The day following Roxas returning to the Gummi Ship, and telling everyone that he was done with his time in Twilight Town, was followed by a surge of activity as everyone got ready to do their own tasks for the next stage of their war against the Organization and Master Xehanort's plans. Sombra was splitting them into groups, the force that would be heading to all of the worlds and directly dealing with the Organization's plans, a group that would be staying in the Gummi Ship to train and prepare themselves for the future, and a group that would be secretly watching the Organization's movements. Axel, Xion, Riku, and Larxene would be keeping an eye on what Xemnas was having the others do, one pair of eyes on the inside and three on the outside as Xion didn't want to return, and Marluxia was in charge of all four of them, an extra pair of eyes looking over a larger area in a sense. Aqua and Ventus were to stay in the Gummi Ship and either train with Kairi or help Ansem the Wise with his research, as he was working hard to find more clues about Terra, since Sombra was sure that there was a way to free him without having to deal with Xemnas, and while Kairi wanted to help she knew that she had to train to not be a hindrance.
With that in mind the group heading out into the worlds consisted of Sombra, Fluttershy, Radiant, Seras, Sora, Donald, and Goofy, though Sombra didn't give Mickey any roles because it was best if he was a free card that would keep the rest of the Organization on their toes, guessing at where their enemies were and what they might be doing.
Mickey also told them that there was someone they should check in with, the man who trained him in the art of using a Keyblade and using magic, because it was about time for them to make him aware of the situation they were in and see if he had anything to say about their war against Master Xehanort. At the same time there was another reason for visiting the King's mentor, he had three good fairies that would be able to quickly whip up some new clothes for them, as Sora and the pony girls had grown over the year they had been adventuring, so their original clothing was starting to look like they might outgrow them in the near future. It meant they could kill two birds with one stone, tell their last ally about the information they had discovered so far while also getting an update to their clothes, even though Sombra knew Radiant was eager to see if the clothing was as Mickey said or not. Mickey also mentioned that finding the tower could be hard to do, in fact there was usually a train that allowed one to find where it was located, though considering who they were he had a feeling that his master would allow them to find it easily.
Fortunately he had a direction to point them in before heading off to do his own thing, where Sora eventually found tracks in space that brought him to a small world, a single crooked golden-brown tower on a mountaintop, or the floating peak of a mountain, and standing at the door was a large chubby figure that had pried the door open a little, causing Sora and the others of the ground group to teleport down to the surface without delay.
"Excuse me, but, do you need help with something?" Fluttershy asked, though after regaining her form and training with both Aqua and Seras, to regain her skills and abilities, she was ready to tackle whatever the future held in store for them, though while she knew this person might be evil, he did seem to be lurking around the tower like a stalker, she wanted to be sure before they did anything.
"Nope, just waiting for my lackeys to return. I sent some inside this here tower, to find the master of it and turn him into a Heartless, as I hear he's a powerful sorcerer!" the figure stated, where Sombra immediately assumed he was an imbecile, as no evil person would be so foolish to tell random strangers their evil plan, not unless they intentionally wanted to lure the enemy into a trap, and right now this person, who Donald and Goofy seemed to recognize, was far lower than Maleficent had been in Sombra's mind, "You see, I want to make him into my bodyguard while I make my rounds in the various worlds that are out there, as I'm building an army to give to Maleficent so she can conquer everything, so having such a powerful Heartless with me will make things easier!"
"Sorry to tell you, but she's already been taken out." Sombra said, where the figure turned around and looked at them for a moment, where he came face to face with Donald and Goofy with a look of surprise on his face, something that made her a little eager to learn more about the figure that was supposedly on Maleficent's side, "You know him?"
