The physician Dian Cecht replaced Nuada's arm with a working silver one and he was reinstated as king. However, Dian Cecht's son Miach was dissatisfied with the replacement so he recited the spell, "ault fri halt dí & féith fri féth" (joint to joint of it and sinew to sinew), which caused flesh to grow over the silver prosthesis over the course of nine days and nights.[21][22] However, in a fit of jealous rage Dian Cecht slew his own son. Because of Nuada's restoration as leader, Bres complained to his family and his father, Elatha, who sent him to seek assistance from Balor, king of the Fomorians.
