A/N Well this is my first ever Supernatural fic, I'm kinda excited about it :D I've never tried writing one before so I hope all goes well and I get lots of wonderful inspiration! Sorry this prologue sucks, Bobby, Castiel and the Winchesters will be in the next chapter don't worry. I just wanted to start things off with Lucifer 'cause he too is pretty epic.

Well its set early season 5, a little AU I guess and will focus on the Angels. There will be Destiel at some point, also when I figure out how hahaha, but it is the plan! I will have Gabriel play a decent part too! Warnings: It will get angsty most likely because it's one of my specialities, I also like humour to relieve tension and some adorable fluff, I will try keep them all in character as much as possible and make sure none get pathetic XD

Burning Seraphim

Prologue

"It's about time the Angels pay, after what they did to you, what they still want to do to you, Master, those filthy backstabbing monstrosities," a black eyed woman snarled holding a flame lit torch letting it guide her through the dark mysteries of the path in front. The light simmered in the cave setting a fierce glow across the sandstone walls reminding the demons slightly of Hell. The cavern was spacious and eerie like nothing had entered it in millennia not even any species of bat or insect, it was just quiet. The truth was it hadn't been entered in a very long time to the point the hollow was hidden to nearly all demons and angels, that was until now.

"Do not talk about my brothers and sisters like that my child, even if so they banished me from Heaven for such an unreasonable cause of loving them all so much, they are still my family. But yes, they do deserve everything that is coming to them; my punishment did not fit the crime and for so long I have been trapped in such a brutal cage surrounded by my lesser beings. How could they do that to me? My own brethren," Lucifer discoursed striding through the near abandoned cave looking for such its hidden treasure which he knew was hidden deeply inside. After all only the archangels new its location and getting that information wasn't so hard when you lived in the home of the Kings of Torture. Now all he needed was a demon sacrifice to open the door, he already had the blood of an Archangel, another loss he was willing to make, that Angel should think himself lucky. He had human blood from the possessed host his demons were in. Besides no Angel could ever set foot in the hidden room because of the sigils to keep what was inside completely safe from any hands that were against Heaven and its army. But of course humans were not Angels and could pass through the seals to get what Lucifer so dreadfully wanted.

The grudge Lucifer had wasn't fully directed at the Angels because of course many of them were not involved in his banishing but they had all been told the story and because of God's will it became nature for them to think so lowly of the fallen Angel. Truth was he was angry at God himself; after all it was his orders that had him shot down, his orders that separated him from his eternal family, and his orders that ruined his life forever. He wanted to get back at God, and what could be better at doing that than killing his children? Sure God liked man better but the apocalypse was on its way anyway as soon as little Sammy Winchester gave in to the temptation, so why not take out the rest of the competition as well. Destroy all of God's handiwork to make him feel the pain that Lucifer himself felt when he was cast out forever with no chance of redemption.

Lucifer could feel the emanating power coming from the darkness, he knew it was close, the one item that could take out the Angels once and for all. Thinking about it logically he had very little idea why the book was created in the first place, maybe God had wanted to kill all the Angels off at some point, this simply made Lucifer angrier. Before man, before those dirty apes, the Angels were everything to God, his magnificent sons and daughters, the most supreme creation in existence. Why God wanted to dirty his hands with such vermin was such a mystery to more than just Lucifer. Still one day soon, they would all be gone just a memory of existence, Lucifer couldn't wait for that day, the day he could get his much overdue revenge. Every Angel that wanted Lucifer back in the pit was going to pay and that was a fact, because after all, they all betrayed him.

"Master are we close?" An older male asked, his black eyes skimming the passageway in front, although it was shrouded in darkness he could more than easily see past it. Centuries in Hell made night vision an essential development in the evolvement of demon-kind. Lucifer smiled sniffing the stuffy air; he could nearly smell the power of the Angels.

"I believe we are," the Devil chirped a little too happily for his ego, he paced a little faster feeling the dirt shuffle underneath his feet, the two demons beside him looked like soldiers as they neatly marched along with their master towards their fatal destination.

A few more metres into the darkness they found the cave's end, a darkened stone wall scribed with every anti-angel glyph ever devised by God. Lucifer could see them all glow distinctively in the stone, like Heaven itself shone through the cracks. Of course to the demons all they saw was patterns carved into stone that meant very little to them. Lucifer could see the outline of the door hidden perfectly in the rock, the impeccable hiding place.

