Hey Everyone, I'm back with a whole new story. I have got back into Fanfiction and I started reading some PJO and Harry Potter crossovers. While there are a few good ones, most of them base themselves around the demigods going to Hogwarts to learn/teach and while that's a good concept I decided to throw it out the window. For that reason, I would like you all to keep in mind that the story will start at the Prisoner of Azkaban for Harry, But after Blood of Olympus for PJO. With that in mind enjoy and tell me what you all think by leaving a review. I will be sure to answer some in the next chapter.

I do not own PJO or Harry Potter

Unexpected Allies

Albus Dumbledore sighed heavily, his brow creasing and fingers massaging his temple. Cornelius Fudge was starting to get on his nerves. Ever since Sirius Black escaped from Azkaban Cornelius was ever insistent on adding Dementors to the Hogwarts grounds. Something that Albus would not stand for while he was Headmaster. The Dementors were rouge creatures that held allegiance to no one, except for Tom Riddle. Cornelius was a fool for thinking that he could control the evil creatures. Dumbledore's musing went unnoticed by the Minister's head in the fire, and slowly Albus brought his ears back to attention.

"-hat is why Dementors need to be added to the grounds Albus, Harry's life is at stake here. Black wants him dead for revenge against He-Who-Must-Not-Be-Named. You know that better than anyone."

Dumbledore sighed again for what felt like the umpteenth time today.

"Cornelius, you know how I feel about the Dementors, they have no place in a prison. Let alone a school full of children, I will not have those foul creatures anywhere near Hogwarts. It's bad enough that you are stationing them in Hogsmeade."

Cornelius rolled his eyes, as much as a head in fire could.

"Dumbledore, you best know they are the only thing that could possibly keep Black from Harry."

Dumbledore masked his emotions, trying not to show the Minister how annoyed he had become with what seemed like the 12th conversation they had about the same issue since Black escaped from Azkaban. And with the school term right around the corner, Dumbledore felt that he would receive a many more calls.

"Cornelius, if the Dementors couldn't keep Black locked in his prison, how do you expect them to keep Black from coming to the school grounds for Harry?"

Cornelius had opened his mouth to speak, however Albus cut him off.

"I understand your fear Cornelius, but I trust in the wards, and staff around Hogwarts to keep its students safe. I will not have Dementors running amuck on the school grounds. Now I have a staff meeting to commence, so that I can brief the faculty on how to handle Black should he show up. So, if you would excuse me."

Dumbledore stood up signaling the end of the conversation Fudge having stayed quiet for a minute, finally decided to speak up, dropping the conversation on the Dementors. Only a fool however would have thought that would be the last time they talked about the issue, and Albus Dumbledore was no fool.

"Very well Albus, I will contact you later this week to go over some other issues, Good day."

With that the head in the fire disappeared, Dumbledore's face looking older than ever. And it was in that moment that Albus Dumbledore received a miracle from the gods. There was a bright flash in the room forcing Dumbledore to shield his eyes. However, when he looked to the source of the light he saw a beautiful woman.

The woman was dressed in white robes with ornate silver designs. The designs reminded Albus of runes almost, but these 'runes' seemed to hum with power untold. The woman had almost midnight black hair, that barely reached her shoulders. A green aura surrounded her making her seem more intimidating. Her face was Greek like, pale, sharp, and fierce.

Dumbledore gazed at this woman not daring to move, he doubted he could possibly even bring is wand up before he died by this woman's hands. He didn't know how, but she somehow got through the wards surrounding Hogwarts and into to his own personal office. It was simply unheard of unless you were the Headmaster/mistress of the school. Suddenly all the portraits behind Albus started coming alive staring at the woman as well.

It happened at once almost that the previous Heads of Hogwarts shouted. Demanding to know how she got in here and who she was, the woman looked at the paintings and smirked. She simply swiped her hand they all stopped talking and went into a deep slumber. Albus smiled at the woman deciding it best that he not get on her bad side.

"Hello there, would you like a Lemon Drop Miss?"

Dumbledore asked hoping he would get an inclination as to who this woman was. She gazed at him in curious way before saying

"I believe I shouldn't, mortal candy always gives me gas. My name is Hecate, Albus and I am happy to say your prayers have been answered."

Dumbledore looked at her almost dumbfounded.

"And what prayers are you talking about, Miss Hecate?"

The women smiled at him as if he was her pet.

"The ones where you wished for more help looking after young Harry Potter with Voldemort on the rise and all that."

