's fantasy universe of Middle-earth
was a Dúnadan
, elder son of Elendil
. In his youth Isildur stole a fruit of Nimloth
before it was cut down, preserving the line of the White Tree, and later planted a seedling in the new city of Minas Anor
. After Gil-galad
and Elendil fought and defeated Sauron
at the Siege of Barad-dûr
, but perished, Isildur cut The One Ring
from Sauron's finger. He was later slain in the Gladden Fields
by roaming orcs
and the Ring's treachery.
In the riddling rhyme "Seek for the Sword that was Broken" the Ring is referred to cryptically as Isildur's Bane.
