(Don’t You Dare) Let Go – G, 1k words, Merlin/Arthur Pendragon

Canon Era
Noble(’s) Wrath – M, 7.1k words, Merlin/Arthur Pendragon
“Yes, right, you deserve rest,” Galen interrupted him. His tone had gone from kind to patronising. “How would you like to rest more comfortably tonight, Merlin?”
“Sorry?”
Galen gave him a pitying look. “I mean that I would enjoy your company tonight, Merlin. Surely the prince hasn’t tired you out completely.”
It took a moment before Merlin understood what he meant. He tore his wrist out of the other man’s grip and took a step back, trying to keep the horrified expression off his face.
“I don’t serve Arthur in that way, nor would I someone else.”
Or:
A visiting noble propositions to Merlin and does not take Merlin’s rejection well. But Lord Galen’s displeasure pales compared to Arthur’s fury.

I Didn’t Know That I Was Starving ‘till I Tasted You – G, 8.1k words, Merlin/Arthur Pendragon
“I would’ve thought you knew that I would never hurt you, Merlin, but I suppose I was wrong. When we return, you are relieved from your duties as my manservant for the time being.”
“Arthur, please, I—”
“Shut up, Merlin!” Arthur had shouted, the anger Merlin had expected finally bursting out of him. “I can hardly stand to look at you without losing my temper! Just— I need some space. To … think.”

Stay With Me – M, 4.3k words, Merlin/Arthur Pendragon
“Sorcerer! Sorcerer in the court!” screamed Uther, his face red with rage. “Seize him!”
“No! Father, he saved our lives!” exclaimed Arthur.

Air. He needed air.

Day 11 prompts; Drowning, Dehydration
Canon Era, magic reveal
Burn Like Her, Burn Like Me – M, 1.6k words, Merlin/Arthur Pendragon
His magic raged inside him, fighting to break free. It was useless. Cold iron, tight and heavy around his strung-up wrists, shackled his magic as effectively as his arms. It hurt nearly as much as the whipping did.
Twelve.
A sob clawed its way out of his throat despite his best efforts.
“Finally,” drawled the man behind him. “I was beginning to worry you’d pass out before I got to hear your pretty voice.”
—
Arthur is forced to watch as Merlin burns.

Arthur’s eyes widened with panic, and he surged up towards the surface — only to have the iron grid slammed in his face, trapping him underwater. He beat his fist against it, bubbles of precious air escaping his mouth in a wordless scream.
Or:
After saving a human from drowning, Merlin is captured and imprisoned in a tank. When help finally arrives, things might just get worse instead of better.

“Congratulations, Mr Pendragon; a fine purchase.”
And just like that all air was sucked from Merlin’s lungs. Purchase. He had been sold. Bought. And bought meant—
“If you would follow me, Mr Pendragon, there are some final procedures to complete in order to finalise your transaction; Mr Aredian will see to you momentarily. I hope you brought an iron seal of your family crest for the branding?”
—branded.
——
In a city of copper and steam, the life of Arthur Pendragon takes a turn when he finds himself inexplicably mesmerised by a slave in iron shackles on the market stage. His name; Merlin.
Over the five years since his capture, Merlin has only been sure of one thing; that nobody can afford him. But then, nobody is as rich as a Pendragon.