Albus sat down slowly hoping she would follow, which to his relief she did.

"Are you here to offer your services as our new Defense Against the Dark Arts here at Hogwarts? Because I am afraid Miss Hecate that I do not just allow anyone into that position."

The woman just laughed as if she found the idea funny to be teaching something as trivial as Defense Against the Dark Arts.

"No nothing of the sort, I came here to tell you that the other gods have taken interest in this war, and they saw fit to make sure that you wizards win. For if Voldemort were to win it would be, detrimental to every magical being in the world."

Dumbledore gazed at the woman with curiousness and trepidation, she had said gods.

"And Miss Hecate what do you mean about 'other gods'? You speak as if you are not a witch."

Hecate smiled as if she was a professor and her student just asked the question she had been waiting to hear.

"Albus have you ever been curious as to how you wizards and witches received your magical ability?"

Dumbledore nodded his head.

"If I recall correctly the first wizards were born in Ancient Greece, and feared for the weird powers were cast from Greece to the land beyond the known world, into modern day England no?"

Hecate smiled again like he was her star pupil.

"Yes, that is very true Merlin and the others did not deserve that fate, but Zeus did not see it fit for my blessing into the world to mingle with mortals much. After much groveling however, he conceded to allow the original wizards to be kept alive but forbade me from helping those wizards with their gifts. They had to learn on their own."

Dumbledore gazed at the woman, before everything finally clicked into place in his mind, and realized that if this woman was who he thought then there was a chance for them after all.

"Miss Hecate, you talk as if you were there when the first wizards were banished."

Hecate gave him that smile again, and he knew for sure that this was the goddess Hecate, how he did not know but he knew she would be a powerful ally. Her smile vanished however as the thought of ally entered his head. He realized she had most likely read his thoughts and he quickly cleared his mind of everything, not wanting to make the deity angry at him.

"Relax Albus I will not hurt you, sadly I cannot interfere in mortal affairs to that extent, but Zeus has deemed fit to lend a set of hands to help your cause and protect Harry Potter. For this however you must open the position of Groundskeeper and allow our hero to accept the position. It should also be mentioned that they shall need lodging made available to them."

Dumbledore raised a curious eyebrow it was a strange request, but one he could live with. He would merely give Hagrid the position of Care of Magical Creatures, Professor Kettleburn had asked to retire last week.

"Okay Miss Hecate, we greatly support the gods assistance in this matter, but I mean this in the best way. What interest do you have in our conflict?"

Hecate gave him a small sad smile.

"Sadly, I am not allowed to say, however I will give you my word on behalf of Chaos herself that we have the same interests in protecting Harry Potter, and want to see Voldemort fall."

There was a resounding clap of thunder in the air, along with several strikes of lightning all around the Castle of Hogwarts, and Dumbledore's office seemed to become 20 degrees colder when Hecate mentioned the name Chaos. While Dumbledore did not know the consequences of breaking the promise Hecate just made, he assumed they were severe given the reaction of the world to the promise. Plus, if he remembered correctly Chaos in Greek myth was the creator of all, so Dumbledore imagined the creator did not like to have promises broken on her name.

Dumbledore stood, and offered his hand to Hecate to which she took. "I greatly appreciate the promise you have made Milady, it settled many of my fears."

Hecate smiled and shook his hand back.

"I suppose you know, that no one can know of my presence being here. The portraits won't remember a thing. You will be the only wizard to know the existence of our kind, and if you fall back on that trust, then your civilization will be wiped out."

Dumbledore nodded numbly understanding that this woman alone most likely had the power to make the entire wizard community fall with a small wave of her hand.

"I understand Miss Hecate, where should I find the person, taking position of Groundskeeper?"

Hecate looked him in the eyes and for a brief second Dumbledore saw the endless amounts of magical knowledge, and power behind them. Once again confirming his belief that this was a goddess.

"You will find them at the Leaky Cauldron one week from now."

With that the goddess stepped back, and Dumbledore expecting the same flash of light looked away. When he turned back she was gone, and the portraits slowly started to wake up from their sudden slumber. Moving from his desk to the door Dumbledore realized that he was now incredibly late to the staff meeting, and sighed, how he would explain his tardiness he did not know.

