Unexpected Allies

Harry's POV: _

When I woke up It was around 10 o'clock in the morning and I was still tired, but I still wanted to do something so as to not waste the day away. Deciding to make Hermione proud of me I figured it wouldn't hurt to take a glance at some of the books before the start of the term. I went to grab the Care of the Magical Creatures book, that looked odd with a belt around the book keeping it close.

I undid the buckle only for the book to then suddenly grow eyes, I looked at the book amazed before it started chomping and trying to eat me. I dropped the book and the mental thing went for my feet, I ran for the bed jumping on it which thankfully the book couldn't instead it just slid under the bed.

I peeked underneath to see if it was still there, and it was but it started to chomp towards me again, so I pulled myself back up only to have the thing slither back underneath the bed. I came up with a plan and untied my shoe before throwing it in front of the bed. The book as expected immediately went to it and started to chomp down on my shoe. So, I jumped on the book satisfied that my weight seemed to knock it out.

When I looked up Hedwig was just staring at me like. "Are you done yet? I'm hungry."

I shook my head before grabbing the belt and locking it up tight around the book, whoever our teacher for Care of Magical Creatures was, they were absolutely mental. Deciding that the universe didn't want me to study I gave Hedwig a treat before going downstairs hoping I could get some food from Tom.

As I was getting ready to make my way down the stairs to the bar, two people walked in both looked to be about 17. Normally I wouldn't care all that much, but they looked out of place. First their clothes looked a lot like muggle clothes and they had suitcases with them. Second, they were looking everywhere, like they weren't really sure if they were in the right place or not. I figured they were a random couple that walked in here by accident, considering they were kind of looking at all the magic going on in the room in awe.

The boy was tall probably a little over 6 feet and he looked like a Greek god, with clearly defined muscles and a face that looked like it was carved from marble. The girl however was stunningly beautiful, she had blonde curly hair that reminded me of princess curls, with high cheekbones, and an angular face.

Both of them were tanned like they just came from a year long stay in the Mediterranean, however when the boy looked up at me and we locked eyes I was shocked, his eyes actually looked like the sea with untold power in them. He nudged the girl and she looked at me as well and her eyes were a stunning grey that made her look incredibly intimidating, and all the more beautiful.

I noticed their intertwined hands and figured they were a couple. I was about to introduce myself when none other than Dumbledore beat me too it. I didn't realize Dumbledore was here, the three of them conversed for a while and I started to make my way to the bar to ask Tom for some food. Right as I sat down however Dumbledore tapped me on the shoulder.

"Hello Harry, I heard about the unfortunate incident with your aunt. How are you doing?"

I looked at Dumbledore and noticed that the two-other people were standing behind him kind of awkwardly like they didn't know what to do.

"I'm good professor, if you don't mind me asking who the two people behind you are?"

"Oh, yes these are just two new faculty I have decided to add this year to help around the castle. Harry meet Perseus Jackson, and Annabeth Chase."

The boy nodded his head and stuck out his hand. "You can call me Percy."

I grabbed his hand and already decided he would be better than Percy Weasley, he had that troublemaker grin and a certain glint in his eye. The girl then stuck out her hand as well.

"Nice to meet you Harry, I'm Annabeth."

I shook her hand as well, they both were from America they had a strong accent. Dumbledore patted me on the shoulder.

"Well we must be off Harry, much to do. I look forward to seeing you at the feast this year. Oh, and I heard that Miss Granger, and the Weasley family will be here a bit later."

With that the three of them walked towards the back exit, and towards the entrance to Diagon Alley. The two of them seemed like nice people, especially that Percy fellow. I hoped they would be nice teachers like Hagrid, and nothing like Snape or Filch. It wasn't until later that night when I was lying in bed that it dawned on me they didn't already know who I was or stare openly at my scar.

Annabeth POV: _

The flight over was long and tiring, I now understood what people were talking about when they talked about jet lag. Thankfully Percy slept through most of the flight, so my hand wasn't broken by the time we landed. Once we were out in baggage claim Percy grabbed two bags while I grabbed the other. The only thing Hecate told us to do when we got here was to go to a pub called the Leaky Cauldron.

So, Percy walked outside, and in his best New York fashion whistled down a taxi. Once we put our stuff in the trunk we climbed in the backseat, I gave him the address to the Leaky Cauldron which Hecate had thankfully given me as we left knowing Percy would have lost it. Percy looked at me a little confused and I just whispered Hecate and he nodded before looking out the window, intertwining our fingers. I smiled before looking outside my window as well admiring the Architecture.

