FOR THOSE WHO HAVE ALREADY READ THE FIRST TWO CHAPTERS: I have added and changed some things in the first two chapters to make it longer and more interesting so read them first.
Disclaimer: I do not own Percy Jackson and the Olympians.
The Prologue is set five years after The Last Olympian. All of the hero's of the Second Titan War have been given Immortality: Percy, Annabeth, Nico, Travis and Connor, Katie Gardner, Clarisse, Will, Tyson, and Chris. And Grover was immortal because he was the new Lord of the Wild.
Prologue
Percy
It has been three years since Percy was given immortality. He caught Annabeth cheating on him with this new kid named Mark, Son of Poseidon. Everybody loves him, he completed one quest and it's like he is the greatest hero ever. He is the best fighter at camp (well except for Percy but everyone forgot about him). The only ones that haven't forgotten about him were Nico, Grover, and Thalia, even his own father forgot about him when his new son Mark came. But Thalia is with the Hunters, Grover was off gathering new demigods to bring to camp and also being the Lord of the Wild and Nico now just stays in the Underworld most of the Time. Then the gods offer Mark immortality and Percy finally has enough.
He leaves camp and he doesn't plan on coming back. He Iris-Messages Nico and he even leaves Riptide behind (because he is forcefully leaving it behind it stays). And of course guess who keeps it, Mark. A few weeks after he leaves camp Chaos, the creator of the universe, finds him and wants him to join his group of soldiers called S.O.C (Soldiers of Chaos) a group of soldiers who travel the universe to protect the innocent and vanquish evil. Chaos choose him as his personal Assassin. Percy learned fast, being taught not just how to fight but how to hunt, how to survive, but most importantly how to kill.
No one but Chaos knew his name. The other soldiers of the S.O.C didn't know who he truly was, only Chaos. He never spoke unless he needed to. He took commands from no one except Chaos himself. Were ever he went death followed.
He wears a black hooded Assassins cloak with sea green trim. Perfectly engraved silver armor, silver gauntlets with engraved silver hidden blades (that pop out when he wants them to), and black assassin pants on. Knee high boots on with engraved armor on the tops of the boots that are blessed to not make a sound (If you have played Assassin's Creed Brotherhood then picture Altair's armor and you kind of have an idea of it). A beautiful silver four foot long double edged sword strapped at his sight. Duel blade two foot long blades strapped on his back. Throwing blades strapped on his belt. Percy has even mastered the Bow and Arrow and has a beautiful bow that would rival Artemis' Bow. The bow automatically reloads just like the hunters bows.
The shocking thing that he wore was a beautifully designed mask that covered half of his face. But people never knew the real reason why he wore the mask. Some thought it was to hide his identity; some thought it was to make him more seem scarier. But the real reason was because it hid three slashes that went across the right side of his face, with the middle of the three slashes going right across his right eye. I know what you are thinking. Doesn't he have the Curse of Achilles? Yes, he does. But the cuts came from an ancient beast that not even the curse could protect him from.
There were two things that the mask couldn't cover up. The first was a patch of jet black hair, the same color as his hair, on his chin. And the second was those sea green eyes that he was some famous for, but now they were different. They were deeper and harsher. You can see all the death and pain from the past 500 years that he has seen.
Camp
Annabeth and Mark dated for about two months and he was offered immortality. She was so happy. Then one day she saw Mark kissing some Aphrodite girl and they broke up. After than she wanted to find Percy and tell him she was sorry and get back together with him. But she couldn't find him. She told Chiron and all the gods that he was missing and Poseidon was devastated after losing his favorite son. Then finally Nico told them what Percy said and they went out to search for him but no one could find him. Thalia was mad and hurt because she hid have a secret crush on him but would never admit it and he was like a brother to her. Every five years the Gods and the Camp counselors would hold a meeting to hear of any news of the great hero but no luck. All they know is that he didn't die because Hades would have known.
It has been five hundred year since Percy left. He has changed. He is not that happy care free kid that everyone else used to know. Now Gaea along with the Titans are rising once more and the Gods fear that they won't be able to win this one.
There is the Prologue tell me what you think.