Percy POV: __

Some people might think that being the hero was something to strive to be, everybody wanted to be the hero. Except the hero's themselves that is. When all the new campers at Camp Half-Blood look at me, they see the great Percy Jackson. The slayer of Kronos, One of the Seven, Survivor of Tartarus and so many more undeserving titles. What they don't hear is I never could have defeated Kronos without my Wise Girl's help. I could have never made it through Tartarus without her. And the Seven was a group effort, without the sacrifice of Leo, Gaea would never have been put back to sleep. He is the real hero of the Seven. I was thankful that the Physician's Cure saved him, and at the same time he fulfilled a promise I made when I was sixteen

While all of this was going on in my head I didn't notice Annabeth coming up behind me, until I was suddenly surrounded in darkness, and then a light feminine voice whispered next to my ear.

"Guess who Seaweed Brain."

Chuckling to myself I said.

"Jason? Dude how many times do I have to tell you Annabeth is at camp we can't show our real feelings"

I could almost feel Annabeth's smirk at our weird bromance before saying.

"Is there something you want to tell me Percy?"

I grinned before grabbing her hands and flipping her over me, her momentum bringing me on top of her. I looked into her eyes seeing the vast grey pools of knowledge I had come to love so much.

"Yeah Wise Girl, just how much I love you."

I saw her smirk turn into a small, soft smile before she leaned up slowly. I met her half way giving her a small, loving kiss. When we broke apart she just stared at me before saying

"I love you to Seaweed Brain. Now come one Chiron wanted to see us at the Big House."

I groaned slightly at having to move but nonetheless chivalrously held my hand out to her, pulling her up, before dusting the sand off my pants. We started walking back towards the Big House my hand intertwined with hers.

After a nice relaxing 15-minute walk to the Big House, were we did nothing but enjoy each other's company. We walked in the door to see Chiron standing with a woman who screamed goddess. She wore a white robe and had a strong green aura around her. Groaning internally, I realized she was here because she wanted something, that's all the gods ever visit us for.

While Annabeth took a small bow as a sign of respect I just merely glanced at her, after everything I did for the gods. There was no way in Hades was I going to let them drag Annabeth and myself away from each other, and into another quest. If the goddess was offended by my lack of respect she clearly didn't show it, instead it looked like she was smirking like she already knew what I would do.

Annabeth elbowed me in the side for not bowing, but I looked at her incredulously like. "You already know they are going to ask us to go on a quest Wise Girl"

She gave me a hard look in return that said. "Bow to the goddess Percy or you will have a lot more problems than her." Her gaze softened slightly. "I don't want you to go missing again for 8 months."

Sighing I leaned down and gave the goddess a small bow, before standing up straight and seeing Annabeth smirk at me triumphantly. Chiron finding this all slightly amusing cleared his throat, and I gave him my full attention. In my opinion he deserved so much more respect than half the gods on Mount Olympus.

"Percy, Annabeth, this is Lady Hecate. She has a favor to ask the both of you, I will let her explain the details more. I may be a bit bias when presenting the facts."

With that Chiron started walking out of the room, not before stopping at us both and whispering so only we could hear.

"You two have done more for the gods then anyone in this century, and arguably all of history. I want you two to know that you don't have to do this."

With that Chiron walked out of the Big House, and all of our attention was on Hecate. She looked up at us, and then down to our entwined hands smiling softly before speaking up.

"Thank you both for coming, and I would like to thank you especially Perseus. For helping not only myself but the other minor gods be respected, and our children to have homes here at camp."

I nodded remembering the sacrifices made in the Battle of Manhattan, and how many minor gods, and their children turned away from Olympus because they were not given the respect they deserved. "You are welcome milady"

She smiled before frowning slightly. "Which is why it hurts me to ask that you to go on a quest for Olympus and the gods."

I zoned out after hearing the word quest I was furious. I couldn't, no I wouldn't go on another quest for the gods. Annabeth and I had done our fair share, and then some. No way in Hades, not gonna happen. I noticed Annabeth looking at me with concern in her eyes and slight fear. I grimaced and started to beat down the anger that had started to rise inside myself.

After closing my eyes and counting to ten I looked around and noticed a sea green aura slowly dissipating. I looked back at Hecate and saw her looking at me curiously before she then turned her face into a mask. I nearly growled at the goddess, shocking myself slightly.

"No, I will not take part in any quest, don't you pompous assholes think we have been through enough? I just want to spend a year with my Wise Girl, before moving to New Rome, where we can have a peaceful life together."

I didn't even feel; Annabeth's hand nearly breaks mine. Or hear the deafening crack of thunder followed by a low rumble in the sky. I was done helping the gods for a while I just wanted to relax with Annabeth. Speaking of her I glanced to my right and saw her looking down right murderous at me, before I remembered what she said earlier. I looked a little sheepish before I squeezed her hand. Her glare softened a little and we turned back to face the goddess.

