The Ascension

Chapter I.

Author's Note- This is an idea I had that would not go away. It's a Harry Potter/Percy Jackson and the Olympians crossover. It is somewhat similar to those Harry the Twice-Blessed Half-Blood stories out their from DZ2's challenge, but this is truly in response to Alpha Lycan 2001's challenge in Dec. 2014. You could call him a Transcendent demigod as part of Harry hails from the Greek Pantheon, while another part comes from the Norse Deities. Harry however, is utterly unique. Almost as if crafted by destiny or the Fates themselves, Harry will become a being of ultimate balance. Together with his destined love, Harry will become the check needed to balance the forces of good and evil, light and dark, and tyrants and the powerless. His ascension will shake the very foundations of the Earth. I have listed the requirement's of Alpha Lycan 2001's challenge below, and give him the credit for the idea...though I may not follow it exactly as this is fanfiction. For me, this is the ultimate Super!Harry or God!Harry fic. Also, just to let you know- this will not be overly focused on the Harry Potter Word. It will be more focused on the Percy Jackson Universe.

Challenge: A Harry Potter/Percy Jackson (or Heroes of Olympus)

Plot: Gods are divine beings with extraordinary powers, born from the union between two members of the same pantheon but sometimes, just sometimes, the members of two different pantheons come together and produce a child. These children are known as Transcendent Demigods and Harry Potter happens to be one such Transcendent Demigod.

Rules:

Light or Grey Harry.- Accepted- (Grey)

The reason for Harry being a Transcendent Demigod is that he is the child of deities from two different pantheons.- Accepted

One of Harry's god-parents must be a Greco-Roman deity. It doesn't matter whether they are Primordial, Titans or Gods, it just has to be someone from Greco-Roman mythology.- Accepted

Whoever Harry's god-parents are, they have to break the law and meet with Harry. Accepted

Harry must be betrayed by Ron and Hermione at some point or the other.-Accepted

Sirius and Remus cannot abandon him.- Of course not...Sirius is awesome!

Dumbledore may be anything from a blind idealist to a manipulative chessmaster and anything in between, but he is not and never will be dark and/or evil.-

Accepted...Dumbles is very manipulative...(for 'the Greater Good' of course.)

Harry as a Transcendent Demigod has no true limits on his powers that he does have and can therefore potentially become as strong or even stronger than the Primordial Gods, but the downside is that he ages at the same rate as a human and must work to develop his powers, they will not come to him naturally as they do to the gods although he may temporarily access a hidden reserve of power in times of great need and distress. Also he may never develop powers outside of those he inherits from his divine parents, unless it has to do with magic. Example: As the son of a Fire God and Earth Goddess he can never control water unless it's a spell of some sort.- Accepted

Powerful Harry- Accepted

Intelligent Harry- Accepted

Driven Harry- Accepted

Harry may not be bound by the Ancient Laws at any point whatsoever.- Certainly Not

Cover Image: I don't care what the image is. It can be a picture of Harry or a plain white sheet with the title written on it just have a cover image.

Guidelines:

Harry becomes immortal once his powers develop to a certain point but not before that, when is up to you.- Accepted

Harry may possess the generic abilities of a god, telepathy, superhuman strength, speed, reflexes, energy manipulation, teleportation etc: Accepted

Master/Champion of Death Harry: This particular guideline can mean that Harry is Master/Champion of Thanatos or the Death God of any pantheon but it can also means that he is the Master/Champion of the literal embodiment of Death itself a being above and beyond any pantheon:

James was a god in human form- Accepted

Lily was a god in human form:- Accepted

Other people of the HP universe are demigods: Accepted

Voldemort, Kronos and Gaea as allies of Harry.

Sirius and Remus abandoning Harry.

Dark or Evil Harry.

Prologue

Lily Potter nee Evans made her way through the crowds to a more remote area of the park. Even as a child in this life she had loved coming here. Kensington Gardens just exuded a sense of peace that was difficult to find in the magical world. She had thought long and hard about the decision she was making as well as the request she was about to ask. She truly loved the life she had, and she loved the man she was married to. She knew some would object to what she had done, but really! It had been over five thousand years since she last gave birth.

