I have had this one ready for a while, I just haven't gotten around to posting it. This is the Prequel to the Unclean. It seems everyone was curious as to how Aang joined the dark side. I hope you enjoy it. Please let me know what you think.

Yuck Factor: Other than some kataang 0

Fluff Factor: Nothing fluffy about what happens

Creepu Factor: 4

A shudder underneath his moving body let him know that the beautiful caramel skinned woman had her fill. Slowly his body tensed as he reached that hot intense few seconds before release. He held his body above hers as he felt something in his chest move in a way it had never done before. Quickly he brought his hand up covering his mouth as a fit of coughs took over him. Before he could move from on top of her blood began to spill from his hand. Katara let out a scream as the blood dripped thickly down onto her chest. Aang quickly jumped away from her and stumbled almost breaking his arm on the door as he tried to make it to the rest room. The slam of the door shook the small wood house. Katara swung her legs over the bed not bothering to wipe the blood from her as she pulled on his robe that had been discarded in the heat of their passions. She tried to push the door open but it wouldn't budge. She listened through the door as his coughing began to sound more like a bark.

"Aang, are you okay?!" She screamed through the door, but the avatar ignored her. He stared down into the small water bucket as he coughed watching the blood stream from his mouth. A shiver ran over him as he began coughing again. As if someone had kicked the back of his legs, he fell to his knees as his eyes began to water. He lurched as the intense coughing began to gag him. He opened his eyes as he felt thick mucus on the back of his throat. As he proceeded to spit out that sickening slime, his eyes grew wide. Black ooze slipped from his mouth as his blood had done only moments earlier. He flung himself back from the wash bucket and covered his mouth. He tried to control the coughing as his mind reeled about what was happening to him. As his coughing began to subside he let his eyes drop to look at his stomach. He felt bile tickle the back of his tongue as he looked over the black spider web that was stretching under his skin along his veins. The threads moved down, and a streak of black curved sickeningly into his now flaccid member. He closed his eyes and let his head fall back against the wood wall. Tears streamed down his face as he coughed in random intervals. He knew what he had done when he made that promise, but that was years ago. He had bled for one purpose and that was granted, but he had hoped the debt would come for him in his older dying years. A gentle knock came to the door as Katara's voice sounded through the wood.

"Are you okay? Let me in."

"I'm fine..or I'll be fine. It's almost dawn anyway…you need to be getting home to your husband."His voice trailed off. Katara scoffed through the door.

"Aang, you open this door and let me see you."

"Katara. Go home."

The water bender's eyes filled with tears as the anger filled her. She pulled his robe from her and used it to wipe the blood and other fluids that were running down her body. She tossed it to the floor and gave the bathroom door a horrible look as she pulled her clothes on. With a thundering slam she was gone. Katara wasn't the kind of person to be tossed aside like a used napkin. She wasn't just a mere release of pleasure and she damn sure wasn't his whore.

Haru wiped the sweat from his brow and looked up at the sun still clinging to the sky in a futile attempt to light the night. He let his legs go out from under himself as he fell down into the soft freshly plowed ground. Katara, his beloved wife, was on yet another trip to the Southern Water tribe to make sure that all was well. Haru closed his eyes and let himself relax into the loose sod. Sokka could handle the tribe, but Sokka was also at the moment separated from his on again off again girlfriend. So little sister had to heroically go to save her brother and leave her husband to tend to their clan. Haru opened his eyes and rolled to sit up. One thing bothered him though. Sokka was at the Fire Nation visiting with Fire Lord Iroh.

He shook his head and pushed himself up from the dirt. He pushed his hair back out of his face as he walked to the small house that his friends hand helped him build. He stopped and said a small prayer to the spirits at the small grave just outside of the garden. Teo had made it through the war only to be taken by an infection months after. He let his fingers rest on the grave marker for a moment before he walked the rest of the way into the house. He walked through the bedroom and into the wash room. Splashing water over his face, he cleaned himself. There were tainted thoughts in his mind and a sore spot on his heart. He washed the rest of himself before pulling on a clean tunic. He sat down on the bed taking in his hand the crumpled discarded letter he had thrown on the nightstand.

His hand shook as he opened the paper and read over those words once again. Words from a man who he had once called a friend. Words that described in horribly painful details just what transpired on those random trips to the Southern Water Tribe. Hauntingly descriptive words that left images dancing in his mind long after night fall. With rage filling his mind he crushed the letter in his hand, make sure that the Avatar's seal was completely crumpled.

Haru drew in a painful breath as he tried not to envision the things tormenting his mind. He stood up and tossed the letter into the hearth of the fire place, where all of the letters ended up. He walked briskly to the door and let out a shrill whistle for his ostrich horse. Just as she always did, Hunani came running with a squawking whinny that made him smile. He fed her a carrot from the barrel near the door as he smoothed her ugly feathers. He mounted the beast and clicked his tongue against the roof of his mouth, coaxing the creature into a steady trot toward the village.

The village was small and humble compared to some of the other Earth Kingdom villages, but it was just enough for him. To call it small in any other stance would be unfair. There were close to three thousand occupants, a school, a prison and a temple. And the latter is just where he happened to be headed. He pulled Hunani to a stop just before passing through the gates.

