   Son of Eärnil II, and last King of Gondor. In his youth, he defeated the Witch-king of Angmar at the Battle of Fornost. The Witch-king returned to Minas Morgul, and issued a challenge to Eärnur, who answered it and, entering Minas Morgul, was lost. After him, the realm of Gondor was ruled by hereditary Stewards, the first of whom was Mardil Voronwë.
