Tar-Minastir (Q. ‘Tower-watch’), son of Isilmo, was the eleventh King of Númenor (SA 1731-1869), and one of its greatest warriors. After his aunt, Queen Tar-Telperiën, passed away, he inherited the Sceptre of Númenor.
While he was King, war broke out between the Elves and Sauron; when he found out that Sauron’s armies were nearing Eriador and threatening the land of Lindon (ruled by Gil-galad), he sent a great navy to Elven-King’s aid (SA 1700). At this time, the Númenoreans still loved and welcomed the Elves, though Minastir did envy their freedom from death. As a result of Númenor’s aid, Sauron was forced to retreat and Gil-galad able to secure the peace in Eriador.
After ruling over Númenor for one hundred and thirty-eight years, Minastir passed the Sceptre on to his son, Tar-Ciryatan (SA 1869), and died four years later.
