During the reign of Ostoher, the seventh King of Gondor, that land suffered its first attack by the Easterlings. Over the years that followed, such wars against the East and the South would become commonplace, but this first assault was turned back by Ostoher's son Tarostar. In token of his success, Tarostar took the name 'East-victor' (Rómendacil), and so set a pattern that would repeat across the history of Gondor. After Tarostar Rómendacil's time, Kings who won a singular victory over Gondor's enemies would commonly take such a 'victor' name. Two of these defeated the Haradrim of the South, and thus named themselves 'South-victor' (Hyarmendacil) in an echo of Tarostar's historic achievement.
