Summary
Gaius ushers them in. “I was just gathering my things to come check in on you. How are you feeling?”
“Uh, headache. Deeply wrong.” And then Merlin adds offhandedly, “Oh, and like I’ve switched bodies with the Crown Prince of Camelot.”
Or: Merlin and Arthur accidentally swap bodies. This would be a great opportunity for Merlin to relish in making Arthur muck out the stables, if the prat hadn't also gotten Merlin's magic in the exchange.

Summary
When Uther Pendragon seeks out and begs Nimue to bless him with an heir, he did not realise the consequences would leave him with a dead wife and a son that possesses magic.
Arthur Pendragon has spent his life trying to be the perfect son, the flawless prince, the man his father demanded he become. But deep beneath his armor lies a secret he doesn’t understand, a power that burns in his blood and answers to his heart. A power he’s been taught to fear.
But destiny has other plans. As Camelot trembles beneath Uther’s crusade against magic, a young sorcerer named Merlin arrives with secrets of his own; and an unshakable belief that Arthur’s fate is entwined with the very thing he’s been taught to despise. As their bond deepens, so too does the truth between them, blurring the lines between friendship and something far more powerful.

Summary
What if it was Arthur that knew about the destiny to the full extent, not Merlin?
Merlin is not just a wizard, anymore than Arthur is just a boy. The most powerful sorcerer to ever walk the earth, who could rival Dumbledore at such a young age is destined to protect and help Arthur unite the lands of Albion and bring peace to muggles and magic folk, joining them like they once were. Without Merlin, Arthur will never succeed or become king. Without Merlin, Harry would never live long enough to defeat the dark wizard that is Lord Voldemort.
If he finds out, exactly what his destiny is, that could be disastrous for everyone involved.
When Arthur first comes in control with Merlin, their magic collides in a negative way as they both intended ill-will on the other person. It was then that Arthur understood what was truly at stake.

Summary
A flash of terribly familiar golden light filled the clearing, a deafening boom sent the knights flying backwards, and then, at last, a pair of blue eyes opened once more.
And they were met in return with the sight of shimmering gold eyes.
As it dawned on everyone what exactly had just happened, Arthur’s battle-proven instincts kicked in and overtook his petrified mind once more, playing out his body’s natural response to any worst-case scenario:
Grab Merlin and run.
~
Alternatively: After a ritual goes disastrously wrong, Merlin's magic has been transferred to Arthur, who is still unaware that Merlin has magic in the first place. Believing himself to be a danger to everyone around him, Arthur sets out to live the rest of his life in self-imposed exile.
Suffice it to say, Merlin has some objections to Arthur's plans. -

Summary
Originally posted on FFnet in 2015.
Original 2015 Description:
"Y-you said you would come back."
"I know. And I did."
"N-no, you didn't."
Arthur needs to face his biggest mistake.
Updated 2025 Description for Ao3**:
Arthur can't take back what he did to Merlin. Gwen won't speak to him, his knights have lost their faith, and Morgana's army marches ever closer to Camelot, but Arthur can't undo what he's done, even though he desperately wishes he could.
With his sins laid bare for everyone to see and Merlin fighting for his life, Arthur must walk the path of atonement.
**updated description, but don't worry, this story still has all the typos and grammar problems you knew and loved from 2015! Just for you! I have not fixed any of them! Even though I really wanted to and might eventually publish an edited version in the future!

Summary
A silent nod was her only answer. She frowned slightly. “Uther, promise me you will protect our child if anything happens to me. Promise me you will love them and raise them to be kind and good-hearted to their people.” Her voice rose slightly in pitch. Her eyes were bright with a look that Uther would never be able to get out of his head.

Summary
Mordred’s gaze stared at him blankly, all fight and emotion drained out of his body, his visage more akin to that of a corpse than a young boy. “It’s you, you’re the king from the prophecy.”
Arthur blinked. That made even less sense. “You must be mistaken.”
“I’m not. Emrys chose you, the Druids know it.”
“But wouldn’t I know?” Arthur narrowed his eyes. “This seems kind of important. I think I would know.”
Morgana intervenes early and Arthur winds up captured on an Angle ship with Mordred for company. Neither of them is particularly enthusiastic about this, but with Morgana's presence growing and Mordred's hands in iron chains, Arthur may be forced to face realities he did not wish challenged and use methods he condemned - even magic.

Summary
The Dueling Club met Friday evening.
Arthur was already setting up when Merlin arrived, late as usual, expression gleefully unhelpful.
“I’m here for moral support,” he said, conjuring a chair from the floor and sitting in it sideways.
“You’re here to make my life difficult,” Arthur muttered.
“Same thing.”
Or…
Arthur and Merlin get a job! At Hogwarts, for sword-related purposes.

Summary
Merlin had failed. Despite all his efforts, Arthur had ended up dead in his arms on the shores of Avalon, so close to salvation. Surely, this could not be how their shared destiny was supposed to end? No, it was all Merlin’s fault—he had made all the wrong choices, misinterpreting prophecy after prophecy. If only he could go back and try again, now that he knew better, maybe he could right his wrongs. Maybe he— Oh. Maybe he could go back…
Ignoring Kilgharrah’s protests about the impossibility of what he aimed to do, Merlin let all his power loose, becoming one with the fabric of the world and the magic he was born of. After following the bond he shared with Arthur through the winding paths of time, he finally emerged a decade into the past, having successfully seized a second chance to get this whole destiny thing right. Unfortunately, he would have to win Arthur’s trust all over again, seeing as Merlin was alone in remembering anything of the future he was hoping to change. Or…was he?
