Merlin does some morally ambiguous things to protect Arthur. I'm looking for fics that explore Merlin's dark side and the things he's willing to do to keep Arthur safe, or where he's just a BAMF in general.
I don't want him be dark or hurtful towards Arthur- I just want Merlin being powerful and a badass and protecting Arthur at all costs.
Merlin/Arthur is great, and gen is wonderful too. Bonus points if it has h/c.
