In the end Chiron explained everything to "me", while I sat outside the Big House looking at the stars. I missed everyone back in 2009 so much, it was so unfair. I would not get back for years, while to my friends only seconds had passed. And now Kronos was going to battle here! I sighed, it was going to be so impossible to do this.

I looked up at the stars and started to cry.

"You alright, Percy?" a voice shouted.

I shook my head and looked behind me.

There, stood Thalia. "I just want to go home!"

Thalia ran up to me a shrugged. "You'll be home in a few years, and anyway. Camp is your home. I'm sorry,"

"I might never go home. After all, we have to fight Kronos- we might lose."

"We won't lose Percy because... I've had an idea. We need to go to Olympus. This idea though, it's gonna hurt you. A lot. But we will win."

"What is it Thalia?"

" I can't tell you Percy. You wouldn't let me..."

With that she hit me over the head! I did not believe that Thalia would ever do that, but it seemed like she had been changed. Perhaps me being in the past damaged a lot of people...

I groggily sat up as soon as I woke up, and found myself in the Big House. Thalia was sitting in front of me, talking to a hooden figure. The man dissapeared in an instant, and Thalia turned to me.

"Sorry about that..." she said casually, as if she really wasn't sorry at all.
"Who was that?" I asked.

"Lord Hades. If we travel to the River Styx, and bathe in the waters, then we will become invunerable"

"Hades was here? Invunerable?"

"Like Achilles, hard to kill." She ignored my first question.

"It's dangerous though," I said, hesitant.

I sat up slowly,rembering the entrance to the labyrinth - and knowing that that would be the easiest way to get there- I led Thalia there and we set off across the labrynth.

"Thalia, there's something I should ask you. Do you want to be the child in the prophecy?"

"No. Why? We can't change it."

"But we can. You could join the Hunt and I could go to the Lotus Casino - where you seem to never age."

"Yeah but would you really do that? Leave the fate of the world to chance. Not fight, not try to save everyone."

"Well why not. Why can't we just let everyone save themselves?" I asked her, frustrated.

"Because. We're half bloods, it's what we have to do."

" Well I'm sick of fighting. You know what, I'm leaving. Everyone can do this themselves." I ran back the way we had came through the labrynth. Surprisingly I made it back to camp quite quickly and didn't get that lost.

Stabbing at a dummy in the sword fighting arena I saw Luke walk up behind me. He started to stab at the dummy next to me. Tensly I tried to ignore him, he wasn't a traitor yet.

Suddenly, and strangely, Lord Hermes arrived. Angrily I walked up to him. "Why couldn't you stop your traitor son? You know what he's going to do - so why don't you stop him. He's going to become Kronos and he's going to kill us all!"

Lord Hermes didn't attack me like you would expect. "Insolent child, how do you know that?"

"Because it's true. Because I saw it happen. Because I'm from the future. And can't you see in his face what's happening?"

Hermes looked at me sadly. "Oh, Perceus Jackson, I know his story, I know the end and I can't interfere." Then he looked me straight in the eyes.

"And I know what's going to happen to you child ." His eyes shone black, and he glared at me. I gulped - wondering what exactly he knew...

"Please Lord Hermes, can't you do something to stop him?" I whispered.

He shook his head and disapeared in golden smoke. Luke hadn't even glanced at his father though - as if he hadn't even seen him.

I couldn't help but remember his words - And I know what's going to happen to you. He knew how it was all going to play out, but he wouldn't do a thing. Us halfbloods were alone. And there was nothing we could do to save ourselves. We could fight. But we would probably lose. Or it could end right now. There would be no final battle, no heroic last stand.

I stepped in front of Luke. "Don't. Just don't. Don't betray us. Don't betray Thalia! Don't betray Annabeth. Don't betray us all!" I screamed.

"What do you mean?" His confused grimace, made my blood boil even more.

"Kronos,"

Thunder crashed overhead but I just ignored it.

"Betray us and it's over."

"What do you mean?"

"I mean, that Thalia will join the Hunt and that I know what we will all have to do. Luke, I know what will happen to you if you do."

"You're not a god Percy, you don't know the future."

"I know I'm not, but I know you're fate. If you don't believe me, ask your father. Ask Lord Hermes."

With that,I walked away into the night.

2 MONTHS LATER

Camp Half Blood was under seige. Me and Thalia were sitting by the borders staring at the entourage of monsters outside. If we passed the borders we would be slaughtered instantly.

I looked over at my friend and sighed. "You know this is my fault don't you, Thalia?"

"How could all this be your fault Percy? It's Luke's fault."
She deserved the utter truth. "I shouldn't be here, this is really... it's just wrong. You should be... in the Hunt."
"Percy, I would never join the Hunt"
"Not now you wouldn't. But in the future you would"
"You always say that. You say that you're Percy Jackson- that new kid - from the future. But that is impossible. There is no such thing as time travel," Thalia said firmly.

Sighing, she glared at me. "What's your real name?"
"Percy Jackson,"
"So, what, you have the same name?"
"No! Forget it..."
"We'll continue this 'discussion later'" Thalia said, before singing my eyebrows with her powers.
Bitterly, I though to myself - if there even is a later.

The fights continued, bloodshed, seemingly eternal.

And I stood by the sidelines, frozen. I was about to fight Kronos.

My friends were falling, and I still had to fight.
Seeing Kronos, now in the form of Luke, just like I had predicted, Thalia and I lunged. Something filled my mind - just a sentence. "It is your duty"A reminder that I had to fight Kronos. Otherwise Camp, and the Western World, would fall.
I stabbed Kronos, and he fell backwards a step. My heart thudding with adrenaline, I continued.
As we fought on, the other fights stopped. Thalia was getting tired now and I knew that we had to end the fight soon, or there would be no chance of victory. Suddenly, I fell to the ground, and saw Kronos standing above me. He had knocked me to the ground with a kick - a cheating move. Groaning, I stood back up to see that he was holding his scythe threateningly...
