It was a regular day in Destiny Islands, Sora battling Riku, Xion and Namine were playing Beach volleyball, Roxas was surfing, and...Kairi was running up to Sora with a letter in her hands.

"Hey, Sora!" Kairi called out to them, Sora and Riku turned their heads. "What's up?" Sora asked, putting his Ultima away. "A letter from King Mickey." Kairi replied, handing the letter to him. "We should probably get the others." Riku said. "Good idea." Kairi nodded in agreement.

"Sora, there's something that's going on in another world, come to Disney Castle so I can give you the details. – Mickey."

"What world could it be?" Roxas wondered, surfboard in his hands. "I dunno, but it sounds interesting." Riku thought. "Maybe it's a world we never been too." Sora thought, as Kairi nodded in agreement.

"Wait a minute." Namine thought out loud and looked at Xion and Roxas. "Can't you use a Corridor of Darkness to take us to Disney Castle?" "Are you kidding?" Xion asked. "We can't do that anymore, I dunno why." "Probably because we have hearts now." Roxas said.

Then, a familiar ship landed in front of the six. It was the Gummi Ship. "Well, never mind about the corridors." Riku said, looking at Donald who is waving at them.

A few hours later, the Gummi Ship landed in front of the castle doors as they all walked up to the door that leads to the Throne Room. "Whoa...that's a huge door." Xion looked up in awe. "Does a giant live here?" Roxas wondered, as Sora chuckled. "Of course not." Donald knocked on the door a couple times, revealing a smaller door. "Here ya go, the king awaits." Donald told them as they walked through the door. "Geez, if there was a smaller door, then what's the point of the huge gigantic door?" Xion asked. "I dunno, it makes me wonder too." Sora shrugged.

"Ah, you guys made it." Mickey smiled. "Come, let's go in the library." They all nodded and went to the library.

"So what world is in trouble? Pride Lands, Traverse Town, Twiligt Town, Halloween Town..." Sora attempted to continue but Mickey silenced him. "None of those." Mickey smiled. "It's a new world that you never been too." "Ooooh."

"You see, the Heartless have spread like wildfire in the world a few hours ago, they even took a princesses heart." "A Princess?" Sora asked, looking at Kairi. "Not a Princess of Heart." Mickey told him. "A princess that watches over their people and the land." "Yeah Sora." Riku gently nudged Sora. "Shut up..." Sora mumbled, causing Mickey to laugh.

"So what's this world called?" Xion asked. "This world is known as Hyrule, but there are lots of Heartless around." "Nobodies?" Roxas asked. "Nope." "Oh good, at least we won't have to deal with those guys." Roxas sighed with relief. "Wait, quick question, where's Axel?" Mickey asked. "You mean Lea?" Xion asked. "He's back at Radiant Garden." "Ah."

"By the way, for some strange reason there is no keyhole in that world, but the Heartless are already there." "If there's Heartless, someone obviously called them there." Riku muttered. "It has to be Maleficent." "It could be, but I'm not too sure." Mickey scratched his chin in thought. "You think you six are up for it?" "Yeah, we faced Heartless before, you think going to another world is going to stop us?" Sora grinned, causing Namine to giggle.

The six walked to the Gummi Ship and got in. "Sora, you sure you can control this thing?" Riku asked. "Last time I checked, you crashed right into Deep Jungle." "That's because Donald distracted me." "Riiiiight, because you thought Kairi was in that world." Riku replied back with a smirk. "Oh shut up!" Sora shot back, as the girls were giggling, and Roxas was just rolling his eyes.

"Alright." Sora turned his head to the rest. "Ready?" They all nodded. "Let's go!" Sora turned the Gummi Ship on and flew to the world known as Hyrule.
