After Arvedui the North-kingdom ended, for the Dúnedain were now few and all the people of Eriador diminished. Yet the line of the kings was continued by the Chieftains of the Dúnedain, of whom Aranthar son of Arvedui was the first. Arahael his son was fostered in Rivendell, and so were all the sons of the chieftains after him; and there also were kept the heirlooms of their house: the ring of Barahir, the shards of Narsil, the star of Elendil, and the sceptre of Annúminas [25].

[25] ...The sceptre of Númenor is said to have perished with Ar-Pharazôn. That of Annúminas was the silver rod of the Lords of Andúnië, and is now perhaps the most ancient work of Men's hands preserved in Middle-Earth. It was already more than five thousand years old when Elrond surrended it to Aragorn.
