House of the Hammer of Wrath
The House of the Hammer of Wrath was a kindred of Gondolin led by Rog during the Fall of Gondolin. They were great smiths and craftsmen, and reverenced Aulë. They carried great maces like hammers, and heavy shields, for they had strong arms. The device of this people was the Stricken Anvil, and a hammer that smites sparks about it; this was set upon their shields, for red gold and black iron was their delight. They had a great hatred for Morgoth and the Balrogs, and during the Fall of Gondolin they slew a number of the fell beasts, the first to slay any of the balrogs, though all of them perished in that battle.
