Where now are the Dúnedain, Elessar, Elessar?
Why do thy kinsfolk wander afar?
Near is the hour when the Lost should come forth,
And the Grey Company ride from the North,
But dark is the path appointed to thee:
The Dead watch the road that leads to the Sea.
Referring to the  “All That Is Gold Does Not Glitter” poem 
 The Dúnedain are roving rangers, but also the descendents of Númenóreans. Thus Galadriel proclaims it is nearly time that the “lost” rangers, and particularly Aragorn, return to their rightful status as rulers of men.