A soft smile spread over his face as he was met by a small girl only about six years of age. She met him every time he came to the village. She was bright eyed and the typical Earth Kingdom child. A sadness washed over him as she took his ostrich-horse to her parents inn for safe keeping. He wanted more than anything a child to love and care for. Perhaps it would fill that hole inside him that Katara had created. He walked through the the small streets smiling at the vendors and the people milling about. He moved about the path ambling, taking up time. He had no need to rush. There was no one waiting anxiously for him to return home. He stopped at one of the many merchants and picked up a small gilded mirror. Three gold pieces wasn't bad for such a marvelous craft. But what use did he have for it? He wouldn't dare buy it for his wife with the thoughts that were currently swirling in his head. He set it back down and moved his hand over to pick up a small jade figurine that was only one silver. He moved his fingers over the small valuable, careful to admire the craftsmanship. He looked up at the sleepy eyed merchant and grinned. He dug into his pocket and set three gold pieces on the table before walking off. He looked up at the temple at the end of the path. He sighed and gripped the small idol in his hand. He heard the small woman exclaim out loud from the over payment. He smiled as he listened to her weep in joy at his kindness. The people of his clan were not rich like those of Ba Sing Sei, so he had no qualms about sharing his wealth. He had a nice trade between the fire nation and his village. They could get most of their trade from his village that was right off the coast rather than take days to travel inland and pay more.

He moved off of the dirt road onto the finely shaped rocks that made the path to the temple. He walked up and looked at the long silk rope that hung near one of the support pillars. His eyes traced the deep red fabric up the pillar to the golden bell at the top. He shook his head casting off the temptation to pull the rope. He didn't need to alert the entire village of his arrival at the temple. He was only a few steps in before he was greeted. The village priest seemed to always know when he arrived.

"You must be bothered again to come so quickly back." The priest laughed. Haru nodded and looked around the temple. The priest stepped to the side and held his hand out. "You know the way well, my lord." Haru narrowed his eyes at the man. He didn't like to be called lord. He was the head of his clan, most of which he had welcomed to his village after his father died and their's was destroyed. He didn't like to be called chief, mayor or anything that might signify that he was on a higher level than the others.

"I need council." The priest nodded as Haru spoke. He followed the shorter man into the nirvana room and made his way over to the large fire place.

"I would assume so." The priest said with a hidden grin. He quickly put the pot of tea over the fire and turned back to Haru, who had settled down on the bunch of pillows. The priest moved quickly over to sit opposite him.

Haru let out a strained sigh and shook his head. The priest didn't let him start his sentence before he began asking questions.

"I fear that my vision has come to pass. Is that why you are here?"

Haru looked up at the priests, whose face was written in concern. He lowered his eyes to look at the floor. The priest had told him months before that a vision had came to him while he was meditating. Within the holy fire danced two people, locked in grips of passion burned their souls as they sunk into the darkness until the fire was nothing but smoldering embers in the hearth. Haru's green eyes looked up at the priest with sadness enveloping him.

"Perhaps I should abandon the notion of having a family. I couldn't bear the contention between me and my wife if a child were to become involved." He said and shook his head as the incense curled around him. The priest watched the young chief with intense and focused eyes. The darkness hanging over the man was enough to call evil spirits to the entire town.

"Abandon the notion of having a family? Perhaps that is what you need more than you think."

Haru looked up at the priest and frowned. His eyebrows knit together as he watched the tall man stand and move over to the boiling kettle.

"To not have a family?" Haru's voice betrayed his sense of control. The priest turned smoothly as he poured Haru a cup of herbal healing. The taller man shook his head as he sat down opposite the young chief once again.

"No, I meant that perhaps you should have a family."

"Why bring a child into fighting and dishonest?"

"Sometimes, my friend, the only way to tether a wild boar, is to take their young." The priest's voice was low, but his gaze didn't waiver. Haru frowned and looked up at the priest with confused eyes. But as his eyes settled into that powerful glare, he felt as if he were paralyzed. He pulled himself out of that gaze and forced himself to look back at the leaves swirling in the bottom of his glass. Haru shook his head and set the cup down.

"I must leave. But I must say that I am not sure that I could stomach what you suggest."

"It is your decision to make my friend." The priest said with a smile and a nod. Haru nodded and bowed in thanks as he tossed the small jade figure in the offering dish.

Katara felt sick with herself. She was not a person to be used and disposed of like a common nose rag. She was not a tool nor was she a toy. A gag tore from the back of her mouth as the thought of him using her caused her stomach to lurch. Her blue eyes glared down into the water, staring with contempt at her own rippled reflection. Her face contorted as once again her stomach rolled. As she threw her head over the side of the ship, an even further sickening realization slammed full force into her mind. For a few weeks she would have a sickness come upon her suddenly. She spat the last bits of vomit from her mouth that had elected to linger. The blood fled from her face as her hand, shaking with fear, rose to cover her mouth, stifling the gasp that forced itself from her chest.

She had thought missing her monthly burden was just a product of the stress and traveling. She had skipped several of them while traveling with Aang before the final battle. So she had thought nothing of it when she missed one. Tears escaped her eyes as she fell to her knees.

She was going home to her husband pregnant with another man's child.

Yeah no major twist yet. But I do have one planned. :) Thanks for reading.
