Chapter 1.

Bella's P.O.V

(Before their 17th birthday party)

I walked out of my bathroom and walked over to my bed. I grabbed my dress off the bed. It's one that looks exactly the same as the one my mom wore when she infiltrated the fire nation with Aang, Sokka my uncle, and Toph my godmother. (A:N The dress that Katara wore the third season) The only difference is with her necklace, instead of all the gems being red, half of them are midnight blue. After I put the dress on, I decided to keep my hair which is shoulder length down except for the top-knot that the royals are forced to wear. I also had bangs that stopped at my shoulders (A:N Azula's bangs and top-knot). I walked over to my dresser and sat down. I waterbended the water out of my hair and gave it to my plants that were in the corner in my room. I started to brush my brown hair which also has four highlights. I looked in the mirror and saw my topaz eyes.

That moment there was a knock on my door. I walked over to the door and opened it. There stood my brother, Emmett. He was wearing the same thing that all the princes in the royal family are forced to wear to their 17th birthday party. (A:N What Zuko wore in The Awaking) He has muscles and is physical fit, but really deep down he is just a soft teddy bear. He too has topaz eyes. In fact we have the same eye color as everyone in my family. In fact everyone in the royal family has had topaz eyes since about ever. There has never been any record of any of the royal family members not having topaz eyes.

The reason for that is that the royal family is not really human. Ever since the world has been divided into the four nations, the royal family has had a special power. We are what most people would call vampires. We are immortal, have super speed, and our senses are improved. We also can't eat normal food. Most people believe that all vampires drink human blood. The royal family didn't want to lose anyone in their nation or have anyone get suspicious of them so they drink blood from animals.

The difference between what we are and what most people think of when they think about vampires are many things. One thing is that we don't turn into bats. We also down burn in the sun. When we do get caught in the sun, our skin sparkles like there are a million super tiny diamonds. We also don't sleep in coffins. In fact we don't sleep at all. We also get changed because of the venom that we create when we drink blood. (A:N I will explain how Zuko and Katara had Emmett and Bella in a later chapter.) Some of us also have special powers.

My whole family is able to have musical instruments play it self so we write songs often. My father can also tell when someone is about to attack him. So it is impossible to snick up on him. Trust me. Emmett has done it so many times. My mother can also bloodbend. I am the only one beside my mother that can do that. Emmett is the fastest vampire ever recorded. I can also block other vampire's powers. My father is still trying to bring peace to the entire world, so Emmett and I both have tattoos of the four elements. Emmett has them in the avatar cycle on his back. I have the avatar cycle on my stomach. I also have the water and fire symbols my right arm and the air and earth symbol going left arm. Emmett and I also have four highlights. In I am looking at the floor, on the top left is a neon yellow highlight, the top right has a neon green highlight. The bottom left has a blood red highlight. Last on the bottom right is a midnight blue highlight.

There is one thing that is different about me and Emmett than other vampires. We are only half vampires. We don't become full vampires until our eighteen birthdays.

In this world there is a being called The Avatar. The avatar is the only person who can bend all four elements.

Our world is divided into four parts. The Water Tribe, The Air Temples, The Earth Kingdom, and The Fire Nation. Each nation can control one element or as we call it bending The Water Tribe has waterbenders, The Air Temples have airbenders, The Earth Kingdom has earthbender, and The Fire Nation have firebenders. Not everyone is a bender. A brother could be a bender while the sister isn't one. Also if you are an earth bender, there is a chance that you could be a metalbender. Some earth benders can listen to the earth so well that they are able to also control metal.

Everyone in my family is a bender. My father is a fire bender and is the royalty by birth. My mother is a water bender and was changed into a vampire after she married my father. She knew that he was a vampire and she still loved him. Now that is true love. Emmett and I are unique. We can both bend water and fire. Other than the Avatar, no one can bend more than one element. We don't know how we can bend both elements but we don't care.

