Chapter 1: Daughter of Acnologia

~PAST~

The era of dragons were dangerous as a lot of dragons destroyed a lot of humans. But some dragons decided to save humans and raise them as one of there own. Acnologia was a destroyer of dragons and humans. He only lived to kill. His older brother Igneel wanted to save humans. Igneel saw a little boy and he decided to adopt him and protect him from other dragons. He named him Natsu Dragneel, but eventually he was going to make Natsu a peace maker between dragons and humans. Not far from Igneel and Natsu, there was a woman named Layla. She gave birth to a baby girl and the father left them. She went to Igneel as she was being attacked by Acnologia.

"Igneel," said Layla.

"LAYLA," said Igneel as he came to her rescue.

"DARK DRAGON ROAR," roared Acnologia as he fired at Layla.

"BROTHER ENOUGH," said Igneel as Layla hid under him. "FIRE DRAGON SHIELD!" Layla took cover as she screamed. Igneel held him off and he roared for his friends such as Grandine, and Metalicana. They came to his call and attacked Acnologia.

"STOP THIS NOW," said Grandine. "SKY DRAGON ROAR!"

"ALL MUST DIE BY MY FIRE," said Acnologia in anger. Igneel looked at Layla and he smiled. He grabbed her and flew her to his secret cave and put her with was still little and he was sleeping.

"Stay here," said Igneel. "You'll be safe and we will hold off Acnologia. Some of us dragons want to make peace with humans."

"I agree," said Layla as she held her baby in her arms. Igneel went back off to fight. Back in the air, Grandine and Metalicana were down and Igneel got really furious.

"NO GRANDINE! METALICANA! YOU WILL PAY FOR THIS BROTHER," roared Igneel.

"Don't be so pathetic," said Acnologia. The furious dragons kept fighting Acnologia, and they made him retreat, but all of them were wounded. They coughed up blood.

"I WILL COME BACK FOR MY REVENGE," said Acnologia as he retreated for the moment. Igneel looked at his friends.

"Metalicana, Grandine are you ok," asked Igneel as he went down.

"We will be fine," said Metalicana.

"I don't want this war to continue," said Grandine. "What do we do?"

"I am planning to to raise humans to stop the war between human and dragons," said Igneel. "I am raising my son. I am protecting a mother and her child."

"But putting human at risks," said Grandine, "Will only get them killed for our mistake on humanity."

"But we will fight with good humans," said Igneel. "We will make them become dragon slayers. They will slay the evil dragons and save our kind from fear. You two should raise kids as well."

"Don't be ridiculous," said Metalicana. "I can't raise a child!"

"Don't be a fool," said Grandine. "If what Igneel says is possible then we can raise the era of dragon slayers to bring peace to our world." Metalicana sighed.

"Fine," he said.

"We will meet again Igneel," said Grandine. "But we must recover from Acnologia's destruction."

"Agreed," said Igneel. Metalicana and Grandine flew off and Igneel went to the cave where Layla, her child, and Natsu were. He laid down injured. Layla ran to him.

"IGNEEL," said Layla. "You're hurt!"

"I'll be fine Layla," he said. "You should be safe now. I'm going to raise Natsu to bring peace to our world. I'll bring you home ok?" Layla nodded as she held her child and Igneel brought her home. As the days went on and things seem peaceful, Acnologia grew in more hatred of his brother. Soon he decided to make his attack on Layla and her daughter.

~END OF PAST TO THE PRESENT~

As the dark sky arose, Acnologia decided to make his move. He went to Layla's house and set it on fire. Layla grabbed her daughter and ran out the door. She saw the dragon and screamed.

"NO," cried Layla. The scream woke up Acnologia as Natsu was safe and he flew over.

"Mommy," said her child afraid to move. Acnologia came and grabbed the girl as Layla cried in agony. She was only a few years old when he took her away. Her mother tried to stop him but couldn't as she cried as her girl was taken away from her. Acnologia looked at the human girl in his hand as he went to his cave. Layla cried and Igneel heard her and came to her immediately.

"Dear Layla," he said. "What happened?!"

"That dragon took my daughter," she said. Igneel knew that she was talking about Acnologia. He grit his teeth and growled in anger.

"I will retrieve her," said Igneel. "I will save your daughter." As they were talking, a shadow stabbed Layla in the heart. It wasn't from Acnologia at all as he took the child to his own cave, instead it was a shadow type dragon, but it wasn't Igneel's shadow friend. Igneel went to human form, and caught her in time. Blood came out onto his hands as he couldn't stand it.

