Annúminas-stone

Stone of Annúminas was one of the three palantíri of Arnor, the North-kingdom of the Dúnedain. Though it was counted one of the lesser of the seven Seeing-stones brought into Middle-earth, it was nonetheless the one used most often by the King in the north, and was preserved at Annúminas through the history of the realms of Arnor and its successor Arthedain.

When Angmar's forces overran Arthedain, its last King, Arvedui, saved the Stone of Annúminas, along with the palantír that had been kept in the Tower of Amon Sûl. With these and other heirlooms, he fled into the far north, where he was given shelter by the Lossoth, the Snowmen of the north. At last a ship from the Grey Havens came to rescue Arvedui, but after he had boarded, its hull was crushed by the ice, and all aboard were lost. The Stone of Annúminas, along with that of Amon Sûl, were lost in the shipwreck, and sank beneath the cold waters of the Icebay of Forochel.
