Authors Note: I'm new to all of this, and some of the source material might be a bit fuzzy. Constructive criticism/character adjustments are more than welcome. I've also only seen up to the finale of Arrow season three so I'm keeping it vague where time is concerned.
Also I don't own any of the properties discussed here, yada yada yada don't sue me please.
"Your world is not the only one that is in danger Oliver Queen."
"Wait, come back. What does that mean?"
"If you survive this, it will be the start of something great."
Oliver Queen awoke with a start, sheets drenched in sweat. He ran a hand over his close cropped blonde hair. This was the third time he'd had this dream in as many days. A deep voice warning him of something, an overwhelming sense of impending doom. Oliver liked his threats where he could see them, well within striking distance. He sighed heavily and climbed out of bed, dropping into a cross legged seated position. He took a deep breath and closed his eyes, trying to clear his head. After a few minutes he shifted as if in annoyance.
"Barry, come on. You're about as subtle as a freight train." He said. The grinning scarlet speedster stepped into the early morning light, an incredulous look on his face.
"I am never gonna understand how you do that man." He said laughing. Oliver climbed to his feet, a jovial smile on his face.
"You ran up the building Barry, that tends to rattle the windows a little bit." He said. "Come on, Thea usually makes coffee before she leaves for work, I'm sure she left some."
Barry was seated on a stool waiting when Oliver made his way to the kitchen. He gestured to the pot of coffee before pouring himself some. Barry shook his head.
"So you couldn't sleep either?" Oliver asked finally.
"No I keep having this bizarre dream.." Oliver's full attention was on him in an instant.
"What kind of dream?" He asked.
"There's this dude with a really deep voice, I never see his face. He says-"
"Your world isn't the only one in danger?" Oliver finished. Barry sat bolt upright.
"EXACTLY!" He said excitedly. He deflated just as quickly as another thought hit him.
"Something bad is coming isn't it?"
"If it is, we're gonna be ready for it. I don't want to worry everyone yet but let's call a meeting just to be safe. Get in touch with Cisco and Caitlin. I'm going to get a hold of Digg and everyone here. We'll meet at Verdant alright? As soon as possible. You may want to grab some bags in ca-" A hard gust of wind stopped him. Barry was now wearing civilian clothes and carrying a suitcase.
"In case this takes a few days? Awful sweet of you to let me crash here."
"I was going to suggest a hotel but this works too." Oliver said with a smile. He pulled on a jacket and started rummaging around for his motorcycle helmet.
After a series of cryptic phone calls, everyone is assembled in the darkened "Arrow Cave".
"So everyone had the same dream?" Barry broke the tense silence. Around the room people nodded hesitantly.
"Down to the syllable." Felicity confirmed.
"Well not everyone…" Cisco grumbled. Caitlin shot him a sharp glare.
"Someone is targeting us then." Diggle said.
"We haven't encountered a metahuman capable of infiltrating dreams before." Caitlin said warily.
"So…" Oliver started slowly. "Normally I would be the last person to suggest this, but after what the Lazarus Pit did for Thea, is there any way we might be able to look into a supernatural explanation for this?" Diggle shot him a strange look
"We don't know what that was. We don't want to start going down that path unless we have a firm place to start." He said. Roy nodded in agreement, just grateful to be back and involved again.
"I just don't want to leave a stone unturned here." Oliver said. A dagger dropped point first into the table, as if it had been dropped from the ceiling, pinning a piece of yellowed parchment to the table. The room burst into motion, Oliver and Roy drew their bows and had them aimed in an instant. Diggle joined them, handgun drawn.
Felicity reached for the note.
"Don't touch it!" Oliver hissed.
"Whoever delivered this very clearly could have killed us already, it would be a waste of effort to booby trap the note wouldn't it?" She shot back.
She stared at the note in her hands for a long second.
"I am being watched, I can't talk at length but allies are coming to bolster your forces for the journey ahead. Trust in them, trust in the door….Signed Fate." She read out loud.
"Fate? This is getting bizarre Oliver." Diggle said
"Roy and I are going to start patrolling regularly again until we figure this out. Felicity I need you to get in touch with Ray, take Cisco and Caitlin, try to figure out some way to track new arrivals to the city. Whoever these allies are, they have some serious questions to answer." Oliver said firmly.
"Are we just going to ignore the dagger that fell out of nowhere?" Cisco asked incredulously.
