"Everyone, gather around! We located the next Grand Star!" Polari yelled as everyone gathered
"All ready? That's a surprise." Brianna said. "Let me guess, fortress?"
"Yep. However, this is the biggest reading we ever seen!" Lubby nodded. "Something definitely is going on over there."
"The bigger reading means something powerful is guarding it." Polari nodded
"Something powerful, huh?" Aqua was on her thinking pose.
"Well, that doesn't mean it will stop us." Ventus said.
"Yeah! You got that right!" Natsu smirked.
"Still, we do have to be careful regardless." Yuri stated. "It could be anyone or anything."
"If it's Organization XIII, there's no doubt one of them will be guarding it. Or they might have a powerful Heartless or something to guard it." Alsin added.
"In that case, we'll go and defeat this monster!" Sora said as the Kingdom Hearts team nodded.
"I'm coming too." Crow said. "I'm worried about Morgan. If she's there... I wanna be there to rescue her and help her be free from Validar's control."
"Crow..." Lissa muttered.
"I'm coming too Crow." Rean said.
"I'm coming as well. There's no telling what strong foes awaits us." Byleth sad.
"Right. Count me in too." Shez nodded
"I'm coming too. Honestly, it's been awhile since I even step foot." Brianna sighed.
"All right. I have the Launch Star ready. Do be careful." Roselina said as the team who are going nodded.
The group who are going are the Kingdom Hearts Team, Rean, Crow, Brianna, Byleth, Shez, and Aether as they launch themselves to the Fell Dragon Fortress.
"Hmm..." Palutena look concerned.
"What's wrong Palutena?" Viridi asked.
"I have a bad feeling about this fortress... and who awaits on the other side."
"I agree with you as well." Mona nodded. "I tried to make divination... however, some sort of power is interfering with my divination. It's not darkness this time either."
"Something other then darkness?" Arval asked. "Maybe some power."
"Well, whatever that power that may be, those guys can handle it. Not unless they need backup." Dark Pit said.
"Right. Depending how large this fortress is. We should hope that it won't take us long." Dimitri nodded.

The group landed on the entrance on the Garden entrance, where the large door open and a portal within the reveal.
"Whoa, what's that?" Ventus asked.
"Looks like a portal. A sinister one at that." Mickey said.
"Right. There's a large setting of darkness inside." Riku nodded.
"Yeah. We better be careful as we go in." Brianna agreed.
"Right." Byleth nodded. 'Should anything bad happen, I'll use the Divine Pulse to turn back time. But if my calculations are correct and Organization XIII been researching me... there's a chance they will know about my Divine Pulse... especially with Yougn Xehanort. I need to be careful and to stop him somehow.'
"Ready, everyone?" Rean asked as he ready his Tachi.
"Ready." Crow answered as they nodded.
They all begin to enter as they walk up the stairs and then enter the sinister portal.
(Paper Mario: The Thousand-Year Door ost - Palace of Shadow - Ambience)
As they made it to the other side, the surrounding was similar to the previous stadium. However, this one has dead flowers nearby, and the dread fill the air around. The sky... or space itself is not glimmering with stars, but the background has a large blood moon behind it. The background filled with a reddish glow.
Donald gulp. "Does anyone feel that?"
"Yeah... it feels... scary." Goofy nodded.
"Paimon is getting scared too..." Paimon said shivering and frightened.
"This feeling... there's no doubt about it..." Aether muttered
"It's almost like the realm of darkness..." Aqua nodded. "The air is dread... danger is all around us."
"Right. Something powerful we ever encounter is waiting for us." Mickey nodded.
"Then we should be careful." Sora said.
"Right. Better brace yourself everyone." Crow said as everyone nodded.
They climb up the long staircase where they see an Orbal Charging Station ready to use. They use it and regain their HP to those they haven't recover just yet. After resting. They walk the hallway where the large stadium is there, but waiting for them are familiar faces.
"So you come. Well done." Validar praised and with him is Gharnef and Jedah.

