Ban of the Valar
From Tolkien Gateway
The Ban of the Valar was the ban placed by the Valar on the Númenóreans, that they should not sail so far west from their island that they could not see its coasts. The first King of Númenor who spoke against it was Tar-Atanamir, believing that reaching Aman would grant them Immortality. It was the breaking of the Ban by Ar-Pharazôn that led to the Downfall of Númenor.
