Zigor!
Fairies foretell a Norman invasion and betrayal by Zunbeltz, while promising that Sancho Garcés will lead the Basques. Zunbeltz tries to seize the crown and fails to kill the infant Sancho; later, he accuses Sancho of political and romantic betrayal. As San León promises deliverance, the Normans are defeated, and Zunbeltz’s remorse and violence culminate in his fatally wounding his daughter Lore.
