Okay, so here's where the action begins. Battle scenes, crazy unexplained storms, and Azula is back… what will happen?? Duh duh dun!!

3 MONTHS LATER

Aang waited for the news. He had been stretching his leg everyday, and he wanted to go home soon. He didn't even need crutches anymore, and he practiced everyday to not have a bad limp. It didn't hurt as much as he walked, but he knew that ugly scar would haunt him the rest of his life. Now, he was lying against Appa, waiting for the doctors to say that he could go home.

The doctor who had first treated Aang walked up and sat next to him. He breathed in deeply. "Son," he said on his exhale, "you—"

Aang waited.

"—can go home."

"Yes!" he cried, jumping into the air like a twelve-year-old kid again. He danced with Momo. He danced with the doctor. He danced on top of Appa, jigging all over the place until his leg throbbed again. But he just gathered his things and jumped onto Appa. "Thanks, doctor!" he said as he grabbed the reins. "Appa, yip yip!" Appa jumped and flew into the air with such energy that Aang nearly fell off.

He steered the bison to the South and flew over the outer wall. He gasped just as he saw 40,000 Fire Nation attacking 10,000 Earth Kingdom. Aang let out his breath. "We're not going home yet, guys." He flew the bison toward the earthbenders and landed on the ground. Aang grabbed his staff and stuck it in the air. "The Avatar IS BACK!"

Katara waited anxiously for Sokka and Toph's return. They had been gone for 3 months and she waited for her brother and best friend to return to see if they were going to be married. She was already 8 months pregnant, and waiting was just something she just couldn't handle anymore.

She sat down in the snow, holding her huge belly as she looked in the sky. Someone sat next to her and put a blanket around her. She turned to see her father sitting next to her. He smiled as he touched her cheek. "They'll come," he said, looking to the sky. "Sokka and Toph are in good hands with Storm. They'll come today." He looked at his daughter's belly. "You feeling okay?"

"Yea," she answered, keeping her eyes to the sky.

"You know," he started, "your mom used to sit in the snow while she was carrying you two inside of her."

"Dad, you don't have to talk about mom."

"I want to. I've been keeping it in way too long. And you should know more about your mother. I know you remember her, Katara, but I knew her far before we were married. She was my best friend. We would do everything together, and friendship blossomed into love, just like yours and Aang's, and Sokka's and Toph's. But your mother—" he laughed. "She loved to sit in the snow and watch the clouds go by," his smile faded. "When I lost her—" he closed his eyes. "I had lost almost everything. But I couldn't mourn because of you two. I held it in, but once I left, I let it out because I was fighting the Fire Nation. I fought for you and your brother, but mostly I fought through tears for your mother." Katara saw him tear up. "Oh, I miss her," he whispered, looking at the clouds. "But I see her every day in you and your brother. And she's with me." he looked at his daughter. She smiled and hugged him. "I love you dad."

I love you Katara, more than you'll ever know." He got up and gave her his hand. "Let's go in. Those clouds on the horizon mean probably the biggest storm of the year." She got up, supporting her back, as they went to his tent for some hot tea.

An hour later, they both went outside to check the storm and see if Sokka and Toph were back. The sky was black, and snow was starting to fall. "No sign of them," Katara said as she watched the clouds move steadily closer, bigger and blacker every minute. She stared at the horizon, and in the midst of the black, a speck of white was seen. She stared, until she knew it was Storm. "Dad!" she yelled. "They're back!"

Hakoda looked to where she was pointing. His smile grew wide as the eagle swiftly came in. But their smiles disappeared as the eagle was flying as fast as he could straight for them. Storm landed and Sokka looked straight at his dad. "We've got trouble."

He got off Storm, and then helped Toph off. "What's going on?" Katara said as she followed her brother, who was running to the war tent.

"Sokka!" she caught him by the arm. "What's wrong?" He turned to look at her. "Fire Nation fleet. 200 ships, coming for us."

"What do we do?"

"How should I know? You're the admiral," he said as he walked away. "Call all of the troops and warriors together now! Tell them to bring all armor and weapons. Go!"

She took off in the other direction, yelling down the rows of tents. "Attention! We are under attack! Bring all armor and weapons and meet in front of the war tent. This is not a drill!"

As warriors ran by her, she went to put on her own armor, beautifully made by her brother a few months ago; it was designed to protect her and the baby. As she grabbed her helmet and water flask, she ran out and squeezed through the crowd. Her father, brother, Toph, Zuko, Bato, and the other leaders were at the front. As she sat down, Sokka stood up and told the warriors battle plans and strategies. Then he asked for any questions, and dismissed everyone to their post. As he did, snow mixed with soot began to fall. They all looked towards the horizon and saw the first ships. They also saw the storm coming in more swiftly.

Katara stopped Sokka and Toph. She pulled them aside, and she hugged both of them. "I missed you two," she said. They hugged her back. "Sugar Queen we missed you too!"

"So," Katara said, "What's the news?"

Sokka looked at Toph, and she nodded.

"Well," he started. "We—can get married!"

Katara smiled. "Congratulations! You guys will make each other happy."

