Tauren (played by Cal Macaninch) was a sorcerer who led a gang of renegade wizards with the aim of bringing down Uther Pendragon. He enlisted the help of Gwen's father, Tom, to perform alchemy with the use of a magical stone but escaped when Tom was caught by the royal guards. He later conspired with Morgana to bring Uther to her father's grave where he could be killed by Tauren. Morgana angered at Uther's recent execution of Tom simply for participating in alchemy when he had no way of knowing what he was involved in, but Morgana had a change of heart as Uther apologised to her for ordering Tom's execution. Tauren then attacked Uther and was fatally wounded by Morgana. Most likely, Uther would have executed him for sorcery.
