A/N: I don't exactly know where this story is going, but it doesn't follow the series Rebels or have anything to do with the TV show at all.

Disclaimer: I don't own Star Wars, but if I did Obikin would be canon. I'm only going to write out the Disclaimer once because I honestly can't be bothered to write it out for each chapter. I'm lazy XD

The Heat

"You're not serious!" Shouted the woman in red, her pale arms brushing against the silken dress that she wore ever so elegantly. He stared back at her in defiance, yellow eyes burning like the sun. The woman knew very well that he wouldn't give up on the matter, "If you do this, everything changes!"

The Sith Lord knew this as much as she did, that if he dared to save his former apprentices life it was a betrayal to the Sith Order. He knew very well that Cassius would want to turn her into the Empire. So of course, with his sanity of which he valued, he took the matter of Ahsoka Tano to one of his oldest friends, Shala Verowen. She was a stubborn old woman, and surprisingly, she still looked good at five-hundred and three. He had met the enigma that was Shala three weeks after his rather eventful fall into the extensive abyss of which many called the Dark Side of the Force. And over the time that he knew her, the long tiring seven years of the loyal companionship of which they both held tightly to their chest. He the suspicious, jaundiced Sith Lord, that hardly ever trusted a single soul, would put his life in her hands.

"If the Emperor finds out about this." Darth Vader frowned, his lips twisting into a bitter scowl, at the mere idea of Shala actually telling the insidious man of what he had done. "Oh relax will you, I won't tell him. You want her healed then?"

Running a hand through his blonde locks, tugging silently on them in frustration.

"You healed me, why can't you heal her?" Asked he.

Shala raised a brow, with a fond look upon her face. "Yes, because you're my best friend. I don't usually go around healing enemies of the Empire!" She huffed.

Vader's lips twitched. He could barely restrain himself from chucking, an act of which he hardly ever did.

Shala's fingers twitched around the necklace that hung tightly around her neck, clenching at it in stress. An act that Vader was quite familiar with, one he never commented on. He knew it was best not to, an angry Shala was a rather dangerous one.

She had crystal white hair that seemed to glitter in the sun, of which Vader on his happy days liked to admire, her fashion style often reminded him of his long passed wife, a woman that he missed with all his heart. Padme would have loved the craziness that followed Shala, he himself often wondered how he had formed such a positive relationship with Ms Verowen. There wasn't much to say on the matter of her eyes, for they were much like his. "Let's say I heal her." Commented Shala, hesitating for a moment. Her eyes glancing at the unconscious figure of which was Ahsoka Tano, whom he had pulled out of danger, his attachments getting the better of him. He knew that Sidious wasn't fussy on attachments, but when the said attachment was a former Jedi, things could quite obviously get messy fast. A situation Vader wanted to avoid at all costs, this much was obvious to Shala. "You owe me!" She hissed at the towering blonde that stood before her.

Vader nodded his head in a silent agreement, as Shala stepped forward, hands shaking. He watched in fascination as she went on healing Ahsoka, her pale palms glowing a bright golden, that appeared to jump out of her skin and bind itself around the injured body. Placing Ahsoka in a golden glowing cocoon, he gazed at the energy with eyes wide.

"Is it working?"

Shala didn't utter a word, remaining silent as she continued to heal Ahsoka. He felt the need to huff, but he knew it would sound rather undignified and childish of him, and no proper sith lord would have the gal to act childish of all things.

"It's done," said Shala, her body moving across the room and collapsing softly into the closest chair that was near her shaking body. "You alright?"

Shala nodded, reaching up with one hand to rub her forehead, hoping to cure an ailing headache.

Ahsoka didn't instantly wake up, much to the relief of Vader. He would have preferred to leave her somewhere, without her knowing that it was him that had dragged her from the bomb site. However, Shala wanted to keep a watchful eye on the rebel knowing very well that her healing period wasn't quite over yet.

Vader was most surprised when Shala informed him of having to watch over her because of Ahsoka's second gender being that of an omega, and because of her gender, it takes longer to heal when helped by a Beta. This information wasn't something Vader was aware of, he knew of the second genders and how they presented in the normal population of the Galaxy. However, he had never met a Force-Sensitive Omega, he wasn't even aware they existed. In fact, he only knew of Force-Sensitive Beta's. At the time, he was unsure if he wanted to learn the differences, for surely he had better things to do than read up on the second genders. But he didn't exactly have much of a choice, considering that Shala forced him to sit back down, and 're-educate himself' as she so called it.

