Malvegil son of Celebrindor is best known for the fact that the Witch-king founded the realm of Angmar during his reign. Nearly seven hundred years after its foundation, Angmar and its allies would destroy his kingdom of Arthedain, but in Malvegil's time there is no record of any open warfare between the two nations.
Nonetheless, the emergence of Angmar saw evil things multiply in the eastern lands, driving a westward migration across Eriador. Notable among those travelling out of the east were the Hobbits, and it was during Malvegil's time as King that the main Hobbit settlement in Bree took place.
Malvegil ruled Arthedain for seventy-seven years, and was succeeded by his son, Argeleb I.
