Once upon a time, a plague of frogs visited the Sansretour Marsh. Duchess Ademarta declared a prize would be given to whomever freed the land of these accursed amphibians. Yet neither the knights errant nor the druids nor anyone else proved up to the task – until a poor raftsman named Flovive figured out a way. He serenaded the frogs with his violin and they, entranced by his melody, followed him out of the duchy. In memory of this event, the settlement where Toussaint's raftsmen dwell bears his name.
The Duchess Ademarta was credited for lifting the tradition of tourney to its current status in Toussaint. When the Duchess was unable to decide whom to wed, she organised a tourney for her suitors (described as having swarms of) to compete in. There, she could comfortably determine whom had the qualities she valued most in men - Strength, Valor and Cunning. However, in the end, she instead wedded the youngest son of Nilfgaard's reigning emperor, whom she had met on a journey south.
