This is a continuation to my version Kingdom Hearts III and will give you about a hint on how my Kingdom Hearts IV will go. I should also mention that my Kingdom Hearts IV story will not only have worlds from Disney, but world from other places like Dreamworks.

Lanes Between

Terra was on his Keyblade Glider, flying in the Lanes Between, and Aqua and Ven were close behind. He still felt guilty about everything he did from listening to Xehanort from killing Master Eraqus. Also he feared that the darkness in his heart might try and leak out again.

"Terra, you feeling all right?" Ven asked.

Terra looked back that them. "Don't worry I'm fine," he lied.

Even though he couldn't see Aqua's face, it was clear that she didn't believe him.

"Terra, you don't have to lie to us," said Aqua flying next to him. "We're your friends and friends help each other."

"Yeah, you don't have to carry everything on your shoulders," said Ven coming alongside him.

"Guys… I'm just worried that the darkness will take over me again," said Terra.

"That's not going to happen," said Aqua. "If Riku is able to conquer the darkness inside of him then you can do the same."

"But it clear that Riku is stronger than me," said Terra. "I mean… look on my home world we were always… head strong…"

"But unlike Riku apart of you was able to fight back against Xehanort," Aqua reminded him. "Though you've always been stubborn."

Before Terra could say something a new world was coming into view. It was new to Aqua and Ven, but Terra knew this world all too well.

It was covered in water, but there were islands dotted all over the place. Far north there was a huge ice glacier.

"What is this world called?" Ven asked.

Aqua looked down on the monitor of her Keyblade Glider, but before she could speak Terra said, "The Barbaric Archipelago."

Aqua and Ven looked at Terra stunned.

"How did you know it was called that?" Aqua asked.

"Because… I've been here before…" said Terra not looking at them. "It's my home world."

Barbaric Archipelago: Icy Wilderness

Moments they landed on the Barbaric Archipelago and the first thing they saw was that they were on some kind of icy wilderness. There was nothing but snow and ice and only about a mile away was a mountain with icy spikes sticking out of it.

Aqua and Ven were looking at Terra not sure what to say. Aqua then broke the silence and said, "So this is where you're from."

"Not exactly," he said not looking at them. "You saw those islands, I was born on one of them. I've never set foot on this part of the world."

"So… tell us about this world of yours," said Ven.

"There's not really much to tell," said Terra still not looking at them.

"There's something you're not telling us… isn't there," said Aqua curiously.

Terra stopped and turned to face them. "All right… I'll tell you," he said. "I lived on an island called Berk… we were fighting in a war… us against dragons—"

"Wait—you were fighting dragons," said Ven eyes widened.

"Yeah, for nearly three hundred years," said Terra. "The battles were brutal… it was kill or be killed. I was about your age Ven when Master Eraqus found me. He saw something inside of me but I do know myself… so it made me his apprentice and the rest you know."

"You should go back," said Aqua. "At least determine that your life. I mean it's been about twelve years since you last saw them."

"No!" said Terra firmly. Then it all looks on their faces. "Sorry... just I wasn't that popular back home and neither was my sister."

"You have a sister!" said Aqua stunned.

"Yeah… I did," Terra corrected. "Listen guys I just wanna talk about it."

After that they didn't talk much they just continued walking towards the mountain with ice spikes sticking out of it.

Barbaric Archipelago: Icy Caverns

They soon entered into a cave in the mountain that turned out to be a tunnel. It was so dark in the tunnel that Terra couldn't see his hand in front of his face.

"Hey, Aqua?" said Terra. "Why don't you shine some light on things?"

Aqua nodded and summoned her Keyblade and then shone some light from its tip.

The light helped at least they could see where they were going, but Terra still felt bit nervous like someone was watching them.

They soon reached the end of the tunnel and enter into a cavern. The cover was large and in the distance Terra could see another tunnel and to his right he could see a giant wall of ice.

"Should we go down there?" said Ven gesturing to the tunnel.

However, before Terra could say anything, something slammed into. Once he got a good looking, he realise that it was someone wearing armour and holding us strange staff.

Aqua and Ven summoned their Keyblades and charged at the armoured figure. However, the armoured figure was prepared, he raised his staff and blocked their attacks and then leg sweep them of their feet.

By this time, Terra had recovered from the shock and stood up. He summoned his Keyblade and pointed out the armoured figure.

"Who are you?!" he demanded.

The armoured figure turned to face Terra and charged at him as he twirled his staff. Terra raised his Keyblade and block the attack. The two of them stared at each other and then, suddenly, the armoured figure gasped.

"Terra!" said the armoured figure and Terra realised that he was a she.

Terra pulled away and stared, and from the looks on their faces both Aqua and Ven were confused as well. How did she know his name?

"After all these years," said the armoured figure breathlessly. "How is this possible?"

"Do I know you?" said Terra raising an eyebrow.

"Yes," said the armoured figure as she removed her helmet. "But it has been fifteen years since we last saw each other…" When her helmet was removed, Terra saw a very familiar face, one that he had not seen for fifteen years, and gasped, "Brother."

"Valka!" Terra exclaimed.

Indeed it was Valka, his younger sister, now looking twelve years older than him. She hasn't changed she matched, she still had her blue eyes and her brown hair, but she was as tall as he was.

Valka slowly approached him, staring at him like she was seeing a ghost, raising a hand towards him. "You've barely changed," she said.

