Okay, so I absolutely couldn't stand how awful I thought this prologue was, so I rewrote it to a standard I thought was better. The content didn't change, I just made it sound more professional. I promise this will be the only time I rewrite something.

Here goes my first Percy Jackson fanfiction. Hope you enjoy. This is rated M for smut/sex/porn in future chapters, I'll give a heads up on those chapters, and possible mpreg; not too sure where this story could head.

This is just the Prologue, but it's majorly important for you to read anyway. The good stuff starts next chapter. If you'll just suffer through this part and read next chapter, I promise it gets better.

This is Percy/Nico with other pairings as well, but the smut will be Percy/Nico. Anyway… I'm rambling, so PLEASE review and tell me if it sucks or is good, and follow if you like it! Here's chapter one…

Prologue

Once upon a time, in lands far away, there were three kingdoms. These kingdoms had been engaged in bloody combat for over four hundred years, so long that no one was quite sure when the war actually started or what the reason for its instigation even was.

The most well-known and wealthy kingdom was Olympus, ruled by Zeus, the King of the Skies. His kingdom rested high atop the Macedonian mountains. Its extraordinary iron walls and stunning buildings stood proof of Olympus' domination over architecture of their time.

On the other side of the world, known for its forges, artisans, and merpeople, lay the beautiful kingdom of Atlantis. Located on the ocean floor, the great subaquatic nation was decorated with the most elaborate coral designed edifices. Poseidon, the King of the Seas, ruled not only this magnificent nation, but all oceans and waterways, making it difficult for the other nations to travel the seas during this war time.

Finally, deep far away from the other countries, on the edge of the world itself, was the dark kingdom of the Underworld. Not much was known about its mysterious lands, for the Underworld was a barren wasteland, toxic to Atlantian merpeople and unpleasant to Olympian citizens. Many who ventured into its borders did not return, making the only known facts the rumors passed down over generations. Many believed Hades, the King of the Dead, to be a major reason the war was still going on. That is, until he became the reason for peace.

…

One fateful day, during the heat of battle on the outskirts of Atlantian shores, the forces of Hades and Poseidon battled for their lives. The clashing of swords and the screams of the wounded filled the air. On one side of the conflict, Lord Hades was charging an oncoming swarm of Atlantians. His Stygian Iron sword clanked slashed each man like it was nothing. Nevertheless, as easy as the battle attested to be for him, it proved to provide a distraction.

Hades was too busy in his confrontation to notice the stray arrow headed in his direction. However, his daughter Bianca, a great huntress and incredible warrior, did notice the lone projectile, and threw herself in front of her father, taking the arrow directly to her heart and fell to the ground, dead.

Meanwhile, on the other end of the battleground, the King of the Seas was engaged in his own skirmish. So busy in fact, that he failed to see a squadron of Hades' soldiers approaching from behind. Poseidon's own son, a half-cyclops named Tyson, intercepted said attackers, but was overcome by a blow to his skull, and in seconds he joined Bianca in death. With his pronged trident, Poseidon pierced the remaining attackers and joined Hades in screams of heartache. Distraught over their losses, the battle was over.

…

The next few weeks were occupied with burial after burial. Out of respect, Zeus recalled his troops to allow his enemies to mourn the loss of their children. As time went by however, Poseidon began to sink into a deep depression. He longed for the end of this pointless conflict. In a moment of sheer hopelessness, he sent a courier with a letter to the Underworld, begging Hades for a truce. He hoped that if the two of them could end their conflict, Zeus would follow suit.

Upon receiving the letter, Hades rejoiced silently. The Underworld had suffered more losses than any, and Hades wished the war over as much as the others. Nevertheless, signing a peace treaty with Poseidon would not prove as effective as the King of the Seas foolishly hoped. Paper was just paper and a treaty could be broken. So Hades came up with a plan; an arranged marriage.

Besides his recently passed daughter Bianca, Hades had two other children: a second daughter named Hazel, and a son named Nico. If he had recalled correctly, Poseidon had two children as well: both of them sons, Triton and Perseus. But Triton was already betrothed, leaving Percy as the only suitable candidate for this marriage.

The King of the Underworld wrote a letter of reply to Poseidon. If Percy would agree to marry either Nico or Hazel and live in the Underworld with his betrothed, a permanent truce could be placed between their two kingdoms. When the King of Atlantis received said letter, dread filled his heart. For peace to be achieved, he would lose another son forever. Yet the need for harmony was greater than any loss Poseidon could experience, so he reluctantly agreed to Hades terms and informed Percy of his fate.

…

When news of this alliance reached Zeus, he became panicked. If his two foes united against him, he would certainly be defeated. So the Olympian ruler plotted against his enemies. He decided to send his son Jason to the Underworld to spy on the Atlantian prince. If Hades wanted war, Zeus would give him war…

Okay, so this was a SUPER short chapter, but that's just because it was giving the background to the story. Next chapter will be much longer and will actually have POV and a good storyline. It shouldn't be too long until next chapter comes out. Please review and let me know what you think!

And sorry that I rewrote it. I just saw that a lot of people would read this chapter and then not read the next and I got paranoid. I won't rewrite anything else.
