Hello there everyone it's me animediva943 posting yet another new story. I know that usually try to stay away from this fandom because of the fanfics and insane fan girls but I've decided to face my fears and post this story after having it in one of my books for 3 years. So without further ado, here is Sanctuary.

I don't own, Disney, Square Enix, Kingdom hearts or any of its characters. I may be broke but I don't make any money off of writing this story.

Sanctuary

Chapter 1: Darkness in Kairi's Heart?

Sora and Riku Defeated Xemnas, organization XIII's superior. Since then so many things have changed for them and for their friends. To begin with, of all of the Nobodies that they met, some of them got hearts and became human again. Roxas, Axel, And Namine were the lucky ones who ended up getting their hearts back. In addition, Roxas and Axel were the only two members of Organization XIII to get their hearts; mostly because they earned them. All of the other's were doomed to remain into the darkness for what seemed like an eternity. However, before those three got their hearts back, some very serious events happened right after Sora, Riku and Kairi read the letter from King Mickey. Sora, Riku, Donald and Goofy remembered the whole ordeal like it was yesterday.

Another interesting fact was that they were on their way to radiant garden to find Merlin for an antidote for something.

Flashback-1 week ago

"Sora, Riku!" Kairi called from across destiny islands. She was in sheer joy to see that her best friends have finally returned after a long and hard fight with Xemnas. She was holding an envelope and then showed it to the two boys.

"I found this letter." She said. Then they all looked at the note together.

"From the king?" Sora asked as they read it. What they read was very surprising but at the same time a very pleasant turns of events.

Today is the anniversary of my coronation and I would like all of you attend the coronation day party here in Disney castle. I'll see you real soon.

King mickey.

p.s you may see some old friends you thought were long gone. The party starts at 8:00.

"A coronation day Party, Huh?" Sora said. He thought that it would be a nice change from fighting villains like Xeanort and Organization XII. Finally the trio would have some time to relax and see their old friends again. It had after all been some time since they last saw Donald and goofy. They all got some of their best clothes and were preparing to go to one of the few parties that they had ever been invited to. But one mystery remained. What did King Mickey mean when he said they would see some old friends that they thought were long gone? They would find out soon enough.

LATER THAT NIGHT…

The trio went to Disney castle and was reunited with quite a few old friends. From Donald and goofy to samba to Muushu, Everyone that Sora met on his adventures was at the king's coronation day party. The biggest surprise came when they saw that Roxas, Namine and Axel were at the party.

"What? Axel, Namine, how did you…when did you…?" Sora was pretty much speechless seeing the Axel, Namine and Roxas in the flesh. It looked like now he knew what the king meant. Riku and Kairi were also shocked to see that some of the nobodies now existed. It wasn't long before king Mickey came and explained everything to them.

"I know that some of you are very surprised to see them now but let me tell you about everything that happened. After Xemnas faded into the darkness, there was a disturbance in the balance between the light and the darkness. Just before the door to kingdom hearts closed, three hearts managed to get past it. Those three hearts managed to find Axel, Roxas and Namine. That is how they became human." King Mickey explained.

They seemed to understand what was going on now. They all talked to Axel and sora and Kairi's respective Nobodies.

After a significant amount of time, Sora,Roxas,Axel, Donald and goofy seemed to all be a lot closer to each other. Kairi and Namine became close as well and the most surprising connection of all was the connection between Namine and Riku. Everyone was very stunned to see it, especially Sora and Roxas. For the remainder of the celebration Riku was taunted by Donald and Goofy about possibly liking Namine, Riku of course tried to ignore them but they just teased more about his supposed crush.

"Come on Riku," Donald said. You know you like her." Donald was gently nudging at the silver haired boy's shoulders. Riku then walked away and went to see how the others were doing.

Meanwhile, at a nearby punchbowl, Kairi was getting punch from an ominous looking figure at the table. He appeared to be a normal looking teenager like them. But there was something about his lack of interaction with the other guests that stood out, and not in a normal way. She drank some of the punch and then poured herself some more. Then she went back to the party but something didn't seem right. Suddenly the red haired girl felt strange.

"Ugh, my head." She complained. "It hurts so much." Then she started to feel dizzy as well. Then it looked like drinking that punch may have made her ill.

"Kairi, what's wrong?" Riku asked looking concerned.

"I don't know, I drank some punch but then I started to get these strange headaches and I'm dizzy." Kairi said.

"I guess we should take you home then." RIku said. Then he took his friend in his arms and went to find Sora. He found Sora getting ready to leave the party. How convenient.

"Huh, Riku?" Sora said."What's going on." He then saw an ailing Kairi. He knew what had to be done.

"Let's go home then."Sora said. Then as they headed home they nothing that something wasn't right with Kairi and it wasn't just that she was sick. She pulled away from Riku and then out of nowhere, everything at the party fell apart slowly but surely. Plates, forks and glass were flying all over the castle. The guests were forced to flee due to the invasion of what appeared to be hundreds of heartless and nobodies.

"Looks like my pets want to play." Kairi said unexpectedly.

"Pets? Kairi what are you-" before sora could finish his thought he finally realized what happened to Kairi. Not only did she get sick. But it looked like she did have darkness in her heart after all. Perhaps it was dormant until now.

Then they took a look at Kairi who didn't appear so sick this time. Then a helicopter forcefully pulls the roof off of the castle then a beam falls to the ground and stole the gravity right from King Mickey's feet.

When Donald and Goofy tried to help him, they were pulled from the ground as well and then led into the Chopper. Then Kairi Jumped into the beam and went on the helicopter. Leaving Sora and the other's alone to deal with the heartless.

They fought and fought and the heartless were taken down dozen by dozen. When it was all over, there were no more heartless and the nobodies, being cowards were forced to retreat. Exhausted from the fight. They all had to wonder one thing. What happened to Kairi?

BACK AT DESTINY Islands

"I don't understand." Sora ranted. "I never thought that Kairi would end up betraying us. Something isn't right."

"Kairi didn't betray you." Axel confirmed. Sora was a bit confused at first.

"I think I know Kairi when I see her." He remarked. Then he let Axel explain his theory on Kairi's sudden mood swing.

"That punch that that guy was serving was spiked with something." He began to explain then he showed the others a beaker filled with some pink powder.

"It's a heart stealing potion. One sip and you turn into a heartless. The creator of this potion is called Natalus. Got it memorized?"

"Well, How are we supposed to find this Natalus." Roxas asked.

"The first thing you should worry about is finding an antidote for your friend." Axel suggested.

Sora then knew who to go to for an antidote.

"Then we should go find Merlin." He added.

end flashback.

Now sora and his friend were on they're way to radiant garden. Hopefully they could find an antidote and help Kairi before it was too late.
