AN: This fanfic is canon to my other fanfic, Star Crossed Darkness. Take a look. It might clarify any questions.
Sora breathed in a big deep breath and blew as hard as he could. The candles each flickered out to the applause of Sora friends around him. Sora could hardly believe it, but today was his sixteenth birthday! It had been about seven months since he had taken down Xemnas and Organization XIII, and, truth be told, he was starting to miss the action and hopping from world to world going on adventures.
"Congratulations," Riku said, "Now you're old enough to drive a car around the three roads on the island."
Sora laughed. What was usually a right of passage to boys his age seemed very minor to Sora who had spent the last few years flying around in space and fighting Heartless, Nobodies, and devious Villains. Driving just wasn't that important in the grand scheme of things.
After eating cake and hanging out, Tidus, Selphie, and Wakka left, leaving just Sora, Riku, and Kairi sitting on the paopu tree watching the sunset, just like old times.
"Do you think we'll ever go back?" Sora asked, talking more to himself than anyone else. Riku shrugged.
"I can't see how things will hold up without us for long," Riku joked. Sora laughed and turned to Kairi who was looking very seriously into the sunset. Sora was confused.
"Kairi," Sora inquired, "What's wrong?"
As if awaking from a trance, Kairi suddenly shook her head and turned to Sora and Riku.
"Oh, nothing," Kairi said, obviously feeling uneasy, "I've just got this funny feeling, like something bad is about to happen." The boys looked at her puzzled. She laughed and shook her head.
"Crazy, right?" She said trying to shrug it off. But right at that moment, something flashed in the sky.
Everyone looked up towards it. It was like a shooting star flying down, but it was still twilight. The object grew bigger and bigger as it grew closer, the trio on the edge of their seat trying to figure out what it was.
Sora's hand was twitching, ready to summon the keyblade if it was dangerous. The object landed with a giant splash on the beach one the other side of the island. Sora, Riku, and Kairi ran across the pier and across to the other side of the island to see what it was. When they got up to it, Sora's heart leaped with joy. It was the Gummi ship!
The ship's door opened. and Mickey, Donald, Goofy, and Pluto all jumped out of the ship. Donald and Goofy ran up to Sora and tackled him with a hug.
"Donald! Goofy!" Sora yelled ecstatic.
"Gawrsh, Sora, we sure have missed you," Goofy said smiling.
"Yeah, I've missed having you around. Hanging out with you makes me look so much smarter," Donald teased.
"It's good to see you again, Sora and happy birthday," King Mickey said, "But we're not here on just a formal visit. Something terrible has happened!"
Sora looked at the king trying to look serious.
"What's the matter, your majesty?" Sora asked.
"Traverse Town," Mickey said, "In her quest for a new lair, Maleficent used her dark powers to turn the former safe haven into a city of darkness."
Sora's jaw dropped. How could this have happened?
"But that's not even the main problem," Mickey said gravely, "The real danger is that something destroyed Yen Sid's tower. Yen Sid and the fairies made it out safely but everything else in his world was destroyed"
Sora went into an even greater state of shock. Yen Sid's tower? It wasn't possible! Yen Sid's magic would have protected it.
"However, Yen Sid's world didn't die in vain," Mickey said. He reached into his pocket and pulled out a small bag. "Yen Sid was able to create this spell that would allow a keyblade to seal a world from meeting this sort of end. Mine's already been outfitted with it but we need to do the same to yours."
Sora, Riku, and Kairi all summoned up their blades and King Mickey went to each of them, reached inside the bag, and sprinkled shiny silver powder over each of their keyblades which glowed white in recognition of the magic.
"Now let's get going" Mickey said, "Sora. You, Donald, and Goofy take the Gummi ship and start going to the worlds, protecting them with the keyblade. Riku. You and I will travel using a star shard. Kairi, I want you to stay safe here. Pluto will keep ya safe if anybody shows up. We can't afford to lose one of the Princesses of Heart."
Kairi started to protest, but everyone else began piling to their stations before she could say anything. Within moments, Sora, Donald, and Goofy took off in the Gummi ship, and Riku and the King had disappeared with the star shard.
On the platform of an old tree house, a cloaked man was watching everything transpire.
"Now all the pieces are in place."
