This did not take a whole week this time! I think I might be getting back into the writing grove.

Thank you ObsidianUnknown66, keybladelight, Perran Onh, and The Keeper of Worlds for your feedback, thoughts, and questions. I also like to thank the readers along with those that favorited and/or followed the story.

Lea walked out of the Corridor of Darkness as the last trio exited out with him. Mickey, Donald, and Goofy looked at everyone in the room and the room itself. Sora looked at his friends as he noticed what had happened to the three of them. Instead of being just an anthropomorphic mouse, dog, and duck they each were surprisingly more human-like in proportions. Donald and Goofy almost jumped on Sora the moment they saw him. "Sora!"

Sora fell over when the both of them slammed into him with a hug. The Keyblade's Chosen groaned. Sure he knew that to them it had been months but for him, it had only been a few days. "Nice to see you both."

A few minutes later the thirteen Guardians of Light were together within what was once the Organization's Grey Area. Namine had informed them about all she could know about what has happened and then everyone turned to Sira. He had explained what happened to him after disappearing before their eyes. "So, the card that Luxord have you caused this?"

"I think it had a hand in it but I am not completely sure," It seemed that there could have been more to it. He was in the Final World, at just the edge of Kingdom Hearts, that had to have a hand in it.

Lea looked at the dark overcast out the window. Seeing how they still had no idea how they got here it almost looked like they were stuck here. "Hey, Riku have you managed to open a corridor to another world?"

Riku shook his head. It was something he had thought about doing but he could feel the unstable currents underlying the pathways off world. "I don't think that would be a good idea as, besides the force of the currents, I can also smell the Heartless moving through the corridors in massive numbers."

The redhead was getting as what Riku was talking about. Back when he was with the Organization they made it clear to not linger within the pathways for too long. Heartless used the very same pathways and back when the Heartless were invading the Realm of Light in force they would many times come into contact with them and had to fight through them. "How bad are we talking?"

"If I had to guess the whole world is being circled by whole armies worth of them at minimum," Getting a clear idea was hard as after a certain point the Darkness just gets so thick that the numbers can get masked. What was more confusing was why the corridors were so chaotic for the lack of a better term. 'The Realm of Light and In Between are stable and even heading into or near the Realm of Darkness is still somewhat stable.'

"Well, great we're stuck here for the time being it seems," Lea crossed his arms and looked at the room they were in. He was somewhat glad that they at least had some place to be while within this world. "Seeing how we're stuck here I guess we need to change how this place looks."

Everyone was in agreement with Lea on this. The rather lifeless feel of the Castle That Never Was likely worked for Xemnas and Xehanort. However, for them, this place just felt empty. "There a way to do that to the whole castle," Namine had felt it while she had been using her powers to locate the other Guardians. "There is one problem its located were the thrones used to be and only the Lord of the castle or the leader of our group can open the pathway to it."

That did sound about right to Roxas and Lea. Whenever Xemnas wanted to call them into a meeting it was he who allowed them to enter Where Nothing Gathers. Riku gave Namine a questioning look after hearing this. "Wait, weren't me Mickey, Donald and Goofy managed to get there before?"

"Yes, but Xehanort likely let you enter in order to tell Mickey about his plans hoping for you all to form the seven lights he needed," After hearing this both Riku and Mickey had to admit that it was exactly what had happened.

"Alright, so we just have to pick a leader and then we can change how this castle looks like with what Aqua did to the Land of Departure?" Sora was given a nod in confirmation from Namine. With that out of the way that just left the question on who should lead them.

Aqua couldn't believe it. She had been voted in as the leader of the Guardians of Light. On one hand, this did make sense because as far as she was aware she was the only one who knew how to alter something like the Castle That Never Was. Even so, it wasn't like she couldn't have taught whoever was elected about how to do it anyway. Regardless it seems that she had won. "I don't know what to say."

"Well, if I'm being honest the only two real choices are you and Mickey," Lea explained saying what nearly everyone was thinking. He crossed his arms in front of himself as he leaned on the wall. "Compared to my last boss I have to say this is a huge improvement."

Terra could only recall vague memories of his half Nobody but even he knew how badly Xemnas had acted forwards his subordinates. No doubt due to Xehanort's influence and desire to use the Organization as a means to create his thirteen Seekers of Darkness. Aqua turned her attention over to Namine. "Take me to where I need to go."

A few minutes later they all stood in front of a dead end wall. Namine motioned for Aqua to step forward to it. As she did it suddenly changed opening up as if the castle recognized her new position. Where Nothing Gathers, the former meeting place for the Organization, the place where Master Xehanort was reformed, and now the seat of the Guardians of Light. Each of the thirteen thrones lowered themselves waiting for their new owners to their place.

