Merlin is an addict and Arthur is his drug.

Be careful what you wish for.

Obviously, it was not just any sort of egg.

Really, if Merlin had known that helping out the barmaid who'd shyly tugged at his sleeve that evening would lead to being tied to an alter in only a few gauzy bits of cloth waiting to be sacrificed to the "Great Spider-God Yezud, fo'ever praised be She of the eight-thousand eyes," he certainly would never have agreed to meet her in the nearby cave, no matter how low her blouse had slipped.

Project Runway!au, including Gaius!Tim Gunn, Gruff Arthur, and natural fibers-loving Merlin. Also featuring Chris Pine and Zach Quinto because Zach was made to be on PR.

Merlin AU: A long war during Merlin's formative years sparks in him the desire to be a Physician. And to pursue his dream, he undertakes an apprenticeship under Gaius, King Cendred's Court Physician who was formerly of the conquered Kingdom of Camelot. However, when he inevitably meets the King's Royal Hostage, Merlin comes face to face with a destiny that goes beyond his desire to be a Physician…

Arthur/Merlin temporary girl!Arthur Arthur gets turned into a woman while he and Merlin are away from Camelot, and Merlin can't immediately turn him back. He and Merlin have to pose as husband and wife, for some good reason. They weren't sleeping together before, though pining is fine (pining is a wonderful idea). Now though, they have to share a room and a bed... I'd love to see Merlin being the actively protective one for a change. (He's always protecting Arthur, but behind the scenes - now he gets to step forward and tell people off for leering at his wife. :-D)

"Arthur/Merlin, Merlin is fucking Arthur with the hilt of a sword"

Merlin tests new products for a sex toy company. Arthur is the head designer. It is his job to observe these tests, ask questions and take notes. It's all very professional and clinical, until Arthur gets hard during a session.

AU. The last night before Merlin is to leave the druid conclave and step into the position of young King Arthur's court magician, he is compelled to do the druids one last service—assuming the role of the Virgin Bride in the Beltane fertility rite of "The Sacred Marriage." The consequences are much more far-reaching than he ever could have expected.

From the fratboy!Arthur universe. What the title says.

“Okay, the rules are this: two guys act gay with each other, and the first one to back off loses.” “How is that different from regular-gay?” asked Merlin.

Merlin has a magical mishap and Arthur rather enjoys it.

Merlin as the Prince's bride.

"The castle is sweltering in the midsummer heat, stones breathing damply under the sun's height when even the air lies still."

Girl!Arthur (done amazingly well)

Arthur knows how to use words just as well as Merlin, and he knows about the magic.

Shortly after Arthur is resurrected in the 21st century, he finds Merlin's vibrator. That's it. That's the plot.
