Disclaimer: I do not own the book series Percy Jackson or Heroes of Olympus. Rick Riordan does. Enjoy reading!

And one thing before you start reading this story, the myths here are not based on real myths and are mostly just made up. Just wanted that to get out of the way.

Prologue – Where it all started

POV: 3rd Person

Perseus ducked underneath a sword and rolled to the side and quickly stabbed a monster in the back who wasn't quick enough to react. He looked to his left and jumped out of the way of a spear which flew pas his ear, barely hitting him. Without wasting time, he turned around and stabbed a hellhound in the side who tried to catch him by surprise. He then ran towards a cyclops, the one who was responsible for the spear, which was thrown at him, and cut the monster's head of. The ground surrounding Perseus was covered with golden dust from all the monsters.

Perseus fought like a beast, slashing and cutting through monsters like it was nothing. His strikes were precisely and deadly, leaving death and destruction in its path. The way he fought would make a person think twice before attacking him. Sadly, these were monsters and monsters weren't exactly known for their brightness.

Suddenly, a cry rung through the battlefield. Perseus quickly stabbed a hellhound and look up towards the sound.

His blood boiled when he saw his mother, Selene, covered in blood with big gash on her side and his uncle, Helios trying to protect her from Typhon, also known as the Father of all Monsters. Perseus rushed over to his mother, a tornado surrounding him keeping the monsters away.

Perseus crouched down next to his mother with tears in his eyes and looked up at Helios who looked Perseus straight in the eyes and said, "You take care of her, I will get that big boy over there." He nodded towards the direction Typhon, before he let out a battle cry and sprinted towards the Father of all Monsters.

Perseus looked down again at his mother and saw her breathing heavily.

"Mom? Please hold on.." He told her as he put his hands on her side. His hands started to glow silver and he closed his eyes, concentrating on healing his mother. After a couple of seconds he opened his eyes only to see that it didn't work. He placed his hands again on her side and tried again, but before he could he felt a hand being laid on his hands. He looked up at his mother's silver eyes.

"P-Perseus, please… d-don't waste y-our energy o-on me," she let out a shaky breath," My t-time has come.. but-but before I-I go, please promise m-me something." Her voice was trembling and it was clear that she was trying to hold on to her life.

"N-no mom! I can heal you! Please hold on." Perseus' hands began to glow again and he pushed all his energy into trying to heal her, but once again it didn't work. He then felt a hand under his chin and raising his head, so he looked into the eyes of his mother.

"P-please Perseus," Perseus' eyes were by now filled with tears and he was freely crying. He slowly nodded as he looked into his mother's pleading eyes. He didn't want to lose his mother yet. You see, Percy was only about a three hundred years old which is very young for a Titan. He was about as old as an eleven-year-old human.

"P-promise me you.. y-you will-l protect the next h-heir of the moon." Perseus knew this moment would come at some point, his mother had trained him for this, to become a guardian of the moon. But he didn't expect it to come so soon. He wasn't ready at all.

"I-I promise mom." Perseus said silently. But his mother wasn't happy yet.

"T-take the o-oath." She said. Perseus knew what she was talking about. Already when he was a little boy his mother had told him about this oath and that he had to take it at some point when she would fade. Perseus hadn't taken it very seriously at the time because he knew how powerful his mother was and she wouldn't just fade away. Perseus certainly didn't expect the time to come so soon already. But Perseus nodded as the words of the oath came to his mind and he stood a little straighter. Tears were still pouring out of my eyes.

"I-I, Perseus Achilles Jackson, swear solemnly on my life, soul and body and everything that I have that I will protect my charge to my dying breath;

that I will support and defend my charge against all enemies and foes;

that I will obey the order of my charge and the orders of those appointed over me;

that I will take all the responsibilities of being a Guardian for the rest of my life.

This, I promise on the river Styx, may she claim my soul in the afterlife." Thunder boomed in the distance, sealing the oath and I felt a new power flow through my blood making me feel more powerful.

I looked back at my mother and she looked at me with a smile and a look of peace crossed her face when the oath was sealed. She then gave me one last look and said in a small voice, but it sounded as clear as day in Perseus's ears.

"I love you so much my little guardian, I always will," Before she closed her eyes and here breathing lessened before she slowly disappeared and faded away.

Perseus looked at the spot his mother once was and couldn't help to be angry. This was all that stupid Typhon's fault. He looked at where his uncle and Typhon were still fighting, but to his horror he saw Helios lying on his stomach disarmed at the ground. His bow laid a few feet away and he tried to reach for it, but it was too far away. Typhon had his sword raised up in to the sky and was ready to give the final blow. Perseus sprinted towards his uncle trying to save him as Typhon's sword came down.

