On a beautiful day in the lake, the mane six are watching swans swimming in grace and beauty. "Aren't they beautiful, girls? Who knew swans are magnificent creatures." said Fluttershy. "I know they are, I wonder what they're capable of." said Twilight.

While looking at them, they hear the Book of Disney calling them which spooks the swans. "It's the Book of Disney." said Applejack. "Come on, every pony. Let's go." said Rainbow Dash.

When they got there, Twilight went to the book and opened the next chapter. The next story is The Swan Princess. She begins to read,

"Once upon a time, lived a lonely King named William who is desired to have a child. One day, a daughter was born and she was named Odette. On her christening, a young prince named Derek gave her a necklace as a present. What William doesn't knkw that an evil wizard named Rothbart wants to take the throne himself and uses dark power to do so. But, his plan was foiled when William and his men invaded his lair and banished him from the kingdom. Rothbart vows that when he comes back, he will take everything from William and claim it as his. As the years pass, William and the Queen Uberta made a deal about their two children meeting each other every summer and will be married when they get older. But, Odette and Derek didn't get along. The servants and the citizens have high hopes on the two getting married. When they became adults, they finally fell in love with each other. Because of that, Derek arranged the marriage. Odette wasn't quite happy about it because Derek only loves her for her beauty, that's it. So sadly, the wedding was called off and Odette went back to her kingdom. On the way back, Rothbart showed up out of nowhere and transformed into a monstrous creature. He attacks the carriage and kidnaps Odette. The captain of the guard managed to survive the attack and tells Derek that Odette has gone missing. He went to her as quickly as possible, but all he finds was a locket and the dying William. Before he dies, he told him it's not what it seems. Derek was heartbroken at this and will never see Odette again. Meanwhile, Odette was transformed into a swan by Rothbart. She turns into a swan by day, and a human by night when the moon is full. Rothbart wants to marry the princess so he can take over the kingdom, but Odette refuses. Because of that, Rothbart kept her as a prisoner until she says yes."

Once Twilight is done reading, she and her friends get sucked into the book and goes to the adventure.

...

They ended up in a forest with a lake nearby. There, they saw a swan being transformed into a princess. That princess was Odette.

"Oh my Celestia. Is it really her?" Applejack whispered. "I believe so, since Rothbart turned her into swan. Poor dear." said Rarity. "How can we help her?" Rainbow Dash asked. "We can. We've saved princesses before, we can do it again." said Twilight. "Good idea. I just don't know why powerful villains are after princesses." said Pinkie. "So, can we go and see her now?" Fluttershy asked. "Oh, of course." said Twilight.

They walked up to Odette and Twilight asked, "Um, excuse me." Odette turned around and saw the mane six. "Oh, hello. What are you doing here in a terrible place?" Odette asked. "Why do you think it's dangerous, darling?" Rarity asked. "Because of Rothbart. He's been doing this to me for a long time and I don't know how to break the spell. Please, help me." Odette pleaded. "Ah, don't be upset sugar cube. My friends and I are here to help." said Applejack. "Thank you. I really appreciate it. So, can you introduce yourselves since you're going to help me?" Odette asked.

"I'm Twilight Sparkle and these are my friends. Rainbow Dash, Applejack, Rarity, Fluttershy, and Pinkie Pie." Twilight introduced. "Nice to meet you. My name is Odette." said Odette. "That's a beautiful name." said Rarity. "Thank you." said Odette. "Okay, now that we know each other. Let's find out how to get rid of Odette's curse." said Rainbow Dash. "I know! True loves kiss!" Pinkie shouted. Everyone stared at her for that. "Are you sure it'll work?" Odette asked. "Well, it happens everywhere. Love solves everything." Pinkie explained.

"Your right, Pinkie. But, we don't know who Odette is in love with. Maybe a prince." said Fluttershy. "I am in love, Fluttershy. Prince Derek. I've known him since we were children and he on,y loves me for my beauty. I know he loves me for me, but he doesn't tell me." Odette explained. That gave Twilight an idea. "That's it! I know how to break the spell!" she shouted. "Really? How?" Applejack asked. "In order to break the spell, Derek must tell Odette how he feels for her. Kinda like a vow." Twilight explained. "Or in this case, the act of true love." said Rarity. "No, Rarity. It's not like that. It's far more different than what Anna did." said Twilight. "If Derek is the guy you love, that means he's the one who can break the spell." said Rainbow Dash. "That's right." said Odette.

