I don't own TLA.

They all looked at me like I was crazy, but when I pulled out my amulet with the Air sign, Aang gasped.

"It is from the Southern Air Temple!"

"She stole it," Zuko rationalized instantly.

"No. It was given to me by Monk Gyatso before the Fire Nation attacked," I shot back, now allowing my fire to color my voice. He was beginning to get on my nerves.

"But you can't be the Avatar. Aang's the Avatar," Katara pointed out, her voice a lot calmer than Zuko's.

"I never understood it either, but I am also the Avatar, yet it's different for me. Besides all four elements, I can also bend spirit, which is how I healed you. It's a more advanced form of Energybending," I explained, knowing that she probably wouldn't understand completely.

"How could you have survived? You weren't trapped in an iceberg like Aang," Zuko challenged, his voice practically daring me to answer.

With the same edge to my voice, I responded, "It's part of the Spiritbending I mentioned earlier. I am immortal. I cannot die unless someone kills me, and so far it hasn't happened." He clearly didn't believe me, so I sighed in irritation and asked, "Do you want a demonstration then?"

"Sure."

We all looked at Aang, who hadn't spoken since I pulled out my amulet, which I had tucked safely back into my shirt. I signaled to follow and, pushing past Zuko, brought them straight to the garden in which I had slept in this very morning.

The water reflected back the sun warmly as I approached the pond that I had been looking at the night before. Who would have thought so much could change in such a short time? Not only had I met Aang after a hundred years of waiting, but I was about to show him who I truly was. It was breathtaking to say the least. That and I get to show up an arrogant know-it-all. That's always fun!

As I waited until I was sure I had all of their attention, I took a deep breath to steady myself. My calm was shattered a moment later.

"Well get on with it then!"

Zuko's voice instantly fanned the fire burning in my stomach, and I brought myself up in an air bubble, my cloak billowing out behind me but never revealing my eyes. Then I called up a ribbon of water, making it form a thick flowing ring around me. Fire was next, which was easy enough seeing that I could just call it into being. Earth was slightly more complicated because I didn't want to disturb the garden, but eventually I found some loose rocks to use and called those up as well. I stayed hovering there for a few moments, basking in the elemental power surrounding me.

Finally, though, one by one, I released the elements and lowered myself back to the ground. When I looked up, I allowed my hood to fall back, showing off my silver eyes for the first time since I came. They were all staring in awe—even Zuko.

"As you can see, I am clearly the Avatar. And Aang?" His hazel eyes locked with mine. "I'm your twin sister."

He was shaking his head in denial, and I really couldn't blame him. We were separated at birth, so how would he have ever known about me?

"I know it's hard to accept, but I speak the truth. Come. I will show you," I invited, holding my hand out, palm up. An invitation. Our eyes remained locked, his being a watered down version of my own. Slowly, slowly, he came forward and took it, gasping as the visions I've seen multiple times flooded him.

Mother lay gasping as the vision faded. Twins. She was having twins, and in order for them to fulfill their destinies, she would have to give the girl up. The nurse came in then, a look of concern passing her features when she saw Mother's sweat sheened face. When she came over to feel for Mother's temperature, she grasped the nurse's hand, a desperate look in her eyes.

"You must take the girl! You must! Please!" she begged, her voice hoarse with desperation.

"What do you mean? Why?" The nurse was very confused as she tried to calm Mother, to no avail.

"Please. You have to trust me. You have to take her!" Mother continued to beg. Finally the nurse conceded, agreeing to the take the female child despite her obvious reluctance and confusion.

Father beamed as he held his son for the first time.

"Little Aang," he murmured as the infant grasped his finger.

"Go on dear. Go to Gyatso and show him our new son," Mother said, trying to keep her voice as steady as possible, though contractions still pulsed through her.

Father nodded, gave her a kiss, and left, enabling her to give birth to me. I didn't cry like Aang had. Instead I opened my eyes and looked straight at the nurse holding me, earning a gasp as she saw my silver eyes.

"Take care of her. Please," Mother panted, now completely exhausted. The nurse was trembling, unnerved by my intense gaze. "Please." Finally she nodded, wrapping me up and taking me to the home I knew for twelve years.

I was only two, and already I had mastered Airbending. My foster mother was incredibly surprised and proud, so much so that she brought me to Monk Gyatso and asked if he could teach me. He gladly agreed as I reached up to touch his amulet, my eyes wide and admiring as I traced the swirls of the Air symbol.

"Maybe one day you will make one of your own," he told me. I looked up at him with my wide silver eyes and smiled.

Three years passed. I was now five and beginning to experiment with my bending. One day while watching the clouds lazily drift by, I decided to pretend to be a Waterbender, so I got up and began to twirl around, moving my arms in fluid movements as if it were my native element. I was only playing, so you can imagine my surprise when I actually drew the dew from the clouds, forming a globe of water in front of me. Once my surprise passed all I felt was fear. I shouldn't be able to bend water—I was an Airbender! I released the water and ran all the way back home, vowing never to tell anyone of my experience with the cloud.

