Good guess! I too think of Amandil... "Lord of Andúnië and father of Elendil. Though an Elf-friend, he was for many years a friend and counsellor to King Ar-Pharazôn. Dismissed by Sauron, he sailed into the West to seek the pardon of the Valar for the misdeeds of the Númenóreans; his fate is unknown." Ar-Pharazon: "Twenty-fifth and last King of Númenor. He assailed Mordor and brought Sauron back to Númenor as a hostage, but Sauron seduced him, and persuaded him to sail on Valinoritself. As punishment for this act, the island of Númenor sank beneath the waves of the Great Sea."