"We are here my children," Satan announced raising his hands up towards the entrance of Heaven's most deadly weapon. The demons were more than excited of hearing about such a thing, it meant that they would be safe from the wrath of the Angels, the only beings in the world they feared. Angels were pure and powerful unlike demons which were just spawn of Lucifer's hate and need for chaos and destruction; they were not created by the ultimate creator so in every aspect they were inferior. Even Lucifer didn't like his own constructions, to him they were nothing but mere slaves that were to do his bidding and appose what was righteous.

"So this is it? Our salvation?" The young demon woman inquired planting the wooden end of the torch into the soft sand below so it continued to light the doorway. More than anything the demons wanted their master to be free, and to destroy their direct opposition that continued to threaten their own existence like predator and prey.

"Yes, this will be God's first punishment, the eradication of his first beings and the front line soldiers that stand in my way. I'm sorry Michael but it looks like our plans have changed," Lucifer smiled. He didn't believe in destiny anyway besides it was only created by God and at this moment God was the most hated being that was to him. Satan had enough of fighting this petit war it was about time it was finished, without the Angels there was nothing to stand in the way of the apocalypse. Sam Winchester will say yes, one day. That much he knew.

"So how do we open it?" The male demon asked looking up close to the imprinted door, there was no handle, nor an obvious way that it could be opened. The only obvious answer after that was some kind of ritual. Lucifer huffed before reaching his hand into his pocket and pulling out the fresh vial of Angel blood. He held it up at eye level and stared intently at the red liquid inside, somehow he wished this didn't have to happen, but he knew that no matter how he tried to convince his brothers and sisters that he was just a victim, there was no chance of them ever understanding. God turned them against him long ago, made him the black sheep and when any father made a rule any good child would follow without question. Unlike many of the Angels Lucifer still believed God was out there somewhere and with Michael in Heaven the other Angels had no other thought but to follow their big brother.

"Do you mind holding this?" Lucifer asked nicely holding the vial out at arm's length towards the female demon who nodded instantaneously. She held the container with extreme precaution she didn't want to drop it and piss off her master.

"Thank you, my dear," Lucifer gave her a courteous nod before slapping his hands together and rubbing them ferociously, "right time for business." Lucifer pressed his hands firmly against his back and stepped forwards towards the door and the other demon letting the seemingly inconspicuous blade slip from his sleeves between his fingertips. He hummed to himself casually looking over the engraved stone waiting for the right moment to strike. His slaves were going to die for a good cause, that didn't mean they were going to go down quietly, like any species it strives for life.

"You do know how to open it right my Lord?" The male demon asked intrigued, joining his boss focusing fully on the doorway in front. Satan turned towards his minion with a mock offense expression, "why of course I do, I am the Devil after all," he stated holding back his dark smirk. Seconds later his hand whipped forwards, slashing the demons throat with the sharp bladed dagger engraved with demon killing magic.

The female demon gasped nearly dropping the phial from her fingertips as the other demons face flashed a yellow and the bare skull of the demon inside sparked its true face. Blood poured from the deep wound and down his neck like a natural fountain.

"Don't underestimate my knowledge you disgusting piece of vermin," Lucifer smiled letting the blood cascade into the chalice in his hand. After the item was filled with the deep red poison he let the drained body drop to the floor where what remained of its life danced its way across the sand creating small rivers, decorating the floor with veins of its own. Lucifer lay the chalice down on the small stoned patch at the foot of the doorway ready for its use before turning back to his other demon. He held out his hand towards the woman whose eyes had widened at the scene before her, "now, give me back the vial," he sternly demanded. The woman looked at him distress in her face, she dared not to disobey her master but Lucifer was more than just a scary boss, she wasn't naïve enough to think that he cared about the vermin that crawled out of Hell to do his bidding but in the end he was still her leader, near enough her God.

Reaching out a shaking arm she handed vial over and quickly retreated herself back.

"Thank you, now be gone!" Satan ordered holding his hand out forcing the demon inside the possessed woman straight back to Hell. The black smoke burst out from her mouth with a screech congregating above the vessel before bursting into flames. The young woman fell to her knees heavily before quickly regaining composure. She looked up frantically at the man that stood tall before her, he held a gentle smile on his face but his eyes shone with nothing but pure hate and malice.

"W-where am I?" She asked her fingers gripping into the dirty sand, Lucifer bent down so he was eye to eye with the quivering woman directly opposite.

