TL;DR They are completely separate stories and universes, but before anyone gets upset at that statement, let me provide a chronology of publication and different understandings of “Witcher” throughout the decades: Books The Witcher began with a short story “Witcher” published December 1986 in the speculative fiction magazine Fantastyka as an entry to a story-writing contest, coming in third place. Author Andrzej Sapkowski was not expecting the grand fan response it received, and there was soon a demand for more “Witcher” short stories — more were published in later monthly publications of Fantastyka diring the early 1990s, such as “A Grain of Truth,” “The Lesser Evil,” “A Question of Price,” “Bounds of Reason,” and “Shard of Ice.” (Note: “Road of No Return” was the second story Sapkowski had published in Fantastyka, but it was only incorporated into Sapkowski’s “Witcher universe” later, when a character from this short story turns out to be connected to Geralt (no spoilers here :)). The Witcher had some early adaptations even then in the early 90s, in the form of comics by illustrator Bogusław Polch. Sapkowski had challenges getting his stories published in book form, due to a reluctance from publishers to “take a chance” on selling a new story from a Polish author — IIRC as it was told by Sapkowski in interviews, they preferred to publish translations of already-established fantasy, e.g. Tolkien. Sword of Destiny was the first book, published in 1992. The Last Wish (which is first in the suggested reading order, and chronologically takes place before Sword of Destiny, which is second in the reading order) was actually published after. These first two books — Sword of Destiny and The Last Wish — are anthologies of Witcher short stories, some which were published in Fantastyka and some not-before-published ones. The Witcher then became a saga as Sapkowski decided to commit to writing in this universe, and five novels emerged: Blood of Elves, Time of Contempt, Baptism of Fire, Tower of the Swallow, and Lady of the Lake. Lady of the Lake, the last book, was published in 1999. Games The games by CD Projekt Red were created beginning in October 2007 with the first game Witcher, and take place after the ending of Sapkowski’s saga (e.g., after the events of Lady of the Lake). This directly contradicts the ending of the saga, because [Major Spoiler Alert] Geralt dies at the end of the books but CDPR created a story that works its way around this fact, taking advantage of a thematic concept introduced in the last book that legends never die, stories always continue, etc. and the ending incorporating surreal, mythological elements. The details of this story are fleshed out more in the second installment in CDPR’s trilogy, Witcher 2, where Geralt begins to lose his amnesia he suffered from in the first game and begins to remember what happened between Lady of the Lake and the first game. By Witcher 3, as you may imagine, he has recovered from his amnesia. Witcher 3 also incorporated the other two main characters of the book series — Yennefer and Ciri. The games are narratively a continuation—an adaptation of Sapkowski’s world, characters, settings, and more, but not of the books and stories themselves. For the most part, the reception by fans of the books is positive towards the games, even if it’s not “accurate to the books” at times. The reason for this is that CDPR were fans of the Witcher books and their work reflects this. There are tons of references to the books within the games, and the first game especially takes a lot of concepts and plot from the books, it being created as a kind of tribute. However, as an aside these positive feelings, it should be noted that Sapkowski wrote a complete saga and the “Witcher” as a story was closed after the final book, with no “continuations” — even Sapkowski’s standalone Witcher novel, Season of Storms, published in 2013, is a mid-quel, occuring in the chronology sometime inbetween the short stories. To weigh the “faithfulness to the books” of the games is a challenge. Atmospherically, visually, musically, and design-wise, they are generally very “Witcher” in spirit, and I think most fans would agree that the world CDPR creates for the Witcher reflects that of the books; however, narratively and story-wise, there are many inconsistencies between the games and books, so it’s really unfair to suggest that the story of the games are an inherently “canon” continuation of the books. The books were done when Sapkowski finished writing them. The games are thus a fanfiction, but a really good and generally accepted fanfiction, because they were made by actual fans. Netflix series During this entire time that I’ve gone over, The Witcher has been slowly becoming an international phenomenon, becoming known not only in Poland, not only in Czech Republic and Russia (where the majority of Sapkowski’s foreign readers lie), but across the world and particularly in English-speaking countries, the United States and the United Kingdoms. Streaming giant Netflix bought the rights to create a series using the “Witcher” name and released the first season of their series in December 2019. Many fans of Sapkowski’s Witcher were disappointed with this release, as the show removed a majority of stories and plot from the books and instead created their own story that directly contradicts information from the books. And this was the first season. Think of something like (reportedly) Season 8 of Game of Thrones, but instead of it being the last season, it was the first season of the series. To illustrate how terrible the first season was, they cut out the single most important story of all of the short stories—“Sword of Destiny”—the very titular story which is about how Geralt and Ciri meet and why they share the parent-child bond which will go on to define the entire series. The show creator, Lauren S. Hissrich, was famously quoted as saying she initially didn’t want to do the project, until Netflix assured her she would not have to follow the books: “(…) I’m not a fantasy writer, I don’t think I’m the right person to honor this. I dont know if I can give the fans what they want. And Netflix–I love them for this–they sort of pushed back and said, ‘Don’t worry about the fans. Remember, tell us the story that you would tell.'” Why The Showrunner For The Witcher Initially Said No To Netflix The Netflix show worsened in its second season, and went completely astray from the books. While the first season watered down, missed the point, or cut out a lot of important parts from the books The Last Wish and Sword of Destiny which they attempted to adapt, the second season did not seem to touch the book Blood of Elves at all—if you want to know how bad it is, here is my opinion: I think that they wasted their money, they didn’t need to buy the rights from Sapkowski to create this, because there is barely any similarity at all between this creation and his novels. Conclusion Each “Witcher” exists in its own separate world. This viewpoint is shared by Sapkowski himself: “(...) Adaptations with all the drawbacks of adaptation. You can not put a book and its adaptation on the same level, compare and combine them, because they are incomparable and unconnected. There are no contact points. The mystery for me is who invented this "recreating the spirit", attributed to adaptations. Even though adaptation was a masterpiece in its genre, the spirit of the book lives only in the book and is not transferable.” Sapkowski interviewed about fandoms and shitstorms, 2018 Adaptations are adaptations, they each exist in their own world. In some cases, they create an similar world to their original medium, in some cases they set the original medium on fire and we’re helpless to watch it. They are each separate universes. The characters may share the same names, look at least somewhat similar, and even resemble one another in their personalities and actions—but to think that the Geralt Sapkowski created, the Geralt CD Projekt Red created, and the Geralt Netflix created are all the same character would be very imprecise, dare I say—wrong. They’re all different, created by different authors, in different times, with different stories and motivations surrounding them. That doesn’t mean the fans can only like one of them, but it means that they’re not interexchangable, congruent. So, to answer your question, yes—each have their own different stories! Have fun exploring them. I’d recommend to check out the books ;)!