(Fire Emblem Awakening ost - Id (Dilemma))
"Validar." Crow growled, restraining himself from killing him just yet.
"Well, what have we here this time?" The Ashen and Azure Awaken of those toys called Divine Knights. As well as those Keyblade meddlers, but the rest of you..." Jedah rub his chin. "Hmm... I'm afraid i'm drawing a blank. I suppose that you are... less than important."
"Yeah, hardy har har. Like we care anything about you guys." Shez roll his eyes.
"All right Validar, where's Morgan?" Crow demand.
"Ah yes, I've forgotten the lover of my dear Granddaughter." Validar smirked. "If you're asking if she's here. I'm afraid I did not bring her here. I kept her quite busy."
"Tch..."
"I take it that's its you three that we're facing today?" Rean asked.
"Oh no, dear boy. Not us. We prepare a special guest just for you." Gharnef smirked.
"A special guest?" Brianna asked.
"Indeed. But unlike the monsters or Heartless before you. This one is something you're all familiar with." Validar smirked. "In fact, it's quite hungry for your flesh and bones."
Validar snap his finger, then a demonic roar was heard throughout the stadium as something large flew over them before it begin to make a landed behind the sorcerer trio. The creature behind them was a dragon. The dragon in question is something Rean, Crow and the others remember. Rean gasped as the Dragon lifted its head and let out a roar at them.
"What..?!" Aethe gasped.
"No way..." Rean whispter.
"Isn't that-!" Crow exclaimed.
Back in the Observatory...
"No... Impossible!" Emma shouts as Celine hiss.
"A dragon!?" Natsu exclaimed. "Man, I should have gone with them!"
"That isn't any ordinary dragon! It's the dark dragon- Zoro-Agruga!" Celine exclaimed.
"Wait, that cryptid we defeated back in the Dark Dragon Sanctuary?!" Machias exclaimed. "It's back?!"
"It shouldn't be! Grandmother prepares the spell to purify and defeat the dragon for good!" Emma exclaimed.
Back in the sanctuary.
"How did you manage to summon that cryptid again?!" Gaius asked
"How you ask? Come now, surely you all should notice the emblem on it's chest." Jedah said as they all look at the chest and they saw the Heartless Emblem.
"It's a Heartless!" Sora exclaimed.
"You turn the greatest of all cryptid into a Heartless?!" Crow exclaimed.
"That's right! Mwahahaha!" Gharnef laughed. "Lord Grima resurrected the greatest of all cryptids using the power of darkness and convert it into a heartless! Its powers you all faced before is far stronger than it originally was!"
"And it certainly remembers some of you who defeated it. And of course, the Divine Knights as well." Validar smirked. "It's so eager to see you again. So it will destroy you!"
"You son of a-!" Crow snarled.
"We face many monsters and cryptids before!" Rean snarl as he and the others got on their battle stance. "Just like them, they will fall and we will prevail!"
"Bwahahaha!" Jedah laughed. "Oh you think you can destroy him a second time? The last time you defeat it was with the help of the Divine Knights! Oh and don't even think about summoning those toys as well. Because right now, you won't be able to!"
"What are you talking about?!" Rean asked before notice the surrounding was darkness. "What?!"
"Go ahead, summon your Divine Knights!" Jedah demand.
'They're up to something... wait... can it be...' Crow gasped. "You little- you created a barrier didn't you?!"
"Oh? Already caught on? How disappointing." Gharnef muttered
"A barrier... you mean...!" Rean gasped.
Crow nodded. "Yeah. A barrier that can prevent us from summoning our Divine Knights!"
"And of course, we also seal the doors that will prevent you all from escaping. As well as interference from any of those Goddesses, and any means of entering this place until all of you.. and I mean all of you... escape here alive!" Validar let out a sadist smirk.
"You guys are monsters!" Mickey exclaimed.
"True monsters!" Paimon yelled
"It's laughable coming from a mouse! Now, destroy them!" Jedah order Zoro-Agruga as he spread its wings and flew over them and landed in front of them.

