Glaurung, in "The Silmarillion", is the Father of Dragons in Tolkien's legendarium, the first of the Fire-drakes of Angband. Tolkien wrote that Glaurung had four legs and no wings and could not fly, and sired the brood of Urulóki, wingless fire-breathing dragons. He was bred by Morgoth from some unknown stock and was the first dragon to appear outside of Angband. Glaurung is the main antagonist of "The Children of Húrin", and his deceptive actions led to the suicides of its main characters Túrin Turambar and Niënor Níniel.
