Hello y'all. This story came to me in a flash of inspiration last night, and I couldn't stop writing. I noticed that there was not many Percy/Harry stories, so I decided to contribute to the small pond of them.

I hope y'all enjoy this.

DISCLAIMER: I do not own HP or PJ.

Hecate was an ancient goddess. Her magical prowess was nearly limitless, exceeding that of even Zeus. She had many followers and devoted worshipers. What most tended to forget about Hecate, however was her ability to read the future.

Hecate knew she would mother many children, but none of them would be her true heir. After many glimpses into the future, spanning over centuries, she finally struck gold. She foresaw a son that would master, and wield, magic so powerfully that he would eventually even be able to best her in a fight.

The only downside to her plan was the aura of death that clung around her beautiful child. The aura was distinctive to all children of Hades. Hecate would have to plan carefully to somehow convince Persephone to allow Hades to father her an heir.

After much deliberation, Hecate finally came to conclusion that they would all agree on. Smirking to herself, Hecate wrapped herself in her robes and transported to the underworld.

Hecate arrived at the gates to Hades castle. Quickly bypassing the skeletal guards that lurked around the perimeter, Hecate pushed through the doors of the majestic black castle.

Upon entering Hades domain, Hecate felt an unexpected chill crawl up her spine. Shaking off the strange feeling, Hecate fluidly made her way to Hades throne room.

Throwing open the doors, Hecate is immediately greeted by the chilling blast of Hades powers.

"And what makes you think you can so carelessly enter my domain, Hecate?"

Hades black eyes bore deep into Hecate's own acidic green.

"I came to ask a favor of yourself and your wife."

Persephone's dark eyebrow cocks in surprise. Leaning forward and propping her head in her hand, Persephone asks the most obvious question. "What favor?"

Hecate gives Persephone her friendliest smile.

"I would like Hades to help me father my heir. The Fates allowed me a vision of what he would look like and how powerful he would be. Hades and I would not need to have sex, we would simply need to mix our essences together, and then you Persephone, would carry the child. Technically the child will inherit mine and Hades powers, but he shall be considered your child as well."

Persephone's eyes widen in shock and she instinctively leans back in the throne like chair Hades had constructed for her. Glancing at her husband, she and Hades share a look.

"How powerful will he be?" Hade's black eyes pierce Hecate.

"He will succeed my own power, and if what I saw is to be true, he shall master your Hallows."

Hades' eyebrow cocks. "The Hallows are notorious for not taking a master."

Hecate's laugh is light and mysterious. "Exactly."

Hades leans back into his throne. Threading his fingers under his chin, he gains a thoughtful look on his face.

Minutes pass by before Hades finally comes to a conclusion.

"I will allow this. And if he is as powerful as you say he will be, I shall make him my heir as well."

Hecate's smile is radiant, as she looks at Persephone for approval.

Persephone slowly nods her head.

"Yes, I will bear this child. And he will be my heir as well. I will grant him my powers as well."

Hecate and Hades both eye Persephone in shock.

"You truly will, my beloved flower?" Hades asks stroking Persephone's arm.

"Yes, my love. We have both wanted an heir for many eons now and Hecate is giving us the perfect one on a silver platter." Persephone turns her amethyst eyes towards Hecate. "When shall we begin?"

A sly smirk forms on Hecate's ethereal face. "Now."

The procedure was grueling and the pregnancy reached almost sixteen months long, but finally a beautiful heir was born.

A little boy with skin pale as death emerged from Persephone's womb after a painful forty-eight hour labor. His chubby face was scrunched and his little hands were waving madly in the air.

Hades gently plucks the newborn babe from Hecate, carefully lifting him up and inspecting all angles of him.

"So this is the little heir?" Hades runs a hand over the babe's silky black hair. "What shall we name him?"

Persephone smiles before taking the baby back from Hades.

"Hadrian. His name will be Hadrian."

Hecate beams at Persephone before summoning the newly named Hadrian to herself.

"Such a simple name for such a powerful new god." Hecate coos at Hadrian as she traces a finger over his face.

"Yes, but I feel he would like nothing else." Persephone smiles as she watches Hecate play with their new heir.

"He will accomplish many feats. However, my most important question is who will train him as he grows up?"

At Hades' question Hecate's face grows despondent.

"The Fates have shown me that we must allow our heir to be raised by the mortal race of wizards. He is to take the place of a child that is fated to pass tonight."

"WHAT?! I will NOT allow my heir to be raised by mortals!" Hades normally calm composure is contorted into a visage of indignant anger.

Hecate shakes her head, her beautiful brown hair falling in front of her face.

