Celtic mythology, aka Nuada Airgetlam the king of the Tuatha De Dannan he was wounded in the first battle of Moy Tura against the Formorians and lost his right hand. A king could only be whole, so he lost his kingship as well. Dian Cecht fashioned a silver hand but Bres succeeded him as king.

In some versions, the silver hand fashioned by Dian-cécht was sufficient to allow Nuada to be king, in other versions he had to wait until Airmed and Miach healed his arm completely.

While the business with his arm was getting sorted out, Bres did indeed take over as king, but he was tyrannical and unpopular; he was exiled as soon as possible, and Nuada replaced him, new arm in place.

Nuada was the chief god of the Tuatha Dé Danann, and was the god of healing, the Sun, childbirth, youth, beauty, ocean, dogs, poetry, writing, sorcery, magic, weapons, and warfare*, although he was not necessarily the head god in these areas. He married Macha, and fathered Tadhg and Echtghe (AKA Aughty). Both Nuada and Macha are slain by Balor. Nuada is also known as Nudd or Ludd.
