looking for fic
Hi! I'm trying to find a Merlin fanfic where Merlin and Arthur are in the woods, and Merlin has to use his magic (i can't remember if he already did a magic reveal or not) but each time Merlin uses his magic, he gets weaker and weaker, until some old man appears, and has Merlin do some type of tasks. Eventually, Merlin starts doing magic correctly, in Welsh (I think) and he survives. Please help me if you can!! Thanks!
