Den enda indikationen vi har på någon speciell tjänst Aragorn kan ha haft från Valaren är hans livstid, den längsta på mycket lång tid och en återgång till de gamla Númenórean Kings (betoning min):
It was the pride and wonder of the Northern Line that, though their power departed and their people dwindled, through all the many generations the succession was unbroken from father to son. Also, though the length of the lives of the Dúnedain grew ever less in Middle-earth, after the ending of their kings the waning was swifter in Gondor; and many of the Chieftains of the North still lived to twice the age of Men, and far beyond the days of even the oldest amongst us. Aragorn indeed lived to be two hundred and ten years old, longer than any of his line since King Arvegil; but in Aragorn Elessar the dignity of the kings of old was renewed.

Huruvida denna "speciella tjänst" sparkar in före eller efter sin stigning till tronen är inte okänd. Under Aragorns liv innan han blir kung Elessar, har vi ingen indikation på att Valaren hade något speciellt intresse för honom.
