Summary: Arthur Has Returned. Magic has come back to the world. And just as Merlin and Arthur are preparing for their wedding, an ancient foe strikes at Arthur from within. (In more ways than one) as they try to face this new threat, Merlin starts to reel, realizing that Arthur being immortal now means Arthur will have to face the pain of losing everyone he cares about, besides Merlin, again. Furthermore, Merlin realizes he himself has gotten closer to the new knights and sorcerers than he let himself get to anyone in hundreds of years... And he doesn't know how many more times he can take the pain of losing people he cares about. Soon, Merlin has to face the unthinkable, and an enemy that is fully willing to take advantage of his pain.
