Ar-Inziladun took power in a time of great darkness in Númenor; ever since Tar-Atanamir, every king had spoken against the Valar and questioned the policies laid out to them. Palantir, however, sought to repent the actions of his predecessors; he once again tended White Tree and followed the ancient practices. However, there was no response from the Valar; and Eressea could not be seen from the tower of Tar-Minastir.
A name in Quenya was inscripted in the Scrolls, as was with ancient practices. Palantir in Quenya means "far sighted," as Palantir indeed saw the destruction that would come to Númenor if it kept going down the path it was on. His daughter, Míriel was his official successor and would have followed his policies, but her rightful place as Queen of Númenor was usurped by her husband, Ar-Pharazôn.
