Glaurung was a very powerful and cunning dragon, and he at times used his abilities to achieve his desired ends without resorting to direct physical violence (at which he was equally proficient). Glaurung appears to have been more cunning than Gothmog, a contemporary in the hierarchy of Morgoth. Like Sauron, another of his contemporaries, it was his nature to trick and deceive, and to spread lies and deceptions so cleverly that they could not be discovered until it was too late. In this manner, he accomplished much more damage than he could have with brute force, and caused the destruction of the Elven stronghold of Nargothrond and the suicide of mankind's greatest hero to date, Túrin Turambar. He caused amnesia in Túrin's sister Nienor, and since they had never met, they eventually married. Glaurung himself was slain by Túrin's blade Gurthang before he committed suicide. In J. R. R. Tolkiens fictional universe of Middle-earth, Gothmog was the Lord of the Balrogs and the High-Captain of Angband, one of the chief servants of the Dark Lord Morgoth with a rank equal to that of Sauron. ...

Glaurung was called Father of Dragons. It is not known with certainty, but it is largely suspected that he sired the rest of his race (or at least of his own sub-species, the Úruloki: wingless firebreathing dragons). He was bred by Morgoth from some unknown stock and was the first dragon to appear outside of Angband. This first appearance occurred during the Siege of Angband in 265(first age), when he came forth to attack, but too early because he was still young and immature. He was defeated and driven back to Angband by mounted Elven archers. See Angband (game) for the computer game. ...

After the sack of Nargothrond, he made a nest of treasure in the abandoned tunnels of the city. It is likely that he is the dragon that appears in Tolkien's poem "The Hoard" in The Adventures of Tom Bombadil, which seems to be based on the events at Nargothrond. The memory of Glaurung lives on in the many creatures that he apparently sired.
