A/N: Hello everybody! This is my second fanfiction and I have less grand plans for it than Legacies of Olympus as this will be only one book, but as for length, I don't know yet. Probably 40,000 words and up. This will be where Percy is an ancient and powerful monster that, like many mytological creatures is the child of two gods or a god and spirit, like how Poseidon has cyclops with nymphs and nature spirits and how Typhon is the last child of Tartarus and Gaia. I will be refering to original mythology for many of these creatures and events and not necessarily the Rick Riordan version. Such as the origional Otis and Ephialtes myth and not the HOO version. So, enjoy.

Diclaimer: I don't own PJO or HOO, the characters and stories belong to RR and the greeks who first told of them.

The Mediterranean Sea, 3500 BC

3rd Person POV

A cry could be heard coming from somewhere in the center of the Mediterranean sea. It was at first the cry of a woman, then it was the cry of a child. But this was not a normal cry, it was that of a beast. Of a monster. A monster so powerful, it would come to rival Typhon in sheer power. Though he is blessed with near limitless power, the son of Erebus and Gaea would have a hard life, one filled with pain and solitude.

Erebus sat next to his lover and gazed at the bundle in her arms. He pulled back the silk blanket and saw the tuft of black hair on his son's head.

"Isn't he beautiful?" Gaea breathed out, gazing at her son. Despite her feelings toward the Gods on Olympus, she was actually a very caring mother, who loved her children. It was the reason she had her son kill Ouranos, for he had cast their children, the hekatonkheires and elder cyclops, cast into the depths of Tartarus.

"What will you call him?" said Thalassa. She had given Gaea and Erebus sanctuary on her island so they could hide their child from Nyx and Tartarus. She agreed also to raise the child, as hers are grown and believe she had faded.

"Perseus. We will call him Perseus." Erebus said, unfolding one of his wings to wrap around his family. Gaea nodded in agreement, and at the sound of his name, Perseus openned his eyes. They were incredibly. A ring of solid black around the outside of the iris that murged with the grass green that went the rest of the way to his pupil. He just stared at his parents in wonder before he gave a giggle that revealed two small fangs poking out of his gums on both upper and lower jaw. He reached out for his mother and father with his pudgy arms, flexing the small wings on his back that were the same color as his eyes; black feahers with a green feather every so often.

Erebus just reached out a hand to meet his son's own and Perseus grabbed one of his father's fingers in a tight grip.

"Ow! Good gods he's strong already." He pulled his crushed finger back from his innocent looking son and healed it.

"Thalassa," Gaea said, realising his power would begin to draw attention if they didn't have protection. "Can you protect him?" she asked. The primordial of the ocean walked over to Gaea and Erebus.

"I am fading. My power wanes and I will need a successor for my domains. I can give the power to him. He may not be a primordial because he is not a giante or titan like your other children, but more like your last child with Tartarus. A monster. Erebus being the father made his power and form more concealable and focussed, but he cannot be a god of the Seas. He will have my domain under his control and he will be one with the seas as he will be one with the earth and darkness, but ichor will never flow through his vains."

Gaea looked down at her son sadly, depressed that she had sired another monster, to be hunted and feared instead of prayed to and respected.

"Once I fade and my domains pass to him, which I expect to be any minute now, he will be protected. His power will be concealed by the pressence of the sea. But should he ever leave the island I have created for him, his power will be a beacon to gods, monsters, mortals, and demi gods alike. He will become the ultimate prize. The only son of Gaea and Erebus in existence. His head will be a sought after prize." Thalassa ended gravely, the only thing either of the gods to be happy about was he would be safe on the island.

Thalassa's form began to flicker and become unfocussed.

"My time has come." she said, a peaceful expression beginning to cross her face. Then she began chanting in the ancient language of the primordials to pass her domains to Perseus. (other languages will be represented by italics).

"I Thalassa, Primordial goddess of the seas, pass my domains and power to Perseus, son of Erebus and Gaea, and willfully and peacefully fade to the Void." as she finished, a blue-green light emited from her hands and went into Perseus's chest, causing his entire body to glow with the same light. Him whimpered in fear as the glow got brighter and tried to move to his mother.