Suddenly, they hear Rothbart coming and the mane six have to hide from him. "Quick, hide. I don't want him to see you." said Odette as she lets the mane six hide in the trees. Rothbart showed up in an armor and makes everything pretty around them. "Well well well, princess. It seems that you might change your mind about me. Will you marry me?" Rothbart asked as he kneeled down to have Odette as his bride. "Every night is the same questions and every time I give the same answer. I'd die first." Odette explained.

Rothbart groaned in annoyance and said, "You will marry me, I want to take over your father's kingdom and you will rule my side. If you don't marry me, I'll kill you." Rothbart's words made Odette cry and the sun begins to rise. Because of this, she turned back into a swan. Rothbart laughed evilly as he leaves the forest.

The mane six came out of their hiding place to comfort Odette.

...

The next morning, the mane six and Odette are figuring out how to find Derek and break the spell.

"Now that we know Derek is the one who can break the spell, we need to find him." said Fluttershy. "Yeah, but we don't know where he is. We should find his castle first, then find Derek." said Applejack. "Your right. We should find a map or ask for directions." said Twilight. "Well, I do remember Rothbart has a map to every kingdom near here. So, we might find the castle there." said Odette. "Yeah, let's do it!" Rainbow Dash shouted. "And I know where to find the map." said Odette.

The place she knows is Rothbart's castle. So, she and the mane six sneak into one of the rooms and saw the map right there. "I spy with my little eye, something that can help us find the prince." said Pinkie as she sees the map on top of the books. "Good eye, Pinkie. Now let's snatch it and get the hay out of here." said Rarity. Twilight uses her magic to pick up the map and gives it to Odette. "Alright. Let's go." she said.

But before they can leave, Rothbart's hag assistant saw them and chases after them. Applejack went to her and ran her over like a bull. Rainbow Dash joined in by kicking her, then, both of them began kicking her like a ball. "That's enough, you two. Put her down before you accidentally kill her." said Twilight. Applejack and Rainbow Dash stopped kicking her and ran off with their friends. They managed to get out of the castle safely.

When they got to the lake, Twilight and Odette reads the map to find Derek. "Yes, there it is. Right there." said Odette. "Hmm, it doesn't look too far." said Twilight. "That means we'll get Derek asap." said Pinkie. "That means we better get him now before Rothbart comes back." said Applejack. "Yeah, I don't want him to kill Odette like he warned her last night." said Rainbow Dash. "Then let's get going." said Rarity.

So, the mane six and Odette searched for Derek to break the curse.

...

When it was close to sunset, the mane six and Odette looked far and wide for Derek, but could not find him.

"Derek. Derek, where are you?" Pinkie shouted. "We've searched for hours, but could not find him." said Fluttershy. "We will find him, we just have to look even harder." said Twilight. "I'm sure Derek will love me for me." said Odette. "I'm sure he will, darling. If he loves you that much and will say the vows of everlasting love." said Rarity.

Rainbow Dash was flying through the forest and saw someone not far from her. She went closer to him and almost got shot at. The guy who almost shot her was Derek. Rainbiw Dash flew as fast as she could to get to her friends. "What happened? Did you find Derek?" Odette asked. "Yep, found him. And he tried to kill me." said Rainbow Dash. "Uh oh." Applejack muttered as she saw Derek running after them.

He was about to shoot them until. WHAM! Pinkie knocked him out with a huge tree branch. "Pinkie Pie!" Odette shouted. "What? He tried to kill Rainbow Dash." said Pinkie. "But, you don't have to knock him out." said Odette. "Don't worry, she did it last time to a handsome looking guy snuck up to her." said Twilight.

After that, the mane six and Odette took Derek back to the lake so he can break the spell. They hear him groaning as he was about to wake up. "He's waking up. Hurry, Odette. You better get to the lake so you can turn back into a human." said Fluttershy. Odette went to the lake and waits for the transformation. "Okay, any minute now." said Applejack.