It was a long and silent car ride once we arrived Percy grabbed two bags and I grabbed the other one and we made our way inside. Now it's one thing to be told magic is real, it's a completely other thing to see it in person, and I was in shock. I glanced at Percy and saw he felt the same way.

After a second, I felt someone staring at us, but before I could find who it was Percy nudged me towards the stairs and I saw a boy who looked about 13 or 14 and reminded me a lot of Percy when we were younger. Scrawny, with unruly black hair, and green eyes not a sea green though. Suddenly an old man was in front of us.

"Hello, I am Albus Dumbledore, are you two by chance from America?"

We nodded our head, remembering Hecate mention his name Percy spoke up.

"Yes, you are the headmaster right, of Hogwarts? Hecate sent us"

Dumbledore smiled kindly like that of Chiron. "Yes, I am the headmaster, what is your names?"

I stuck out my hand. "I am Annabeth Chase, and this is Perseus Jackson, but call him Percy."

Dumbledore smiled at us, we talked for a while about the magical world and what all we should expect. Eventually we got around to the person we were to help protect, Harry Potter. When Dumbledore mentioned what he looked like, I remembered the boy on the stairs. When I said this Dumbledore looked grim as though Harry Potter shouldn't be here and somewhere else.

At our looks of curiosity Dumbledore talked about how there was protections around Harry's house with his aunt, that made him much safer than anywhere else. At that Dumbledore looked around and noticed him just sitting down at the bar. I thought it was odd that a 13-year-old would be at a bar, but I didn't feel it was my place to say anything.

Dumbledore introduced us, and we got to talking for a while before we were off to Diagon Alley. After walking out the back door we were at a brick wall. I was confused, and I could tell that Percy was too, before we could say anything Dumbledore touched a number of bricks in a certain order and the wall slowly disappeared to reveal what I believed to be Diagon Alley.

Now as someone who has seen and helped redesign Olympus I can say that while Diagon Alley was not up to that level it was truly magical. Everyone was wearing robes and some witches were wearing hats. However, most people stopped to wave and say hi to Dumbledore. Which got me to thinking that he must be a prominent member of wizard society. I also realized we didn't know much about the magical world other than the defensive spells and other basic spells which she blessed us with.

"Headmaster, I was wondering what is this world like? Our benefactor only taught us a basic spell, as well as defensive spells, but we do not know much besides that. Would you care to fill us in?"

Dumbledore looked at me and I could see a twinkle in his eye, similar to that of Chiron.

"Yes, my dear, I suppose that would be beneficial come Floreans's ice cream is right around the corner."

After walking a little way, we came across, and passing all sorts of interesting and cool looking stores, we came to a nice little ice cream parlor. And which the second we sat down a woman came and immediately welcomed Dumbledore. They chatted for a second before she asked what we all wanted, when Percy and I said we didn't have any money the woman shook it off and said if we were here with Albus then we wouldn't need worry.

Albus apparently got his usual, I got a strawberry sundae, while Percy got blueberry. A second later the ice cream appeared, and we got to talking about the magical world. Some of the most important things that Albus mentioned was that of the Ministry of Magic, as well as that of some evil creatures called Dementors that Dumbledore said he was forced to have around the school for the year. He also told us the spell we would need to deter them "Expecto Patronum" Which I instantly knew how to do thanks to Hecate.

He told us that they were there to protect Harry from Sirius Black and what happened to cause Sirius Black to go after Harry Potter to begin with. Although Dumbledore did say he had some doubts that Sirius would betray his friends as such. It is why he wanted to talk to Sirius before the Ministry or Dementors found him.

After much talking I had a better understanding of the Magical world and how to blend in better and I saw Percy understood a lot more as well. Dumbledore looked at us with that same twinkle waiting for more questions, he had been explaining things for almost an hour. When we didn't say anything, he spoke up.

"If that is all your questions, we should go to Gringotts the most prominent bank here in the wizarding world, after which sadly I must depart. but I trust you both will have no problems exploring and finding what you need on your own."

We nodded our heads and Dumbledore lead us to a great white marble building that towered over all of the other shops in Diagon Alley. It was quite intimidating if I hadn't seen Olympus before. White steps lead up to two giant bronze doors, where two small creatures stood guard in a uniform of scarlet and gold. Dumbledore nodded his head at them and they did in turn only to look at us and stare with a face of disbelief before quickly concealing it. We walked to the bronze doors into an entrance hall that held two silver doors which presumably lead to the lobby guarded by another two goblins, both staring at Percy and I in shock.

