Merlin's last words (Merlin Fanfic)

Merlin receives a message. A new witch has arrived. Her name is Enchanted. A long lost soul created by the wise dragon more than a thousand years ago. She is immortal and nothing can kill her. Not even a sword with the dragon’s breath. Her mission is to help Merlin kill Morgana and defend Arthur. Yet to do so, she has to gain Arthurs trust and knowing she's a witch, she must be kept secret. Everybody thinks Enchanted was a myth but no, in fact she exists. Will Arthur ever trust Enchanted? Will she reveal to him her secret? Will she be backstabbed? What awaits her in the Kingdom of Camelot can be beyond her control.
