Geralt of Rivia helped Emhyr var Emreis (with the alias ‘Duny’) from being killed and lifting his curse. Duny, filled with gratitude, was willing to give the Witcher any reward he asked for. Geralt asked for the Law of Surprise, an oath-binding magical law that has unexpected results. It turned out that Duny’s bride Pavette was pregnant when this oath was taken and that the fate of the child, Princess Cirilla Fiona Elen Riannon and Geralt were forever entwined.
