The door to Begining

A/N: This is my first time writing a fanfiction like this. I hope you like it.

"In the world where fantasy blends in with reality, the future remains uncertain."

"Every story has a beginning but mine hasn't even begun yet."

(10 years before the main story)

"A peaceful place isn't it?"

The salty smell of the ocean breeze wafted through the air as the woman took her first step on the golden sand. Her short blue hair was dancing lightly within its soft brush. Sapphire blue eyes were watching the blue ocean lay in from of them. She seemed to be deep in thought, but it would seem like sadness had filled her vision. The woman placed her hand on the young boy shoulder, causing him to look at her. He was pretty young, almost 4 in age with his light brown hair messy pointed to all side. The young boy looked more like his father, especially with that hair color. He wore what looks like a white T-shirt with blue lining and red shorts with a maroon pocket on each leg, as well as brown sandals with yellow straps.

"I'm sure you'll be safe here." The woman, Aqua, spoke again. This time sadness was clearly visible within her voice. The boy looked up at her, his big blue eyes turned to her curiously. He titled his head to side, completely obvious of what caused her to be so upset.

"Mom?" He called.

"I'm sorry Sora, but this is the only way to keep you safe." She wiped away her tears silently, while trying to contain the ones had yet to fall. It was just too much. No farewell had ever considered to be happy, and this one would be any different. Aqua bit down her lips as she lightly ruffled his hair. This wasn't going be easy but whatever shall she do?

"Mom …" He tugged her white lance to catch her attention. "Why are you crying?"

"Nothing's Sora. I'm alright." She quickly wiped away the tears, trying to hide away her pain. He wouldn't understand. Sora was just a little boy after all. There was no need to make him face any pain. His time would come soon enough. He would understand when he is ready, there was no need to rush anything. Yet, what matter at that moment was his safety, as she could no longer be by his side to protect him.

"Mom, please don't be sad. Everyone will be alright. They're really strong." He spoke with a bright smile. His words caused her to force out a smile even if it was just a faint one. The corner of her lips moved into a small smile while she placed her hand on his head. If only it was as simple as he said it was. But perhaps, somethings were best left unspoken.

If anyone asked her how did it come to this then she just couldn't explain the reason why. Everything was perfect few months ago. But then wars started out. As a Keyblade master, a title that she had recently earned, she had no choice but to take part in to deal with the threat. Terra and Ven were no different. They too, fought alongside with her but no one knows what have happened to the both of them.

'And my end is coming as well, I can feel it.'

"Yes, I believe they are too." She said, yet the words only came out as whisper. She wanted to believe it is all true, but she found it hard just to do that. Terra, she had to find him to be sure of that herself. Sora needed both his parents and she had to keep him away from harm. So as much as it broke her heart, she still had no choice but to send him here, to a peaceful little place known as Destiny Island, the very same world that boy lived in, the very same one Terra trusted in passing along the power of the Keyblade.

"Sora." She spoke again. "I have to leave again, as much as I don't want to leave you, I have to find your father and stop the darkness from spreading. You understand, don't you?"

"You're gonna leave me again?"

"I'm sorry, but I can't take you with me." She lowered herself so that their eyes would meet "You'll be safe here. You'll have wonderful friends, I'm sure. I even ask 'his' parents to look after you for me. You'll be alright, trust me. We'll see each other again."

"You'll come back? Promise?" He held out his pinky. The action caused soft chuckles to escape from her lips as she took his pinky in hers. "I promise."

"I'll miss you mom." Sora let go of her pinky and wrapped his arms around her as much as he could.

"I'll miss you too, little Sory." She hugged him back "Now be a good boy and behave, alright?"

"I'll be good, I promise." He let go of her and smiled.

"Alright, I guess this is good bye. You should able to find this 'friend' here, who will help you when needed." She stood up again and kissed his forehead before straightening her clothes.

"But not farewell." Sora added hopefully.

"But not farewell." Aqua repeated, smiling softly at him and gave him a light push into the direction of the beach, where another present was located, a young boy who seemed to be only older than Sora about an age. Sora looked back at her, only to earn a short nod of encouragement before walked over the boy.

Yet, by the next time he turned around. She was no longer there

It was then when everything began to change. No one can tell what is the outcome of things. But I believe. There will be a bright future where we can all be happy again. Even if everything seems gloomy, even if tomorrow sunlight will never come, it gives us no excuse to drown ourselves in the dark. Miracle can happen but not if you wait for it. I'll fight my battles, until the day when light will reach me once again. Until then, I'll wait … and believe. You'll be the one who will set right again. I believe in you.
