The story takes place right after the season 10 finale, after Dean killed Death, the Mark of Cain was removed and Darkness was released into the world. I mentioned before, new characters will be added and thrown in the story and I will bring back several former characters from the show in the upcoming future.
Chapter 83 The Epic Battle Against Darkness
The angels stood outside their headquarters now alongside the band of demons to help them in their battle against a threat to both groups prepared to battle it out against the army of Darkness's human-figured soldiers that it had taken form to battle against them. Now it seemed to be many of them, all black-eyed and dressed in black and all of them looked identical to the other. Lucifer stood out in front with no signs of fear but mad rage now prepared for the battle. Hannah who was standing near him turned to say something to him.
"Not you Lucifer you have to stay out of this battle, since we can't afford to risk your life as we need you to bear the Mark" she told him.
Lucifer turned to Hannah with an angry look on his face.
"No, I refuse to hide out any longer and I'm not hiding out in this battle!" he cried.
"Brother, Hannah is right, we can't risk you being killed since we need you alive to bear the Mark, as it is we know we can't kill Darkness, so our only chance is to weaken it enough and you can consent to our Father to receive the Mark without it being able to destroy you or a whole lot of us. Either way some of us may lose our lives in this fight" Michael replied.
Lucifer still stood there with scowl look on his face.
"I'm sorry Lucifer, but you cannot take part of this battle, you'll have to remain behind" said Hannah.
"I said before I will no longer hide like a coward" Lucifer railed.
"Please Lucifer if you really want to defeat the Darkness it is of dire importance that you do so you can receive the Mark, this isn't a time for a debate, you said you wanted to help this is the only way you can!" cried out Castiel who was getting impatient with Lucifer's pride and ego.
Lucifer just gave a look like an angry child who had no choice but to obey. Finally gave in.
"Fine, alright we just got to beat this Darkness once and for all" he said in a huff.
"We will" said Hannah then she turned to Metatron who was standing among the crowd.
"That includes you too Metatron, you have to stay behind as well, since you're human now you don't have the power to help us fight" she told him.
Metatron just glanced like a sad little puppy feeling left out being reminded that he is no longer part of the team. "Fine" he just said.
"Oh, don't be so down the dumps there mopey, not everyone is cut out to fight, plus you can have me for company" Lucifer said to him in a snarky tone which just annoyed Metatron more.
With both Lucifer and Metatron now out of the way, Hannah stood out in front and prepared her army looking quite bold and fearless as they faced Darkness's army which was now growing as more soldiers were taking form they were now so many to lose count.
"Okay, this is it, is everybody ready?" she asked.
Everybody just nodded or said yes as they were anticipating this for while now.
"Now when I say charge we charge them okay!" she cried out again.
Again, everybody agreed.
"Okay now charge!" yelled Hannah as loud as she could.
Then within seconds it happened. The angels and the demons charged at Darkness's formed army as the angels glowed bright light and soon in a stream of light they were all over Darkness soldiers wrapping themselves around them in a stream of waves covering them with their bright white light. As for the demons including Crowley they exited their human vessels in waves of black smoke and joined the angles as the black smoke surrounded over the bright light of the angels over the Darkness's soldiers. It was a sight to see as both the bright light of waves of the angels and the waves of black smoke of the demons were now surrounding themselves around Darkness's army covering them entirely while there was a huge gust of strong wind outside that sounded like a hurricane.
The whole time, Metatron stood just outside the building in amazement at what he was seeing as he felt the huge gust of wind slap at him causing him to cover his face as something nearly got caught in his eyes. Lucifer just stood with a smile on his face not phased at all by the strong wind. He could see that it was working, Darkness was actually weakening a bit although he knew the angels and demons couldn't hold the entity off forever, they will eventually grow exhausted and Darkness will regain its strength again possible destroy all of them but at least it bided him with enough time. Then seemingly on cue, he knew the time was right and just looked up at the sky and holding out both is arms.
