After the destruction of Númenor, Isildur and his brother Anárion fled to Middle-earth. They and their ships landed in the southern part of Middle-earth, where they founded the realm of Gondor. Isildur fought in the "Last Alliance of Elves and Men" under the command of his father Elendil. Isildur cut off the One Ring from Sauron's hand. Elrond and Círdan told Isildur to destroy the One Ring, but Isildur did not want to and kept it. It was decided that Isildur would rule the northern kingdom Arnor afer his father. When Isildur journeyed north, he and his company were attacked by Orcs. Isildur was killed and the One Ring was lost. His oldest sons Elendur, Aratan, and Ciryon were also killed. Isildur's youngest son Valandil became King of Arnor after him.
