So, this is my first fanfic here :D This was sort of a prompt. I saw this picture in deviantArt and was quite interested in making a story out of it and the artist, ewelock, encouraged me to do so. So, this will be multiple chapter (don't know yet how many), totally Bagginshield and Swan Princess!AU. Hope you'll enjoy.

Chapter one

Once upon a time there was a beautiful kingdom called the Shire. It was ruled by much loved King Bungo and Queen Belladonna. They were however troubled, for they had no child to inherit the realm. Belladonna became even more distressed as Bungo passed away after a long illness. She was lucky, though, as she realized shortly after Bungo's funeral that she was with child. Some months later a healthy boy was born and Belladonna named him Bilbo.

The kings and queens from all over Middle-Earth gathered in the Shire to the castle of Bag End to pay their respects to Bungo and greet little Bilbo. Among them was Thrain, the King under the Mountain, the mightiest of the dwarf lords, and his three children, Thorin, Frerin and Dís. As Thrain saw the new heir of the Shire, he went to Belladonna with a suggestion. Their children could see each other every summer and if and when Thorin and Bilbo were to fall in love, they could unite the kingdoms of the Shire and Erebor forever. Belladonna considered for a moment and agreed. They had been planning the union for years but there hadn't been a chance for it until now.

Both realms were happy, but the happiness was short-lived. An evil wizard named Smaug marched to Erebor with his army of orcs and tried to take over the power by using Dark Arts. Thrain and his elderly father Thror marched against them and won, but Thror was killed by Smaug's right hand, the Pale Orc. Azog beheaded Thror and drew Thrain mad with rage. In his anger he managed to drive off the orcs and strip Smaug off his powers. He would've most likely also killed him, but his friend, the wizard Gandalf the Grey, asked him to show mercy. And thus Thrain only sent Smaug into exile. The powerless Smaug swore his vengeance on Thrain and his heir one day, and many were afraid that Thrain had been too lenient. But as the years passed the threat was forgotten and everyone's hopes were aimed at the summer when Bilbo and Thorin would meet.

"Mum, do I have to?"

"Bilbo, we have discussed this many times now", Belladonna sighed as she combed Bilbo's curly hair. "You and Thorin are the heirs of the realms. Besides, how do you know you won't become his friend if you've never met him?"

Bilbo scowled at his mother. "He's a dwarf! A dwarf, Mum! You know they're not nice! All they care about is their gold and jewels. I know that well enough and so should you."

Belladonna sighed again. She didn't know to whom Bilbo had listened to about the matter of dwarfs (but she guessed it was the Sackville-Bagginses) to be this prejudiced. She finished her son's hair and said, "Look, Thrain is an old friend of mine, so make sure you behave around him. And you won't be alone. Thrain will bring his two other children, Frerin and Dís, as well."

"But still..."

"Oh, you are just as stubborn as your father. Bilbo, promise me that you'll at least try to get along with Thorin."

Bilbo pouted a little, but promised to try. Belladonna ran his fingers in his curls and smiled. Bilbo was only a child, but he had his father's bearing. Then Hamfast, their head gardener and butler, knocked the door, came in and announced that Thrain and his company were to arrive in ten minutes' time. Belladonna got up on her feet and grabbed Bilbo's hand. She smiled at her nervous son encouragingly and walked into the garden after Hamfast.

Thrain, his children, and the rest of their company did arrive in ten minutes. Bilbo felt scared. Thrain looked good-natured enough, but the dwarf lad riding beside him – Thorin, Bilbo assumed – was clearly frowning at his father, looking both bored and angry. Thrain did not seem to notice this for he had his eyes on Belladonna. His two other children, Frerin and Dís, rode on the same pony behind their father and elder brother.

"Hello, dear Belladonna", Thrain greeted and dismounted his pony. "You look as lovely as ever."

"And you are the worst sort of a flatterer, Thrain", Belladonna laughed. "Welcome to Bag End once again."

"Your son has grown a lot", Thrain commented. "He takes after his father, I see."