Despite scowling at the idea, and making a fuss about it, which Vader would deeply deny doing much to Shala's amusement, the read was rather intriguing. The presentation was what caught his interest the most, was the studies done on presentation in force users, which was completely different from the average person. Vader had read this with eyes wide open, looking at the Data-Pad in fascination.

The Presentation of the second gender is commonly known amongst many in the Galaxy today, but what is uncommonly known is the presentation of those who are force sensitive. For most species, at birth, they are born either female or male.

The non-force users commonly present around the age 13-18, there are also late bloomers of the second gender. However, if one doesn't present by the time they are 30 years of age they are classified as 'female' or 'male' and they, unlike others, don't have a second gender (Alpha, Beta or Omega). The presentation is followed by a Heat or Rut, those who have neither are then classified as Beta. The difference between a Beta and an average Male or Female is the fact they have clearer eyesight and a stronger sense of smell. After this, they will give off a particular scent which shows if they are an Alpha, Beta or Omega.

However, in force-sensitives, this is a completely different matter. Casidus Presentation is what the healers usually refer it as. Some force users stay 'male' or 'female' for the rest of their lives, but others can present at any age beyond 13. The only time of which a force-user presents is when they make a highly important life decision which will alter their future, this all revolves around the force, according to many Jedi and Sith Healers. And sometimes has to do with the Force Ancestors of the Orders. Some regard it as a judging ceremony of your life, but this can become problematic in both Orders.

The Jedi Order- They are well known for their use of what many call the 'light side'. However, on presentation, this can cause problems, Alpha's when they are force-sensitive strongly feed of the 'Dark Side'. There have been Jedi that can fight this and carry on, but sometimes this can lead to a path of self-destruction. The Alpha's are usually tightly controlled in the Jedi Order.

The Sith Order- Being a Force-Sensitive Alpha is an honour in the Sith Order, and some call it a gift from the force. However, when a Sith Lord presents as an Omega their name is cast off and they are looked down upon as being 'weak'. Mainly, because Omega's naturally channel the 'light side'.

Vader turned off the Data Pad and continued to look at the blank screen in wonder. He was fascinated with the nature of an Omega and Alpha that presented in force sensitives, changing the lives of those that had been gifted by the force. Although the Sith Order clearly thought being an Omega was a disgrace, Vader didn't quite agree with this. The force, itself wouldn't create weaklings in an Order that was harsh and brutal. Despite disagreeing with this particular matter, he certainly wouldn't like to present as an Omega, for that would ruin everything he had ever gained through the Sith.

He walked over to Ahsoka, examining her from head to toe and noting how much she had changed over the years. He frowned, pondering on the fact that she was rather tall for an Omega, was that a force sensitive development? Were only Force-Sensitive Omega's tall in height? She had aged well and with beauty. Even when she was still and silent, not moving a muscle, she appeared elegant on the healing bench.

She is rather alluring, he considered.

He wished to touch her skin. Longing to know if she was alright, Vader felt drawn to her, something lost and forgotten calling out to him. A siren call, perhaps. He knew that saving her went against everything he was taught, but his love for her hadn't dimmed over the years. He glanced back at Shala, frowning in concern as he noticed her sleeping form. Observing, that even in her sleep she radiated feelings of overwhelmed exhaustion.

Vader knew that her healing abilities often gathered a lot of energy, but she didn't usually collapse in sleep that quickly.

He wandered over to slip a cotton blanket over her sleeping form, as she snuggled into the comfort that it gave.

"I," Ahsoka paused, "I didn't think you would save me."

Vader jumped in fright. Not that he would ever admit that he did such thing, however, he turned to her in surprise. With as much strength that she could muster, she pulled herself up into a sitting position. He wished to speak words like, 'Don't, you'll only hurt yourself' but he knew that she would take that as a confirmation that he still cared. Which he did, but Ahsoka didn't need to know that. Her long legs dangled over the side of the bench, she looked to the ground, considering if she should jump. As her muscles flexed, she winced in pain, then knowing that it wouldn't be such a great idea.

Her bright ocean blue eyes looking into yellow, or a colour that strongly resembles amber. And even though so much had passed, so much time, along with many tragedies including that of Anakin Skywalker. Ahsoka knew she could trust him, which probably was a terrible idea within itself, considering he was an infamous Sith Lord.

