The first chapter was written by DZ2. I adopted this story from them and everything after the first chapter is all me. This may seem like an odd choice of parents for Harry, but I hope you'll stick with me. DZ2 did a great job introducing the characters and I thought it would be interesting to see where this goes.

This story will first go through the Goblet of Fire and then the Lightning Thief. That's my plan for right now. I will outline more when I get to end of the LT. Pairings are undecided.

Twice-Blessed Child Harry Potter/Percy Jackson Crossover

Rules

Harry is the Son of a canon God pairing, Greek or Roman. E.g. Zeus and Hera. Hades and Persephone. Mars and Venus. How Harry got to the Potters is up to you.

Harry's friends must all turn their backs on him. Whatever reason you wish to use is fine, just make it interesting. This rule doesn't apply if, and only if said friends are Demigods as well.

When Harry dreams of his godly parents he only hears their voices, he doesn't know who they are until they claim him at CHB. Harry can get hints and can be 100% sure but his parent cannot confirm it and claim him until he reaches the Camp.

Harry befriends a canon Demigod from CHB that is NOT Percy or Annabeth.

Harry must have some form of -kinetic power. E.g. hydrokinesis, pyrokinesis, umbrakinesis… Google them if you don't know what I mean.

At least ONE person from the HP-verse must be a Demigod and show up at Camp after Harry arrives. Neither of them can know the other is a Demigod until then however.

For whatever reason you choose Harry MUST be taken on the Quest for the Lightning Bolt. Maybe there is an added line in the Prophecy (Book) or his parents order him to go with Percy.

Forbidden

Demi-Titan Harry. If the Titan in question DIDN'T support Kronos in the war, then they're allowed.

Harry forgiving his old friends. They turned their backs on him, he can't forgive that now he knows what real friendship is.

Harry joining Voldemort. Even if you make Harry Dark he still wouldn't join Voldemort.

Midnight Hour

Harry tossed and turned in his sleep, his eyelids flickering with images of dreams and nightmares that whispered in his ear;

Once again, as he had done for a few weeks now, he saw the image of the Muggle caretaker from Riddle's home being put to death at Voldemort's command followed by the image of that accursed marking burning brightly in the night sky.

He saw the Death Eaters, dressed in their dark regalia, each one of them marching through the campgrounds of the Quidditch World Cup as they laid waste to everyone that stood in their way. He saw the Dark Mark being fired into the air by the mysterious man in the shadows and, last, but no means least, the latest and worst of Harry's nightmares.

He saw the looks on the faces of each and every single student and staff member in the Great Hall as he walked to the front of the room, his eyes cast down while his heart felt heavy. He could still feel Dumbledore's hands shaking him, demanding the answers about his name being put into the Goblet of Fire while others called him a liar, a thief, a glory-hound and a cheat.

Then, almost like old times had come back to haunt him, Harry saw himself walking to the Goblet of Fire before, with a flash of green light that he now knew to be the Avada Kedavra Curse, Harry was torn from his sleep, his face caked with sweat while his body, his lungs and his heart felt hot, clammy and out of breath.

Throwing his bedcovers off himself, Harry ran for the entrance of the Tower, his desire to be outside only enhanced by the sickness that threatened to well up inside him as he considered his nightmares.

This year, this school term: it was like the whole time was out to do little more than destroy him.

'Then again,' thought Harry, barely stumbling towards a direction that his senses couldn't make out: his consciousness was only seeing the darkness and, through the darkness, Harry could only see the outside.

The outside where he needed to be.

'My being destroyed by forces unknown is nothing new,' thought Harry, before he let out a desperate gasp as he found air rushing into his lungs, the darkness that clouded his vision now being cleared with each gasp of air. As his vision cleared, Harry saw that he was standing atop the Astronomy Tower's viewing platform, the endless stretch of Hogwarts and her grounds spanning every inch of his vision, but, as he reached the tower, Harry doubled over and vomited hard, the sickness he'd felt earlier now being let out.

His body trembled, his legs felt wobbly and still, his heart hurt, but now, the hurt was mirrored by the desire from before: the desire to be out in the open, almost double-so now that he was standing here in full view of the night sky.

Using the wall to steady himself, Harry took a deep breath and, looking to the sky, he roared, "WHY? WHY ME? WHY AM I FATE'S WHIPPING BOY? WHAT GOD WOULD FIND THIS AMUSING? JUST…Just please…"

Apparently exhausted by his cries, Harry fell to his knees, his hand clasped tight to the railing as he pleaded, "Please just tell me: why am I the one you all go for? What force of magic would let this happen over and over again?"

"Do you really want to know?"

Snapping his head up, Harry turned his head to see a woman standing in the shadows of the Tower: her skin was as pale as moonlight that made her look strikingly beautiful: her eyes were a yellowish shade of silver that seemed to remind Harry of the glare of the full moon, her eyes staring out at him from underneath a head of smooth, silken auburn hair.

She was dressed in a long silvery gown that seemed to trail around her safe for a hood that she wore half-way up her head, revealing her face and hair to Harry. As the woman stepped out of the shadows, Harry was surprised to note that she was barefoot and yet didn't seem affected by the hot or the cold no matter what sort of breeze blew through the tower.

"Who…who are you?" asked Harry, taking a step back as he seemed to sense something dangerous about this woman.

"Do not be afraid of me, little moonbeam," replied the woman, her voice rather light-hearted and edged by a musical lilt that seemed to calm Harry as he listened to it, "I could never harm you: as for who I am, you may call me Artemis, for that is my name."

Here, the woman, Artemis, paused before she smiled gently as she added, "Alternatively, my little starshine, you may also call me Mum."