"Everyone! Are you okay?!" Palutena yelled.
"Ugh... we're fine..." Riku panted. "But this monster is really tough! It might be the most terrifying heartless in existence!"
"Well duh! It was a cryptid!" Viridi exclaimed.
"Oh lala~ Things are becoming very dire! It's almost like watching a beast finishing playing with it prey!"
"SHUT UP HADES!"
"Ngh... I'm not sure how much damage we'll be able to take if this goes further..." Aqua panted.
"I'm going to use Spirit Unfifcation knowing this is going to be difficult..." Rean muttered
"I'm afraid even Spirit Unification will be difficult in this fight! Everyone outside is trying to burst through that door. But the door won't budge!" Palutena exclaimed.
Outside the door entrance.
"Haaah!" Levi in his awaken formed use his strongest strike on the door but it failed. "Are you kidding me?!"
Haaah!" Laura yelled, unleashing a powerful slam, but the door won't budge. "Tch...!"
"Damn it! What kind of material is this door made off?!" Sara complained.
"Is Levi and Laura can't break it, then Rean and the others are toast!" Fie muttered.
"They has to be something we can do!" Alisa exclaimed.
"Even with the Keyblade wielders, I'm afraid it's going to be more difficult..." Gaius muttered. "Emma, Levi, you sense it too, right?"
"Yes. This door is imbued with powerful magic. Not only that, I sense incredible power separated within the door that is sync with the magic's defenses." Emma nodded
"Damn, those Old geezers really set us into a trap!" Celine muttered.
"Allow me." Ei pull out his sword from her chest and unleashed a powerful slash with an eye and an electrical emblem appeared and strike on the door, but nothing scratch it. "What?" Ei shocked.
"Order guide you!" Zhongli fire a large rocky meteor onto the door and exploded, however it still intact without a scratch. "Inconceivable..."
"This isn't good... This door is unlike any other. Grima must have use expensive materials to create this special door! I'm afraid we won't be able to get in!" Nahida exclaimed.
"She's right. There's also a barrier, preventing us from teleporting inside! I'm afraid this door is downright impossible..." Yae Miko nodded, looking distressed.
"No..." Levi look frightened. "Rean!"
Back inside...
Zoro-Agruga let out a roar at the group.
"Oh dear. Looks like that dragon is done playing around." Hades mused.
"The others and I can't break through the door! Is this hopeless?!" Palutena exclaimed.
"You got to be kidding..." Crow muttered as his thought of Morgan surface. "I can't give up... Not when Morgans needs me!"
"Yeah... don't give up everyone!" Rean yelled. "We can still make it through! Use the Arts, whatever crafts, magic and power to your fullest! Together, we'll defeat this monster once and for all!"
"Yeah!" Sora nodded. "You heard him, everyone! Let's do this!"
"Good grief... I didn't expect it would be this bad..." A voice sighed
(BGM ended)
"Wha-?!" Rean flinched
Suddenly a beam of light pierce through Zoro-Agruga's chest, causing it to roar in agony, shaking its body and head before it begin to collapse and a gigantic heart emerges from its disappearing body and disappeared later.
"Wha-?!" Aqua gasped.
"What... What happened?" Aether asked.
"Geez... I never thought they would pull something like this..." The voice said.
Rean turn his head and see the Mysterious Youth sitting on the ledge with his knee supporting his arm.
(Trails of Cold Steel IV ost - All-Knowing-One Ser- Version)
Rean gasped. "You're that guy from before!"
The Mysterious Youth let out a soft laugh with a smile. "Nice to see you guys are okay. Honestly, that was quite a dangerous situation. For them to go that far... It's waaaay overkill." He sighed.
The Mysterious Youth snap his finger and Rean and the others were glowing with a blue aura.
"What are you-" Rean paused as he felt his injuries are being healed. "Huh?"
"Whoa... I feel... completely healed." Mickey paused before turning to the Mysterious Youth. "Did... Did you save us?"