"Don't worry, I'm not going to kill you, only if you do what I say," he gently spoke holding his hand out to the woman much like a gentleman. The woman glanced fearfully at the offer before her before realising that there was nothing much she could do, she didn't even know where she was, let alone call for help from people that weren't even there. She placed her delicate hand into his and he pulled her softly to her feet. She wrapped her arms around herself, taking a small yet unnoticeable step backwards.

"All I want from you is a little bit of blood and then for you to go inside that room over there and retrieve a book for me," Satan explained turning his gaze towards the invisible doorway. The woman's eyes followed unable to comprehend the situation she was in, nor see the room that the scary man was mentioning to her.

"If you do this, I will let you walk away with your life, ok?" He asked keeping his voice soft yet with the underlying violent tones which made him sound twice as threatening to the innocent woman. She nodded immediately as Lucifer grabbed hold of wrist and slid the knife down letting the blood flow freely over his pale skin where he quickly collected in another chalice.

"Now, that wasn't so bad was it?" He spoke before taking his collection towards the others. He poured the human blood into the chalice of demon blood mixing them together before doing the same with the Angel blood until all three were bonded together.

"Ok now for the fun part," he jested, picking up the chalice with both his hands and headed over to the woman who cowered at the edge of the cavern wall. She clung tightly at the hem of her T-shirt which was now covered in blood and dirt.

"All you need to do is stick your hand in this blood and then open the door, you will see a pretty little symbol carved into the rock with a hole in the middle, just stick your arm in and turn the door handle," he once again explained, knowing better than to argue the woman complied instantly dipping her hands into the mass of blood, squirming at the thought and smell of what she was coating herself with. She raised her now red hand out of the liquid and stumbled towards the rock looking desperately for the hole the man was talking about. She eventually found it, the perfect size for a human hand, she glanced back at Lucifer who just nodded and she wondered why that he couldn't do such a thing himself. Reaching inside the tunnel carried on until her shoulder was pressed against the stone, the rock scratched at her skin and it felt very uncomfortable however the blood acted as a sick kind of lubricant that made it easier to get her arm down. She stretched her fingers out finding something hard that felt like a door handle, she took hold of it and felt it turn between her fingers. A sound of falling rocks echoed its sound down the hollow and the woman quickly pulled her arm out of the wall as light flashed out from the widening cracks. She covered her eyes as the stone itself moved away from the wall like a sliding door.

"Excellent!" Lucifer shouted happily looking into the now visible room. The room was shadowed out most of it impossible to see, except for the spotlight lit block in the middle which on top sat the book he searched for. Finally, it was nearly within his grasp, after so long of punishment he was finally going to start his revenge, Lucifer's black heart began to beat faster at the thoughts that overpowered his mind. After all these relentless years, salvation was finally his.

"Now go inside and retrieve that book for me," Lucifer ordered pointing inside the obscure room and once again the woman followed his request without a sound.

There was something about the room which made the woman feel at bliss, that even know she was scared half to death with what was happening around her, stepping into this chamber gave her a sense of peace. Retrieving the item ordered she quickly hurried back out feeling the wave of serenity once again leave her being making her feel once again in dreaded fear. She handed the book over to Lucifer who eagerly took hold, cherishing the feel of the gold beneath his fingertips. The book was beautiful, magnificent in fact. The front was pure gold, with a freshly polished shine, a light that would never go out as long as the Angels lived and decorated in the outline of cherubs.

The book of the Angels was now in his grasp.

"Sir, p-please can I l-leave now? I did what y-you asked of me," the woman stuttered, she held her hands together, like she was almost begging him with prayer. Lucifer frowned, how dare she!

"You did well my precious thing," he held his hand up, and bowed his head feigning kindness, a small relieved smile spread across her face before Lucifer flicked his hand and the woman could only hear the sound of her neck break before collapsing to the floor, dead.

"You filthy whore, what makes you better than me?" Lucifer spat kicking sand into the glazed eyes of the dead human below. He hated all of them. If it wasn't for them he would still be in Heaven with God, content, instead of rotting in the pit like some cockroach.

"Now, back to work," Lucifer smirked opening the book and finding the chant he needed to wipe out those who betrayed him…

A/N I hope that wasn't too boring, I decided to make Lucifer a little twofaced because in the series he can be nice and manipulative when he wants to be.

Reviews are extremely appreciated of course! It will inspire the next chapter which will have Cassy in! Wooo! I hope this fic has good potential!
