Eithne
The High King’s warriors nominate his eldest son Ceart as heir, but his half-brothers Neart and Art accuse him of killing the king’s hound. Ceart’s former nurse Nuala reveals that the brothers committed the murder. The king sentences them to death, then pardons them at Nuala’s urging and names Ceart heir. During a hunt, the king follows a mysterious bird, revealed as Eithne, cursed into bird form by her father, the King of Tír na nÓg. Ceart defeats the gate’s guardian and Eithne’s father with a magic sword. Nuala is revealed as the king’s wife, cursed to mortal life during his anger; they reunite and the spell breaks. Ceart defeats his half-brothers in the contest for Eithne’s hand. After his father dies, Ceart becomes High King.