"I am no more happy about this than you Hades, but the Fates say it is the only way our son will grow up without being consumed by the power he possess."

Hades calms down enough to pluck his new heir from Hecate's arms and make his way to sit down next to his wife.

"If we must allow him to be raised by mortals, I will make sure that I keep a close eye on my son growing up."

Persephone shakes her head vigorously. "I agree. I will not let our son go without anything he needs."

Hecate gives the two a gentle smile. "I would not have it any other way."

The three jump when Hadrian makes an unexpected noise from his place in Hades arms. The trio looks down at the infant in Hades' arms when they immediately feel their breath be taken away. Hadrian's eyes had finally opened, and they were the most mesmerizing thing any of them had ever seen.

The iris was Hecate's own acidic green with Persephone's amethyst color rimming the edges. Even Hades' eye color was incorporated in the black flecks that were sprinkled throughout his eyes.

"Do we really have to give him up tonight?" Persephone was giving Hecate her most powerful pair of puppy eyes, and coming from Persephone, that was saying something.

"Yes, but we will all go with him to drop him off." Hecate stares off into space. "Which we will need to do soon."

Hades nods before summoning an onyx stone to his hand. After engraving his insignia into it, he places it on a cord and ties it around Hadrian's neck.

"This will allow me to know if he is ever in danger. He might be a newly birthed god, but I do not trust mortals with my heir."

Hecate and Persephone both nod their heads in agreement.

"We need to take him to his temporary home now."

Hades and Persephone nod before transporting after Hecate.

Arriving at a small cottage, the three gods look around at their surroundings.

"This is where Hadrian is going to grow up?" Persephone asks Hecate.

Hecate sighs despondently. "No, I could only wish, but no. A Dark Lord is going to attack this cottage in an attempt to kill a baby named Harry Potter. Our young Hadrian will take over the place of this Harry and fulfill the prophecy that the Fates have foresaw."

Hades grumbles under his breath before nodding his head toward the dark clothed figure making its way towards the cottages front door.

"I think we have found your 'Dark Lord'." Hades' nose scrunches up. "He reeks of forbidden magic." Hades' eyes narrow on the dark figure before he growls low under his breath. "That fool has created Horcruxes!"

Hades' dark powers begin to seep out from him before Persephone gently places a hand on his arm.

"I know how much cheaters piss you off, but we need to get our heir into this Harry's room before he beats us to it."

Hecate and Hades nod before transporting.

The trio, plus baby, arrive in Harry's room just as the Dark Lord casts the killing curse at Harry. Watching sadly as the infant's soul leaves its body, Hecate pauses time before gently plucking the now corpse from the crib and placing their heir into it.

When Hadrian gives his parents a confused look, they are quick to reassure him that they are not leaving him for long.

"We will always be here when you need us, my son. Just remember that the necklace you wear is only visible to you and that whenever you need us, to think of us. We love you, and we will be with you during your stay with the mortals."

As each god takes a turn kissing and saying their temporary goodbyes to Hadrian, Hecate rewinds time to the exact moment Voldemort cast his avada kedavra.

Unpausing time and watching as the curse rebounds off of Hadrian and destroys Voldemort's mortal body causes Hades to smirk.

"Teaches that cheat not to mess with death."

Persephone only rolls her eyes before tugging on his sleeve.

"We need to leave before all the mortals arrive."

The trio nods before waving goodbye to their son and vanishing into air just as Sirius Black runs through the door.

11 Years Later

Hadrian sits in a compartment on the Hogwarts Express. He is rolling an onyx pendant through his fingers as he thinks about the past eleven years of his life.

He knew that he was a god, son to not only the patron goddess of Magic, but to one of the Big Three and his wife. He understood why they had left him on Earth with his 'relatives' the Dursleys.

His parents had instantly stepped in when the Dursleys had tried to make Hadrian their slave. They had made it to where Hadrian had his own bedroom and was made to do nothing around the house; though Hadrian still worked in 'aunt' Petunia's garden. He secretly suspected that his love from it came from his mother Persephone.

Sighing as he mentally reviewed everything his mom had told him about Hogwarts, he was interrupted from his musings when his compartment door slid open.

A pale slender boy with silver eyes and pale blonde hair entered his cabin flanked by two goons that easily put Dudley to shame.

"I heard Harry Potter was on the train today, you wouldn't have happened to see him, would you of?" The blonde's pompous attitude instantly grated on Hadrian's nerves.

"No, I cannot say I have seen him today. I am terribly sorry." Hadrian kept his voice polite and short, just as his father had taught him.