There were words written on the two silver doors however that with the cursive writing was almost impossible to read. After looking at it for several seconds though I began to piece together what it said.

Enter, stranger, but take heed

Of what awaits the sin of greed

For those who take, but do not earn,

Must pay most dearly in their turn.

So if you seek beneath our floors

A treasure that was never yours,

Thief, you have been warned, beware

Of finding more than treasure there.

Before we walked with the ominous warning on the doors Dumbledore stopped us.

"Before we go in I want to inform you that Gringotts is operated by goblins who are very greedy wizards, and do not like wizards very much. They don't like being stared at."

Percy and I quickly said "okay" before we continued on into Gringotts. Once inside the silver doors all the goblins stopped and turned to look at Percy and I for what felt like a split second before continuing back to what they were doing, it was quite eerie. Dumbledore either not noticing or not caring about the weird reaction continued forward to one of the teller stands where he waited for us patiently.

"Now Hogwarts can provide you two with the necessary funds to start here just tell the clerk you are the new groundskeepers of Hogwarts and need your first paycheck in an advancement. Now I must be off good luck."

With that he was off, back towards the entrance. Percy and I slowly made our way up to the one of the tellers who quickly gave what seemed to be a smile of satisfaction to the other goblins before turning to look at us.

"Welcome to Gringotts what can I do for you?"

Percy spoke up for us. "Uhh well we are the new groundskeepers of Hogwarts and would like to take or first paycheck as an advancement, we also have some American money if we can convert that here."

The goblin looked at us puzzled. "Are you two not Perseus Jackson and Annabeth Chase?"

At the mention of Percy's full name, I could tell he was on edge, as was I. Not only did they use his full name, they also knew both our names without us telling them. I spoke up this time.

"And how might you know this?"

The goblin smirked at us before talking. "Unlike those pathetic wizards who think they are above everything else most other creatures here know that there are higher powers not to be trifled with, and we here at Gringotts are no fools. Come your kind has special vaults, also these were given to us by The Rich One for you two."

The goblin handed us each a small leather pouch mine was leather with a great grey owl on the front outlined in gold with diamond encrusted eyes. In the corner of the pouch was a dark helm and I knew this was a gift from Hades. I looked at Percy's pouch and saw that it was leather like mine but had a great black Pegasus on the front outlined in gold, with sea green gyms for eyes, and sea green gems studded into the wings making them sparkle. In the corner was again the Helm of Darkness the telltale signs it was from Hades. Deciding I would remind Percy to sacrifice some food to the Lord of the Underworld later we followed the goblin towards presumably our vaults.

While we were walking the goblin mentioned that the pouches had been enchanted to hold an infinite amount of gold and cash, and if needed could produce money of any currency minus that of wizards. I grabbed Percy's hand when I noticed we were going into a mining shaft. While Hades was much nicer to Percy then Zeus, the gifts speak of that, I also knew it was in his D.N.A to fear tight underground spaces just as he fears being in the air. He gave me a small smile and we continued walking a couple more feet before coming to a mine cart.

The goblin quickly got in followed by Percy and myself, before pulling a lever and we were off into the mine at breakneck speeds. Had I not been a demigod I was pretty sure I would have died from the extreme G forces we received going down into the dimly lit cave. Once we stopped I had a hard time keeping my lunch down, and I could see Percy was a sickly shade of green as well.

The goblin got of the cart patiently waiting for us to get our bearings. When I finally felt like I could look up without puking I noticed we were in a cavern that had a single vault door made of what seemed to be imperial gold, with two torches emblazoned on top, the symbol of Hecate, along with two torches on either side of the vault that came alive with Greek fire when Percy and I stepped forward.

"The goddess Hecate is the only vault the Gringotts holds for the gods of Mount Olympus, for the sole reason that mostly it is only her demigod children that visit the wizarding world. It is the also the only vault that we goblins do not know much of what is inside, in fear of provoking the goddess's wrath."

It made sense, so Percy and I walked up to the vault, where Percy slowly put his hand up to the door that began to creak and turn as it was opened. Inside there was mounds of wizard currency along with Drachmas, as well as swords, shields, and armor of the most intricate design. I realized however that Percy and I had no idea about the wizard currency. So, as I turned around to ask the goblin I noticed a piece of paper on the back of the vault that explained the value of a galleon to sickle to knut and the conversions. I was thankful, I didn't want to seem like a complete idiot. Percy and I quickly grab quite a lot of money having no idea how much everything might cost before deciding to look around the grand vault for a minute.

