what is the creature in the mines of moria
Balrog Balrogs /ˈbælrɒɡz/ are fictional creatures who appear in J. R. R. Tolkien's Middle-earth legendarium. Such creatures first appeared in print in his novel The Lord of the Rings, where the Fellowship of the Ring encounter one known as Durin's Bane in the Mines of Moria. Balrogs figured in Tolkien's earlier writings that appeared posthumously in The Silmarillion and other books.