As soon as they all took their seat the thrones moved up as the thirteen of them looked at the platform in the center. Four symbols adore it. Mickey head, Sora's crown, The Nobody symbol, and the Mark of Mastery. Namine pulled out her Wayfinder and looked at everyone else. "We have to open the heart if the castle with our Wayfinders."

Be after another they each pulled them out. They each started to glow before flying out of their hands. Circling through the air they came to rest forming a heart shape within the air. On the platform below a Keyhole opened up revealing the heart of the Castle That Never Was. In a flash, each of the Keyblades wielders by those who could use them appeared in their hands. Pointing hers at the keyhole Stormfall was the first to shoot its light into the keyhole. The rest soon followed suit one after another until ten lights pointed into the keyhole. Donald, Goofy, and Namine each started to glow as well as the light moved from each of them to the nearest Keyblade wielder. With that, the keyhole was engulfed in blinding light as the sound of door unlocking, and then being locked, was heard echoing throughout the castle.

A pillar of light shot out from the Castle as its form was soon bathed in the glow breaking apart the overhanging shadows. When the light finally died down Aqua found herself within a room that almost reminded her of an actual throne room. She looked to her left and right seeing a town of smaller thrones each one seated almost like a U shaped table existed. To her right was Riku, Terra, Donald, Goofy, Lea, and Kairi. To her left was Mickey, Sora, Roxas, Ven, Xion, and Namine. Each one seated in that order.

Lea took a look at the walls seeing the four symbols from before edged in a repeating pattern. The Wayfinders slowed floated back to their owners. "Wow, I also can't believe that this is the Castle That Never Was."

"Do you have to keep calling it that?" Ven took his Wayfinder back as he looked at Lea. "I mean we completely changed it so shouldn't it deserve a new name?"

"Cor Cathedrali Basilica," The words left Aqua's mouth as she recalled an old tale about an ancient fortress of Keyblade wielders. It was one of her favorites books freeing up. Everyone looked at her as she realized she had actually said that "It means Cathedral of Hearts"

Sephiroth looked out from the cliff he was standing as a light wind blow over him. This world was nothing like Hollow Bastion. The place where he had been born, extracted from the heart alongside the light of Cloud. Strange he hadn't bothered to keep track of his "sister" until the time both him and Cloud had their final fight. Turning around he watched as a Corridor of Darkness formed. The Darkling walked out of it brushing dust off of its robe. "Well, I must admit that vampire could back up its claims."

"Do you think it was one of the, what was it called, players?" Sephiroth had been informed about the world he was currently in by the Heartless. Apparently, when he was reforming he might have gotten caught up in the tide of Heartless and ended up in this world. As for why he couldn't open a portal to Cloud it was thanks to just where they where located in creation.

The Darkling laughed at this. "No, I think it was one of the programs that came with them," The Heartless formed a ball of dark energy in its claws. "I left a little parting gift in the form of weakening the bonds put on their heart soon their Darkness will make itself known and with no idea how to deal with it…"

Sephiroth understood perfectly what would happen. The Darkness would overtake their heart and all that would be left would be a Heartless. "What about the body that you recovered?" He was speaking about the broken body that he had seen her work on. "Are you going to revive them?"

While the owner of the body did have a heart filled with it and said heart had gone to the Realm of Darkness making retrieval possible, the Darkling wasn't about to just revive the dead. Besides, there was no way to ensure their loyalty once they were brought back. "No, I am currently in the market for a temporary vessel and their body would do nicely."

Both of them looked out as they felt something. A wave of light had briefly erupted somewhere on the world. Appearing in a mist of Darkness a Fluttering answered the summons of its master. "Go see what that was," The Heartless disappeared for a moment before reappearing crushing into the ground as an unseen force deflected it from wherever it was heading. "That's just great."

First, he learns from Albedo that Shalltear had gone rogue, brought on by the effect of a World Item, and now Aura had informed him of her run-in with a pair of black creatures. The first was a mistake on his part assuming that no one in this world could have such things. His first thought was that it was the other Guild but apart of him suspected that might not be the case. In the few days after deciding to leave the Tomb to explore the world, he noticed a lot of similarities to the game he used to play. It stood to reason he was not the first one here.

There were a few missing Guilds and players which everyone just assumed had been deleted. Seeing how he somehow ended up here he wasn't so sure about it anymore. The run-in with the black creatures was what was more unsettling. One of them was able to ambush Aura even when she had tried to remain undetected. From what she had reported it wasn't a weakling and had an unknown the of magic that seemed stronger than it looked. The other creature, a tornado made from smaller ones had knocked both her and two of her pets around almost like it was nothing before disappearing. 'It appeared the moment the other one retreated which means they have some form of organization.'