The longer he stared into her radiant mirthful eyes, he seemed to feel more like the man he used to be. That with all things considered, including the Order, and Darth Sidious, wasn't a good thing. However, he didn't wish to do her any harm. Such an action as that was inconceivable, something he couldn't possibly consider.

"Are you planning on turning me in?" Asked she, "Just let me know, so I can run."

He snorted in amusement. She always seemed to get a rise out of him, and usually a positive one too. It appeared to the Sith Lord that her fashion sense had gotten even more unique, he honestly wondered how she walked through cities without being noticed. It looked quite similar to the slave garments he used to wear on Tatooine, but in shades of blue and grey and looked to be rather shiny with sparkles of light when a speeder flew past.

"No, I-I don't." Stuttered Vader, then wishing to smack himself in the face, rather violently too. For it had been a very long time since he had stuttered and almost flushed, and thank the force he didn't do that. But he could have, and that seemed to make it even worse. Ahsoka gave off the impression of being amused at his little act of embarrassment, as his fingers clenched into the dark material of his robes. It all felt like a dream, and a rather wild one, he would hardly ever dream of her. And if he did, it usually ended in tears, not for him of course, he never cried.

Ahsoka carefully slid down off the bench, her muscles clenching in pain at the slight movement, her hands holding her body up. She knew not to take them off the side of the bench, she didn't wish to collapse on the floor in a heap. Vader wondered if she was alright, but didn't bother to ask. For she seemed to be standing up just fine, and the only sign of pain was her slight frown placed upon her lips. But he knew that Ahsoka was the type to bounce right back from hideous injuries, knowing this from experience.

Well, he certainly hoped this was no different.

Ahsoka tried to straighten up, rolling her shoulders, and attempting to get past the pain that flew through her nerves. She did all this with her eyes still gazing into Vader's, reassuring herself that he wasn't going anywhere and that he had helped her. So surely, he wouldn't hand her over to the Empire.

He won't, I know it, she thought, eyes narrowed on the twitching form of Darth Vader that stood before her.

She admired the difference in his features, he looks even more handsome than before. Not that Ahsoka ever liked him in that way, the mere thought of that made her shudder in disgust. But he certainly did look much more handsome, and even elegant in some ways.

His blonde hair was curly, in long thick locks that hung a little past his shoulders. His eyes instead of blue looked remarkably like the twin suns of Tatooine. They were sort of pretty, she considered, not that he would appreciate that thought.

"Hmm," muttered Ahsoka, "the eyes suit you, but they looked nice when they were blue."

Vader heard this and didn't quite know what to say. This whole situation was rather perplexing, he couldn't do little but stare at her in bewilderment. Feeling quite unsure of himself, rather unsure of what to do in a situation like this. All his courage and lack of fear, when faced with the past of Anakin Skywalker, seemed to have faded. He usually destroyed his links to the past of Skywalker, but he couldn't do that to her. So what could he do?

Finally, she managed to regain the strength to remove her hands from the bench, her legs tensing along with her spine as she stood up straight. Wiping the sweat that had gathered on her palms onto the soft material of which she wore. She took one step forward, one leg shaking more than the other. She slowly paced from one side of the room to the other, trying to stop her legs from wobbling. Vader had trouble concealing his amusement as he watched his former apprentice treading across the room. He was quite surprised at her strength, as she quickened her speed.

"Oh don't be so surprised," Ahsoka exclaimed, "we both know that I recover quickly. Faster than you, that's for sure."

He scoffed at the idea, for he had lots of strength, and he carried it with pride. Using it in battle to defeat others, with a victorious grin on his lips. He was slightly miffed that she was poking at his strength, even if it was slightly true. He did, in some situations, take longer to heal. But that's only because trouble seems to follow me everywhere, even as a sith lord! He reassured himself, and it was very true. Chaos appeared to be very much in love with him, and quite obviously couldn't get enough of him.

She raised a brow as if she could read his thoughts. And much to his horror, he actually blushed. His lips twitched, longing to scowl in exasperation at the high-spirited woman before him. He couldn't outright believe that he had actually blushed, how embarrassing!

It was almost like his sith personality was flowing, with high speed, down the drain. He could still feel the tip of his ears burning, and he just wanted it to all go away, but unfortunately, that certain wish wasn't being granted.