"Pretty much." The Mysterious Youth close his eyes as he smiled before he scooch off the ledge, disappeared, and reappeared behind Rean. "Glad to see you're up and Adam."
"Whoa!" Rean jump back.
The Mysterious Youth laughed. "Sorry, sorry!" he wave his hand. "I don't know why but I enjoy doing that to you."
"Okay, where did you come from?" Lea asked. "Also, who the heck are you?"
The mysterious Youth wrap his arms behind his neck. "Hmm... I suppose you can say... I was watching from the beginning."
"Say what?!"
The Mysterious Youth turn his head to the area around him. "This space we're in is different from the Phase Space you've all been through. Rather, it's an entirely different dimension whole. It's somewhat similar to the realm of darkness, however, unlike that one, this one is created from scratch. The dread fill the air, the blood moon, the sky red sky. It's like something out of a nightmare. My... Grima certainly kept himself busy. This place is suited for that Heartless cryptid dragon." He then sigh. "That poor thing. But at least he's dead." He turn to the others. "And the rest of you all right. Honestly, I'm quite worried."
"If you save us just now from something more terrifying as that heartless with one blow... you must be some powerful figure." Aqua muttered.
"I suppose so." The Mysterious Youth chuckled. 'Though that wasn't exactly my doing but another.' He cough to clear his throat. "On the plus side, you're all near Grima's doorstep. Well, I should get going." He turn his back and walk. "After all, your final battle with the Fell Dragon awaits."
"Wait! Who are you?" Rean called out as the Mysterious You stop and turn to him and gave him a wink before he disappeared. "He's gone." Then the Grand Star appear before them.
"That's the guy I remember back with that time with Azrael... but... seeing him up close... there's something different about him." Crow remark.
"You're right." Mickey nodded. "He appears to be young... however... I felt tremendous power within him."
"Yeah... who was that guy?" Riku was on his thinking pose. "He appears to be our age. But in his early twenties? Or younger?"
"Rean! Everyone!" Levi's voice called out as they turn and everyone rushed in.
"Levi! Everyone!" Rean exclaimed.
"Are you guys okay?! The door suddenly open and- huh?" Sara look around. "Wait, it's gone?"
"You all managed to defeat it?" Dimitri asked
"Not us exactly." Brianna shook her head.
"Pardon?" Dimitri asked as they begin to explain.
"That young man again?" Roselina place her finger to her chin, and unknowingly, Ei, Miko, Zhongli, Nahida and even Venti look at each other.
"That's right. He use some sort of beam of light on that heartless and it completely defeated him with one blow." Kairi nodded.
"A beam of light?" Arval rub his chin.
"I see. I'm so glad that all of you are okay at least." Kazuha then approaches Shez and hug him. "I'm... really glad you're okay."
"Oh Kazuha." Shez hug back and comforts his boyfriend. "Sorry that I made you worried."
"But who was that guy anyway?" Aether wondered
"Paimon wonders the same thing. But... if that guy is capable of defeating that legendary heartless... cryptid... thing... he must be more powerful... right?" Paimon asked.
"Right. The problem is that we don't know what exactly." Byleth said.
"Yeah, can we talk about this in the Observatory? This place gives me the creeps." Alisa looking around.
"Seriously. This dread in the air is making my fur rise up." Celine muttered
"Right. Palutena, can you take us out of here?" Roselina asked.
Palutena nodded and use her power as a Heavenly Light warp them to the Observatory.
(BGM ended)
"..." The voice hummed as it reveal to be the Mysterious Youth watching from the ledge. "Well, at least that's taken care of." He turn to his left. "Sorry that I had you take down that thing."
"Don't need for your concern." A new voice said.
Next to him was a young man who is in his early twenties. He has blue eyes and a pale complexion and eye-length, styled silver hair. A well-built body. He wears fingerless black gloves with a sky blue jacket with black long-sleeved shirt with a silver vest over it as well as dark long pants and brown shoes. In his hand is holding an ice-theme Keyblade.
