(3/6/18)- I've had this crossover in mind for a while, mainly because I am a BIG fan of both shows. And considering that Legends' current season is all about magic and the team has visited Camelot before, why not? I just hope you readers into this as a thing. Thanks!

Yes, I am also doing three other stories that need to be worked on and finished, so just clarifying that all of these will be worked on and done proper. I can promise that!

Disclaimer: I do not own Legends of Tomorrow or Merlin. Long live both amazing series!

"Captain Lance?"

"Mmm…Ava?"

"No, Captain Lance. I'm afraid Director Sharpe has left the ship."

That got the captain of the Waverider, Sara Lance, to snap quickly awake. She blinked, breathed out, and looked around. It appeared, to her repeated annoyance, that she'd fallen sleep on the bridge in her command chair. Why was this happening especially to her, out of the offenders on the timeship?

"Oh, geez…sorry, Gideon. Guess I was-"

"Asleep?" the A.I. guessed. "No apologies are necessary, Captain."

"Thanks." She unhooked her chair strap and then walked towards the ship's command console, where Gideon's holographic face flickered to life. "What's the problem?"

"It appears that Mr. Rory is in a confrontation with Mr. Constantine in the dining quarters," Gideon relayed. "Something about mustard and ketchup, I believe."

"I'll take it. Thanks." Sighing, she walked annoyedly into the corridor to eventually find herself in the hall. Just when she'd gotten in the dining room, Sara ducked to avoid a flying bottle of…mustard?

"Hey!" Sara yelled. "What the heck is going on here?"

The agitated muscle that was Mick Rory mumbled something Sara decided not to think about. "Brit Coat replaced all my sandwich grub with his fancy magic juju. And now there's no mustard!"

"Then maybe Mr. Rory here shouldn't have gotten in the way of my morning rites, eh?" Constantine snorted while in a defensive position. "You can last a day or two without a sandwich, mate."

"Can you last without your face? Mick whipped out his heat gun and pointed it at him. His finger was a second away from the trigger before Sara forcibly lowered it down.

"Uh, no!" She responded angrily. "I get that the two of you are still settling in with each other, but we've got bigger things to worry about than a pissing contest. We're hunting fugitives, remember?"

Constantine snorted. "Exactly the reason I'm here, love. And as it happens, best excuse to not have to deal with sergeant anger here."

The comment only made Mick's face more inflamed. "Fine! At least fugitives are more dangerous." Then he stormed out of the mess room.

"What is with you?" Sara lightly jabbed John's shoulder. "Someday soon, you're going to need to learn to live with the rest of us, John, being that we're on the same ship..."

The warlock snorted again. "Like I said, I'm not a team player, love." He polished off one of his coat cuffs, gripped a cigarette, and lit it to his mouth. "I live how I want to."

Sara snatched the light out from his lips. "Well, until we come to an agreement about that, no smoking in the dining room."

"Didn't think there were smoke detectors on this bucket of junk!" he rattled when she started off on her way.

"Beg your pardon, Mr. Constantine?" Gideon broadcasted into the room. "I seem to have a well-fed garbage compactor on standby."

"Well played," the warlock grumbled. "Guess me and my smokes'll-"

The sentence was rudely interrupted when a sudden lurch sent John smashing into the table. After the ship more or less had settled, he breathed with darkened eyes and rubbed his bristling nostrils.

"The bloody hell was that?!"

Zari looked at the screen, seeing a holographic image of old parchment pieces wracked with wrinkles and other stains. The formation couldn't be correct, but then again, that most likely was the reason the timeline was in a fuss.

"You wankers woke me up from sleep!" Charlie yelled as she stormed in, wearing what looked to be retro pajamas. "Got any good reasons?"

Ray coughed. "Time quake."

"Time what? Speak up, genius!"

"Time quake," Zari corrected. "Something changed history so badly, it affected everything that ever happened. Lucky that we're still in the temporal zone."

Sara walked in, flanked by Mick and Constantine. "Gideon, what's the problem?"

"According to the timeline, the fabled city of Camelot has been burned to a crisp in the year 481. Tales report of some sort of demon that sent the city into chaos. In fact, most historical sources no longer report that King Arthur even exists. He's been replaced by the legend of the Blood Demon, a murderous cannibal by trade."

"Since when can one demon obliterate an entire city?" Ray asked out of curiosity.

"You'd be surprised, Palmer," Constantine objected. "I've faced a lot of monsters, but demons? They're the worst. They get inside your soul, twist you into a crooked version you'd never consider, and then exploit that for personal gain. So believe me when I tell you that they're bad news."

'Okay, but why Camelot?" questioned Zari. "You'd think the demon who did this would've done their homework, considering its' historical importance."

"Right…but then, none of you blokes did your homework when you broke Mallus' prison, now did you?" The warlock retorted.

Sara sighed. "That's…you know what? Never mind. Gideon, set a course for Camelot."

"Affirmative, Captain," the digital intelligence whizzed. The ship's systems chirped to life, causing the six legends to enter their seats.

"Haircut!" Mick yelled over to Ray from his spot. "You think they got some mustard back in Came-what's its name?

Eyebrows raised, Ray said, "I…well, I can't rule out the possibility of it."

"Hh. Works for me," Mick grumbled.

"Everybody, hang on!" Sara yelled from the captain's chair. The ship rocked and bolted as the effects of time pushed onto it. "We're going back to Camelot!"

In the cold of night, a cloaked man dressed in browned wrinkles made his way through the road. He was careful not to disturb the chipped cobble pavement with his walking, as he'd heard reports of bandits stalking these places. Nevertheless, he kept an open eye about him for danger; the last thing Jason-

Wait. He paused, swirling his face to scrutinize. Nobody was behind him, but small twig cracks were happening all around him. His ears could hear them, and with the training that he'd experienced before, he knew what these men were doing.

They were about to attack.

"You might as well come out, men," the man demanded wearily. "I know you're there."

A laugh passed his ears before several sets of feet, cheap leather and daggers big and small surrounded him. The leader, obviously the one with a greyed beard, stepped forward. "Not bad, peasant. Nobody tends to hear us when we strike."

"Then I guess I'm not nobody."

The rest of the man guffawed, but the leader remained stern. He grabbed a long dagger from his rib and dangled it at the stranger. "You know what we want. Give it here."

He wasn't about to give them that, especially since he'd come so far. "Sorry, but you seem to be mistaken. I'm heading to Camelot. And judging by the fact that I don't own a horse, I'm penniless."

"Camelot? What business you got with Uther?" Another robber wisecracked.

"Shut it!" The leader demanded, and the robber obliged. "Give your money here, man. We won't ask again."

That was it. They'd both had enough.

"Sorry, but you might want to talk with him about that," the stranger added.

"Him? Who's him?

At first, the robbers assumed the man was purporting more nonsense. But then out of nowhere, his arms and legs began to crack and contort until he was bending backward in pain of some variety. His skin darkened in color, his eyes lit up, and a voice that had to be from hell followed.

"Hello, gentlemen. Are you ready for the end of your lives to begin?"

A/N: Thank you for reading! Please review, favorite, or follow if you'd like! I plan on making a decent crossover here, one of many that will not be part of the "Potluck" anthology, and i plan on drawing well from both shows's continuities for it. I can promise that the mysterious man is a DC character and has a peculiar connection to somebody from Merlin, but whom? Feel free to shoot off guesses! And til' next time!
