Daughter of Poseidon 2.0. Added a bit tweaks in the story! Enjoy!

"Ha!" I smiled as my sea green eyes look towards Percy fallen state with my wooden sword in his neck

"Yield?"

Percy laughed "Yield sis"

I put my hand out as Percy took it

"What is the points now? 50 to 49?" I boasted to my brother

"Yeah yeah...I'll get you back..." Percy mumbled while walking to Annabeth who's use to this rumble between the two of us already and placing a kiss on her lips. The Giant War just ended and we all have been trying to get everything back to when it use to be. Piper went with Jason, Frank, and Hazel to Camp Jupiter for a while. Leo went to search for Calypso again. Nico went back to the underworld to help uncle Hades. As for me, Percy, and Annabeth we stayed behind to look out for Camp Half-Blood.

Back to the story...

I snorted as I let down my long wavy black hair from my high ponytail into a side braid

"Like now!" Percy said lunging at me only for me to dodge to my right tripping him in the process

"51 to 49" I laughed and gave an high five to Thalia who just arrived with the hunters

"Again?" She asked

I nodded. It's a tradition between me and Percy ever since we're young. A battle of pranks and fighting or anything mostly. The one with the most points at the end of the year can have 3 wished granted from the other person.

"So what's up?" I asked drinking a bottle of water

"Chiron wants you to meet him at the Big House. Something about a quest" Thalia said

Sighing I looked down at my clothes "K, but first let me go back and change" I said

Thalia nodded and gave me a one arm hug before leaving.

I then quickly ran to my cabin and took a quick shower before changing into a pair of black skinny jeans and the camp t-shirt with a pair of black boots and walked out the door heading to the Big House

I walked into the door to see Chiron in his centaur form

"Ah! Ariadne! You have arrived!"

I nodded "So what's up Chiron?" I said sitting down in a chair

"How much do you know about witches and wizards?"

I raised my eyebrows. That's an unexpected question... "They're mortals blessed by Hecate? But what is it gotta do with this?"

"You are assigned to go to a school for witchcraft and wizardry, which was founded by the the first four mortals that was blessed by Hecate and protect a boy named Harry Potter from the Dark Lord"

"The Dark Lord? That weird wizard is too full of himself. 'The Dark Lord'. I highly doubt he's that powerful" I snorted

"Although I have to agree with you on that he's still very powerful so be careful" Chiron said as I nodded

"You'll be leaving today by teleporting to a place called The Burrow. The people that lives there will be expecting you however they don't know who you are. If you can keep your identity a secret"

Then a bright light was emitted in the Big House. The light faded as a women in her 20's appeared in its place. The women had long black hair and matching eyes. She was dressed in a dark robe holding a twin torch

I get on one of my knees and bowed "Lady Hecate"

Hecate smiled and hold me up "Ariadne, no need to bow. I'm here to thank you for accepting my quest. This might be a dangerous one so you must be careful"

I nodded as she touched my head and start to ruffle my hair placing a kiss on my forehead "I hope my blessing will protect you"

I smiled as she then handed me a box. Feeling curious I opened it, inside lay a stick but a really pretty one. It was a silver colored wand with a hint of teal, there was a trident imprinted on the holder.

"Eleven inch elm with the core of Pegasus hair. I got the hair from your Pegasus, hope you like it" Hecate smiled

I smiled back again, then I looked at Chrion. "I'll go and pack my bags" I said and left the room

I packed my clothes and other things into my black backpack that I got from the Hecate cabin. It can fill as much things as I want and it will still feel very light

I then grabbed a pouch full of drachma and threw it into my backpack. I made sure to have my weapon, Asteria. A celestial bronze and iron made straight bladed sword with a shaped edge, with a carved metal handle long enough to be used with one or both hands, the sword's able to configure itself by producing another blade directly from its hilt into an double bladed staff-like weapon, it can also be separated into an pair dual-bladed sword, by splitting it at the central handle. But in human eye it's just a rose gold cuffed bracelet.

By the way I also have telekinesis, I discovered it when I fought the Minotaur with Percy, although it comes in handy a lot I still prefer using my sword. Anyway back to the story, I then put on my black hoodie and walked out the cabin.

I walked with Chiron to the entrance and was greeted by Percy and the others.

"Don't think you would be leaving without saying goodbye would you sis?" Percy smiled

I smiled back "Wouldn't think of it" I said giving him a hug

Annabeth and Thalia walked up giving me some more hugs

"Stay safe Ocean" Annabeth said

"Don't forget to Iris message us" Thalia added

I nodded as I let go of them as Chiron handed me a photo of a hut.

