Hello! :] This is my first Avatar fanfiction, so please try to be nice with the comments. I'm going to try to write everything as accurately as I can but I can't make any promises. I've been planning out this story for a LONG time, but I've never actually put it onto paper. It's exciting to finally begin to write it out. Please rate and review, I hope to get as much input from readers as I can. I actually came across the name Siena in a movie; it was the name of a town. I decided to change it just a little to Sienna. Love the name, its Australian. :]

Disclaimer: I own nothing from Avatar, only my OC character Sienna along with any others you may not recognize.

Water... Earth... Fire... Air...

My grandmother used to tell me stories about the old days, a time of peace when the Avatar kept balance between the Water Tribes, Earth Kingdom, Fire Nation, and Air Nomads. But that all changed when the Fire Nation attacked.

Only the Avatar mastered all four elements. Only he could stop the ruthless firebenders. But when the world needed him most, he vanished.

A hundred years have passed and the Fire Nation is nearing victory in the war. Two years ago, my father and the men of my tribe journeyed to the Earth Kingdom to help fight against the Fire Nation, leaving me and my brother to look after our tribe.

Some people believe that the Avatar was never reborn into the Air Nomads and that the cycle is broken, but I haven't lost hope. I still believe that somehow the Avatar will return to save the world.

I've been in the Southern Water Tribe for only a few days and it felt great being among my family again. It's been a very long time since I've seen my cousins Katara and Sokka or my Grandmother. I was disappointed that my uncle wasn't here, but he's off in the war so I understood. Things have changed a lot since the last time I visited. The men are gone and the village is a lot less lively. Everyone is so serious about the war and training to be warriors. I thought about if I ever had a child, I would do anything to protect them from the war. I was angry at Sokka for trying to train the children to become fighters, what if they got killed? I pushed the anger from my mind and finished helping Gram with the breakfast of the morning for the entire tribe. That's another part I loved about the Southern Water Tribe, everyone looked out for everyone.

Katara and Sokka brought back a strange boy last night after their fishing trip on an even stranger creature. I admit, I was fascinated by the boy and his animal but since he was asleep I wouldn't bother him. There was something about him that was spiritual, I could sense it. The arrow on his head was strange, I didn't recognize it from any of the places I'd been.

"Sienna-" I heard my younger cousin shout from outside the ice tent I was in. "-come meet Aang!" I smiled before running out of the igloo and out into the bare harsh weather they lived in. Stepping into the crowd of villagers I had became acquainted with over the past few days I looked at the boy that my cousin was with closer. Yeah, he was defiantly weird looking.

"Aang, this is the entire village. Entire village, Aang." Katara introduced the boy as he bowed to us all. I noticed how some of the villagers, actually most of them, backed away from the stranger.

"Uh... why are they all looking at me like that? Did Appa sneeze on me?" The boy began looking at himself to see if there was anything on him. My grandmother stepped forward towards the boy, and I along with her.

"Well, no one has seen an airbender in a hundred years." She informed him as I took her arm. I always worried so much about my gram. "We thought they were extinct until my granddaughter and grandson found you."

"Extinct?" I saw the devastation and confusion on the boy's face as he thought about his people.

"Aang, this is my grandmother and my cousin Sienna." Katara told Aang with a smile.

"Call my Gran Gran."

"It's an honor to meet you, Aang." I smiled at the bald boy. The rest of the conversation I zoned out on, I tend to do that a lot. This boy was an airbender, but they haven't been seen in a hundred years. He couldn't be… I shook my head at a stupid thought. There was no way this kid could be the avatar, someone who disappeared over a hundred years ago.

"Sienna?" Sokka questioned, waving his hand across my face. Blinking a few times, I snapped out of my daze and blushed.

"Shut up Sokka."

A little while later I watched Sokka training some young boys how to fight. It made me sad and scared at the same time. These kids would have to grow up and fight for their lives, some of them wouldn't make it. The thought of losing a child was something I couldn't even begin to comprehend. These mothers, these wives would lose husbands or bothers or children to this awful war, and what could I do? What could any of us do but wait for us to be next?

Hearing an explosion I looked to the sky and saw a flare shoot up to the sky. My breath caught in my throat, remembering the stories Katara told me about booby-traps the fire nation set up around the area. What if someone saw it? Everyone could be in danger.

Sokka kept pacing, and it took everything in me not to smack him and tell him to stop. We waited, and waited, and waited until Aang and Katara finally got back. Relief immediately washed over me as I ran to my cousin and embraced her and Aang. Thank goodness they were safe.

"I knew it! You signaled the Fire Navy with that flare! You're leading them straight to us, aren't you?" Sokka accused, pointing his finger at Aang. My nostrils flared in anger as I stared at him. Was he really serious?

"Aang didn't do anything. It was an accident." Katara defended herself and Aang.

"Yeah, we were on the ship and there was this booby trap and well…" Aang put his hand on his head, as if thinking of what to say. "…we boobied right into it."

Gran Gran stepped forward, shaking her head in disappointment at the children. "Katara, you shouldn't have gone on that ship. Now we could all be in danger!" I couldn't help but agree with Gram, Katara should have known better than to go there.

"Don't blame Katara! I brought her there." He looked down guiltily. "It's my fault."