"NOOOOO!" Perseus cried out and pushed himself to run harder, but he had no energy left and was already running on nothing. Time seemed to slow down as Typhon's sword came down and Perseus saw Helios look up at him, a look of sadness in his eyes. Helios nodded at him and mouthed the words "Take care," at him and then the sword made contact with Helios body. Perseus felt helpless as he also saw that his uncle was also starting to fade away.

Perseus couldn't take it anymore. His body was shaking with anger and he cried out, his voice full of pain and anger, and before he knew it, he was charging the 2000 feet giant, blinded by his rage. His body was glowing silver and his once green with silver eyes were now fully silver, glowing with power and they looked to be on fire.

Looking back on it, it was a stupid idea to even think about fighting Typhon on his own. But Perseus couldn't help it, he just lost his mother and uncle because of this monster.

Perseus looked behind Typhon and saw a big pile of stones behind him and behind that a giant mountain. He smirked as his brain formed a plan. It was the stupidest plan that ever existed but as he as Perseus saw no other option he might as well try this. He just needed to get high enough and put all his energy in the final blow.

Typhon saw Perseus charging him and smirked, "Ahh puny Titan! You think you can take on me?" Typhon let out a booming laugh," Muahahah! you were not even able to protect your weak mother and uncle." Perseus only became angrier because of this and ran towards the Monster's snake feet. Once there he took out his other knife and climbed one of its weird snake feet.

Typhon who now felt like someone was pinching his legs, leaned forward and looked to see the ant of a Titan climbing his leg. He let out another booming laugh and grabbed the Titan with one of his hands and raised him towards his face and started crushing him.

Perseus tried to wriggle himself out of Typhon's hand, but his grip was to strong and he couldn't breathe. Perseus felt his body slowly going numb and he felt helpless. One of his arms was rotated badly to the side and Perseus' ribs where crushed by the force of Typhon.

Suddenly, Perseus felt himself getting mad. This wasn't how he would die. He wouldn't give in so quickly. Typhon would pay, he would pay the price of killing his mother and uncle. Perseus started to shake uncontrollably and he saw his body starting to glow. He started glowed brighter and brighter.

Typhon was amused as he saw the boy trying to wriggle out of his grip, but his smile dropped as he suddenly saw the boy glowing brighter and brighter. He became so bright that the titan had to shield himself with his other arm. He dropped the boy as to get the light away.

Perseus felt Typhon's grip lessened and with his sword hand he stabbed one of the gigantic monster's fingers and held onto his sword so he wouldn't fall to the ground. As Typhon pulled his hand back Perseus jumped out of his hand and felt suddenly immensely powerful. Mid-air he put his right foot forward and Sparta kicked Typhon in his chest. At the same time a golden arrow stuck the giant in the chest and it exploded.

Mid-air Perseus looked at where the arrow had come from and saw only the head and shoulders of his uncle which were slowly dissolving in thin air, a bow next to him. Perseus smiled as he knew his uncle had shot that arrow before he faded away. Although Perseus didn't know how he could've survived for so long, but he didn't care.

The force of Perseus's kick and, mostly, of the arrow pushed Typhon a few yards away where he stumbled over a group of rocks and tumbled backwards into a giant mountain. The mountain crumbled on top of him as he fell a little through the mountain and was buried underneath giant stones, which he couldn't escape out of.

Perseus, who was in the air seconds ago, was now also falling towards the mountain and fell against a couple of stones who crumbled on top of him and he was from waist down buried underneath stones.

Perseus pushed some rocks away with his working arm and tried to stand up but felt to his knee as one of his legs also gave up on working. He looked up and saw that Typhon was knocked out underneath the mountain and wasn't coming out any time soon. He smiled, although painfully, and fell onto his back as his body wasn't full of adrenaline anymore and gave up on working. The pain slowly became more and more as he felt all his wounds from his fight with the monsters and with Typhon. He was covered in a mixture from golden ichor with golden dust and dirt and his clothes were tattered.

He looked up into the dark night sky and saw the moon gone, reminding him of his mother's death, which made his heart clench. He felt his life force slowly fading away from him and he slowly closed his eyes. He promised himself when he reformed that he would train and train more so this wouldn't happen again and when the new heir of the moon was chosen, he would find them and fulfill his job.

He would be the Guardian of the Moon. He would be Luna's Guardian.

Perseus' breathing slowly lessened till his chest stopped moving.

Perseus Jackson officially died.

But this wasn't the end for him yet…

A/N: Okay, so this was the first chapter of this story. I know this is maybe a bit fague but I tried to give you an idea of how he would become 'The Guardian of the Moon'. Btw, I'm not gonna lie, I was dying of laughter when I wrote the oath part. It's so cheesy.

I thank you all for reading this chapter and hopefully I will see you in the next chapter as well! Goodbye my lovely readers, till next chapter!

And oh yeah! Before I forget it, I am definitely not English so there may be some spelling or grammar mistakes, sorry for that and please don't get too mad about it!
