Initially published in Polish, Sword of Destiny (1992) and The Last Wish (1993) are two novels created by Polish author Andrzej Sapkowski that collectively form the foundation of the Witcher series of novels. The novels follow the journey of Geralt of Rivia, a renowned monster hunter known as the Witcher, as he explores a morally ambiguous world filled with political strife and supernatural phenomena and dangers. On this journey, Geralt faces the challenges of his profession, including the notions of societal prejudice and moral dilemmas, pervasive issues both in the literary era of Romanticism and today. The Last Wish and Sword of Destiny had a significant impact on popular culture, serving as inspiration for the critically acclaimed video game adaptation series, starting with The Witcher (2007). Fantasy characters serve as blueprints for compelling video game protagonists, breathing life into interactive narratives. As the paper will show, the literary Geralt embodies the Byronic hero archetype, whereas the video game Geralt, embraces some and rejects other qualities of the Byronic hero archetype, resulting in a complex, atypical character that corresponds with contemporary audiences.
