The Fall of Gondolin

In the Tale of The Fall of Gondolin are two of the greatest powers in the world. There is Morgoth of the uttermost evil, unseen in this story but ruling over a vast military power from his fortress of Angband. Deeply opposed to Morgoth is Ulmo, second in might only to Manwë, chief of the Valar.

Central to this enmity of the gods is the city of Gondolin, beautiful but undiscoverable. It was built and peopled by Noldorin Elves who, when they dwelt in Valinor, the land of the gods, rebelled against their rule and fled to Middle-earth. Turgon King of Gondolin is hated and feared above all his enemies by Morgoth, who seeks in vain to discover the marvellously hidden city, while the gods in Valinor in heated debate largely refuse to intervene in support of Ulmo's desires and designs.

Into this world comes Tuor, cousin of Túrin, the instrument of Ulmo's designs. Guided unseen by him Tuor sets out from the land of his birth on the fearful journey to Gondolin, and in one of the most arresting moments in the history of Middle-earth the sea-god himself appears to him, rising out of the ocean in the midst of a storm. In Gondolin he becomes great; he is wedded to Idril, Turgon's daughter, and their son is Eärendel, whose birth and profound importance in days to come is foreseen by Ulmo.
