Ostoher was the son of Anardil of Gondor and the seventh King of Gondor.



In the year TA 420 he began rebuilding Minas Anor. After the work was finished, he chose Minas Anor as his summer residence (instead of Osgiliath), and his heirs continued this tradition.



In TA 490, Gondor was first attacked by Easterlings and the King's son, Tarostar, drove them off and eventually defeated them.



Ostoher ruled Gondor for 81 years, from TA 411-492, and was succeeded by his son Tarostar, later known as Rómendacil I.
