Burglar/Bad Merlin?

[seizethebutt]

I was wondering if there are any fics where Merlin is a burglar like Robin Hood or something. Pretty sure I found something like that at some point, but I lost track of it.
The other thing is a fic where Merlin is evil and Arthur changes him or something along those lines.
Obviously they would both be AU. Either Canon era or future is fine. Can be slash, I honestly don't mind.
Thank you!
