This is an idea that popped into my mind. If you don't like it I'm sorry I wasted your time.

It was a dark rainy day in this world. A four-year old raven haired girl was sitting in front of an abandoned building. Today was her birthday and the day her parents decided to kill themselves to get away from her.
In her hand was a dark black blade, a keyblade. It randomly appeared in her hand when she fled her old house. Then minutes afterwards strange creatures started to attack her.
Two people started walking down the vacant street. One of them was a full-grown man while the other was a boy a few years older than the girl. The two walked past her, but once they got a few feet away from her, the boy turned around and ran back to her.
Then boy crouched down to her height. "What's your name?" he asked.
"Shouldn't you say your name first?" The girl mumbled.
The boy smiled as he helped the younger of them put on his jacket. It was too large for her, but that was good since it covered her up. "My name is Terra," he answered smiling as the girl held on to the sleeve. "Now what's your name?
The girl finally broke into a smile. "My name is. . ."
Then the scene changed. An older version of Terra appeared in what looked like armor. He was kneeling over an older version of the girl. The girl was on her back wearing a black and white version of Terra's armor. It looked like she was disappearing.
"I'm sorry, Dad," the girl choked out, petting the blue monster by her side. "I tried to reason with. I thought he wouldn't hurt me, but I was wrong. Please take care of Twilight for me." The girl stopped talking and then she stopped breathing. She then disappeared into the large heart in the sky.
Terra cried out her name.
"Xion, wake up!" Roxas, number 13 of the organization, yelled. "Saix doesn't like it when you're late."
The nobody known as Xion groaned and sat up from her bed. "Thank you, Roxas," she thanked tiredly.
As she entered and closed her closet Roxas said, "You're welcome, but who's Terra?"
Xion froze. "What do you mean?"
"Before I woke you up you mumbled the name Terra," he answered sitting on her bed. "The name sounds familiar."
Xion walked out of the closet brushing her hair. "Not really," she lied. "I probably said Terra, but meant earth, not a person." Ever since she had those dreams she made sure not to tell anyone about them. She doesn't know why, but something told her not to tell anyone.
As the two walked to the Room of Gathering , Axel stopped them once they were in the doorway. "Just a heads up Saix is not happy."
"Why?" Xion asked while Roxas said, "Of course he's not happy. He doesn't have a heart."
Axel chuckled a little bit but then he got serious. "You've been late for the last month, leaving and returning."
"It's not my fault he gives me missions that take forever!" Xion yelled defensively. "I can barely get back in time for dinner."
"Then maybe you should pick up your pace." Saix stated hatefully. Xion didn't notice he was there.
"Good luck," Roxas whispered as he and Axel left to carry out their mission.
Xion waited impatiently as Saix went to change or add on to her mission. "Should of kept my big mouth shut." She muttered. As she did, she couldn't help but to over hear a conversation going on between Xaldin, Xigbar, and Demyx.
"I was unstoppable on my mission yesterday," Xigbar bragged. "Nobody can beat me!"
Suddenly Xion got a sharp pain in her head. Then she had a vision. Somebody, who probably was Xigbar when he had heart, was on the ground with a keyblade pointed to his face. Xion seen it before in a dream. It belonged to. . .
"Terra," Xion said. The three men turned to her. It almost looked like she was in a trance.
The aura in the room changed drastically. "What did you say, Puppet?" Xigbar questioned threatenly.
Xion stayed silent, still in a trance. Terra was the one who could beat him. Terra was the reason he has the scar and eye patch.
When the sharp shooter turned away from her, Xion yelled. "I said Terra can beat you. After all he is the reason your face is messed up."
Xigbar summoned out his guns and pointed it at Xion's head. "Say that one more time Poppet, I dare you."
Then at that exact moment Saix appeared with Xemnas behind him. "What's going on hear?!" Saix yelled.
"This Poppet thinks she's better than me!"
"That's not true!" She screeched.
"Quiet, 14. I suggest you keep your mouth or else-"
"Saix," Xemnas interrupted him. "That is enough." Then he walked in front of the female member and kneeled to her heigth. "I wanna hear your side of the story, Xiona."
Xion hesitated when he added the 'a' to her name. It sounded like he has said it to her before. "I was waiting for Saix to come back with my new mission when I heard Xigbar say that no one, including yourself, can beat him. Then I reminded him that the guy that made him have that scar on his face defeated him."
Xemnas nodded his head and stood to his full height. He grabbed the papers in Saix hands and handed him to the girl. "Proceed with your mission for today. It won't be extended anymore."
Xion summoned a portal while Xigbar and Saix were arguing in the background. Before she could leave Xemnas then said, "One more thing before you go, Xiona. Please try not to be late for work."
She nodded her head and entered the portal, wondering why Xemnas would call her that familiar name.
Here was the first chapter. There isn't that many of her so this was created!
