The room immediately turned into chaos. The younger students started panicking for their lives, while the older students tried to calm them down.

After a few minutes, Dumbledore shouted, "Silence!"

The everybody froze in their tracks.

He continued, "Teachers, take the students to the common rooms. Fifth, Sixth, Seventh and Eight years, remain here."

The teachers scrambled to take the students away.

Once all the younger kids were gone, I took the podium and said, "Go get your armor and weapons. Meet Thalia and Reyna here in 20 minutes."

As I stepped down from the podium, Thalia looked at me with worry, "What are you gonna do?"

"I going to force the army to take the land route. It'll give us an extra hour or so. Artemis, go to Olympus and get all the immortals you can. We'll need all the help we can get."

Artemis nodded before flashing away.

For my 17th birthday, my Dad gave me a new bead for my necklace. Whenever I pull if off, my clothes turn into my own set of armor.

The armor was black with navy blue pads. On the chest plate, was a raised gold trident, and the sleeves were also black with navy blue pads. My gloves were black with a sea green palm. My fingers were exposed so I could easily grip Riptide. I also had a navy blue hood that covered my face, so all you could see was the lower part of my face, and my sea green eyes glowing under the hood.

My dad also had Hephaestus enchant it so it would be as light as my training outfit, my camp shirt and shorts.

I pulled the bead off and vapor traveled to the docks.

From what I could see, there were at least twenty ships carrying monsters and Death Eaters.

I summoned some lightning and created a mini hurricane. As the waves began to rise, the smaller ships were forced to turn back.

Even though the hurricane was slowing down the larger ships, they were still moving toward the castle.

I used my powers over air and water to create some waterspouts.

Many of the ships started to turn back, in fear of being destroyed by the waterspouts.

Once they were out of view, I went back into the castle.

Many of the older students were surrounding the castle, activating some of the castle's defenses. 

I pulled off my hood and made my way into the Great Hall.

Dumbledore was talking with some of the teachers, along with Thalia and Reyna, when he noticed that I had arrived. "Mr. Jackson, what do you plan to do next?"

On a table was a map of Hogwarts and the surrounding grounds. It showed where everyone was at the current moment, and where they were headed.

I pointed at Hagrid's cabin, "I forced the army to come in through the Forbidden Forest, so we should set up here. While the first line is being set up, I'll go and ask for help from the centaurs in the forest."

Professor McGonagall asked, "Why would the centaurs help us?"

I smirked, "Because Kronos hates centaurs."

I let my answer hang in the air for a few seconds before continuing. "As we speak, Artemis is assembling as many immortals as she can. But we can't wait for them."

Everyone nodded before dispersing to their assignments.

I pulled my hood back on as it was now pouring outside, and went to Hagrid's cabin.

When I got there, the wizards had just started to set up. Harry, Neville, and Ron were setting up access points to the cabin's roof. That way, the archers can get into the cabin for cover.

Inside the cabin was a makeshift infirmary. Here, we would treat minor injuries, while major injuries would be taken care of in the castle's infirmary.

Apollo told me that because wizards were either blessed by the gods or are legacies, they can have no more than a shot of nectar. So we have three whole barrels of nectar. But they would only be used if wizard magic won't work.

Draco was helping to add cannons to the field. That way we can have heavy artillery backing us up, and to shoot at monsters that were farther away.

Ginny and Luna were helping with building large bins to hold the celestial bronze cannonballs.

Hermione was adding protection spells to the cannons, so they can't be destroyed or taken over by the army.

I made my way into the forest, and after a few minutes of walking, I came across a colony of centaurs.

Some of them pulled out there bows and pointed them at me.

I put my hands up in surrender and said, "I need your help. My name is Percy Jackson."

Some of them looked at me with curiosity, while others pulled back their arrows, preparing to fire.

One of them stepped forward and said, "Some of us don't believe you. We have heard of the Savior of Olympus. Pull off your hood, and reveal if you truly are him."

I nodded before pulling my hood off.

Some of them gasped while they lowered their bows.

The centaur bowed, "My name is Firenze. It is a pleasure to meet the legendary Son of Poseidon."

"I'm sorry to disturb you at this time, but Kronos has returned. And he is using Voldemort as his host. As we speak, his forces are marching through the forest."

Firenze's eyes widened.

I continued, "We need your help."

Another centaur asked, "Why should we help the wizards?"

"Kronos is not a big fan centaurs. His forces will kill you just because you are centaurs."

