The Witcher franchise is based on a series of novels of the same name by Polish author Andrzej Sapkowski. The video games take place after the books and feature the titular “witcher,” Geralt of Rivia, who is also the main character in Sapkowski’s works. The world of The Witcher series is heavily influence by Slavic mythology, and CD Projekt Red has carried this into their game adaptations.
Senior art producer Michał Krzemiński re-iterated this point, stating that the studio has woven Slavic cultural influences throughout the game right down to the designs of the buildings and villages. He said that the team also visited museums and pored through research material pertaining to Slavic history, folklore, and mythology to get ideas for the world of Wild Hunt.
