The Ultimate Darkness

Chapter 1: Into the Darkness

As the Gummi ship soared in the void between worlds, Sora laid back in his chair. After beating the Hydra at Olympus, he was beat. "Hey Goofy, you mind dimming the lights? I wanna catch some Z's." Sora asked sleepily.

"Uhhh…sure, Sora." He got up, walked over to the switch, and was about to touch the light switch, when he heard a LOUD interruption.

"Don't touch that switch!" Chip yelled. "Open your eyes!" roared Dale. "We're coming up on something big!" Chip pointed. "Check it out, guys!" Dale pointed as well. Sora, Donald, and Goofy ran to the windshield of the Gummi ship and were amazed.

"Wow!" Sora exclaimed. "It's amazing! It's a big, beautiful palace, and there are cities, hills, mountains, forests, rivers! It's beautiful! Uhh…what is this world?

"This world is called Ivalice." Chip said. "It may look beautiful now, but wait until we come closer. You'll be in for a rude awakening."

And they waited. As the seconds passed, the world grew bigger as they approached it. And as they came closer, their hearts sank more and more. Because the closer they came, the more they came to realize that it was shrouded in darkness—more darkness than they had ever seen in their lives.

"What in the world?" Donald yelled.

"Our sensors picked up all the darkness before it was visible." Chip said.

"That's horrible! Do you think it's the Heartless? Or Malificent?"

"I don't know…" Sora said. "But we have to find out what it is. Full speed ahead, Chip and Dale!"

"Aye aye, sir!" They both said in unison, and went back into the control center. Sora stood their arms folded. This is going to be a big job. Next thing, they felt a big boom as the Gummi Ship dashed forth. Donald and Goofy fell backwards, but Sora stood in place. He had a bad feeling in his heart.

As they came closer to the world, they got ready to get through the darkness. Hopefully they would not get ensnared in it. As the Gummi Ship came closer and closer, it seemed to go faster. But then something unexpected happened. Something that looked like a boat with propellers that floated in the air, which was much larger than the Gummi Ship, appeared in front of the Ship! The crash that followed was horrible for those in the Gummi Ship. The ship exploded around them, but Sora's Reflect magic blocked them from harm. But all of a sudden his Keyblade disappeared in his hand. Chip, Dale, Donald and Goofy fell into the darkness, their screams faded slowly. Sora saw two boys and a girl fall from the boat, into the darkness as well. To avoid falling, he grabbed onto a few broken planks on the boat where the Gummi ship crashed, and braced for landing. The boat fell in a vertical downward direction, and Sora was absolutely sure it was going to crash. He closed his eyes, and felt the cold of the darkness rush upon his skin. It stung so badly. He was afraid he couldn't take it anymore. But eventually the stinging stopped, and he felt warm. He opened his eyes to see a see a beautiful, wide open sea near an island. The boat then began to fly again. It landed on top of the water, and then the propellers went back inside the hull and were replaced with sails. Sora went inside the small hole that was created by the Gummi Ship, and looked for stairs. When he found them, he went upstairs.

When he got to the deck, he saw a figure Sora's size from behind wearing black and purple armor at the wheel. A heartless! Sora thought. He put out his hand and the Hero's Crest Keyblade appeared. Usually heartless would turn and attack at the first sign of a Keyblade. But this one didn't move. Sora took a step closer, and walked up slowly. When he was right behind the heartless, it turned around faster than Sora could see and pulled out two swords, one crimson red, and one beautiful silver. They slashed Sora across the chest, knocking him into the air. When in the air, he performed Aerial Recovery and then came down to perform an Aerial Spiral. As he came towards the heartless, he realized it wasn't a heartless at all! It was a boy in black armor, about Sora's age, with silver hair. The boy did a roll to the side, but Sora's Keyblade managed to tag his leg. A little injured, the boy stopped on the ground and knelt for a second. The boy looked up and realized Sora was standing in front of him with his Keyblade about to strike his heart. At the last second, the boy pulled out his two swords and tried his best to push Sora's attack away. At first it wasn't working. He could see Sora was getting cocky. But the boy had another trick up his sleeve. The boy's eyes winced, and Sora could see he was in pain. Was it his leg? Or something else? He then saw what looked like darkness creep up on the boy's swords. Sora was about to pull his keyblade away, but was frozen in his place when he saw the boy's eyes go completely black, and Sora felt a huge, painful pulse was sent flying back. His back hit the mast of the boat, and his Keyblade disappeared. He was down for the count.