"This is The Burrow. Just picture it in your mind and you can teleport yourself there but be careful first time teleporting can be a bit messy" Chiron warned

I looked up at Chiron "If you told me this a long time ago it would have been really helpful"

Chrion shrugged "You weren't strong enough to learn it yet"

Sighing I looked at the picture as hard as I can and then pictured it in my mind

I then find myself standing in front of a hut that looks exactly like the picture. Surprisingly teleporting isn't as hard as I thought it would be.

The door of the hut then opened and a women stepped out. She was short and a bit plumply, but she has a pair of kind brown shade of eyes with flaming red hair. Very much like mom

"You must be Ariadne, honey. It's nice to meet you" she said placing a kiss on my forehead as well as a hug

I smiled "It's a pleasure to meet you too Mrs?"

"Weasley. Molly Weasley"

"Mrs. Weasley" I repeated

"Now let's meet the rest of the family" she smiled warmly grabbing my arm and gently pulling me in

I followed her inside to a dining table that sat 7 people who was eating. Five of which looked very similar to Mrs. Weasley.

" Mrs. Weasley, who is she?" A girl with slightly bushy brown hair and eyes asked. For some reason she kinda reminds me of Annabeth

"This my dear is Ariadne, she's from America and she'll be attending Hogwarts with you all." said

I laughed in the inside when I heard Hogwarts. 'Pig pimple...I'm going to a school call pig pimples...haha'

I smiled and hold out my hand "Ariadne Jackson. Please to meet you"

The girl smiled back and took my hand "Hermione Granger. Are you really from America?"

I smiled and nodded in reply and sat down next to Hermione after greeting every single person. One of which is the person I was assigned to protect Harry Potter

We soon start to leave as Mrs. Wealsey stayed behind

While we followed Mr. Weasley Hermione, Ginny and I began to talk about Hogwarts so I can get to know it better. I was almost sure that Hermione was a daughter of Athena when she began talking about Hogwarts history

We then arrived near a big tree with a person standing under it

"This is Amos Diggory, everyone. Works with me" Mr. Weasley said

A guy then jumped down from the tree

"And this jumping young man must be Cedric am I right?" Mr. Weasley added

Ginny and Hermione stopped for one second to stare at him then stare at each other. I can't blame them. He's hot.

I continued to walk with them as Harry walked behind us and began talking with Mr. Diggory for a second before catching up

We all walked to the top of a mountain where a old boot stood and stood around it

"Hermione what is this?" I asked

Hermione shrugged until I heard one of the Weasley twin said something about a Portkey?

We all place our finger on it as it began spinning round and round to the top of the sky and a portal thing opened at the bottom

"Let go kids" Mr. Weasley said

"What?" Hermione asked in shock

"Let go!"

Harry was the first one who did it as Hermione and Ron followed and so did the others. I let go after but before Mr. Weasley and the Diggory's landing on my feet as they float/walk down while the others fell down flat on the ground

"How did you do that?" Ron asked

"Do what?" I asked back

"Land on your feet"

I shrugged "It's in my blood"

I hold my hands out for Harry just in time for Cedric to hold out his. Harry looked at both of us and grabbed both our hands as we pulled him up

"Thanks" he said I nodded and walked next to him arriving at a flat land full of tents and some people flying on broomstick?

"Well kids! Welcome to the Quidditch World Cup" Mr. Weasley said

"Hermione, what's Quidditch?" I asked

"You don't know what's Quidditch?" She asked as I shake my head

"It's a wizard sport. You'll see, it's a lot of fun" Harry said

I nodded as we walked through many people and tents until we arrived at one of the small tents that seems way to small to fit all of us. I entered after Harry and see myself standing in a fairly large looking room. I gotta say the Wizards outdone themselves for this.

Hermione dragged me to the room we girls are suppose to share as I put my stuff down on one of the beds.

We waited until it's about night time and walked to a very large stadium

"Blimey dad! How far up are we?" Ron asked

'I hope not to high or else Uncle Zeus will blast me with his lightning bolt if I'm in his territory again'

"Well put it this way! If it rains, you'll be the first to know" I turned around seeing a tall man with long platinum blonde hair and a boy that followed behind. One look and you will know they are related

"Hey Hermione who are they?" I asked

Hermione look at them and snarled "Malfoys. Trust me you don't want to associate with them"

"Father and I are in the ministries box. By personal invitation of Cornelius Fudge himself!" The younger Malfoy I think boasted

"Don't boast Draco" his father I guess said poking him with his cane

'So his named Draco...Dragon in Latin...'