"I didn't know Sith Lords blushed. Or are you just mentally impaired!" Giggled Ahsoka, and this time he did indeed scowl. Although it wasn't that frightening to her, for she didn't stop laughing.

"What!" Hissed Vader, glaring at her. "Of course not! Why would you even think that in the first place?" He uttered, gazing at her in irritation. For if there was one person that could really get under his skin, and irritate him to no end, it was certainly Ahsoka Tano.

Well, Obi-Wan could do a pretty good job too, but Vader stopped that train of thought, not wanting to shake in anger. Or, more correctly, shake the apartment in a rage. For the mere mention of his name, made him want to spit out 'traitor' in a fit of fury.

"No, really? Why didn't you leave me to die?" Asked Ahsoka, the atmosphere suddenly turning grim, along with her usual pleasant smile. I couldn't, thought Vader. He was very glad that Ahsoka wouldn't be placed in a sith trial, where he would have to kill her, if such a thing happened, he would spectacularly fail.

"I," Vader hesitated to reply, gazing into those eyes he had so dearly missed. The blue gaze of a sister whom he had loved intensely.

"I know I should have, but I couldn't. Would you?"

Ahsoka sighed, her fists clenching at her clothing, palms sweating again.

"No," she spoke, "but I'm not the Sith Lord."

"It seems that even in another Order, I still have problems with attachment. Which is shit, really."

"Well, don't tell the Emperor that."

"Definitely not, unless I want my head to roll!" He exclaimed. Ahsoka tried to conceal her snort of laughter behind one of her hands but epically failed. She wondered if he had completely fallen to the dark side, for he didn't feel evil.

"Can I trust you?" She asked, feeling slightly stupid as she did so. Ahsoka knew that you could never trust a Sith Lord, but she felt deep down inside that he could be trusted.

"Yes," Said Vader without hesitation, he wouldn't betray her to the Empire. The idea made him cringe, and feel rather indisposed. The sensation of illness sweeping through his stomach, as he felt the need to vomit. I would never, he insisted.

Ahsoka stepped forward, as they stood face to face. And this time, he didn't look down. They were almost the same height, she was only a little bit shorter than him.

She paused, seemingly rethinking through what she was about to do. He observed her, as she appeared to be in a state of deep thought.

Before he could think of what she was about to do, she quickly embraced him, wrapping her arms around his shoulders, and squeezing tight.

He froze, his body suddenly becoming stiff, almost to a point where it hurt. Vader wasn't used to being hugged or garnering affection in general. It just wasn't done.

"Do you usually hug sith lords?"

She laughed and smiled at this particular comment. Ahsoka hardly had the time to hug anyone these days, with time being short, and forever being on the run from the Empire. Or, it was simply because most of her friends were dead. It was a depressing matter, a topic of which Ahsoka didn't want to think on for much longer. She had cried and screamed many of times over the years, as the losses kept piling and forever continuing. It almost seemed endless, she wanted them back in her grasp, to hug them tightly to her chest. So she could whisper, I'm never letting you go.

"Anakin."

"People don't call me that." He pulled her to him, their bodies almost becoming one. At that moment, he felt clearer than he had in years, the pressure being lifted, a weight he hadn't even noticed before. It felt like light, he tried to push it out, but it appeared to be very consistent, almost like a leech. The light suddenly felt very real, wrapping tightly around him, burning his stomach in fierce agony. "Ugh," he grunted out in pain as he stumbled back from her arms, clutching at his stomach.

"Are you alright?" Ahsoka asked, stepping forward in concern. She wanted to reach out for him, but she knew he wouldn't appreciate it. So her arms stood by her side, twitching slightly. Vader couldn't speak, his tongue suddenly feeling tied and his throat swollen. Rather like he had promptly come down with some illness, which was odd for him, for through all his sith years he had never gotten sick. Sidious had informed him that it was the dark side that kept it at bay, and preventing any serious or feeble diseases from taking hold of his body.

Ahsoka took in a deep breath, immediately looking at him in horror. He knew with just one look that something was very wrong, as the dread settled in his chest.

"You can't be!" Ahsoka exclaimed, with terror in her eyes.

Vader stared at her. He couldn't quite understand what was going on, but all he knew was the pain. And he had felt pain before, having felt lava crawl up his body and burn viciously through his muscles. But this was something different, an internal pain, and it was consuming him. What the hell, he thought as his knees buckled and he fell to the floor. This time she didn't hold back, rushing towards the shuddering form on the cold ground, praying to the force that he was alright. Vader may not have known what was happening but Ahsoka did, and she didn't wish it upon him. The pain that came with it, the struggles and the difficulty to live in the Galaxy in peace.

