Chapter 4 A Lustful Betrayal

Strange events from around the world have been occurring. And these events arrived to the ears of Team Avatar. People in each nation fell gravely ill that no healer could cure. Strange floods came before the plagues. Then there are the many villages and towns that ate themselves to death, literally. A lot of people ate each other. Others, it seemed that they gave into their inner most desires. When these events happened, the earth dried up and cracked, and formed rock formations.

Other events nearly devastated Team Avatar. All of their efforts of uniting the nations together are being torn down. There were battles and small wars between the Water Tribes and the Earth Kingdom, the Water Tribes and the Fire Nation, the Fire Nation and the Earth Kingdom, and the Fire Nation fighting against the Water Tribe and the Earth Kingdom. People were dying, and before Aang could get there to stop the fighting, everyone, every man, woman, and child, was dead. Even in the battles that involved no Firebender, there were massive wildfires that scarred the land.

But then there were the strangest events that were happening in the world. There were rumors of the dead rising and attacking the living. However, there was no proof of this claim. Then there were people were dying of unknown causes, even the most healthy and strong people. The world was in utter chaos.

"Aang, please calm down." said Katara. She has been trying to calm Aang for weeks. He was at his wits end and was becoming the most hated person in the world, the Fire Nation Palace the only real safe place for him. "There's nothing you can do…"

"Kartara, I know!" screamed Aang. He was exhausted beyond belief. He wasn't sleeping as he was constantly traveling trying to solve these mysterious events. This is actually his first time seeing Katara in a week. "But it's my duty to figure out what's going on. I haven't even been able to contact Roku or any of the other Avatars."

"Has something gone wrong in the spirit world?" asked Katara.

"I'm not sure." said Aang. He sat on the bed and nearly collapsed. Katara caught him.

"Aang, you need to rest." said Katara. "You haven't spelt in a week. Your body will fail unless you rest."

"But Katara-" started Aang.

"No, just rest. Please?" Katara said.

"Alright." agreed Aang. He fell to the pillows and Katara placed the blankets over him. She then hummed a song to help him sleep. However, he didn't get more than five minutes before a servant burst into their room.

"Avatar Aang!" yelled the servant. He was wearing the traditional clothes of a servant of the Royal palace and had brown hair and green eyes. "I just got word! The is a large scale battle happening on the island just an hour east from here!"

"What?!" screamed Aang as he jumped out of the bed.

"Aang, please don't go!" yelled Katara.

"I have to Katara!" said Aang as he grabbed his glider. He kissed her goodbye and ran towards Appa. The servant ran part way with Aang, telling him the situation. Apparently the Firebenders and the non-Benders were attacking each other ruthlessly. Aang thanked the servant and hoped on Appa.

As Aang left, the servant waved goodbye. Then he started to cough violently. Black smoke started to come out with each cough. The black smoke then burst out of his mouth like a geyser and the servant fell to the ground unconscious. The smoke twirled around the servant and flew off into the palace. It flew around fast, looking for something. Or someone.

This black smoke flew past many servants until it found one girl. Katara. She was in her and Aang's room, sitting on the bed. As she sighed, the black smoke dived into her mouth and she was fully forced onto the bed. She tried to scream, but her mouth was full. She couldn't even thrash about. Soon, the smoke was completely inside of her. Katara sat up, with her eyes closed, and when she opened them, they were completely black.

"This'll do." said something within Katara's body, but not with her voice. Her eyes went from black to their real color. "Need to fix the voice though. Er-herm. *Cough* *Cough* Hello! My name is Katara…My name is Katara… My name is Katara… Katara… got it."

The entity within Katara searched her memories as it walked around the palace. It found that Mai, the Fire Lord's lover Mai was with her parents. That worked with what the entity wanted to do. Katara walked to the Royal Bath House, and found that there was steam coming out of it. Smiling, she entered. Inside was Zuko, with only his waist covered by a towel.

"My, my Zuko…" said Katara. "Looking good."

"Ah! Oh Katara, it's you." said the madly blushing Fire Lord. He grabbed other towels and covered himself. "What are you doing in here?"

"Looking for you." Katara said, eyeing Zuko intensely. She stepped closer, but Zuko ducked away and left the room. Zuko walked into a large sitting area that was just outside the bathhouse and sat down in a chair.

"Your acting weird Katara." said Zuko. "Hey, where's Aang?"