Hecate once again looked at us, she looked a little crestfallen before continuing.

"I am sorry Perseus, but it is not as bad as it sounds, please hear the rest of what I ask. Then make your decision."

I grumbled a little bit before nodding my head letting her know I wouldn't interrupt her. I felt Annabeth lean into my side, grounding me to the spot. Hecate started again.

"As you know how the mist surrounds our world, and how it hides the supernatural from mortals yes?"

We nodded our heads.

"Good, now the reason the gods are asking the two of you for help is that there is an enemy who seeks to destroy and control mortals, and the means in which he attends to do so is through the supernatural. Which would be bad, and while might not immediately affect us, over time it would have severe repercussions on the godly world. Mount Olympus, Camp Half-Blood, everything supernatural would be seen by mortals. In turn making all mortals clear sighted."

I grimaced It would be bad, and demigods would no longer be safe. Mortals would go into a panic at seeing the monsters, and no doubt get themselves killed while trying to fight them. It would not be good, Annabeth also looked troubled clearly seeing the repercussions.

Hecate continued. "There is a boy destined to fight this enemy and while it is unclear who will win the prophecy surrounding them says that they can only die by each other's hand. So, all we are asking is that you two go to the school where the boy is at and help protect him. The stakes are extremely high which is why the gods have decided to intervene in such a way."

I nodded numbly still processing all the damage that would take place should the mist fall. Annabeth and I would never get our oh so earned happily ever-after if the mist fell. I sighed before looking at Annabeth, I would not do this quest alone. When I said the two of us were not getting separated ever again, I meant it.

She looked at me a soft unspoken agreement formed between us, then looking back at the goddess she said.

"We will do it Lady Hecate."

Hecate smiled, good. Now there is some information I left out, so you might want to take a seat. It will take a while. A love seat magically appeared behind us, Annabeth and I sat down, after getting comfortable. I spoke

"Okay what did you leave out?"

Hecate sat down as well.

"To start I suppose that you both will be traveling to England."

I groaned, and Annabeth looked slightly excited, she whispered to me. "I have always wanted to see some of the architecture in England."

I smiled slightly and whispered back. "Once a daughter of Athena always, a daughter of Athena."

She smacked my arm lightly, but I just kissed her cheek before turning back to Hecate.

Hecate continued, "There is also the matter of both of you are going to be blending in with wizards, and witches."

I gasped and stuttered a bit.

"Do you mean like the people with pointy hats, that fire spells and stuff from wands?"

I always wanted to be a wizard, and while some might find it shocking that I took the information in stride. Just think we our children of the gods who are still around, wizards aren't exactly the most unbelievable thing to happen to me.

Hecate nodded her head, smiling at my enthusiasm. Annabeth giggled a little bit at my excitement and I stuck my tongue out at her and she stuck her tongue out at me. I crossed my eyes and she doubled over laughing and I grinned at my triumph. After a minute when Annabeth stopped laughing Hecate continued.

"Yes, I blessed about 40-50 or so mortals during the times of Ancient Greece, with the power to harness the magical energy around them and focus it through a wand something that I gave each of them. Zeus however did not like my interference, and feared mortals having that much power. After much begging, and some favors they were allowed to live. However, I was not allowed to teach them, they had to figure out the gift on their own."

Annabeth and I nodded along

"I was satisfied with them being alive, and I watched as they thrived with their gift and began to help the world, but soon people began to fear them for their power, so they went into hiding from the mortals and worked on their gifts in peace."

We nodded, understanding their struggle with mortals fearing them because they were different.

"Sadly, they forgot were they came from, they forgot their roots. Things became violent, and after some time they believed themselves above everything else magical creatures included. When that wasn't enough, they began to hate those who had not been born from purity."

It felt as if Hecate already knew my question, because just as I was about to open my mouth. She answered it.

"Blood purity refers to how people received their magic. The gift I bestowed was very finicky in who it chose to let wield it. For that reason, some people born did not have the gift. Which lead to the problem today. Those who had parents where both were magical were considered pure, while those who only had one magical parent were called half-bloods, and those without a magical parent were called mudbloods. However, those without a magical parent must have had a magical relative somewhere along their family tree."