"There's no need with these people"

''Man I hate that man already'

Harry turned Hermione and the other around to leave only to get stopped by Mr. Malfoy

"Do enjoy yourself won't you, while you can" Mr. Malfoy smiled in a disgusted way before letting go and left while I glared not noticing the other Malfoy staring at me

We each got ourselves a things to wear. I got a scarf like Hermione with green and white stripes

"So Ariadne who do you think will win? Irish or Bulgarian?" Harry asked

"It's depends. What players does Irish have?" I asked

"Irish has pretty good players-"

"But Bulgarian has Viktor Krum! He's the team seeker!" Ron cut Harry off

"What's a seeker?"

They all looked at me like I'm crazy "Sorry new to all these things." I said sheepishly

"Seekers catch a small ball we call the Snitch. It's golden and has wings with abnormal fast speed. If the Seeker catch the Snitch it will end the game and the team that the Seeker is on will get 150 points" Hermione explained

I nodded "Well I would cheer for Irish. A group of decent players are more better then one"

Ron huffed "Wanna make a bet?"

I raised my eyebrow and smirked "Winner gets one wish granted by the loser"

"Deal" We both said as we got to the top and the Irish team I think flew past up and fireworks appeared shaping a dancing leprechaun.

I chuckled at the sight of it until the Bulgarian team flew into the leprechaun destroying it and did some acrobats I guess

"That is the best seeker in the world!" Fred or George said as the picture of Viktor Krum appeared on the stadium

"Good Evening!" A guy which Hermione introduce as Cornelius Fudge said with a wand held at his side "As minister for magic, it gives me great pleasure to welcome each and every one of you to the final of the four hundred and twenty second Quidditch World Cup!" He then hold his wand out "Let the match begin!" and a dot of light signal the match

'This is gonna be fun' I smiled

After the match we were back in our tent. Since I won the bet I made Ron dress up as a Leprechaun and then we just sat around looking at Fred and George dance as Ron continue to admire his Viktor Krum

I chuckled and laughed with Hermione. It was a fun day and we all went to bed

"GIRLS! GIRLS! WAKE UP!" Mr. Weasley shouted

I looked up from my pillow "What's going on?" I mumbled

"The Death Eaters" Mr. Weasley says. "We have to head for the Porkey quick!"

I groan and my head fell into the pillow "Who in the Hades would want to eat Thanatos?"

"Ariadne!" Hermione keep on shaking me and smack me with my pillow and does the same to Ginny

I groan and immediately got dressed and shrink my backpack with a trick the Hecate cabin taught me into a key chain to put in my pocket

We got out and everything was chaotic. 'Oh shit! This is actually real. I could put out the fire but there's not enough water! Dammit!'

"Get back to the Portkey everybody and stick together!" Mr. Weasley said

"Fred! George! Ginny's your responsibility! Go!"

"Harry let's go" I said as I grabbed him and ran with Hermione. People were running and screaming away from the fire

"Harry!" I screamed as he get pushed away from me by the crowd

I began to run his direction until Hermione grabbed me "Ariadne! Let's go!" as we get farther away from Harry

"Everybody all right?" Mr. Weasley asked once we all got to a safe place

I look around nervously "Harry's not here!"

"We have to find him!" Hermione said as we began to run back with Ron behind us

When we arrived everything was burnt to ashes.

"Harry! Where are you?" Ron shouted

"Harry!" Me and Hermione yelled until we saw him and ran over

"Been looking for you for ages. Thought we lost you man" Ron said as me and Hermione check if he's hurt

We then look up the sky "What is that?" I asked it was a huge skeleton with a snake coming out its mouth while Harry's scar began to hurt

People then surrounded us "Stupefy" they shouted at once aiming at us

"Stop! That's my son! Ron! Harry! Hermione! Ariadne! Are you all right?" Mr. Weasley said running to us as we stood up nodding

"Which of you did it? You've been discovered at the scene of crime!" A man said pointing his wand at us

"They're just kids!" Mr. Weasley said

"What crime?" Harry asked as the man lift up Harry's hair with his wand seeing the scar

"It's the dark mark Harry!" Hermione whispered

"Voldemort?" Harry asked

"Voldemort?" I snorted "That's a funny name. As well as Death Eaters...They got to stop making such ridiculous names"

Everyone turned to me like I'm crazy "What? It's just a name, funny one as well if you ask me" I said as Hermione elbowed me "okay okay I'll stop"

"It's the Death Eaters" Mr. Weasley said

The man turned around to his crew "Follow me!"

Harry stepped up "Um, there was a man, before! There!" He said pointing at the direction he was looking at a while ago

"All of you! This way!" The man said walking away

"A man, Harry. Who?" Mr. Weasley asked

Harry turned back "I don't know. I didn't see his face"

I turned to Hermione who was shaking as I gave her a hug and we all look up at the sky seeing the skeleton with the snake in the sky

So that's all for chapter 1! Hope you guys enjoyed it!

P.S. I change some things so that the plot won't be so complicated later on :)
