Dúnedain
In J. R. R. Tolkien's legendarium, the Dúnedain (singular: Dúnadan, "man of the west") were a race of Men descended from the Númenóreans who survived the sinking of their island kingdom and came to Eriador in Middle-earth, led by Elendil and his sons, Isildur and Anárion. They are also called the Men of the West and the Men of Westernesse (direct translations of the Sindarin term). They settled mainly in Arnor and Gondor.
The Westron name for Dúnadan was simply Adûn, "westerner", but this name was seldom used. This name was reserved to those Númenóreans who were friendly to the Elves: the other, hostile survivors of the Downfall were known as the Black Númenóreans.