The blonde eyes Hadrian's clothes before holding out his hand.

"The name is Malfoy, Draco Malfoy." His voice came out superior, as if Hadrian should recognize who he was.

Hadrian weighed the pros and cons in his head before finally deciding to shake the blonde's hand.

"Hadrian."

Draco's eyebrow inches up on his forehead. "Just Hadrian?"

"Just Hadrian." Which was true, as gods did not technically have last names.

Draco nods his head. "Well, you will find that some Wizarding folk are better than others Hadrian."

Hadrian nods his head, "I will strive to remember that."

Draco gives a curt nod before turning on his heel and striding out of Hadrian's compartment, his two goons following.

Hadrian rolls his eyes before sending his parents a silent prayer to make it through his school years without killing anyone.

The sorting had been going on for a good thirty minutes before Hadrian's name was finally called.

"Harry Potter."

Hadrian quietly made his way to the front of the room, ignoring the gossip and Draco's disbelieving look.

As the sorting hat was placed on his head, Hadrian instantly felt the presence of another being inside his mind.

"Ah, this is very interesting. I've never had to sort a god before, let alone one posing as a dead student."

"Well, you are the sorting hat, so get to sorting already. We are holding up the line."

"Impatient are we? No need to be, they can wait. But very well. I see a lot of wisdom in you, Ravenclaw would be proud. I can also sense a deep seated loyalty, Hufflepuff would commend you for that. A lot of courage and bravery also lurks in here, Gryffindor would suit you well. But no. I think Slytherin would be the best house to place you in. I can see a lot of your father's slyness in here. You would eat the other houses alive. So it better be... SLYTHERIN!"

Hadrian places the hat back on the stool, before making his way towards Slytherin table. No applause is made and basically everyone is gawking at him, including the esteemed headmaster.

Finally, after finding a place to sit, Slytherin table begins to madly cheer and gloat towards Gryffindor.

Hadrian doesn't notice the put-out expression a certain redhead and bookworm share.

2nd year

It has been a year since Hadrian start Hogwarts and already this Voldemort character is wearing his patience thin.

Not only did Hadrian have to deal with an incompetent DADA professor, he also had to put up with his Head of Houses' constant belittlement.

After a long unfruitful year, Hadrian 'fought' Voldemort for the Sorcerer's Stone. The 'tests' that had been set up were glaringly easy.

Hadrian had easily defeated the pathetic creature claiming to be a Dark Lord; though the image from the Mirror of Erised still lurked in his mind.

Shaking his head to rid himself of such thoughts, his attention turned back to the common room he was sitting it.

While his orchestration from the rest of the school was understandable, Hadrian truly did not understand why Slytherin house also participated in his isolation. One would think that since he could speak the language of their house's founder, it would gain him more potential allies in the snake house.

Hadrian sighs as he stands and leaves to find a place to talk to his parents, the soft mumbles of gossip about a captured weasel following him.

Stroking the onyx medallion in his hands, Hadrian calls upon his father.

A pillar of smoke arises from the darkness, and his father steps out from its billowing brilliance.

"My son, what is it that you call me for?" Hades voice is of a satiny quality.

Hadrian bows to his father before straitening and explaining his dilemma.

"A Weasley has been taken into the Chamber of Secrets, is it her time to pass, or do I need to save her?"

Hades eyes Hadrian in amusement before quirking his finger towards his heir. Hadrian immediately follows as his father sits on a conjured plush black couch.

"My son, you are twelve now. Still an infant among us gods, but your powers are already surpassing some of the more minor ones. Death magic has already begun leaking throughout your system, so you tell me if young Ginerva's rope is close to being cut."

Hadrian nods his head and follows his father's instructions on how to see the thread of life surrounding every living being.

"Her thread is not to be cut yet."

Hades smiles softly at his son. "Then go save this mortal, my son."

Hadrian nods his head before making his way towards the Chamber, the sword all three of his parents crafted for him resting lightly on his back.

7th year

Hadrian had been hunting down Voldemort's Horcruxes for a couple months now and had finally managed to collect all of them besides the diadem and his pet snake.

Hadrian lightly petted his father's ring and cloak, smiling when they hummed in response to him. All Hadrian had to gather was the wand from Voldemort and he would have collected all of his father's Hallows.

Throughout the past couple of years Hadrian was faced with many obstacles. Not that the obstacles were necessarily difficult, but they proved themselves in the way that they helped shape Hadrian.

Most gods were cool or indifferent, but being on Earth and learning all that it had to offer in the terms of humanity had caused Hadrian to grow up with a passion for all living things. Something of which his parents silently approved of; they did not want an egotistical heir.

