In J. R. R. Tolkien's legendarium, Arda is the name given to the Earth in a period of prehistory, wherein the places mentioned in The Lord of the Rings and related material once existed. It included several seas and oceans, and the continents of Middle-earth, the Dark Lands, and Aman (The Undying Lands), as well as the island of Numenor and other lands, left largely unnamed by Tolkien.*
