Merlin leaves Camelot?

Not something I can look up in tags, I'm interested in any fics where Merlin leaves Camelot. I'm not to picky about pairing, time frame (as long as its canon era), forced or volentary or even a specific reason why (although I did read a very small on recently where Merlin just got fed up that was pretty good). Any help you can give would be great.