Bilbo bowed shortly and then hid behind his mother. Belladonna simply explained that he was awfully shy when he had to meet new people. Thorin snorted and earned a smack to the back of his head.

"We are guests, Thorin", Thrain scolded. "I expect you to behave like my heir to the throne should. And if you ever so much as mock Bilbo again, I shall see if you're not too old for spending a whole afternoon learning all the dialects there are for Khuzdul. That should teach you some manners."

"Father!" Thorin hissed.

"Now dismount and go greet Bilbo. And be polite!"

Thorin glared his father but did as he was told. As if on a cue also Frerin and Dís got off their pony and walked to their father. Dís whispered to Frerin that she thought Bilbo was cute. Frerin agreed and then turned to face his younger sister, a wide grin on his face.

"Wanna bet Thorin fails to make an impression?"

"No", Dís whispered back curtly. "We both know he fails so taking bets is quite unnecessary."

Dís turned out to be right. Thorin head-butted Bilbo, who got both hurt and extremely frightened. Frerin had to turn around so that nobody would've seen how he laughed. Thorin was daft, but Frerin hadn't imagined him to be daft enough to head-butt a hobbit. Bilbo hid once again behind his mother and Thrain sighed deeply. This wasn't working out at all how he had imagined. Now, he hadn't expected there to be love at first sight (Thorin and Bilbo were children, for Mahal's sake) but he had hoped Thorin to be more well-mannered. Then Thrain turned to see Frerin and Dís.

"You two", he said with a weary voice, and the siblings immediately stood taller, "could you play with Bilbo while I educate your brother a bit more?"

"Of course, Father", Dís said and went to greet Bilbo. She was only a year older than the hobbit prince and looked nowhere near as frightening as her brother. She smiled at Bilbo and said, "Hello Bilbo. I'm Dís. Would you like to play with me and Frerin? I promise we shan't head-butt you."

Bilbo looked at Belladonna for advice, and when she smiled approvingly, he nodded. "Okay. I'll show you my wooden animals!"

"Sounds great!" Dís said with clear joy in her voice. "Frerin, come along!"

The three of them ran inside the castle, laughing. Thorin grunted. Not that he actually cared. He was too old to play stupid kids' games, after all. He'd much rather train with his wooden swords with his best friend Dwalin, who tagged along the party that had arrived to the Shire. However, Thrain would not even hear about combat training now that they were in Bag End. Hobbits, unlike dwarfs, weren't into battles and heroism at all. They preferred simple things, like good food, flowers and doilies. So Thrain's order was clear: no fighting, even for training, as long as they were in the Shire. Thorin tried to protest, and so did also Dwalin, but Thrain's glare told them to shut their mouths.

"It's not fair", Thorin complained to Dwalin. "Being stuck here all summer is already bad enough but now we can't even train! That hobbit kid ruins my life."

Dwalin agreed and then suggested that they'd build a fortress to the garden where they could train in secrecy when the king wasn't around. They could also play some pranks from there. Thorin nodded and they went to choose the best location. They picked a tall pine and in three weeks' time they had built a bulky yet a quite magnificent fortress out of waste wood and metal scrap up to the branches. Thrain was impressed by Thorin and Dwalin's building skills, but he was not impressed when they started to throw water balloons at Bilbo, Dís and Frerin from there. Frerin didn't seem to mind, but Dís ended up yelling so much that her throat ached afterwards. And once again Thrain was forced to scold his eldest son.

As the years passed, Thrain and Belladonna became more worried each summer. Bilbo had become best friends with Frerin and Dís, but same could not be said about Thorin. They absolutely loathed each other. Whenever they were in the same room they'd always pick up a fight. Bilbo managed to scare Dís once when he came to her, his nose all bloody.

"By Mahal!" Dís shrieked. "What happened, Bilbo?"

"Thorin punched me", Bilbo answered. "And I punched him back."

Frerin roared with laughter and patted Bilbo's shoulder. "That's what I'm talking about! There's more in this hobbit than meets the eye, just saying. Oh, I'd be lying with my pants on fire if I said Thorin hasn't been craving for a good punch for years now..."

