Across the trilogy, Isildur shifts from a cautionary historical figure whose single act of mercy toward the Ring dooms Middle-earth, to a mythic founder whose long-dead oaths still shape the War of the Ring. In the first book he is remembered chiefly for cutting the Ring from Sauron’s hand and refusing to destroy it; by the third he is revealed as the king who bound the Dead to their oath at Erech, an oath Aragorn finally redeems. Thus the same man who preserved the Ring’s menace also planted the seeds of its ultimate defeat, his legacy bridging the ancient world and the present struggle.
Description