"We've seen weirder Cisco." Caitlin said ushering him out of the room.
Elsewhere…..
"Dean Winchester, your world and many others are in danger."
"Cas? Damnit Cas, just call me, stop appearing in my dreams."
"If you survive, this will be the start of something great."
Dean Winchester awoke in his darkened room with a start. He eyed his room warily before tightening his grip on the knife under his pillow.
"That wasn't Cas." He muttered to himself. He climbed out of bed and dressed quickly. A knock at the door had his handgun up and trained in an instant.
"Come in." Dean said calmly. Sam entered, hands raised as he soon as he saw the pistol. He showed him the knife he had in his hands and placed it calmly on the floor.
"Prophetic dream?" He asked.
"Prophetic dream." Dean confirmed. He put down his pistol and went about lacing up his boots. "I'm going to put out the call to Cas. Maybe he can make some sense of this." He said.
"I cannot. I heard the same message. Which should be impossible." The gravelly voiced angel looked concerned. Dean, startled at the angel's sudden appearance, lunged for his sidearm again. He got up grunting angrily.
"I'm never gonna be used to that bullcrap as long as I live." Dean said grouchily. Sam just chuckled and walked out towards the common area of the bunker with Castiel. Dean stumbled out after them.
"So you're telling me, whatever this is managed to hack angel radio?" Sam was asking.
"It's not that simple but yes." Cas said. "It's a feat that should really be impossible."
"So I have a better question…" Dean said. "Why is it always us? Why the hell can't Bob the fucking accountant hear the voice of God for once? I could use a vacation." He popped the lid off of a beer.
"It is the best that ones with the tools to do the most good heed the call." Castiel said. Dean grunted, flopping heavily into a chair. Sam walked back into the room, an open book in his hands.
"Lore is coming up empty. We might be here a while." Sam said.
"I'm worried we haven't encountered this before. Most things with a grudge against us and enough power to break the warding around here are very dead." Dean said.
"That we know of Dean, that we know of." Sam said tiredly, moving more books onto the table. A thumping noise sent the trio running towards a desk near the front entrance. A solid gold dagger had pinned a piece of parchment to the table.
"Awh what the hell?" Dean said angrily. "This better not be witches." He drew his pistol again. He mouthed "I'll cover you." At Sam. The taller Winchester brother advanced cautiously to the table. He picked up the note.
"How far would you go to save lives? If your answer is what I expect it to be, enter the forest to the southeast when the sun goes down. Many innocent people need your help, potential allies as well. Trust the door. Signed Fate." Sam read out loud.
"Fate? Whoever this has serious delusions of grandeur." Dean snorted.
"We're going right?" Sam asked.
"Of course we are!" Dean said, already walking towards the armory.
"What if it's a trap?" Sam yelled after him.
"It's always a trap!" Dean shot back with a cocky grin. He was just excited to be back in the game again. Idle time did not sit well with Dean Winchester, despite all of his begging for a vacation.
A few tense hours passed, Sam learning everything he could about Fate. Dean sharpening knives and packing shotgun shells. Sam glanced up to see his brother carving stakes, he raised an eyebrow in question.
"You never know." Dean shrugged.
"It's time." Cas said, reappearing. They exchanged a look, Dean swept everything into a duffle bag and followed Cas out. Sam closed a book and followed after. They head for the impala first. A piece of yellow parchment is pinned under the windshield wiper.
"The journey must be made on foot. Your car will be waiting for you on the other side. Trust the door…Fate." Sam read.
"If he hurts Baby, I'll take his arms off. I don't care if he turns out to be God." Dean said. Grumbling and grousing the whole way, Dean followed Sam into the forest. A gold band gleamed dully in the reflection of their flash lights, hanging from a tree arching over the path.
"This must be the door then." Dean said, eyeing the archway suspiciously. Sam nods. Dean takes a deep breath and walks through. The forest is dense and shadowy, branches whipped at the brothers faces as if they were living things. Cas led the way, angel blade drawn. They emerge from the forest at the edge of a highway. As promised the Impala was there, keys in the ignition. The brothers and the angel remain wordless except for a few significant glances. They were dealing with someone who was very powerful. They start driving the way the car was pointed and quickly pass a road sign.
"I don't think we're in Kansas anymore." Sam said. Upon reading the sign.
Starling City, 2 miles…