I nodded in understand, hating the fact. Anyone who saw themselves as different just because they got their ability in different ways infuriated me. Sensing my anger Annabeth started to rub my arm before leaning into my side. I calmed down a little and looked over to see an angry face on her as well. I grab her hand, and then intertwined our fingers. She looked at me and I kissed her lips.

"We can try and do something about that while we are there Wise Girl."

She nodded her head before laying her head on my shoulder our attention back on Hecate.

"Thankfully there are some who do not think that way. For instance, the Headmaster of the school you will be going to, Albus Dumbledore doesn't believe that way. Neither does the boy you are to protect Harry Potter.

I nodded my head before stopping.

"What do you mean school?"

Hecate smiled slightly. "The Headmaster, Albus has opened a job for you, as groundskeeper. There you will be able to keep an eye on Harry and have freedom, you will also be able to stay with Annabeth in the housing the Headmaster provides."

I could feel my face heat up. Annabeth and I have slept together almost every night since we got back from Tartarus, it was the only thing that kept the nightmares of the pit at bay. Hecate spoke up again.

"And yes, your parents have agreed to this, there was much yelling but they care. They also understand, plus while in England you both will be adults, the age of adulthood there is 17"

Hecate finished with a smirk and a knowing wink. If my face wasn't red already it was now. I looked over at Annabeth, and saw her just as red.

Once our faces cooled down Annabeth asked a question

"Lady Hecate should we let the wizards know that we are demigods?"

Hecate shook her head.

"No, not unless it is necessary, the only person who knows will be Dumbledore. If the entirety of the magical community found out it would be devastating, and I feel they would fear our power and start a war. Similar to what they have done with the other magical creatures in their world."

Annabeth nodded her head.

"So how do you expect us to blend in? I doubt that monsters will stop tracking us, plus wouldn't the wizards find it odd that we do not have wands? Or the fact that we have no clue about magic, even though we are adults? Actually, can we even use that type of magic?"

Hecate nodded her head.

"Yes, well there are wards around the school similar to those of this camp, monsters will not be able to detect your scents inside. As for magic Zeus has allowed me to bless the two of you with the ability to control the magic like those of the wizards there now. However, you both will be much stronger in spell casting then most other wizards, because of your godly blood. As for the knowledge I will also bless you both with the knowledge on how to be proficient with Defense Against the Dark Arts, as my thanks for clearing my name after the Second Titanomachy. Finally, for the wands, and other supplies you both will need to visit Diagon Alley it is where the wizards go to shop."

Satisfied Annabeth nodded, I already had a headache forming with all this knowledge being shoved into my brain. I sure hoped Annabeth remembered the stuff about Diagon Alley. Hecate stood up and we followed.

"Now I will bless you all tomorrow morning, from there you will have two days to get your affairs in order. After that you will board a plane to England, yes Perseus a plane. From there you will shop and get your school supplies and then stay at the wizard pub until the Headmaster arrives."

I stared at the goddess incredulously. "What do you mean a plane, don't you know Zeus will blast me out of the sky?"

Hecate grimaced as a loud rumble of thunder could be heard from inside. "While it took much convincing from myself, Poseidon, Athena, as well as half the council. Zeus as promised to not kill you for coming into his domain this one time."

I grumbled a little bit, and it seemed Zeus agreed with me because the sky rumbled in defeat as well. Just as Hecate was about to flash out, I had one more question.

"Hecate what was the name of the school, I don't believe you ever said it."

She grimaced as if she didn't give the name on purpose and we had caught her trying to avoid it. She sighed before answering

"The name of the school is Hogwarts."

With that she flashed out, and I was left laughing like a fool, who names a school after a pig skin disease. Annabeth was chuckling as well before dragging me towards the door.

"Come on Seaweed Brain we have a to tell Chiron our decision, as well as your mom."

I groaned. "Annabeth can it wait until tomorrow? I am exhausted, and I know you are too, let's go to bed please."

I gave her my best baby seal face, and after she looked at the clock she smiled back at me.

"Sure, Percy we will tell them in the morning."

With that we made the slow walk back to my cabin before I opened the door for her, and followed her in, closing the door behind me. After we got changed into pj's I got underneath the covers behind Annabeth and wrapped my arms around her waist pulling her close to me. I kissed her neck before whispering in her ear.

"It's hard to believe we will be wizards tomorrow huh Wise Girl."

I felt her nod her head before yawning. "It sure will Seaweed Brain, goodnight. I love you"

She snuggled up a little closer to me and I tightened my arms slightly around her. "Goodnight Wise Girl. I love you too."

With that I drifted off into a nice dreamless sleep.
