal.

"Good decision boys" boomed the man.

Each of them felt a tickling sensation as they were pulled through the portal and once again found themselves in the massive hall in front of the throne, this time standing.

The man smiled down at them in a fatherly way.

"Welcome to the Void. I am Chaos and you are about to join the Legion of Chaos"
