Ar-Adûnakhôr becomes King of Númenor
Meaning: The Lord of the West
Event Type: Political
Age: 2nd Age - Rings
He was the first King to take the sceptre with a title in the Adûnaic tongue; though out of fear (as aforesaid) a name in Quenya was inscribed in the Scrolls. But these titles were held by the Faithful to be blasphemous, for they signified "Lord of the West," by which title they had been wont to name one of the great Valar only, Manwë in especial. In this reign the Elven-tongues were no longer used, nor permitted to be taught; were maintained in secret by the Faithful; and the ships from Eressëa came seldom and secretly to the west shores of Númenor thereafter.
His name in Quenya was Tar-Herunúmen.
