First things first, Kingdom Hearts and all of its characters are the property of Square Enix and Buena Vista Games. I will let you know if I make my own characters.

Part 1-The King's Letter

Dear Sora, Riku, and Kairi,

Sorry to bother you guys after what you've just went through, but I have some information about Xehanort that you might want to know. It turns out that this whole mess with the Heartless and Nobodies can be traced back to about ten years ago. Back then, Kingdom Hearts was an actual kingdom that maintained order among all the worlds. There were also numerous Keyblade Masters, and apparently Xehanort was one of the most respected and powerful among them (It also seems he was a lot older than he looked when we met him). However, he and his apprentice disappeared one day. Believing this to be a bad omen of things to come, the king of Kingdom Hearts sent his three apprentices to find him. When they did, they found out that he had been consumed by the powers of darkness, and was planning on spreading his corruption to the world's core, which would cause Kingdom Hearts to become a breeding ground of darkness and would grant him eternal youth. The three warriors attempted to stop him, but unfortunately, Xehanort defeated them and transformed the land into a world of chaos and turmoil. However, his victory came at a cost. Though the dark energy he received from the world made him young again, it also erased all of his memories and sent him into another dimension. Eventually, he ended up in Radiant Garden, where he became Ansem the Wise's apprentice. The rest you already know.

Hope you're all doing well.
Sincerely,
King Mickey.

P.S. - Donald and Goofy say hi.

Sora: Well, that certainly explains a few things.
Riku: I knew Xehanort was bad, but this takes the cake.
Kairi: At least we know he can't cause anymore trouble.

The three friends were resting at their favorite spot on Destiny Islands. They had just finished reading the letter that Kairi had found in a bottle near the shore. They had no idea that it would contain such valuable information about their greatest enemy.

The letter made Sora think. About two weeks had pasted sense he and Riku had defeated Xehanort's Nobody Xemnas, and they thought that the realm of light would be safe. Why now, was it, that the king had decided to tell them about Xehanort's past. Did he think that Xehanort wasn't as gone as they believed, or was there another reason.

Riku: Why do you think the king is telling us about this now?
Sora: Don't know. Maybe he wanted us to know how this all got started.
Kairi: I can't believe this all began just ten years ago.
Riku: To think this all started back when we were little.
Kairi: But if it's all over, why is he telling us.
Sora: Because I don't think it's over yet.

Riku gave Sora a puzzled look. Kairi, however, looked like deer caught in the headlights of a car when he said this.

Kairi: How can you say that? You and Riku defeated Xemnas. The Heartless and Nobodies can't threaten the realm of light anymore.
Riku: Yeah, I really can't see how this isn't over and done with.
Sora: Come on, guys. If this was really over, then why would the king send us this letter, and another thing...

Sora held his hand out in front of him. Riku and Kairi watched as a key-shaped sword appeared in a flash of light.

Sora: If the darkness is really gone, then why do I still have the Keyblade.
Riku: I'll admit, it is strange that you still have access to it.
Kairi: Maybe your right, Sora. Maybe this isn't as over as we think it is.
Sora: I don't know. This is all so confusing.

Sora turned his gaze to the sky in time to see what looked like a giant ball of fire heading straight for them.

Sora: Get down!

The three of them hit the dirt just as the flaming object zoomed over them. They turned just in time to see it crash into the beach.

Riku: What was that?!
Kairi: I don't know!
Sora: Come on, let's go look.
Kairi: Are you crazy? That thing could be dangerous.
Sora: Will you calm down. We've faced worse things than that.
Riku: You know, he does have a point.
Kairi: Oh, all right. But let's stay together.

The three of them carefully moved toward the large object. As they got closer to it, Sora suddenly heard two familiar voices.

Donald: That is the last time I ever let you drive, Goofy!
Goofy: Garsh, sorry Donald. I didn't mean to come in that fast.

A hatch on the side of the object opened and two figures popped out. One was a large duck in blue clothes and a blue cap carrying a long staff. The other was a tall, dog-like...thing wearing a green vest with a matching hat and holding a shield in his hand.

Sora: Donald, Goofy!

The two of them turned to see Sora and his friends running towards them.

Goofy: Hey, guys.
Donald: Good to see you.
Riku: What are you two doing here?
Donald: We came to get you.
Goofy: The king needs to talk to all of you right away.
Kairi: Really? What does he need to tell us?
Goofy: He wouldn't say, but it sounded like it was urgent.
Donald: Come on, let's not stand around yapping all day. We've got to go.
Sora: Okay, okay. Simmer down, Donald.

The group moved back towards the smoldering object, which Sora now realized was actually the Gummi Ship.

Goofy: Will be out of here as soon as we get this thing running again.

As Donald and Goofy went to work repairing the ship, Sora turned back to his friends.

Riku: What do you think the king needs to see us about?
Sora: I don't know, but based on what Goofy just told us, I doubt it's anything good.