"Thanks," he said. "How's Sokka Jr?" he said, patting Katara's stomach, which was protected in armor. "Good!" she said, "getting close."

As they all walked to their posts, Toph felt the baby's vibrations. "Maybe closer than you think, Sweetness," she whispered to herself.

As Zuko put his armor on, and messenger walked up to him. "Zuko? Sorry to bother you, but I cannot find Miss Katara. Can you give her this message?" he handed it to Zuko. "Of course," he replied. "Thank you."

He opened it and read. "It's from the University!" he said to himself. He read it:

"The symptoms of the birth of an airbender: bad storm, strong gusts of wind, and a small breeze with sunshine following the birth. The child is usually born at sunset, mostly in fall, the season of the Air Nomads. As the child grows, strong breezes or the effect of airbending is felt. Then, basic moves are performed. Any more questions please contact me again, Professor Wei, head of studies of the Air Nomads."

He put it into his robe and grabbed his broadswords. He stepped out of the tent and walked to his post on the Northern Wall. As he put his helmet on, he saw the black storm moving faster. "No, not today," he said, turning his gaze to Katara, who was twenty warriors down. "Any day but today," he whispered, but then focused his attention to the ships. They had hit the ice and were unloading the first ship of the army. And he couldn't believe it. There, in the front, was his sister. Behind her were Mai and Ty Lee, and the rest of the troops. He grabbed the telescope from below him and looked at Azula. Where he burned her face and slit her throat were now only evil scars. The scar on her face from her left eye to her chin and to her ear and hairline made her look even more sinister. And the scar below her chin on her neck was just an ugly scar. He shivered, but got ready. He looked at Sokka, who was ready, and Toph, who had a few boulders in front of her, ready to attack.

Azula raised her arm, and pointed to the tribe, yelling, "Attack!!"

The soldiers ran towards the tribe, and Hakoda yelled, "Attack!!" as the water tribe warriors attacked and everything started when fire hit water and spears and swords met.

Aang had been fighting for hours. His leg ached, but managed to take out most of the Fire Nation Army by himself. He also had been slashed across his abdomen, but it wasn't deep. But more and more soldiers kept attacking. And now, it wasn't like when he was 12, taking out the Fire Nation with a few air blasts, knocking them out just so he and his friends could get away. Now, older, and fully realized, the Avatar was out to kill. He was sick of these heartless humans killing the innocent. And he wasn't so innocent anymore, either. As he took out soldiers left and right, he protected his own soldiers around him.

He took out another 5 soldiers when he saw Tahn ahead of him. He perked up and took out the remaining soldiers around him—for now. He stood back to back with Tahn. "I guess we met on the battlefield again after all, huh?"

"Aang? Thanks!"

"I got your back!" he said as he took out 3 more with a waterwhip.

"Thanks! Again!"

The two kept attacking and fought off as many as they could. They split up after a while. And as the sun started to set in the western horizon, Aang took out another hundred troops while in the Avatar state.

Just as he came out of the state and fought some more, he saw Tahn fighting 15 troops alone. He was taking a few out when one behind him drew his sword. Aang stared.

"Tahn, behind you!" he yelled.

Tahn turned but was not quick enough. The soldier stabbed him through the gut, and the sword's point exited out Tahn's back. Everything turned slow motion for Aang as he watched his friend drop painfully to the ground. His eyes widened as he saw the soldier was going to finish him.

"NOOOO!" He yelled, throwing a huge gust of wind towards the soldier, blowing him away. Aang ran up to Tahn as more soldiers came. He earthbended a huge blockade around him and the body. He grabbed his friend, whose life was quickly leaving him. "Tahn! Tahn!" Aang yelled, patting his cheek. Tahn's blood was draining from his face. His blood flowed all over Aang's clothing. "Come on, buddy, don't do this to me! You saved my life, I have to save yours. Come on!" he said as he picked up the limp, pale, and bloody body in his arms. He bent a hole in the top of the makeshift barricade and bent water from the air to make a wave to ride out on. He had to get his friend to medical care.

As he bent the wave, then a makeshift elevator up the wall, he felt no warmth in his friend's body. Aang tried to warm Tahn's body with firebending. "Come on, Tahn, stay with me, buddy! You'll be okay!" he said as he ran into the medical ward.

"Please! I need a healer! This man has been stabbed through! Please!"

A young nurse ran to him and grabbed his arm. "I'm a healer; follow me," she said as she lead Aang to an empty room. "Take his armor and shirt off, and then please leave the room."

"Okay," Aang said as he took off his friend's armor, and then his shirt. He gulped when he saw the massive wound, but breathed a little easier when he saw that his friend was still barely alive, from the blood pulsing out of the wound.

"I'm leaving," Aang said as the nurse waterbended and made it glow. "Please, save him." He ran up the stairs and into the waiting room.

Katara fought off as many as she could. This battle had been going on for ten hours now, and many had died, on both sides.

