Chapter 0: The Prologue

The sky darkened. The winds howled. The ground shook. It was the end.

A blast of thunder threw Zeus far into the battlefield. The Giant, Porphyrion, the King of the Giants, laughed triumphantly, sneering at the Demigods charging at him.

"Pathetic!" He roared, throwing flashes of lightning across the grim battlefield. The Giant King had made his stand under Gaea.

"Is this your hero?!" He snarled, slamming Jason to the ground with his shield. "The Pride of Jupiter?!" He mocked.

Percy clenched his jaw. Riptide hummed against his coarse hand. His gaze darkened as the storm around Athens picked up the pace. The demigod stalked towards Porphyrion, glaring murderously.

Poseidon summoned his trident from the fading corpse of Polybotes, the bane of the Sea God, following behind his son. His eyes flashed dangerously, reflecting the storm in his son's eyes.

"Porphyrion, how about you come do that to us!" Percy called, brandishing Riptide.

Porphyrion growled, letting thunder crash from the sky across the battlefield. In an instant, smoldering bodies littered the hillside. The stench of death was almost overwhelming, and quickly made its way to unnerve Percy.

And unnerve it did, as the Son of Poseidon lost his ability to think, switching to rely on his primal instincts. He threw Riptide recklessly, and with the force of the storm behind the blade, he managed to pierce Porphyrion's breastplate. It did its job as the Giant lurched backward, roaring in agony. The small victory was short-lived, however, as Porphyrion launched his spear at the Percy, Riptide falling to the dirt.

Poseidon leaped in front of his son, raising his shield just as Porphyrion released his spear. He took the brunt of the blow, sliding backward under the force of the Giant. In addition, the immense power of the spear cracked Poseidon's shield.

"That's it?" Poseidon challenged, raising himself up to his full height.

The now weaponless Giant smiled easily. "You have no idea, child," he answered. His hands began to glow with an ethereal light. Suddenly, he slammed his fists down into the ground.

The Earth trembled, and even the Earthshaker himself couldn't stay on his feet.

Thunder coursed through Porphyrion's entire body, sparking at his fingertips. His white eyes burned with immense power. The Giant towered over everyone, including his allied Giants and the gods themselves.

He snapped his fingers, and suddenly, storm spirits, werewolves, and Earthborn materialized around him.

"I am the firstborn of Gaea!" He roared, "Fear me!" Ozone leaked from his aura, seemingly suffocating Percy, who was left unarmed in front of the behemoth.

"Porkhead," he stated calmly, "I don't think I like you very much."

Needless to say, the Demigod was thrown off the mountain in an instant.

Yet, the Earth rose to call, raising a platform at his whim. He caught himself on the slab of brown rock. It hurt, but at least he was alive, well, for the most part.

Poseidon fell on his knee, drained from the fight with Polybotes. As he struggled to rise a supporting hand was on his shoulder, as he looked up to see his brother, Zeus, King of the Gods.

"Brother," the Sky God rumbled as he helped his younger brother rise, "You seem to be in need of assistance."

Poseidon ignored him at first, checking over to where his son was launched like a rag doll. He quickly found him spitting out dirt and blood, satisfied, he turned back to Zeus. "If you think I am too prideful to receive help, then you have the wrong side of the family. Take arms, we have a pest to deal with."

Zeus nodded but paused to look at his son. Switching to his Roman form, Jupiter addressed Jason with a strong voice, "Do not interfere, yet prepare for the finishing blow. My brother and I will weaken this excuse of a king, yet we will need you to truly bring him to his demise."

Looking a little miffed at being told to sit on the sidelines, Jason gave a stiff nod and watched as his father returned to his greek form and summoned his legendary Master Bolt. Poseidon had snapped his fingers, though his trident was already in his grasp, confusing the auditing demigod.

Jason watched as both immortal brothers worked together surprisingly well, considering how the myths spoke of often they bickered. They covered each other's blind sides well, and each strike either one landed was precise and efficient.

