Nuada Airgetlám

Nuada Silver-arm was the first king of the Tuatha Dé Danann.
Remembered as an honest and judicious ruler. Connected with hunting.
King for seven years before the arrival at Ireland, meeting the Fir Bolg there, conquering them but leaving them Connacht.
Demoted by the loss of his arm, he was replaced by Bres, but came back once he had gotten a new arm of silver, seven years later, and ruled for twenty more years. Died in combat with the Fomori, but he had already relinquished the title to Lugh.