Harry's eyes widened before he let out a gasp as a bright flare of golden light filled the tower, the glare almost too bright for his eyes, but when it faded, the glare revealed a strong-looking man with bronze, sun-kissed skin, sandy blonde hair, eyes that were like the color of the sun and dressed in a suit of brown, leather-style battle clothes.

"Sister," exclaimed the man, his voice making Harry feel warm and tingly inside as he asked, "What brings you to the mortal plane? Surely you do not wish to break your vow after all these years?"

"Now Brother," argued Artemis, "You know that we maiden goddesses do not need the act of consummation to sire children, though I confess that I have not done such a thing. Instead, I am here to claim my son, born of the blessings given to one who sought my help: what brings you here?"

"I too seek my child," answered the man, his eyes looking to Harry as he added, "Good evening, Harry: it is nice to see you again after all these years. I am Apollo, but you may call me Father."

Harry now had to look back and forth between Apollo and Artemis, both of whom actually looked stunned to see his disbelief as well as their presence within the tower. As he tried to make heads or tails of what was going on, Harry then noticed Apollo shining with a golden aura before Artemis also shone with a silvery aura, both of those auras moving towards Harry where, as they met over his head, they formed an image of the sun and the moon.

As Apollo and Artemis both stared, they both looked to one another before they both asked, "What? You? How?"

"Would someone please tell me what in Hades is going on here?" asked Harry, a part of him wondering where such an expression had come from while another part of him longed to learn more.

"I will, Son," answered Apollo, his eyes looking to Artemis as he added, "Being the God of Truth means I cannot lie."

"Neither can I, Ray Brain!" scowled Artemis, her voice edged by disbelief as she told Apollo, "We're twins, you dolt: we share certain traits, remember?"

"Ah," Apollo agreed, looking from Artemis to Harry as he added, "Sometimes I hate it when she's right."

For reasons he couldn't understand, Harry just laughed before he asked, "Look, can someone, I don't care whom, but can someone please tell me what's happening? I guess I can't really argue against your claims that I'm your son since you are gods of truth, so what's the real truth? Why am I here? Why are you here?"

"Because," answered Apollo, "If there's one thing my sister and I can agree on, it's that we're both sick to death of the mortals thinking they can run your life when you're the one with the power to truly decide your fate."

"And being a soothsayer and Prophet, he knows what he's talking about," Artemis reasoned, giving her brother a look of agreement as she explained, "We can explain everything, little starshine, but if you're going to listen, then it should be in better surroundings. Care for a little midnight trip, Harry?"

Harry opened his mouth to answer, but as soon as he did, Apollo had lifted his hand and, with a snap of his fingers that sounded like a firecracker going off, he summoned what looked like a golden chariot that was pulled by four red horses, each of them holding a mane that seemed to be made of pure firelight, their eyes replaced by burning embers while their wings were pure light.

"Wow!" gasped Harry, "What are they?"

"Solamares," answered Apollo, "Fire Horses: climb aboard, little sunspot: we can explain everything better on the road."

Harry felt like he could actually agree with Apollo's remark: climbing onto the chariot, he watched as Apollo turned before he asked, "Coming Artie?"

"I think I'll ride the Star Trailer," answered Artemis, before she ran off the edge of the tower and, to Harry's surprise, she then rose up on a silver chariot that was pulled by four golden deer with silver horns that made the young wizard think of Prongs.

Cracking the reins on his Solamares' skins, Apollo let out a jovial laugh as he took off into the skies, the night welcoming them all into its domain as Harry, turning to the sun-kissed being next to him, asked warily, "Where are we going?"

"Somewhere you can prepare for this stupid Olympics wannabe safely and cleanly," answered Apollo, riding out towards the west of the land where, as Harry looked down, he saw only the seas of the Atlantic Ocean before new land came into sight. As the land grew closer, Harry looked up to Apollo with a sense of curiosity, coupled with a sense of wonder as he realized, for the first time that night, what was going on.

He, Harry Potter, had just ridden in the infamously-legendary chariot…of the Greek God of the Sun!

That meant that Apollo's sister and the one that had told Harry he could call her Mum was Artemis, Goddess of the Moon and the Hunt;

'The only question is,' thought Harry as the chariot landed with a screech like a car's brakes, 'How?'

"Smooth and easy," laughed Apollo, dismounting from the chariot before he helped Harry down and, turning to the point that they'd landed at, he told Harry, "Welcome to your new home, son."

Turning to the point that the Sun God was looking at, Harry saw a stone entrance with strange writing over the top; as he looked at the writing, Harry thought that his eyes were playing tricks on him as he saw the writing rearrange itself to form three words:

CAMP HALF-BLOOD

"Half-Blood?" asked Harry warily, "Half-Blood what?"

"You mean you haven't figured it out yet?" asked Artemis incredulously, landing on her own chariot next to Apollo and Harry before she added, "I blame you for this, you big Solar Flare show-off!"

"Don't blame me, Gibbous Head," scowled Apollo, Harry actually wincing as he realized exactly how these two were siblings: they certainly fought like them.

"Don't call me that!" hissed Artemis, before she turned to Harry as she added, "Half-Blood, Harry: as in half-God…a Demigod."

"Only," added Apollo as Harry's eyes widened with shock, "Except for you, Harry: you see, as my son and, apparently, as my sister's kid, you're also a Twice-Blessed Godling: someone with two divine parents…in this case, me and Artie."

"For once we agree on something else, Polly!" laughed Artemis, earning a smirk from Harry while Apollo turned dawn red with shame.

Still, even with his smirk, Harry still needed to know more and, for that, he had to stick around for a while longer, "So how exactly am I your son…erm…Mum and Dad?"

"Ah-ha," Apollo laughed, "Now we get somewhere; well, it starts over fourteen years ago…"

Let me know if you'd like me to continue.