Though he wished he involved in the battle against the Giant, even though he was quickly proven to be outmatched, Jason couldn't help but feel honored to watch such a glorious battle.

Percy was on his fours as he tried to regain his bearings, "Come on, Percy," The Demigod muttered under his breath, "That was stupid, even for me. I can hear Annabeth scolding me now." He managed to sit up and survey the battle from his vantage point.

Immediately, he wished didn't. It was gruesome, demigods being picked off like the food at a buffet. It gave him the strength to get up.

I can't let any more demigods get killed.

But, of course, with Percy's Fate edition luck, he watched in dread as a young Demigod, Garen, a son of Apollo, was suddenly entrapped in the earth. Percy watched in dread as Orion kicked Apollo out of the way and took aim at the entrapped demigod, no doubt alerted by Gaea. The arrow flew true, and Percy cowardly turned away, not wanting to see the death of the little child.

Anger once again found a home in Percy's gut, as sea-green eyes darted across the battlefield to see where he would be most helpful. He found blond curls and found Annabeth in an intense battle with Enceladus.

Percy quickly whistled for Blackjack as he looked back to where his father was fighting to find his Riptide, but, as soon as he thought it, he felt a sudden increase of weight in his pocket. He smiled mischievously and pulled out the ballpoint pen.

Blackjack landed next to Percy, "Hey Boss, you whistled?" The pegasus wore black armor.

"Hey Blackjack, think you could fly me over to Annabeth?" Percy asked. He knew the pegasus would answer yes so he hoisted himself onto Blackjack's back.

"Of course, Boss! You don't even need to ask." Blackjack took off into the skies with Percy hanging onto his mane. It took mere seconds before he was already closing in on Enceladus.

"Blackjack, I'm going to jump off, attack from above. Go see Clarisse or the Stolls, they could probably use you."

"Alright, Boss. Just remember my donuts when this is all over."

"I appreciate the confidence buddy!" Percy tapped his wristwatch, fully refurbished by Tyson, and jumped off of Blackjack, gliding over to the bane of Athena. He placed his shield in front of him and rammed the Giant in the head toppling him over.

"Hey, enchiladas! Hands off my girl!"

The Giant flew backward, crashing through rows of monsters behind him.

"Hi, Annabeth," Percy waved, smiling brightly.

The daughter of Athena broke her serious composure. "Hello, Seaweed Brain," she answered, letting herself relax for a moment.

"Jackson!" Enceladus growled. "You cannot defeat me so easily, Demigod! The Gods managed to trap me under a mountain eons ago, but they killed me. It humors me to think you can challenge you. You are just a litt—,"

"Shut up."

Athena tightened her grip on her golden spear, letting it glow with energy. Wounds were scattered across the Goddess' arms, but she didn't look any less fearsome.

Enceladus narrowed his eyes, glaring daggers at the Goddess of Wisdom. He raised himself up to his full height, looking down upon Athena. Only the three major Giants Polybotes, Alcyoneus, and Porphyrion bested his height. Obviously, Athena was nothing compared to the enormous deity, but Athena never wavered.

"Tell me something, child." Enceladus turned his gaze to Annabeth, making Percy get into a defensive stance. "Are you proud? Is the feeling of immense gratification overflowing your demigod spirit? Fighting alongside your mother, I can smell the euphoria off your skin."

Athena took a step forward, ready to throw her spear at the Giant, but her daughter spoke up, "You're going to die Enceladus. You belong in Tartarus."

He ignored the defiant remark and smiled evilly. Percy slightly shivered at the sight, quickly comparing it to Athena's. Great minds act alike, I guess.

"I was once proud too. I thought the Gods could never defeat me," he paused at his bane's snicker, "Of course, I was humbled, as I struggled for eons under the mountain they crushed me with. Imagine my situation, being half-conscious with pain being my only feeling for millennia."

"You probably deserved it," Percy interrupted

"What's the point of all this? Why are you telling us this?" Annabeth snapped.

