Sorry for not updating in a while, I have been busy.

Let's just get in to the story, but like all others we need to do the disclaimer first.

So who wants to do it/

"I DO, I DO, LET ME DO IT."

What the hell are you doing here, Deadpool, this is not even your universe.

"I always wanted to do a disclaimer so I thought I'd come here."

Since I know I can't kill you in any way, I seen you turned into a pile of mush and you still came back from it you can do the disclaimer.

"YAY, this person (seriously who is this guy?) doesn't own PJO, HOO, or HP. Whatever they are?"

Now you can leave Deadpool,

"I don't wanna"

LEAVE

"NO"

That's it Stan get in here.

"Don't call Mr. Lee"

"How did I get here?"

Sorry Mr. Lee, (slight swoon) can you get Deadpool to get out of here?

"No guarantees"

Know what screw this, *snaps* now that they're gone we can get

"What you do?"

Gods Damn it, I would throw you into Tartarus but you would enjoy it so I am just going to ignore you.

So let's get on with this story.

Harry POV:

That was weird what happened in Herbology, those plants seemed to be drawn to Percy and Annabeth. That made for an interesting class to say the least but in the words of Ron, I am glad classes are over I am bloody hungry. So I headed to the great hall.

Halfway up to the castle Ron, and Hermione stop me. Ron saying "That was bloody weird, I mean first he finished a potion that should take six months in one double of potions. Then the planets that would oonly bloom till Valentine's Day, grew and bloomed in one day."

"I know, then theirs Annabeth," Hermione continued "She just seems to analyze your every move, that doesn't seem normal."

"I heard that something similar happened Piper during Hufflepuff's Herbology class."

"And some of the other things I heard, all the ghost seem to be afraid of Nico."

"Yeah, and Annabeth didn't come back to bed last night after that freak earthquake."

"Did you notice how they seemed to cling to each other, as if they are the only thing keeping them alive. And that some of them have tattoos on their arms, I bet it's the dark mark and they are death eaters."

This continued on for a good couple of minutes, when I finally got time to say something "Well we should start keeping an eye on them."

By the time we finally agreed to keep tabs on them, Hermione would did a spell that would instantly write down anything we thought was weird. It was kind of like the floating quill and parchment that followed Reeta Seekter around.

We sat down and when the food appeared in front of us we started eating then we say that they were burning food again, so we added that to the list.

Half way through the meal Dumbledore got a look on his face that said something was wrong, he got up and walked over the exchanged students and started talking to them, but not in English. He was speaking the same language that Binns did when he saw Nico.

Percy got a stern look on his face, stood up and looked over to the Hufflepuff where the other exchange students where, they had a look like they were just given orders from their commander.

They stood up and followed Percy and Annabeth out of the Castle, Dumbledore walked out, but he took a weird path so that he would pass by us. Something seemed to fall out of his cloak as he passed us.

Curiously I looked down to see that it was a cloak, more specifically my cloak of invisibility. Dumbledore had this look in his eyes that said I know you want to know more so follow them.

So Hermione, Ron, and I excused ourselves by saying we wanted to get some head start on studying for the OWLS, people gave weird looks to Ron. But they just assumed Hermione was just forcing us to study, because that was usually happens when there is a big test.

Once we got out of the Great Hall, we threw on the cloak and followed the exchange students out to the lake. They walked with a confident gait, Percy in the front, with Annabeth, Jason, and Renya slightly trailing, followed by Thalia. Frank, Hazel, Leo, Nico, and Piper. Once again they were talking in that other language.

Once we reached the edge of the lake and the forest, Percy turned to everyone and looked to Annabeth who gave everyone the look that said "you know what to do go".

With that Percy dove straight into the lake, Jason spread his wings and flew off. Frank turned into a bloodhound and started sniffing around. Hazel put her hand to the ground and started to concentrate. Piper pulled out a mirror, no it was a dagger. Nico and Thalia ran into the forbidden forest, Nico straight into shadows, Thalia running between the trees, the leaves didn't even move under her feet.

Annabeth was just standing there, so we inched closer, she seemed to be lost in thought. After a while everyone seemed to return, Percy said "The mer-people haven't seen anything and neither has Kali"

Annabeth gave him a questioning look, "The giant squid, its short for Kalamari, don't ask that is what he said his name is." He wrapped his arms around her and nuzzled into her neck, Hazel stood up and Piper stopped looking in the mirror. Hazel started to fan her face, Piper had a sly grin and coughed to get their attention. Percy just stayed in her hair and neck, not even acknowledging that they are there. Jason landed next to them, a cheetah came running out of the forest that turned into Frank. Wasn't he just a blood hound?

Thalia slipped out of the forest again without disturbing any leaves, and Nico slipped out of the shadows. Hazel said "I can't say what it is but it slithers against the ground."

Piper said "I couldn't see but when I looked into its eyes I couldn't move."

Jason added "From the bird's eye view it looked like a snake…"

Frank butted a little confused "It smelled like a dragon"

"It left a solid trail like it had no legs, and Percy there are things in the forest you have to see."

Lastly Nico added "It was about thirty feet long."

Annabeth had a serious look on her face "It is probably a Drakon, more specifically an Aethiopian Drakon. Sounds full grown, did anyone find out if it spits fire or acid." She said all this like it was a normal everyday occurrence for it. The entire time just stroking Percy's hair. He whispered something in her ear that sounded like Damasen. Whatever that was.

