"Upon the crown of Túna the city of the Elves was built, the white walls and terraces of Tirion; and the highest of the towers of that city was the tower of Ingwë, Mindon Eldaliéva, whose silver lamp shone far out into the mists of sea. Few are the ships of mortal Men that have seen its slender beam."