"Because my experiences taught me patience, girl. It taught me not to act rashly. Now, I've clawed my way back with the help of the waking Earth. I assume you have made acquaintance with her." Enceladus then picked up his spear, which was taller than a flagpole, and pulled his arm back.

"Percy, Fight with my mother!"

The Demigod looked back in shock, "No way, we work better together."

In response, she pulled out a familiar baseball cap, "I got this, remember? Put aside your differences today, Seaweed Brain. We have a war to win." She slipped on her cap, disappearing from view.

Percy looked back towards the Olympian, who surprisingly wasn't even looking at her opponent. "Athena! What are you—"

His voice faltered as he finally noticed the Earth that was trying to drown the goddess. Athena's face didn't seem frantic, but her actions betrayed her. She stabbed at the earth, which was slowly encasing her, but her efforts were futile.

"And look how my patience rewards me! Athena, you may have killed some of my brethren, and I might die today as well. But now, you enter Tartarus with us! Gaea is nearly awake. And don't think because we have not even traded blows, that I will not kill you while you are immobile."

He pulled back his arm, prepared to launch, and Percy's mind went into overdrive. Throwing away his sword and shield, he runs in an all-out sprint against time. And luckily, for the first time in a long time, he reached Athena. He tackled her to the floor, which pulled her feet out of the quicksand, just as Percy heard the spear whizz past his ears.

"And look! My spear has hit its mark!"

Percy quickly hopped off of Athena's body and looked her over.

"Perseus! How dare you look—"

"I'm not looking at you like that, my Lady. I'm just checking if he has hit you. He didn't, but he didn't hit me either. So, who did he hit?"

Slowly, Percy felt his heart drop into his stomach. He turned to where he last saw Annabeth and only saw the spear coated with crimson blood. He watched that spot, praying to every God he could think of, hoping that it was just a flesh wound.

His prayers weren't answered.

Annabeth's body flickered into view, lifeless and empty.

The world stopped, the noise silenced, and all thoughts became pointless. For once, Percy didn't try to be the Hero. He didn't try to stay strong. He simply couldn't. Tears ran freely from Percy's eyes as he crawled over to Annabeth.

"Annabeth?" Percy whispered shakily. He closed his eyes, refusing to see her body marred by Enceladus' spear.

Storm clouds rumbled in above, thunder growling in between the nebulas. The battlefield froze, both sides stopping their fighting to see the cause of the sudden uproar. As the side of the gods looked upon their Savior of Olympus, most knew what had transpired.

Annabeth Chase was killed.

Athena had seen many of her children die. Some of them died for her and the goddess always honored them. But watching Percy break down for her daughter, her most favored daughter,

For the first in eons, Athena was at a loss. She didn't know what to do with the emotions flooding her at the moment.

The Wisdom Goddess watched with trepidation as Percy trembled, and forced herself to become emotionless if only so that their most trusted fighter doesn't lose their bearings.

"Perseus, you must calm down, lest you fall as well," Athena warned, stepping closer to the Demigod.

"And the first of the Seven falls! Come demigod, that you may join your bastard lover in death!" the bane of Athena challenged.

At that moment Enceladus sealed his own fate.

Percy froze, and Athena knew further efforts were useless. His eyes darkened as he stood. His aura took on an actual glow and flashed dangerously. Riptide glowed profusely, and the Earth trembled.

The Demigod charged Enceladus like a madman. With each step, the storm above him intensified. Nothing mattered anymore. They all needed to die.

Enceladus was intelligent, to say the least, but he didn't take account of Percy Jackson.

And he will teach these thoughtless Giants fear.

A/N: This is one of two stories that I'm working on with Xx_Anaklusmos_xX. They're really great writers. Honestly.

This story is gonna be different from a lot, which is something I love. More likely than not, you will not see much of Olympus. Based on the summary, we just told you this entire story is under the sea in Atlantis. You don't see an adult Percy in the seas much do ya?
