Hey guys. I'm KR4TOS, and this is not my first story, although it does feel like that to me. I'd like to thank my friends over on Discord, namely KloseKom, Parallaxyt and Rohan Rodrigues. But the star of this show is TheFourthFate4Ever, without whom this fic would have taken much longer to actually get out. Before the main event, I'd like to just put this forward, cause I'm not going to every chapter: I do not own Percy Jackson and the Olympians nor do I ever hope to; I'll just ruin on to the story. Let's get on with it.

Welcome to Vengeance of the Just

Prologue

Epirus, Greece.

From the ruins of the Temple of Hades emerges a lone figure, clad in a black cloak. Looking around his surroundings, he walks over to a cliff overlooking the city nearby, and removes the cloth from his body.

Hidden underneath is a figure with the buff but lean body type of a swimmer that can be seen through his torn shirt, which is also stained with a yellowish pigment. A multitude of cuts and bruises are also present, and seem to be the source of the pigmentation. The biggest slashes can only be seen from behind, where two large scars run parallel to each other from the shoulder blades to the lower back. His lower body is draped with simple trousers, not unlike their modern-day counterparts, and were torn at the shins and thighs.

Jet black hair bordering on blue sprouts from his head in a messy fashion, held together only by a white hairclip which seems to emit great power . The jaw was somewhere between pointed and squared, complementing his slightly raised cheekbones. The nose was a little upturned, but could easily be mistaken for straight.

The most interesting part of the figure's features, however, are his eyes. Through the night, they appear to be pitch black with white dots in them, but turn to orange as dawn comes about. When the sun is high in the sky, it is as if the eyes reflect the color of the heavens above, and are seen as being bright blue. One could get lost in this cycle for centuries at a time.

After standing and staring at the city for over two hours, the man looks up, falling to his knees.

"I'm back."

Central Park, Manhattan, New York, USA

"NO! DON'T LEAVE ME AND ZOË!"

(Thump)

"Take care of her and the hunt, daughter."

(Thump)

"I CAN'T DO IT WITHOUT YOU!"

(Thump)

"If you couldn't, I would not have created it."

(THUMP)

*BOOM*

(THUMP)

Artemis wakes up with a start. Checking the time, which was one in the morning, she rubs her eyes and thinks about the nightmare she just had. They started a week ago, showing the same event over and over again. She frowned. These hadn't occurred for over two millennia, why would they start now?

(THUMP!)

A thunderous sound jolted her out of bed. Wasn't the thumping part of the dream, or was it coming from something in her tent? Good thing they are soundproof, or the whole camp would be woken up. Searching for the source of the noise, her silver eyes rested on her bow, which pulsed with blue energy, causing the commotion.

Picking it up, the twelve-year-old-looking goddess feels a sense of warmth and comfort enter her, and the thumping stops. Figuring out what this means, she gasps and runs out of her quarters, heading for a certain lieutenant's. Impatiently knocking on the wooden post at the front, Artemis receives a lazy "Come in." as a reply.

Entering the tent, she is greeted by a half-asleep girl of about fourteen with long black hair and copper skin. Noticing her company, Zoë quickly rubs her eyes to appear active. The auburn haired girl notes how much they remind her of his, always changing with the time of day. Currently they are black with the stars in them shining brightly.

Seeing as they are alone, Zoë sees fit to ask bluntly, "What is it, Artemis?" She wouldn't dare speak like that in the presence of the other hunters, but being Artemis's sister has its perks.

"Sister, he's back."

Three Months Later.

Montauk Beach, Long Island, New York, USA.

Normally during the fall and winter time, the beach is empty, but not today, for a couple is sitting there, with their feet in the water. The woman is nothing short of stunning, and emits an aura of warmth. She has shockingly brown hair and the same colored eyes, which were vibrant and full of life. Her clothes are normal, just a jacket over a t-shirt and a pair of jeans. The man looks like someone with great power and authority, like a king or politician. His clothes could not be more different. Having on a pair of Bermuda shorts and a Hawaiian shirt, he reminds one of a casual beachgoer or fisherman, although his sea-green eyes hold wisdom far beyond his physical age. His hair and beard were both a very dark shade of black, but not as much as our mystery man's.

As the woman starts to speak, the man tears his gaze from the sea to her. What comes out of her mouth, though, surprises and terrifies him. "I'm a month pregnant." He feels his hand in hers, being guided to her stomach.

"That's great news, Sally." Is what comes out of his mouth, but his face tells a different story. Thankfully, Sally doesn't notice.

"But I fear for my child's safety, Poseidon."

"Come with me then, I'll protect you both." And prevent Zeus from finding out, he thinks to himself. "An underwater palace will be built for you, one worthy of a queen."

"I wish I could," Sally sighed, "but I want my kid to have a semi-normal life. One not underwater." Poseidon thinks for a second. "You'll have no way to hide their scent though." He replies, hoping to get her to accept the offer. "They would constantly be hunted, and only Camp Half-Blood would be safe, where they will be surrounded by trained demigods. It's not far. I can show you right now."

Sally just smiles sadly. "I'll find a way to cover the scent. Never doubt the power of a mother." This smile is reciprocated by Poseidon before he hugs her and kisses her forehead, making a promise he knows he'll never keep.

"I'll be back."

A Few Months Later.

Los Angeles, California, USA.

A five year old Thalia Grace is playing with some toys in the lounge of a majestic house. Her lightning-blue eyes focus intensely on the airplane she's holding as she runs around the room making flying noises.

Her mother, Beryl Grace was sitting on the sofa reading a magazine with her picture on it, captioned 'Beryl Grace: Greatest of the Generation?' "Be careful Thalia, go a little slower or you'll trip on a wire."

"If I may, ma'am, why don't you convert one of the spare rooms upstairs into a playroom for the little one. It's not like we have any guests over."

A man in a tuxedo stands alert next to the sofa. This is the family butler, Maximus. It's his first job after his training and he's determined not to mess it up. It's pretty easy. He just has to keep an eye on Beryl's daughter when she's off working, and he likes the kid.

Thalia stops and gives a toothy grin to Maximus, which he gives back. "Great idea, Max. Can we, mom, can we?" She pouts and asks Beryl.

"Hm… if someone behaves herself when I'm gone for my movie shoot tomorrow, I'll think about it." Beryl replies, holding her chin in her hand as if in deep thought. "Max is going to keep an eye on you. Aren't you, Max?"

"Of course, ma'am."

A doorbell rings, alerting the group that someone is outside. Thalia puts down her airplane and looks at her mom, "Who is it, mom?"

"I wasn't expecting anyone today. Max, can you go get the door, please?"

"Right away, ma'am."

Heading down the long corridor to the entrance, Maximus opens it to find a tall, well-built man with long white hair and an equally long beard holding a bouquet of flowers. After talking to the man and telling him to wait, he goes back to the family of two to report.

"Ma'am, there is a man outside asking for both you and Miss Grace. Goes by the name of-"

"Honey, I'm back!"

So that was the Prologue. How was it? Good? Bad? Leave a review and let me know. I don't know too much about when I'll update again, but I think that two weeks are a safe bet. I'll try to work out a timetable as soon as possible so that you don't have to wait long. Until next time, Adios!