Which sadly one of the most interesting things we found was a wand in a box that belonged to some Merlin guy. Deciding we explored enough we returned to our goblin friend.

"Did you both get all that you need?"

We nodded our heads and the goblin hopped in the cart. "Then come on then."

After getting in the cart and bracing myself against Percy who looked just as unwary about the idea of getting back through the metal death trap or mining cart. Then we were off at breakneck speeds back to Gringotts.

After finally leaving the goblin bank with a decent amount of the wizard currency Percy and I decided to explore a little bit. Everywhere we walked however there seemed to be a poster of the Sirius Black we were supposed to protect Harry from. We had a silent agreement to try and bring him to Dumbledore before the Dementors gave him a kiss, because it sounded horrible.

The first shop we came across was Madam Malkin's Robes for all occasions. After many promises and a threat, I convinced Percy that we needed to get at least a few robes, so we don't stick out like sore thumbs.

We walked in side where a nice woman was waiting behind the counter.

"Hello how are you two today, what can I help you with?"

"Hi, we are from America and just wanted to get a few professor robes for Hogwarts, as well as a set of dress robes."

The woman nodded kindly before grabbing some different sizes robes and handing them to us and showing us a dressing room. After trying on the ones, she gave us and walking out to her, where she used magical tape measures, and making marks on the robes to get the perfect fit. She then told us to come back later in the day and the robes would be ready. I had ended up getting a grey dress robe, while Percy got sea-green, on top of the black Hogwarts teacher robes.

After leaving Madam Malkins we went into a shop next door where they sold quills. After seeing a few that had enchantments on them that we had no idea what they did Percy and I just bought some regular quills before moving on.

We passed by a store called Broomstixs and after walking in and seeing that the broomsticks was a type of flying Percy promptly dragged me out. Then we made our way to a place called Eyelops Owl Emporium, the second we walked in the door all the owls in the area stared at Percy like he was Gaea. Then at once the voices bombarded me.

"What is that Sea-spawn doing here."

"Let's kill him Lady Athena shall reward us"

"No, Phillip Poseidon would most surely seek revenge."

"Let's shit on him."

I grinned at that one, before talking back to them.

"No, I ask that all of you don't harm my boyfriend please."

At once they seemed to realize that I was a daughter of Athena. And immediately I heard a flurry of yes m-lady's before they all went back to what they were doing beforehand. Percy and I walked around a bit and I started to get a headache from all the voices in my head. Percy reached forward to grab my shoulder to provide some sort of comfort when a owl literally pooped on his head and I had a sneaking suspicion it was Phillip.

Percy groaned, before asking the clerk at the counter where the bathroom was. Who after imploring that he was sorry for the owl's behavior, and that they usually didn't do anything along that line told him it was in the back. While Percy was cleaning the crap out of his hair, I found a beautiful Great Grey Owl who told me his name was Carmine.

I went to the Clerk before paying for the owl as well as buying some treats for him. Percy came out shortly after with slightly damp hair. I gave him a kiss for coming with me before grabbing Carmine's cage and handing Percy his treats so that they could build a healthy relationship before making our way out the store.

Carmine however stayed quiet about Percy, so I took it as a win. The next store we saw was Flourish & Blotts, after taking detour inside and I saw it was full of books about the wizarding world. We spent nearly an hour inside while I grabbed a lot of books about the wizards and a few on some basic spells. Percy found some about wizard wars, as well as potion making, which I recommended because I thought it might be something Percy wants to work on in his spare time.

We left the bookstore weighed down by all of the books we were carrying, I suggested we go get our wands and drop some stuff off in our room at the Leaky Cauldron Carmine hooted in response. Dumbledore had said a room would be given to us from Hogwarts, and we would ride up with the students on the train. Percy and I walked up to Ollivanders before Percy opened the door like a gentleman before following me inside.

It was quite a dusty and cluttered place. Nothing like I expected, considering this is the best place to get your wand. The sole source of a wizard's power. A quaint old man with wide pale eyes immediately sparked with light when he saw us.

"Hello, Hello, come in, come in. How can I help you?"

Percy spoke up. "Hello sir, we are from America who came due to a job opening at Hogwarts, we were curious if we could each get wands? Ours were destroyed in America."

