Turgon is a son of Fingolfin and a member of the Noldor Elves, who play a significant role in the history of Middle-earth. Turgon is notable for his foresight in creating Gondolin as a refuge from the dark forces of Morgoth. His reign is marked by peace and prosperity, but ultimately, Gondolin falls due to betrayal.
