Magic Revealed - Poison
Starting at the beginning of Season 4, Lancelot and Merlin manage to close the rift without a sacrifice. With Arthur curious about magic, Merlin finds himself revealing his talents to the most trusted of the knights and to the prince. Together they decide that they will bring magic back to Camelot when Arthur becomes king. Also, a funny Merlin meme in every chapter. For no reason, just cause I liked them. And I don't own Merlin, obviously. Just the story.
