The town is first explored in Chapter 4, where Meena and Maya Mahabala can purchase the best equipment available on the continent to prepare for their battle with Balzack in the hidden chamber of the Palais de Léon. After their defeat at the hands of Marquis de Léon, the sisters escape to the port with the Boarding pass given to them by the former king and head to Endor.
Shortly after the sisters fled, Marquis de Léon forbade any ships going to and from Havre Léon. Eventually, royal soldier Ragnar McRyan visited the prison and learned about The Marquis, prompting him to leave for the Palais. Following that, the sisters return along with the party of the Hero and learned about the Magic Key from the former weapon shop owner, who told them to ask about it in Aubout du Monde.
