Evil Morgoth rules over a vast military power from his fortress of Angband. Ulmo, the Lord of Waters, opposes him. Central to this enmity of the gods is the city of Gondolin, built and peopled by Noldorin Elves who rebelled against their rule and fled to Middle-earth. Into this world comes Tuor, cousin of TÔurin. Guided unseen by Ulmo, Tuor sets out from the land of his birth on the fearful journey to Gondolin.