"Yeah, Pete's been causing trouble for ages... both King Mickey and Queen Minnie have imprisoned him multiple times, trying to stop him from continuing down his path, but he's been very stubborn." Goofy replied, once more reminding Sora that he was smarter than he appeared, which was a good thing that they used against their enemies, as no one seemed to think that a Captain of the Guard could be smart, "Supposedly he was locked away in a different dimension or a special prison, but somehow got out... guess we can say Maleficent freed him."
"You're lying. There's no way you pipsqueaks did in Maleficent." Pete replied, showing them that he thought that the one who saved him was actually far more than what he thought she was, no doubt due to her springing him from the prison he had been locked in the last time the rulers of his world had been annoyed with his dark antics.
"Well, Sombra crushed her magic and then crushed her dragon form... word to the wise, don't make her angry." Donald said, because he knew that Sombra's power when she was blinded by rage had been more than enough to destroy the dark witch before she could do anything to her or the rest of the group, to the point where Maleficent's dragon form did nothing to slow the figure beside him down, plus he knew of her rage firsthand, hence why he wasn't in the mood to make her angry again.
Pete growled, stomped on the ground, and charged at them with his fist at the ready, where Sombra raised her right hand for a moment and caught the attack by stopping it with her pointer finger, only for her to grab Pete's head and toss him off into the distance, banishing him from this world and likely sending him back to his ship. With that done they entered the tower and found that it was just an entry level with a spiraling staircase heading up to the peak, though Sombra could see that there were a few doors for them to walk through, no doubt to skip segments of the structure. This time around Fluttershy stepped forward as she summoned her Keyblade, showing them that she had definitely matured after what had happened to her, giving her more resolve and courage than before, and Sombra was sure that spending time with her other half had something to do with the slight change in her as well. The enemies that ended up getting in their way were the Shadows and a couple of Soldiers, all weaker than the ones Sombra's allies had taken out when they faced the army of Heartless, so it was easy for Fluttershy to deal with them, wielding her Keyblade and her magic to take them out, while at the same time Sombra snatched the few freed hearts before they disappeared.
With such pitiful enemies in their way it didn't take them long to reach the peak of the tower, where they found an older man, a sorcerer who had incredible power inside his body, sitting in the chair that was across from where the door they entered through was located, who wore a blue robe and a blue magic hat, while having a long gray beard.
"Master Yen Sid." Donald and Goofy said, where they respectively bowed to the figure that was in front of them, which was followed by most of the group, save for Sombra, though no one was going to tell her otherwise, since they knew that she far outranked them in physical and magical ability.
"Donald, Goofy, it would seem that Mickey was right: you accomplished your mission and more." the sorcerer, Yen Sid as the pair called him, said, where he waved his hand for a moment and the room transformed, his desk forming into a table with drinks and snacks appearing all over it, showing them that he wanted to be a good host to them, "His message also told me that we had much to discuss, and that it was better delivered in person. Tell me, what have you discovered about the Organization and it's leader?"
"Plenty, actually." Sombra replied, where she and the others took their seats, some even helping themselves to the drinks and snacks that had been provided to them, though she knew that Yen Sid would be in for the conversation of his life, or at least an exciting one since he might not know much about the ongoing situation.
Sombra explained everything they had discovered so far to Yen Sid, telling him about how Maleficent had been planning on using the Princesses of Heart to open the 'Final Keyhole', how she had been used by Seeker Ansem, a Heartless that was made from Terra's body and Master Xehanort's heart. With them having recovered both Aqua and Ventus, something that made the sorcerer spit out his drink in surprise when he heard it, they now knew more about Master Xehanort's plan, one that both his Heartless and his Nobody were trying to complete by using their own means, the creation of the 'true' or 'pure' Kingdom Hearts. It was what they had dealt with back when they were facing Maleficent's forces, they sealed both the Door to Darkness and the Kingdom Hearts of Worlds that had been created by the Heartless consuming worlds, hence why Sombra was referring to it like that, while at the same time Xemnas, the Nobody, was building a Kingdom Hearts of Hearts. Both wanted power and knowledge, that seemed to be their excuse for wanting to form the powerful entity in the first place, and both Seeker Ansem and Xemnas had their own methods to bring about that reality, which they covered with ease, since Yen Sid was able to connect the dots based on the names of the two artificial Kingdom Hearts.
