A/N: Alright, so this is my Legend of Korra/Assassin's Creed 3 crossover fic. I have mentioned doing something like this for a while now and I'm finally going through with it. Do not worry, I will update my other stories as well, I am far from done with those. I just really wanted to plug some of the AC goodness into the Avatar world. This is going to be mainly AC3 oriented, but the other Assassins will be mentioned.

I hope you enjoy!

The chamber of statues was silent as ever.

Korra never truly got to experience this room in the Avatar temple of the Southern Tribe. She never wanted to nor needed to when she was here and her training was always in the compound.

Going slowly, she limped among the past Avatars, staring back at their blank faces. While she was out of the wheelchair now, her body was still weak and her nightmares made it hard to sleep.

That was why she was here now. Amon, Unalaq, and Zaheer were torturing her dreams again and she didn't want to see them. Without thinking, she came to this hall. Seeing the former Avatars' blank stares actually helped. They didn't have the continuously sympathetic or judging look that she had been seeing way too frequently.

They just stared straight ahead, looking more wise and powerful than she ever could.

When she was on one of the balconies in the huge cave, one Avatar in particular made her halt in her tracks. She craned her neck to look up at him and her mouth dropped a little at the sheer size of the statue. He had to be one of the tallest Avatars there. His Water Tribe robes gave him a familiar look and his pointed hood almost covered his eyes.

"That would be Avatar Sitka."

Korra jumped and turned to see one of the Temple scribes standing nearby.

"He was one of the most influential Avatars for our tribe. He was the reason why the Southern Tribe separated from the Northern Tribe and he helped them create their Sisterhood," she explained, stepping closer to the Avatar.

Korra's eyes widened and she looked up at the statue again. "I never knew an Avatar was behind the Northern and Southern tribes. I always thought it was just something that happened."

"Yes, and he almost died while doing so. They say he disappeared during a battle while doing the Avatar state and they thought-"

Flashes of fighting back the Avatar state and the pain involved in doing so caused Korra to stiffen. "That's alright, thank you though," Korra interrupted, looking away. "I need to be alone right now, if that's okay."

"Of course," the scribe turned to leave and then paused before doing so, looking over her shoulder, "we all think you are strong, Avatar Korra. I just wanted you to know that."

Korra knew she meant well, but she didn't want to talk to anyone at the moment. She just gave the woman a weak smile and a nod before looking back up at the Avatar in front of her as she walked away.

"It almost happened to you too, huh?" she grumbled, staring up at the Avatar's face.

Avatar Sitka didn't respond; he just stared blankly ahead.

Avatar Sitka never left her mind after that night.

How many Avatars have gone through what she had gone through? How many had thought they would be the last Avatar to ever exist? How many had thought they had let the whole world down?

Korra had to know. She had to know if they felt the same way she did.

Aang obviously almost died in the Avatar State too, but she needed to talk to someone else. She needed to see a new face, and Avatar Sitka was the only other one she knew of. Yes, she didn't have the connection to the Avatars anymore, but if she could talk to Iroh in the spirit world, why couldn't she talk to them?

She stumbled toward the temple, trying to not make a sound in the night. She didn't want anyone knowing she was there. Her body cried out and protested with every step, but Korra knew that she needed this. She knew she was far from okay, but this could be a start to getting there.

The temple finally came into view and she stumbled inside. She opened the little hatch in the floor that led to the cave underneath. She reached the large cave and started to hobble her way toward Sitka's statue. She plopped down, breathing heavily and wincing in pain. "You better be worth it," she grumbled to the statue.

Her joints clicked and groaned as she slowly got herself into the lotus position.

She evened out her breathing and all of her pain and discomfort left as she entered the spirit world.

Her eyes opened to see a vast, familiar looking tundra. Many blue, white, and silver spirits glided by, not even looking toward her. Hundreds of spirits were floating in the lights above.

"Where are you all going?" she mumbled aloud. She stepped forward, grinning a little when she didn't feel any pain in her muscles from the movement.

One large, wolf spirit stopped next to her, fixing her with its cool, blue gaze. It was almost Naga's size and its white and silver pelt gleamed under the flashing lights in the sky. It nudged her shoulder before leaning down. Korra grinned and leapt up on its back. She missed doing this with Naga, and being with the wolf made her think about her best friend even more.

The wolf started raced forward through the snow. Korra leaned forward and clutched at the fur around its neck. "Take me to Sitka," she whispered.

She didn't know how long the wolf ran along, nor did she care. The boulders and glaciers passed by in blurs. The lights above sparkled throughout the sky, their green, blue, and pink lights caused the snow to shine.

