Chapter 1
Twilight Sparkle was so busy reading that she didn't notice the door of the library open. Sweetie Belle, who has been crying, tried to get Twilight's attention with no success. At last, she grabbed the book from Twilight to get her attention.
Twilight looked at Sweetie Belle and noticed the tears. "What happened?"
Sweetie Belle had difficulty speaking. She had to talk between sobs. "Rarity… is… gone… She… disappeared!"
"Sweetie Belle, Rarity probably just left to socialize or shop."
"No! She… she disappeared! I… saw it!"
Twilight became alert and shouted, "Spike! Take a letter!" Spike, who has been sleeping, woke up and got a scroll and quill.
"Dear Princess Celestia, Sweetie Belle has informed me that Rarity has disappeared. We don't know where she is, but it is important that she is found as soon as possible. She wields one of the elements of harmony, and without all of us, none of the elements will work. Your faithful student, Twilight Sparkle"
Spike stopped writing to say, "Twilight, you're not her student anymore."
Twilight blushed, "Oh. Then just say 'Sincerely, Twilight Sparkle'"
Spike sent the letter to Princess Celestia, and the three of them waited. Not long after, Spike got a letter. He opened it and read, "Dear Princess Twilight Sparkle, I am aware of her disappearance, and I believe I know her whereabouts. You and your friends need to come to canterlot promptly so I can explain."
Sweetie Belle stopped crying and asked, "Can I come with you?"
Twilight shook her head, "I'm sorry, Sweetie Belle. This might be dangerous."
Sweetie Belle pouted, "I want to go! She's my sister!"
Twilight knew that nothing will change her mind, so she nodded, "Alright, you can come with us, but don't put yourself in danger. I don't know what is going on, and you getting hurt will not make matters any better."
Sweetie Belle excitedly yelled, "I might get my cutie mark in saving my sister!"
Twilight and Spike both rolled their eyes and laughed as the three of them left to inform the others. After the mane six as well as Spike and Sweetie Belle were together, they took the train to Canterlot and hurried to the castle where Princess Celestia and Princess Luna both awaited their arrival.
Princess Celestia began explaining what happened, "The subjects of the Kingdom of Tendondon will be consumed by greed."
"Tendondon!" interrupted Pinkie Pie, "That's a funny word! Tendondon! Tendondon!" She giggled until she saw everyone glaring at her. She smiled innocently and remained silent for Princess Celestia to continue.
"As I was saying," Celestia continued, "Greed will consume the subjects of the kingdom, and as the prophecy stated, the only way for the kingdom to be saved is to summon the element of generosity."
"I thought we returned the elements to the Tree of Harmony!" Twilight thought allowed.
Princess Luna looked at Twilight and asked, "Do you remember what you said when I attempted to destroy the elements of harmony?"
Twilight nodded, "I said, 'You think you can destroy The Elements of Harmony just like that? Well, you're wrong, because the spirits of The Elements of Harmony are right here.'" Twilight realized what Princess Celestia meant. "Rarity is the spirit of generosity!"
Princess Celestia nodded, "That is correct, Twilight Sparkle. Rarity is the Princess of Tendondon."
"Rarity is a princess now?" Asked Twilight in shock.
"Not now," Princess Luna states, "She was a princess ever since she was born."
"But why doesn't she have wings?" Questioned Rainbow Dash, "I thought all princesses have are alicorns."
"Equestria princesses are alicorns, but Tendondon is not part of Equestria," Explained Celestia, "They are their own nation. Tendondon was built on the generosity of other ponies, so it was declared as the Kingdom of Generosity. The ponies there are very peaceful, but at sundown, everything will change."
"If they made my sister a princess, does that mean she's alright?" Asked Sweetie Belle.
Luna shook her head, "No, Sweetie Belle. Your sister is fine right now, but when greed takes over, she will be in danger. If greed is to consume her, Tendondon will fall, and the greed will spread into Equestria as well as every other nation. You must go to Tendondon and help Rarity defeat greed before she is consumed.
"There is a spell only she can use that will help you find out who is consumed by greed and who is not. After she casts the spell, everyone's eye color will change. If they are consumed by greed, their eyes will be green, but if they are not, their eyes will be gold."
"Woah there!" Exclaimed Applejack, "What about those of us who have green eyes?"
"Your eyes will still change gold." Stated Luna.
"Go at once!" Instructed Princess Celestia, "It is imperative that the spell is casted upon the entire kingdom before sundown or it will not work! The spell relies on the generosity of others to work."
The group took the Friendship Express to Tendondon ready to aid Rarity in protecting the kingdom from greed. Since the train ride from Canterlot to Tendondon is long, everyone chats distinctively amongst themselves. The train takes them far out of Equestria, and they soon find themselves in Tendondon.
