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 8 Getting Together.
Time had passed on and both Gwen and Madame Bess and taken time to process what they had been told. The Winchester brothers were hunters of monsters that exist in the world of angels, demons, witches, vampires, werewolves etc. The Mark of Cain that was given to the Devil who gave it to the Biblical Cain who had been living all this time as some immortal and now Dean had the Mark until it was removed by witch. Because of its removal now this Darkness which they both had visions of is some evil entity meant nothing but destruction until God locked it away has been released.
It took some time for them to get over all the shock of it all even now it they knew that this Darkness was something bad that would affect the world somehow but this was too much. Sam and Dean also had to process that two strangers, a grandmother and granddaughter psychic duo had predicted this Darkness in their visions, in the cards and even had visions of them, their car, the bunker and spirits told them their names. They weren't fazed at all by them being psychics since they encountered their fair share, but they hadn't met any who could predict the Darkness was coming. Now all of them are in the library discussing on how to deal with all this.
"So, is this Darkness going to destroy the world as we know it, I mean other it causing the world go dark what could possibly happen?" asked Gwen still shaking up by all of this.
"We wish we knew, I mean we just don't know what we're facing" said Sam.
"What about you, you're an angel, can't you contact God for help?" asked Madame Bess looking at Castiel and Hannah.
"This Darkness is more powerful than any of us has dealt with, God has already instructed me to round up an army to help in its defeat" said Hannah.
"An Army?" asked Madame Bess curious about all of this.
Sam quickly interrupted.
"This whole thing is the biggest thing we dealt with that's all we can say" he said.
"I still wish we had gotten here sooner, since I was the one that first saw it in my premonitions, then maybe" said Gwen but before she could finish Dean spoke up.
"Hey, there this isn't your fault, it's ours, we did this, there wouldn't been anything you could have done no matter what so quit your fretting" he exclaimed.
"I know but somehow I can't help feel somewhat responsible since I predicted," she finished.
"The young man is right dear, you couldn't have possibly known how to stop it no matter how much sooner we got here" said her grandmother.
"But maybe with our abilities we may be help predict what will happen next and how to defeat this thing" said Gwen.
"No, we don't want you two involved in any of this" said Sam.
"With all due respect young man, we are already kind of involved being that we saw some of events before it happened, it you all like I can even hold another séance to ask the beyond on how to stop this" said Madame Bess.
Then Hannah spoke up again, "I think this would be the time to speak to all of you alone" she said turning to both Sam, Dean and Castiel.
"All right, would you excuse us ladies" said Dean leaving their two guests alone in the library.
After going to another room further away so that their two guests wouldn't hear, Hannah decided to address them about the rings.
"As I said before, God as sent me on mission to round up an army of angels down here, including the archangel as we need all the help we can get. That also includes Metatron whom you help escape from our prison" she said.
Sam, Dean and Castiel all looked uncomfortable and a bit guilty.
"No need to worry, as we can't focus on that knowledge right now, our priority is defeating this Darkness" she continued.
"You said the archangels, but both Raphael and Gabriel are dead" replied Dean.
"God had Raphael resurrected and taking a new vessel and as for Gabriel, it's been reported he's not dead after all but alive and hiding somewhere" said Hannah.
"What, Gabriel is still alive!" said Dean stunned.
"Yes, plus, I have to inform you that God has also instructed me to had Lucifer's cage open and in order to release both Lucifer and Michael" she continued.
"What!" both Sam and Dean cried at the same time.
"Wait, there's no way in hell you can release Lucifer from the cage, not after everything we went through to shut him back in there" said Dean lowering his voice so the two women wouldn't be able to hear.
"I'm aware of your reservations about all of this and understand but this is what God has ordered himself as it's the only way to help get rid of this new threat" Hannah explained.
"Well you ask your God where the hell has he been all this time and why now is he so concerned about saving the world that he would want to release Satan in the world, isn't he also a threat to humanity the last time I checked" said Dean angrily.
"This threat is bigger than anything we've dealt including Lucifer, hard decisions have to made during this new crisis including releasing Lucifer as we need all the help we can get, there's no way around it" said Hannah.
"Castiel, please you all can't let this happen" Sam finally spoke up.
"I feel the same way as you guys do, but there is nothing I can do about it, Hannah is only following orders, we don't have a choice besides , the plan is to send him back into the Cage after the ordeal is over" was all he could say.
"And I need to ask you for the four rings of the horsemen to open His cage" said Hannah.
Both Sam and Dean were hesitant until Dean spoke up.
"Well, three of the rings are buried in Bobby's Salvage Yard, but as for Death's ring, I gave it back to him in order to get Sam's soul back but now there is a problem".
"What is the problem?" asked Casitel.
"Death is dead" said Sam.
"What!" this time Castiel and Hannah cried out at the same time.
"That's right, I sort of killed him" said Dean.
"You did what, how?" cried out Castiel shocked at such a thought.
Dean and Sam told them the whole story which both shocked and angered them.
"I can't believe this, do you two have any idea how much destruction you might have caused!" yelled Hannah who was more annoyed at them now.
"It was all my fault, I was the one that ganked Death" cried Dean.
"Dean, you can't just kill Death and not be some consequences, we don't know what this means but it could lead to another chaos, Darkness being released its bad enough" said Castiel.
"Cas, I regret everything, I know I made a mess out of things" cried Dean remorsefully.
"Same here, we both are at fault for everything and we don't know what to do" said Sam.
"You two have done enough, just tell me the location of where you killed Death so I can retrieve his ring" said Hannah. was was still angry.
After telling her where they could find it, Dean made a request.
"Hey Hannah, although this is a lot to ask but when you do open Lucifer's Cage and release Lucifer and Michael, could you please have Michael release our brother Adam, and take another vessel".
The only good thing they could thing opening Lucifer's Cage is seeing their long lost half-brother Adam again, although it's been five years.
"That I can do" said Hannah.
"Thanks" said Dean.
Then Hannah teleported within seconds and was gone leaving only the remaining three in the room still figuring out their next move.
"Hey guys, what are we going to do about Tangina and her granddaughter over there?" asked Dean sarcastically.
"I don't know, but one thing for sure we can't just send them away" said Sam.
"Why the hell not!" said Dean who was frustrated enough with their presence.
"Because, we don't know what that Darkness is and how much damage it will cause. We were lucky to get back here as it is, but now that this thing is here, who knows what it will do. I mean this could be like the apocalypse or worse, something could happen if we sent them out right now" said Sam.
"So what is you solution, let the psychic grandma and granddaughter duo move on in?" Dean asked half-joking.
"I just feel it is best that until we figure out what will happen next now that this Darkness thing is here, that we put of with them for while, I will feel guilty of they leave and something bad happen to them" said Sam.
"Sam is right Dean, we don't how dangerous with the Darkness everywhere" said Casitel.
"I wouldn't feel good sending them away right now either" Dean admitted. "But, you know we can't involve them in any of this, this is too dangerous" he continued.
"I know, I know Dean, we won't but if they get another premonition or something we can't just ignore either" said Sam.
With that they suddenly heard a cry the other room the trio took off running back to where Gwen and Madame Bess were.
"What's happening!" cried Dean.
"My granddaughter just got another vision" said Madame Bess.
"Gwen what it is, did you see something else, does it have to do with the Darkness?" asked Sam.
Gwen looked up at everyone with frightened look in her eyes.
"You got to save her!" she cried.
"Save who?" asked Sam.
"A red-headed woman will be shot in killed in that crowd right here in town, please you got to save her!" was all she could say.
