Author's Note: Sorry that it's slightly late, but I was having trouble earlier. In anycase, let's continue.

I don't own Kingdom Hearts or Final Fantasy. Warning: The opening text is a spoiler to the real KH3(and I think this will be the same opening text to the actual game).

CH1: Dream and New Beginning.

(Opening)

Sora is seen sleeping on the Beach of Destiny Islands when the ground suddenly disappears and he is in his Heart's Awakening, fighting the Darkside Heartless for the first time.

()()()()()()()()()

Sora then finds himself confronting Riku who is covered in Darkness and then the two are shared with the Kingdom Key Keyblade. Kairi's body disappears and her heart enters Sora's body. The trio are then seen at Hollow Castion confronting Xehanort's Heartless with Donald and Goofy, before they and King Mickey close the door to Kingdom Hearts...where Aqua had just sacrificed herself to save Riku from the Heartless Tide.

()()()()()()()()()

Aqua is seen fighting the Heartless before finding herself on the shores of the Realm of Darkness, while having flash-backs of Terra and Ventus who are taken away from her by Xehanort and Vanitas. She joins Mickey to fight them and free her friends but is forced to sacrifice herself to protect them from Xehanort's Organization XIII.

Before Sora returns to human form after sacrificing himself, Roxas is born and is discovered by Xemnas, before becoming best friends with Axel, and then Xion as the three of them sit at the Clocktower in Twilight Town, before most of Organization XIII and then DiZ forces them to seperate, Axel being forced to fight Roxas who had Xion fade in his arms, shedding tears.

Sora, Donald, Goofy, fight Marluxia at Castle Oblivion and rescue Namine who, having messed with their memories, puts them into pods to help them return them to normal, and speaks to Riku who, with King Mickey, fight the left over darkness of Xehanort's Heartless.

()()()()()()()()()()()

Axel takes Kairi who is forcefully taken by Saix and the two Nobodies think back of their time as teenaged humans, Lea and Isa, in Radiant Garden before darkness sweeps them and takes their hearts before the two are then forced to fight at the World that Never Was.

()()()()()()()()()()()

Sora and Riku fight Xemnas with Kairi, King Mickey, Donald and Goofy assisting along with Axel who, by the light of Kingdom Hearts and Roxas' wish, gains his heart and returns as Lea. Together they defeat Xemnas, and thanks to the light of Sora and Kairi's hearts, everyone returns to Destiny Islands where Roxas, Xion and Namine wait as humans.

()()()()()()()()()()()

Then the group are attacked by Master Xehanort and his new Organization XIII along with most of the Disney Villians, Hojo, the Sephiroth Remanents and Deepground.

()()()()()()()()()()()

Roxas and Lea quickly save the newly revived Isa who joins them, Xion and Namine, as Sora and Riku take on their Mark of Mastery before they, along with their allies and friends, including Cloud Strife and Vincent Valentine, take on the villians with Xion having saved Aqua who helps the possessed Terra remember her as he protects her from Xehanort, the group aided by the arrival of Kairi and Namine.

()()()()()()()()()()()

Sora and Riku successfully defeat Master Xehanort for good and his Organization XIII vanish while Terra returns to normal, and soon with Sora's newly awakened powers, brings back Ventus who falls from the sky as the heroes fall and form a circle while holding hands as they descend, having Ven and their old and new allies join them.

()()()()()()()()()()

Suddenly, the shilloutes of Chaos, Bhunivelze, Caius Ballad, and a mysterious man in a Black Coat holding Xehanort's Keyblade, along with Aced, Shalua and Shelke appear before them, glaring down at Sora and his allies and friends, before Skuld and Empher appear, but not before the latter vanishes despite Skuld's attempt to reach out to him and a ghostly image of Ven who fades like a memory.

()()()()()()()()()()

Sora then finds himself seperated from everyone and reappears in Daybreak Town at Night, where the Heart-Shaped Moon of Kingdom Hearts shines brightly in the sky and he gazes at it, also seeing five other Foretellers there; Luxu, Ira, Ava, Gula and Invi.

