Balrog

Race of evil fire-demons in J. R. R. Tolkien's Middle-earth

A Balrog is a species of powerful demonic monsters in J. R. R. Tolkien's Middle-earth. One first appeared in print in his high-fantasy novel The Lord of the Rings, where the Company of the Ring encounter a Balrog known as Durin's Bane in the Mines of Moria. Balrogs appear also in Tolkien's The Silmarillion and his legendarium. Balrogs are tall and menacing beings who can shroud themselves in fire, darkness, and shadow. They are armed with fiery whips "of many thongs", and occasionally use long swords.