The wolf finally slowed to a stop when the ocean came into Korra's view. Korra sat up as it started to lazily walk along. She scanned the horizon, looking for anything or anyone familiar. A large figure near the shore line caught her eye.

She hopped off of the wolf, giving it a small grin and a pat on the head. It nudged her shoulder again and started to run toward the figure, barking as it went.

Korra started to sprint after it, inwardly shouting with joy at the fact that she could do that here.

The wolf leaped forward and tackled the figure, and Korra heard a deep, soft laugh come from him. "Easy Ila."

Korra slowed down and slowly made her way toward the man. The height alone gave the man's identity away. And even in the spirit world, he wore the distinct hood she recognized from his statue.

"It has been a long time since I have seen another Avatar from my tribe," he suddenly said, ruffling the fur around the wolf's neck.

"Uh, you're the first one I've met. I'm Korra," Korra declared, stepping even closer.

"I know. I have heard a great deal about you," he replied, pulling back his hood.

Korra's eyes met eyes that were so dark blue, they looked almost black. His hair was halfway pulled back into a wolf tail, letting the rest hang down around his neck. Two, thin braids rested on the right side of his face. A thin scar ran through his left eyebrow.

"Now, may I ask why you are seeking out an Avatar that lived thousands of years before your time?" he asked with a wry grin, beckoning as he walked along the shore.

Korra bit her lip before following him. She jogged to catch up with his long stride and fell into step beside him, still trying to put what she wanted to say into words. "I was told that we might have had…a similar experience."

Sitka let out a low sigh. "And that would be?"

"Did you almost die in the Avatar state?"

The tall man stopped and stared out at the ocean. "Yes, I almost did."

"How did it happen? How have you coped with that?! I almost ended the Avatar line twice for being stupid!"

Sitka's intense gaze zeroed in on her and Korra immediately wished she didn't say anything. For once, someone wasn't looking at her with pity or sympathy when she said that and it was oddly refreshing.

His eyes were as hard as stone and his mouth had set in a firm line. "You did it to protect a new nation. You selflessly sacrificed yourself for the greater good and doing your duty. I was being stupid and getting revenge when it happened to me," he finally admitted.

Korra opened her mouth to argue, but stopped when he held up a hand. "I will gladly tell you my story, and tell you how I coped with the guilt of almost putting Raava's life in danger."

"Wait, you were still close to Raava?"

The corners of Sitka's mouth slowly turned up into a grin. "Yes, I was one of the few that were able to speak to her in choice times. Most Avatars never get that privilege."

He beckoned to her again and kept moving. Korra followed him until they stopped at a cove. Sitka picked up a rock and skipped it along the water. "To understand how I almost ended Raava's life, you have to know my whole story. I will begin when I was five…when my mother died."

The shouts and yells of men could be heard all along the bank of the river.

Three tiny heads peered over the edge of the large glacier, daring to get a peek at the strange people coming to the shore.

"Are those the Northern men mother spoke of?" one little voice squeaked.

One little boy with shaggy, dark brown hair narrowed his eyes toward the outsiders. More and more Northern waterbenders kept coming to their home. And he didn't like it. This was their home. Why did those men think they could just live here as if it was their own?

The little boy kept asking himself these questions as the last of the boats came to the beach.

His mama told him the various waterbending tribes of the South Pole were always that. Just tribes. There were tribes like his, which lived in a valley near the mountains, or tribes that lived on the coast. They traded with each other and the only conflicts they truly had were about how much each tribe should have.

Then, waterbenders from the North decided that their way was not right. Mama told him that those men have been coming here since she was a little girl and that the Northerners helped certain tribes fight against others, getting land of their own in the process.

Mama told him his Papa was a Northerner, but he wasn't allowed to tell anyone.

He wondered if his Papa was down there as he narrowed his eyes at the men on the bank. His Mama said that he should be at this pole still.

A tug on his sleeve caused him to look at his friend, Ukik. "Sitka, we must go before we get in trouble!"

"Yes, our mamas will kill us if they find out," Arnaq, his other friend hissed, her eyes wide.

Sitka rolled his eyes, but followed anyway.

They hurried back home and Sitka was able to show them a trick his mama taught him to get home faster. They all were waterbenders, but they still had much to learn. Sitka's mama was able to teach him how to glide over the snow and ice by using his bending, and it came in handy in times like this.

Soon enough, they were able to see the various huts and igloos of their village as they zigzagged through the bare trees of the forest in the valley.

Sitka immediately ran to his hut, waving goodbye to his friends as he went. They were supposed to be back from playing before sundown and the sun was almost completely below the horizon. Sitka opened his door as slow as he could before shutting it behind him.

