Summary
Gaius finally looks at his ward. This boy. The ridiculous, reckless, heartache of a man miserably sitting before him wrapped in bandages.
“Merlin, I never want to do that again.” Gaius’ own voice shakes.

Summary
Merlin, secret sorcerer, and not so secret Alpha makes a serious splash on his arrival in Camelot. Secret Omega Arthur now has to survive it.
Lots of tropes, I have no shame, and random additional characters when I felt like it. Some bits of canon but again only when I felt thus inclined; and I changed half of it. Maximum self indulgence included as standard.

Summary
Arthur Pendragon and Merlin were literally from two different worlds. One is a prince from a great kingdom and the other a common farm boy from the next kingdom over. These two should have never met.
But that was before they realized their parents were once friends and arranged the two of them to marry when they reached adulthood. That was before Uther turned on magic and Hunith went on the run with her infant son.
Now, twenty years have passed and the Prince, Arthur Pendragon is far out of his depth. After four months of marriage and learning what he has about Merlin, he knows that things need to change, but doesn’t know what can be done.
And with every attempt at trying going wrong, with mysterious boys showing up wanting to be a knight, strange physician’s trying to coerce his consort away, even stranger ladies who’ve seen to weaken Arthur’s brain, and the arrival of an odd Druid boy they need to risk it all just to get to safety…will Arthur ever get things to go right?

Summary
When Merlin is lost to Arthur in a way he cannot cope with, the prince is left shattered—adrift in a world colder and lonelier than he ever imagined. But grief is only the beginning. When Merlin returns, unchanged and without memory of being gone, or why, Arthur confronts a truth he never expected: Merlin is his soulmate, the missing piece that makes him whole. As their bond rekindles and deepens, Arthur will fight against all odds to protect the man he cannot live without. Together, they must navigate secrets, danger, and their own hearts—discovering that love can rise from even the darkest of tragedies, and that some souls are destined to be forever entwined.

Summary
All witches and warlocks are omegas, and Merlin is no exception. He's hidden his presentation since the second he set foot in Camelot, for being a warlock's mate would grant incredible power- power that people would go great lengths to possess. When King Cenred of Essetir visits Camelot, Merlin finds himself the target of a man determined to bend magic to his will.
Merlin would rather die than give his magic over to anyone but Arthur. It just might come to that.

Summary
When Merlin's magic is exposed shortly before season 2 starts, the path of destiny starts changing forever. Now on the run with Arthur, Morgana, and Gwen. Merlin hopes to convince Arthur that magic is totally good instead of him and Morgana just being an exception. Morgana, meanwhile, hopes to convince him to usurp his father. As allies are gathered and Arthur realizes the injustice in his kingdom, it looks more and more like he will have to act in a drastic way. A way he dreads.
Meanwhile, Arthur and Merlin are growing closer and closer and might just have feelings for each other. Something they probably should be better about realizing, considering the example of Gwen and Morgana right next to them.
In a land of myth and a time of magic, the destiny of a great kingdom now rests on the shoulders of four, their names: Merlin, Arthur, Guinevere, and Morgana

Summary
Merlin follows Arthur on his quest to the Perilous lands, returning not just with his friend alive and well but also a new kingdom. Magic has lost so much from the purge and the years after and the first rule of magic is that there must be balance, so it gives back. Creating the Kingdom of Oplaria, rled by King Emrys.
But Merlin is not so keen to abandon his destiny and Arthur, he spends his time between the two Kingdoms constantly torn between his friendship with Arthur and his duty to his people and magic. He is good at secret identities after all.
But with Arthur constantly sidelining Merlin how long can he make excuses to stay?
And how much will this change not only the Prophecy but also the future of Albion?This is follows the show from Season 3 episode 8 -> Season 4 episode 7 but will include storylines from other episodes.
If like me you loved all the side characters well then get ready to get a lot more time with them (especially if you love Mithian, Elena and Vivian).