While they talked a trio of fairies, ladies who floated around and wore three different colored dresses, one red, one blue, and one green, came out and took the measurements of Sora, Fluttershy, Sombra, and Radiant, so they knew what to do when it came time to fix their clothing, but Sombra was focused on other topics.
She also corrected Yen Sid's opinion on Nobodies, as he claimed that they didn't have hearts and shouldn't exist, where Sombra told him that such a thought was horribly incorrect, as Nobodies could, in fact, use their own experiences to form their own hearts and become their own person. In fact there were several such individuals among her 'forces', as Yen Sid preferred to call everyone else for the sake of not getting things confused, as there was Sora and Roxas, Fluttershy and Seras, Kairi and Namine, and so on, all of whom had figured out how to form their own hearts. In addition to that there was Xion, someone created from nothing more than a bit of memory, who figured out how to make her own heart while also becoming her own person, to the point that she was able to manifest her own unique Keyblade, something that came as a surprise to Yen Sid. That brought Sombra to the crux of their ongoing mission, dealing with the remaining members of the Organization while at the same time trying to free Xemnas, at least, from the dark hold of Master Xehanort, to make him truly become his own person and break whatever dark plans Xehanort was working towards.
Yen Sid wondered why Sombra was willing to risk everyone on one individual, but decided that it was best to not question her decision, as he could sense the staggering power hidden deep within her body, even depths she was working towards at this very moment, and felt that fighting her, even with words, would be a bad idea.
Once he had a better idea of what they were going to do, even if it sounded weird to him, Yen Sid had them take turns in the chamber of the good fairies, where Sombra found that her clothing, along with Radiant's and Fluttershy's, were simply sized up to fit their older bodies and patched up to look brand new. Sora was the only one who got new clothing, as they found that his shorts became black and were chap styled with a blue inside, with a pair of yellow belts linked to a black belt on his waist, which were also connected to two red pockets for him to store stuff in. He was also wearing a new blue shirt that was under a black hooded jacket, the latter also having what appeared to be shoulder guards, and his shoes had a facelift as well, shifting to match his growing body and becoming more black than yellow. There was also something very special about this new outfit, as the fairies explained, as he could call on the power of Donald or Goofy and empower himself with new forms, similar to Riku's amulet, and his first 'form', the 'Valor Form', utilized Goofy's power while granting Sora a second Keyblade, a magical looking one.
"Might I suggest heading to Hollow Bastion, to start off this journey? It has changed since your last visit." Yen Sid said, as he knew that Sombra had a plan and he really didn't want to disrupt whatever she had in mind, rather he was hoping that this would aid her and her friends in traversing the worlds on their new quest.
Sombra nodded as their visit to the tower came to an end, allowing them to warp back to the Gummi Ship, though as Sora got underway she found that a raven flew into the chamber that had the fairies, with a familiar dark robe, and Maleficent was revived in no time, a figure who fled before she was discovered. Such a thing caused her to grin for a moment, as she understood what had happened, Maleficent had hid her essence, her heart in some form, inside the robe and tasked the raven with delivering the article to someone whose memory could revive her. If that was the case, and people could be brought back in such a manner, Sombra had to wonder if she could use Terra's heart, plus the memories of Ventus and Aqua, and something that held his essence or part of him, like his lost armor according to Aqua. She could bring Terra, the third and final lost Keyblade wielder, back from the brink and really screw over Master Xehanort's plans, something that caused her smile to widen as the others got underway for their departure.
She had a feeling that this adventure was going to be more interesting than she had previously assumed, especially with Maleficent accidentally revealing something to her, and it made her that much more interested in what the future held for her and the rest of her friends.
