Preliminary Author's Note: This is an AU/Crossover with the anime Tsubasa Reservoir Chronicles (TRC), and for the sake of presenting this story, its main characters are introduced in this prologue. For a better reading experience, and if you haven't seen TRC, I'm sharing with you the first episode of the anime, where its plot and characters are pretty much laid out beautifully. It is in Japanese but English subbed (I'm sorry but I couldn't find it complete and dubbed in English on YT).

The episode is divided in three parts (ff removed the first part of the link, so please copy them in your browser after the youtube address):

Part 1: /watch?v=01R9J5jhtR4&list=PLB3C90D9359352834&index=1

Part 2: /watch?v=w6aGMxO4u4o&list=PLB3C90D9359352834&index=2

Part 3: /watch?v=34UOqZrbwwg&list=PLB3C90D9359352834&index=3

I also have to clarify that the TRC characters will appear in the two following chapters as well in order to explain where this story is going, but I promise that after that the fic will focus entirely on CS, there will be magical creatures here and there but they will be explained through Killian's and Emma's eyes so as not to confuse you.

Thank you for reading and I hope you enjoy the fic.

Prologue

Killian Jones was not a man known for his patience or self-restraint. He had arrived to Storybrooke almost a month ago, a good amount of things had happened since then, and yet none of them have had to do with his revenge on that damned Crocodile, the mockery of a man. Well, that was not entirely true, there was the little matter of his Crocodile going into his ship on the very next day after his arrival, hitting Killian with his cane, after learning the bastard had managed to bring magic into this realm too, and that he was still powerful as he had been back in Fairytale Land. That served as a great problem to the pirate.

He had just been prepared to end the Crocodile's life too, he had almost run him through with his sword; but then his little Swan –no, not his Swan, what was he thinking?– had appeared next to him and stopped him with the slightest effort on her part. He couldn't argue with the emotions that stirred in him when he saw her. She said she was the Sheriff in this land, and by that also the Law, and that she wouldn't allow him to kill the Crocodile so easily. She had already seen the cane-hitting little stunt though, and she also addressed the demon and told him he couldn't harm Killian either. She had threatened them with the idea of sending them both to jail if they didn't comply. "So, you rather like to see me in chains, right love?" he had said to her flirtatiously. He still didn't understand why was he so eager to make her want him—to elicit some sort of response from her. She had scoffed at him, facing away from him, instead of answering.

And things had only gone downhill from there. He hadn't been able to end the ticking time left of life in his Crocodile, and he had been so damn distracted by her. He had been stalking her –no, not stalking, just looking after her, he ensured himself,– the whole damn time, he was so relieved when the Queen and the Crocodile had managed to restrain Cora and put her in some sort of deep slumber. He had even gotten to know Emma's little lad, he had the same fiery spirit as his mother; yet he was even MORE perceptive than her. He had known right away he was not only the notorious Captain Hook but also Peter Pan, something he hadn't shared with Emma yet- let alone anyone else. It was his past after all, he did not see the point in sharing. He had kept his distance because he could see she still didn't trust him, and he was damned if he was any closer to admitting he really cared for her. The beautiful and fiery Swan. Curse her locks of blonde hair and air of authority, despite having caught her glances of uncertainty of IF she were to act on her duties, he wondered, would she be able to live up to them?

Emma… Now Killian stood at the docks where his beloved ship was supposed to be waiting for him in the calm waters. But it was gone. He couldn't understand it at first, and then it hit him: that damn Crocodile had somehow sent it away. His ship was his anchor –no pun intended– to his past, to Milah and all the adventures he'd had with her, including his travels in Neverland... He just couldn't believe it, but he also knew there was no way for anyone to simply take the Jolly Roger out to Sea, since she only responded to HIM. He knew what he must do, he needed to go see Emma, his Swan –no, not his, dammit!– and report his ship being stolen. She was the Law on this land, after all.