Now that I explained the vampires in my world, I think you should know what my parents went through with the war and helping the Avatar.(A:N I got this off of Wikipedia but I changed the words a little)

One hundred and seventeen years before Emmett and I were born, a 12-year-old Airbender named Aang learned that he was the next Avatar. Being fearful of the heavy responsibilities of stopping an impending world war and with the impending separation from his mentor Monk Gyatso, Aang flees from his home in the Southern Air Temple on his flying bison, Appa, During a fierce storm, they crashed into the ocean, and Aang's Avatar state freezes them in an iceberg.

Aang and Appa were awoken a hundred years later by two siblings of the Southern Water Tribe, my mother and my uncle Sokka. Aang learns that the Fire Nation started a war a hundred years ago just after his disappearance. The Fire Nation's opening move in its campaign for global conquest was to launch a genocidal attack on the Air Nomads which drove Aang's entire race to extinction, thus making him "the last Airbender" left alive. He realizes that he must fulfill his destiny of becoming the Avatar and return balance to the world by defeating the Fire Nation. Aang sets out to master the three unlearned elements: Water, Earth, and Fire. With Katara and Sokka, Aang decides to head first to the North Pole to find a Waterbending master.

Aang soon discovers that Sozin's Comet, which Fire Lord Sozin used as a power supply to start the war, will return in the coming summer, giving the Fire Nation enough power to ultimately accomplish victory. Aang realizes that he must master all four elements and end the war before this time. For most of their journey to the North Pole, the group is pursued by my father Zuko, a banished Fire Nation prince and son of Fire Lord Ozai who is obsessed with capturing Aang to restore his lost honor.

After leaving the North Pole and mastering Waterbending, Aang travels to the Earth Kingdom to master Earthbending. There, the group meets Toph, my godmother, and a blind Earthbending prodigy who becomes Aang's second teacher. The heroes discover information about an upcoming solar eclipse which would leave the Fire Nation powerless and open to invasion. They struggle to reach the Earth King with this vital information, but are detoured by Appa's kidnapping. The psychologically self-tormented Zuko, his sister Azula, and her two friends Mai who had a huge crush on my father, and Ty Lee chase the group as they struggle to reach Ba Sing Se. Azula engineers a coup from within that topples the Earth King and destroys any hope of a large-scale invasion of the Fire Nation.

The group recovers from the fall of Ba Sing Se, and travel to the planned invasion site. On the day of the solar eclipse, Aang's group and a smaller band of warriors launch a smaller invasion, which ultimately fails. Zuko confronts his father and defects from the Fire Nation. After a series of events, he manages to gain the trust of the protagonists and becomes Aang's firebending teacher. Aang and Zuko unlock the firebending secrets of the "Sun Warriors" and Sokka and Zuko travel to a Fire Nation prison to rescue Sokka's father and Suki, my aunt.

On the day of Sozin's Comet, Fire Lord Ozai harnesses the comet's power to start a genocidal campaign to destroy the rest of the world. Aang and his friends face the self-proclaimed "Phoenix King" Ozai, Azula (now crowned as the new Fire Lord by Ozai), and the Fire Nation army. Aang confronts and defeats Ozai while the Order of the White Lotus takes back Ba Sing Se from the Fire Nation. At the same time, Zuko is incapacitated by Azula, whom Katara then defeats. Zuko becomes the new Fire Lord and promises to help re-build the world alongside Aang.

So know you know how the Avatar ended the war. What you don't know is what happened after. Avatar Aang and Toph got married. While my mother and Toph were on a mission to get rid of some of the troops from the Earth Kingdom, Azula broke out of jail. The night that my mother and Toph came home Azula snuck into Toph's house. Aang was sleeping and he didn't sense her coming. Toph was about a mile away and while she was running back, she sensed Azula. She ran as fast as she could for she was human at the time. But atlast she as too late. As soon as the house came into view, she sensed the lighting bolt. By the time she got to their room, Azula was gone and Aang was dead. Toph then vowed that she would be the next avatar's earth bending master so they could kill Azula and get even for killing her husband.

That's enough about the past. Now let's go to our party.
