Malbeth

Also called Malbeth the Seer, he profesised that Isildur's Heir would hold the Dead to their Oath. He did so in a song, or a poem, in the days of Arvedui. This is what he said to profesise this:

''Over the Land their lies a long Shadow, Westward reaching wings of darkness. The Tower Trembles; to the tombs of kings, doom approaches. The Dead awaken. For the Hour is come for the Oathbreakers: at the stone of Erech they shall stand again and hear there a horn in the hills ringing, whose shall be the horn, who shall call them from the grey Twilight, the forgotten people? The heir of him to whom they swore From the North shall he come, need shall drive him: He shall pass the door to the paths of the dead.''