"Father, I consent, give me the Mark!" he cried out into the sky.
For a while nothing seemed to be happening and Metatron was beginning to worry if God was going to do anything afterall.
"Father I say to you again, let me bear the Mark of Cain!" cried out Lucifer again still looking up the sky with his arms lifted up almost like wings.
Nothing happened at first and Metatron was about to say something when suddenly it happened. There was a sound of thunderstorm in the sky and suddenly a ray of lighting came down from the sky and struck Lucifer's left arm and within moments the Mark was forming on Lucifer's arm as he just stood there in the same position now with his eyes closed unphased by the slight pain. The Mark of Cain continued to take it's form and at the same time the waves of bright light of the angels and the black smoke of the demons stopped their attack as the black smoke returned to their human vessels and the waves of bright light flew back to where they were and formed into the angels again since they felt the change happening. The change was that the Darkness's army of soldiers had disappeared into large black smoke just like when it was first released like a twister in a tornado. It was heading further away from them altogether and when the Mark of Cain was completed on Lucifer's arm, the waves of black smoke suddenly melted away into the ground not before causing some destruction including knocking down trees nearby. And before everyone knew it, it was quiet again only there was something totally different.
Although the sky was still dark since it was nighttime, they all noticed something different about the sky, as the looked out and saw the stars and the moon. The dark wasn't as dark as it was before, instead it just looked like an ordinary nighttime sky before the Darkness came. That's when it hit them that Darkness was gone, truly gone locked back away again where it can't harm the planet anymore and the planet is now free from it's chaos and destruction. Now they are all safe again every last one of them. Hannah was the first to speak up as she kept staring at the sky with an astounded look on her face.
"Oh my, look at that, Darkness is gone I mean really gone and we did it we won!" she cried.
Then the angels and both the demons cheered in their rejoice.
"We won, we beat the Darkness!" they chanted all so overjoyed hugging each other and shaking each other's hands forgetting that for moment that they are enemies.
Hannah and Castiel hugged and she planted him with a kiss on the lips that made them both blush. Michael, Raphael and Gabriel/Trickster hugged each other in excitement.
Crowley shook Castiel's hand. "We did a good job there mate, I sometimes think we would make a perfect team" he told Castiel.
"Let's not get overboard but yes we defeated the Darkness together" said Castiel.
"Hey, I was the one that bore the Mark again" reminded Lucifer who had walked over to the crowd and lifted his arm showing off the Mark of Cain.
"So, I say I should get a thank you for stopping Darkness" he said in an arrogant tone.
Although Castiel didn't like the idea of being grateful to Lucifer he had to admit to himself Lucifer was right, if he hadn't come out of the woodworks after all this time to agree to bare the Mark of Cain again than the Darkness would still be on earth causing more destruction until it finally destroyed the whole planet out of revenge against God.
So Castiel just swallowed his pride and walked over to Lucifer and said, "thank you Lucifer, we couldn't have done it without you".
"Yes, thank you Lucifer, you did come through in the end" said Hannah with grateful look on her face.
Then the three other archangels came over to Lucifer to thank him. "Yes, well done brother" said Michael.
"We thank you dearly" said Raphael.
"Me too" added Gabriel as all three of them patted him on the shoulder and for that moment all four archangels were together again on a united front celebrating together for defeating a common threat to them and the world.
Others also came over to thank Lucifer treating him like a hero as Lucifer just lapped it up. Of course, the angels still didn't trust him and Hannah and Castiel both knew for sure that Lucifer had an agenda and they weren't going to just ignore that in their moment of rejoice.
But right know and that exact moment, the enemy was now an ally a hero to them all as the foes were now celebrating their mission accomplished which was finally after all this time, ridding the world and themselves of the one huge threat to their very existence and none of them will ever forget this event when angels and demons fought alongside each other to defeat their biggest enemy of all which was the Darkness.