Regardless of her age, she was a rather forward thinker as well. She certainly considered being cut up and entombed in Tartarus for five millennia to be, at the very least, the equivalent of a divorce. By the Mother how she loathed that miserable excuse for a man. Well, she had done much better for herself this time, that was for certain.

Before she had chosen to live a mortal life, she had been filled with an unending sense of utter boredom and depression. For a deity of motherhood, five thousand years is a very long time to go without experiencing the wonders of being a parent. Her adult children were by and large, utter disappointments; especially her youngest son.

She hated to even think about how obsessed with power and control that one had gotten. Really, who was he to dictate so much to his siblings, nieces and nephews, and even his own children? She could rarely stand to be in contact with the majority of Olympus on most occasions. Were it not for the presence of her dearest and eldest child, she was certain the Olympian Order would have long since imploded on itself. Hestia, Poseidon, Hephaestus, Hermes, and Apollo were really the only ones she could tolerate.

She laughed quietly to herself as she imagined most of their reactions to her life and plans at the moment. They would have an absolute fit. She was sure the tantrum Zeus would throw would be of epic proportions.

She stopped her leisurely pace and came and sat down on a park bench commanding a beautiful view of the surrounding environment. It was not long before she noticed the presence of another being materialize beside her.

The woman appeared to be in her late teens. She was extraordinarily beautiful with dark brown hair, an enchanting heart-shaped face, and amber eyes that almost seemed to glow with fire. The young woman emitted an aura of welcoming and warmth that made it almost literally impossible to feel bad or unwelcome in her presence.

"Mother, it's wonderful to see you! Is this where you've been these past years?" Hestia asked.

"Yes, Dearest; it most assuredly is. I always did prefer Europe to the New World," the woman known as Lily Potter replied.

"Are you happy Mother? I know these past few centuries you have been increasingly displeased with the state of things on Olympus," Hestia asked.

"Yes, Darling. I can honestly say I have not been this happy in millennia, if not ever. Most of our kind would not consider it as such, but this mortal life I've lived these past twenty years has been a wondrous experience. Cousin Hecate did me a favor when I was incarnated in this life, and blessed me with magic, as I wished to make a difference in the state of things in the Wizarding world. I suppose I simply did not wish to lead a completely mundane life," Rhea, Queen of the Titans explained to her most cherished child.

Hestia gave her mother a beaming smile.

"Then I am happy for you Mother," Hestia told her.

"Now, I know you did not call on me just for an update Mother, so how can I be of help?" Hestia asked getting to the heart of the matter at hand.

Rhea released a sigh as she gathered her thoughts on how to broach such a sensitive subject to her eldest child.

"Two years ago, I got married," Rhea explained.

"I never thought it would happen to me again, but I fell in love with a wizard. I've been alone now for so long that it hadn't even entered my mind to change. His name is James...James Potter, and we went to school together in this life. We both were in the same house at Hogwarts. I'll admit that for the first few years I despised him for how arrogant I thought him to be. However, he went through some rather traumatic events, and became a man that I can say I am proud to be the wife of. I fell in love with him, and he's come to mean the world to me. I know that one day both our mortal lives will be at an end, but I'd rather have finally loved and lost, than to never have known real love at all; as the saying goes," Rhea explained.

Hestia was silent for a long moment as her mother explained her new life to her. She knew her mother had never truly known real romantic love before, and after all these millennia, she could hardly begrudge her mother the chance at happiness; no matter what her siblings would think of the matter.

She took her mother's hand in her own.

"If you are happy, then I am happy Mother. After all this time, if anyone deserves their shot at happiness, it is you. What's the problem then?" Hestia inquired.

"I cannot have a child. I love my husband with all my heart, and am unable to give him the one thing we both wish for the most," Rhea explained in a pained voice.

"What? How can that be, Mother? You are a divinity of motherhood. Even in a mortal body you should have no problems conceiving a child. You've never bore a demi-god before, but that is still no reason. I don't understand?" Hestia said.

"I do not think the problem resides in myself. I think my husband is sterile. Even then, that would normally be no real issue. My powers alone should have been enough to allow his seed to quicken. I believe he was cursed somehow. Even as powerful as I am, it appears as if it is not enough." Rhea explained.