A small smile crept into Killian Jones's lips. Yes, he wasn't an impatient or restrained man. But now he had the perfect opportunity to have a very long talk with Emma. And he was going to get her to confess just why she had left him up on that Beanstalk. How dare she left him all alone up there, it was unfair to him. Oh, he would have a VERY long talk with her. And he just couldn't wait.

A boy called Syaoran resurfaced from the deep and freezing waters at a dock in the strange world they had landed in this time. He could see Kurogane getting out, he was extremely angry and cursing Mokona for always making them land in the worst possible way imaginable. Yet Fay seemed to almost glide out of the water, his eternal smile plastered on his face. Sakura-chan was at his side and he quickly closed the gap between them with frantic strokes.

"Are you okay, Sakura-chan?" Syaoran asked, with concern clearly written on his face.

"Hai Syaoran-kun, I am okay." a beautiful smile appeared on her face and his heart skipped a beat.

Sakura… She still couldn't remember who he was to her once before, but since they had found so many of her feathers, which had memories buried within them, she had regained that little spark he so loved, and her boldness too. He was so relieved she was okay and unharmed. The little rabbit shaped one, Mokona, was happily chirping and making other odd sounds at the edge of the dock, where Fay was restraining Kurogane who had tried to strike him with his sword.

"So, this is an interesting world. I can sense there's a wonderful sort of magic here, although there's evil magic somewhere too. Seems we have woke her." Fay said, with his usual unexplained confidence.

"Well, I'm glad no one saw us appear from the water anyway. But I really need a towel to dry off, that water was freaking icy." said Kurogane, maintaining his glare towards Mokona.

"We have to find out what sort of place we've arrived at and where Sakura's feather is this time." Syaoran started to walk away from the docks and further into the town, with Sakura following closely on his heels.

"I think I know where the feather is…" she said, and the three of them turned around to look at her.

"Sakura-chan is really becoming stronger with each feather we find. Not even Mokona has alerted us towards the feather yet." said the wise Fay-san with a tender smile towards Sakura.

"Well, then let's get the heck out of here and search for the feather. I really want to get out of here as fast as possible, I sense evil lurking" remarked Kurogane, searching frantically for the source of the evil he and Fay-san had sensed.

"Who are you and what are you doing here?" A female voice, kind yet full of strength, said behind them. The four of them turned to look at her and saw a gorgeous dark haired woman with fire in her eyes and red streaks of color in her long hair that spilled over her shoulders, wearing a red cloak, and Syaoran recognized she was not an ordinary woman: she was also a wolf. Much like the spirits from the Hanshin Republic where he had been guarded by a wolf-like figure, a kudan it was called. Perhaps this instance made it recognizable, that she too had a likeness of a canine.

"We better be careful, she is a wolf." Syaoran said to his party, only loud enough for them to hear.

"Yes, I sensed that too, Syaoran-kun, but I also feel she is trustworthy and won't attack us, as she has not yet done anything to make me think otherwise. I'll deal with her" replied Fay.

"Forgive us, we've come from far away and did not have the most fortunate of landings" Fay explained using his normal volume of voice again, signaling to their wet clothes. "Perhaps you would be so kind as to show us a place where we can dry ourselves and get warm."

It was a young woman named Ruby that had noticed their arrival when she was strolling around the docks this morning: a weird-looking vortex, that could only be a portal, opened up in the water and four strange people and one even stranger animal appeared through it abruptly.

They were wearing very peculiar clothes, each one in a different outfit better fitted for a completley different weather. Although they spoke in English they used odd terms and what she assumed to be pet names, like adding the suffix '-chan' to the girl's name any time they addressed her; if she had to guess she'd say they sounded like Japanese words. The only girl among them was quite beautiful, with short light brown hair and bright green eyes, although she couldn't have been older than eighteen. She was wearing an outfit that reminded her a little of a belly dancer's, much like Jasmine's from Aladdin, a girl from Henry's fairy tale book; it was white and purple with little coins in the sleeves and a long white skirt with a broad waistband that also had small coins.