Sitka loved his Mama, but that didn't mean he wasn't scared when she was so angry that she was quiet. She was squatting by the fire in the middle of their hut. The way he could tell she was angry was from how she had her lips in a thin, angry line. The stew she was bending in the pot in front of her was swirling furiously as she waited for the stones to warm up.

Sitka's mama was the prettiest woman in the world when she wasn't furious. Her face was long with pretty eyes and a warm smile and her two braids were really long, almost down to her waist.

That was when Sitka liked his Mama the best, when she was smiling.

Now, he just looked down at his little feet and hoped that she wasn't too mad.

His friends went as far as calling his mama 'Atka the she-bear' when she was angry for a good reason.

She gestured to the spot across from her at the fire. "Sit."

Sitka slowly shuffled over and sat down, drawing his knees up and wrapping his arms around them. He buried his face in his knees to avoid looking at her.

"You know why I'm angry?"

"Yes."

"And how many times have I told you to not do this?"

"Many."

"Are you sorry?"

"Yes."

"Sitka, look at me."

Sitka finally raised his head and looked at his mama. Atka's eyes stared at him like hardened flint for a few moments before she finally let out a long sigh. "Child, remember that I make rules for reasons. There are people and things out there that will not hesitate to hurt a little pup like you. Do not take chances with your life."

She stopped bending the stew and pointed at him. "I am going to let you off this time, Sitka, and that is because I am in a good mood."

Tui and La must have been overly watchful over Sitka that day.

"Now, go get cleaned up."

Sitka nodded and walked out the door, skipping toward the river. He liked his home the best because they were not that far from the river. All he had to do was run about 60 feet and he was there.

He immediately knew something was wrong when he made it to the bank of the river. It was quiet. None of the animals that were out and about during the summer were anywhere to be seen and even the river seemed to be silent.

A heavy crunch in the snow was his only warning as big hands grabbed the collar of his coat and threw him down. The breath was knocked out of Sitka's lungs as he fell to the ground and he couldn't even call out for help.

The big hands grabbed him again and pinned up against the nearest tree. Sitka finally opened his eyes and they widened at what he saw. A Northern man was holding him up by the collar of his coat and sneering at him. A man in a green coat and heavy boots crossed his arms with a grim look. A man in red robes was looking around nearby and another man in yellow and orange robes was rolling his eyes with a yawn.

"Tell us where your elder's are, and we'll let you go," the man holding him ordered, giving him a fake smile.

Sitka remembered the two main rules his mama always gave him. Never talk to strangers and never reveal anything about your tribe. His little heart was threatening to fly out of his chest as the man's grip on his collar tightened in warning. But there was only one thing he could do.

Instead of answering, Sitka spat at the man's face. The big glob of saliva landed in the man's dark beard.

His lips instantly turned down into a frown as he bent it away. "Now, that wasn't very nice."

"Sitka?"

Sitka looked to the side and he never was so happy to see his mama.

Atka stood just outside their hut and she was looking down the hill furiously at them. The man was barely able to block her first attack.

Sitka was dropped in an unceremonious heap and he quickly started to scramble up the hill toward his mama.

"Get the brat!"

"Stop her!"

Atka and the northern man were now furiously throwing spikes of ice and water toward each other. Sitka yelped when the ground underneath him started to move. He looked and saw the man wearing green robes standing in a strange stance.

The snow on top of the ground suddenly turned to water and wrapped around him. Sitka shouted in shock as he was tossed up the hill before the ground moved more.

Sitka landed next to his mother, staring up at her in reverence and fear as she skillfully moved into the octopus stance. She was defending off blocks of earth, spikes of ice, and fire. The yellow robed man was nowhere to be seen.

"Sitka, little cub, you must warn the others. Go!"

Sitka opened his mouth to argue. Even he knew that his mama was outnumbered.

"Go!"

Sitka quickly scrambled to his feet and started to swiftly glide over the ice.

"I love you!" she shouted.

Sitka tried to hold back tears as he made his way toward the Chief's hut.

"What happened?" Korra quietly asked.

The two Avatars had settled on top of a large boulder next to the sea. The celestial water would occasionally splash up onto them, but neither moved.

"She did not survive…neither did half of the village. The firebender set all of the huts on fire and the waterbender and earthbender destroyed everything else. That was the last time I saw her alive and I was proud to call her my mother." Sitka looked up at the sky with a sad smile. "I tried to not be bitter after her death, I knew she wouldn't have wanted me to."

"Did she know you were the Avatar?"

Sitka shook his head. "No, I did not know I was the Avatar until I was sixteen years old. It was a good thing those men did not know, either. They killed the Avatar before me."

