I own Louie.
You were born into it. You were apart of the tribe of demigods. Most were descendants but you were one of the very few that was a first generation. You had a power that no one else did. You would befriend animals and they would help you. But these powers have failed you before. So let's start at that.
Another monster had found you all. Everyone was unprepared. You saw your friends and family in danger and two bears responded to your emotions. You fought them off before you heard a blood curdling scream. You turned and saw your mother sink to the ground with an arrow through her stomach. Your 6 year old body shook with tears. You felt an arm on your shoulders and saw Louie. Louie was a 19 year old young man with messy caramel hair and startling emerald green eyes. Believe it or not he was your best friend. "I know a safer place for you to go. Come on." He started walking off as you waved goodbye dejectedly to everyone. You walked for while before Louie picked you up. "I'm a son of Tyche, you know." He informed you, trying to distract you. "My dad told me. She's the Greek goddess of luck." Your eyes were starting to got droopy. "We should get there by dawn."

You woke up just as the sun started to rise. "We're here." Louie beamed as you rubbed your eyes. You looked and your jaw dropped at all of the extravagant buildings. "I know, it's amazing. You just nodded. "You should come meet Chiron." Louie put you down and guided you to another building. "Chiron? You up?" Louie called and you heard a reply. "This is (Y/N)." He pushed you forward. "Do you remember what I told you? That I'd only bring her if..." He trailed off and Chiron grew a knowing look. "Her father is Poseidon." Louie stated and Chiron's expression changed. "Are you sure?" He asked. "Positive." Louie placed you on the coach and you fell asleep.
4 years later
Chiron was like a father to you. Louie was an adult now but still came a visited every now and then. "I wanna leave." You told Chiron walking into the big house as Chiron and Mr. D played some random card game. "Sorry?" Chiron said. "I said I want to leave." You repeated. "Why?" He asked looking at you. "I don't know. I just feel... trapped." You said waving your hands around. "Well, it's probably not the best idea but if it's what you really want, I guess you can go." You smiled. "I'll always come back if you need me, I promise, but I'm a lone wolf." Chiron nodded.
You occasionally came to talk to Chiron. Every time you did he would talk about Percy Jackson but you always came when he was gone.
You rode towards the Empire State Building on a horse with a few more behind you. You saw Chiron give a small smile. "I kept my promise." You said. You saw a boy standing next to Chiron and you immediately knew who it was. "So you're the famous Percy Jackson?" You walked over to him. "I'm (Y/N), what do you need me to do?" You asked, climbing back on your horse. "They won't need it but you could give the Demeter cabin some extra hands. You rode away. Every time there was a battle you were there with some kind of animal. You and Percy never realized you were related because you didn't see him often. You came back to visit Chiron. "Louie!" You crushed the 27 year old in a hug. "How've you been, old friend?" You smiled. "I'm not that old." He protested. "So tell me, what animal aided you entrance today?" Louie asked. "Birds."
You always came back when there was a battle and you occasionally brought new campers. One day you got an Iris message. "Hey Will. To what do I owe the pleasure?" You asked. "We need you." He stated. "Excuse me?"
"We have a battle approaching and we all want you to stay." He informed you. "I'll think about it." You started the journey back to camp.
Demigods were losing when a young Athena girl looked to Chiron. "Why aren't you worried?" She asked. "Because I know help is on the way." A howl echoed through the valley. "Chiron! I have a pack!" He heard a familiar voice as everyone turned to you. "ATTACK!" A blur of fur flashed as monsters fell to the jaws of wolves. The battle ended as someone tapped you on the shoulder. "Hello, I've heard about you." You shook his hand. "Nice to meet you, but I'm sorry to say that I haven't heard of you. Could I get your name?" You replied. "Leo. Leo Valdez." He told you. "Well nice to meet you Leo Leo Valdez, I'd talk more but I have to talk to Chiron." Leo blushed as you ran off. "Chiron!" You ran up to him. "I'm gonna stay." You grinned. "And may I ask why?" You grinned some more. "This place is a part of my past that I'd like to revisit."
