Chapter 1

"It's so good to be home" Asmodiah thought as she felt the scorching hot temperature of Hell surround her body. She mused on the fact that for many demons, Hell was about as enjoyable as it was for humans, but things were different for those higher up on the food chains such as her.

She had just come back from an important mission, helping Lilith break a some of the last few seals. While the mission had been successful for the most part, she had spent too much time above and away from her duties. Plus, someone needed to report back to the king of hell and she was one of only six who were allowed in the room he had been trapped in so many millennia ago.

That, she thought to herself as she descended the seemingly endless staircase to Lucifer is exactly the story I will be reporting to him. The other details are... irrelevant in the grand scheme.

She knew Lilith wouldn't mention the real reason she was sent back. Lilith was too protective of her to do that. Still, if Lucifer found out that she had shown the slightest sign of weakness, there would be serious consequences. She had a whole level of hell to run. Lucifer would not think twice about taking it from her if he thought she felt mercy for humans.

And that can't happen. My brothers and sisters have always been waiting to steal my spot. Asmodiah was one of seven that were basically royal blood in Hell. Of her other four siblings she was definitely their parents' favorite. Always the most beautiful. Talented in the most twisted of ways. Lucifer had placed her in charge of the second level of Hell. An accomplishment she was proud of.

"How was your trip to earth, my dear?" Lucifer asked when she reached the bottom step, startling her out of her train of thought.

"Excellent, father. The seals are breaking fast and with little interference. It seems these so-called soldiers of the lord can't track our next moves. I'd say you'll soon be out of your cage and we'll be able to rule Earth together. These humans don't deserve it." She added the last sentence almost to herself, as if trying to remind herself to prevent any hesitation or mercy against them.

"Yes it seems so." he responded. Asmodiah arched an eyebrow; her father wasn't one for short responses. He tended to ramble for as long as one would let him. She didn't press, however. "So what will our next move be? We only have two seals left to break. Mother will have no trouble breaking another without me, but I imagine the last seal, just like the first is a bit more challenging." Her mind drifted to Lilith. She took after her mother more than her father and they were definitely closer. For Lilith being the embodiment of wrath, she was nothing but a caring mother for Asmodiah. She was Lilith's most treasured creation. The love she felt for her was almost human. The idea of that made her chuckle inwardly, thinking maybe that's why she couldn't spend too much time around humans without sympathizing a bit. It was then that she noticed her father was awfully quiet. He had turned around to face away from her as he paced slowly, as if carefully measuring what his next words would be.

Asmodiah began to get nervous. Her father did not lie. When he stayed quiet for so long it meant that he was searching for some way to answer without either lying or revealing too much. "Father, tell me what's wrong. You can trust me, I can handle this." Lucifer turned again to face her, " I know this is something that will be difficult for you. More for you than your brothers and sisters. But you're right, I have to trust you. You have a role to play in this. You will be my right hand as soon as I break free from this cage." Asmodiah gave him a puzzled look as opened her mouth as if to ask a question but Lucifer raised his palm to stop her. "Lilith... she has a role in this as well. She has always known it and accepts her fate. The final seal... it is her." Asmodiah paled, feeling a sense of dread creep up on her. She understood what he meant, but her mind seem to reject the idea as she shook her head "I don't understand. What do you mean it is her?" She shook her head again. She tried to convince herself she heard that wrong, that she interpreted it the wrong way, that obviously it was not the way it seemed.

Memories flashed behind her eyes. Her mother fixing her hair before important events, making sure she always looked stunning, mercilessly slaughtering whatever or whoever touched a hair on her daughters head, every talk they had about their destinies and the great things they would do. Lilith had never mentioned this. Would there even be a goodbye? Would there even be time to mourn before she would be expected to rule by Lucifer's side? Her mind wouldn't stop spinning.

"Child, this is fated to happen. It has been written for centuries. Now more than ever your mother will need your help. I know it's a lot to process, but you are strong enough for this. She must die at the hands of Sam Winchester. It will happen, and soon. I can feel it. It's about to happen." Asmodiah felt her heart speed up. She couldn't think straight anymore. She knew she had to save her mother, convince her not to go through with the plan, but there would also be hell to pay for disobedience. Asmodiah had seen what happened when her siblings had gotten in a bit of trouble. But rebelling against her father? It would be pure chaos.

Still, she couldn't sit idly by as her mother got herself killed. And she certainly could not help her go through with it. "Father," she sneered, feeling more courageous than she had ever been in her life "you must be out of your mind of you think I will help you in this sick plan of yours. Lilith loves you... and you only use her for your freedom! Look at what we have: all of hell to run as we please. And a family to run it with. But will your hate for humans always trump your 'love' for us? I will not let mother die. Even if the cost is you staying in your cage. Even if you find another way our of here and decide to kill me. But my mother will live."

Lucifer stayed quiet for a long time, never breaking eye contact with his daughter. Finally he sighed and shrugged, adding with an air of indifference "If that's how you choose to be, my dear, then so be it. Rebel. Fight against me. But Lilith will die and I will rise to Earth. I will destroy human kind. And when I see you... the fate that awaits will not be pretty. But you know, " he shrugged again almost rolling his eyes, "it's your choice."

Asmodiah was breathing heavy now. If she was human, she imagined this would probably be what dying felt like. Could she rebel against her father? The man who taught her most of what she knows. The man who has been leading her family since before humans developed irrigation systems. She knew if she took this step, her life would never be the same. She loved the way things were. She wished nothing had to change. She looked up at her father and he was staring her down with expectant eyes. She stepped forward on instinct, to accept the fate of a life of destruction without her mother by their side. The life they had always dreamed of, but one person short.

Recoiling at the thought, she stumbled backwards, rejecting the idea of letting her mother die. The same woman that had shown her the mercy that went against her very own nature of wrath time and time again.

"No. If my mother dies and you are freed, give me your worst punishment. It'll be what I deserve. Until that time comes, if it does, goodbye father." And just like that she was gone, rising up through the earth and looking for a vessel. A poor soul that she would convince to give over control of their body. Needing a vessel was an inconvenient side effect of being the daughter of an angel. She was always able to find at least one desperate human, however, willing to strike up a sort of deal in exchange for their body. And this time was no different. She knew she had to save her mother if it was the last thing she did.

A/N

Hi guys!

So I'm a new author on this site. I've had this idea for a fanfic for a while now and I've actually spent a few days writing out a few chapters for this story, just to get a feel of it. I've really enjoyed writing what I have so far so I wanted to share this story with other SPN fans that may also feel Castiel deserves more love.

I'm hoping to keep this story generally similar to the show in reference to the events that happen and keeping characters in character. I may change things here and there, but this story is very much still in the realm of the SPN universe.

I'd love to hear feedback as you read the story, please don't feel shy to reach out to me about anything. Thank you!
