Falastur

While Siriondil ruled as King of Gondor, his son Tarannon served as his father's Captain of the Hosts. He built Gondor great navies, and won victories and land along the coasts of Middle-earth, and especially in regions around the Mouths of Anduin. When he inherited the Kingship from his father, Tarannon took the name Falastur, "Lord of the Coasts", and became known to history as the first of Gondor's four Ship-kings.