Korra's eyes widened in shock. "What?!"

"Those men were members of an ancient group called the Niyama. They wanted to create a world where everyone was under their control. The Avatar was the representation of the exact opposite, which is freedom and peace. The Niyama wanted peace as well, but with no freedom," Sitka explained. "My father was one of the leaders of that group and that was why my mother refused to be with him. To everyone else, he was one of the best generals the Northern Tribe had and he helped my tribe win many battles. The North took our land by the coast as repayment. My mother and father fought side by side during that conflict."

"So when your dad wasn't being a general he was a leader of a group that wanted to take over the world? Where have I heard that before?" Korra clarified bitterly, thinking of Unalaq.

Sitka patted her on the shoulder before taking a deep breath. "That is one of the trials of being the Avatar, even the ones closest to you will be capable of using you to make their goals a reality. My father traveled to the Southern Air Temple shortly after my mother left him and he and his group attacked Avatar Malai. She was too old to fight and she told me she sacrificed herself so that the next Avatar could be born and help stop them."

"How can someone stop a group like that alone?! The Red Lotus are still out there and I don't have a chance alone!"

"I wasn't alone when I stopped them."

Korra stared at him in shock. He had to deal with something she has to deal with. Maybe, just maybe, he could help. "Who helped you?"

"A group that had fought against the Niyama for thousands of years before my time. They were called the Heiwa and they were my greatest allies in my fight against the Northern Tribe and the Niyama."

"How did they help?"

Instead of answering right away, he looked out toward the ocean again and continued, "There had been grumblings about the North having too much power as I grew up after that. We rebuilt our village and for the most part we lived in peace, but I could not accept the fact that what happened will not happen again."

He sighed heavily and looked at her. "I was fourteen when I found out about the Heiwa, and I was determined to join them."

"We must protect our village! Not just stand by and watch the North take over!"

"There is a man that can help you, my boy. Follow the river. You will find a shack near the top of the falls."

The chief's words were still echoing in Sitka's ears as he hitched his pack up higher on his shoulders. The fourteen year old boy pulled his hood down more and continued up the river. The surge of the water gliding beneath his makeshift ice-board was as thrilling as ever, but the thrill almost covered up the grim feeling inside of him.

After his mother's death, Sitka was determined to become the best warrior he could be. Even after learning everything from his village's masters, he needed to learn more. He did a lot on his own, but it wasn't enough.

That was when the chief mentioned a man who used to live in the tribe, and this man was the one who trained his mother.

Sitka came to the realization that this wasn't entirely his choice as he went further up the river. After all that has happened to his village and the South, he felt that this was almost an obligation. He had to do something.

Anything.

The incline of the river was starting to make gliding against the current almost impossible so Sitka propelled himself toward the shore instead. The roar of a waterfall could be heard and Sitka knew he was close as he jogged along the shore.

Chief Akiak told him the old man lived at the field near the top of the waterfall, and Sitka could see a thin line of smoke coming from the top of the cliff. Sitka looked at the water crashing down the falls and he grinned at the challenge. He took a deep breath before sprinting toward the waterfall. Leaping up, he bent the water around him and used the massive amount of water from the falls to propel him upwards.

The masters at the village were always impressed by the sheer amount of water he could bend at a time, they usually gave his tall, broad stature the credit.

Sitka finally reached the top and he landed on the shore next to the falls. The sight before him was amazing and it caused him to let out a small gasp.

Nature was always beautiful to Sitka, and this place was one of the reasons why it was.

The waterfall he just went up was nothing compared to the water fall that was crashing down the cliff about 500 feet away from the first one. The side of the mountain loomed in front of him and curled around the two waterfalls, showing how the water eroded at the rock over time.

He turned in a circle, taking in the sight around him. The few bare trees and bushes nearby started to make him imagine what this place looked like in the summer, when things could actually grow.

Sitka finally noticed the decent sized hut near the cliff wall and he slowly loped toward it. His heart started to thud in his chest at the thought of meeting the man. His mother always spoke highly of the old waterbending master.

Master Nanuq was supposedly the best waterbender his village had ever produced and Sitka had no idea how to ask this man to train him. While Sitka was good at many things, like hunting, waterbending, and building, talking to people was never on that list. He hated talking to people and would rather not do so if he didn't have to.

He halted in front of the door and took a deep breath before raising his hand and knocking.

The door opened and a weathered, white haired man frowned at him. "What?"

"Uh, I was told you could train me."

"No."

The door abruptly shut in Sitka's face.

Irritation started to bubble in Sitka's gut. He pounded on the door and his only reply was a, "Go away!"

