After something terrible occurs, Arthur, Gwen, Gwaine, and Lancelot take their turns in protecting their protector. Merlin's the one in trouble, now, and it's up to them to save him.
Instead of Guinevere, Arthur falls in love with a female version of Merlin. The problem is that he wasn't the only knight. Who will win Merlin's heart?
I got this idea from our lovely sherlockian_demigod!
