Keys of Light (A KH X SW Crossover)

Prologue: Rescue and Gathering

The massive city stretched farther than he thought possible. He hadn't seen anything like this in his travels. The closest he could think would have been San Fransokyo, but this city put that world to shame. He should have been used to its size, though. He'd been there for almost a week. In that span of time, he'd been attacked by giant robots and even people with strange weapons and abilities that could rival the keyblade. Now he was at a large crosswalk section near a building with the number 104 on it.

This is it, he thought, it has to be.

"Yozora!" He heard above him.

He summoned his keyblade just in time. He blocked above him and saw a semi-relieving sight. His brown spiky hair, the piercing blue eyes, the keyblade... it was Sora. His face had dirt on it and he wore a scowl that could run chills down any other person, but not him.

"Sora," he shouted back, "I'm not whoever Yozora is! It's me! It's Riku!"

Sora's face softened as he landed on his feet and he noticed that the eyes were the same color, the weapon was a keyblade, and...

"Riku..." he responded, tears forming in his eyes, "it's you. You're here. Why?"

"We've been looking for you, Sora. All of us. Mickey, Donald, Goofy, Terra, Aqua, Ventus, Roxas, Axel, Xion, me... and Kairi."

Sora fell to his knees, crying. Riku found him.

"Come on, Sora. Let's go home."

Riku created a portal back to the real world and, after putting Sora's arm across his shoulders, walked through it with him. They emerged into The Final World. Riku looked behind him and saw the star who opened the portal. Sora looked with him and saw the star.

"Welcome back, Sora," she said.

"Thank you," Riku said, "for allowing me to go to your world to save him."

She chuckled. A flash of magic appeared in front of them. When it cleared, they saw the Fairy Godmother.

"Well done, Riku," she said, "I am so relieved you managed to find him." She turned to Sora, "And how are you feeling, dear?"

"Tired," Sora said, "like I could sleep for a decade and still not be better."

"I am sorry to hear that. But rest assured that you will get the chance to rest soon. I'll let Yen Sid know that you were found."

She about left when another thought came to her.

"Why don't you come with me, dears?"

They disappeared in a flash of magic. They soon appeared in Yen Sid's throne room. He looked at all three and smiled.

"Ah. I believe congratulations and thanking are in order," he said, "Riku, you have brought Sora back to us. I thank you. And Sora, you brought back Kairi and lived in a world we know nothing of. I am glad that you are back."

"I feel like there's a 'but' coming," Sora said, "so what is it?"

"You are correct. Another portal to a mysterious reality has opened. I task you both with exploring it."

Sora and Riku exchanged a glance that held worry.

"With all due respect master," Riku said, "I was in Quadratum for only a week and I was almost overwhelmed more times than I could count."

"And I could barely sleep from fear of attack," Sora said, "If we're going to another unreality, or something, I don't think we can do it alone. Could the King, Donald, and Goofy help us?"

"I have tasked Mickey with learning more about this 'Quadratum' in Scala Ad Calum, and Donald and Goofy are accompanying him."

"Even then, Sora," Riku said, "I don't think five of us would even be enough."