They saw Derek waking up and rubbing his head. "Who are you guys?" he asked. "We'll explain later. Now, we would like you to see this beautiful woman." said Twilight. Odette is now transforming back to a human while everyone is watching. Derek could not believe his eyes on what he's seeing. "Hello, Derek." said Odette. Derek went to her and lifted her high in the air. Then, they shared a kiss. The mane six awed at the moment.

"Oh, Odette. I've missed you so much!" said Derek. "I missed you too, Derek. I've been thinking about you this whole time." said Odette. "Me too. And, who are your friends?" Derek asked. "These are the girls who helped find you to break my curse." said Odette. "What curse?" Derek asked. "You see, Derek. An evil wizard named Rothbart casted a spell on Odette. She turns into a swan by day and a human by night. The only cure to break the spell is for you to say your vows of everlasting love. If you don't do it soon, Rothbart will kill her." Twilight explained. Derek gasped and asked, "Odette, is this true? Your under a spell?" "Yes." said Odette.

"You better say the vows now." said Rainbow Dash impatiently. "She'll die if you don't say them." said Applejack. "Ok ok, then. I'll say the vows." said Derek. "We're listening." said Pinkie. Derek clears his throat and says, "Odette, I." But, he was stopped when they all hear Rothbart calling for Odette. "Oh no, it's Rothbart." said Fluttershy. "We better hide." said Rarity. "Go, everyone. I'll take care of Rothbart." said Odette. "But, what about the vows?" Rainbow Dash asked. "I have an idea. I'll say the vows to Odette at the ball tomorrow night. Promise you'll be there." said Derek as he was about to leave. "We will!" Twilight shouted.

Before they can hide, Rothbart showed up out of nowhere. "Surprise!" he shouted. "Rothbart!" Rainbow Dash growled. "Oh, you know me. How interesting." said Rothbart. "We've been helping Odette find her true love. All you have to do is to remove the spell." Twilight ordered. Rothbart chuckled evilly and said, "I'm afraid I can't do that. I don't like removing my spells, it ruins my fun torturing my victims."

"You take that back!" Rainbow Dash shouted. "You can't do this to her!" Rarity yelled. "Blah blah blah, you girls have annoying voices. As for you Odette, there will be no moon tomorrow and I'm going to keep you held captive until you die since you've been refusing to marry me." Rothbart explained. "What? You want to kill her with your spell?!" Fluttershy asked in horror. "Yes. And don't you think about getting in my way!" said Rothbart as he disappeared.

After that happened, Odette starts crying. Applejack went to her to comfort her. "There there, sugar cube. It'll be alright, you'll see. I promise that Derek will break the spell by tomorrow night." she said. "But, Rothbart still has me captive and I'll die tomorrow." Odette cried. "No you won't. We are going to keep you safe until we can get you to Derek." said Pinkie. "Speaking of safe, I think we need to go to Derek's castle right now so that Odette won't die from the spell." said Rainbow Dash. "Great idea. Now, let's go before Rothbart finds out." said Fluttershy.

But before they can leave, Rothbart showed up out of nowhere and knocked them out with his magic.

...

The next day, Rothbart has locked the mane six and Odette in a watery dungeon.

"You won't get away with this, Rothbart! It's not even dark yet!" Twilight shouted. Rothbart laughed at them and said, "Of course I got away with it. Too bad you girls are too weak to stop me. Now, if you'll excuse me. I have a party to go to." Then he left.

"Oh, Twilight. What are we gonna do? It's almost sunset, and I'm close to dying." said Odette. "Don't give up hope, Odette. We'll get you outta here before Derek can say his vows." Twilight promised. "And we better get outta here fast! Better use that spell, Twilight." said Applejack. "I was just about to do it." said Twilight as she uses her magic to break through the wall in order to escape. "Oh yeah!" Rainbow Dash shouted.

