In days of old, Men and Elves and Dwarves built great cities and fortresses against the Shadow. Their names passed into legend Nargothrond and Gondolin, Nogrod and Belegost, vanished Nmenor while their ruins lie drowned beneath the western sea. Of all those mighty works, only one survived to the Third Age. Khazad-dm! Khazad-dm! Next to it, the cities of Gondor are but newly built! Even the oldest trees in Fangorn do not recall a time when the Dwarves did not toil under the mountain. Ancient are the halls of Durin.
