"Urgh, I'm never going to get used to that" Dean hurled bending over, cupping his knees for support. His head spun wild at the floor below him as he struggled to regain his balance. "Where are we?" His partner donned in an old trench-coat dreamily looked to the sky before quietly surveying their surroundings.

"Albion"

"Albion?" Dean huffed before standing tall, "I thought we were heading to Camelot?" Thin wood enclosed them both; on the horizon greeted a colossal castle adorned in morning light.

Cracking of branch under foot sent them spinning as a pair of blue wide eyes stared back. Short dark hair lightly brushed over his pale shock-stricken face.

"You..?" the mouth lolled as it tried to form words. They watched helplessly as the gears in the boys' head turned, trying to find a way to process what he had just witnessed.

"Oh crap" Dean hissed, searching for some plausible excuse for their sudden unexplained arrival.

Dean growled through grit teeth as the boy scrambled towards them in a desperate rush. Reflexively grabbing his knife in defence, before quickly reminding himself he was dealing with a human.

"You can't be here, someone will see you" the boy hushed yanking Dean by the elbow,

"What?" Dean hissed as he was dragged behind in tow.

"Just follow me!"

"Here!" Sam smiled breathlessly at his computer screen as Dean took another sip from his beer can. After only hours of research their hotel room had already become littered with paper and books; fruitless attempts at solving their latest case.

"Great, what is it?" Dean rose from his seat to shadow his brother, reading the page over his shoulder.

"Chimera; ancient Greek mythology" Dean cringed at the symbols and images on the page, the largest depicted a three headed beast of Lion, goat and snake carved in a bronze dish.

"Greek? Then what the hell is it doing in Wyoming?" Four hours driving had his eyes struggle for focus. With the palm of his hand he rubbed his them free of the glare of the screen.

"Migrated? I don't know"

"Then how do we kill it?" Sam scrolled the page, skimming with the very little Greek he had studied before joining Dean in hunting.

"Uhhh, says here, only an enchanted sword can kill a Chimera" Sam muttered incredulously at the website, beginning to doubt its credibility and his Greek.

"Enchanted? Enchanted like magic?" Dean blurted, annoyed at the heavy complications this job had suddenly undertaken.

"Enchanted, as in, engulfed by dragons' fire" Sam retorted in a flat smile.

"Dragons' fire?" Dean echoed, taking a deep swig of his beer, "Is there anything else we can use? Salt, steel, ram horn, jellyfish tongue, something?"

"Jellyfish don't have tongues" Dean glared at him as Sam returned to his laptop, "Steel will burn but other than that…"

Dean hacked an exacerbated sigh before taking notice the new entity that had silently appeared the room.

"Any ideas Cas?" The third party had placed himself at the end of one of the untouched motel beds; of course 'party' wasn't the right word for the dark faced, motionless sack. "Cas? Hey!" Dean violently waved a hand in front of his face before Castiel finally seemed to realise where he was.

"Enchanted swords, what do you know?" Cas's thick eyebrows pinched together in thought.

"I know only of one" he talked to the floor, folding his fingers together "Excalibur"

"Excalibur? Like the one King Arthur, Excalibur?" Dean bit his lip, nodding slowly, he had heard of more impossible solutions, "Alright, then how do we get it?"

"It was tossed at the edge of Avalon, and is now guarded in the treasury of heaven…" he sat back on the bed before finally looking up at Dean, "I can't go there"

"Plan B?" Silence filled the space as Sam went back to the keys on his laptop, pausing at the Google results which offered not much help. His mind reeled with reports and photos of the victims that hung the walls around them. They had to act quickly, four people were already dead and a handful more had claimed sightings.

"What if we took it and gave it back?" his thoughts had effortlessly slipped off his tongue only to be sneered at by his older brother.

"What? You mean go back and take it from freaking King Arthur? Imagine that conversation! 'Excuse me; may we borrow your sword? Who us? Oh, we want to kill a three-headed monster in the freaking future!' Sam are you nuts?" Sam nodded as he tried to picture the scene, before shrugging indifferently,

"We've done it before" Dean mindlessly scratched his chin, he couldn't argue with that. They had jumped more lifetimes than Dean could count. Visiting their mom, talking his dad into buying the Impala and even to a future where Lucifer was wearing Sam like a cheap suit.

"What do you think Cas?" the growl licked at Cas's spine, making him twitch a little. It was a hard sensation to explain because even he wasn't sure what it meant.

"It's possible but…"

"But?" Cas sighed, squaring his shoulders of the invisible weight on them; of letting Dean down.

"My power is vastly depleted," his voice grim in dark thought before looking at them both in turn, "I can only take one of you"
