Chapter 1

The hooded figure slashed at the last Cyclops, completely turning it into dust. He looked at his stopwatch, it read 4.06 seconds. He heaved a sigh, New record, he thought.

"Nice job as always, Omega," a scruffy voice praised.

The hooded figure, Omega, capped his trusty bronze sword, Riptide, shrinking it back to its pen form. "Thank you Master," he replied, his face emotionless.

Now, how did this guy get Riptide you say?

It belongs to the greatest hero to ever live you say?

Simple, Omega is this so-called hero; before he was forgotten.

Betrayed.

Abandoned.

That happy and easygoing son of Poseidon is long gone. He is replaced by a merciless, cold-blooded assassin, very loyal to his Masters.

A voided expression never leaving his face, the assassin longs for an ichor-stained blade.

You'll never know what hit you, he thought, chuckling darkly. Just you wait, soon enough; I'm going to get my revenge.

And it all started when the gods decided to award their heroes, five centuries ago.

*Flashback - 2 months after the Giant War*

It's been 2 months after the Giant War. Gaea is defeated, and the Greek and Roman camps are living in peace. Octavian learned to trust the Greeks when Leo Valdez and Will Solace saved his sorry butt from getting whooped by a bunch of Canadians.

It was a normal day, but not for the Savior of Olympus, Percy Jackson. He was going to propose to Annabeth in a picnic date. He got Athena's approval considering he got out of Tartarus with Annabeth, both of them safe, and single handedly bested Gaea. But then he noticed something.

He was being avoided. Ignored. People were getting nervous around him. They tend to leave immediately when he walked up to them. Even Annabeth was ignoring him.

And as usual, he doesn't know why.

He continued to the Athena cabin but was stopped by a bright flash in front of him.

Percy averted his eyes and when he looked, he saw a tall middle-aged man, with sandy blond hair and blue eyes, holding a three-foot long oak staff, dove wings sprouted at the top, and two full sized green snakes intertwined around it.

There stood Hermes, god of messengers, caduceus in hand, in all his glory.

"Lord Hermes," Percy greeted, bowing slightly. As much as he hated being formal, he doesn't wish to be blown to bits.

"Percy, I come with a message. Call all the cabin counselors to the Big House," the god said before flashing to the said building.

He thought about what made the usually happy-go-lucky god serious as he made his rounds, telling the counselors to head for the Big House. He then followed suit after the last one walked off.

Percy got there only to find all the counselors disappeared. "Where are they, Chiron?" he asked his teacher.

"Lord Hermes mentioned something about giving the heroes immortality for their help in the Giant War, and hope to be immortal trainers of Camp-Half Blood and Camp Jupiter," Chiron replied, shocking the demigod in front of him.

"But Chiron, why didn't they include me?" Percy asked, "Where are they?"

"The reason, I do not know of," the centaur said sadly. "But they are most certainly at the throne room in Olympus."

Percy just nodded with a blank expression on his face. He quickly ran back to his cabin and got out a drachma. He made a mist and tossed the drachma into it.

"Oh Iris, goddess of the rainbow, show me the Olympus throne room."

The mist shimmered into an image of the throne room. Hestia and Hades were at their thrones. There was a cocky looking boy about 17, sitting on the foot of Percy's father's throne. The other counselors have this new aura around them, they accepted the gift. Right now, Annabeth was standing confidently, facing the gods.

"Annabeth Chase!" Zeus boomed. "Will you accept the gift of being immortal?"

Annabeth looked unsure.

"You will be forever the Architect of Olympus, and an immortal trainer at Camp-Half Blood."

She began to have a look of doubt on her face.

"And you will be the lieutenant of your mother, Athena, if you wish," Zeus finished.

Of course she'll not accept that, Percy thought. She still has her Seaweed Brain-

"Yes."

Doubtful expression gone, she said one word. One word. It all took just one word to freeze him. That one word from the daughter of Athena, who he turned down immortality for, who he treated like a goddess, who he thought would never leave him, shattered his heart instantly. He wanted to die, but he certainly would with the next event.

"Now, what will we do with my disgrace of a son?" Poseidon asked.

Percy felt tears well up in his eyes.

