I finished writing the 2nd chapter. I hope it's enough entertainment for you.
The story is only in it's beginning stages, so it'll get better as it continues.
This is kinda how I can see the game's plot starting off. This story begins
right from the ending of KH3D. This chapter is longer than my first.
I am expecting them to get longer as it progresses. Enjoy Chapter 2.

I started adding music to listen to while you read from KH OSTs, an optional feature.

Happy New Year! :)

Chapter 2. A Decision to Make

~Magical Mystery plays (KH II OST)~

Now that Yen Sid had finished explaining the situation to Kairi, she had to make her decision. She had been given the opportunity to be shown how to fight with her keyblade like a professional. For her to stand a chance against the Heartless threat she would first need some practicing and be taught the proper ways to use her keyblade. Master Yen Sid offered his assistance in training her personally. Though he hadn't used a keyblade himself for many years he would still try to help her as much as he was able to.
Kairi was more than honored to join her friends in protecting the worlds, but would she really be able to learn the ways of the keyblade in such a short time? She knew it wouldn't be long before the worlds were envaded by the Heartless again, and the Organization would begin their villianous schemes.

Kairi had only just received her keyblade less than a year ago, she hardly had any experience with it. But she knew that the King and Riku were in need of every keyblade wielder they could find, which was why she was here. The way she saw the situation, it looked like she didn't really have any other choice. She needed to learn how to properly use her keyblade so she would be able to defend herself if she was ever in danger. Kairi finally looked up from being deep in her own thoughts, and she looked at Master Yen Sid to give him her answer.

"I've made my decision." Kairi announced. "I'd like to learn how to use my keyblade, and help protect the worlds from darkness. But do you really believe it's possible for me to ever be as good with it as Sora and Riku are?"

Master Yen Sid rubbed his long gray beard and gave a slight chuckle. "I'd expect no less from you, but I am certainly not going to give you that much of a hard time. You will grow with your keyblade over time, just as Sora and Riku have on their adventures. Then in time, perhaps you will take a Mark of Mastery Exam of your very own to earn the name Keyblade Master. But we have plenty of time to consider such a notion." Yen Sid finished saying.

"I'll do my best, Master Yen Sid." Kairi giggled.

Riku walked over to Kairi smiling. "I'm sure you'll do great, Kairi." Riku told his childhood friend. "Wait until Sora hears about you training with a keyblade. I can almost see the expression on his face." Riku grinned.

Kairi smiled happily at the mention of Sora's name. "I hope he gets back soon!" Kairi admitted. "I can't wait to tell him!"

~Magical Mystery ends~

Riku was silent for a moment as he stood thinking to himself. "What could you still be doing Sora?"

Mickey looked up at his Master. "We still need to gather seven keyblade wielders for our guardians of light. But it looks like we're still missing a half of the number of our friends. While the thirteen darknesses are already up to twelve members. We're still so much behind." Mickey pointed out.

Yen Sid sat in his chair with his arms folded, his eyes were closed as he concentrated.

"Master yen Sid?" Mickey called to him, but the wizard made no comment.

Everyone stayed quiet for a second, not wishing to disturb the old wizard in his thoughts.
Finally, Yen Sid opened his eyes and looked directly at the King.

"Mickey, I'm afraid I sense a change in the balance of light and dark. Something is amiss. Master Xehanort must be up to something this very minute. I fear the seven lights could be in danger."

Everyone gasped!

"Master! What should we do?" Mickey asked starting to get worried.

"I think this situation calls for Sora's attention. We need to locate Sora to inform him that the worlds are in need of our protection." Yen Sid prompted.

Donald and Goofy looked at him troubled.

"But Master. We don't know where Sora is! How will we find him?" Goofy questioned the wizard.

"Didn't we see him open a portal to the Sleeping Realm before he left?" Donald added.

Yen Sid nodded at the two. "You did indeed see him journey back into the Sleeping Worlds, but I do not sense his presence there now. Which could only mean he has returned to the Realm of Light. My calculations might be wrong, but I think I sense him somewhere in the lanes between light and dark. Determining the exact location of one's current destination isn't always easy to get correct. But what I can tell you is that you won't find him in the Sleeping Realm."

Riku listened closely, interested in finding his friend. "So you're saying Sora is back, just in a different world? Hmm? I wonder why he didn't meet us back here as soon as he returned." Riku said, confused. Yen Sid was silent as he stroked his beard.

"King Mickey, if you'd like, Donald and I could go find Sora and bring him back here for Master Yen Sid." Goofy volunteered.

Mickey smiled at his friends. "Well, that sounds like a good idea to me!" Mickey replied. "Riku? What do you think?"

Riku could see how much getting to look for Sora meant to Donald and Goofy. He couldn't help noticing them worrying over their friend's safety. He had intended to take the responsibility of going after Sora himself, but it appeared they had beaten him to it. "I guess, it looks like those two have got it covered. I'll stay here and go over the plan with you and Master Yen Sid." Riku answered Mickey.

"That sounds good to me!" The King agreed. "You fellas go find Sora then. We'll wait for you here."

Donald and Goofy were excited to get to be the ones to look for their friend. They prepared to leave at once.

"Where should we look first, Master Yen Sid?" Donald asked with full respect.

"You two might try the place where your last journey began, first." Yen Sid suggested.

Donald and Goofy both nodded and then bowed before leaving Yen Sid's chamber.

"Good luck!" Kairi bid them happily.

Riku, Kairi and King Mickey watched the gummi ship fly away outside from the star shaped window in the tower.

Until the next chapter, stay tuned. Can you guess which world they will visit first while looking for Sora?

Hint: The world where their last journey began.