"A lot's happened," said Terra not looking at her in the eye.

Valka redrew her hand and looked at him then to Aqua and Ven, who both were still dumbfounded. However, before anyone could say anything, Heartless appeared out of nowhere.

These Heartless were about the same size as Pirates, but they had Viking helmets instead of bandannas and battle-axes instead of swords.

"These creatures again!" said Valka twirling her staff.

"Heartless!" said Terra raising his Keyblade.

The first Viking—that's what Terra decided to call them—charged at them, but Terra sent it flying with us swing of his Keyblade. Aqua and Ven, who have recovered from their shock, charged at the next group and slice them with their Keyblades. Valka swung her staff at one and use another pole vault to jump over another one and slammed her staff at its back.

However, more and more came and soon they were getting overrun backing them into a centre of the cavern.

"We're getting outnumbered here," said Ven blocking a Viking's sword.

"I could create a magical barrier," said Aqua.

"That'll only slow them down…" said Terra slamming another Viking with his Keyblade.

"Well, I hope someone got the idea," said Ven.

"I've got one," said Valka.

Before Terra could ask what it was, Valka swung her staff around creating a whistling noise. Then they heard roar in all directions.

"What was that?" Aqua asked nervously.

"Oh, just a friend of mine," said Valka.

Suddenly something big and scaly jumped over their heads. Terra couldn't believe his eyes, standing in front of them, biting down on the Vikings, shooting flames at them, was a dragon. The dragon is twice as tall as he was and had four wings, its head resembled that of an owl.

"What is it that?" said Ven

"Oh that my partner… Cloudjumper," said Valka

They watched as the Cloudjumper took down the remaining Vikings.

Terra stared at Valka in disbelief. "Explain!" he said.

"However we talk all over it over something to eat," Valka suggested.

Barbara Archipelago: Dragon Sanctuary

Valka had let them with the tunnel they saw earlier and they found themselves in what can only be described as an oasis. In there they saw other dragons flying around, including an enormous one that was over forty feet with massive tusks.

Aqua noticed that some of the dragons were injured… some had their wings ripped and others missing a few limbs.

However, she was more focused on Terra, she noticed that he was mostly focusing on his sister. Looking at her Aqua could see the resemblance both pretty much have the same build and the thing determination their eyes.

Valka, began preparing some food in a cavern Aqua guessed was where she slept. As she prepared food, Terra explained everything that happened over the last twelve years.

"I was quite surprised seeing you here," said Terra after he finished. "Last I heard you were engaged to the son of the chief."

Valka stopped what she was doing. "I was," she said sadly. "And we got married."

Aqua could tell about Valka didn't want to talk about it, but the boys, as ever, were clueless.

"Then will you doing here then?" said Ven.

Terra looked as if he was about to say something, but Aqua cut across him. "Hey, how about I help you?"

Without waiting for an answer, Aqua rushed over to Valka and helped her preparing the food.

"Thanks," Valka whispered.

"We goes on to girls together," said Aqua. She looked at Valka. "You know you don't have to tell me, but I'm here if you want to talk."

Valka didn't say anything. In fact say anything over dinner, which was terrible, and she didn't say anything while they cleaned up. It was only when the boys were sleep that she approached Aqua and sat down next to her.

"Terra and I weren't very popular where we grew up from," Valka explained. "I do know if Terra told you, but we were at war with dragons."

"Terra did mention it," said Aqua.

"Well… on Berk it's kill or be killed, but me and Terra wanted to end the mindless killing and because of that we were extremely unpopular," Valka sighed. "Terra believed that becoming a Keyblade Master was the key… so he left with that Master Eraqus. Me on the other hand… well-being the chief's wife I tried to persuade him to find a better way, but he was extremely stubborn… then one day Cloudjumper found his way into our house where our infant son was. I entered the house… but then I saw the proof that I'd been looking for. Cloudjumper wasn't the mindless beast he was curious of a son, he did, by accident, left a scar on his cheek, but he was no mindless beast. Of course then Stoick, my husband, stormed in thinking that Cloudjumper was there to harming us. Cloudjumper attacked and the house got burned down… it was then that I decided to leave… I saw Stoick holding our son, Hiccup, heartbroken as I was carried away."

"You left your husband and your only child behind," said Aqua in disbelief.

"It broke my heart… to leave them… but they nearly died because I wouldn't kill a dragon…" said Valka as a tear rolled down her cheek. "They're better off without me."

Aqua didn't believe that, but decided not to say a word.

"Besides, I'm needed here," said Valka. "There's this man, Drago Bludvist, he's capturing dragons and enslaving them. Cloudjumper and I have been rescuing them and bringing them here so that the Alpha can protect them."

She gestured to the large dragon that was sleeping in the middle of the Dragon Sanctuary.

They didn't speak after that and Aqua fell asleep.

Barbaric Archipelago: Icy Wilderness

Next morning, Valka and Cloudjumper were seen them off.

Terra gave Valka a big hug. "I'll come and visit you now and then," he said.

"I'll be fine," she said smiling. "You just protect the multi-verse from this Organisation XIII."

The activated their Keyblade armour and summoned their gliders. They hopped on them and flew up into the sky.

"It was great seeing sister," said Aqua looking at Terra.

"Yeah," he agreed. "I just wish I knew why she was here."

She knew this was family business, but as the older brother he had a right to know. "Terra… there's something I need to tell you."

Then they entered through the portal.