Am I a disgrace? he thought miserably, Is what I've done for them not enough?

"Father, I suggest you either banish him from Olympus and the two camps, or kill him, or send him to Tartarus," the boy at Poseidon's throne said, standing up. "He could be a threat considering he spied for the enemy."

Anger started to boil up inside Percy. The boy was also a demigod son of his father, and he didn't even know him! His father let him carry the two great prophecies on his shoulders, while this guy had all the time in the world to just sit back while he was out fighting monsters. And now, they accused him on spying for Gaea!

"Duke, as much as I wanted to do what my favorite son suggested, we must ask for Zeus' approval first," his father said, making him flinch. He was the only one called a favorite son of his father, and now they replaced him like he didn't exist.

Shouts of protest came from the other gods, namely Aphrodite, Apollo, Artemis, Hephaestus, Hermes, and surprisingly, Hades.

Zeus thought for a while and said,"Very well. Ares, bring the boy here in chains."

Before he could reply, Percy whispered, "No."

It was barely a whisper, yet everyone in the throne room heard him, turning to the Iris-message and gasped. Annabeth looked horrified.

She became afraid of how long he had been there. She was afraid that he would get angry at him for accepting immortality. At least when he became angry, she knew she could move on. Besides, that other son of Poseidon, Duke, looks strong and cute.

But she never saw anger. She saw sadness. And almost immediately, she felt a pang of guilt shot through her heart. She felt guilt, regret, sadness.

She wanted to kill herself for being so stupid. She broke the heart of the man, the great man, her great man, who always has her back. The great man who treated her like a goddess, the great man who turned down immortality for her, and yet, she broke him.

She felt like half of her soul broken, half of her soul being Percy. She can't imagine herself living without him, now that she has already done the wrong thing. She chose power and immortality over him, who instead, chose to love and be a loyal lover to her.

She failed him.

Getting out of his shock, Ares flashed out. The Iris-message blurred and dissolved just as the war god came back with the son of Poseidon in Celestial Bronze chains.

This time, he looked furious.

Percy glared murderously at his father and his uncle. Zeus spoke up, "Perseus Jackson, you are accused of spying for the Earth mother Gaea. Are you guilty of this accusation?"

His eyes turned to his half-brother, who flinched under his glare. He looked back to glaring at his uncle, "Lord Zeus, accusing and knowing are different. You of all people should know that."

Zeus became angry. "You dare defy me? Fine!"

He summoned his master bolt and pointed to Percy. "Any last words, Perseus?"

He swallowed and stood straight. He turned to Hestia.

"Lady Hestia, thank you for being there for me. I will remember you." Hestia smiled fondly at his words, as Percy turned to Aphrodite.

"Lady Aphrodite, thank you for defending me. Looks like your love story didn't end up well." She smiled then frowned at the mention of her love story. She slumped back on her throne.

"Lord Apollo, thank you as well. I would not forget your haikus," Percy said, earning a sly grin and a wink from the sun god.

He turned to Hermes and said, "Lord Hermes, thank you." Such simple words made the god of mischief grin and give a thumbs-up.

"Lady Artemis," he said, the said goddess smiling at the first good man she had met in millennia. "Thank you for standing up for me. I will remember you." Percy grinned at her then turned to the god of fire.

"Lord Hephaestus, thank you. I now understood what you mean from two years ago, and I will keep that in mind," he said, remembering their conversation in Calypso's island. Hephaestus smiled sadly at him and gave a slight nod.

"Lord Hades," Percy began. The lord of the dead stared at him expectantly. "I-I don't know why you did this but.. Still, thank you. And please," he added, earning a confused look. "Don't tell Nico of my faith. I won't have you swear for it's your choice. You would know where that leads." Hades nodded solemnly.

Percy turned to everyone else, his anger visible again. "And as for the rest of you, heed my warning." He leaned closer forward.

"You gave me a choice: to leave you forever, with no dignity, no pride, no hero. When I come back, you'll be receiving eternal torture you deserve, and I will have my pleasure doing it personally. I swear this on the river Styx. Have fun dying."

He grinned evilly and got out a small black box, threw it to the ground, and stepped on it furiously. He then mist-travelled out of the throne room before anyone could stop him.
