DISCLAIMER: All rights belong to Rick Riordan, as well as the characters (except for a few characters that I might create myself).
This is just a fanfiction. If you haven´t at least read Percy Jackson and the Olympians and Heroes of Olympus, you probably won´t understand half of the story.
The story will be written focusing on different characters every so often (Heroes of Olympus style).
English is not my native language and I would like if you pointed out any mistakes in the reviews.

This is my second story. I'm still publishing the other. Not to worry, though, as I will continue to update both of them.

I appreciate any reviews and ideas.

Now, on with the story.

Chapter Four – Percy's Birth and Powers

CHAOS

The creator of the Universe looked at her true son. She lost a big part of his life because of the dammed war. Now, she came to claim him and unlock his true power. She looked into his eyes and saw doubt and… anger?
Such thing pained her. She shrank to human size and approached a quiet Percy.

-I know you must be angry at me for keeping this from you… But will you give me a chance to explain? – when she finished talking, she had tears coming down her face.
To her surprise, Percy hugged her.
-I could never be mad at my mother. But I do want an explanation.

To Chaos, this was the happiest moment of her immortal life, right up there with Percy's birth. She sat with him and Annabeth by the hearth. Order joined them. Everyone was listening carefully.

-I guess I should start at the beginning.
I've had many children: Gaea, Uranus, Nyx, Erebus, Aether, Tartarus… But I created them all using my power. They weren't my flesh and blood.
Like all women, I strived to be a mother, to give birth. So, after a long talk with my brother, we decided on artificial insemination. Nineteen years ago, he started to look for the perfect… donor, at the lack of better words. And he found it here, on Earth.

It was Order's turn to explain.
-He was a legacy of Poseidon. He had all the characteristics my sister was looking for: loyal, concerned with others, strong, a good leader… He was a firefighter, actually. A captain, no less. He was more than happy to help. As a reward, I shielded his scent and his descendants', other than you, of course, from monsters forever.
-Is he still alive? – asked Percy.
-Unfortunately, no. He died saving a little girl from a fire in a house.

Chaos continued the story:
-Afterwards, Order came back to me. Nine months later, you came along. It was the happiest day of my life. The pain was horrible. – some goddesses smiled sympathetically at this statement – But as soon as I heard you cry, it was all worth it.
Chaos's eyes became sad and her expression dark. She continued:
-But it was also the saddest day of my existence for it was the day I had to leave you.

-Why did you do it? – asked Percy
Tears were pouring non-stop from the eyes of the Creator.
-Because, my dear son, we were at war, at the time. After you were born, I was weak. I couldn't let the enemy know of your existence and I wasn't strong enough to protect you. So, I took the toughest decision of my immortal life: I sent you to Earth.

Almost every goddess in the room had tears in their eyes, as well as some gods such as Apollo and Hermes and even Poseidon. Percy was now hugging his mother and crying as well. Annabeth was fighting back the tears, but failing miserably.

Order was the one who continued:
-After taking Chaos to a safe haven for a while to recover, I brought you to Earth. But even before that, right after you were born, I too was very happy. You were such a small, frail, little thing. And, with my sister's consent, I adopted you as my own son. Leaving you was the hardest thing I've ever done. I searched for a couple who would take care of you. Surprisingly, I found it rather quickly and in the most unsuspecting of places: Poseidon and Sally Jackson. I found that rather ironic, giving who your father was. Chaos came up with a plan. They had been trying to have kids for a while, unsuccessfully. So, we tempered with both their memories, making them think you were their own.

Chaos lifted her head, facing Percy with her teary eyes.
-After that, you know the story better than we do. And that's how it all happened, and why you are what you are. Please, Percy, understand that I would never have given up on you if there was another way. But it was the safest option. Do you forgive me?
Percy hugged her tightly.
-Of course I do! It must have been hard for you. I had a mother and a father, but you were deprived of your only son. How could I not forgive you?

They just stood there for a while, hugging each other. Hera whipped a tear from her eye. Every other goddess had a silver trail of tears running down their cheeks. Apollo whispered to Hermes:
-That's got to be the saddest story I've ever heard!
-True that, bro.

After a while, they let go. Annabeth raised a hand.
-Lady Chaos, do you mind if I ask a question?
She smiled at her.
-Of course you can, Annabeth. After all, you are almost family. – both she and Percy blushed heavily – What, you didn't think I would be watching you, Percy? Well, you're wrong, and let me say this, I couldn't be prouder!
Percy smiled and gave his mom a smaller hug.

Annabeth continued her question:
-What about his powers?
Chaos was quiet for a while, wondering if she should respond. Then she answered:
-As my son, Percy can control every element in creation, talk to animals and instantly know what plants are good to eat or heal, as well as which ones are poisonous, amongst other things.
Order joined in:
-And, as my adoptive son, Percy can control matter and pretty much every type of energy you can think of. Matter manipulation will allow for him to turn invisible, for example, amongst other useful powers.
-But why can he only use water powers, then? – asked a curious Athena. Like mother, like daughter.

It was Order who, once again, answered the question:
-That's my doing. You see, Percy was so powerful I had to place a seal on his powers, with my sister's help, so he wouldn't accidently kill someone just because he was hungry or throwing a temper tantrum or something like that. Because he would be living as a son of Poseidon, we only made his water related powers available for him. The seal was meant to hold for twenty years. But you exerted yourself so many times fighting for your friends that the seal started to crack. That's why you have been having splitting headaches, Percy.

Chaos stepped in:
-Fortunately, the war is over and we were able to come to Earth and claim you; if not, your powers would awaken shortly and you would probably decimate everything around you in a mile radius. With us here, the power can be contained. My son, are you ready to get all your powers?
Percy nodded.
-I am. – he said.

Smiling, Order touched Percy's forehead with two fingers; then, Chaos gave him a motherly kiss in that same spot. The wave of power that followed cracked some of the marble columns. Before their very eyes, Percy changed: he became a tad bit taller and his muscles more defined; his black hair now had some white highlights, which made it look even better. But his eyes… When Percy opened them, they were just like Chaos's.

-Oh wow… - said a blushed Aphrodite.
-What? – asked Percy, oblivious as usual.
Aphrodite just mad a full body mirror appear. Percy looked at himself and blushed.
-Oh… - he said.
Then, he saw his eyes and gasped.
-How do I hide these? – he asked.
Chaos was about to answer but Annabeth interrupted her:
-Don't. They are beautiful.

Percy smiled at her and gave her a small kiss in the lips.
-Well, looks like you need some space. – said Zeus – We will leave you. You must have a lot to discuss.

Having said that, every Olympian flashed out, leaving only Percy, Annabeth, Chaos, Order and Poseidon.
