Chapter one:

Present time at Camp Half-Blood

Chiron POV

As I looked out upon camp from the porch of the big house, I started to think about what was happening in our world. Kronos, my father, was rising. The campers were starting to train a lot harder. War, or as they called it the second Titan War, was upon us. I thought of Nick, the hero of the prophecy since Thalia, daughter of Zeus, joined the hunt; he was a disappointment. When Poseidon claimed him I started hoping that we still had a chance, I thought he would be like Percy, caring, loving, loyal, selfless, never accepted a complement, always turned to others. I was wrong; Nick was arrogant and boastful.

My mind drifted to Nico Di Angelo, I knew he was a son of Hades. I knew he was one of the greatest heroes that disappeared 150 years ago. He ran away last winter when he learned that his sister died. He was unfortunately a couple months younger than Nick so he couldn't be the hero of the Prophecy.

I saw in the arena that Clarisse, Daughter of Ares, was going to start a fight with Nick. He wasn't very liked, so I didn't know how he was going to lead the demigods into battle if they didn't listen. When I got to the arena, I noticed that the fight was Clarisse, Katie, daughter of Demeter, Grover, the Stolls, sons of Hermes, and Malcom, Son of Athena, against Nick, Annabeth and his goons. I galloped into he arena and yelled:

"Stop! It's the fourth time I've had to stop a fight in between your two groups. We are in the middle of a war!"

"My cabin and I will not go to war with this Son of a Gorgon leading us" replied Clarisse. It surprised me that a child of the war god didn't want to fight; she continued her speech. "He thinks that he's the best because he is the hero of the Prophecy."

"Well he is the best."

I turned around to see who had spoken. To my disappointment it was Annabeth; she had always been like a daughter to me. As a little girl she had been nice, caring and helpful, but ever since Nick showed up she stated to change. Now she was a camp bully, always let the others do the hard work.

"He thinks that he's the greatest hero of all time," said Malcom, "Everybody knows that Hercules was the greatest hero of all time."

I decided to stop the fight then and went back to the big house and got into my wheelchair form. This greatest hero of all time talk got me thinking of the real greatest hero of all time, Perseus Orion Jackson, Son of Poseidon.

I decided to I-M Poseidon. I still thought about Percy, since he disappeared 150 years ago, Poseidon has banned all talk about him and his team. Percy Jackson, Son of Poseidon, Nico Di Angelo, Son of Hades, Bianca Di Angelo, Daughter of Hades, Grover Underwood, Satyr, Lucy Morrow, Daughter of Zeus, and Samantha Jade, Daughter of Athena.

The screen of mist and Poseidon appeared. He was in a room with drawings of one of his sons on a quest. I recognized the drawings too well, they were Percy's quests and I had the same ones. I looked at Poseidon and saw him weeping, that's when I remembered that today was the day, 2nd of June, that Grover entered camp bloodied and half dying saying that the rest of the team was gone. Today was the day of Percy's disappearance.

"Lord Poseidon," I called out hesitantly, not sure if I should bother him. He turned around his eyes were bloodshot.

"Ah Chiron, it's been 150 years, Nico and Bianca came back, Lucy came back, but my son is nowhere to be found." He said sadly. I was shocked; I hadn't known that Lucy had come back. That's when it hit me.

"Thalia," I whispered. Then I remembered why I called. "Lord Poseidon, Your son Nick has been causing problems lately. He's arrogant and calls himself the greatest hero of all time."

"Really? Well I guess I'm not surprised. I wish he were more like Percy,"

Poseidon had a far away look as he said that.

"Lord, I think it is time." I declared, "Time they know the story."

Poseidon looked at me then at the drawings and said, "I think you're wright, I'll contact Athena, Hestia and Artemis. You know that they would want to be there. I'll see you at the camp fire."

He swiped his had threw the mist and I turned towards the wall where the pictures of all my favorite students are. I took down some of the pictures to uncover a safe. I opened the safe and took the same drawings Poseidon was looking at out of the safe. I decided to look at them to decide what I wanted to say. I turned towards the door and saw that it was night time. I headed down to the camp fire to begin the story.
