Guerra del Anillo
Eärendil's son Elrond too chose elvish immortality, becoming known as Half-elven, and in the Third Age played an important role in The War of the Ring, as narrated in "The Lord of the Rings". Elros chose mortality, the gift of Men, founding the line of the Kings of Númenor; his descendant at the time of The War of the Ring was Aragorn, one of the Fellowship of the Ring, who married Elrond's daughter, Arwen.