(End Opening)

(Sora's Dream)

One moment Sora had gone to sleep after having successfully becoming a new Keyblade Master along side Riku, and then the next moment, he found himself in a rather unusual looking place. All around him where swirls of light and stars, surrounding the rock platform that was slightly crumbled and large chunks of pieces of rock. As Sora looked a bit more closely, he blinked in shock as these stars...they were actually hearts.

The sixteen year old then gazed ahead and saw...a large familiar door at the end of the path, which made him remember of the first time Sora and his friends closed up the door to darkness after the defeat of Xehanort's Heartless. The door ahead of them...was slightly open. Taking this as a bad sign, Sora was about to head towards it when a voice behind him made him stop in his tracks.

"Wait. Do not go near that door." An unfamiliar voice spoke.

The moment Sora whirled around to see who it was that spoke to him, he was met with...a man in a long white robe, wearing a mask that resembled a Unicorn.

"Who're you?" Sora asked, supiciously.

"That's not important right now." The Unicorn-Masked man said, walking past Sora before stopping just in front of him, his back turned to the sixteen year old boy. "You're not fully ready for what is at the other side of that door. It is...far too powerful."

"But, it's slightly open." Sora pointed out, "Shouldn't we be worried, in case the darkness comes out of it?"

The man stood there, silent for a moment before speaking once more, "It's not darkness that's on the other side. It's...something far more dangerous and forbidden. However, only the one strong of heart can enter it and close it. Sadly, young man, you don't have that kind of power or strength."

"Then...how can that door be closed, then?" Sora asked, worriedly.

But when he turned to gaze at the man again, Sora did a double-take as the man suddenly disappeared, and soon the entire area was fading all around him as well, and soon his vision began to go all blurry and darkness claimed him as his world went black...

Back in Reality...almost two days after the events of "Second Life; Secret Episode"...

"Sora? Sora!"

Sora blinked suddenly as he came out of the reminisice of a dream he didn't remember of until now. Hearing Kairi having called out to him, Sora turned to see that she, along with the rest of their companions-Riku, Donald, Goofy, King Mickey, Roxas, Xion, Lea, Isa, Aqua, Ven, Terra, Myde, Skuld and their recent newest companion, Captain Jack Sparrow, gaze at him with concerned and/or puzzled expressions.

"Are you okay? What's wrong?" Kairi asked, worriedly.

Realising that, given the Gate he'd just opened with his Keyblade to reach Olympus Coliseum, Sora must've zoned out again, this time of the dream that was very unusual before their departure from the now gone Mysterious Tower. "Oh! It-It's nothing. Don't know how that happened." Sora replied, sheepishly.

"Do you usually zone out like that before we enter another world or something?" Lea asked, hsi brow furrowing in concern and slight suspicion. "That's kinda what Roxas did when he first joined Organization XIII."

"Not really." Sora shrugged. "But I'm sure it's nothing to worry about."

Roxas nodded in agreement with his former original, stating while smirking at Myde, "Yeah, when Myde used to be Demyx, he would usually fall asleep at Xemnas's speeches whenever the Organization had a meeting."

"Can you blame me?" Myde shrugged, while his face was going a bit pink of embarrassment. "Xemnas' speech were always so boring that it would've made Xaldin and Luxord fall asleep."

"You're tellin' me." Lea snorted with a smirk. "That guy would always drone about 'Kingdom Hearts' this, 'Kingdom Hearts' that. He usually just repeats the same ol' speeches all over again in pretty much all of the meetings."

"It was enough to even drive me crazy." Isa nodded in agreement, definitely not missing anything about being Saix or Organization XIII.

"Sounds like Barbossa and his over-run speeches that never goes right, if you ask me." Jack muttered sourly, which, unfortunately for the exiled Pirate, made him think about the Black Pearl which had been taken back into the depts of the Ocean in the Caribbean.