Then something weird happened the lake start to churn. Like how the ocean did the Hagrid came to take me to Hogwarts. Like a storm was coming and this was going to destroy anything in its path.

"So, Jason, Nico do know where it is? Or where it is heading?"

"Last I saw it is in a clearing in a forest heading straight towards Hogwarts. I think it will be here in about 15 minutes."

Annabeth had a serious look on her face once again, her gray eyes swirling like clouds in a storm. She slowly pushed Percy off her shoulder, turned to everyone and said "Nico, take Thalia and Frank to the clearing. Thalia, Frank hide in the trees, and aim for the eyes, while that is happening Nico return for Piper and Hazel. Once there Hazel create a wall of stone so it can't get any closer, Piper charmspeak it to confuse it. Nico summon the undead to try and hold it off. Jason start flying towards it try and hit it with lightning. When Percy, Leo, and I get to the clearing we will try to get it from behind. Everyone get that?"

She took the silence as understanding then Jason spread his wings once again and started to fly towards the forest, Nico grabbed Frank and Thalia and ran into the shadows. Percy and Annabeth ran into the forest, so we followed them.

If it wasn't for Hermione tracking charm, and Leo being slightly slower we would of lost them, how were they in such good shape, I had no idea. I think also trying to hide under the cloak at the same time made it harder. When we reached the clearing in the middle was something that looked like a 30 foot long snake like creature. It looked somewhat like the basilisk I faced in my second year. But older, deadlier and mixed a dragon from the Triwizard tournament.

One eye had arrows protruding from it, and when I looked into the other one I couldn't move, I was paralyzed. I heard it speak, in my head, some words I didn't understand, it sounded hypnotized, it said "destroy Hogwarts"

All of a sudden arrows came flying out of the forest one hit this monster, what did Annabeth call it a Drakon in the eye. It roared in rage, if the eyes didn't paralyze me the roar would have. The Snake like creature lunged towards a tree and caught it in its mouth.

It ripped the tree out of the ground, this tree was bigger than the snake, there was a loud crack. And the monster crushed the tree in its jaws as if it was a tooth pick. Splinters flew everywhere, the earth shook and a wall of stone, and gems blocked not only the monster but everyone in the clearing. The earth split and skeletal hands reached out. An army of skeletons came out of the ground, who rushed towards the monster.

The monster sweeps its tail against the skeletons, some burst others grabbed on trying to pin it down.

"Better late than never death breath."

Piper turned and yelled "SIT. ROLL OVER. PLAY DEAD." And other commands one would yell at a pet. The monster looked confused, and Ron actually attempted some of the commands piper was yelling.

A lightning bolt flew down and struck the creature, the skeletons exploded, and the snake like creature became stiff.

"Quick while its stunned!"

All of them rushed the monster, Jason dive bombing cladding himself in lightning, Nico running forward with shadows wrapping around him. Hazel raising her hands and some of the earth wall floating up. Leo pulling a hammer out of his belt and lighting himself on fire. Piper pulling out a Capricorn?

Frank changed into a giant dragon bigger than the Hungarian horntail, Thalia flipped out of a tree landed pulled out a silver bow and arrow. Lightning struck her, if Hermione didn't already have her hand on her mouth she would have screamed.

But Thalia was perfectly fine, you could see the electricity being concentrated into the tip of the arrow. We looked to Annabeth but she just pulled out a sword that looked like it was made of ivory. But the reaction from the monster (what Annabeth call it a drakon?) was what scared us. It squirmed trying to move, like it was trying to run away.

Percy had his own personal hurricane, unlike the others his eyes were glowing an eerie sea-green. Jason was the first to hit the drakon, a loud crack of thunder happened when he hit. As Leo ran forward dragon Frank leaned behind him and breathed fire on him. Leo took the extra fire and wrapped it around his hammer and smashed into the side of the drakon. A pillar of flame shot up scorching the earth, and melting his robes.

Thalia let loose her arrow which turned into a lightning bolt that struck the beast between the eyes, Piper held up the Capricorn and sent food flying at it causing it to be more disoriented. Annabeth ran forward and brought the blade down in between the beast's eyes. Hazel brought down her hands causing the earth to smash into the monster, what didn't hit it trapped it. The entire time Nico slipping in and out of shadows slashing and hacking at it. Then Percy jumped up in to the air, the hurricane turning into a cyclone concentrating around his bat, no wait that is a sword. When he brought it down, a whirlwinds spun up from inside the rock formation, what looked like gold sand mixed in.

Percy climbed out virtually unharmed by that storm, like the others he had scratches and bruises but that was from fighting the actual monster. Percy stood like a general who just led his troops to victory.

I expected them to just collapse from exhaustion, I mean I was exhausted and I just watched them fight. Percy turned to Leo and started giggling, I was half right but not from exhaustion but from laughter. When I looked at Leo, he was pretty much almost naked, but his Shark-boy and Lava-girl under wear were somehow still intact.

After a couple of minutes they picked themselves up and looked like they were about to head to the castle till Nico ran up to Annabeth and whispered something in her ear.

She turned straight at us and said "I know you guys are there, so come out."

We didn't do anything so she turned to Piper who said "Come out now."

I do not know why but we pulled off the cloak and just stood their eye to eye with these inhumanly powerful exchange students.

Annabeth said "Let's go, you want an explanation and we need to talk to Dumbledore."

And adding as an afterthought "And Leo needs to get changed."

That is it for this chapter.

Until next time

The king of Hades.