Of course, being a naturally curious child, it didn't take me long to get over my fear and try my experiment again, with the same result. If I could do this with water, then what was stopping me from bending fire? Or earth? I decided to try fire next, startling myself when the orange flame jumped from my small clenched fist. I stared at my unburned hand in amazement, a slow smile creeping onto my face. I clenched my fist again, steadied my stance, and stomped on the ground, causing a large chunk to detach and float up. Then I punched it, shattering the boulder into tiny pieces. A peal of laughter danced on my lips. From that day on, I began to apply my air lessons to my other bending, mastering those by the age of six.

Now I was about nine and roaming the temples, occasionally pausing to play with another child before moving on. Eventually I made it to where I was going, finding Gyatso meditating in the middle of the pavilion.

"Monk Gyatso," I greeted him, bowing in respect.

"Ah Sorami. You are early," he replied standing.

"I'm sorry." I hung my head, thinking I had done something wrong. Usually I didn't interrupt his meditating, but today I had.

"Keep your chin up, my child. There is no need to hide those eyes." He tilted my chin up. "Do not hide your eyes in shame. Only in respect."

I nodded to show I understood, my guilt dissipating, and we began my lesson.

Ash fell from the sky as the ships steadily grew closer. I was standing at the edge of the cliff, the entrance to the temple, preparing to defend my home when Gyatso came up behind me.

"Go Sorami. You need to fulfill your purpose, and dying in this fight is not it," he said handing me my glider.

"But Monk Gyatso! The temple will be destroyed!" I protested pointing to the ships.

"Do not worry child. We will be fine. You must go." He handed me an amulet similar to his but smaller then and watched as I jumped from the cliff.

Right when I got out of range, the fireballs began to rain down, creating destruction in my once peaceful home. Tears blurred my vision as I flew, but fly I must. Flying was living, and I couldn't let Monk Gyatso down.

As I grew, my Spiritbending grew stronger as well. I learned many things about it, such as immortality and age appearance control, partial and total Spirit body, healing, and defense, which I tried to avoid using as much as possible. I learned about the body, Chi and Chi blocking, the Chakras, the aura, and how to use seismic sense. I had met my animal guide, though she mostly stays in Spirit form. I had learned of my true mother, her vision, and how my brother was the Avatar. I learned to wield weapons, such as the bow and arrow, multiple types of swords, such as double broadswords, a single sword, knives, a katana, and a Jian sword, my staff, which I had remade to shrink and attach to my back for practical and stealth purposes, throwing stars and stilettos, bolas, spears, shanzi (the fans used by the Kyoshi Warriors, whom I had met for a brief period of time during the early years of the war), and my own hands. My features had become hard, detached, emotionless, the product of many difficult years of running or fighting. Hope was just a story to keep the cold night a little warmer. I was ready to give up but unable to, for I also traveled and provided healing services, not to mention that I was immortal. And then there were the spirit attacks that could cripple me for days at a time. They got worse and more frequent the longer the war went on. Then Aang returned.

Years had passed. I was flying when the energy wave nearly knocked me from the sky. Tears of joy streaked down my cheeks, forcing me to land. He was back. He really was alive. This war would finally end!

Seeing him for the first time since the attack was like a dream. It took me a long time to find him, but finally I had. He was surfing an elephant koi. I wanted to join him, to reveal myself, but the Spirit World wouldn't allow me to. It would interfere with his destiny. So I had to leave. I couldn't live with just watching. Not back then anyway. My time would come, though, and until then, I'd allow brief glimpses. Until then, I'd remain in the shadows, the watchful eye that provided any help that she was allowed. I'd be the hidden assistant, and one day, I'd be his sister once more.

Aang was caught up now. He knew everything...important anyway. And the look in his eyes was one of a blossoming sibling love, though he didn't know me –or that I existed—until this morning. All I offered was a guarded smile. I've been hurt too many times to immediately let him in, even though he was my brother. Then Katara was there next to him, her hand on his shoulder.

"What did you see?" she asked softly.

"Everything I needed to. She really is my sister guys." His voice was mystified to say the least. I was used to this, so I remained unaffected.

"So have you been following us this entire time?" Katara asked.

"Not all the time. In the beginning I couldn't be around for very long or I'd risk showing myself," I explained, knowing that she probably wouldn't understand.

"Then why did you come now?"

We all turned to look at the young Fire Lord, surprised at just how bitter his voice was.

"Because Katara was being attacked by a dark spirit and if I didn't help her she would have died," I replied bluntly.

"Right. And I suppose that fairies and goblins exist too." He rolled his eyes; I glared at him.

"You know, someday you're going to need my Spiritbending. Someday soon, and when you need it, you're going to regret doubting me," I hissed lowly, trying and failing to hide just how much he got under my skin.

He snorted. "I'll be sure to keep that in mind." And with that he stalked away, leaving me simmering.

Aang and Katara made sure I was comfortable in my new room, asking me numerous times how I was settling in during the next few days. It was still dizzying how fast things had happened. One day I was watching from the garden wall, and the next I was living in the palace with my brother. Things couldn't be better! Well…other than the young Fire Lord being slightly less hostile every time we crossed paths anyway.

Ok, so I have no clue how children were born in the Air Temples. If I didn't get it right, then sue me. I tried. Anywhoo, there was some background information for Sorami. I hope you liked it! I tried my best to keep things similar to how it happened in the movie. I hope I did all right... :3
