Netflix is setting up a prequel world for 'The Witcher'. The developing six-part limited series will go by the title 'Blood Origin'. 'Blood Origin' will detail the origins of the very first Witcher, and the events that lead to the pivotal “conjunction of the spheres,” when the worlds of monsters, men, and elves merged to become one. It dates back to the elven world — 1200 years before the world of “The Witcher”. Declan de Barra, one of the writers of the first season of 'The Witcher' will double as an executive producer and showrunner for the prequel alongside long-running executive producer Lauren Schmidt Hissrich, who has executive produced the first and the upcoming second season of ‘The Witcher'. Joining them on the ep bench are Jason Brown and Sean Daniel from Hivemind and Tomek Baginski and Jarek Sawko from Platige Films. Writer of the original 'Witcher' book series, Andrzej Sapkowski on which 'The Witcher' show was based will serve as creative consultant to the prequel. “As a lifelong fan of fantasy, I am beyond excited to tell the story ‘The Witcher: Blood Origin. A question has been burning in my mind ever since I first read ‘The Witcher’ books: What was the elven world really like before the cataclysmic arrival of the humans? I’ve always been fascinated by the rise and fall of civilizations, how science, discovery, and culture flourish right before that fall,” disclosed de Barra. “I am so thrilled to collaborate with Declan and the Netflix team on ‘The Witcher: Blood Origin.’ It’s an exciting challenge to explore and expand the Witcher universe created by Andrzej Sapkowski, and we can’t wait to introduce fans to new characters and an original story that will enrich our magical, mythical world even more,” said Schmidt Hissrich. Casting details are currently unknown. Production for the second series installment of 'The Witcher' is set to begin in the U.K. come August. Sapkowski commented: “It is exciting that the world of Witcher as planned in the very beginning is expanding. I hope it will bring more fans to the world of my books.”
