The Kingdom of the Vale, once a flourishing and dominant land, fell into disarray long ago as the ruler's two sons engaged in a fierce battle releasing their Legendary creatures Reshiram and Zekrom, resulting in the disruption of the critical Dragon Force that sustained the kingdom. However, equilibrium was reinstated with the intervention of the Mythical Pokémon Victini and the sealing of the Dragon Force by the Sword of the Vale. Any attempts to move the Sword would bring destruction to the land. Damon, a descendant of the dispersed People of the Vale, endeavors to restore his forefathers' kingdom to its former grandeur. By successfully calling upon the Legendary Pokémon Zekrom, he removes the Sword of the Vale and harnesses the power of the Dragon Force. Meanwhile, Satoshi and his crew journey to Eindoak Town situated beneath the Sword of the Vale. As Damon's plan unfolds, they unite with Victini, the guardian of the Vale, to prevent the dreadful calamity that occurred a millennium ago from recurring.
