Synopsis
Merlin continues in his destiny to protect Arthur and Camelot from any enemies. He must keep his magic a secret because magic is still banned in Camelot. Dark forces are still threatening Camelot so Merlin must defend the kingdom at any cost.

Arthur’s romance with Gwen grows stronger and new characters and friends are introduced. Characters like the Great Dragon and Lancelot return to help Merlin and Arthur defend Camelot.



Meanwhile, Morgana finally returns, having survived her poisoning by Merlin, and everyone is relieved and happy. Morgana, however, only wishes to see Camelot’s fall with the help her half sister Morgause, but only Merlin and Gaius know about this. Will everyone see Morgana for who she really is or will it forever remain a secret?