"We have to clean that up", Dís said strictly (and Bilbo and Frerin thought that if she carried on her strict manners she'd be ruling the world before long). "Your mother will get a fit if she sees this mess!"

That Bilbo knew to be true. His mother liked things neat and a bloody nose was most certainly not neat. Dís huffed and started to wash the blood off Bilbo's face. When she was done, nobody could possibly know he'd ever been punched in face. Well, it wasn't the first time Dís did that. She'd washed Frerin's face for more times that she could ever count.

"Are you going to tell Father and Mrs. Belladonna what Thorin did?" Frerin asked.

"No", Bilbo answered curtly. "This is just between Thorin and me. There's no need to meddle other people in this."

"Whatever did you do to make him punch you?" Dís asked, laughing a little.

"I beat him in golf. He got mad and punched me. There was no one else to see than Dwalin, and I bet he would've smacked me too if I hadn't run off."

"By Mahal", said Frerin. "Someday this loathing of yours will get you both in a whole lot of trouble. I'm telling you."

Little Frerin knew how right he was with his words.

Things didn't change by time. The year Bilbo came of age nobody could bear to let them be in the same room at the same time. Dwalin had gratefully stopped picking on him because it wasn't funny anymore, but Thorin just carried on like he always did. And it was very trying for both Thrain and Belladonna. One night in Erebor Belladonna was doing her needlework, muttering, as Thrain came in her room.

"You mutter", he said.

"I do not mutter", Belladonna snapped.

"Aye you do. You do it, lass, when something troubles you."

Belladonna dropped her needle on the fabric. "I was thinking of our sons. I doubt they will ever start to get along, let alone become friends. And then I thought... maybe it was a mistake to assume they would get married one day."

Thrain sat next to her and pressed his large hand over her shoulder encouragingly. "Belladonna, there is something you should know by now. Sometimes dwarf lads pick on those they love."

Belladonna looked at him disbelievingly. "And you assume this is the deal with Thorin?"

Thrain nodded. Belladonna let out a deep breath and asked, "So, are we still going to get them together?"

"Aye. We cannot give up now and you know it, lass."

"Oh, stop calling me that! I have not been a lass for great many years!"

Thrain laughed a bit and stated that no matter how old Belladonna got, he'd still always see her a lass.

Meanwhile Frerin and Dís, who was pregnant with her first child, were whispering together. They were extremely fed up to Bilbo and Thorin's constant bickering and they decided to do whatever it would take to make them like each other. At some point Dwalin joined them. He was also quite fed up and promised to help the Durin siblings. He also provided some nice inside information. Dís was overjoyed when Dwalin said that Thorin only picked on Bilbo because he liked him. "Oh well, like is too lame a word. I'd say love is more accurate." Frerin rubbed his hands together and promised to check if Bilbo felt the same way. The three of them made an oath to each other that they would stop at nothing to get Thorin and Bilbo together. And then they started to work. Even though Dís was pregnant and was feeling quite uncomfortable, she still had the necessary energy to boss people around. She immediately ordered the servants to clean up the throne room and add there a few more plants to make it more pleasant for a hobbit. It would be the perfect place to start courting, right under the Heart of the Mountain, the Arkenstone.

While Dís was bossing the servants (and her husband) around, Frerin went looking for Bilbo. The hobbit wasn't hard to find. He was in the archives of Erebor, reading as he always did. From his point of view there wasn't much to do in Erebor so he read a lot. Frerin sneaked behind Bilbo and looked over his shoulder to see what he was reading. It looked like the lineage of house Durin. Bilbo was staring at Thorin's name.

"So", Frerin said and gave Bilbo quite a startle, "do I take it you don't hate my brother as much as you tell people?"

Bilbo scowled. "And do I take it you enjoy spying on me?"

"Well, now that you mention it, yes, it is quite entertaining indeed. So, answer my question. Do you like Thorin?"

"I... well, I suppose... I suppose I do."