He saw the boy's eyes go back to normal, but were still filled with anger. If this boy wasn't a Heartless yet, he sure would be soon. The boy walked up to Sora, his silver sword sheathed, but his crimson one out and pointed right at Sora's throat. "Who are you?" he said in a voice that was as deep a pitch as Sora's. "Where are you from? Why did you crash into my ship? I suggest you answer them."

"Give me a—urgh—chance to answer, will ya?" Sora said. The boy exhaled. "I'm Sora. I'm from Destiny Islands. I came here on the Gummi Ship because my pilots Chip and Dale found that this world was covered in darkness. We expected it might have been the heartless, so we decided to take a pit stop, which was when your huge boat appeared out of nowhere, and we crashed into out, completely DESTROYING the Gummi Ship. I managed to protect everyone from falling into the darkness, but apparently there was too much darkness and it overwhelmed my Keyblade, causing it to disappear and so did the shield. Chip, Dale, and my friends Donald and Goofy fell and disappeared into the darkness. I managed to catch onto your boat where the Gummi Ship crashed. When we landed I popped in, and thought you were a heartless. So we fought, you kicked my butt, and here we are."

The boy stared at Sora for what seemed like 30 seconds. He obviously hadn't the foggiest of what Sora just said. After a while, he sheathed his crimson sword. Sora got up, and cast Cure on his leg. The boy looked at Sora and smiled.

"Thanks…maybe you're more trustworthy than I thought."

"Of course I am. But can I ask you something?"

"What?"

"Are you a heartless?"

The boy looked at Sora and raised an eyebrow. "Last time I checked, I was Luneth."

"Luneth? What's a Luneth?" Sora stepped back as if to take a fighting position.

"It's my name, not a race." Luneth chuckled. "As for a heartless, I don't know what you're talking about, because I find myself very kind to people and not at all heartless."

"No…a heartless is when someone succumbs to the darkness in their heart and it takes control of them, transforming them into monsters of pure darkness." Sora explained.

"Ahh…and you figured because of my black armor and the fact that I can use darkness to hurt enemies, I was one?" Luneth chuckled. "Well, you're kind of going in the opposite direction. I'm Luneth, one of the four Warriors of Light. Our purpose is to use the power of light to stamp out the darkness that threatens our home. If we restore the light to all of the Crystals of Light and stop the growing darkness, the equilibrium will be restored and we will be at peace. If not, the imbalance will set free the void and threaten to engulf the world."

"Damn." Sora said, pretty impressed. "My whole purpose is to use the Keyblade to connect all of the worlds that have been separated…and I have to stop the forces of evil, including the Heartless, and the Nobodies, which are the body and soul left over when a Heartless is created. The 13 strongest Nobodies are called Organization XIII, who are in charge of all Nobodies. Organization XIII is up to something…we don't know yet…but what they're going to do is a threat to all worlds. Mine, yours…everyone's."

"Ah." Luneth said, also impressed. "Interesting. Well, I'm going to drop anchor. Luckily the hole from the Gummi Ship was kind of high, so we won't be taking on any water. Now let's see if we can go anywhere. Preferably somewhere that has food, because Ingus and Arc pigged out on our last stash of food."

Sora immediately spotted a forest that had trees on it near the beach. "There! It's closest, and we might find some food!"

"Good thinking. After we get food for the journey we can make our way to a city and find a place to stay." Luneth agreed. "All right, let's go."

"So, where are the lifeboats?" Sora asked.

"Lifeboats? What lifeboats? There are no lifeboats. This isn't a boat, dude. Well, not entirely. You saw it for yourself—it's an airship! The top quality airship, designed by Cid Haze himself!"

"Cid Haze? I think you mean Cid Highwind. And trust me, he makes stuff a lot more high-tech than this, no offense. You saw the Gummi Ship, right?" Sora said, eyebrow raised.

"No, I mean Cid Haze. The Airship designer for King Argus. Maybe Cid Highwind is his distant cousin or something, but Cid Haze is famous for this baby. Durable…fast…convenient. What more could you want?"

