The Mummy of Darkness Returns.

Author's note: Hello and welcome to another crossover. Due to my previous crossover story "The Mummy of Darkness" requested by my friend Bopdog111, this is a sequel requested by another fellow author KingdomWarrior125. I will try my best with it, but it's mainly a sequel to this story as well as a spin-off of "Kingdom Hearts III: Second War" to make things easier.

I do not own Kingdom Hearts or the Mummy. Kingdom Hearts belongs to both Square Enix and Disney, while the Mummy belongs to Universal Studios.

Chapter 1: Future Dark Calling?

During the events of "Kingdom Hearts III: Second War", in Chapter 41...

The entire Coliseum building glowed in light and instantly Sora's Keyblade appeared in his hand, which made the worldly travellers realised that again he was going to lock this world's keyhole.

Nodding, the teenager held it out as the crown shape appearing underneath him as the world's Keyhole appeared via a beam of light shooting out from the Coliseum Building. Sora then thrusted the Kingdom Key upward and via another beam of light, he locked up the world's keyhole, protecting it from the darkness before things returned to normal.

"That was a fancy light show." Gladio admitted, amazed.

"That never stops being amazing." Noctis smiled, still amazed, as were Prompto and Ignis.

"You guys be careful out there and come back soon." Hercules told Sora and his companions who all nodded.

"We'll meet up again soon, right?" Noctis asked.

"Yeah, you bet." Sora nodded.

Mickey, knowing that they still had more worlds to attend to as well as figuring out how to solve the current situation, said, "C'mon, fellas. Let's get goin'."

But just as the worldly travellers were about to respond and to share their promise to Hercules's group and Noctis's group that they'll meet up soon, there was another flash of light which got everyone's attention. As they looked up, they saw something beginning to form in the sky, like a corridor of light or a portal.

"What's going on?" Goofy asked, confused.

"What's that bright light?" Mickey asked.

Before anyone could answer that, the light began so bright that everyone had to shield their eyes as they cried out in alarm when it engulfed the entire area in front of the Coliseum, with Sora, Riku, Kairi, Mickey, Donald, Goofy, Lea, Noctis, Prompto, Ignis and Gladio all screaming the loudest as all ten of them felt as though they were being pulled before they lost consciousness. When the light faded, everyone lowered their arms while opening their eyes, and everything seemed to return to normal.

"...What was that about?" Ven asked, dumbfounded.

"Wait! Where are Lea, Sora, Kairi, Riku, the King, Donald, Goofy, Noct, Prompto, Ignis and Gladio?" Xion cried out, as she was the first to notice ten of her friends' sudden absence and it took the rest of the group to realise that the former replica was right. Ten of their friends were indeed missing and they quickly began to grow very worried.

"Did that light take them? Where did they go?" Roxas asked, very worried.

"It better not have our enemies' names on it." Terra grunted, clutching his fist. How could this have happened?

Wherever did their friends go, or perhaps the better way to say it, is whenever did their friends go, was a mystery that would have to be solved by Sora's group themselves as they were in for one of the toughest and most dangerous adventures of their lives.

Seven years into the future...in the world of Egypt: Hamunaptra-The City of the Dead.

Hamanaptra, the City of the Dead. Once used for storing the wealth of Egypt, it was now a memory...if you didn't count the huge excavation that was in process, though. The diggers were watched over by men in red turbans clutching rifles.

Nearby in a small campsite, were two people, one black and deadly looking, and a woman who seemed rather familiar. On the table that was set up, were two stone and gold books. The man with the dark skin gently placed the black book onto the table.

"The Book of the Dead gives life..." He said with a cruel smile.

"And the Book of the Living..." The woman, with long black hair, blew dust off the golden Book she was holding. "...Takes life away."

"I thought that was my job." The man pouted with a smirk.

The woman smiled cruely in return. "We're getting close."

Back with Sora...in London of the same Egyptain World...

How long had the ride lasted felt like forever for Sora and nine of his friends who ended up losing conscious, but when they neared the exit of the weird tunnel of light that absorbed them, they woke in alarm as they fell through and landed hard onto the ground with thuds.

