Quite similar, since both the show and the games are clearly made by people who revere the source material. The most successful and famous adaptation, however, is The Witcher trilogy of video games by the studio CD Projekt Red. Geralt’s print adventures are very popular in Poland - there have been comics, a TV show, movie, and tabletop role-playing game all based on Sapkowski’s work. I’m not! The Witcher is based on a series of books by Polish author Andrzej Sapkowski. Turning into a witcher is a grueling process called the Trial of the Grasses, and only about a third of those who undergo it survive.
Witchers are once-normal humans who got mutated by a combination of medieval science and magic, which made them superhuman (more Captain America than Superman) and able to take potions too toxic for normal people. Why are witchers rare? Can I be a witcher? Despite the fact that other witchers are out there, generally speaking, The Witcher almost exclusively deals with the adventures of Geralt of Rivia and the people he encounters. An early episode begins with Geralt hunting a monster that killed another witcher, and you will hear Geralt mention someone named Vesemir at one point - that’s the name of the witcher who trained him. Yes! Witchers are rare, but Geralt is not the only one.
Wow, we’re really starting at the beginning, huh? A witcher is a monster hunter for hire.
