In an expedition to the court of Mark, king of Cornwall and England, Riwalin, king in the land of the Parmenians, had become acquainted and subsequently passionately in love with Mark’s beautiful sister, Blancheflure. Later, as he was assisting Mark in a campaign, Riwalin became mortally wounded and was carried to Tintajole. Blancheflure, disguised as a beggar maid, hastened to his sickbed and saved Mark’s life through her devoted love. The lovers then fled together to his native land and Blancheflure was proclaimed as his consort. However, Morgan attacked Riwalin’s country and, the king entrusted the pregnant Blancheflure to his faithful retainer Rual. Rual placed the queen for safekeeping in the castle of Kaneel. Here she gave birth to a son and died as her husband fell in the battle against Morgan.
