Trouble With The Crown

== Prologue: ==
There was once a lovely kingdom, ruled by a fair king and queen. They were loved by their people, and even the nearby kingdoms. Everything was peaceful and lovely until disaster struck. On the princess's second birthday, the king and queen were kidnapped. Troops were sent to search for them, but they were never found. After a year of searching everywhere, the king and queen were declared dead. The king's brother then claimed the throne. He was kind and passionate, but you know what they say "Unlimited power corrupts the person", and that is what happened. He became evil and hungry for power. The princess stood watching as he started turning the once beautiful kingdom into an ugly dark place. She always thought there was nothing she could do, that is until she discovered something that could return everything to the way it was before.
== The Letter ==
Luna awoke at the sound of a bird tapping on her window cell. There was nothing she loved more than to start her morning listening to the beautiful chirping of birds. She even named them! She got out of her bed and removed her cherry-red hair from her face. Oh, this was Willow. She was a beautiful bird with blue and yellow feathers. Luna went and opened the window for her to come in. Willow flew in and landed on her shoulder. Luna started rubbing her soft cheek, and Willow started chirping melodically. Just then, the room's door opened, showing a beautiful girl with shoulder-length raven black hair and midnight blue eyes. The bird instantaneously flew from Luna's shoulder and fluttered down on the girls's.
"Look! It likes you. Who am I kidding? All the creatures like you," Luna spoke.
"Don't overreact! I am sure it likes you more," the girl spoke in a soft voice. Her cherry red lips curved into a big smile.
This was Iris, Luna's best friend. To be fair, Luna had only two friends, Iris and Asher. They were her cousins so technically, she had no friends. In the stories Luna reads, the son and daughter of the evil people are always evil, but not in her story. Iris and Asher were nice, kind, generous, and the complete opposite of their parents.
"William just finished preparing breakfast. Today's dish is eggs and bacon! You don't want to miss it," Iris said as she played with the bird.
"I will be down in a minute! Just don't finish all the bacon," Luna laughed as Iris politely went out of the room. Luna closed the door, and started changing. She wore a long white dress covered in flowers, with a leather, brown belt surrounding her waste. She swept her hair into a fancy roll and placed a red bandana on top. Her green eyes gleamed as she hopped down the stairs and into the dinning room. As expected, her uncle and his wife weren't there. They refused to eat with them. They thought they were higher than this.
"Good morning, Princess Luna," William, her faithful butler, greeted her.
"Morning, William. How many times did I tell you to just call me Luna," she replied as she took her seat on the table. Luna sat beside Iris and Asher sat beside Iris. William served them breakfast.
"What would you like to do for today," Luna asked them as they started eating.
"Maybe we can go have a stroll in the garden. I mean there is nothing else we can do," Asher volunteered.
Asher looked exactly like his sister since they were twins. He had the same raven black hair and the sparkling midnight blue eyes. One time Iris cut her hair and Luna wasn't able to tell the difference between her and Asher.
"Sounds good to me," Iris said, supporting her brother's idea.
"Fine by me," Luna said, not wanting to be the only one to disagree.
After they finished breakfast, which was very delicious, they headed off to the garden. As they walked, the butterflies and birds in the area hovered over them, Iris especially. If Iris had a special talent, it would be that she could attract all the animals in the nearby area. Despite Luna's love for animals, she never really managed to get their attention when Iris was around.
"What is that," Luna asked as she noticed a piece of crumbled, yellowed paper near some bright red roses. She bent and picked it up. It was sent from "Ancela Prison."
"Wasn't that prison buried hundreds of years ago by a horrible earthquake," Iris asked as she read over Luna's shoulder.
"That is what I was told," Luna replied as she tried opening the envelope to read the message inside. Finally, after six tries, she managed to open it.

Please help us! We are trapped! We aren't sure if this letter will get to you, but we hope it will. Trevor isn't as nice as he seems to be. He is the reason we are in this ominous place. He wants to take control over the kingdom. To whomever is reading the letter, please rescue us.
Yours sincerely:
R and Z.

The letter was sent four years ago. That didn't make any sense. How come the letter was still there? Four years was a long time for a person to keep a letter. Plus, what did they need saving from? Who were R and Z? Luna looked at her friends, hoping to find some hint of recognizing in their eyes. Unfortunately, they looked just as confused as she is.
