Summary
(Formerly titled "Sea-Salted Secrets")
An idea that formed from the fact that Merlin was lied to about his heritage. (A heritage that I have tweaked for the sake of this story - a self-indulgent merfolk AU)
.... .... .... ....
Suddenly the doors opened and a haggard-looking Gaius was dragged in next to Merlin and brought to his knees. He was in front of Merlin, though the warlock could still see his face from where he stood.
Gaius started chanting, his eyes glowing, Merlin felt sharp pain from where Gaius’ fingers met his skin; he cried out.
Uther had to put an arm out to keep Arthur in place as light erupted from where they’d been staring. Eyes were averted as the bright beam engulfed Merlin’s frame. When the light faded, Merlin hit the ground with a thud. -

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
The knights find out that Merlin has magic - they don't take it well.
They had come for him in the middle of the night.
Merlin would have slept through the clank of chainmail, would not have woken to the soft noise of the door to Gaius’ chambers being pushed open. Only Lancelot’s bravery and kindness spared him, the knight raising his voice unnecessarily loud to call out “be careful, sire! If Merlin does have magic, there might be traps."

Summary
Merlin does a lot for Camelot and those he cares about. It’s a full time job on top of his full time job. A lot of it is stressful. Most of it is traumatising on some level. That kind of thing tends to catch up to a person.
Or, Merlin is exhausted. He collapses in front of the knights and they take him to Gaius. However, Merlin is both traumatised and very powerful. His magic needs to make sure he’s safe just as much as the knights do.

Summary
Arthur is captured while scouting Cenred's territory and thrown into a dungeon cell. He's not alone—his cellmate is Merlin, a mysterious prisoner who somehow recognizes Arthur as royalty despite his disguise, and who tries to keep spirits light even as he's dragged away daily by guards.
Arthur quickly realizes something is terribly wrong. Merlin is dying, slowly drained by strange manacles and Cenred's hunger for magic. Over days and weeks, Arthur watches helplessly as the cycle repeats: recovery, torture, deterioration. He falls for the strange, brilliant boy who jokes through agony and shields Arthur from darkness.

Summary

Summary
Merlin hisses as the harsh metal digs into his wrists. There are rumours that The Mighty Emrys, emphasis on the capital letters, wouldn’t bend to cold iron’s will…and yet. It’s hard to believe such innocent looking metal – or innocent as chains can be – could be the cause of such immutable pain. Don’t get him wrong, Merlin has been through his fair share of injuries and attempts on his life (some more successful than others, thank you immortality) but this? This is unlike anything he’s felt before.
[Merlin's magic is revealed after yet another bandit attack. Arthur doesn't react well. And as it turns out, cold iron is bad, folks! Way angstier than I expected this idea to be. Would you believe me if I said I just want everyone to be happy? No? Okay.]
