Sustained by Lord and Light, the twin-headed lion reigns over the kingdom of Ivalice.
A year has passed since the loss of the Fifty Years’ War. The prince, though but two years of age, has ascended the throne, his father having been claimed by sudden malady. Too young to rule, the prince requires a regent, who would be king in all but name. The queen's brother, Duke Larg, had seemed the obvious choice for the regency. However,fearing the influence such an appointment would give the queen, the Council refused to back him. Instead, they appointed the king's younger cousin, Duke Goltanna, as regent.

Duke Goltanna and Duke Larg were both generals who had distinguished themselves during the Fifty Years' War. Duke Goltanna counts as ally the greater part of the aristocracy loyal to the Crown. However, the fallen nobility and free knights left in the aftermath of the Fifty Years' War have aligned themselves with Duke Larg. With Duke Goltanna under the banner of the Black Lion, and Duke Larg under that of the White, the stage is set for what history would one day record as the War of the Lions.