Once they escaped, they were encountered by hungry alligators. "Uh oh." said Pinkie. "I didn't expect the gators to be here." said Rarity. "Don't worry, we can fight them!" Rainbow Dash shouted. "Odette, you have to go to the castle. Quickly. Don't worry about us, we'll catch up with you." said Twilight. "Ok, but be careful." said Odette as she flies away in order to get to the castle.

"Let's kick some butt!" Pinkie shouted as she unleashed her party cannon, causing the confetti to get into the gators mouths. They tried to get it out of them, but the mane six attacked them immediatley. Rainbow Dash does the punching and the kicking, Applejack is the kicker, Rarity does martial arts, Pinkie uses her cannon, and Fluttershy does her stare.

Once the gators are defeated, the mane six head to the castle to meet Odette.

...

When they got there, it was a complete shock. They saw Odette trying to get inside while watching Derek dancing with someone who looks like her.

"Odette!" the mane six shouted. "Girls, hurry! I think Derek is going to say the vows of everlasting love to the wrong girl!" Odette shouted. "Oh no. We've got to warn him." said Rarity. "I think it's too late for that, Rarity. Look." said Fluttershy. They can hear Derek saying the vows of everlasting love to the wrong person. "Those are my vows of everlasting love." he said. "Derek! No!" Odette shouted as she begins to collapse and falls, but Rainbow Dash catches her. "Oh no, Odette." Fluttershy shouted. "We're too late." said Twilight. "Not for me!" Applejack shouted as she ran to the entrance of the castle and slams it open.

Everyone was shocked to see the mane six, including Derek. "Girls, you made it. You just missed me saying the vows of everlasting love." said Derek. "Derek, listen to me. You said the vows to the wrong girl. That's not Odette. This is the real Odette on Rainbow Dash's back. We tried to warn you." Twilight explained. "Derek." Odette said in a weak voice. Derek was shocked in horror as he realized the truth. "If that's not Odette, who is this?" Derek asked. The lady disguised as Odette was Rothbart's hag assistant.

Suddenly, Rothbart appeared out of nowhere and scares everyone. "No more mister nice guy, not for me." he sang. "Rothbart!" Rainbow Dash growled. "Well, I can see you girls escaped from my trap and you're too late. I can see Odette is already dying because of me." Rothbart laughed. "You did this to her! Cure her, now!" Derek shouted. "Absolutely not. But, I can take her away from you!" said Rothbart as he grabs Odette from Rainbow Dash and disappeared. Odette screamed. "Odette!" Derek shouted. "Wow, I did not see this coming." said Pinkie.

"We have to go after him. He's going to kill Odette much quicker." said Twilight. "We better hurry! Let's go!" Derek shouted as he and the mane six chase after Rothbart to save Odette.

...

They ran as fast as they can to the forest while hearing Rothbart's voice.

"This is your last chance, Derek. I will only let you see her one last time." said Rothbart. "No!" Derek shouted. "Don't listen to him. He's lying." said Applejack. "We're coming, Odette." Rarity shouted. "She's got to be by the lake. I'm sure." said Fluttershy.

They finally reached to the lake where Odette was being held captive. As for Odette, she was found unconscious as she was transformed into a human. The mane six were in shock to see her like this. "Odette." Derek whispered as he ran towards her and held her in his arms. "Oh no, what have I done? Forgive me, Odette. Forgive me." "The spell. It completed its work." said Twilight.

Odette begins to wake up, much to their surprise. "Derek?" she said in a weak voice. "Yes, Odette. I'm here." said Derek. "It's okay, Odette. We're going to get you cured." said Rainbow Dash. "I feel so weak. I think I'm going to." said Odette. "No, don't say it. You're going to die, I promise." said Pinkie. "Please, Odette. The vow I made was for you." said Derek. "I know. I love you, Derek." said Odette as she touches Derek's cheek before she closes her eyes one last time.

"No!" Rainbow Dash cried. "She's gone. We didn't save her in time." Fluttershy cried. "Odette. I made a vow for her. Do you hear?! THE VOW I MADE WAS FOR HER!" Derek shouted.

