looking for a canon era merthur fic
hey guys! i'm looking for a merthur fic where merlin ran away a few years ago and arthur is looking for a court sorcerer. no one seems to be capable enough and in the end there are only 3 candidates left which quickly becomes 2. one of the candidates is an old man who, of course, turns out to be merlin. i remember two tasks they had to do: find out why gwen can't get pregnant and cure arthur of a mysterious illness he doesn't have but merlin (in disguise) diagnoses to be loneliness. it has a happy ending where merlin ends up running away and when arthur realises it's merlin he goes after him.