There was a younger boy with dark brown hair and brown eyes that she could only guess was her boyfriend, as he was really protective of her. He was dressed in green and strange coat and brown pants, with a brown cloak and goggles placed atop his head.

There was also an extremely tall and handsome man all dressed in black, with a black cloak and a big katana in his right hand. He had a tough look and seemed very annoyed. At his side,was a slightly less taller guy with extremely clear pale skin and blonde hair; who seemed to always be smiling whether it was from his grin or his ice blue eyes. He was wearing something akin to a medical gown with blue stripes, with dark blue pants and boots on underneath.

Ruby was startled by a little white ball that seemed like sort of a fluffy and strange white bunny that started chirping and making happy sounds, especially when it jumped into her arms.

"You'll have to tell me your whole story first. Who are you—really? You used magic to get here, I saw the portal closing up after you appeared. Also, what is this thing and why is it cuddling me?" said Ruby, while she squashed the little creature lightly in her hands, testing it's patience with her, like dog to a mouse that was not supposed to be where it was found.

The second tallest man answered first.

"My name is Fay, I also come from a magical world, and they are Princess Sakura-chan, Syaoran-kun and this big scary fellow over here is Kuro-sama" Kurogane glared and lunged after him, but was stopped by Syaoran– "That little cutie in your arms is Mokona, and I think he has taken a liking to you." Fay said with a flashing smile. "We travel between dimensions in search for something precious to our Princess." He gestured a long arm towards the girl decorated in gold coins.

She didn't know what to ask first, so she started with the most shocking statement she had heard so far.

"You said you travel between dimensions? How is that even possible?"

"We have the help of the Dimension Witch, Yuuko, who first sent from her shop, then with little Moko-chan's help, who sends us through dimensions and worlds, in search of Sakura's enchanted feathers."

"Do you think it's wise for you to tell her everything? We don't know if she can be trusted! We can't endanger Sakura-chan!" Syaoran had pulled Fay aside and said, so only he could hear.

"Don't worry, Syaoran-kun. As I told you, I know she can be trusted, I only sensed a very evil and powerful magic upon our arrival elsewhere in this world, but she has nothing but good in her. I also know we can trust her, as does Mokona."

Mokona was still happily resting in the wolf-girl's arms, and had started to make the purring sound that signaled he was happy. Syaoran could even tell that Kurogane had relaxed a little when he saw Mokona jumping to the girl's arms.

"Okay, carry on, we need to know where we are too." Syaoran said with resignation.

"Her… feathers? What does that mean?" The girl asked, confusion in her voice.

"Her soul, and memories, and the source of her magic; in the physical form of feathers. An evil Wizard scattered them through the dimensions and we need to find them so she can be whole again, regain her magic and her memories." Fay-san answered.

"Wow, don't I know enough about evil Wizards. Well, then welcome to Storybrooke. We have been victims of an evil curse here too; we're originally from another world called The Enchanted Forest. My name is Ruby, although you may call me by my more truthful name: Red. Come this way, we'll go to Granny's to get all of you out of those wet clothes and into something dry. Wouldn't be very good for us to let guests get sick!"

They followed the wolf-girl, not knowing that a figure lurked in the shadows and had heard everything they had said. Cora emerged from the shadows with a big smile on her face.

"Well, well, well; so these strangers are the ones who broke the silly magic my daughter and Rumpelstiltskin used to restrain me. I'm so grateful though, since now I've learned a way to end the Swan princess as a gift to my daughter. It would also have a bonus in seeing Hook suffer, he betrayed me after all; he still doesn't accept he has fallen for her, foolish boy! That Princess Sakura has the same kind of magic as the daughter of Snow White, I could sense it when she surfaced from the water. And that means I can do the same thing to the Savior, I can't take her heart but I will clip her wings. But I have to bid my time, these strangers need to leave before I make my move. It's a good thing I AM a patient woman…"

A/N: So please let me know what do you think of the prologue, I really look forward to your input! There will be angst but rest assured that I only believe on happy endings.

Many thanks to my lovely beta, Sandra Lynn, you are wonderful!

Thanks for reading!