Frerin clapped his hands together enthusiastically. "Then come on! You have to tell him that!" He grabbed Bilbo's wrist and dragged him from the archives. Bilbo couldn't help but wonder what had got into his good friend. Frerin was all too cheerful for a dwarf, had always been, but now he was even more overly enthusiastic than usually. And Bilbo didn't understand why he should tell Thorin that he liked him. Surely Thorin would not feel the same way, not after all those years of what could only be called hate...

"Right, we have to make you look nice", Frerin said once they arrived in his room. Dwalin was still in there, planning how he would lure Thorin into the throne room without making it suspicious. Frerin huffed and said, "Dwalin, out. I have a hobbit to prepare."

"Prepare to what?" Bilbo demanded. Dwalin grinned.

"Right, I'm off. Gotta find Thorin. Take care of the Halfling, Frerin."

"Aye aye, sir!"

"Frerin, what in the Valar's name is going on?" Bilbo asked and squealed as Frerin took off his clothes and pushed him into the bathtub. "Ow! You got soap in my eye!"

"Oh, sorry", Frerin apologized. "Wasn't on purpose, I swear. Now hold still, you have to be at your best tonight."

"Frerin! Stop sounding like my mother and tell me at once what the hell is going on!"

"Can't. It's a secret."

Bilbo glared him. "Blasted dwarfs and their stubbornness..."

"Thank you very much for the compliment."

Once Frerin was done, Dís came to check they were ready. Bilbo glared both of them and said that he wouldn't come to Erebor ever again if this secrecy didn't stop. Dís just smiled and said everything would come clear soon enough.

"Is everything ready?" Frerin asked.

Dís nodded. "As ready as can be. Dwalin's still looking for Thorin but I think he'll find him soon."

"Good. Let's get going."

"Could someone please tell me..." Bilbo started but was cruelly interrupted when his mother came in and said, "Everything is ready. Dwalin found Thorin."

Dís and Frerin smirked at each other and dragged Bilbo out of the room. Belladonna followed them with a smile on her face. She was quite fond of young Dís, especially now that she was with child. Dís had come to her many times to ask about things, especially about childbirth and whether or not it hurt as much as people said. Belladonna had been more than pleased to answer all those questions.

"Ah, here we are", Dís said when they had reached the doors of the throne room.

"What are we doing here?" asked Bilbo. He grew more confused every moment.

"Right, here's the deal", said Frerin. "You like Thorin. Thorin likes you. You both should go for it. Was I clear enough?"

Before Bilbo could even try to complain, Frerin and Dís pushed him into the throne room and closed the doors, grinning at each other. On the other side of the room Dwalin did the same to Thorin, only that he received a slap around his head from his older brother Balin for "manhandling" the Heir under the Mountain. But the mission was accomplished, even if Thorin did yell at Dwalin for locking him in. Dwalin couldn't hold back a roaring laughter.

"What's so funny?" Bilbo asked casually from Thorin.

Thorin snorted. "Apparently he thinks I have a thing for you and locking us up in here was the flash of genius of the decade."

"Your brother and sister think the same", Bilbo answered. He wouldn't say anything about his feelings, not until he was absolutely sure they'd be returned...

"Some friends we have", Thorin sighed. "As if something could ever happen between us. I wonder how they can be foolish enough to assume so. It's absolutely ridiculous."

"Yeah, so it is", Bilbo said half-heartedly. Well, that sure proved it. Thorin cared nothing for him and he'd been foolish to think otherwise... For some reason it hurt Bilbo more than it should have. Sure, he cared for Thorin, but surely it was mere admiration of his strength and bearing, nothing more. So why did it hurt so badly? Bilbo didn't understand.

"It's not even like we were friends", Thorin continued. "It was stupid of our parents to try to get us together. Father knows well enough that I won't need a consort now that Dís is pregnant."

"So... are the gold and the Arkenstone all you care about?" Bilbo asked. "What about everything else?"

Thorin looked puzzled. "What else is there?"

"Nothing. I get it. I could never stand a chance. Have a nice life with the lifeless jewels, Thorin."

"What the... Bilbo, wait!"