Hestia thought about her mother's problem for a moment. She thought she knew what the problem was, as well as what her mother was asking of her. She looked up and she could see her mother knew she realized what she was implying.

"Could you help me?" Rhea asked in a pleading voice.

Hestia thought about what it was her mother was truly asking of her. Could she actually do it? If the curse was powerful enough that a divine egg from the Queen of the Titans was preventing Rhea's powers from allowing fertilization...the only way she could imagine overcoming the issue would be to use a more powerful egg. If she merged one of her own eggs and divine essence with her mother's...well, she was fairly confident nothing in the Universe would then be able to prevent her mother from conceiving.

However, that would make the child just as much her child as it would be her mother's. In all of Hestia's immortal life, she had never once produced a child in any way. She had longed for one over the years, but had been resolute in maintaining her maiden status and oath. This child however, would not be in violation of her oath. This could be the perfect way to fill the whole in her life she had been feeling for so very long.

As she thought about it her mother was studying her face intently.

"The child would be a very powerful demi-god if we did this. I know how you have yearned for a child of your own Darling. I would have no problems sharing. Any child would be truly blessed to have you for a mother as well." Rhea told her.

Hestia's eyes lit up with the knowledge that her mother would be willing give her a chance at motherhood as well. Even if it would only be from a distance, Hestia could already feel the excitement brimming at the prospect.

"Alright, Mother. I'll help. You deserve this chance after everything, and I'll get a chance for a dream of my own to come true," Hestia replied.

She giggled for a brief moment; amusement lightening her mood greatly.

"What?" Rhea asked with a smile on her cupid's bow lips.

"I was just thinking of my brothers. They are always so concerned about one or the other of them producing a demi-god more powerful than their own demi-god offspring. It's always a competition of sorts with them; to see who can have the most powerful child." Hestia said amusedly.

"Yes..." Rhea asked, wondering where her daughter was going with this; though she had a fairly good idea.

"Well...I am the Firstborn of Kronos and Rhea, and I have never had a child before; this will be my first. Imagine how powerful mine own Firstborn will be with you as the other parent of the first Twice-Blessed in centuries?" Hestia explained with an amused glimmer in her eyes.

Rhea thought about it, and laughed heartily.

"Zeus will have an absolute fit. However no laws will have been broken. He will be unable to do anything about it," Rhea said as they both dissolved in laughter at the thought of her youngest son's reaction.

"He would not dare make a move against you," Hestia said, eyes shining in mirth.

"Good, maybe it will nock his arrogance down a peg or two," Rhea said emphatically.

"Something needs to," Hestia grumbled.

"Alright, do you know what to do?" Rhea asked her daughter.

"I just place some of my divine essence into one of my eggs, and then I transfer it to one you will have prepared?" Hestia stated questioningly.

"Indeed, that is exactly how. Just make sure not to overdo it. It can be powerful, but too much power and it will burn itself out," Rhea explained.

Hestia nodded and took her mother's hand as she concentrated. She went deep into her own source of power, her divine essence, and extracted the absolute maximum she thought would take hold and fused it with one of her eggs. The two beautiful women began to give off a blindingly golden glow as Hestia transferred the egg from herself and merged it forcefully with the one she could tell Rhea had selected of her own. Rhea had luckily cast a notice-me-not charm when she arrived as even with the help of the mist any human very close would most likely have burned up from the power released as the two eggs merged into one extraordinarily powerful one.

When the glow died down, both women were winded from the exertion and energy spent forcing the combination. After she caught her breath, Rhea gave Hestia a beaming smile in gratitude. She knew with absolute certainty she would be able to finally have a child with her beloved husband as she had so desperately desired.

"Thank you Hestia. I can never thank you enough for doing this for me. Oh, I can't wait for you to meet him. I don't know how, but I somehow already know we're going to be having a boy!" Rhea told her daughter delightedly.

"Of course. You know I would do anything for you Mother. Besides, this is finally my own chance to experience a child as well. I can't wait to see what he looks like." Hestia said with a sigh of delight.

"Soon, My Darling. Now, I must be going. Would you like to visit the hospital with me when it's time for my check-up's about the baby?" Rhea asked.

