Trolls were creatures from Earth myths and legends. Trolls existed in the Land of Fiction. Some of them were converted into Cybermen. (AUDIO: Legend of the Cybermen) The Fomoir of Tír na n-Óg resembled trolls by design. (PROSE: Cat's Cradle: Witch Mark) The name was also used as an insult; Susan Foreman called the Master a troll. (PROSE: Legacy of the Daleks)