"LAYLA," he said as he held her and was on his knees and tears fell from his face. "AAAAHHHH!" Layla looked at him as she was bleeding and touched his face. She smiled at him. She tried to say her last thing.

"Save...my daughter," she said as she gasped for air. "Stop that...monster, and bring peace...Tell my child...I...love her..." Her hand fell to the ground and Igneel looked at her as he growled and looked up as he held Layla in his arms. He knew he had to stop the war of dragons and humans. He buried Layla in a peaceful place.

"I will get your daughter back," he said as tears fell and he went to take care of Natsu. He thought that the shadow that killed Layla was Acnologia. He got angry but he stayed calm. Back with Acnologia and the girl she was only five years old, and he made her lose memory of her mother. She opened her eyes and looked at his nostrils. She screamed, and Acnologia sighed. He went to human form and kneeled to the girl. She was shaking.

"Don't be afraid of me little girl," he said.

"Who are you," the little girl replied in terror. Acnologia smirked as he put his hand out and put it on her head and rubbed it. The girl looked at him.

"I'm Acnologia," he said as he looked at her. "I'm a dragon slayer and that is what you will become. You are mine."

"Oh...What's my name," the little girl asked. Acnologia didn't think that far as he picked her up and held her in his arms. He was thinking of a name as he saw the little girl started to shiver. He wrapped her with his cape and held her close.

"Your name is Lucy Acnologia," said Acnologia with a smirk. "You are my daughter."

"Daughter, of a monster," asked Lucy as she was so terrified to look at his face. Acnologia just chuckled at her.

"No, daughter of a dragon," replied Acnologia a bit annoyed but staying calm as he could. Lucy smiled as he put her down. He went to dragon form, and Lucy slept in his arms since she didn't know her past. Acnologia sighed as he watched her sleep and wondered what happened to him, and he questioned himself. That he wanted to kill for blood, but he didn't want to harm a little girl. He looked at her as she slept and looked out. Soon he fell asleep as well. Lucy woke up in the middle of the night and looked at the moon. She looked at Acnologia and put her hand on his nose. He woke up. He looked at her as he was still sleepy.

"What is it now Lucy," he asked as he opened his eyes.

"Nothing Acnologia," said Lucy as she smiled. "Come to see the moon with me." Acnologia sighed as he yawned really loud and Lucy covered her ears. He did look at the moon and then looked back at Lucy. He sighed.

"Call me dad for short ok Lucy," said Acnologia as he stretched his legs. Lucy smiled as he came over and looked at the moon. He sat down as Lucy sat on his head.

"Beautiful isn't it," asked Lucy.

"Whatever," said Acnologia as he sighed and looked at the moon. Not far was Acnologia's brother Igneel. Igneel kept his son Natsu safe from dangerous dragons. Natsu loved his dad because of his love and compassion. Even though he could be stubborn with Igneel. Natsu woke up in the middle of the night and woke up Igneel. Igneel growled and then tried to go back to sleep. Natsu kept trying to wake up his dragon father.

"Come on Dad," said Natsu annoyed. "Wake up!" Igneel opened his eyes and looked at Natsu.

"Oh fine," said Igneel as he sat up and they looked at the moon together. Soon Igneel smelled something, and it was Acnologia. It was same for Acnologia as he smelled Igneel.

"Dad," said Natsu. "What is it?" Igneel looked at him.

"It's nothing my Natsu," growled Igneel. "But I smell my brother Acnologia. I have a score to settle with him! He will pay for what he did to Layla!"

"Can I come! Please! You promised," said Natsu. Igneel remembered his promise that Natsu could come, and got him on his back and flew off. Acnologia growled as he knew that was Igneel. He looked at Lucy who fallen asleep against him. He nudged her to get up and she woke up.

"What is it daddy," asked Lucy.

"Lucy," he said. "Come with me." Lucy woke up and giggled.

"Ok Daddy," she said. She got on his back, and they flew off, and soon they met.

"IGNEEL," roared Acnologia.

"ACNOLOGIA," said Igneel in anger. "WHY ARE YOU HERE? HERE TO SEEK REVENGE AFTER ME?!"

"Dad," said Natsu. "Who's that?" Igneel forgot that he had Natsu on him.

"That's my brother Acnologia," said Igneel. Soon Lucy appeared on Acnologia's head. She sat down.

"Dad, who's that," pointed little Lucy.

