Merlin is an exceedingly powerful druid who appeared in the novel The Legacy of Merlin. He was also mentioned in the episodes "We're Off to See the Wizard" and "Sword and the City", but whether or not he actually existed in the series remains a mystery.


In The Legacy of Merlin, Merlin is presented as the most powerful Druid of all time. He was also the advisor to King Arthur. He lived in a high tower protected by magic in Camelot which can be accessed from the castle's hall.

He was married to Nyfein the Enchantress, more commonly known as "Viviane" and "Nimue" in modern times, and that he would have a son with her named Niall. Soon after Niall was born, his wife imprisoned him with her in a castle of magical glass and Niall was adopted by a noble family close to King Arthur whose parentage was kept secret from everyone. Merlin had long ago foreseen the fall of Camelot, and came to accept it.

Prue and Piper Halliwell traveled back in time to tell Merlin about his son's danger and asked him to give them the spell to help him return to his own time.

Physical Description

"A tall, gray-beared figure in a long blue robe stood above her on the stairs. Iron gray hair waved back from a high forehead. Deep-set eyes burned down at her from shaggy brows."