"I've never met Xehanort or even heard of him." Skuld spoke up after a few moments of silence, before asking, "Was he really that bad of a person?"

Ven shuddered at the memories of when he used to be Xehanort's apprentence, saying first to the girl who apparently was one of his friends from his origins he could not remember and thus had no idea at all, "Well, let's just say that Xehanort could tell a like like he's tellin' the truth. Really, he all cared about was starting up the Keyblade War to solve the mystery of what happened in the first war. He didn't care what would happen to the Worlds or anyone in them."

"In other words, take it as a yes." Terra added quickly.

"I figured that much given on what Ven just said." Skuld shook her head, before gazing at Sora and Riku, admitting with a smile, "I'm actually quite impressed that the two of you, not having been Keyblade Masters at the time, actually managed to defeat him."

"Well, we couldn't have done it without our friends. Otherwise, Sora and I would've been in Xehanort's clutches right about now." Riku said, bashfully while scratching the back of his head with a small blush.

"He came awfully close, though." Xion thought, shuddering. "If it weren't for Genesis or Cosmos, I don't think any of us would've been here right now."

"And without Sora, the Realm of Light would've ceased to exist as we know it." Aqua nodded in agreement, before muttering a little sadly, "Though it would've gone an entire different direction if Xehanort was prevented and defeated twelve years ago."

"And now we have new enemies to worry about." Skuld nodded in agreement, thinking about Chaos, Aced, and maybe even Bhunivelze.

Sora, while little troubled with having so many bad guys to worry about, managed to put on a brave face which became real when he quickly remembered the main reason why he and his friends with him are going to Olympus in the first place, "Well, that's nothing new. We've handled bad guys before; we can stop the new ones from causing any more trouble when we're prepared, right? And we're gonna save Master Yen Sid, Genesis and Angeal while we're at it!"

"And this time, we'll be ready for it!" Mickey said in agreement, while still saddened for the loss of Master Yen Sid, but he believed in Sora's confidence that the elderly Sorcerer is still alive.

"Yeah! And Hercules can give us a bit of a hint too!" Donald said in agreement.

"Yup!" Goofy said optimistically, before saying as that optisim quickly turned into slight worry, "But let's just hope that Hades doesn't cause any more trouble we we're there."

"And I hope that he doesn't send that giant three-headed dog of his while he's at it." Myde almost whimpered, shuddering as he remembered his time as Demyx when he first entered the Underworld. Not the most pleasent experiences he ever handled.

"Cerberus?" Jack suddenly asked, surprised. When that made everyone surprisingly turn to him, he glanced around at the new 'crew' before grumbling, "Oh, come, come, mates. I've spent half of me time readin' and learning as I grew up. I even took half of that time listening to old myths of certain history and of course most people know about Cerberus; the Guardian of the Underworld as they say. Savvy?"

"That makes sense." Riku admitted, "Plus, everybody back on the Islands knew about the old story of Davy Jones, and none of us expected that guy to be real."

"Or being turned into a mutant fish." Lea said, shuddering.

"Or having a giant octopus for a pet." Donald grumbled, sourly.

Suddenly, the Gummi-ship's radar blared, causing almost everyone to turn to the pilot's seat as Sora, Donald and Mickey gazed to see just how close they were to their destination. They and most of their friends smiled as a familiar world of giant gladiator statues was coming into view, along with a familiar building that looked as good as new.

"There it is! Ay-yhuck!" Goofy exclaimed happily.

"Oh boy!" Donald cheered.

"Welp, time to make landing, fellas!" Mickey declared.

"You got it!" Sora nodded to the king as he made to steer the gummi-ship which he and the others would then teleport into the world itself.

The world of Olympus Coliseum, where their new massive adventure was about to begin. This was the new beginning.

A/N: I know it's not much, but I do plan on making the chapters longer as I go. See you in the next chapter!
