Secretly royal or noble!merlin

[ascello]

Hi, 
I'm looking for fics, where Merlin is royal or at least noble born, and he knows about it, but for some reasons he is hiding in Camelot, prtending to be just a servant. Do you know such fics? But no slash please (but can be arthur/fem!merlin)! Magic reveal inside would be nice, but not neccessary. ;D

Thanks in advance! ;)