If his passive didn't act up he would be panicking at this. The fact that they were organized and if neither of them was the leader he started to wonder how powerful they were. For all, he knew they could have been the one to use the World Item on Shalltear! 'I'm really am walking into a trap aren't I?'

Looking at the armors and items of his Guild he remembered what he had planned. If worse comes to worse he could get the floor guardians and use his friend's gear to help him. Sure, none of it prove sufficient then at the very least he'll finally get to see his mother again.

Sora and Roy stood out in the new look out of the newly named Cor Cathedrali Basilica. The castle was completely transformed. While it still floated in the air and was still shaped and made to be a fortress it was much more alive. Room for gardens existed, mural glasses windows, and less of a white and grey color scheme was just a few of the changes. In fact, it almost felt like a more fortress version of the Land of Departure. "You know this view is surprisingly beautiful."

"Yeah, but it can't beat our island," Riku was in agreement with him on that. Going on life-altering adventures to stop one man in one form or another from destroying the universe made one appreciate things they had. "Hey Riku, do you think we'll ever find our way home?"

He looked at Sora almost surprised by that question. "You should already know the answer," He pointed to Sora's heart. "Its always lead you to home in the end."

Sora placed his hand over his heart. The words that Yen Sid had always repeated echoed through his head. 'My your heart be your guiding key.' Right now it told him that they would find a way home. Until then it looked like they would make some new friends. "Thanks."

"Don't mention it," The two of them returned to looking out before Riku decided to ask a question. "So, you have you actually managed to keep all of your power this time around?"

Given the track record that Sora had with extreme metaphysical stress it was only right for Riku to ask. Especially given how hard he had abused the Power of Waking. Using it to bring the Guardians of Light back from the dead while rewriting time was pushing it and then chasing after Kairi's heart after she had died was seemingly too much for his body to take. "Yeah, I have no idea why this time was different."

A thought crossed Riku's mind after hearing this. "Do you think it was due to the X-blade?"

For a moment he wondered what Riku meant before realizing he was talking about the reforged X-blade. The Ultimate Weapon and the key to the True Kingdom Hearts. Xehanort had bequeathed it to him after having spent years setting everything up to make it. It was right there that Sora realized he finally had a proper Keyblade bequeathing ceremony and it was done by his greatest enemy of all people. Placing his hand on his heart he felt a faint connection to the legendary key. Even sealed with Kingdom Hearts it still called out to its master beyond what metaphysical barriers existed between them. Ready to be used by him. "I think your right."

Riku looked at Sora as all manner of questions popped into his head. "Do you think you can call it to you?"

Sora looked at his hand as for a brief moment he imagined it's handle within it. With it, he could probably get them home without any issue at all. "I sealed it along with Kingdom Hearts if I do risk reopening Kingdom Hearts."

Up within the heart of the central tower, she and Namine looked over the remodeled central computer. The Organizations central database had surprisingly not been emptied although such a thing could have been put on the fact that the Seekers of Darkness never had the need to do so. As such, they had what was basically all the research that Xemnas, Xehanort and the former members had made right in front of them. Right not they were using it for another purpose. "There the Gummiphones should be able to work."

Aqua took hers out and saw that everything looked to be in order. Having the means to communicate with each other would be a huge help for each of them. "I'm not getting contacts from Radiant Garden."

"I'm sorry I don't know what else to do," She was still rather new to computers. Actually, she might be the only one besides Mickey and Lea who could work this thing.

A sigh escaped Aqua's mouth. "I should have expected as much," Opening the Lanes Between had been a bust as well. This just meant they were going to need to find some way to create a Gummiship. Maybe she just needed some fresh air to think of a plan. "Do you mind if I could have a few Corridor of Darkness cards so I can go for a walk?"

To think that all this time she had fallen into Lord Ainz plan. Her mana was gone and now here she was struggling against him as he used the weapons of his fellow Supreme Beings. Shalltear still didn't know why she wanted to kill him but right now she didn't care as she thrashed about with her weapon. 'How can I ever hope to win!'

In her desperation, she unknowingly broke through the sealing chains of YGGDRASIL. As soon as the formerly digital seals broke her heart pulsed as the Darkness long caged finally had somewhere to go. "This…" Ainz noticed that something felt off about this situation. A dark aura started to surround Shalltear who immediately felt the power. "This is amazing!"

A surge of Darkness pulse out of her being catching Ainz by surprise. He had made sure that Shalltear MP had been drained completely. "What's going on Shalltear!"