"I'd love too, Mother. We can just say I'm an old friend. Ohhh, I can meet this husband of yours as well," Hestia said with a grin.

"Yes, yes, so you will. Now, I'd best go and see about making him," Rhea said devious smirk at how she planned to entice her husband to come home as soon as possible.

There was a flash of light and Rhea, known as the bright and beautiful young witch Lily Evans, was gone.

The months of Lily Potter nee Evans's pregnancy seemed to fly by, and before she knew it, she had gone in to labor. Oddly enough, it was exactly eleven months to the day since she had conceived; an extraordinarily long time for a human. Out in the waiting room stood a nervous James Potter with best friends Sirius Black and Remus Lupin. Inside, Lily was beyond relieved to note that her daughter had been as good as her word, and was in the room posing as Lily's 'birthing coach'.

Hestia had been with her to several of her appointments and was nearly as anxious as she was. You might think being a deity of motherhood made childbirth easier. However going by the screams and the way she was gritting her teeth while yelling out oaths of vengeance to her husband's 'man parts' on the man in the hall; it appeared like it was just as painful to her as anyone else. The poor unfortunate husband waiting outside was at one point even huddled into a corner rocking himself as his beautiful wife became especially creative in how she would have her revenge for this pain. He knew what she was capable of, and it scared the hell out of him and his bits.

It had by now been six agonizingly long hours since Lily had went into labor. Normally, for most women that would be nothing unusual at all. Lily however was not most women. Both she and Hestia were beginning to worry as she had never had a labor that lasted anywhere near this long.

She let out another scream as she was wracked with a particularly painful contraction.

The healer informed them that the head was beginning to crown.

That's when things started to become strange.

An unearthly golden glow began to fill the delivery room.

When Lily and Hestia saw what was beginning to happen they began to panic before their sense returned.

Grabbing her daughter's hand tightly, she told her to concentrate. They had to stop it.

As the (former) wife and Firstborn of the Titan of Time respectively, they both had very minor time manipulation powers; Hestia more so than Rhea.

Realizing what her mother meant, Hestia joined her power with her mother's as the two deities concentrated with all their might on stopping time from moving on around them.

They watched on as time visibly came to a slow halt.

They both let out a gasp at the power it took for them to accomplish such a feat.

"My girl, I need you to deliver our boy for me. Something's wrong; the little one is emitting a divine aura. How? I don't know, but the mortals would have burned up," Lily said as another contraction swept through her.

Hestia stared at her mother wide-eyed, not knowing what to do. She actually had helped to deliver children before, especially her sisters, but she was still thoroughly amazed that this baby was releasing a divine light. It shouldn't be possible. Even though he was a Twice-Blessed and likely one of the most powerful demigods the world would have ever known, he should have still been mortal. Her mother's grip on her hand reminded her there would be time enough to figure that out later. First, they had to bring him into the world.

Taking the healer's place, Hestia encouraged her mother to push.

Lily pulled from deep within herself, and drew upon all of her strength as she did as she was bid and pushed with renewed determination. Her perseverance was rewarded when not even five minutes later her first child in millennia took his first breath of air and let out a loud wail.

Hestia snipped the cord and waved her hand over the newborn; instantly cleaning him up. She wrapped him in swaddling clothes as she handed him to her mother.

Lily and Hestia both gazed down at the little boy in awe as they got their first good look at their mutual son. He was utterly beautiful; truly the most breath-taking babe either of them had ever beheld. He had Lily's (Rhea's) eyes. They were a stunning emerald green. He also had the softest light golden-blonde hair, although this somewhat confused them both. He was looking at the both of them when his appearance abruptly changed; startlingly. His hair changed to a jet-black that stuck up in various places. His facial features shifted slightly, though it was barely noticeable. His eyes however, remained the same emerald green that could be found on both Lily and Rhea.

Both deities suddenly tensed as they sensed the presence of another. Out of the room's few shadows appeared Hecate, the goddess of Magic herself. Hestia and Lily both relaxed upon seeing their old friend.

"Oh, My Queen, he is beautiful!" Hecate exclaimed as she gave a bow the Rhea.

Being of the generation before the Olympians when the Titans held sway, Rhea would always be her queen.