"Not now Lucy," said Acnologia as he put her out down. Igneel did the same with Natsu. They went to battle again. Lucy and Natsu looked at each other.

"YOU KIDNAPPED LAYLA'S DAUGHTER," said Igneel.

"No, I took her in," said Acnologia. "I could have eaten her, but I wanted to raise her."

"YOU KILLED LAYLA," said Igneel in anger. "HOW COULD YOU?"

"I didn't," said Acnologia as their flames collied.

"DARK DRAGON ROAR," roared Acnologia.

"FIRE DRAGON ROAR," roared Igneel. There were giant explosions in the sky, and Lucy screamed as she covered her ears. She had bits of her past as she cried. Natsu didn't know who Lucy was but he couldn't stand her crying. Natsu ran over to her, but Lucy backed away in fear. She didn't know if she could trust her father's enemy's son.

"I'm not here to hurt you," said young Natsu. "Our dads have a history. I can get you somewhere safe." As they were starting to know each other, Acnologia got angry with Natsu.

"STAY AWAY FROM MY DAUGHTER," commanded Acnologia as he fired his flames at Natsu. Igneel countered that attack.

"YOU'RE DAUGHTER," asked Natsu. Acnologia growled as he came down to get Lucy, but Igneel stopped him.

"DAD," screamed Lucy. "NO!"

"Dad, stop it," said Natsu. Soon Lucy dug her head into Natsu's chest. She gripped his scarf. Acnologia growled at Igneel.

"How dare your son touch my daughter," roared Acnologia.

"HEY YOU OVERGROWN LIZARD," said young Natsu. "YOU ALMOST KILLED YOUR DAUGHTER! ARE YOU NUTS?"

"BE QUIET NATSU," said Igneel in anger. Natsu stayed quiet. He looked at Lucy as she was terrified. He took her to a cave as the dads were sorting it out. Lucy still had her face dug into his chest. He held her close. Lucy started to cry, and Natsu kept her safe.

"Don't worry," said Natsu. "I won't let anyone hurt you!" Lucy looked at him and blushed as she saw Acnologia keep fighting Igneel, and she cried for him to stop. Natsu saw the care in Lucy's eyes for Acnologia. She looked at the fight as she stepped outside.

"DADDY," cried Lucy. "PLEASE STOP!" Acnologia saw this, and he stopped and landed. He didn't want to scare his daughter. Lucy ran to him and hugged his nose.

"Lucy," said Acnologia. "I'm sorry...Let's go at once." Lucy couldn't argue as she got on his head and they flew off. Natsu came out and went to Igneel's side.

"Goodbye Natsu," said Lucy.

"Goodbye Lucy," said Natsu as he waved goodbye.

"Don't talk to that boy my daughter," demanded Acnologia. Lucy said nothing as she put her head down and they took off.

"Igneel," said Natsu. "Who is Lucy?"

"Lucy was stolen by Acnologia," said Igneel. "He took her from her mother. We will help her and stop my brother!" Natsu nodded as he looked out to the distance. Acnologia went to human form and looked at Lucy.

"I don't want you to see that boy again," said Acnologia. He saw her wound on her arm and saw how afraid she was. He walked to her and picked her up. He licked her blood. It stung a bit and Lucy looked at him as she couldn't stop thinking about Natsu. But she loved Acnologia as family.

"Daddy," said Lucy. "What are you doing?"

"Healing you my daughter," said Acnologia. He wrapped her arm. Lucy nodded as she fell asleep. But she missed Natsu as she slept against Acnologia.

"Daddy...why can't I meet Natsu," asked Lucy.

"Because he is my enemy," said Acnologia. Lucy said nothing as she worried as she slept. Even Natsu worried as he slept with Igneel.

"Dad," said Natsu. "Will I see her again?"

"Yes you will one day and we will free her," said Igneel. "Something is strange about my brother that he took a little girl in. How interesting. Time for bed Natsu." Natsu nodded as they went inside. The brothers kept them separated for years as they knew they were going to meet again and that this wasn't over. Lucy wanted to see Natsu again, but she knew that it was going to be years. Acnologia decided that Lucy would inherit his power as a dragon slayer and a celestial wizard. Igneel looked at Natsu as he slept.

"Hopefully you can bring peace to my brother," thought Igneel. "Grandine...Metalicana, we must make dragon slayers bring peace to this world!"

Will Natsu and Lucy meet again? Or will the dragons keep them apart? Can they bring peace to the war of Dragons and Humans?