To top it off, the storm was horrible, with gusts all around her, and hard snow and hail pelting her and everyone around her. She fought off another set of attacks, but she was getting tired and getting cramps. But she didn't back down. The storm made everything dark and fuzzy, and she could hardly see. But she saw a quick burst of blue flame ahead, and she ran toward Azula.

Ty Lee and Mai were about to switch sides when Zuko came into view of the three girls. When Mai saw him, she smiled, seeing that he was okay. Now that he was older, he looked so much more handsome. But Azula didn't notice. She was too busy trying to kill her brother once and for all. She shot lightning after lightning after him, but he dodged them. She finally managed to hit him in the shoulder, and he cried out, falling to his knees in the snow.

Mai couldn't take it anymore. She took one of her daggers and threw it at Azula. Azula turned at the last second and evaded it. But she was suddenly punched in the face by Ty Lee. She fell into the snow.

Ty Lee helped Mai up and they both ran towards Zuko. He looked up and saw what was coming for them.

"Mai! Ty Lee!" he cried as loud as he could. "Look out behind you!" They both turned and saw lightning coming to strike them. Ty Lee dodged it easily, but Mai couldn't. She was hit and shot backwards in the snow.

"Nooo!!" Zuko shouted as the smoking body hit the snow, lying face-down. Tears fell and froze to his face as he crawled towards her and gathered her in his arms, rocking her body back and forth in the snow. Ty Lee crawled next to him, crying.

Azula walked towards them. "You know, Ty Lee, I've known that you and Mai were going to betray me for months. You two are so gullible. And Zuzu, I'm glad I can kill you now so you won't ever stop me. Father will be overjoyed. You really are a coward, running out to this wasteland to hide. I'm going to enjoy wiping you three off of the face of the planet!"

She laughed wickedly and pointed her fingertips towards them in the snow. Zuko closed his eyes and put his arm around Ty Lee in protection. He waited. He suddenly heard Azula gasp in surprise as she started to fight off someone else. He looked up and saw that Katara came to their rescue. She froze Azula's hands and feet together as Zuko picked up Mai and ran with Ty Lee into the storm.

Azula melted the shackles that bound her. She turned to Katara. "Well, I see that you and the Avatar got a little busy since the last time we met," she said, eyeing Katara's stomach.

"Yes," Katara hissed. "And you and your damn father are the reason he's not here!"

She sent an ice column hurtling toward Azula, but she jumped it and shot blue flames towards the waterbender. She ducked and turned, narrowly missing. She took snow from the sky and crashed it into Azula, knocking her down, but she quickly got up. She sent lightning towards Katara, which she blocked with ice. Sokka came over the hill and watched as his sister knocked Azula over, but Katara looked weak.

Katara's cramps suddenly got very intense, and she felt warm liquid running down her legs. She grabbed her stomach. "No," she whispered. "Not now!" She had to defeat Azula fast. But as she looked up, Azula headed straight for her, shooting her with lightning. Sokka saw his sister get hit, and he watched as she flew back and hit a hard piece of ice, and fell face down into the snow.

"NOOOO!!" he screamed, but the storm drowned out his cries. Tears came as he ran behind Azula, hitting her in the back of her head with his boomerang. Azula fell over, blood covering the snow around her as he ran towards the fallen body near the ice.

He flipped his sister over and checked for a pulse. It was raspy and out of pattern. He took off his own jacket and put it over her. "Katara, please, stay with me," he said, his tears freezing to his cheeks. "Your baby needs you. Aang needs you. I need you!" He covered her with his body, trying not to squish her, but trying to keep her warm. He looked around into the storm, wondering if help would come. Just then, he heard someone calling his name.

"Sokka! Where are you?" Ty Lee yelled as the storm got even worse.

"Over here!" he yelled. She saw him and ran to him. "What the heck are you doing here?" he yelled, recognizing her, his voice turning angry.

"I switched sides. Zuko wants to know where we go to so that it's safe."

Sokka immediately thought of the crystal caves. Now was no time to ask for Ty Lee's trust or allegiance. He looked at his sister, then back to Ty Lee. "Tell Zuko to head for the hot springs. Hurry!" She took off.

He got up and picked up Katara as Toph ran over the hill. "Toph! Down here!" he yelled. She slid down. "Where's Katara?" she asked.

"In my arms. She's badly wounded. I need you to go back and get as many blankets as you can and bring them to the hot springs. Hurry!"

He started to walk, and he felt something dripping off of his arm. He thought it was blood, but it wasn't. He looked at her pale face and his eyes widened. "Her water broke," he whispered. He started to run.

They all eventually met at the hot springs. "Toph!" Sokka said. "Underneath you is an entire crystal chamber. I need you to bend us into it and seal the top. Hurry!"

She opened a hole in the ground and they were soon all in the cave. Zuko saw some wood Katara had put there in the corner years ago. He brought them to the middle of the room and lit them. But their work was far from over.

Okay, so some battling, Tahn is fatally wounded (will he live?), Katara and Mai are unconscious, the five warriors are stuck in a cave in a terrible storm, and is the baby coming? Please read and review, and tomorrow I'll update 2-3 chapters! Thanks for all of your guys' support. I hope you enjoyed the story! Read and review!