"Thank you, my dear. I'm a bit confused to see you at the birth though. Do you have perhaps any idea what is going on with him? For one thing, he does not appear to be a demigod. Also he has two appearances. At first I thought it might be the wizarding metamorphmagus ability, but that is not this. Do you have any clues?" Lily asked the Lady of Magic.

"Yes, my lady. That is why I have come. Oh and you can release your hold on the area's time. We're in a Wizarding hospital and I am able to essentially do the same in my domain with much less effort," Hecate said.

Both women released a sigh of relief as the pull on their own power disappeared as Hecate took over the job.

"Now, we must be quick, but here is what I have figured out. Essentially, your son is a god. However, he won't be fully immortal until he gets older and reaches puberty around the age of thirteen. As to how this is possible; well, that would be because of your husband," Hecate explained.

"James? How...?" Lily asked.

"James Potter was born a wizard, however he is also an incarnated deity himself; though he does not remember it. He is the divine essence of Thor Odinson; Norse God of Thunder and son of Odin Allfather and Queen Frigga. I detected something different about him, and finally figured it out as I had seen it once before with his brother Loki in the same situation. Sometimes in order to teach his children various lessons or as punishment for one thing or another, Odin will have them incarnated in the body of a mortal to live out a mortal life. I checked, and the Thunder God has been 'indisposed' for about the same amount of time that you have my queen. Though unlike you he is totally unaware of it." Hecate told them

"That would explain why you had such a hard time conceiving, Mother. He's from a completely different pantheon. While it has happened before, it it extremely rare." Hestia said.

"Yes, though because he is the biological child of both you and Hestia, he will be more Greek than Norse. His powers will also be limited to only things he would inherit from his three parents; though they will likely be phenomenal considering his is the Firstborn of both Hestia and Thor. The power of fire and the storm is an awesome and potentially frightening combination. He will come into his fully divine inheritance when he is around thirteen or fourteen years old and his growth begins to slow. You will all have to be careful until then. Until that happens he could be classed as a Transcendent Demigod. As he is now, this is his mortal appearance. The other is his divine appearance with both his Greek and Norse divinity mixed. In situations of extreme danger, he can force himself to tap in to his divine side early; thusly making himself indestructible. Regardless, he's adorable either way," Hecate said; finishing her explanation to the little god's two stunned mothers.

"What's his name by the way?" Hecate asked them.

"Well, I was going to name him Harry, until the Fates visited me and told me what his name must be. So Lady Hecate, allow me to introduce you to Hyacinthus Jameson Potter," Lily said.

"I did not know the Fates visited you about him?" Hestia said questioningly.

"Yes, that was all they said though. They would say no more on the matter. We shall still call him Harry as a nickname though as Hyacinthus is a bit much," Lily explained.

"Actually, for a wizard, it's practically tame," Hecate said dryly.

"True," Hestia agreed.

"I must depart now, but before I go, allow me to give him a gift my queen," Hecate said.

"What do you have in mind Hecate?" Lily asked.

"I will bless him with the metamorphmagus ability so as to get used to both forms as well as practice shifting without harming a mortal," Hecate explained.

"Oh, that's perfect, isn't it mother?" Hestia directed to Lily.

"Thank you my dear. I am yet again in your debt." Lily said tiredly as the days events began to catch up with her mostly mortal body.

Hecate laid her hand on baby Harry's head as he glowed a silver color briefly, blessing him with that power as well as several others she knew he might need later. She bestowed a kiss upon his brow to the one she knew was destined to change so many things in the mortal and divine realms both. She knew more than she should, but she would keep quiet. She could not wait to see what that beautiful babe would achieve. She was especially looking forward to when he united with his mate. Hearts the universe over would be crushed with the two of them off the market.

"I've altered their memories already, so you're all set." Hecate said pointing towards the mortals they had all but forgotten about.

Good bye My Queen, My Lady, good by Little Prince," she said as she blended back with the shadows and returned to her realm.

"Well, that was certainly enlightening," Lily said dryly; smiling tiredly as she cuddled her new-born son closer to her breast.

While Hecate's words had answered many questions, and given her many more; for the moment though, she was content to just bask in the bliss of holding her child in her arms.