"I'm not leaving!"

"Fine, then stand out there."

Sitka sighed and said the only other thing he could think of that could work. "I'm Atka's son."

The door suddenly burst open and the old man stepped over the threshold, staring at Sitka's face intently. Sitka glared back, refusing to back down.

"Tui and La, you are. Get in," he grumbled, his mouth turning down into an even bigger frown.

Sitka quickly stepped in before the man could change his mind.

"Sit."

Sitka sat on the furs in front of the fire. The old master sat down across from him, crossing his legs. "Now, why did Atka's son bother with the 5 hour journey to get up here? Let me guess," he paused with a wry smirk, "You think you're the best waterbender out there and you ran out of teachers so you decided to bother an old man?"

While part of it was true, Sitka refused to let this old man ridicule him. "I do not think I am the best, but I want to be. I have to be in order to protect the village and stop what's happening."

"So you came to old crazy Nanuq to learn. And, by the spirits, what is happening?"

"The North is trying to take over the South, someone has to stop it."

Master Nanuq waved a dismissive hand. "That's the Avatar's job."

"But the Avatar hasn't been seen in over 10 years! If she can't stop it, we have to."

The teasing glint in the old man's dark eyes turned into a serious one. "What makes you think that Avatar Malai is still alive? What if the new Avatar is training in the North as we speak?"

Sitka clenched his fists. That was impossible; the Avatar would never support theft and domination. "They surely wouldn't help the North right?! They have to be above that!"

Master Nanuq shrugged. "If so, what can you do? You're a boy who knows nothing about the world."

Sitka grit his teeth. "Someone has to do it."

Master Nanuq stroked his long beard for a moment before letting out a long sigh. "Get comfortable, boy. I have a long story to tell you."

Sitka shifted his legs a little with a frown. What was the old man talking about?

"About two thousand years ago, a secret society rose up among the nations. This group called themselves the Niyama. They believed that peace can only be obtained through control and order. They started to insert themselves into every major society of the time. They soon came into leadership positions and started to plot against the Avatar. The Avatar represented a type of peace they feared and hated. So, naturally, they tried to kill the Avatar of the time, Avatar Suchin."

Sitka's eyes widened and his stomach rolled as a weird feeling of nostalgia came over him. Why did he feel like he knew this story?

"Avatar Suchin realized she would never be able to defeat this group on her own, so she recruited people and trained them to specifically fight against the Niyama. This group is known as the Heiwa." Master Nanuq coughed a little before continuing. "Avatar Suchin gave this group three rules she knew the Niyama would never be able to truly follow. They were: Never harm an innocent, use stealth at all times, and never compromise the Heiwa."

Again, Sitka felt as if he heard the words before, but he couldn't quite think of when he would have.

"The Heiwa learned a new style of fighting taught by Avatar Suchin. Her husband also contributed by teaching them how to fight without bending and by making them weapons that could easily be disguised as bracers on their arms. Avatar Suchin refused to be their leader, since she came from the Nomads, and she appointed their own. Suchin created her own ally against the Niyama, and they have been fighting to keep the peace ever since, aiding the Avatar when they can."

Master Nunuq stared straight into Sitka's eyes. "Do you understand what I'm telling you boy? I belong to the Heiwa and I have served them most of my life. Your mother knew of them as well. Did she ever tell you why she left your father?"

Sitka stiffened. His mother never truly told him much of his father. He only knew that he was a Northern general and that he was a skilled waterbender. "Why did she leave him?"

Master Nunuq sighed heavily, looking up at the ceiling. "Your father, Tulok, is the leader of the Niyama in the North and South poles."

The information seemed to suck the air right out of Sitka's lungs. How could his mother ever want to be with someone who wanted to control everyone?

It all made sense now, despite that.

"Are the Niyama behind what has been going on between the tribes here and the North?"

"If I told you that they have had a significant influence, what would you say?"

Sitka stood up and started to pace. "I would say that it is wrong and they should let the people of the world decide their own fate, no matter where it is. I want to stop it."

Master Nunuq slowly pushed himself to his feet. "Well then, boy, do you want to train to become a brother of the Heiwa and help make that a reality? Keep in mind that we must help and serve the Avatar as well. Would you be alright with working with someone from the North if the Avatar is from there?"

Sitka thought about it for a moment. Would he be willing to side with someone from the North? The Avatar was supposed to not have too much bias in all conflicts. Maybe this group could convince the Avatar to help. If the Avatar helped, Sitka's village could stay safe.

"Yes, I can. I want to join the brotherhood."

Master Nunuq grinned. "Well then, set your pack down. We start immediately."