Vader couldn't respond to Ahsoka's worries as he continued to convulse on the floor. She looked around the room in desperation for something to sedate him, her gaze only falling on the sleeping body of Shala. Swiftly walking over to her, clenching her fingers into the woman's shoulder as Ahsoka shook her.

"Wake up, wake up, come on, please!" Shouted she, frustration gripping at her throat.

Ahsoka if she knew the mysterious woman would have known not to wake her, she could be quite brutal when she wished to be, but the situation was dire. So even if she knew Shala, it wouldn't have mattered. Yellow eyes snapping open to stare into blue, in alarm she threw Ahsoka down onto the floor. Her legs tensing, getting ready to pounce on the former Jedi. Shala paused, gazing at her convulsing friend in fright. Rushing quickly towards him and dropping onto her knees, pulling away his sweaty palms that were pressed against his stomach. Shala immediately smelt the scent that seemed to be coming from Vader, she gasped.

"No, no, no," she murmured. "You can't be you hear me, you can't!"

Ahsoka frowned, knowing that nothing was going to be done to help Anakin if the woman consistently stayed in denial, ignoring what was truly going on.

"Are you stupid, he's in heat!" Shouted Ahsoka, the white-haired woman turned to her in a furious rage, her yellow eyes glinting.

"This is your fault, If he hadn't saved you, he wouldn't have been cursed!" Spat Shala, placing the blame on frightened Ahsoka's shoulders.

"It's not my fault he's an Omega," she paused looking to Shala with dread clear in her eyes, "This is first heat."

Shala suddenly became grim, with a frown on her lips. "Yes," she said.

Vader through all there shouting could hear them quite clearly, despite the pain that was wracking his body. The torment echoing through his bones and into his soul, and at the words 'Omega' he knew then that his torture had only just begun. When he had saved Ahsoka's life he was very much aware of the fact he would have been tortured if Sidious found out, but he never could have imagined this. To be an Omega, was to know pain and suffering, he had seen it all before. How the Galaxy looked down upon them, it was even worse in the Sith Order, he knew his fate wouldn't be pretty if the Emperor found out. He's going to kill me, nobody wants a useless omega, he realized. Not only would he have to face that the force had practically just stripped him of all his sith titles, he only just considered this as the light entered his body and filled his soul. For, after all, an Omega was a natural 'light side' channeler.

The first time he had seen it, he was but a little slave boy on Tatooine named Anakin Skywalker, with a harsh destiny. Of course, at the time he knew hardly anything of his fate, and he was innocent in mind and spirit. However, when he saw the man strike the non-slaved being with a whip he was severely confused. Much, later on, he would ask his mother about the being, and why a free person would have to be hit in such a way, and honestly, the reply he got didn't reassure him in slightest. For in the eyes of the Galaxy, other people have the right to harm an Omega. And from a young age, he had never understood why worlds of civilizations that had come so far, could be so primitive and stupid.

What gave others the right to raise a hand to an Omega, what was so different about them? Did they hold some secret power that others were afraid of? He never knew, and as he got older he slowly started to forget about Omega's. And when he fell, well what did it have to do with him? He shouldn't have had to worry about Omega's, he had more important things to do. Sinister things, for in that time of his life he certainly wasn't innocent any longer.

Heart throbbing in his chest, he refused to allow others to abuse him, to be acknowledged as a human that was below a slave. No, if he was going to be an Omega he would show others that he was better. I don't need an Alpha's approval, thought Anakin.

"You're going to be okay," whispered Shala, "You'll be fine. I know first heat's always hurt the worst. But you'll get through this."

Will I? Anakin wondered, and that's my name now, isn't it? He remembered being told by Sidious that the dark side gifts us our names, but they can be removed in certain events. Including presenting as an Omega, even Shala had said the same. I've lost everything, he realized.

"Is he really going to be okay?" Asked Ahsoka, remembering her first heat and how it felt, she highly doubted he was going to be fine.

"No. Everything is changing for him, especially inside of his body," muttered Shala.

"Are you going to tell the Emperor?" Ahsoka queried, looking at the Sith Healer in dread. He was aware of what they did to Omega's in the Empire. She would abduct him if she had to.

"Not if I have to."