When the glow stopped, he looked at his mother, for her to gasp at the change in his eyes. The grass green had changed to a swirling and shifting sea green with the same darkness surrounding the pupil, and a spiked ring of clear blue in the center, like a crown moving from the pupil out.

She also fealt and increase in the power of the infant, and realised her son would now be safe. She looked up to Erebus and smiled, looking into the eyes of her lover addoringly, wiht him returing the look. She shifted her gaze to where Thalassa was standing and began her thank you, only to be met with empty space. She was gone.

Erebus planted one long last kiss to Gaea's forehead then one to his child's head, and dissapeared into the darkness, shadow traveling to his palace where his first love awaited, blissfully unaware of his infidelity.

Gaea just laid on the bed she gave birth on, still tired from the ordeal and nursed her son. She maybe one of the elder Primordial goddesses, but she did not have as many responsibilities as the others. Her domain was simply a state of existence and rarely needed tending. She knew that Tartarus, while not her husband, would still likely kill the child of her and one of his brothers after they already had the giantes together.

She would tend to Perseus as often as she could, but she knew that she could not be there all the time like she wants to.

3rd Person POV

A young boy, looking to be around 6 years old, was running through a plush island jungle with a long wooden spear in his hand. If you saw him you'd think he was chasing some sort of animal for food, and you'd be right. There was a boar the size of a water buffalo running just a few yards in front of him, and the boy was gaining ground. The only reason he didn't use the 3 foot long pair of wings on his back was because of the thick canopy preventing him from flying.

The boar went under a log and the boy, instead of following, ran up a near by boulder to jump off and onto the boar. He jumped onto the creatures back and stabbed the sharp end of his spear into the boar's skull. He yanked themakeshift weapon out of the boar's skull and and observed his kill. He pulled a rock knife that he made himself and began to skin the boar, then cut off the tusks. He could have used his claws to kill the boar, but he had always tried to pretend he didn't even have them. He never wanted to be a monster, and had always tried everything to be like one of the gods or titans his mother told him about. The ones people didn't hunt for glory. He hauled the bloody mass onto a large leaf to pull back to his home, where his mother should be waiting. He doesn't get to see her ofter, as she only comes once every two months or so.

He made his way through the jungle with the boar's carcus behind him and the pelt and tusks in his knapsack. Once he made it into the cave, he called out for his mother.

"Mother! I'm back!" he yelled into the cave he called home, the one he was born in just two years ago.

"Perseus." she said as she rushed to him, falling to her knees and embracing him in a tight hug he was glad to return. She planted a kiss on his dark black, windswept hair.

"Ohh I missed you so much." she said to him as she placed another kiss on his forehead.

"I missed you too mom. Look, I brought us dinner." he said proudly, gesturing to the boar's body.

"Good lords, if only you could summon food..." she said under her breath as she looked at what her two year old son had done just to eat, even if he was in a six year old body. She guessed it was just the monster in him, the primal instinct to hunt and kill for food, and not the more civil instinct of her other children that would instictually summon food. She just shrugged and sighed, patting her son's head and summoning a fire to to cook the meal. Minus well let him reap the benifits of his work.

Perseus POV (Perseus looks twelve, i.e. he ages 3 years every year)

I was sitting on my bed reading a book my mother brought a few visits ago. I was reading to pass the time and wait for her return. During each of her visits she would tell me about the world outside and what I was and how to read and write. During her last few visits she would bring me books about how to be a warrior. I was already extremely strong from my nature and my time on the island. She had been teaching me how to use a sword lately and I'd also been practicing with the books on my own.

In one visit though she brought me a book of the gods. From what I'd read, they provide for the world and have children with mortals. The books make them out to be good, but I can see past that. They are cruel. They curse mortals for being better than them, and they knock up mortals and leave them with the trouble of taking care of a child that could attract monsters and kill them both. The only olympians I have any real respect for are Hestia, Poseidon, and Hades. The others are either petty, greedy, lustful, brutish, arrogent, or blinded by their predjudices.