"Aha! The traitor confesses! Warriors, away from the enemy!" Sokka herded the children away from Aang and I felt pity for the airbender. "The foreigner is banned from our village!"

"Stop it Sokka." I stepped forward, finally saying something. "Aang hasn't been a threat to our village and he isn't trying to signal the fire nation!" I could feel my anger rising, which was something that didn't happen often but I hate it when people try to blame others for things that are out of control. "If anything it's Katara's fault. She knew not to go there and she did anyway."

"It's not my fault!" She shouted at me, her face twisting up in anger. "What would you know anyway? You weren't here when the fire nation invaded our home, you don't even belong here!" Ouch, man when did Katara get so cold?

"Katara you went too far!" Sokka yelled back at her. I was thankful that he defended me but I didn't want to cause more of an argument. "Apologize to Sienna, now."

"Enough!" Gram scolded, causing all three of us to shut up and look at her. I had never heard Gram yell, let alone at us. "Stop acting like children, you're all going to be adults in a few years and I suggest you begin acting like it. Katara, apologize to Sienna and Sienna apologize to Katara."

"I'm sorry Katara." My head lowered in shame for what I said to my cousin. "It was an accident and I shouldn't have blamed you for what happened." Holding my breath I looked up to see her face… not even looking at me. Her head was turned to the side and she was staring out at the ocean.

"If Aang is banished then I'm banished too!" Katara shouted suddenly, grabbing the airbender's shoulder and dragged him away from us. "C'mon, Aang, let's go!"

Both Sokka and I took a step towards Katara, but Sokka was the one to speak first. "Where do you think you're going?" He pointed at his younger sister as she neared the airbender's bison.

"To find a waterbender!" she growled hotly. "Aang is taking me to the North Pole!"

Aang looked at her, first confused but then his expression brightened. "I am? Great!"

"Katara!" Sokka shouted at his sister in disbelief. She stopped walking to listen to her older brother. "Would you really choose him over your tribe, your own family?" I could sense the doubt as she stood there obviously unsure what to do. Aang walked up beside her with a guilty look on his face.

"Katara, I don't want to come between you and your family." I knew he was a good kid and that just convinced me beyond a doubt he was. The airbender turned towards his bison, his expression sullen. "It was nice meeting everyone."

"Let's see your bison fly now, air boy." I smacked Sokka for being so mean to the boy. He looked at me with a bewildered expression and rubbed his shoulder sorely. "That hurt" he muttered lowly to me.

"Come on, Appa, you can do it!" he encouraged the bison. "Yip! Yip!" The animal grumbled loudly and got to its feet and began to walk off. I smiled at the boy as he exited the outskirts of the village.

"Yeah, I thought so." I rolled my eyes at my older cousin and turned around to continue with my chores.

"You happy now? There goes my one chance of becoming a waterbender!" I heard Katara snap at our Gram, causing my blood boil. How dare Katara speak to her like that?

"Shut up Katara." I snarled, walking back towards her. "Don't be angry at Gram because you and Aang got into trouble, it's your fault. Take some responsibility for once. I told you I would teach you waterbending but you won't learn from me." I could see the anger in her eyes as she opened her mouth to speak again, but I cut her off. "You don't have an excuse just because your mother died, that you're the only one who's suffered. Wake up Katara, the whole worlds been suffering long before we were here." I turned and heeled off towards one of the huts to finish weaving the basket I would use to store fresh fish in.

I sat weaving for awhile, almost completing my basket until I heard a scream and I immediately dropped what I was doing. Standing up I lifted my hand to move away the pelt that covered the doorway when an enormous tremor shook the ground and I nearly fell over. I ran outside just in time to see Sokka standing on the "tower" that he built out of snow. A huge ship was coming right at him and he wasn't moving.

"Sokka, get out of the way!" Katara yelled.

"Run you idiot!" I screamed at him in horror. The ship reached the wall and barged though, pushing the snow and ice back towards the village in a big heap. Steam came up where the ship had broken through the ice. Sokka looked up at the massive ship and drew a large breath. I took a step forward, probably being the only one who could put up a decent fight against the invaders.

With a loud noise the bowsprit of the ship opened and fell down onto the snow below it, nearly crushing Sokka like an ant. A thick layer of smoke which had collect at the top began to disperse and you could see the group of fire nation soldiers coming down the slope.

Sokka, who I dearly love but sometimes lacks common sense, hops up and charges at the firebenders with a loud war cry. The leader merely kicks Sokka's weapon from his hands and kicks him in the face, sending him sprawling into the ice planks onto the right of them. He kept walking towards the group of villagers who stood behind me. My black bangs blew in my eyes and I threw my braded pony tail across my shoulder and it fell down my chest. My deep, royal blue eyes were on high alert as the firebenders got closer.

"Get out of here." I snarled, holding my hands up and getting into a traditional waterbender stance. I watched as the leader lit up his hand and threw the fire at me. As the village gasped in horror I lifted some snow and melted it into water, easily getting rid of the fire. To my surprise the boy, who couldn't be much older than me, smirked.

If he wanted a fight, I'd give him a fight.

A/N: Well that's it for now, tell me what you think! Hopefully I can get the next chapter out soon, but I've been so busy with work and other stuff that we'll have to see. Thanks so much for reading! Remember, R&R please please please!
