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.