But Bilbo had already left the room and told Belladonna that he wouldn't stay in Erebor for another minute. Frerin and Dís looked at each other with worry, but they knew better than try to turn Bilbo's head. Frerin offered to come see them off while Dís and Dwalin went into the throne room and started to yell at Thorin, calling him names king Thrain would have most likely disapproved. Frerin went to the stables, helped Bilbo to mount a pony and said, "I'm so sorry, Bilbo. I didn't think my brother would be that daft."

"It's not your fault, Frerin", Bilbo sighed. "I was stupid enough to think even for a moment there might be room in his heart for anything else than that blasted stone."

Then they took off. At the same time Balin had joined Dís and Dwalin in their mission to tell Thorin off so badly he'd remember it for the rest of his life. While the younger ones used quite rude words (Balin made mental note to wash Dwalin's mouth with soap after they were done), Balin was more discreet but his words hit harder.

"'What else is there?'" Balin said mimicking Thorin's voice. "He asks you if you only care about the gold and the Arkenstone, and you have the nerve to answer, 'What else?'"

Thorin scowled. "It was stupid, I know. He took me off guard, so stop yelling at me!"

"You should write a book: How to Offend Hobbits with Five Syllables or Less", Dwalin mocked.

"You are such an arse!" Dís screamed. "Did you see Bilbo's face?! It was as if you'd stabbed him, you... oh..."

"Yes, what?"

Dís clutched her belly. "The baby. He's coming."

Thorin, Balin and Dwalin looked at Dís with horror. It was two weeks too early, she could not possibly give birth now! Dwalin rushed to look for Thrain, Dís's husband, and the midwife while Thorin and Balin helped her back in her room. As if things weren't already going badly enough, one of the guards that had left with Bilbo, Belladonna and Frerin came in running and gasped that they had been attacked by a dragon. Dís screamed in pain for both her baby and her brother and friend.

"Go, laddie", Balin urged Thorin. "I'll take care of Lady Dís."

Thorin rushed to the stables and told his pony, Minty, to show the meaning of haste. Minty did as she was told to. Thorin had never prayed so hard. Bilbo and Frerin... they had to be alright, they had to be safe. Thank Mahal Minty was the fastest pony ever to gallop in Middle-Earth. Thorin thought of Bilbo, of Frerin, and of Dís's child. They all had to survive. They just had to. (Thorin wasn't too worried about Dís's survival. That woman could get incinerated by a dragon and walk out of it unharmed.)

The scene of the tragedy was just at the edge of the realm of Mirkwood. There were dead, bloody bodies everywhere. Thorin dismounted and ran around, yelling for Bilbo and his brother. Quite soon he found Belladonna who had only minor wounds but who was just as frantic as Thorin was. Finally he found Frerin. His baby brother was bleeding and had troubles with breathing. Frerin looked at Thorin and coughed.

"I- I'm so sorry, brother", he managed. "I- I tried to keep him safe but I couldn't. Th- the dragon... it took him..."

"Frerin, don't speak", Thorin pleaded. "You'll be fine. You must live. You'll get better and then we'll go find Bilbo together. It'll be fine, I promise."

"No, Thorin", Frerin coughed. "I am... beyond help now. Find... find Bilbo and... make things right."

Frerin coughed some more blood and drew his last breath. Belladonna had sunk on the ground with despair. Thorin held his brother and cried. His whole world was coming crumbling down on him. He was such a fool. It hadn't been his father, Frerin, Dís, Dwalin or Belladonna who had been stupid to think he and Bilbo could've had a future together. He was the only idiot, had always been.

"Frerin, I promise to avenge you", Thorin whispered. "And I'll find Bilbo even if it were the last thing I'd ever do."

The storyline will be a tad darker than in the movie Swan Princess. I'll keep as faithful to the movie as I can but there were things I were quite forced to alter. You'll see them then. And I kept some of the lines the characters had in the movie (only the funniest ones, though). English is not my first language, so please point out any grammatical errors I might've made.

Edit: Thank you for Painton to point out I'd forgotten a line. I really should be more careful when I write xD It's edited now.
