If you thought the second season of The Witcher took certain liberties with the source material, just wait until you see the recent 4-episode spinoff show, Blood Origin, which basically changes everything you knew about the history of the Continent and the creation of the Witchers.
In fairness, Andrzej Sapkowski has hardly detailed that specific period in history. All we know for certain is that the Conjunction of the Spheres let loose the first monsters into the world, not to mention the first humans. Their onslaught was what caused the creation of the Witchers in the first place; a group of warriors enhanced with mutations and lethal potions that give them the necessary edge to face these beasts off.
Blood Origin completely retcons that history in favor of a new narrative, one that shows the first Witcher being born even before the Conjunction. The monster hunter in question, called Fjall, is also an Elf, and completely fertile if the series finale is anything to go by. These developments are causing a great deal of outrage in The Witcher fandom, who, at this point, are genuinely questioning the sanity of Netflix writers.
Sometimes, a vocal minority gets unnecessarily critical of a piece of art on social media. This is certainly not one of those times, which is why a lot of fans are wondering why some folks even bother with watching this show given the recent developments at Netflix.
You can watch all four episodes of The Witcher: Blood Origin on Netflix now, but if you were to ask the fandom, they’d just urge you to read the books instead.
