Glaurung

Glaurung the dragon, nicknamed the "Golden" or the "Great Worm of Angband" is the main antagonist in the novel The Children of Húrin. He was one of Morgoth's most noted captains in the first age, and one of the deadliest and most cunning villains in all Tolkien's literature.

This is part of an ongoing project in which I imagine some concepts for a fictitious film based on The Children of Húrin, the book written by John Ronald Reuel Tolkien but edited and finished by his son Christopher.
