<P> Apparently Dwarves as a race began to dwindle by the end of the Fourth Age, for their women made up less than a third of their population . Often, the women would not desire to marry, or want a husband that they couldn't have . Similarly, many male Dwarves were too engrossed in their crafts and did not have the time to take a wife and have children . </P> <P> The ultimate fate of Dwarves is unclear . Tolkien lamented they were "a race abandoned to folk - tales, where at least a shadow of truth is preserved, or at last to nonsense - stories in which they have become mere figures of fun ." </P> <P> Gandalf, Frodo Baggins and Boromir departed Middle - earth (in one way or another) at the end of the Third Age, leaving six members of the Fellowship of the Ring surviving in the Fourth Age . </P> <P> Aragorn, crowned King Elessar, ruled the Reunited Kingdom of Arnor and Gondor until his death in the 120th year of the Fourth Age . He ruled with his Queen Arwen, and their son Eldarion succeeded Aragorn on his death . Aragorn and Arwen also had multiple daughters; Arwen later travelled to the ruins of Lothlorien and there died . </P>
