The duel between Merlin and Edwin Muirden occurred after Edwin tricked Uther into making him the court physician so he could kill the king to avenge his parents’ death. Edwin poisoned Uther with one of the Elanthia Beetles, but before he could escape he confronted the former court physician, Gaius. Gaius attempted to attack Edwin with his magic, but he failed because he mispronounced the words of the enchantment. Edwin cast the right spell and threw Gaius against a wall. Edwin then used his powers to create a ring of flames with which he surrounded Gaius. Edwin’s intentions were to burn Gaius alive, just as his parents had died. Suddenly, Merlin entered Edwin’s room and asked him to release his mentor. Edwin offered Merlin a place at his side as ruler of the kingdom, but when he realised that the warlock was a potential threat to his plans he used telekinesis to throw an axe at Merlin. As the axe was coming towards Merlin, he ducked and used time magic to stop the weapon. Edwin cast a spell (Swilte, Merlin) to strengthen his control over the object, but Merlin, with a flash of his eyes, turned it around and hurled it back at Edwin. The axe killed him and his fire spell was broken, allowing Merlin and Gaius to save Uther (A Remedy to Cure All Ills).
Victory: Merlin