"Oh, he left and won't be back for a while." said Katara. She followed him into the chair and sat on the arm. "I'm all alone. And so…are…you."

As Katara spoke each word, she walked her fingers up Zuko's bare chest. Zuko quickly jumped out of the chair.

"Katara what are you doing?!" demanded Zuko.

"I'm bored and you're good looking." stated Katara. She backed Zuko to the wall. "What do you think I'm doing?"

"I think your wrecking everything you and Aang have together, and what Mai and I have." said Zuko, looking away.

"Ah, don't be a spoil sport." said Katara. She got closer to his face. "Let your inhibitions go and give in."

"I said NO!" screamed Zuko as he pushed her away. Katara fell on the other side of the chair. Zuko ran to her and kneeled down to help her. "Katara, I'm sorry! Are you alright?!"

"Oh, you're a bit rough." said Katara. She stood up and brushed herself off. "I like that."

Katara then grabbed Zuko by the neck and kissed him. Zuko tried to fight back, but Katara held firm. Then, black vein-like lines appeared around zuko's mouth and traveled to his eyes, then quickly faded. Zuko's eyes closed as he stood up, taking Katara in his arms. They continued to kiss passionately until Zuko pinned Katara to the wall. When they finally separated, Katara looked into Zuko's closed eyes. Zuko then opened his eyes, and instead of their usual gold were completely black. As he smiled, his eyes reverted to normal.

They started kissing again. Very rough. Zuko began groping her breasts after he ripped her shirt open. Katara dug her nails in Zuko's back as she moaned. She then slightly pushed Zuko away. When he gave her a look, she spoke up.

"Wait-" Katara said. "Let's go to my room."

Zuko didn't say anything. He just smiled and dragged her to her and Aang's room.

Two Hours Later

Aang couldn't believe it. He had flown Appa as fast as he could to get to the island, only to find out it was perfectly fine. Not a single supernatural event was occurring on the island. So he sped home as fast as Appa could take him. When Appa landed, Aang noticed that the servant who gave him the message was on the ground.

"Hey, are you okay?" asked Aang as he picked the servant up. The servant opened his eyes and looked dazed.

"Whe- where am I?" asked the delirious servant. "Why am I outside?"

"I was about to ask you the same thing." said Aang. "If I remember right, you were there when I left for the island that you told me about."

"What island?" the servant asked. "I don't remember telling you anything."

"Really?" wondered Aang. "What do you remember?"

"I was setting cleaning the dishes from dinner, when I felt very cold. Then I saw black smoke and I blacked out." explained the servant.

"Black smoke?" Aang thought curiously. "Let's get you inside."

Aang put the servant's arm over his shoulder and walked inside. Very quickly, another servant came and took him to another part of the palace. Aang then felt all of the stress and exhaustion he had hit him at full force. He walked to his room, wanting to hold Katara in his arms as he slept. When he got to the door, he heard Katara moan in pain. Worried, Aang burst through the door and felt his heart break.

"Aaahh!" scream Katara in ecstasy. "Yes! Zuko!"

"Katara!" yelled Zuko as he finished off. He fell on the other side of Katara.

"Katara, why?" asked Aang with tears falling down his face.

"Oh there you are Aang." said Katara as she sat up. She was naked, and was covered in bruises and scratches.

"How could you?" Aang asked. He was devastated.

"Because I wanted to, that's why." said Katara. "I wanted the bad boy Fire Lord, not a wimpy Airbender. Besides, I got tired of waiting."

"But I…" started Aang. "You said that you wanted us to, to wait before we did anything like that."

"Well I changed my mind." said Katara. "Get out Aang. We're through."

"Katara-" started Aang.

"GET OUT!" screamed both Katara and Zuko.

Aang then ran out of the room, out of the palace, in tears. He ran past Appa and ran to the edge of the island. Katara and Zuko both smiled at the shattered remains of the Avatar as he ran out. Katara cocked her head looked back at Zuko. When they blinked, their eyes went completely black. Then the black smoke forced its way out of their mouths. The smoke twirled around the two of them and after it left them completely, Katara and Zuko collapsed. The smoke then formed Chaos.

"He he he." chuckled Chaos. He nudged Katara with his foot. "Didn't I tell you that your love was a lie, Avatar? Ha ha ha ha ha ha!"