"Though I admit. Seeing how Grima converted the greatest of all cryptids in Zemuria into a Heartless is quite dangerous. I'm surprised that he managed to control it." The Young man said.
"Well, Grima's Fell Dragon Powers are immense. It's what you expect from dragons. So has anything caught your attention?"
"Yes. A lot in fact. The Keyblade Master Aqua... that boy Ventus... Keyblade Master Mickey, That red hair girl, along with the red spiky hair man, that blonde girl who has the same weapon as that other girl. And finally... the one called Sora. I want to see what they're capable of."
"And there you go ahead with your drive." The Mysterious Youth sighed. "But the others don't pique your interest?"
"Actually they do-"
"So this was your doing." A voice said as a corridor of darkness appeared in Young Xehanort.
(Kingdom Hearts II HD 2.5 ost - Villains of all Sort)
"Oh?" The Young man turn around and see Young Xehanort. "I remember that face. Xehanort."
"Nice to see you again Xehanort." The Mysterious Youth turn to face him. "Or perhaps I should say... a pleasure to meet you for the first time... Young Xehanort. You certainly took your time." He then look with a smirk look. "Are the Seven Guardians of Light not your interest?"
Young Xehanort scoffed. "Don't get absurd. I felt some powerful form of darkness in this stadium. Hard to imagine that Grima turns that dead cryptid into a heartless. I can see he is a force to be reckoned with." He then shrug. "But I suppose I should thank you for saving them from that cryptid. It seems Grima and his underlings continue to fail in listening."
"I do hate it to break it to you, but Grima is someone who is beyond reasonable." The Mysterious Youth turn his back. "All he cares about is destroying humanity. Clearly, he has no interest in obeying your nor Xehanort. I'm sure even you know that."
"Quite. But it seems they'll make it in time to face Grima. However." Young Xehanort summon his Keyblade. "Why are you here?"
"Why you ask?" The Mysterious Youth asked with a musing tone. "Oh, I couldn't help but be curious. Don't worry. I won't get in the way of your plan with Kingdom Hearts. Besides, you'll forget this whole thing once you reach your defeat."
"You say it like it's going to happen."
"Did I?" The Mysterious Youth vanished before reappearing behind Young Xehanort. "If so then do ignore me." He then begin to walk around Young Xehanort. "So tell me Xehanort. Are you still bothered by Baldr's death?"
Young Xehanort begin to let out a low growl.
"Oh, right. My bad. I did not mean to bring up that sensitive topic." He casually wave his hand with a nervous smile before he look casual. "Why don't you return to the Graveyard?"
"I plan too." Young Xehanort said as his Keyblade disappeared, turn around and walk away as he disappear into the corridor of darkness.
"You have quite the history of people. Hard to believe Xehanort managed to bring his past self into this timeline." The Young man said. "What's your relationship with them?"
"Oh now you're curious?" The Mysterious Youth asked. "Well for the others, Organization members, we haven't met in person. But for Xehanort, Vanitas, and those other ones who were around before that certain "town" was destroyed... Let's just say "awhile" back." The Mysterious Youth then turns to the Blood Moon.
"A certain "town?" Now I have more questions about you." The Young man said to him. 'What is he?' He thought, causing the Mysterious Youth to let out a light giggle.
Meanwhile in Grima's Base...
"WHAT!? It can't be!" Validar eye widen as the cryptid is destroyed. "It should be impossible! HOW could they defeat it!?"
"SO THEY MANAGED TO DEFEAT IT." Grima mused. "IT SEEMS I HAVE TO GIVE THEM CREDIT. EVEN WITHOUT THEIR TOYS. VALIDAR, PREPARE THE DEFENSIVES! OUR FINAL BATTLE AWAITS."
"Y-Yes, Lord Grima!" Validar bow. 'How could those fools defeat that heartless... it should be impossible... unless... could there someone among their ranks be that strong? or... Did Organization XIII help them?'
I tried to be a little mysterious with a few characters and the story plot. Did that caught your interest? The Mysterious Youth age is between his early twenties along with the other young man with him. Curious to know who he is?
