Merlin is the court wizard of Camelot. He is Morgana le Fay's mentor.

Early Life
Merlin has been Uther Pendragon's court wizard for 29 years. When Uther banned magic in Camelot, Merlin was the sole exemption.

Season 1
Merlin warned Uther that his methods of wiping were making him enemies. When Morgana reported to him to become his apprentice, Merlin warned her to keep her magic secret. Reading a letter from Igraine, Merlin learned that Morgana had been sent to Camelot for her protection.

After Morgana was put in the dungeon for running afoul of Anna, Merlin freed her, though Morgana still had to spend time in the stocks.

Merlin later gave Morgana a book on magic under the condition that she keep it hidden.