Summary
Merlin has survived dragons, destiny, kings, magic-hating monarchs, and the emotional devastation of watching everyone he’s ever loved die.
So really, he thought, a simple trip to the wizarding world for tea couldn’t possibly be that bad.
He was wrong.
Now he’s somehow become the unofficial emotional support adult of Hogwarts, is being hunted by the house-elves because he keeps fixing castle structural problems himself, dealing with a basilisk situation that Merlin is “pretty sure he dealt with once already, back in the 5th century.” and trying to stop Gilderoy Lockhart from deciding that he is his "professional rival."
Merlin regrets stepping outside...

My fill for Tumblr's @merthurmicrofic prompt: Bite
Also fills my Tournament Bingo Dec 2025 squares for: Fairytale AU, Different first meeting, Excalibur, Past Tense, Third Person POV and Mythical Creatures.A great beast has beset Camelot, and the land is in need of a hero. After a lifetime of dreaming up stories I'd adventure, Merlin might just be that hero.
Based loosely on the Scottish fairytale of Assipattle and the Stoor Worm. (In some parts, VERY loosely.)

Summary
Arthur caught his sorcerer’s eye again. “If Emrys did have a simple, human identity, you wouldn’t have any suspicion who it could be, at all?”
“I wouldn't, I’m afraid.” Merlin shrugged one shoulder, seeming somewhat defeated. “I’ll look into it.”
Once, years ago, Arthur had been sure he could tell when Merlin was lying through his teeth. How frustrating it was to know that couldn’t be further from the truth.Or: In a fixed-it post-canon, word begins to get out about the godlike sorcerer Emrys who will aid the Once and Future King to unite all of Albion. This, of course, results in all the leaders of Albion beginning their attempts to win the elusive Emrys’ favor, in order to be chosen as his prophesied King.
Even as his Court Sorcerer, Merlin lives to antagonize Arthur and decides to inform the world -as Emrys- that he has already chosen his King, in a... less-than-conventional way. -

Summary
In which Merlin is immortal, used all of his free time to do things because he'd go crazy otherwise and got filthy rich like an old vampire without meaning to, hung out with Shakespeare and a bunch of other people because why not, got gifted a pretty Cadillac that he hates by a charity he'd forgotten he'd donated to, and has a too-high alcohol tolerance for his liking.
Oh, and he bought Avalon Lake.
Because "Shut up, I just like looking at this lake and no, I don't need help."
And a bunch of other mansions and estates and penthouses all over the country because "What if he wants to live somewhere else, I need to have OPTIONS."

Summary
Merlin has magic,” Uther’s words hit Merlin like a ton of bricks, the spirit disappearing as if it was never there.
Merlin closes his eyes, letting out the breath he’s been holding. He feels his back hit the door behind him, holding himself up against it. He doesn’t look at Arthur, just waits.
One breath, two breath, three breath. Nothing.
Merlin opens his eyes, looking up, half expecting Arthur to have disappeared to alert the guards. Arthur is staring at him, he is stock skill, breath coming out ragged and uneven. He looks crushed and not just from expelling his father’s spirit but that must also have contributed to it.
“Arthur,” Merlin tries, swallowing when his voice shakes with the anticipation of Arthur’s reaction.
“Is it true?” Arthur asks, his voice quiet but stern, he still holds the horn tightly in his grip by his side, his knuckles white with the force.
“Arthur I-“
“Yes or no, Merlin,” Arthur interrupts, voice suddenly louder in the empty corridor, he looks Merlin in the eye while he nods wordlessly before looking away, “you-you do. You would betray me? You?”

In which Arthur find out from spirit Uther about Merlin's magic. -

Summary
Arthur Pendragon has spent his whole life untouched—by kindness, by desire, or anything resembling real intimacy. It never mattered. Not until a certain annoying manservant came to Camelot—Merlin—who disregarded all strict royal etiquette and showed no restraint when it came to sudden, reckless displays of affection. Now, there’s something impossible in the space between them, something Arthur doesn’t know how to name—only that he aches to close the distance.

A slow-burn touched-starved Arthur Pendragon story.

Guys, there was only one bed.
Guys, some obscure quest in the cold far-up mountains made them "huddle for warmth".
Guys, they might give in to this farm fantasy of theirs.
Can't I just put all the tropes in there?
This fic is rated MSI for Maximum Self Indulgence.