"Lifeboats." Sora smiled.

"If you really want lifeboats so bad, here!" Luneth took out what looked like a piece of cardboard. He threw it to Sora.

"What is this?" Sora asked.

"It's a foldable canoe. I mostly use it for rivers and crap, but considering our landing was kind of sudden, and I didn't think before dropping anchor, we're gonna have to hope it gets us to shore. Throw it into the water."

Sora did as he was told; he threw the small piece of cardboard into the water. At first, it just floated. Then it unfolded more and more and more until it took the shape of a canoe. Luneth dove into the water, and Sora watched him climb into the canoe. Sora did the same. They then started rowing to shore. When they got out, Sora looked at the trees. These trees were amazingly huge. They didn't look that big before. He had never seen a tree this big.

"Where are we?" Sora asked.

"Nubswood." Luneth replied instantly.

"How did you know that?" Sora asked. Luneth pointed to a sign that said "Nubswood". "Oh."

"Now stop horsing around, let's look for food." Luneth chuckled.

They walked deeper into the Nubswood, and the farther they went, the less sunlight shone through. But they paid no notice. As they walked, they began to lose their sense of direction. Eventually they were lost. And to top it all off, monsters appeared when they entered a clearing.

"What the hell are those things?" Sora asked. "They aren't Heartless!"

"They're nothing I've seen either. Does each world have different monsters?"

"It's possible. But I doubt my Keyblade will have much effect on them."

"Let's try anyway." Sora summoned his Keyblade, and Luneth pulled out his two weapons. Then something weird happened. There was a flash of light about thirty meters away from them. Out of the flash of Light appeared a man in elegant silver armor, with a sword in his holster and riding an armored Chocobo.

"Engagement declared." The man announced. "Today's laws indicate: Use of Instruments and Lightning are forbidden and will result in a yellow card penalty. Use of Knightswords and Wind are recommended and will result in one Judge Point Reward."

"Laws? Judge Points?" Sora asked.

"Knightswords? Instruments?" Luneth followed. Both hadn't the foggiest what was going on.

They found themselves all the more helpless as the monsters backed them against trees.

"Luneth, what are those things?" Sora asked, panicking.

"They look like goblins," Luneth replied. "But it's not them I'm scared of. It's that guy riding the Chocobo. He said there are laws. What if killing these things is illegal?"

"It's not. Not today at least." They heard a voice, a voice of someone their age, what seemed like the voice of a savior. All of a sudden, one of the Goblins' eyes opened extremely wide. It hunched over, and Sora and Luneth saw a sword in its back, a sword that shone as elegantly as the eyes of boy who wielded it.

"So, are you going to stand there, or are you gonna help me?" The Goblin, still alive but pretty wounded, got back up. The boy took out the sword, and used his shield to parry the incoming punch. He then spun around and slashed it across the chest. In a puff of smoke, it appeared on the ground, seemingly dead.

Sora called up his Keyblade, and jumped in the air. Then he flew towards a Redcap and did a spinning attack. The Redcap recovered from the blow, and lashed out at Sora. Sora guarded with his Keyblade, and then slashed the Goblin. In a puff of smoke it fell too.

Luneth, however, was doing a bit more work. Since he had two blades, He took on two enemies. He used his red sword to wound one goblin, and he smiled, as if it felt good for some reason. Then his eyes filled with purple, his swords went black. The two goblins were sent flying, and went in a puff of smoke as they hit the ground.

"Engagement over!" announced the man in silver. "Victory goes to: The Unnamed Clan!"

"Unnamed Clan?" Luneth asked. "Since when are we a clan?"

"Don't question it. Just follow me. We should head back to Sprohm for a drink and some rest. And I'd like to talk to you guys, if you don't mind." Sora examined this boy as he talked. He could see he wore a blue tunic and brown pants, and had a sword holster on his side, but over it he wore beautiful gold armor on his torso, and purple, pointed boots. His eyes shone with a brilliant blue, his hair an elegant yellow.

"All right, let's go. How long is the trip?" Sora asked.

"It'll be about a day. I'm Marche, by the way."

"Sora, and this is Luneth." Luneth waved as Sora introduced him.

"Well, follow me guys." Marche repeated, and they were off.