Shalltear let out a yell as the damage to her body was in a rapid rate healed by whatever power that this was. She clenched her newly rebound arm. The Darkness gathered within it as a tint of gold entered into her eyes. "To be honest I haven't got a clue what this is," A smirk formed on her face as she could tell that this was something even he, one the Supreme Beings didn't know. "I'm not about to ask questions."

'Ok, new plan,' Ainz blocked a thrust from her lance. 'This can't last for long I got to…' Another lance made from condensed Darkness slammed into his chest knocking him out of his thoughts. 'She shouldn't have any MP left!'

Unless whatever had happened not only healed her but replenished her MP. Judging by the fact he was now having to guard against two attacks at the same time now, one of which was made from what he assumed was whatever this energy was, it was probably safe to assume that might be the case. Knocking away the next two strikes he began to consider his options.

While he tried to figure out a way to salvage his plan or make a much needed change, Shalltear was wanting more of whatever this power was. Like a drug Darkness could become addictive especially to young hearts or those unable to grasp the full problems of the power. Her heart burned with the Darkness causing what Light within it to scream out but was silence.

"Give into the Darkness," Something of a voice echoed faintly within the back of Shalltear's mind. Shalltear should be wondering where this voice was coming from but she was submerged into the shadows to care. "Let its power surge through your very being!"

Darkness continued to leak out of Shalltear's form gathering around her body. Ainz had made note that whatever this ability was it was seemingly getting stronger with each passing second. Shalltear was letting this newfound energy get to her head. It was something Ainz hadn't seen. Something he hadn't planned for. Without caring or knowing of the consequences she gave further into the power.

Her eyes widened as in that moment Darkness surged from her body unchecked. Unknown to her she had just hit the tipping point and now her Heart belonged to the Darkness. It was at this moment that her sanity had returned but sadly for her, it was too late. "W-what hap-happening!"

Everything went dark as she felt her sense of self start to fall. Unknown to her the effects of the Darkness was too much for her heart. A laugh echoed through the void of Darkness that her identity found itself in. "Your heart belongs to the Darkness," A claws hand appeared in her vision and touched the eyelids of her self identity. "Sleep within your heart."

One final blast of Darkness came from her body. Ainz covered his eyes as the energy past by him. When it was over a ball of dark mist hung within the air before it broke apart like a cocoon. Two dark jagged feathered wings flapped as two arms with elongated red claws banged over from what looked like a mockery of Shalltear armor chest plate. Said armor broke apart near the legs into some kind of jagged mess just below the waist. Its head was that of Shalltear true form but with red glowing hair and gold lifeless eyes staring down at him.

The newly born Twisted Valkyrie, Shalltear's Heartless, let out a primal hiss as it looked at the being it once served. Ainz and the rest of the onlookers of Nazarick looked at the creature with complete and total shock. 'WHAT THE HELL JUST HAPPENED!'

Immediately Ainz passive activated to calm his emotions. Even with it he still couldn't believe what he was seeing. Shalltear had turned into one of the black creatures. Twisted Valkyrie felt a presence call to it nearby. The newly born Heartless instinctive recognized the nearby leader of its kind. Turning down as Ainz it knew what they wanted. Darkness gathered around it as it hissed at the Overlord. Two balls of Darkness gathered in its claws as the Heartless slammed them into the ground. A wave of dark mist covered the area and almost blinded Ainz's sight.

He raised his weapon to defend against a counter attack but instead of a slash with its claws, Twisted Valkyrie lunged forward and grabbed him. Ainz was brought up to its face and looked straight into its dead yellow eyes. At that moment he knew that this was no longer anything there. "Shalltear what have you become?"

It took off into the air and then throw him into the ground kicking up dust. Ainz cursed under this breath at this. Whatever had happened to her hadn't decreased her power. He almost wondered if she was even stronger now. Two dark javelins formed floating above its claws.

The two were tossed aimed straight for Ainz heart. Ainz quickly summoned the shield he was using from before when a wisp of energy shot out and exploded in front of him. Instead of hitting the shield the two dark javelins hit a semi-translucent honeycomb barrier. Twisted Valkyrie's eyes turned red as it looked at the interloper.

Stormfall was brought back to her side as Aqua stares down the Heartless in front of her. She had just wanted to go for a walk. Her eyes narrowed as the Heartless hissed at her. Darkness surged from it as it tried to intimate the Sapphire Sorceress. After having spent over a decade with the Realm of Darkness nothing about it intimated Aqua one bit. "Alright then."

I'll be honest when I was planning this story out I had always wondered on who to pick for the leader of the Guardians of Light. Aqua was my personal choice because as Lea stated it was either between her or Mickey on who would make a logical choice. Anyway, you can all guess What's going to happen next chapter but what would be the aftermath of it? I'll leave that to your thoughts.

Anyway, cya all next time. May your heart be your guiding key.