"Ah I see, well let's get to work then. Hold out your wand arm."

Just like Madam Malkins magical tape measures began to measure everything about Percy's arm. Ollivander hummed in response before walking through the cluttered shelves and using his wand to float a multitude of dusty boxes and bringing them back out.

"Blackthorn, ten & a half inches, unyielding, unicorn hair."

Percy grabbed the wand but looked dumbfounded on what to do. Ollivander thankfully seemed to understand before saying.

"Come on now, give it a wave."

Percy went to wave the wand however the second he did a small crack appeared on the wood and a bright light was seen inside. Ollivander quickly grabbed the wand out of his hand.

"My god boy, you have some powerful magic inside you. Try this one. Black Walnut, ten inches, unyielding, Unicorn Hair."

When Percy went to wave this wand, it actually nearly exploded with multiple cracks coming along the wood. Ollivander hummed in thoughtfully as he gave him wand after wand, some were better, in the sense they didn't crack. Others however were not as fortunate. After going through the last wand Ollivander brought out which ended with some strong shaking in his hand before flying itself into the box.

Ollivander hummed in excitement before going back through the many rows and shelves. Percy spoke up.

"I am sorry sir I am not sure what is happening."

Ollivander practically laughed. "No, no, no, my dear boy. You are giving me the best experience since I have started selling wands I am quite excited to find one that will match you. I have an idea.

Ollivander came back with a black box, however when he pulled out the wand it was a beautiful golden color that seemed to emit happiness and strength.

"English Oak, 11 inches, unyielding, Unicorn Hair."

When Percy waved this wand, there was a shockwave throughout the entire building like a small earthquake, followed by the scent of the ocean throughout the entire shop. The wand also seemed to gain a glow, and was now almost radiating strength and comfort, like a friend you could always count on no matter what. He looked at Ollivander dumbfounded.

"I believe we have found you a wand my boy. That wand is the first of its kind, extremely loyal due to the combination of the English Oak and Unicorn Hair. The power in that wand is only imaginable the power of your magic along with the loyalty in the wand in itself means not much has reached this wands potential."

Ollivander turned to me, and I was suddenly a bit more anxious. With the time and struggle to find Percy a wand I hoped I wouldn't be as difficult.

"Now you, hold out your wand arm."

The process repeated with the magical tape measures measuring every part of my arm before Ollivander waved it off, going to the back and coming back with a handful of boxes.

"Here try this one dear. Blackthorn, 10 inches, flexible, Phoenix Feather."

I waved the wand for a small fissure to appear along the side before Ollivander snatched it back.

"Oh, both of you are quite powerful, this is most exciting. Cypress, 9 & half inches, unyielding, Phoenix Feather."

The wand shot a single spark before Ollivander grabbed it from my hand and handing me another.

"Hornbeam, 10 inches, sturdy, Dragon Heartstring."

When I waved this wand, nothing happened but Ollivander seemed to like the results because he smiled before putting the wand back in the box before going to the back of the store coming back with a singular grey box.

"I believe this will be the wand for you my girl."

He pulled the wand out of the box and handed to me a beautiful dark brown wand that gave off an air of knowledge.

"Walnut, 10 inches, unyielding, Phoenix Feather."

I waved the wand for the books Percy and I bought along with a few in Ollivanders shop fly to me, followed by the sound of Carmine hooting joyfully. My wand also began to emanate a sense of wisdom and thirst for knowledge. I looked at Ollivander and smiled at him gratefully.

"How much do we owe you for the wands sir?"

"7 galleons each please, it was a great pleasure finding the two of you new wands thank you."

We paid him smiling before walking out the door with our wands in our hands. I tugged Percy back to Madam Malkins and told him we might as well put our robes in our room as well Ollivanders took a while, so I imagined our robes would be ready It was about mid-day so if we hurried we could check out a few more shops before getting dinner.

After dropping everything off in our room Percy and I went to Wiseacre's Wizarding Equipment. Because I did not like the idea of carrying our fragile wands in our back pockets, and this was the place that Tom the barkeep said would have something to help with that.

When Percy and I walked in we saw a whole range of various things inside that we had no idea what they did. But they had some things we knew like telescopes, after browsing for quite a while we found some wand holsters. We bought two before making our way back outside. After attaching my holster to my waist at the same time Percy did I looked and saw Harry along with two other kids head into a shop called Magical Menagerie. I figured becoming friends with the kids would be the best way to protect them so nudged Percy before following them inside the store.