The centaurs huddled together, deciding on what to do. Hopefully, they'll agree. Their help could be a big boost to us.

After a few minutes, they split and Firenze said, "We will help you."

I smiled, "Then please follow me."

They all nodded, and followed me out of the forest.

By the time we returned, all the defenses were set up. Thalia, Reyna, and Sevvy were inspecting everything, leaving nothing untouched.

Hermione was the first to notice us. She announced, "They're back!"

Everyone looked up from their positions and looked at the centaurs with worry.

Firenze assured, "We are not here to hurt you. We have come to aid you in your battle against the Lord of Time."

Some of wizards still remained skeptical.

I spoke up, "I swear on the River Styx that the centaurs are here to aid us."

You could hear the thunder in the background, indicating that the oath had been made.

I guess the wizards took that as an answer, because they didn't indicate otherwise.

I told the centaurs to send their healers into the cabin, while their archers went to their positions.

As inspections were finishing up, an owl dropped a letter at my feet.

I opened the letter, and it said:

Percy,

Kronos' forces are about to exit the forest,

               Dumbledore

I dropped the letter and yelled for everyone to get into position.

I shouted, "Draco, Harry!  Join me at the front of the defenses."

As the army poured into view, everyone was in position. Harry, and Draco pulled out their swords, preparing for battle.

I uncapped Riptide, pulled up my hood, and yelled, "CHARGE!!!"

I ran to the nearest monster, a dracaena. I stabbed it in the gut, turning it into gold dust.

Next was Death Eater. He pointed his wand at me, and shot a spell.

I ducked out of the way, the spell missing me by a foot. I slammed the hilt of Riptide into his head, knocking him out cold.

After I killed a few more monsters, I heard a shriek.

"Perseus Jackson!"

I turned to the direction the shriek came from, putting me face to face with Kelli.

I sighed, "Didn't I just kill you like two months ago?"

Her face turned red with anger. She said, "I guess I'm that important to Kronos."

Using my blessing from Hermes, I stabbed her in the chest before she could even blink.

I slashed through some more monsters before I saw Harry in the mud, with a Gorgon about to kill him. More specifically, Stheno.

I threw a fireball at her head, putting her off-balance.

Harry quickly shot a spell at her, causing her to fall over.

I knelt down next to her and stabbed my sword into her body. As her body turned into golden dust, two vials of blood were left behind.

For the first time, Harry looked at me without hatred in his eyes. He offered his hand, to pull me up, and said, "You saved my life. So I guess your not as bad as I thought. Sorry about being a dick."

I grabbed his hand and nodded.

I picked up the vial on the right and showed it to Harry. I said, "This vial right here will heal any injury. I'm gonna go drop this off in the cabin. You and Draco are in charge. If you see Kronos, immediately fall back into the castle."

He nodded as I stepped on the vial with the deadly blood.

I vapor traveled into the cabin, startling some of the centaurs.

I handed the lead centaur the vial and explained to him what it did. I then told him to use it for an emergency, as there was only one dose.

Before I was about to leave, an owl dropped another letter for me.

It read:

Percy,

The monsters are crossing the Great Lake again. It looks like Kronos is with them,

          Dumbledore

I dropped the letter and vapor traveled back into the forest.

I saw Harry and Ron killing a few monsters, while Hermione was shooting some spells at a Death Eater, watching Harry and Ron's back.

I sped over to the Death Eater that Hermione was firing spells at. I slammed my hilt into his head, knocking him out.

Harry and Ron turned to us and I said, a little out of breath from the vapor traveling, "Monsters are crossing the Great Lake. Kronos is with them. We need to stop them."

The Golden Trio nodded before running out of the battle.

"Perssssseussssss Jacksssssson, you will die!"

I turned to see Stheno's sister, Euryale, licking her lips, "You will be very tasssssty."

She lunged at me, trying to slash me in the face with her claws.

I blocked the strike with Riptide. However, the strike was so powerful that it knocked the sword out of my hands.

I pulled out my wand and screamed, "Avada Kedavra."

Because she was a monster, it didn't kill her, but it heavily stunned her.

I picked up Riptide and stabbed her, turning her into gold dust. Then, I sped out of the battle, and onto the docks.

The Golden Trio was already there.

Hermione said, "They're about to finish crossing."

I nodded, "I can't sink them. They're too close to us. I could try, but then, we would be affected too."

As the wind blew his hair into his face, Ron asked, "Then what do we do?"

Harry got in his battle stance and said, "We fight."