"No need to shout." said Rothbart. "You again!" Rarity shouted. "Murderer!" Pinkie shouted. "Don't you dare let her die!" Derek shouted. "Oh, is that a threat?" Rothbart asked. "You bet it is a threat! You threatened us, so we'll threaten you!" Rainbow Dash shouted. "You have the power, now do it!" Derek shouted. Rothbart pushes them all to the ground with his magic and said, "Only if you defeat me."

And then, he transforms into a ferocious beast. The mane six and Derek gasped in horror. "The Great Animal." Derek muttered. "What?" Applejack shouted. "That's the creature that killed Odette's father. The Great Animal." Derek explained. "He's really terrifying." said Fluttershy. "We have to defeat him. It's the only way to save Odette." said Rainbow Dash. "I won't let her die!" Derek shouted as he pulls out his sword to defend himself. "We won't stop until you are gone for good!" Twilight shouted as she zaps Rothbart in the chest.

He fell to the ground and stood up immediatley. He smiled evilly at them as he starts flying higher and higher until they can't see him. "Where'd he go?" Applejack asked. "Come out, come out wherever you are!" Pinkie shouted. "Keep an eye in the sky, folks. He might attack us any minute now." said Twilight.

Suddenly, Rothbart showed up and grabbed Derek and lifts him up in the air. Rainbow Dash immediately went after him and starts punching. Rothbart lets go of Derek as he falls to the ground unconscious. "Derek!" Fluttershy shouted. "Better heal him quickly, Rarity." said Applejack. "I'm on it." said Rarity as she begins to heal the prince.

Rothbart and Rainbow Dash continue fighting as Derek is getting his strength back. "Derek! Is there anything you can kill him with?!" Rainbow Dash shouted as she was being grabbed by Rothbart. "I need a bow and arrow." said Derek. "Bow and arrow, coming up." said Rarity as she immediatley makes a bow and arrow with wood and string. Twilight uses her magic to make the arrow more powerful. "Get out of the way, Rainbow Dash. He's about to shoot!" Applejack shouted. Rainbow Dash got out of the way just in time.

Rothbart was chasing after her when she was landing to the ground. The mane six hides behind Derek as he was about to shoot his arrow. He made a very good shot at Rothbart. He was hit in the heart as he falls to the lake and explodes.

Rothbart was gone forever.

...

After the fight, the mane six and Derek did not cheer for victory. Instead, they mourn for the loss of Odette.

"Forgive me, Odette. I love you. For your kindness and courage. Now, I've lost you forever." said Derek as he kissed Odette's forehead and holds her tight. The mane six put their heads down in sadness. Suddenly, Odette begins to wake up because Derek said the viws of everlasting love and he truly means it. "Derek?" she asked. "Odette!" Derek shouted. "Oh, Derek!" Odette shouted as she embraced her true love.

She saw the mane six smiling at her. "Girls. You're here. Did you and Derek save me?" Odette asked. "We sure did. It's our job." said Rainbow Dash. "Oh, thank you so much. The spell is broken because of you. Now, I'll have a wonderful life with Derek." said Odette as she hugs the mane six. "I'm sure you will, Odette. He will take good care of you." said Rarity. "That's right. We are going to be together for the rest of our lives." said Derek as he kisses Odette on the lips.

"Well, girls. I think it's time for us to leave." said Twilight. "You're leaving? Where are you going?" Odette asked. "To other adventures where many people we can help. Who knows, we might help another princess." said Rainbow Dash. "Well, good luck with your adventures." said Odette. "Because of you, our love is more powerful than ever." said Derek.

"Bye, Odette. Bye, Derek." said the mane six as they disappear. "Bye, girls." Odette and Derek said.

...

When the Book of Disney dropped them off to home, the mane six got off the floor to dust themselves.

"Man, let me tell you. I sure like helping princesses." said Rainbow Dash. "Especially when princes come along for the rescue." said Rarity. "You know, the most important thing about that is love. It can be any kind of it." said Twilight.

...

That night, Twilight went to the Disney Journal to write her lesson. She wrote,

"What I learned today is about vows. Vows are like poems or words that you will never forget. But, the best kind of vows are about love. When you love someone, you should say something that you or loved one shall never forget. It's called The Vows of Everlasting Love."