Only Poseidon, Hades, and Hestia seem to do their jobs and take care of their children. Every god has their flaw, except Hestia, but the two brother children of Kronos and Rhea have the most control over their imperfections. Hestia, being the pacifistic and introverted goddess just tends the hearth of Olympus and stays away from all things that may impurify her.

Finally my mother arrived. "Hi mom!" I yelled as I got up to hug her. She hugged me and planted a kiss on my head. When I looked up I saw that she had a forced smile.

"What's wrong mom?" I asked.

"Oh!" she realised I noticed her expression. "Nothing Percy." she said, sounding panicked.

"You know mom, for a primordial goddess, you're a terrible liar." I said to her. She just sighed and looked down.

"Ok Percy, I won't hide anything from you. My children, your brothers the giantes have declared war on Olympus and I have to assist them in the fighting. I don't know how the battle will end, but my children may not be a match for the gods and their children. They are more powerful than my children give credit for. I don't know when I'll see you again." she said sadley.

"What do you mean you don't know? Why can't you come back?" I asked, sounding desperate.

"I have to support my other children. They rushed into a war that they were not fully prepared for and will most definately lose if I don't help them." she said to me, looking depressed.

"I don't have long here, but I wanted to give you this." she said, pulling a long leather package from her back.

"What is it?" I asked.

"It is a sword. One day, you will be able to use it, and when that day comes, I want you to use it wisely. You are my favorite son, and your father and I had intended on giving it to you when you came of age, but now I may not have the chance." she said, placing the weapon in my hands. It was heavy, but my years here made me strong enough to hold it. I pulled back the leather wrappings to reveal a four foot scabard with a beautifully intricate handle and cross guard at the top. The scabard was made of the blackest wood I'd ever seen and had silver vines running up to the hilt in a spiraling fashion. The hilt was big enough for two hands, and it was black like the sheath and was grooved to fit fingers. Along the ridges of the finger grooves was a thin line of pure gold, and on the valleys where the fingers would go was a vein of pure silver. There was a blood red jewel on the pommel that oozed a red and black mist, and eminated darkness and despair. The cross guard was gold with silver trimmings, and was flat where the would meet the handle and spiraled the rest of the way out from the center to end with two spikes going up and down (the end of the crossguard is like barbed wire fence where it spirals and ends with two points, but the spiral is one piece of metal and not two twisted together). On the flat part the word "Darkspire" was written in greek.

I grabbed the handle to see it was still a little big for me, but the sword seemed to humb at the touch of its master. I pulled the blade out of the sheath to reveal the four foot blade in all its glory. It was perfectly balanced and beautifully made. It was celestial bronnze on one side and stygian iron on the other. It was leaf shaped and so sharp, it made razors look about as dull as the stone it was sharpend on. The sword felt powerful in my grasp.

"This is probably the most deadly weapon in existence. The only contendor would be Kronos's syth or and of the primordial weapons, but I was able to pull some favors. This blade is the combination of my brothers and nephews domains. None of them knew I was making a weapon, but they gave me the supplies none the less. The jewel on the pommel was from Tartarus from his own thrown and will make anyone see their worst fears if they touch it or attempt to wield the blade. Even Phobos and Deimos would cower. The handle is stygian iron from your father, lunar silver from Selene, and Cronisian gold from Cronus, my brother. When wielding the blade your enemies will move slower because you will be slowing time around you. The same gold and silver are in the cross guard. The blade is a combination of stygian iron and celestial bronze. You will be able to collect the souls of your enemies in this blade, lest they learn they never should've attacked my son." she said, the last part mostly to herself.

"Why did you make me such a powerful blade, I can take care of myself." I said indignantly, now afraid I ccould hurt someone seriously and never be able to take it back.

"I just want you to be safe." she said getting teary eyed and hugging me.

"But I thought I was safe on the island." I said.

"You are, but as your power grow and you get older. Eventually your power will not be able to be disguised by the island and people and demigods will flock here because you are here. You are not a god, but a monster. And people will hunt you for glory. With this blade, no one can hurt you while I'm gone. I have to go now, but know that will always love you." she said, hugging me as if she would never get another chance to. Little did I know that she wouldn't.