Sensing Voldemort's magic approaching Hogwarts, an evil smirk graces Hadrian face as he gathers his magic and disappears in a swirling black mist.

The final battle had been won. Hadrian had destroyed the rest of Voldemort's Horcruxes, including the one that tried to cling onto him. Hadrian chuckled manically under his breath as he thought of what his father would do to the cheater.

Looking out over the battlefield, he was pleased to note that many of the fallen were Death Eaters.

Hadrian felt his mother's hand grasp onto his shoulder.

"My son, you have done well. Your father and other mother agree with me that it is time to start your more formal training."

Hadrian looks into the matching eyes of his mother, Hecate.

"We're will you be sending me?"

Hecate gives Hadrian a sly grin.

"First you will spend a thousand years working with Salazar Slytherin, then Hufflepuff, Ravenclaw and Gryffindor. Once your training with the four founders is complete, you shall spend two thousand years working under the guidance of my most powerful half-blooded son, Merlin."

Hadrian nods his head thoughtfully, "Will I be traveling back in time, or will I be training with them in father's realm?"

Hecate gives her son a proud smile. "You will be training with them in Hades' realm; however you shall be placed in a part of it where time does not pass."

Hadrian again nods his head before eyeing his mother carefully. "There is more that you are not telling me."

Hecate smirks at her son. "After completing training with them, you will get personal one-on-one training with Persephone, Hades and I. Unlike with your first part of training, we will keep you until we are absolutely sure that you have mastered your powers."

Hadrian groans. "When do we start?"

Hecate pats her heir on the head. "Now."

Many eons later

Hadrian stood before his parents with his head held high. His training had lasted for eons, but eventually he had met and surpassed the goals and expectations his parents had for him.

Hadrian could now not only best each of his parents individually in battle, his power was so great he could beat them all three at once.

Hecate, Persephone and Hades could not be more proud of choosing Hadrian as an heir. They had never felt power as righteous as his, and were infinitely glad that he was their son and heir.

The three gaze upon their son, whose appearance was set on that of a seventeen year old. His skin was still as pale as death and his height only reached 5'4 when he was not in his god form. His inky black hair fell in waves around his body and his enchanting eyes had only grown even more beautiful.

"Today is your 20,000 birthday, my son." Hades began. "And I and your mothers understand how important finding your mate is to you. So as a birthday present and a graduation present, we will tell you where to find your mate."

Hadrian felt his magic jump in excitement at the declaration. He had waited so long for the opportunity to meet his mate. After waiting so long to meet his mate, Hadrian didn't care if they were a troll.

"Your mate is the half-blood son of Poseidon. He is currently making his way to Camp Half-Blood. If you wish to meet him, we will send you there under the guise as one of our own half-blooded children."

Hadrian's eyebrows scrunch together in confusion. "Isn't Chiron and Dionysus stationed there? Wouldn't they be able to recognize my powers as a gods and not a half-bloods?"

Hecate nods her head, "Yes, but we have already thought about this. I will place a charm on your necklace that will act as a mask to cover up your powers, but because you are so powerful, Hades will have to claim you as his."

Hadrian rolls his eyes skywards. "Good thing I have already met Uncle Zeus, or I would fear that he would attempt to somehow kill me."

Persephone lets out a small giggle. "Yes and I would say he found the lightning bolt on your forehead quit ironic."

Hadrian pouts at his mother before giving his father big puppy eyes.

"Yes I would say that my idiotic brother found that too amusing." Giving Hadrian a sympathetic look, Hades gently tugs on a lock of Persephone's hair. "Quiet, my love, we must inform our son of the happenings."

Persephone instantly sobers. Sharing a quick glace with Hecate, Persephone heaves a sigh.

"Your mate is being framed as the Lightning Thief to Zeus' master bolt. However, because we had Hecate here, we were able to realize that the traitor was actually the son of Hermes. Zeus and Hades, on Hecate's suggestion, have decided to still pretend that they believe your mate is the thief. It will give your mate a quest to go on, and as long as you volunteer to go along with him, you will be able to bond with your mate."

Hadrian nods his head. "What is my mate's name?"

Hecate smiles brightly at her son. "Perseus Jackson, though I hear he prefers to go by Percy."

Hadrian gives his parents a radiant smile, his white teeth catching on the non-existent light in the throne room.

"You better claim me fast father, because I am not sleeping in a cabin full of Hermes children."

Hades chuckles softly before making a shooing motion with his hand.

"Go on and get to the camp, you little brat."

Hadrian flashes his parents one last smile before disappearing in a swirl of shadows.
