Sora, Riku, and Kairi, it is time to go to new worlds. Get ready, for this may be our biggest adventure yet. Donald and Goofy are on their way to pick you guys up. I won't be accompanying you yet, for I have some business to attend to.

"It's signed King Mickey. So, our work's not done," Sora said.

"Apparently not," Riku replied. "Figures. Our work may never be done. There are many worlds out there, after all."

"Wonder when Donald and Goofy will get here?" Kairi asked.

"Who knows? Travel doesn't happen instantaneously, though they may be here any day now. It must have taken the bottle a while to get here," Riku said.

"Wonder what new worlds we'll see?" Sora said, as energetic as ever.

A couple of days later, Donald and Goofy came in the gummi ship. They found Sora, Riku and Kairi all waiting at the beach on their island.

"You're here!" Sora yelled as he went to greet his friends.

"So, did the King tell you more about what was up than what his note said?" Riku asked.

"Um, not really. Just that we need to make contact with new worlds. Worlds that might have been around far longer than even Castle Disney, but just haven't been connected yet." Goofy said.

"Well, we can do that, can't we?" Sora said.

"Of course!" Donald said. "The King also said that the Heartless may be a problem in the new worlds too. And Nobodies, as well."

"We can take care of those," Sora said.

"After beating Xemnas, I should hope we could," Riku said.

And so, the five set off on their new adventure. They boarded the gummi ship, which had been expanded to accommodate five, and took off. The first world they came to was preparing for all out war, and they would have gone on except that they noticed that there were Heartless vessels circling the world. So they landed.

Eragon and his small band walked in the night, heading towards Dras-Leona and Helgrind. He stretched his mind to its furthest reach, but did not find anything that was unusual. Certainly not the Lethrblaka or the Ra'zac.

Then, strange creatures brushed against his consciousness. He recoiled as soon as he found their intent. And that was to take hearts.

The creatures attacked swiftly, and before Eragon could warn his band, they were under attack. From the shadows on the ground rose many of the creatures. Many more appeared all around them. Eragon drew his sword, a plain weapon, and struck at one. It did no good.

For some odd reason, only half of the weapons that were used against the creatures did any good. Roran's hammer smashed into a creature, and it disappeared. Eragon then decided that maybe magic would fare better. Uttering a quick spell, a fireball burst forth from his palm and quickly dispatched three of the creatures.

Saphira incinerated many with her fiery breath, but more kept coming. Some were even stronger, and of different shape, than the first ones.

Sora saw the battle before anyone else did. If he stood and counted, he might have counted close to a hundred. All were swarming around the small group of men and a dragon.

"They need our help! C'mon!" Sora yelled as he ran ahead, Keyblade in hand.

"That's quite a few Heartless. He's gonna need our help," Riku said, chasing after him, his own Keyblade in hand.

"Let's go! More Heartless just keep appearing!" Donald yelled and the rest followed. As soon as he got in range, he cast Thunder spells on the Heartless.

Sora quickly dispatched five Heartless, using the momentum of his Keyblade to perform combos. Riku did the same. More Heartless replaced them.

"They just keep coming!" Sora yelled.

"You're not gonna give up, are you?" Riku asked.

"No way!" Sora replied.

Sora noticed the flying Heartless attacking the dragon. He jumped high into the air, and attacked the attacking Heartless. The dragon took off into the air as soon as possible.

Donald was using magic to kill the Heartless, and Goofy was throwing his shield. Kairi attacked the smaller Shadows. Even with the help of the small group of men, it took a while to dispatch all of the Heartless.

Everyone was worn, but there were no severe injuries. The dragon landed, and eyed Sora and friends with an icy stare.

"Saphira wants to know whom she is thanking," one man, who had slightly angled features and pointed ears, said.

"I'm Sora, this is Donald, Goofy, Riku and Kairi," Sora said.

"I'm Eragon, and Saphira here is my dragon. What were those things that attacked us?" the man, Eragon, asked.

"Those were the Heartless," Donald said.

"They're almost everywhere we go," Goofy added.

"So your world isn't the only one with that problem," Sora said.

"It's a new one for sure. We were on our way to take care of four of the many problems in Alagaesia. The biggest one is one we can't tackle until I become stronger. Wait, did you just say our world? You're not from here?" Eragon asked.

"No, we're not," Sora said.

"There are tons of other worlds out there," Goofy said.

"Yeah. We're visiting worlds we've never been to, to open up routes between them," Donald said.

"We've already hit all the worlds we've visited before," Sora said.

"Some wouldn't believe you. I do, though. We are on our way to eradicate this world of four foul creatures. Two Lethrblaka and two Ra'zac," Eragon said. "The Ra'zac are designed to hunt humans, and the Lethrblaka will eat anything. While the Ra'zac are cunning, they do not posses the intelligence their parents have."

"Lethrblaka are huge and winged, resembling starved dogs, have long necks and long spear-like beaks," another man, who very vaguely similar to Eragon. The resemblance would have been more noticeable if Eragon didn't have angled features or pointed ears.

"This is Roran, my cousin by birth, Brother by right," Eragon said. "We better get going. Our foe can see better than any human at night."

"We'll come along. What would you do if more Heartless came? You're not used to fighting them," Sora said.

"Hmm. I have a question. My sword didn't work against the Heartless, but Roran's hammer did. Why is that?" Eragon asked.

"I'm not sure. Not all weapons work against the Heartless," Sora said.

"Your strange weapons work fine on the things," Eragon said.

"The Keyblade… well, one function is to destroy Heartless," Sora said.

"There are different Keyblades. I carry one myself, and Kairi, when she does fight, also has one," Riku said.

"Oh, and King Mickey has one too," Donald said.

"Who's King Mickey?" Eragon said.

"The one who sent us on this quest. He wants the worlds open and free to trade," Goofy said.

"You haven't seen someone yea high with large rounded ears wearing red and black, have you?" Sora asked.

"Apparently, he went off again," Donald said.

"No, I haven't met anyone of that description," Eragon said.

"Well, it was worth a try. Maybe he'll show up later. Eragon, what's the 'biggest problem' that this world has?" Sora asked.

"King Galbatorix. King of the Empire," Eragon said.