"Ow...that wasn't fun." Sora grumbled, rubbing the back of his head, before noticing that something felt oddly different, as his hands felt a bit bare when he touched his head. Blinking in confusion, the sixteen year old lowered it and saw, to his great confusion, his fingerless black gloves were gone! Instead, he was now wearing black and golden material gauntlets that went up to his elbow, and on the back of his gaunlets when he looked at his hands, they had white circles that reminded him of his old white fingless gloves when he was fourteen.

Standing up in confusion as did his friends, Sora exclaimed, "Hey! What happened to my clothes?" when he realised his entire clothes had changed completely. It had become a mixture of both his clothes he retrieved at the Mysterious Tower, and those he wore when he and Riku entered the Realm of Sleep, only it was black and gold, and in the middle of his chest was some kind of symbol of a halo.

The only thing that was the same was his crown chained necklace.

"My clothes are different too!" Riku cried out, shocked. His clothing now looked a bit like what Noctis was wearing, except his undershirt was white, and there were blue and black patterns on the bottom of his new dark purple long-john shorts. He also wore two black plain fingerless gloves and black shoes.

"Mine too!" Kairi added, as she now where a coat-like short pink dress with pockets and buttons, a pink a black hood that went with it, new silver bracelets and leather black short boots. When Sora looked at her, his eyes widened slightly at her new look. Even her new outfit was gorgeus on her.

Mickey too rechieved new clothes. He wore a black shirt underneath his new short-sleeved jacket that had a hood with around ears to cover his entire head, red shorts with the bottom having the same pattern as Riku, only red and black, and his shoes were black and yellow with dark gray shoe laces. As did Lea who now wore a black short jacket that was a mixture his the upper part of Axel's black coat that went down to his hips and his jacket he had been wearing since getting them from Merlin, dark red pants with shoes that resembled to Reno's shoes and Axel's boots and fiery patterned shirt underneath the jacket.

Everyone else's clothes were exactly the same and that wasn't the only thing weird going on. In the area they were in, they were in front of a large mansion in a large courtyard of a large olden city which reminded Sora, Donald, Goofy and Riku of London in Neverland. On top of that, the rest of their friends weren't with them.

"Uh...where the hell are we?" Noctis asked, confused as he didn't recongise this place.

"Are we in another world?" Prompto asked, looking around.

"What was your first clue?" Gladio responded sarcastically.

"I think the question is, how did we get here?" Ignis pointed out, ignoring Gladio's sarcasm.

Mickey folded his arms in thought, before remembering that light and said, "Gosh, it must've been that light back at the Coliseum. Whatever it was that brought us here, it must be because we were meant to come here for a reason." and then admitted, "And gosh, this place feels sorta familiar."

"Yeah, now that you meantion it, I feel like that we've been here before." Riku nodded in agreement, and his eyes narrowed in suspicion and concern. He could feel familiar darkness around here, and that wasn't a good thing. The question was, why?

"Yeah, I'm gettin' that feeling of deja vu too. Even though I don't recongise this house, the world itself is really familiar." Lea added, and on top of that, he could feel the pressense of Axel inside him despite the two having been completely fused since the incident of the Brotherhood of Darkness shortly after the demise of Organization XIII.

"Really?" Sora asked, blinking in confusion. He then turned to Donald and Goofy, inquiring with one shoulder shrug, "Ring a bell?" only to rechieve dumbfounded and confused shrugs from both of them.

He turned to Kairi who shook her head and said, "I don't know this place either."

When Sora turned to Noct's group, the Prince quickly said, "Don't look of us. We've never been here before either." and his three friends all nodded in agreement.

Sora was about to ask Riku, Mickey and Lea further on why this paticular world was familiar when the sound of a car horn caught their attention and when the ten of them looked, they saw a 1930's car approach from a very long driveway and slow to a stop. As the three of the four doors opened up, three people came out; one was a man in his mid thirties and appeared to an explorer or gunfighter with short brown hair and blue eyes, another was a woman, a bit younger than him, with curlish dark hair and beautiful eyes, wearing a black long dress and high-heels, and the last one was an eight year old boy with hair similiar to the older man's, and clothes a little bit like his too, wearing a brown material jacket.

