Gottfried von Strassburg's Tristan follows a knight (named Tristan) and a queen (named Isolde) who live in the Middle Ages. Because of a love potion, the two are fated to fall in love with each other - going against all odds and societal norms. But being part of something which goes against societal norms is not exactly foreign to Tristan, who is a love-child.
Very quickly, Tristan learns that he is, in fact, the son of a man named Rivalin and is the thus the true lord of Parmenie. To that end, Tristan engages in a duel with the brother of an Irish queen, whom he kills but who wounds him.
It is then that Tristan first comes into contact with Queen Isolde, who he quickly courts. The two run into a number of issues during their courtship, however, including things like fiery and violent dragons, the law, and societal pressure.