And somehow, Riku, Mickey and Lea recongised the two adults.

"Rick? Evelyn?" Riku and Mickey asked in unison, surprised as was Lea who blinked. Now they realised where they were; this was the world the three of them ventured into shortly after the events at Castle Oblivion two years earlier.

"Riku? Mickey? Axel?" Rick asked, dumbfounded himself as was the woman, Evelyn, or Evy for short. "What're you guys doing here?"

"Uh...by accident, I suppose?" Riku shrugged, somewhat awkwardly.

"Do you know them?" Sora asked his best friend, the King and the former Nobody.

The older teen nodded, "It's a long story."

"Mom, Dad. Are they the people you told me about?" The little boy asked to the two adults.

"Mom and Dad!?" Sora's group exclaimed, shocked. But none more so than Riku, Mickey and Lea.

"Oh yes, this is our son, Alex." Evy smiled, her expression turning to happiness to see three of the people she hasn't seen in a long time before turning to her son and gestured him, "Say hello, Alex."

"Hi, nice to meet you." Alex waved, quickly eager to meet the trio. "I've heard a lot about you guys and I've always wanted to meet you!"

"Uh, thanks, kid." Lea said, awkwardly, before looking up at Rick and Evy and quickly corrected them, "And just so you guys know, Axel's my nick-name. My real name's Lea. Got it memorized?"

"So, um...h-how long has it been?" Mickey asked, almost hesitatedly. If Rick and Evy had a son who looked much like his parents, then he had a feeling that the portal did more than just take him and his friends into this world.

Evy's answer pretty much confirmed it. "It's been nine years."

"NINE YEARS!?" Sora's group all exclaimed, shocked.

"You've gotta be kidding me." Gladio muttered in disbelief.

"That can't be right." Riku shook his head. "For the three of us, it's only been two years since we met you guys. I'm seventeen now."

"...What?" Rick asked, dumbfounded.

"Only two years? That can't be right." Evy said, twice as confused.

"What is going on here?" Donald asked.

Goofy tapped the side of his head, trying to think before like Mickey, came to a conclusion and said to the group, "Gwarsh, that portal that swallowed us up musta brought into the future and changed the clothes of all five of you at the same time." while gesturing at the sudden transformation clothes on Sora, Riku, Kairi, Mickey and Lea.

"You're right, Goofy. That's the only explaination I've come up with." Mickey nodded in agreement.

"So...we're in the future?" Kairi asked, stunned and shocked.

Noctis shrugged awkwardly, "Well, that explains a couple of things. Problem is, why did it bring us here in the first place?"

"You mean you can travel through time? Neat." Alex thought, amazed and his mother shared that as well as feeling a bit concerned.

Rick on the other hand, looked a bit spooked. "Oookay...that is practically weird."

"Well, why don't we all go inside and figure this out as well as what we found earlier." Evy suggested.

"Is it alright with you, madam? We don't want to be a burden." Ignis inquired.

"Don't be silly. Of course you can all come in." Evy replied.

"Gosh, thank you Evy." Mickey smiled, warmly.

"Of course." Evy nodded, and Alex looked thrilled while Rick, even though he was glad to three of their friends again, wasn't looking forward to more puzzle solving. She then asked the others, "And, you all must be friends of Riku, Mickey and Ax-I mean, Lea."

"Yeah." Sora nodded, smiling as he introduced himself and the others, "I'm Sora, and this is Kairi, Donald, Goofy, Noctis, Prompto, Gladio and Ignis."

"Nice to meet you." Kairi nodded with a kind smile, while Donald and Goofy both waved.

"Hey there." Noctis and Prompto added.

"My pleasure." Ignis greeted.

"Hi, how ya's doing." Gladio greeted last.

Even though this meeting seemed normal despite what was happening, little did Sora and his friends know that the reason for them being summoned into the future was far more sinister than they thought, because something is about to happen on this very same night in this future.

A/N: Hope you liked this beginning so far, KingdomWarrior125. I'm doing my best with it and the next chapter will be the start of the big adventure. It'll probably be a slow process and well, things will be happening for the next two months. Hopefully I'll post the next chapter soon.
